Remittances (money sent home by migrants) to developing countries are estimated to have reached US$ 325 billion in 2010 (World Bank, 2011). These amounts reflect only officially recorded transfers, transferred through formal channels and calculated as the sum of three items of the Balance of Payments Statistics, namely: compensation of employees, workers’ remittances and migrants’ transfers (Salomone, 2006; Aggarwal et al. 2011). Unrecorded remittances could represent 50 to 100% of recorded flows (World Bank, 2006; Hagen-Zanker and Siegel, 2007).<p>Remittances are three times the size of official development assistance (ODA) and the second source of external funds after foreign direct investment (FDI) for developing countries. Given their weight in receiving countries’ economies and household livelihood in many developing countries (for instance, remittances flows represent more than 25% of Lesotho’ and Moldavia’s gross domestic product in 2008), there is increasing policy and research interest in remittances as development resource. Furthermore, unlike FDI and ODA, remittances have the particularity to be directly affected to families, even those in remote areas, where development funds don’t arrive (Shaw, 2006). The thesis addresses the relationship between microfinance and the impact remittances have on domestic investment in developing countries. <p>Like other sources of external finance, remittances allow the economy to invest in human and physical capital (health, education), which contribute to growth (Ziesemer, 2006; Acosta et al. 2008). However, as remittances may be either directly consumed (remittances allow households to smooth their consumption, see for instance Lucas and Stark, 1985 and Glytsos, 2005) or used to invest in physical and human capital, it appears that their impact on domestic investment is perceived to be low or limited, given the amount of money they represent each year. According to literature, this is due to the small share that is dedicated to the launch or the support of economic activities. Actually, the allocation between consumption and investment, which depends on various factors such as the level of dependence households have with remittances, the migrant gender, and the existence of a credit constraint, varies on average around 10-20% of remittances that are not directly consumed (Salomone, 2006; Sorensen, 2004; Orozco, 2004). In the thesis we focus on the share of remittances that is saved and wonder how to maximize its impact, whatever this share. We are interested in the role of microfinance institutions, as actors of the financial sector, on this issue. Actually, two recent contributions, Mundaca (2009), and Giuliano and Ruiz-Arranz (2009), stress the role of the development of the financial sector. More precisely, the thesis focuses on a set of questions or issues that may be important for the microfinance industry to consider when interested in remittances flows and the deposits they may generate. <p>Financial development is generally defined as “increasing efficiency of allocating financial resources and monitoring capital projects, through encouraging competition and increasing the importance of the financial system. In other words, the development is about structure, size and efficiency of a financial system” (Huang, 2006). A large line of research work provides evidence that development of a financial system is a key driver of economic growth. <p>King and Levine (1993) argue that greater financial development increases economic growth. Levine and Zervos (1993) shows that growth is related to stock market activity, among other variables. Levine (1999) finds a significant effect of determinants of financial intermediation on economic growth. Beck et al. (2004) find strong evidence in favor of the financial-services view which stresses that financial systems provide key financial services, crucial for firm creation, industrial expansion, and economic growth. Levine (1997), Levine et al. (2000), and Beck et al. (2000) also stress the impact of financial development on growth. There is also an empirical literature that argues that the expansion and the deepening of the financial system lead to higher investment (see for instance Rajan and Zingales, 1998; Demirgüç-Kunt and Macksimovic, 1998). <p>By providing financial services to people whom traditionally do not have access to financial institutions, microfinance institutions (MFIs) may contribute to increasing the size of the financial system in many developing countries. Actually, according to the CFSI’s 2011 report, the one thousand-plus MFIs that report to the Microfinance Information eXchange (MIX) have 88 million borrowers and 76 million savers. Total assets of these MFIs amount to US$ 60 billion (CFSI, 2011). <p>The quite recent literature on remittances, financial development and growth can be categorized under two main approaches (Brown et al. 2011). One approach explores the relationship between remittances and financial development, with a view to assessing their impact on the level of financial development in receiving countries. The underlying argument is that remittances potentially contribute to financial development through both demand- and supply- side effects: by increasing households’ demand for and use of banking services, and by increasing the availability of loanable funds to the financial sector. According to this approach which consider the direct relationship between remittances and financial development, remittances have an impact on both financial outreach and depth in receiving countries, respectively through the fostering of financial literacy among remittances receivers and through the increasing availability of funds (see for instance Gupta et al. 2009, Aggarwal et al. 2011, Brown et al. 2011). <p>The second approach examines the remittances – financial development relationship indirectly by investigating how the given level of financial development in a country affects the impact of remittances on growth. This growth-focused approach allows for interactions between remittances and financial development in estimating growth equations for remittances receiving countries. Within the set of studies related to this approach, two opposing positions have emerged. The first position hypothesizes that the greater availability of financial services helps channel remittances to better use, thus boosting their overall impact on growth. Remittances are seen as financial flows in search of good investment projects, and good financial institutions are needed to facilitate the channeling of remittances to such investments. In this sense, remittances and financial system are complements. This position is supported by Mundaca (2009) who find that financial intermediation increases the responsiveness of growth to remittances in Latin America and the Caribbean over the 1970-2002 period. Other few studies also argue that channeling remittances through the banking sector enhances their development impact (see for instance Hinojosa Ojeda, 2003 and Terry and Wilson, 2005). <p>The other position argues that remittances contribute to investment and growth by substituting for inefficiencies in credit and capital markets. Remittances provide an alternative source of funding for profitable investments by alleviating liquidity constraints. In this sense, remittances promote growth more in less financially developed countries by substituting for lack of credits from financial institutions. This hypothesis is supported by Giuliano and Ruiz-Arranz (2009) who argue that poor households use remittances to finance informal investment in poorly developed financial markets with liquidity constraints. In their study, they interact remittances with a measure of financial development in standard growth equations, for a sample of 73 countries over the 1975-2002 period. Ramirez and Sharma (2009) obtain similar results using data from 23 Latin American countries over the 1990-2005 period. <p>The thesis contributes to existing knowledge on this indirect, growth-focused approach. Given the two existing opposite views on remittances impact on investment and the level of financial intermediation (a high level of financial development implies a high level of financial intermediation), in the thesis we first analyze the relationship that links these variables. We then analyses questions related to microfinance institutions (MFIs), as financial intermediaries. <p>Our focus on microfinance is made from two different perspectives, leading to different research questions. First, from the demand or microfinance clients’ perspective, we question about the interest for them to have MFIs entering the money transfers market (through the money transfer facilities and/or financial products that may be directly linked to remittances). The underlying argument is that MFIs enter the remittances market by providing money transfer services because there is a need for such services (and for other financial services) from their (potential) clients who are remittances receivers and migrants. According to this point of view, MFIs can contribute to recycle remittances flows into the financial system by contributing to the financial inclusion of remittances receivers and migrants thanks to the supply of adapted financial products. The occurrence of this assumption can therefore be measured by considering the involvement of MFIs on the remittances market as a determinant of financial inclusion indicators. Second, from the supply or MFIs’ perspective, we question about the rationale for MFIs to enter the remittances market. Here, the underlying argument is that MFIs are interested in operating on the remittances market because working with migrants can potentially contributes to the improvement of their financial and social performances. According to this perspective, remittances market opportunities as well as MFIs’ characteristics will determine the offer of money transfer services by MFIs. This supply approach therefore leads to the consideration of money transfers activities in MFIs as depending on remittances market opportunities and institutional variables. <p>Therefore, our papers related to microfinance will be articulated around these two questions (interest for clients and rationale for MFIs to have MFIs operating on the money transfers industry) by focusing, as argued earlier, on the deposits resulting from remittances flows. <p>As a matter of facts, by studying the relationship between microfinance and remittances respectively through the demand and the supply perspective, we raise causality issues related to MFIs’ money transfer activities and their impacts on MFIs performances. Actually, MFIs’ characteristics such as the right to collect public savings, as a potential source of efficiency gains, may significantly determine the supply of a money transfer service (MFIs’ perspective), while a money transfer service may itself be the determinant of some MFIs’ performance indicators related to financial inclusion, such as the volume of deposits made by clients (demand approach). However, given currently existing data on MFIs’ involvement on the remittances market we cannot consider simultaneously both perspectives in order to implement causality treatment techniques. Actually, the indicator of MFIs’ involvement we will use in our regressions is time invariant, therefore we are not able to build instrumental variables for instance (such as lagged values of our variable of interest) to eliminate econometric issues in our regressions. Nevertheless, through these two approaches taken separately, we contribute to some extend to the knowledge by putting in perspective different issues at stake for the microfinance industry. <p>Before we tackle our research questions we have an introductory chapter related to remittances flows: what are their trends, determinants and characteristics? The chapter also includes the definition of money transfer activities that we will use in the thesis, as well as an overview of MFIs’ involvement on the money transfers market. <p>Then, our research framework is divided into 4 sub-questions. The first one, treated in Chapter 2, is about the relationship between our variables of interest. What is the impact of the financial sector development (FSD) on the remittances’ impact on investment? This chapter aims at stressing the relationship existing between financial intermediation and remittances’ impacts on investment, which motivated our focus on MFIs (as financial intermediaries between remittances and the formal economy) in the following chapters. We focus on two transaction costs that decline with FSD. The first is the “Cost of Bank Depositing”, henceforth CDEP, which measures the difficulties of savers, particularly the less well-off, of depositing their savings in the formal banking system. The second transaction cost is the “Cost of External Finance”, henceforth CEXF, which measures the marginal cost for the banking system of borrowing in global financial markets. This cost is notably associated with the robustness of the country’s financial sector. In a stylized model of the lendable funds market, we analyze how both these variables affect the marginal effect of remittances on investment. We test model’s propositions using country-level data on remittances, investment, and proxies for both CDEP and CEXF, on a sample of 100 developing countries. We perform empirical tests using both cross-section and panel-data with country fixed effects, over the period 1975-2004. The results demonstrate, theoretically and empirically, that remittances and ease of access to the banking sector act as complements to stimulate domestic investment, while remittances and external borrowing are substitutes. We find that remittances flows stimulate local investment, as a part of remittances indeed become banks’ deposits, which increases the availability of lendable funds, reduces the interest rate and stimulates investment. In terms of policy implication, results suggest that enhancing financial sector development is crucial as it allows remittances to better fuel domestic investment. This is even truer when the access to international funds is difficult or costly. Improving the financial inclusion of remittances receivers by developing domestic banks’ ability to collect their savings is then a straightforward recommendation to policymakers who want to improve remittances impact on investment. <p>The second question, developed in Chapter 3 is related to the demand perspective of the relationship between microfinance and remittances. We want to assess whether there is a need from remittances receivers for financial products that may be linked to remittances. We aboard this question by assessing whether the supply of MTA leads to higher volume of deposits mobilized by MFIs, meaning that MFIs actually contribute or succeed in turning remittances into deposits. Using an original database of 114 MFIs –operating in Latin America and the Caribbean (LAC), South Asia (SA), East Asia and the Pacific (EAP), and Africa–, we perform empirical tests to study whether MFIs are able to capture migrants’ savings thanks to their money transfer activity. We test the impact of money transfer activity on deposits, using the natural logarithm of deposits as explained variable. Our main result suggests that money transfer activity has a significant positive impact on savings collection. MFIs involved in the remittances market thus attract more savings than MFIs that are not involved in it, probably coming from migrants and remittances receivers who are in need of adapted financial services. This confirms the opportunity MFIs may represent as a tool or a channel to improve remittances impact on investment. In that sense, MFIs should then be encouraged to operate on the remittances market, and to design financial products dedicated to migrants and remittances receivers. <p>The third question, developed in Chapter 4, is related to the supply approach of the relationship between remittances and microfinance. More precisely, we try to identify factors that seem to explain the availability of such service in the scope of services provided by MFIs. In this chapter, we focus first on potential sources of efficiency gains linked to the money transfer activity as a rationale for diversification (i.e. the expansion of the offer). And second, using an original database of 435 MFIs –operating in Latin America and the Caribbean (LAC), South Asia (SA), East Asia and the Pacific (EAP), and Africa–, we perform empirical tests using cross-section over the year 2006, to identify which environmental and institutional parameters have an impact on the willingness of a MFI to provide a money transfer service. We test the impact of various variables that are related to one of the rationale for MFIs to enter the money transfer market, namely economies of scale and scope as a source of efficiency gains, on the probability to have a money transfer service provided by a given MFI. Our main result suggests that the size, as well as the fact that an MFI collects savings have a positive and significant impact on this probability, while the level of financial development negatively impact it. This confirms among other things that the ability to realize economies of scale through a potential increase of collected deposits may be a determinant of managers’ choice to diversify. Policies that contribute to reduce entry barriers in low financially developed countries should then, among other things, be encouraged to have MFIs fully playing their role of intermediaries between remittances and the (formal) economy. <p>The chapter 5 questions about the institutional consequences for MFIs to collect migrants’ savings. The aim of this chapter is to give an insight on the opportunity migrants’ money (including remittances) could represent for the microfinance industry as a source of stable medium- and long-term funds. It is therefore related to the supply approach and the motivation for MFIs to enter the remittances market by analyzing the impact of migrants’ deposits (which include remittances) on another potential source of efficiency gains, namely the internal capital market. Through a case study approach, this chapter is devoted to the analysis of funding risk in microfinance, comparing migrants’ and locals’ time deposits. Migrants’ time deposits are expected to be of longer term and more stable (in terms of early withdrawals) than locals’ deposits. This assumption had never been tested yet. Based on an original database of 7,828 deposit contracts issued between 2002 and 2008 by 12 village banks belonging to a major Malian rural microfinance network (PASECA-Kayes), we used the Cox proportional hazard model to identify the variables that have an impact on the probability to have early withdrawals, and the technique of re-sampling to calculate withdrawal rates and deposits at risk. Results from the Cox methodology suggest that the migration status is not a direct determinant for the probability to have an early withdrawal. However, this probability increases with the amount deposited and the term of the contract which are both higher for migrants compared to non-migrants. The re-sampling method results suggest that withdrawal rates are not the same for the two categories of depositors observed. We find higher withdrawal rate distributions for migrants than for locals. The value at risk is also higher on migrants’ deposits than on locals’ deposits. However, as migrants tend to deposit for longer term than locals, through the calculation of durations we have measured to which extend migrants’ deposits still have a positive impact on MFIs’ liabilities. It appears that migrants’ money has a marginal but positive impact on time deposits durations, either when considering early withdrawals, which impacts are very limited, except in 2007 (the worst year in terms of amount withdrawn early). As our results show that MFIs that receive migrants’ deposits are not necessarily better-off than without migrants’ money in terms of funding risk - and durations - this paper has stressed the importance of assessing more carefully the role of migrants for the microfinance industry. <p><p><p><p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Le tourisme est le fer de lance de l'économie balinaise. Mais, les fruits de cette économie du tourisme ne bénéficient pas à toutes les classes de la société balinaise. Cela est dû, entre autres, au manque à gagner lorsque cette industrie importe par exemple des produits ou des services pour répondre aux besoins des touristes (alimentation pour la restauration par exemple). Le calcul du manque à gagner pour l'économie balinaise n’a jamais été fait auparavant. Pour cela, cette recherche est nécessaire. Les objectifs de la recherche étaient : de calculer le manque à gagner pour l'économie balinaise dans le secteur du logement pour les touristes en micro-économie (niveau industriel) ; d'estimer le manque à gagner pour le tourisme balinais dans le secteur de l'hébergement touristique en macroéconomie (au niveau provincial) ; d'évaluer l'impact de la subvention gouvernementale et la réduction des importations dans l' industrie du tourisme, les opportunités d'emploi et la distribution des revenus ; d'évaluer la perception et le choix des touristes internationaux face aux offres de produits importés et locaux, et aussi d'évaluer l'opinion des touristes sur le constat : est-ce que les dépenses des touristes pendant leur voyage à Bali bénéficient à la société balinaise ? ; et d'évaluer les opinions des gestionnaires des hôtels sur l'utilisation des produits importés et des produit locaux pour la consommation des touristes ; de créer une stratégie afin de minimiser le manque à gagner dans le secteur du tourisme pour l'économie balinaise. La recherche est basée sur les approches quantitatives et qualitatives. Les données primaires ont été recueillies par la méthode du sondage sur quatre destinations touristiques, à savoir : Kuta, Nusa Dua, Sanur et Ubud, auprès d'un échantillon de 79 hôtels selon la méthode de probabilité proportionnelle à la taille qui est divisée en trois échantillons en grappes : hôtels classés 1, 2 et 3 étoiles ; hôtels classés 4 & 5 étoiles et hôtels privés (non-chain) ou appartenant à une chaine hôtelière (chain) ; hôtels non-classés. Nombre de répondants 600 touristes internationaux qui étaient en vacances à ce moment-là. Le calcul du manque à gagner dans l'analyse micro a été mené selon la méthode d'Unluonen et. al. (2011), tandis que l'analyse macro a été faite selon la méthode de Thorbecke (1988) en utilisant l'approche de la matrice de comptabilité sociale (MCS) de la province de Bali de l'année 2010. La perception et le choix des touristes internationaux vis-à-vis des produits importés et locaux ont été analysé selon le logiciel JMP tandis que les stratégies de la minimisation du manque à gagner dans l'économie touristique balinaise ont été créées selon la méthode de l'ISM (interpretive Structural Modelling). [...] Les touristes internationaux choisissent de façon significative les produits locaux et ils sont prêts à dépenser leur argent au bénéfice des populations locales. Les gestionnaires des hôtels sont prêts à utiliser les produits locaux tant que l’offre est suffisante pour remplacer les produits importés. Les stratégies pour minimiser le manque à gagner pour le tourisme à Bali : optimiser les potentiels des produits locaux ; développer l'agriculture et l' élevage, réduire les produits importés pour la consommation des touristes, augmenter l'exportation des produits locaux, augmenter la qualité des produits locaux ainsi que la qualité des ressources humaines locales, renforcer la société locale, inciter le gouvernement à mettre en œuvre une politique de minimisation du manque à gagner dans l'économie touristique, limiter les investissements étrangers dans le secteur du logement touristique, stabiliser les fluctuations des taux de change, augmenter le rôle du Ministère des affaires étrangères, du ministère de l'industrie, du Ministère du commerce ainsi que le rôle du Ministère du tourisme et de l'économie créative afin de réduire ledit manque à gagner. / Tourism has become the leading economic sector in Bali Province of Indonesia. However, the economic impacts of tourism have not been convinced to be full y beneficial for Balinese community. One of the reasons is tourism leakage that occurs when the industry imports both products and services to support tourism industry in Bali. So far, the amount of tourism leakage in Bali has not been calculated yet. Therefore, there is a need to ascertain the current amount of leakage in Bali tourism. The objectives of the study are: (i) to calculate the amount of tourism leakage from accommodation sector in Bali at micro (industrial) level; (ii) to calculate the amount of tourism leakage from accommodation sector in Bali at macro (regional) level; (iii) to evaluate the impacts of government subsidies and import reduction by accommodation sector on tourism leakage, job opportunity and income distribution; (iv) to evaluate the perception and preference of foreign tourists on imported and local products as well as the willingness of foreign tourists to spend their money to benefit of Balinese people; (v) to evaluate the points of view of hotel managers related to imported and local products as well as their willingness in reducing the use of imported product and (vi) to develop strategies in minimizing tourism leakage in accommodation in Bali. Research was designed through quantitative and qualitative approaches. Data was collected by using survey method at four main tourist destinations in Bali, namely: Kuta, Nusa Dua, Sanur and Ubud. There were 79 hotels selected based upon probability proportional to size sampling method which consists of three clusters namely 1,2,3 Star-rated, 4&5 Star-rated either chain and non-chain and Non Star-rated hotels. The number of respondents was 600 foreign tourists were selected as respondents. Calculation of tourism leakage on micro analysis was undertaken by using a method developed by Unluonen, et. al. (2011), meanwhile, on macro analysis was carried out by using a method proposed by Thorbecke ( 1988) which was based on the Social Accounting Matrix (SAM) of Bali 2010. Perception and preference of foreign tourists on imported and local products were analyzed by using JMP program, meanwhile, Interpretative Structural Modelling (ISM) was undertaken to develop strategies. The results show that based on the micro analysis, the highest tourism leakage of accommodation sector in Bali is at 4&5 Star-rated chain hotels (51.0 %), followed by 4&5 Star-rated non-chain hotels (22.7 %), 1,2&3 Star-rated hotels (12.0 %), Non-star rated hotels (8.8 %), and with the average leakage of 18.8 %. Based on macro analysis, tourism leakage of accommodation sector in Bali are as follow: (i) Leakage of Non Star-rated hotels is 2.0 %; (ii) Leakage of 1,2&3 Star-rated hotels is 15.7 %; (iii) Leakage of 4&5 Star-rated non-chain hotels is 7.1 %, (iv) Leakage of 4&5 Star-rated chain hotels is 55.3%; and (v) Average leakage of all types of accommodation is 19.5%. Foreign tourists significantly look for local products and are willing to spend their money for Balinese people. Hotel managers are willing to use local product as long as local products are available to substitute the imported products. Strategies for minimization tourism leakage are optimizing the potential of local products, develop agriculture and livestock; reduce the use of imported products for tourists, improve quality of local products and human resources, empower community, urge government to develop and implement supporting policies in minimizing tourism leakage, establish policy on restriction of foreign investment on accommodation in Bali, improve the role of Ministry of Foreign Affairs, Ministry of Industry, Ministry of Trade and Ministry of Tourism and Creative Economy. 7 Ps of marketing mix on service: product, price, place, promotion, people, process and physical evidence need to be implemented in order to support sustainable tourism in Bali

Cette thèse s’intéresse à la stabilité financière. Nous considérons plusieurs modèles économétriques visant à offrir une meilleure compréhension des perturbations pouvant affecter les systèmes bancaires et financiers. L’objectif ici est de doter les institutions publiques et réglementaires d’un éventail plus large d’instruments de surveillance. Dans le premier chapitre, nous appliquons un modèle logit visant à identifier les principaux déterminants des crises financières. En plus des variables explicatives traditionnelles suggérées par la littérature, nous considérons une mesure des coûts de transactions (l’écart acheteur-vendeur) sur les marchés financiers. Nos estimations indiquent que des coûts de transactions élevés sont généralement associés à des risques accrus de crises financières. Dans un contexte où l’instauration d’une taxe sur les transactions financières (TTF) ferait augmenter les coûts de transactions, nos résultats suggèrent que l’instauration d’une telle taxe pourrait accroître les probabilités de crises financières. Dans le second chapitre, nous analysons la formation des risques financiers dans un contexte où le nombre de données disponibles est de plus en plus élevé. Nous construisons des prédicteurs de faillites bancaires à partir d’un grand ensemble de variables macro-financières que nous incorporons dans un modèle à variable discrète. Nous établissons un lien robuste et significatif entre les variables issues du secteur immobilier et les faillites bancaires. Le troisième chapitre met l’emphase sur la prévision des créances bancaires en souffrance (nonperforming loans). Nous analysons plusieurs modèles proposés par la littérature et évaluons leur performance prédictive lorsque nous remplaçons les variables explicatives usuelles par des prédicteurs sectoriels construits à partir d’une grande base de données. Nous trouvons que les modèles basés sur ces composantes latentes prévoient les créances en souffrance mieux que les modèles traditionnels, et que le secteur immobilier joue à nouveau un rôle important. / The primary focus of this thesis is on financial stability. More specifically, we investigate different issues related to the monitoring and forecasting of important underlying systemic financial vulnerabilities. We develop various econometric models aimed at providing a better assessment and early insights about the build-up of financial imbalances. Throughout this work, we consider complementary measures of financial (in)stability endowing hence the regulatory authorities with a deeper toolkit for achieving and maintaining financial stability. In the first Chapter, we apply a logit model to identify important determinants of financial crises. Alongwiththetraditionalexplanatoryvariablessuggestedintheliterat ure, weconsider a measure of bid-ask spreads in the financial markets of each country as a proxy for the likely effect of a Securities Transaction Tax (STT) on transaction costs. One key contribution of this Chapter is to study the impact that a harmonized, area- wide tax, often referred to as Tobin Tax would have on the stability of financial markets. Our results confirm important findingsuncoveredintheliterature, butalsoindicatethathighertransactioncostsaregenerally associated with a higher risk of crisis. We document the robustness of this key result to possible endogeneity effects and to the 2008−2009 global crisis episode. To the extent that a widely-based STT would increase transaction costs, our results therefore suggest that the establishment of this tax could increase the risk of financial crises. In the second Chapter, we assess the build-up of financial imbalances in a data-rich environment. Concretely, we concentrate on one key dimension of a sound financial system by monitoring and forecasting the monthly aggregate commercial bank failures in the United States. We extract key sectoral predictors from a large set of macro-financial variables and incorporate them in a hurdle negative binomial model to predict the number of monthly commercial bank failures. We find a strong and robust relationship between the housing industry and bank failures. This evidence suggests that housing industry plays a key role in the buildup of vulnerability in the banking sector. Different specifications of our model confirm the robustness of our results. In the third Chapter, we focus on the modeling of non-performing loans (NPLs), one other dimension along with, financial vulnerabilities are scrutinized. We apply different models proposed in the recent literature for fitting and forecasting U.S. banks non-performing loans (NPLs). We compare the performance of these models to those of similar models in which we replace traditional explanatory variables by key sectoral predictors all extracted from the large set of potential U.S. macro-financial variables. We uncover that the latent-componentbased models all outperform the traditional models, suggesting then that practitioners and researchers could consider latent factors in their modeling of NPLs. Moreover, we also confirm that the housing sector greatly impacts the evolution of non-performing loans over time.

L'objectif premier de cette thèse est d'examiner la relation entre la valeur boursière de la firme et les chiffres comptables divulgués en matière des régimes de retraite à prestations déterminées (RRPD). Plus particulièrement, nous examinons la perception des investisseurs des surplus et déficits de capitalisation. De plus, nous étudions la discrétion managériale dans le choix des hypothèses actuarielles ainsi que la perception des investisseurs de ces choix actuariels. Nos résultats montrent que les investisseurs tiennent compte des actifs et des obligations de retraite lors de la détermination des prix des titres et qu'ils considèrent respectivement l'excèdent et le déficit de capitalisation comme actif et passif de la firme promotrice des RRPD. De plus, nos résultats suggèrent que les dirigeants utilisent leur discrétion managériale dans le choix des hypothèses actuarielles et que les investisseurs y sont conscients. En effet, ces derniers réajustent à la baisse (hausse) la valeur boursière de la firme lorsque les dirigeants choisissent des hypothèses actuarielles libérales (conservatrices).

La thèse porte sur la problématique de l’efficience du financement intermédié des processus de croissance et de développement économiques. Elle s'intéresse d’une part à la résolution des problèmes d’inefficience liés à la présence d’asymétries informationnelles et de l’incertitude sur les marchés du crédit grâce aux mécanismes réputationnels mis en œuvre dans le cadre des relations de long terme banques-emprunteurs et d’autre part, aux conditions dans lesquelles ces mécanismes peuvent émerger et se développer, en particulier dans un pays en développement comme le Cameroun.La thèse a donc une portée à la fois conceptuelle, empirique et normative.En premier lieu, nous avons cherché à alimenter le débat théorique sur la pertinence et l'intérêt du mécanisme réputationnel dans le processus d’intermédiation bancaire. Nous montrons que, contrairement aux modèles habituels d’intermédiation de la théorie d’agence, où les mécanismes de sanctions ou de coercitions judiciaires restent souvent inefficaces et coûteuses, le caractère auto-exécutoire du mécanisme de la réputation suffit seul à garantir l’efficacité de son fonctionnement. De plus, le mécanisme réputationnel nous semble mieux concilier deux conceptions opposées du comportement des acteurs que sont l’homo economicus et l’homo sociologicus. De ce fait, ce mécanisme est susceptible de constituer un cadre d'analyse intéressant pour la modélisation des comportements bancaires notamment dans le contexte des PED africains où les incertitudes restent exacerbées et où prédominent des rationalités économiques beaucoup plus fondées sur les valeurs. En second lieu, les résultats de notre enquête statistique de terrain permettent de montrer qu'au Cameroun, par rapport aux Institutions Financières Décentralisées (IFD) comme la MicroFinance, les Institutions Financières Formelles (IFF) semblent accorder une moindre importance aux pratiques réputationnelles dans leur comportement d'allocation des capitaux, en particulier aux PME. Ceci est susceptible d'apporter une des meilleures explications au différentiel de performance micro-économique, se situant ici à l'avantage des IFD.Enfin, la même enquête nous permet de mettre fortement en évidence l'existence de nombreux facteurs à la fois internes et externes empêchant aux deux catégories de banques une meilleure prise en compte du mécanisme réputationnel. Ce constat nous conduit à proposer des axes ou pistes de réflexion, à formuler et à justifier un ensemble de recommandations à la fois organisationnelles, institutionnelles et réglementaires associées. Ceci dans l’objectif de construire un système bancaire camerounais plus fiable et plus solide en incitant les banques à mieux intégrer les pratiques réputationnelles dans leur jugement d'octroi de crédit aux emprunteurs. / This thesis focusses on the problematic of the efficiency of intermediate finance on the economic growth and development processes. It concerned, on one hand, the resolution of inefficiency problems resulting from the presence of asymmetric information and uncertainty involved credit markets when reputational mechanisms implemented through banks-borrowers long-term relationships are used and, on the other hand, the conditions in which these mechanisms could emerged and expanded, in particular in a developing country such as Cameroon.The thesis thus has, at the same time, conceptual, empirical and normative purpose First of all, we tried to enrich the theoretical debate about relevance and interest of the reputational mechanism relating banking intermediation process. We show that, while in the models of agency where judicial penalties and pressures mechanisms are often ineffective and expensive, only the auto-enforceable character of the reputational mechanism is enough to guarantee its efficacious functioning. Furthermore, for us, the reputational mechanism seems better to reconcile the two usual opposite conceptions of agents behaviors that are homoeconomicus and homosociologicus. Therefore, this mechanism might constitute an interesting analysis framework for modeling banking behavior, in particular in the context of African economies where uncertainties remain aggravated and where much more economic rationalities based on the values prevail.Secondly, our statistical survey issues clearly shows that in Cameroon, with regard to decentralized financial institutions (DFIs) like Microfinance unities, formal financial institutions (FFI) seem to attach less importance to reputational practices in their capital allowance behaviour, especially to small and medium-sized enterprises (SMEs). This is likely to provide a better explanation of the differential micro-economic performance, situated here to the advantage of DFI.Finally, the same above mentioned survey strongly reveal the existence of many both internal and external factors preventing both categories of banks in a better consideration of reputational mechanisms. We then proposed axes or lines of reflection, formulated and justified a set of corporate, institutional and regulatory associated recommendations. This with the aim to build a more reliable and more solid Cameroonian banking system by inciting banks to better integrate reputational practices in their judgment of granting credits to borrowers.

La divulgation d’informations sur les risques est une problématique centrale de la communication des entreprises cotées. De nombreuses dispositions réglementaires ont été mises en œuvre aux Etats-Unis et en Europe pour promouvoir la transparence sur les risques et les dispositifs de contrôle mis en place pour leur gestion. Les exigences de certification de l’efficacité de ces dispositifs conduit à la question de savoir si ou comment les entreprises non-financières françaises, ayant une double cotation aux Etats-Unis et en France, sont conformes à ces règlementations. Dans ce contexte, il est soutenu que la mise en évidence des différents niveaux de formalisation des dispositifs de contrôle des risques, à travers la communication des entreprises, permet de dégager des typologies originales de mise en conformité et de gouvernance des organisations. La démarche de recherche adoptée est basée sur l’étude de cas longitudinale qui permet de suivre les entreprises du lancement des projets de mise en conformité, à la stabilisation des processus de production de la certification des procédures de contrôle des risques. Les données recueillies (entretiens, rapports annuels) font l’objet d’une analyse de contenu à travers le COSO2. Une seconde étape est leur traitement statistique pour discriminer les réponses stratégiques dans le temps et entre entreprises. Les observations empiriques mettent en exergue différentes réponses stratégiques en fonction de deux périodes et des préoccupations économiques et stratégiques des entreprises. / Risk oriented disclosure is a central issue of listed companies communication. Many Risk-based regulations have been implemented in the US and Europe to promote transparency about risks and controls mechanisms. Under the requirements of the SOX, executives must certify the public company’s financial results (section 302) and have to issue a report on the effectiveness of the company’s internal controls over financial reporting (section 404). The increase of mandatory risk reporting leads to the question of whether or how the French non-financial companies cross-listed in the US and France are compliant with these regulations. In this context and across corporate communication, it is argued that different levels of risk control’s formalization can highlight original typology of compliance and corporate governance. This research uses a longitudinal case study in order to explore the implementation of risk control measures and the risk narrative disclosure strategies to enhance organizational legitimacy. The collected data (interviews, risk disclosures within annual reports) are subject to a content analysis through COSO2. A second step is a statistical analysis to discriminate strategic responses over the time and between companies. Empirical observations point to different strategic responses to institutional processes based on two periods as well as economic and strategic business concerns. The first phase shows that risk control process is structured in order to build the auditability of organization. While, in the second phase companies develop different strategic responses more consistent with their concerns.

Le contenu de cette thèse est divisé de la façon suivante. Après un premier chapitre d’introduction, le Chapitre 2 est consacré à introduire aussi simplement que possible certaines des théories qui seront utilisées dans les deux premiers articles. Dans un premier temps, nous discuterons des points importants pour la construction de l’intégrale stochastique par rapport aux semimartingales avec paramètre spatial. Ensuite, nous décrirons les principaux résultats de la théorie de l’évaluation en monde neutre au risque et, finalement, nous donnerons une brève description d’une méthode d’optimisation connue sous le nom de dualité. Les Chapitres 3 et 4 traitent de la modélisation de l’illiquidité et font l’objet de deux articles. Le premier propose un modèle en temps continu pour la structure et le comportement du carnet d’ordres limites. Le comportement du portefeuille d’un investisseur utilisant des ordres de marché est déduit et des conditions permettant d’éliminer les possibilités d’arbitrages sont données. Grâce à la formule d’Itô généralisée il est aussi possible d’écrire la valeur du portefeuille comme une équation différentielle stochastique. Un exemple complet de modèle de marché est présenté de même qu’une méthode de calibrage. Dans le deuxième article, écrit en collaboration avec Bruno Rémillard, nous proposons un modèle similaire mais cette fois-ci en temps discret. La question de tarification des produits dérivés est étudiée et des solutions pour le prix des options européennes de vente et d’achat sont données sous forme explicite. Des conditions spécifiques à ce modèle qui permettent d’éliminer l’arbitrage sont aussi données. Grâce à la méthode duale, nous montrons qu’il est aussi possible d’écrire le prix des options européennes comme un problème d’optimisation d’une espérance sur en ensemble de mesures de probabilité. Le Chapitre 5 contient le troisième article de la thèse et porte sur un sujet différent. Dans cet article, aussi écrit en collaboration avec Bruno Rémillard, nous proposons une méthode de prévision des séries temporelles basée sur les copules multivariées. Afin de mieux comprendre le gain en performance que donne cette méthode, nous étudions à l’aide d’expériences numériques l’effet de la force et la structure de dépendance sur les prévisions. Puisque les copules permettent d’isoler la structure de dépendance et les distributions marginales, nous étudions l’impact de différentes distributions marginales sur la performance des prévisions. Finalement, nous étudions aussi l’effet des erreurs d’estimation sur la performance des prévisions. Dans tous les cas, nous comparons la performance des prévisions en utilisant des prévisions provenant d’une série bivariée et d’une série univariée, ce qui permet d’illustrer l’avantage de cette méthode. Dans un intérêt plus pratique, nous présentons une application complète sur des données financières. / This thesis is structured as follows. After a first chapter of introduction, Chapter 2 exposes as simply as possible different notions that are going to be used in the two first papers. First, we discuss the main steps required to build stochastic integrals for semimartingales with space parameters. Secondly, we describe the main results of risk neutral evaluation theory and, finally, we give a short description of an optimization method known as duality. Chapters 3 and 4 consider the problem of modelling illiquidity, which is covered by two papers. The first one proposes a continuous time model for the structure and the dynamic of the limit order book. The dynamic of a portfolio for an investor using market orders is deduced and conditions to rule out arbitrage are given. With the help of Itô’s generalized formula, it is also possible to write the value of the portfolio as a stochastic differential equation. A complete example of market model along with a calibration method is also given. In the second paper, written in collaboration with Bruno Rémillard, we propose a similar model with discrete time trading. We study the problem of derivatives pricing and give explicit formulas for European option prices. Specific conditions to rule out arbitrage are also provided. Using the dual optimization method, we show that the price of European options can be written as the optimization of an expectation over a set of probability measures. Chapter 5 contained the third paper and studies a different topic. In this paper, also written with Bruno Rémillard, we propose a forecasting method for time series based on multivariate copulas. To provide a better understanding of the proposed method, with the help of numerical experiments, we study the effect of the strength and the structure of the different dependencies on predictions performance. Since copulas allow to isolate the dependence structure and marginal distributions, we study the impact of different marginal distributions on predictions performance. Finally, we also study the effect of estimation errors on the predictions. In all the cases, we compare the performance of predictions by using predictions based on a bivariate series and predictions based on a univariate series, which allows to illustrate the advantage of the proposed method. For practical matters, we provide a complete example of application on financial data.

Les trois essais dans cette thèse étudient les implications des frictions financières, telles que les contraintes de collatérale ou de crédit, pour les décisions économiques des agents et leur impact sur les variables macro-économiques agrégées. Dans le premier chapitre "Financial Contracts and the Political Economy of Investor Protection" nous proposons une théorie du niveau de protection des investisseurs. Une faible protection des investisseurs implique un coût de financement externe plus élevé à cause des problèmes d'agence plus aigus entre les investisseurs et les entrepreneurs. À l'équilibre, ceci exclut les agents plus dépendants sur le financement externe de l'entrepreneuriat, ce qui augmente les profits des entrepreneurs qui restent actifs. Quand le niveau de la protection des investisseurs est choisi par un vote majoritaire, la théorie génère (i) une protection des investisseurs plus faible dans les économies avec plus grande inégalité dans les besoins de financement externe parmi les entrepreneurs, (ii) une dynamique non-monotone de l'output, (iii) améliorations (détériorations) de la protection des investisseurs suite à des ralentissements (accélérations) de l'output agrégé. L'évidence empirique donne un support à ces prédictions de la théorie. Dans le deuxième chapitre "Financial Frictions, Internal Capital Markets, and the Organization of Production", nous examinons comment la présence des frictions financières peut mener à la formation des conglomérats et des "business groups" diversifiées. Particulièrement, nous construisons un modèle d'équilibre général d'entrepreneuriat dans lequel les conglomérats émergent de façon endogène et substituent partiellement le marché du crédit imparfait. Nous montrons que ce modèle est capable d'expliquer quantitativement plusieurs faits stylisés concernant l'organisation de la production, les différences de productivité entre les firmes et les différences en présence des conglomérats entre les pays. Le troisième chapitre "Size and Productivity of Single-segment and Diversified Firms: Evidence from Canadian Manufacturing" étudie empiriquement la relation entre la taille, la productivité, et la structure organisationnelle d'une firme. Utilisant les micro-données sur les établissements manufacturiers canadiens, nous documentons plusieurs faits stylisés concernant la taille et la productivité totale des facteurs des établissements dans les conglomérats et dans les firmes non-diversifiées. Nous trouvons que les établissements dans les conglomérats sont en moyenne plus larges que leurs contreparties dans les firmes non-diversifiées, les petits établissements dans les conglomérats sont moins productifs que les établissements de taille similaire dans les firmes non-diversifiées, mais les larges établissements dans les conglomérats sont plus productifs que ceux de taille similaire dans les firmes non-diversifiées. Cette évidence est consistante avec réallocation interne efficiente des ressources au sein des conglomérats. / The three essays in this thesis study the implications of financial frictions, such as collateral and credit constraints, for economic decisions of agents and their impact on aggregate macroeconomic variables. In the first chapter "Financial Contracts and the Political Economy of Investor Protection", we propose a theory of the level of investor protection. Lower investor protection implies higher cost of external financing due to more severe agency problems between outside investors and entrepreneurs. In equilibrium, this excludes more financially dependent agents from entrepreneurship, increasing the profits of the remaining entrepreneurs. When the level of investor protection is chosen by majority voting, the theory generates (i) lower investor protection in economies with higher inequality in financial dependence across entrepreneurs, (ii) non-monotone output dynamics, (iii) improvements (worsening) of investor protection following output slowdowns (accelerations). The empirical evidence provides some support to these predictions. In the second chapter "Financial Frictions, Internal Capital Markets, and the Organization of Production", we investigate how the presence of financial frictions may lead to formation of diversified conglomerates or business groups. Specifically, we build a general equilibrium model of entrepreneurship in which business groups arise endogenously and partially substitute for imperfect credit market. We show that the model is able to quantitatively explain several key stylized facts on the way production is organized, on cross-firm productivity differences, and on cross-country differences in the degree of conglomeration. The third chapter "Size and Productivity of Single-segment and Diversified Firms: Evidence from Canadian Manufacturing" studies empirically the relation between size, productivity, and the organizational structure of a firm. Using micro-data on Canadian manufacturing plants, we document several stylized facts about size and total factor productivity of establishments in conglomerates and single-segment firms. We find that establishments in conglomerates are on average larger than their counterparts in single-segment firms, small plants in conglomerates are less productive than plants of similar size in single-segment firms, but large plants in conglomerates are more productive than those of similar size in single-segment firms. This evidence is consistent with efficient internal reallocation of resources in conglomerates.

Cette thèse examine les effets des imperfections des marchés financiers sur la macroéconomie. Plus particulièrement, elle se penche sur les conséquences de la faillite dans les contrats financiers dans une perspective d'équilibre général dynamique. Le premier papier construit un modèle qui utilise l'avantage comparatif des banques dans la gestion des situations de détresse financière pour expliquer le choix des firmes entre les prêts bancaires et les prêts du marché financier. Le modèle réussit à expliquer pourquoi les firmes plus petites préfèrent le financement bancaire et pourquoi les prêts bancaires sont plus répandus en Europe. Le premier fait est expliqué par le lien négatif entre la valeur nette de l'entreprise et la probabilité de faire faillite. Le deuxième fait s'explique par le coût fixe d'émission de bons plus élevé en Europe. Le deuxième papier examine l'interaction entre les contraintes de financement affectant les ménages et les firmes. Une interaction positive pourrait amplifier et augmenter la persistance de l'effet d'un choc agrégé sur l'économie. Je construis un nouveau modèle qui contient des primes de financement externes pour les firmes et les ménages. Dans le modèle de base avec prix et salaires flexibles, j'obtiens une faible interaction négative entre les coûts de financement des firmes et des ménages. Le facteur clé qui explique ce résultat est l'effet du changement contre cyclique du coût de financement des ménages sur leur offre de travail et leur demande de prêts. Dans une période d'expansion, cet effet augmente les taux d'intérêt, réduit l'investissement et augmente le coût de financement des entreprises. Le troisième papier ajoute les contraintes de financement des banques dans un modèle macroéconomiques avec des prêts hypothécaires et des fluctuations dans les prix de l'immobilier. Les banques dans le modèle ne peuvent pas complètement diversifier leurs prêts, ce qui génère un lien entre les risques de faillite des ménages et des banques. Il y a deux effets contraires des cycles économiques qui affectent la prime de financement externe de la banque. Premièrement, il y a un lien positif entre le risque de faillite des banques et des emprunteurs qui contribue à rendre le coût de financement externe des banques contre cyclique. Deuxiément, le lissage de la consommation par les ménages rend la proportion de financement externe des banques pro cyclique, ce qui tend à rendre le coût de financement bancaire pro cyclique. En combinant ces deux effets, le modèle peut reproduire des profits bancaires et des ratios d'endettement bancaires pro cycliques comme dans les données, mais pour des chocs non-financiers les frictions de financement bancaire dans le modèle n'ont pas un effet quantitativement significatif sur les principales variables agrégées comme la consommation ou l'investissement. / This Dissertation examines the effect of financial market imperfections on the Macroeconomy. More particularly, it focuses on the consequences of equilibrium default using a Dynamic General Equilibrium approach. The first paper builds a dynamic general equilibrium model that emphasizes banks' comparative advantage in monitoring financial distress in order to explain firms' choice between bank loans and market debt. Banks can deal with financial distress more cheaply than bond holders, but this requires a higher initial expenditure proportional to the loan size. In contrast, bond issues may involve a small fixed cost. Entrepreneurs' choice of bank or bond financing depends on their net worth. The model can explain why smaller firms tend to use more bank financing and why bank financing is more prevalent in Europe than in the US. The first fact can be explained by the negative link between the net worth of a business and its default probability. Explaining the second fact requires taking into account the higehr fixed cost of issuing market debt in Europe. The second paper examines the possibility of feedback effects between between the financing constraints of households and of firms. A positive interaction between the financial strength of household and firm balance sheets may amplify aggregate shocks and increase the persistence of aggregate fluctuations. I develop a new model that incorporates both firm and household external finance spreads and time varying leverage. Contrary to a common intuition, the baseline Real Business Cycle model with credit constraints produces a small negative interaction between the costs of external financing for firms and households. The key factor in this result is the effect of changes in the external finance premium on borrowers' labour supply and the demand for loans. The reduction in households' cost of borrowing in a boom decreases labour supply and raises houshold loan demand. This increases interest rates, crowds out investment, and raises borrowing costs for financially constrained firms. The third paper integrates household financing frictions with bank financing frictions and house price fluctuations in a dynamic general equilibrium model. The key assumption in the model is that a bank cannot fully diversify shocks, leading to a link between household and bank sectors' default risks. The cyclical behaviour of banks' external funding cost is determined by two main factors. On one hand, booms improve the financial health of the banks' borrowers which tends to reduce the cost of bank funding. On the other hand, consumption smoothing by savers and borrowers during booms increases the proportion of external financing in the banks' balance sheet which tends to increase the cost of bank funding. As a result of these opposing effects, the model matches procyclical profits and leverage in the financial sector, as observed in the data, but for non financial shocks the banking frictions in the model have an insignificant impact on the main macroeconomic aggregates such as output, consumption and investment.

La décentralisation implantée en 2004 au Niger, a pour objectif de promouvoir le développement « par le bas » et de diffuser les principes démocratiques dans les milieux locaux, afin d’améliorer les conditions de vie des populations. Les recherches sur le sujet font état d’un écart considérable entre les objectifs et les réalisations de la décentralisation. Les facteurs avancés pour expliquer cet écart sont entre autres, le faible appui technique et financier de l’État envers les collectivités territoriales ou encore la quasi-inexistence d’une fonction publique locale qualifiée et apte à prendre en charge les projets de décentralisation. Toutefois, ces observations s’avèrent insuffisantes pour rendre compte des difficultés rencontrées par les acteurs de la décentralisation au Niger. Nous affirmons que les partis politiques jouent un rôle fondamental dans le processus de décentralisations. Ceux-ci diffusent des stratégies d’influence politique et de patronage dans les arènes locales. Les stratégies des partis politiques entravent les initiatives des acteurs locaux, notamment leur capacité de mobilisation des ressources financières. / Decentralization began in 2004 in Niger, aims to promote development "from below" and spreading democratic principles in local communities, in order to improve the living conditions of populations. Research available shows a considerable gap between goals and achievements of decentralization. Factors presented by researchers to explain this difference are the weak technical and financial support of the State toward local authorities, or the quasi-absence of a qualified local civil service, able to support decentralization projects. However, these arguments are insufficient to explain the difficulties encountered by decentralization actors. Thus, I argue that political parties play a key role in the decentralization process. They disseminate political influence strategies and patronage practices in local arenas. Therefore, their strategies hinder local actors’ actions, especially their ability to mobilize financial resources.
