The dissertation is a compilation of three essays on Turkey's poverty alleviation programs. The first paper focuses on the welfare impact of the global financial Crisis on Turkish households. The second paper considers the protective impact of the Green Card non-contributory health insurance program in Turkey during the Crisis in 2008-2009. The third paper uses experimental data from the field in eastern Turkey, to look at patterns of agricultural technology diffusion in a rural development program implemented in a post-conflict setting.

The impacts of tropical deforestation and forest degradation are felt at multiple levels, bringing about local ecosystem degradation, regional biome fragmentation and global contributions of 12-15% of anthropogenic greenhouse gas emissions. In response to this, markets and payments for ecosystem services have emerged to financially value the services forests provide, most notably in the form of mechanisms to reduce deforestation and enhance forest conservation (REDD+). REDD+ has received much attention at the international level, but the pressing contemporary challenge is its engagement at the local scale. This thesis examines the potential local-level engagement of REDD+ on the Amazon frontier as an approach to altering patterns of anthropogenic encroachment on the world's greatest expanse of tropical forest. Case studies are taken from the buffer zones of protected areas along Peru's Amazonian frontier, Yanachaga-Chemillen National Park (YChNP) in central Peru and Manu National Park (MNP) in the SE of the country. A political ecology approach is taken to examine the influences and implications of existing land use governance structures, local livelihoods and preferences, and smallholder production and land economy, in the context of REDD+. Adopting mixed methods comprising semi-structured interviewing and land user surveys, data were collected between July 2008 and September 2009. I show that the two sites' histories and geographies have shaped distinct challenges for REDD+. The proximity of YChNP to Lima has fuelled agricultural expansion and higher land use incomes, yet institutions – particularly those belonging to the state – are exceedingly weak. The pace of land use change here obliges certain urgency for REDD+ interventions to provide livelihood alternatives, divert the current development path and restore the landscape. MNP’s rurality has protected it to date from expansive deforestation, yet weak institutions, poverty and increasing threats from national development processes highlight the importance of REDD+ interventions. In an analysis of land economy, an innovative conceptual framework is presented, the '3Rs' (rewarding, regulating and reshaping) to tackle local heterogeneity in REDD+ engagement. This thesis contributes knowledge to the practical and theoretical advancement of REDD+, and proposes the mechanism as an important new arena for academic investigation.

This thesis is an investigation into the microeconomic mechanisms that govern some of the occupational choices faced by workers in Sub-Saharan Africa, and into the monetary and non-monetary returns to their decisions. Chapter 1 begins by exploring the decision process that leads workers to allocate themselves to different occupations within the economy. In particular, I investigate the role of risk-aversion in the allocation of workers between formal and informal jobs in Ghana, hence attempting to explain a fundamental dimension of duality through an investigation into workers' preferences. In my model of sectoral allocation risk-averse workers can opt between entering the free-entry informal sector and queuing for formal occupations. Conditional on identifying the riskier option, the model yields testable implications on the relationship between risk-aversion and workers' allocation. My testing strategy proceeds in two steps. First, using the first three waves of the Ghana Household Urban Panel Survey (GHUPS) dataset, I estimate expected income uncertainty and find it considerably higher in the informal sector than in formal employment. Second, using experimental data to elicit risk-attitudes I estimate the effect of risk-aversion on occupational choices and I find that, in line with the first result, more risk-averse workers are more likely to queue for formal jobs and less likely to be in the informal sector. The conclusion of the first chapter is that attitudes to risk should feature more prominently in models of sector allocation and in the design of labour market policies, in particular when those policies aim to impact workers' vulnerability to risk and uncertainty. Chapter 2 focuses on the largest occupational category in the Developing world, self-employed workers with small productive activities, and it tries to estimate the returns to different productive assets, namely physical capital, labour and human capital. These are the workers that form most of the informal sector analysed in chapter 1, which allows me to draw a direct link with the analysis so far. The chapter begins by specifying a model for the income-generating process grounded in the literature on firms' production and hence abridging the gap between the analysis of individual earnings and the study of firms' value added. Identification in the empirics is achieved by means of panel estimators that are suitable to address the endogeneity of input choices, which derives from both time-varying and time-invariant unobservable heterogeneity. The use of these estimators is made feasible by the length of the Ghanaian Household Urban Panel Survey dataset at CSAE. I also explore issues of endogeneity in the selection of different technologies, defined by their relative capital and labour intensity. Finally, I analyse the shape of returns to capital, with the aim to detect potential non-convexities in technology. The results show that capital and work-experience play the strongest role in income-generation, while the shares of value added attributed to labour and to formal schooling are low. Marginal returns to investment are high at low capital levels and they decrease very rapidly, pointing against the existence of non-convexities due to minimum scale requirements, but implying that real income gains resulting form micro-investment are modest. Chapter 3 returns to the issue of earnings uncertainty and risk-aversion explored in Chapter 1, but it now takes the allocation choice as given and explores the direct welfare implications of income uncertainty for worker's well-being. Namely, the chapter explores the relationship between income and welfare, with a particular attention on the link between income vulnerability and happiness. Using unique longitudinal data on life-satisfaction and labour market outcomes, I estimate an individual measure of vulnerability (defined as the probability of falling below a low-income threshold) and investigate its effect on well-being. After controlling for unobservable individual fixed effects, work-satisfaction, relative income and other relevant worker characteristics, I find a sizable impact of vulnerability, over and above the income effect. When I explore the mechanisms behind my results, I find that aspiration adaptation to current income may result in a transitory income effect. Moreover, using my direct measure of attitudes to risk from field-experiments (already used in chapter 1), I can test directly the hypothesis that more risk-averse agents suffer more heavily from a given increase in income vulnerability. Overall, my findings support policy interventions that aim to reduce vulnerability, as I expect such policies to have a 'direct' impact on agents' happiness given the prevailing attitudes to risk and uncertainty in the population. Finally, from the point of view of overall social welfare, my results suggest that non-Rawlsian growth models, whereby 'someone may be left behind', may fail to enhance general welfare, for high enough levels of risk-aversion in the population, if the risk of falling behind is sufficiently widespread.

Cette thèse s'inscrit dans le cadre de l'économie de développement, et tente de traiter la question de blocage économique dans la région arabe, une situation qui a longtemps marqué cette zone. Nous proposons une nouvelle carde d'analyse qui adopte la notion de l'économie fondée sur la connaissance (EFC), qui a été élaboré par la Banque Mondiale, dans laquelle cette économie est composée de quatre piliers, a savoir : incitation économique et régime institutionnel, éducation et ressources humaines, Système d'innovation et l'infrastructure d'information (TIC). La thèse emploie le concept de l'EFC afin d'inspecter, d'analyser et d'évaluer la situation économiques dans les pays arabes depuis l'indépendance et jusque la veille des révolutions arabes, nommé : le printemps arabe. A travers de cette thèse nous élaborons plusieurs types d'analyse, et à la fin de thèse nous proposons un modèle économétrique permettant l'évaluation de la contribution de la connaissance à la croissance et au développement dans ces pays. / This thesis is part of the economics of development. It addresses the issue of the economic morass in which the Arab region has been mired for decades. We suggest a new analytical framework that builds upon the concept of knowledge-based economies and its four pillars – economic incentive and institutional regime, education and human resources, innovation system, and, finally, information infrastructure (ICT) - as conceived by the World Bank. Our thesis mobilizes this concept of knowledge-based economies in order to analyze and evaluate the state of the economy in the Arab region from the independence period to the eve of the revolution in Arab countries ' Arab spring'. Throughout the thesis, we develop several types of analysis and we conclude with an econometric model, that assesses the contribution of knowledge to growth and development in the Arab region.

L’objet de cette thèse est d’analyser l’évolution du système de vulgarisation agricole en contexte méditerranéen, en termes d’organisation, de dimensions du conseil et de méthodes d’intervention à partir d’une analyse régionale des systèmes syrien et tunisien. Cette évolution répond à des changements profonds du modèle de production agricole, basé historiquement sur les principes de la Révolution verte, qui s’oriente vers des modèles agro-écologiques. Nous nous situons dans le mouvement dit de la « transition agroécologique », qui propose un cadre de développement associant les dimensions socioéconomiques et environnementales. Elle permet d'envisager une meilleure intégration de l'agriculture et de ses enjeux dans le projet de développement territorial. Concevoir et mettre en œuvre cette approche nécessite de changer profondément la gestion des systèmes de production. Pour assurer ces changements, les agriculteurs ont besoin de nouveaux dispositifs d’accompagnement. L’analyse de l’évolution des systèmes de vulgarisation est conduite à partir d’un cadre théorique et méthodologique construit en référence aux théories du développement, notamment évolutionniste, pour tenir compte des forces générales qui déterminent les actions locales, et historiciste, pour donner place aux trajectoires de développement et aux combinaisons territoriales singulières. Ce cadre suppose que le développement ne dépend pas de producteurs prêts à adopter des innovations exogènes mais plutôt à participer à son élaboration. Cette participation répond à deux besoins : i) l’adaptation de l’innovation à la particularité des situations comme la transition agroécologique le préconise, ii) la décentralisation de la gestion des biens socio-environnementaux, vers des formes de communs. Face à ces enjeux de transformation des systèmes agricoles, on peut s’attendre à ce que l’organisation de la vulgarisation agricole s’est adaptée par le passage d’un système piloté principalement par un dispositif public, basé sur une seule dimension de conseil technique et sur des méthodes diffusionnistes de vulgarisation de masse, à un système composite proposant plusieurs dimensions de conseil et de méthodes d’intervention individuelles ou communes basées sur la co-construction du conseil. L’analyse est conduite en prenant appui sur un travail empirique adapté à la situation des deux pays d’étude, circonscrit sur la région d’Al Ghâb en Syrie et de Nabeul en Tunisie. Les résultats sont assez proches dans les deux pays où l’évolution du secteur agricole se réalise par petites touches qui tiennent plus de la substitution de pratiques plus économes et plus respectueuses du milieu que les précédentes, mais elle n’a pas été accompagnée par une évolution marquante du système de vulgarisation agricole. Le dispositif étatique occupe toujours une position de monopole en Al Ghâb, et dominante à Nabeul. L’évolution organisationnelle de ce système se borne, dans les deux régions, à la déconcentration des services, avec une timide privatisation sur le terrain de Nabeul. Dans les deux régions d’études, le dispositif étatique utilise classiquement des méthodes collectives de conseil basées sur le modèle « Training and Visit » et se limite à une dimension technique basée principalement sur les recettes de la Révolution verte ; leur contribution à l’évolution des pratiques agricoles vers l’agroécologie n’est pas notable. / The aim of this dissertation is to analyze the evolution of the agricultural extension system in a Mediterranean context, in terms of organization, types of advice and methods of intervention drawn from a regional analysis of Syrian and Tunisian systems. This evolution responds to profound changes in the agricultural production model, historically based on the principles of the Green Revolution, which is evolving towards agro-ecological models. We situate this work in the movement known as the "agro-ecological transition", which proposes a framework of development associating socio-economic and environmental dimensions. This movement allows us to envision a better integration of agriculture and its stakes in the territorial development project. To design and implement the agro-ecological approach requires a profound change in the management of production systems. To ensure these changes, farmers need new support schemes. The analysis of the evolution of the extension systems is conducted from a theoretical and methodological framework constructed with reference to development theories, notably especially evolutionist, which take into account the general forces that determine local actions, and historicist, which give pace to development trajectories and singular territorial combinations. This framework assumes that the development does not depend on producers willing to adopt exogenous innovations but rather to participate in its elaboration. This participation meets two needs: i) the adaptation of innovation to the particularity of situations as the agroecological transition advocates ii) the decentralization of the management of socio-environmental goods, towards common forms. To deal with these challenges of transforming agricultural systems, we can be expected that the organization of agricultural extension has adapted by the passage of a system driven primarily by a public device, based on a single type of technical advice and on diffusionist methods of mass of extension, to a composite system offering several types of advice and individual or joint intervention methods based on the co-construction of the advice. Our analysis is based on an empirical work adapted to the situation of the two countries under study, circumscribed to the regions of Al Ghâb in Syria and Nabeul in Tunisia. The results are quite similar in both countries where the evolution of the agricultural sector occurs through small changes that rely more on the substitution of practices more economical and more respectful of the environment than previous practices, but these changes have not been accompanied by a significant evolution of the agricultural extension system. The state apparatus still occupies a monopoly position in Al Ghâb, and dominant in Nabeul. The organizational evolution of this system is limited, in both regions, to the deconcentration of services, with a timid privatization on the site of Nabeul. In both regions of study, the state apparatus uses classically collective counseling methods of advice based on the "Training and Visit" model, and is limited to a technical dimension based mainly on the proceeds of the Green Revolution, their contribution to the evolution of agricultural practices towards agroecology is not notable.

Cette dissertation aborde le concept mondialisation comme résultat d'une compétition politique, à travers une analyse des sources et conséquences de conflit, tout en mettant en lumière sa dimension socio-culturelle. Dans le cadre thématique de l'économie politique et de l'économie du développement, nous adressons un large éventail de sujets qui sont actuellement au centre du débat public. En particulier, j'explore les liens entre migrations et attitudes, aide et conflit, ainsi que les conséquences intergénérationnelles des conflits dans le développement économique. Je traite ces sujets de façon théorique et empirique, en utilisant un grand nombre de stratégies économétriques. La composante empirique de cette dissertation comprend une analyse de la migration et de la proximité culturelle sur plusieurs pays; une analyse à l'échelon sous-national de l'aide Chinoise en Afrique, et une analyse sur les conséquences de la guerre en Irak au niveau des ménages. / This dissertation sheds light on the concept of globalization as a result of political competition, analyzing the sources and consequences of conflict, as well as highlighting the socio-cultural dimensions of globalization. Under the thematic umbrella of political economics and economic development, I address a broad range of topics that have been at the center of the public debate in recent years. ln particular, I explore the links between migration and culture, attitudes, aid and conflict, and the inter-generational consequences of conflict for economic development. I address these subjects both theoretically and empirically, using a broad set econometric strategies. The empirical component of this dissertation comprises a global cross-country analysis of migration and cultural proximity, a sub-national analysis on Chinese aid in Africa, and a household-level analysis on the consequences of war in Iraq.

This thesis investigates three important themes within the development economics literature that link children, women and economic development. In the first essay we present an analysis of child labour among agricultural households in rural Nepal. We first examine the monetary contribution of child labour to family farms. For this purpose, within a non-separable agricultural household model we estimate a farm production function to obtain shadow wages for both children and adults employed on the farm. Our results reveal that the relative contribution of child labour to family income is not negligible. We then analyse child labour supply to explore whether it is driven by poverty or other reasons such as imperfections in the labour market. We estimate both a reduced form model and a structural equation model. This latter includes the estimated shadow wages and income from the previous analysis. Both models allow for an examination of how child labour supply reacts to a change in the opportunity cost of time and wealth. The reduced form results suggest that an increase in household's wealth (measured by land endowments) reduces child labour, specifically of girls. This result is consistent with the hypothesis of poverty-induced child labour in the presence of perfect labour markets. This decline, however, occurs for sufficiently high levels of wealth. Imperfections in the labour market may play a role in explaining child labour of boys and in households that are not at the top-end of the land distribution. Estimates of the structural labour supply model, however, yield results on wage and income elasticities that partly contradicts the theoretical predictions. In the second essay we analyse whether and how an increase in the participation of women in a key decision making body of local collective action institutions - the Executive Committee (EC) of Community Forest User Groups (CFUG) in Nepal - aspects forest protection, specifically household firewood collection. In many developing countries women are responsible for the collection and management of forest products essential to the daily lives of their household. Therefore they have stronger interests than men in ensuring the availability of these products. Despite this, women are often excluded from the decision-making process that sets out the rules to access and collect forest products within community forests. We account for the potential endogeneity of female participation and exploit an amendment made to the guidelines for CFUG formation that sets a higher threshold for women representation in the Executive Committee to evaluate the impact of women on firewood extraction. The results indicate that higher female participation in the ECs of CFUGs leads to a decrease in firewood extraction. This evidence is suggestive that women are prioritising conservation to ensure sustainable firewood extraction for their daily needs. In the third essay we analyse the short and long-term impact of violence on education in Timor Leste. Specifically, we examine the effect of the 1999 violence on school attendance in 2001 and its longer-term impact on primary school completion of the same cohorts of children observed again in 2007. We compare the educational impact of the 1999 violence with the impact of other periods of high-intensity violence during the 25 years of Indonesian occupation. The short-term effects of the conflict are mixed. In the longer term, we find evidence of a substantial loss of human capital among boys in Timor Leste exposed to peaks of violence during the 25-year long conflict. The evidence suggests that this result may be due to household trade-offs between education and economic welfare.

A number of developing countries have been on a quest to attract foreign direct investment (FDI) with the intention of increasing capital inflow through technological spillovers and transfer of managerial skills. FDI can increase economic growth and development of a country by creating employment, and by doing so, increasing economic activity that will lead to economic growth. South Africa is one of the economies that strive to attract more FDI inflows into the country to be able to improve its economy, and the country has adopted policies that drive the motive to attract FDI inflows. This study investigated the effect of FDI on sectoral growth over the period 1970–2014. The purpose was to find out where in the three key sectors of South Africa FDI is more significant. The review of theoretical and empirical literature on FDI revealed that FDI has a diverse effect on economic growth, both in developed and developing countries. Theoretical literature analysed the behaviour of multinational firms and the motive behind multinationals investing in foreign countries. According to Dunning (1993), firms have four motives to decide to produce abroad, namely natural resource-seeking, market-seeking, efficiency-seeking and strategic asset-seeking. Empirical studies on sectors show that FDI inflows affect different sectors in different ways, and that the agricultural sector does not usually gain from FDI inflows, whereas subsectors in the industry and services sector grow from receiving FDI inflows. Sectoral analysis revealed that the services sector receives more FDI inflows, when compared to the agriculture and industry sector. The study followed an econometric analysis technique to test the effect of FDI inflows on the agriculture, industry and services sectors. The augmented Dickey–Fuller and Phillips–Perron tests were used to test for unit root. Both tests revealed that variables were not stationary at level, but that they become stationary at first difference. Vector autoregressive (VAR) models were estimated, and four types of diagnostic tests were performed on them to check the fitness of the models. The tests showed that residuals of the estimated VARs were robust and well behaved. The Johansen cointegration test suggested there is cointegration and that there is a long-run relationship between variables. Following the existence of cointegration, the estimated Vector error correction model (VECM) results showed that FDI has a significant effect on the services and industry sector, but has a negative effect on the agricultural sector. Impulse response analysis results revealed the correct signs, and confirmed the VECM results. FDI inflows explain a small percentage of growth in agriculture and industry, but a sizable and significant percentage in the services sector. / Economics / M. Com. (Economics)

New technology and new innovations have for long been considered as a spring for growth. Conservation farming (CF) is a new production method introduced in rural Zambia and previous research shows that it increases yields and improves soil fertility. Even though the method is proven more efficient than conventional agriculture, only approximately 10 % of Zambia’s farmers have adopted the method. The purpose of this study is to discuss the implications of the introduction of CF on the capabilities of farmers and on economic growth. Furthermore, the study aims to explore why CF, which is proven to be more economically efficient than the conventional method, is not adopted to a larger extent in Zambia. A qualitative study of 25 farmers, farming with either CF or conventional methods, was performed in the region of Mumbwa, Zambia. The results were divided depending on whether the farmers were using the new method or not. To analyze the selected material theories were chosen that regard economic growth and technological change, the adoption process of new innovations, incentive creation and the expansion of capabilities. The two groups showed differences in age, the size of their land, how many crops they grew and to what extent they were working for others or hiring labor. The conclusion from the small sample of farmers is that the farmers using CF had been able to expand their capabilities in different ways. They had food for all the year, the new method allowed them to plan their time better and it was more environmentally sustainable than the old method. The negative aspect of CF is that it is not compatible with the old method in terms of social norms. CF leads to a more efficient use of capital and labor and therefore it can increase the economic growth. In terms of a new innovation, CF seems to have a relative advantage over the old method but it must be spread to a larger group of farmers to reach a breakthrough. To create a higher adoption rate of the method the farmers’ perception must be taken into account. / Minor Field Study (Sida)

In this study an analysis of the long-term equilibrium relationship between economic growth measured as real GDP growth and private capital inflows is explored. The link between private capital inflows and economic growth is well-documented in the literature. However, a void in the literature relates to examining the cointegrating relationship between private capital inflows and economic growth particularly for South Africa. It is widely claimed that private capital inflows foster economic growth by closing the savings/investment gap. However, clarity on this point is necessary because of the seemingly unclear nature of the relationship in the literature. The exact form of this relationship as well as the nature of capital flows that could impact on real growth requires further investigation. Moreover, what exactly happens to this relationship in an economic crisis such as recently recorded in the global financial crisis is not clear. The analysis is undertaken by employing cointegration and vector error correction modeling approach using quarterly data for the period 1989q4-2009q4. This study employs the Johansen (1998) cointegration test. This technique distinguishes itself since it establishes the long run relationship between variables. Thereafter, residual diagnostic checks are performed on the variables. Our results show among others, that private capital inflows have impacted positively on the growth of the South African economy. The areas for further research that emerge from this study include the effect of some government policies on economic growth that should also receive more attention in the future since political instability slows down investment.
