Testing saving and investment rates to understand capital mobility and current account solvencyHerzog, Ryan William, 1981- 12 1900 (has links)
xiii, 160 p. : ill. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number. / Feldstein and Horioka (1980) motivated the international finance literature by claiming a least squares regression of domestic investment rates on domestic savings rates is an informative measure of capital mobility. Their method stirred up controversy when they interpreted a high correlation between savings and investment rates as evidence of capital immobility, creating the famous Feldstein-Horioka puzzle. Current research starts with the Feldstein-Horioka result and shifts focus toward measuring short and long-run adjustments to external imbalances. The literature has implemented dynamic time-series and panel estimators to test the relationship. Following recent literature, each chapter in this dissertation jointly focuses on the adjustment process of current account imbalances and the conditions required for capital mobility.
The intent of this study is to show through the use of new estimation techniques previous results have been largely misguided. The starting point for this analysis is a thorough review of three key equations used in saving-investment regressions. The three models in question are an ordinary least squares model, error correction model, and an autoregressive distributive lag estimator. Each model is tested for stability, and it is found that a number of countries have an unstable relationship. One argument for the instability results is the presence of structural breaks. Previous literature has found that both variables follow non-stationary processes, but when using more powerful unit root tests and controlling for level shifts, both variables appear stationary. If each variable is stationary then previous methods assuming non-stationarity will produce incorrect inferences. Each series is optimally estimated for structural breaks, and through a mean differencing process the savings-investment coefficient is significantly reduced. Additionally, removing the exogenous breaks and using the lower frequency components allows for modeling the short-run current account adjustment process. Finally, the results are extended to measure the relationship in a panel framework using dynamic panel estimators and threshold effects. After controlling for structural breaks the coefficient decreases and exhibits a downward trend. The remaining correlation can be explained through trade openness and country size measures. / Committee: Nicolas Magud, Chairperson, Economics; Stephen Haynes, Member, Economics; Jeremy Piger, Member, Economics; Regina Baker, Outside Member, Political Science

Croissance par l'innovation et emploi dans les pays du Sud de la Méditerranée " une application à l'emploi des jeunes" / Growth through innovation and employment in the Southern Mediterranean countries : "An application to youth employment"Gaysset, Isabelle 09 November 2015 (has links)
Les pays de la région Mena ont un point commun, la recrudescence du chômage de masse des jeunes diplômés. Ce problème lié à la dynamique et à la qualité de la croissance, à une carence chronique en démocratie, cause des déséquilibres socio-économiques qui menacent la stabilité et le développement dans la région. Les PM doivent transformer leur modèle de croissance actuel peu différencié, en un modèle à productivité globale des facteurs, où l’innovation améliore de façon continue la qualité et la combinaison des facteurs et permet d’emprunter un régime de croissance endogène fondé sur le progrès technologique. Après une introduction générale, le chapitre II présente les systèmes d’innovation des PM et leurs effets sur l’emploi dans une analyse en composantes principales, et une étude en panel des déterminants de la croissance. Dans les chapitres III et IV, les effets de l'économie de la connaissance sur l'emploi des jeunes sont soigneusement étudiés par une analyse en séries chronologiques en panel pour la région MENA, d'une part, et pour l’étude du cas tunisien, de l'autre. Le chapitre V donne les principales conclusions de l’étude. / Countries in the MENA region have been recently characterized by a common feature mainly the upsurge in the unemployment of young graduates. This is due to the dynamics and quality of economic growth, a chronic democracy deficiency, and socio-economic imbalances that threaten the stability and development wihtin the region. The PM must alter their current growth framework into a total factor productivity model, whereby innovation continuously improves, allowing for an endogenous growth regime based on technology progress to take over. After a general introduction, Chapter (II) highlightst the PM’s innovation systems and their effects on employment generation in a principal component analysis, and a panel study of the determinants of economic growth. In chapter (III) and (IV), the effects of the knowledge economy on youth employment are carefully studied though a time series analysis for the MENA region as a panel on one hand and for Tunisia a single case study on the other. Chapter (V) gives the mains conclusions of the study

Essays on Economic Growth, Firm Productivity, Household Labor Supply and WelfareAcquah, Esther 01 February 2024 (has links)
This dissertation is in three distinct chapters, although not entirely independent. The various chapters present empirical evidence in economic growth and development using data at the country, firm, and household-community levels. Over the years, the United Nations Sustainable Development Goals have given rise to copious theoretical and empirical research. This thesis moves in line with these studies. Specifically, contributing to the subject of ensuring access to affordable, reliable, sustainable, and modern energy for all (SDG 7), provision of full and productive employment and sustained economic growth (SDG 8), availability of financial services and markets (SDG 9), and building sustained development and inclusive institutions (SDG 16). The thesis uses data from various sources at different levels--country, firm, and household--to test important growth and development issues that are considered gray areas that require extensive research. The first chapter is dedicated to investigating the relationship between economic institutions and growth. While the importance of institutions in fostering economic growth and development has not been disputed, there is now a developing literature on the nonlinearity between growth and institutions. This paper examines the existence of nonlinearities between economic institutions and growth and, particularly, the presence of threshold effects for a sample of advanced and developing countries. Using political institutions to instrument economic institutions in a dynamic panel threshold model, the results reveal the existence of institutional-threshold effects in a first difference generalized method of moments (FD-GMM) approach. Specifically, for economic institutions to affect growth, they must on average develop to at least 6 and 8 (out of a score of 10) for developing and advanced economies, respectively. Both the short-run and long-run effects of economic institutions on growth are positive and only significant for developing countries. The results show the primacy of sub-indices of economic institutions such as freedom to trade internationally, legal structures, and property rights for economic growth. Next, I narrow things down to the firm level. The second chapter of this thesis is devoted to searching for transmission channels from finance to firms' productivity and growth in the developing countries context. There is a consensus among economists that financial development fosters economic growth. Among other things, the productivity effect of access to finance by firms is considered one of the important channels through which finance affects growth. This paper empirically investigates the relevance of this channel using firm-level data from the World Bank Enterprise Survey for several developing countries from 2002 to 2020. The results indicate that access to finance is generally limited, although larger firms have better access to finance irrespective of their age. Holding all other factors constant, improved access to finance significantly increases the productivity of young and small-sized firms while reducing their growth in employment. Also, compared to matured and medium-sized but financially constrained firms, the results show that enhanced access to finance significantly boosts the employment growth of old (but small) firms. Lastly, the results show different sources of financing (external, formal, and informal) have varied effects on firms’ growth and productivity. From the results, a long-term growth policy package recommended should therefore include special financing schemes that improve access to finance for young and small firms. In the third chapter, I study the labor supply and welfare benefits of electrification. The share of a country’s population with access to electricity is a good indicator of its growth and development since it has important labor and welfare implications. This paper estimates the causal effect of access to electricity on development outcomes such as employment, wages, and hours of work, as well as the reallocation of labor across the agriculture and non-agricultural sectors in Ghana. First, I demonstrate that topography matters in grid expansion, especially in rural Ghana, using the three most recent waves of the Ghana Living Standard Survey (rounds 5, 6, and 7). I do this by using the slope of the land as an instrumental variable IV. Second, the IV estimates show no significant improvement in general employment and wages, whilst inducing shifts in employment from agriculture to the non-agriculture sectors because of electricity. Also, hours of work increase, especially for those in the non-agriculture sector. An important mechanism through which electrification affects labor and welfare outcomes in Ghana is the increase in underground economic activities.

Croissance, effet et attractivité des investissements directs étrangers : le rôle des institutions / Growth, effect and attractiveness of FDI : the role of institutionsTrojette, Inès 07 December 2016 (has links)
La présente thèse a pour objectif d'analyser le rôle des institutions sur la croissance économique, et notamment sur l'attractivité et l'effet des investissements directs étrangers (IDE). Pour cela, nous avons utilisé douze indicateurs de mesure de la qualité des institutions et testé leurs effets en retenant un échantillon important de pays développés, en voie de développement et en transition. Notre démarche se décline en trois chapitres. Le chapitre 1 est consacré à l'évaluation de l'effet direct des institutions sur la croissance économique en fonction du niveau de développement des pays étudiés. Les résultats montrent que la qualité des institutions a un effet plus important sur la croissance dans les pays à revenu intermédiaire, en particulier la stabilité politique et la lutte contre la corruption. Pour les pays à revenu élevé le facteur le plus déterminant est le respect des lois et des contrats. Le chapitre 2 analyse l'effet indirect des institutions sur la croissance à travers les IDE. Les résultats mettent en évidence l'existence des seuils institutionnels qui conditionnent l'effet des IDE sur la croissance selon la situation géographique et le niveau de développement des pays. Il ressort notamment que la lutte contre la corruption et l'amélioration de la démocratie sont les canaux travers lesquels les IDE favorisent la croissance dans les pays d'Afrique du Nord et du Moyen-Orient et d'Asie, la stabilité d gouvernement et le respect des contrats étant les plus importants dans les pays d'Europe et d'Amérique. Le chapitre 3 s'intéresse à l'effet de l'ouverture financière et du développement financier sur l'attractivité des IDE en mettant e évidence le rôle des institutions. Les résultats montrent que pour les pays qui ont libéralisé leur compte de capital, l'entrée d'IDE est plus importante lorsqu'ils disposent d'une bonne qualité institutionnelle. De la même manière, l'attractivité des IDE est favorisée par 1 passif liquide des banques et les crédits au secteur privé, mais il est moindre pour les pays dotés d'importantes ressources naturelle: Les résultats soulignent l'existence d'un seuil institutionnel à partir duquel le poids de la capitalisation boursière et des litres échangé en bourse favorisent l'attractivité des IDE. La confrontation des résultats des chapitres 2 et 3 permet d'avancer que le seuil institutionnel à travers lequel le développement financier améliore l'attractivité des IDE est plus élevé que le seuil à travers lequel les IDE impactent la croissance. Dans les pays e développement en particulier, la qualité des institutions constitue une contrainte plus sévère en termes d'attractivité qu'en termes d'effet des IDE sur la croissance. / This thesis aims to investigate the role of institutions on economic growth, specifically through the attractiveness and the impact of Foreign Direct lnvestment. For this, we use twelve measures of the institutional quality and we test their effects using a set of developed, developing and transition countries. Our approach is divided into three parts. Chapter 1 analyzes the direct effect of institutions on economic growth by level of development of countries. Results show that the quality of institutions has a greater effect on growth in middle-income countries, particularly the effects of political stability and fightinç against corruption. For high-income countries, the most important factors are respect of laws and contracts. Chapter 2 examines the indirect effect of institutions on growth through FDI. Results highlight the existence of institutional thresholds that condition the effect of FDI on economic growth by countries and by level of incarne. It appears that fighting against corruption an improving democracy are the mechanisms through which FDI promotes growth in the MENA and the Asia group, and through the respect of contracts and government stability in the Europe and the America group. Chapter 3 assesses the effect of financial openness and financial development on the attractiveness of FDI by highlighting the role o institutions. Results indicate that countries that have opened their capital account have received more FDI inflows and the effect is higher in countries with good institutional quality. Similarly, FDI attractiveness is enhanced by liquid liabilities and credit to the private sector but is lower in natural resouce endowed countries. The results highlight that countries are able to attract FDI through stock market capitalization and traded only above an institutional threshold. We highlight in this thesis that the institutional level through which financial development impact the attractiveness of FDI is higher than the institutional level through which FDI contributes to growth. ln the developing group, the quality of institutions is an important constraint in term of attractiveness than in terms of the effect of FDI on GDP growth.

Predictions of Effective Models in Neutrino PhysicsBergström, Johannes January 2011 (has links)
Experiments on neutrino oscillations have confirmed that neutrinos have small, but non-zero masses, and that the interacting neutrino states do not have definite masses, but are mixtures of such states.The seesaw models make up a group of popular models describing the small neutrino masses and the corresponding mixing.In these models, new, heavy fields are introduced and the neutrino masses are suppressed by the ratio between the electroweak scale and the large masses of the new fields. Usually, the new fields introduced have masses far above the electroweak scale, outside the reach of any foreseeable experiments, making these versions of seesaw models essentially untestable. However, there are also so-called low-scale seesaw models, where the new particles have masses above the electroweak scale, but within the reach of future experiments, such as the LHC.In quantum field theories, quantum corrections generally introduce an energy-scale dependence on all their parameters, described by the renormalization group equations. In this thesis, the energy-scale dependence of the neutrino parameters in two low-scale seesaw models, the low-scale type I and inverse seesaw models, are considered. Also, the question of whether the neutrinos are Majorana particles, \ie , their own antiparticles, has not been decided experimentally. Future experiments on neutrinoless double beta decay could confirm the Majorana nature of neutrinos. However, there could also be additional contributions to the decay, which are not directly related to neutrino masses. We have investigated the possible future bounds on the strength of such additional contributions to neutrinoless double beta decay, depending on the outcome of ongoing and planned experiments related to neutrino masses. / QC 20110812

Models in Neutrino Physics : Numerical and Statistical StudiesBergström, Johannes January 2013 (has links)
The standard model of particle physics can excellently describe the vast majorityof data of particle physics experiments. However, in its simplest form, it cannot account for the fact that the neutrinos are massive particles and lepton flavorsmixed, as required by the observation of neutrino oscillations. Hence, the standardmodel must be extended in order to account for these observations, opening up thepossibility to explore new and interesting physical phenomena. There are numerous models proposed to accommodate massive neutrinos. Thesimplest of these are able to describe the observations using only a small numberof effective parameters. Furthermore, neutrinos are the only known existing particleswhich have the potential of being their own antiparticles, a possibility that isactively being investigated through experiments on neutrinoless double beta decay.In this thesis, we analyse these simple models using Bayesian inference and constraintsfrom neutrino-related experiments, and we also investigate the potential offuture experiments on neutrinoless double beta decay to probe other kinds of newphysics. In addition, more elaborate theoretical models of neutrino masses have beenproposed, with the seesaw models being a particularly popular group of models inwhich new heavy particles generate neutrino masses. We study low-scale seesawmodels, in particular the resulting energy-scale dependence of the neutrino parameters,which incorporate new particles with masses within the reach of current andfuture experiments, such as the LHC. / Standardmodellen för partikelfysik beskriver den stora majoriteten data från partikelfysikexperimentutmärkt. Den kan emellertid inte i sin enklaste form beskrivadet faktum att neutriner är massiva partiklar och leptonsmakerna är blandande,vilket krävs enligt observationerna av neutrinooscillationer. Därför måste standardmodellenutökas för att ta hänsyn till detta, vilket öppnar upp möjligheten att utforska nya och intressanta fysikaliska fenomen. Det finns många föreslagna modeller för massiva neutriner. De enklaste av dessakan beskriva observationerna med endast ett fåtal effektiva parametrar. Dessutom är neutriner de enda kända befintliga partiklar som har potentialen att vara sinaegna antipartiklar, en möjlighet som aktivt undersöks genom experiment på neutrinolöst dubbelt betasönderfall. I denna avhandling analyserar vi dessa enkla modellermed Bayesisk inferens och begränsningar från neutrinorelaterade experiment och undersöker även potentialen för framtida experiment på neutrinolöst dubbelt betasönderfall att bergänsa andra typer av ny fysik. Även mer avancerade teoretiska modeller för neutrinomassor har föreslagits, med seesawmodeller som en särskilt populär grupp av modeller där nya tunga partiklargenererar neutrinomassor. Vi studerar seesawmodeller vid låga energier, i synnerhetneutrinoparametrarnas resulterande energiberoende, vilka inkluderar nya partiklarmed massor inom räckh°all för nuvarande och framtida experiment såsom LHC. / <p>QC 20130830</p>

Les crises économiques et financières et les facteurs favorisant leur occurrence / Empirical varieties and leading contexts of economic and financial crisesCabrol, Sébastien 31 May 2013 (has links)
Cette étude vise à mettre en lumière les différences et similarités existant entre les principales crises économiques et financières ayant frappé un échantillon de 21 pays avancés depuis 1981. Nous analyserons plus particulièrement la crise des subprimes que nous rapprocherons avec des épisodes antérieurs. Nous étudierons à la fois les années du déclenchement des turbulences (analyse typologique) ainsi que celles les précédant (prévision). Cette analyse sera fondée sur l’utilisation de la méthode CART (Classification And Regression Trees). Cette technique non linéaire et non paramétrique permet de prendre en compte les effets de seuil et les interactions entre variables explicatives de façon à révéler plusieurs contextes distincts explicatifs d’un même événement. Dans le cadre d‘un modèle de prévision, l’analyse des années précédant les crises nous indique que les variables à surveiller sont : la variation et la volatilité du cours de l’once d’or, le déficit du compte courant en pourcentage du PIB et la variation de l’openness ratio et enfin la variation et la volatilité du taux de change. Dans le cadre de l’analyse typologique, l’étude des différentes variétés de crise (année du déclenchement de la crise) nous permettra d’identifier deux principaux types de turbulence d’un point de vue empirique. En premier lieu, nous retiendrons les crises globales caractérisées par un fort ralentissement ou une baisse de l’activité aux Etats-Unis et une faible croissance du PIB dans les pays touchés. D’autre part, nous mettrons en évidence des crises idiosyncratiques propres à un pays donné et caractérisées par une inflation et une volatilité du taux de change élevées. / The aim of this thesis is to analyze, from an empirical point of view, both the different varieties of economic and financial crises (typological analysis) and the context’s characteristics, which could be associated with a likely occurrence of such events. Consequently, we analyze both: years seeing a crisis occurring and years preceding such events (leading contexts analysis, forecasting). This study contributes to the empirical literature by focusing exclusively on the crises in advanced economies over the last 30 years, by considering several theoretical types of crises and by taking into account a large number of both economic and financial explanatory variables. As part of this research, we also analyze stylized facts related to the 2007/2008 subprimes turmoil and our ability to foresee crises from an epistemological perspective. Our empirical results are based on the use of binary classification trees through CART (Classification And Regression Trees) methodology. This nonparametric and nonlinear statistical technique allows us to manage large data set and is suitable to identify threshold effects and complex interactions among variables. Furthermore, this methodology leads to characterize crises (or context preceding a crisis) by several distinct sets of independent variables. Thus, we identify as leading indicators of economic and financial crises: variation and volatility of both gold prices and nominal exchange rates, as well as current account balance (as % of GDP) and change in openness ratio. Regarding the typological analysis, we figure out two main different empirical varieties of crises. First, we highlight « global type » crises characterized by a slowdown in US economic activity (stressing the role and influence of the USA in global economic conditions) and low GDP growth in the countries affected by the turmoil. Second, we find that country-specific high level of both inflation and exchange rates volatility could be considered as evidence of « idiosyncratic type » crises.
