Development in European Union is showing that even despite high amount of effort in economic integration, differences in cross-country development are still at play. Indications about Lucas Paradox can be observed, due to inefficient flow of capital. Aim of this study is to quantify, whether this Lucas paradox is present in EU and how it contributes to convergence or divergence between countries. Comparison of panel VAR impulse-response functions is used for evaluation. Results suggests, that Lucas paradox can be identified between Euro area vs non-Euro area countries and Euro area core vs periphery. Furthermore, capital misallocation regarding these four groups prevents possible short-term economic convergence.

This thesis focuses on the analysis and description of the causes of trends in the accumulation of foreign exchange reserves in three selected Asian economies, China, Singapore and Hong Kong. In the analysis are examined selected factors whose relationship with the foreign reserves, based on their merits and in the work of this association subsequently investigated on empirical data, mainly from the balance of payments and the statement of net investment position to identify and specify the main causes of accumulation of foreign exchange reserves in individual economies. The general framework of work consists of the theories of international movement of capital, specifically called Lucas's paradox, whose presence adds insight about other possible causes of some capital flows.

[pt] Primeiramente, o trabalho examina em que medida os países pobres possuem retornos de capital mais elevados que os países ricos. Em segundo lugar, investiga se as diferenças nos retornos de capital entre países estão correlacionadas com fatores institucionais, variância e/ou assimetria nos retornos. Os resultados indicam uma relação negativa entre os retornos e o PIB per capita mas com pouca significância econômica. Ademais, os resultados indicam correlações significantes entre retornos de capital e alguns fatores institucionais, embora esses também não sejam economicamente significativos. O desvio padrão ou a assimetria nos retornos não parecem estar correlacionados com os retornos. Em suma, os achados indicam que uma pior qualidade institucional é, até certo ponto, uma explicação plausível para altos retornos de capital nos países pobres. Ainda assim, a falta de significância econômica encontrada destaca a natureza idiossincrática dos retornos nesta indústria devido a independência entre retornos e fatores específicos ao país. Os resultados indicam a necessidade de adaptar a teoria economia à differenças setoriais e também é importante na prática para empresas privadas no setor de petróleo e gás, pois os resultados indicam que estas não devem se preocupar particularmente com o PIB per capita ou as instituições dos países em que considera investir. Ao invés disso, os resultados indicam que as empresas devem olhar principalmente para características dos poços mesmo. Diversas explicações plausíveis para os resultados são delineadas. / [en] This thesis makes use of a unique and vast dataset of investment and production in the oil and gas industry from 1950 to 2016, to explore the Lucas Paradox and the drivers of returns to capital in the industry. Firstly, the thesis examines to what extent poor countries possess higher average returns to capital than rich countries. Secondly, it investigates whether the differences in returns between countries are correlated with institutional factors, variance and/or asymmetry in the returns. The results demonstrate that poorer countries have enjoyed significantly higher returns to capital than richer countries. Moreover, the findings show that institutional factors such as property rights protection, level of corruption and level of schooling possess a positive and statistically significant correlation with returns to capital. However, both these findings are not particularly economically significant. Variance and asymmetry of the returns appear to be an irrelevant explanation for the Lucas Paradox. On the other hand, asset-specific factors, that were, ex-ante, expected to be merely insignificant control variables, such as the size of the reservoir, or whether the asset is located onshore or offshore, have large R-squared impact on returns to capital. The findings in this thesis are important because the largely insignificant magnitude of country-specific variables highlight the importance of adapting economic development theory to account for sector-specific differences, as emphasized by Feyrer and Caselli (2008). Moreover, the results indicate that profit maximizing oil and gas companies considering new investments in a country should not be overly concerned with the GDP per capita nor the institutional quality of the country in question. Several potential explanations and paths for future studies are delineated.

This thesis presents three essays on the main determinants and regulations of international capital flows. The essays contribute to an ongoing significant debate among scholars and practitioners on what determines international capital flows by examining the following issues: Global liquidity, market sentiment and financial stability indices; Global liquidity and capital flow regulations; and Global governance and gross capital flows dynamics. In the first essay, we explore the main determinants of global liquidity, measured using cross-border claims of banks, and establish the link between a variety of financial stability indices and global liquidity. For a sample of 149 countries between 2000 and 2016, we find that Bloomberg Financial Stability Indices are more powerful in explaining global liquidity than FRED Financial Stress Indices and the Euro Area Systemic Stress Composite Indicator (CISS). Moreover, both market sentiment indices, namely the US Conference Board Leading Economic Index (LEI) and the US IBD/TIPP Economic Optimism Index are economically and statistically significant on cross-border bank flows. The research provides useful insights on what market sentiment and financial stability indices are better to employ for financial markets surveillance and as such practice of investment management. We argue that anyone interested in using financial stability indices as indicators of financial conditions and the level of financial stress would benefit from tracking several indices and not just one. The second essay examines the effectiveness of capital controls and macroprudential policies as ways to manage the volume of international capital flows, controlling for other determinants. The findings show that capital controls imposed on inflows generally prevail over controls imposed on outflows in reducing the magnitude of capital flows. The results are consistent with the pecking order theory on capital flows and are connected with the riskiness of different asset classes. For a sample of 112 countries over 2000 and 2016, we find that FX and/or countercyclical reserve (RR_REV) and general countercyclical capital buffer requirements (CTC), reserve requirement ratios (RR) and concentration limits (CONC) are the most effective macroprudential policies for managing countries' exposures to global liquidity fluctuations. Moreover, progress is being made to reduce the systemic risks created by systemically important financial institutions (SIFIs) using macroprudential policies. The results reflect recent developments in Basel III regulations and shed light on the effective calibration of capital flow regulations to country-specific circumstances. The final essay examines the link between global governance indicators and patterns of gross capital flows, controlling for other determinants. For a sample of 67 countries between 2000 and 2016, we contribute to explain the existence of the Lucas paradox (1990) on "why doesn't capital flow from rich to poor countries" and the Feldstein-Horioka puzzle (1980). The findings show that institutional quality rather than the effect of diminishing returns of capital is a key explanation for the Lucas paradox. Finally, we provide new evidence on the relationship between the multidimensional nature of financial development and gross capital flows. The findings show the importance and predominance of financial institutions versus financial markets in the dissemination of international capital flows across counties.

La mondialisation financière des dernières décennies témoigne du phénomène du déséquilibre mondial dans lequel les comptes déficitaires actuels de certaines grandes économies avancées sont continuellement financés par certains pays en développement avec des taux de croissance élevés et des stocks de capitaux rares. Sur le plan théorique, le modèle de croissance néoclassique implique qu’une économie avec une pénurie de capitaux aurait un produit marginal élevé de capital et un taux d’intérêt élevé d’autarcie. Par conséquent, lors de l’intégration avec la capitale mobile gratuite, ce pays éprouverait les entrées nettes de capitaux nets afin que le taux d’intérêt domestique soit égal au reste du taux mondial (Lucas 1990). De plus, une économie qui se développe plus rapidement que le reste du monde aurait également une demande d’investissement plus élevée et devrait connaître les entrées de capitaux totaux nets (Gourinchas and Jeanne 2013). Les déséquilibres mondiaux sont le résultat de l’hétérogénéité des tendances de l’épargne et des investissements dans tous les pays. En effet, un pays connaît un apport de capitaux si son économie est inférieure à son investissement : ce pays emprunte au reste du monde si sa sauvegarde est supérieure à son investissement. La thèse emploierait la croissance de la productivité pour afficher les sources de lumière sur cette hétérogénéité entre les pays. [...] / The financial globalization for the past decades witnesses the global imbalance phenomenon on which the deficit current accounts by some large advanced economics are continuously financed by some developing economies with the high output growth rates and the scarce capital stocks. On the theoretical ground, the Neo-Classical growth model implies that one economy with scarcity of capital would have a high marginal product of capital and a high autarky interest rate therefore, at the integration with the free mobile capital, that country would experience the net total capital inflows so that the domestic interest rate equals that to the rest of world’s rate (Lucas 1990). Furthermore, one economy growing faster than the rest of the world would also have a higher investment demand and should experience the inflows of net total capitals (Gourinchas and Jeanne 2015). The global imbalances are the result of the heterogeneity in the patterns of savings and investments across countries. Indeed, one country experiences an inflow of capital if its saving is less that its investment: that country borrows from the rest of the world to finance the excess investment demand. Similarly, one country would lend to the rest of the world if its saving is higher than its investment. The thesis would employ the productivity growth to shed the refresh lights on this heterogeneity across countries. [...]
