The aim of this diploma thesis was to analyze an influence of most important humanitarian actors and evaluate their cooperation and efficiency. The task of this thesis was too to show that humanitarian and development aid doesn't have to bring expectable results every time. Low effectiveness of humanitarian activities isn't only the consequence of an insufficient coordination of humanitarian organizations, but it particularly caused by features of a given country, its institutions, its rules and non-existing democracy. On the basis of this knowledge, the analysis of humanitarian aid in Haiti was conducted in this work, which became known to the public all over the world due to a devastating earthquake in January 2010, in spite of the fact that its economic situation has been for very poor for a long time before. The thesis also points on some mistakes of humanitarian organizations in the most important sectors and suggests its solution. I see the solution in a shift from a short-term and passive aid to the long-term and actively-received aid.

Thesis (doctoral)--Universität, Linz, 2004. / Includes bibliographical references (p. 244-256).

Cette thèse s’intéresse à la relation de long-terme entre la longévité et le développement économique. Dans le premier chapitre, j’analyse l’impact des dépenses de santé sur la croissance et le bien-être. Pour cela, j’étudie l’influence du taux d’imposition dans une économie avec temps de vie endogène (Chakraborty (2004)). Je détermine le taux d’imposition qui maximise le taux de croissance. Puis je m’intéresse aux variations du niveau de production dans l’état stationnaire par rapport au taux d’imposition. Enfin, j’étudie le taux d’imposition qui maximise le bien-être dans l’état stationnaire. Dans le second chapitre, j'analyse l’impact sur la croissance de dépenses de santé choisies par les agents. En effet, je développe un modèle de croissance endogène dans lequel les individus peuvent dépenser des ressources pour vivre plus longtemps dans leur période de retraite. Je donne une caractérisation complète de l’équilibre général dynamique puis je détermine l’impact sur la croissance des dépenses de santé. Enfin, le troisième chapitre étudie l’impact théorique du vieillissement sur l’allocation sectorielle des travailleurs. Je développe un modèle multi-sectoriel dans lequel j’examine les conséquences sur le revenu par travailleur et l’allocation sectorielle des travailleurs d’un choc de longévité et de fertilité. Je montre que contrairement aux modèles uni-sectoriels, le revenu n’est pas forcément monotone par rapport aux variables démographiques. Des chocs démographiques réalistes produisent des mouvements non-négligeables de travailleurs. / This dissertation is interested in the long-run relationship between longevity and economic development. In the first chapter, I analyse the impact of health expenditures on economic growth and welfare. For this, I study the influence of the tax rate in an economy à la Chakraborty (2004). I first determine the growth-maximizing tax rate, which is shown to be 0 in low-income countries. Second, I show that the steady-state income level is an inverted U-shaped function or a decreasing function of the tax rate. Third, I study the tax rate that maximizes the steady-state welfare level. In the second chapter, I propose a theoretical model to study the growth impacts of health expenditures chosen by the agents. Indeed, I develop a Diamond model with endogenous growth in which young individuals can spend resources to increase their longevity in retirement period. I give a full characterization of the dynamic general equilibrium and determine the growth impacts of health expenditures. They can speed up or slow down economic growth. They can be a barrier or a necessity for growth to take place. A calibration to OECD countries suggests that the latter case is the most likely one. Finally, the third chapter studies the theoretical impact of the aging process on the sectorial labor allocation. To this aim, I develop a multi-sector two-period overlapping generations model in which I examine the consequences of both a longevity shift and a fertility shift on the labor allocation of the economy and on the income per worker level. I show that contrary to one-sector models, the income per worker level is not necessarily monotonic with respect to demographic variables. Realistic demographic shocks are also shown to create significant labor reallocation across sectors.

As a result, the private health care market has grown in recent years, which has changed the role of the state from executive to regulator of that sector. Regulation includes tackling the economic and financial issue. Our study aimed to identify the behavior of financing strategies adopted by medical cooperatives and group medicines to meet the regulatory benchmarks of the supplementary health care sector in Brazil. The survey results show that the mandatory Guaranteeing Assets (Ativos Garantidores, AG), 1st regulatory moment, resulted in a significant increase of both the overall and the long term indebtedness indexes, which reveals the use of Third-party capital instead of Equity capital. Only the Medical Cooperatives featured increased Overall Indebtedness, which means that the Medical Cooperatives, unlike Group Medicines, are capitalized by third party funds rather than by Equity Capital. Both modalities adopted the strategy of increasing their long-term debt and reducing their short term debt (debt composition). With the introduction of the Health Guarantor Fund (Fundo Garantidor da Sa??de, FGS), 2nd regulatory moment, the Overall and Current Liquidity indexes decreased, showing that the goal of the FGS program to reduce financial guarantees and to improve working capital wasn't met. Medical Cooperatives managed to reduce their overall debt, whereas the overall debt of Group Medicines increased. We conclude that there was a balance between the Indebtedness indexes and Liquidity over the period and that operators who wish to remain in the market must comply with the rules, adapting and improving the quality of their management / A rede p??blica de sa??de no Brasil ?? prec??ria e n??o atende de forma plena ??s necessidades da popula????o. Consequentemente, o mercado privado de assist??ncia ?? sa??de tem crescido nos ??ltimos anos e com isso a fun????o do Estado vem se alterando, passando de executor para regulador deste setor de atividade. Um alvo da regula????o ?? a quest??o econ??mico-financeira. Nesse sentido, este trabalho tem como objetivo identificar o comportamento das estrat??gias de financiamento adotadas pelas cooperativas m??dicas e medicinas de grupo frente aos marcos regulat??rios do setor de sa??de suplementar no Brasil. Os resultados da pesquisa indicam que com a obrigatoriedade dos Ativos Garantidores - AG, 1?? momento regulat??rio, os ??ndices de Endividamento, tanto geral quanto de longo prazo tiveram um aumento significativo, o que indica a utiliza????o de Capital de Terceiros ao inv??s do Capital Pr??prio. Observou-se que apenas as Cooperativas M??dicas apresentaram um aumento no Endividamento Geral. Isso indicou que as Cooperativas M??dicas, diferentemente, das Medicinas de Grupo, se capitalizaram com recursos de terceiros ao inv??s do Capital Pr??prio. Notou-se que ambas as modalidades adotaram a estrat??gia de aumentar a d??vida de longo prazo e reduzir as de curto prazo (composi????o do endividamento). Com a institui????o do Fundo Garantidor da Sa??de - FGS, 2?? momento regulat??rio, os ??ndices de Liquidez Geral e Corrente diminu??ram, indicando que a proposta do programa FGS, de reduzir as garantias financeiras e melhorar o capital de giro, n??o ocorreu. Observou-se que para as Cooperativas M??dicas o endividamento geral diminuiu e em contrapartida para as Medicinas de Grupo aumentou. Contudo, conclui-se que houve um equil??brio entre os ??ndices de Endividamento e Liquidez ao longo do per??odo e que para as operadoras se manterem no mercado ter??o que atender as regras, adaptando-se e melhorando a qualidade da sua gest??o

Pendant des décennies, les économistes se sont intéressés à étudier pourquoi et comment les agents s'entraident, en accordant une place particulière à l'analyse des transferts de revenus privés. Les applications récentes comprennent des sujets très divers tels que: l'analyse de l'accumulation du capital, la cohésion sociale etla solidarité, le marché de l'assurance et des taux d'intérêt, les stratégies de gestion des risques face aux chocs négatifset les politiques gouvernementales.La présente thèse analyse de quelles manières les décisions de transfert entre ménages, les envois de fonds internationauxet les transferts intra-ménages ont un impact sur cinq aspects fondamentaux du développement:(i) les interactions sociales, (ii) le travail de marché et domestique, (iii) les dépenses, (iv) la nutrition et (v) la santé.Trois questions de recherche sont traitées en utilisant des données provenant de la Colombie, de l'Équateur et du Pérou, ainsi que de multiples techniques économétriques. Premièrement, y a-t-il une relation entre les transferts entre ménages et la distance entre les donateurs et les récepteurs? Deuxièmement, faire des envois de fonds internationaux modifie-t-il de manière asymétrique l'offre de travail, en fonction des caractéristiques individuelles? Troisièmement, avoir recours des transferts intra-ménages influence-t-il les habitudes de dépenses, la nutrition et la santé au sein des ménages?Les résultats suggèrent que les transferts de revenus privés jouent un rôle clé de redistribution, en modifiant leniveau de vie et en améliorant le bien-être des individus. Dans des contextes de pauvreté, où les mécanismes d'apparentant à une sécurité sociale sont rares, où l'informalité est courante, où les institutions sont fragmentées et où le secteur public est faible, les transferts d'argent et en nature entre ménages constituent des stratégies essentielles de subsistance. Ainsi, améliorer notre compréhension de cette dimension des comportements sociaux est fondamental. / For decades, economists have been interested in studying why and how agents support eachothers, giving a special place to the analysis of private income transfers. Recent applicationsinclude very diverse topics such as: the analysis of capital accumulation, social cohesion andsolidarity, market insurance and interest rates, risk-coping strategies against negative shocksand government policies.The present dissertation analyzes how inter-household transfer decisions, international remittancesand intra-household transfers contribute to shape five fundamental aspects of development:(i) social interactions, (ii) market and household work, (iii) spending patterns, (iv)nutrition and (v) health.Three research questions are addressed using applied data from Colombia, Ecuador and Peru,and multiple econometric techniques. First, is there a relationship between inter-householdtransfer dynamics and distance between donors and receivers? Second, do remittances asymmetricallyshape labor supply responses depending on people’s characteristics? Third, dointra-household transfers influence spending patterns, nutrition and health outcomes?Results suggest that private income transfers play a key re-distributive role, shaping agents’living standards and improving individual and social well-being. In contexts of economic deprivation,where social safety nets are scarce, informality is at stake, institutions are highlyfragmented and the public sector is weak, money and in-kind help from other households orindividuals constitute crucial livelihood strategies to get through the economic world. Thus,enhancing our understanding of this dimension of social behaviors is a must.
