The spenders-hoarders theory of capital accumulations, wealth distribution and fiscal policy

This paper proposes a simple OLG model which is consistent with the essential facts about consumer behavior, capital accumulation and wealth distribution, and yields some new and surprising conclusions about fiscal policy. By considering a society in which individuais are distinguished according to two characteristics, altruism and wealth preference, we show that those who in the long run hold the bulk of private capital are not so rnuch motivated by dynastic altruism as by preference for wealth. Two types of social segmentation can result with different wcalth distribution. To a large extcnt our results seem to fit reality better than those obtained with standard optimal growth models in which dynastic altruism ( or r ate o f impatience) is the only source of heterogeneity: overaccumulation can appear, public debt and unfunded pensions are not neutra!, estate taxation can improve the welfare of the top wealthy.

Life Cycle Models, Heterogeneity of Initial Assets,and Wealth Inequality

Life cycle general equilibrium models with heterogeneous agents have a very hard time reproducing the American wealth distribution. A common assumption made in this literature is that all young adults enter the economy with no initial assets. In this article, we relax this assumption – not supported by the data - and evaluate the ability of an otherwise standard life cycle model to account for the U.S. wealth inequality. The new feature of the model is that agents enter the economy with assets drawn from an initial distribution of assets, which is estimated using a non-parametric method applied to data from the Survey of Consumer Finances. We found that heterogeneity with respect to initial wealth is key for this class of models to replicate the data. According to our results, American inequality can be explained almost entirely by the fact that some individuals are lucky enough to be born into wealth, while others are born with few or no assets.

Essays on health care reform, wealth inequality, and demography

This thesis contains three chapters. The first chapter uses a general equilibrium framework to simulate and compare the long run effects of the Patient Protection and Affordable Care Act (PPACA) and of health care costs reduction policies on macroeconomic variables, government budget, and welfare of individuals. We found that all policies were able to reduce uninsured population, with the PPACA being more effective than cost reductions. The PPACA increased public deficit mainly due to the Medicaid expansion, forcing tax hikes. On the other hand, cost reductions alleviated the fiscal burden of public insurance, reducing public deficit and taxes. Regarding welfare effects, the PPACA as a whole and cost reductions are welfare improving. High welfare gains would be achieved if the U.S. medical costs followed the same trend of OECD countries. Besides, feasible cost reductions are more welfare improving than most of the PPACA components, proving to be a good alternative. The second chapter documents that life cycle general equilibrium models with heterogeneous agents have a very hard time reproducing the American wealth distribution. A common assumption made in this literature is that all young adults enter the economy with no initial assets. In this chapter, we relax this assumption – not supported by the data – and evaluate the ability of an otherwise standard life cycle model to account for the U.S. wealth inequality. The new feature of the model is that agents enter the economy with assets drawn from an initial distribution of assets. We found that heterogeneity with respect to initial wealth is key for this class of models to replicate the data. According to our results, American inequality can be explained almost entirely by the fact that some individuals are lucky enough to be born into wealth, while others are born with few or no assets. The third chapter documents that a common assumption adopted in life cycle general equilibrium models is that the population is stable at steady state, that is, its relative age distribution becomes constant over time. An open question is whether the demographic assumptions commonly adopted in these models in fact imply that the population becomes stable. In this chapter we prove the existence of a stable population in a demographic environment where both the age-specific mortality rates and the population growth rate are constant over time, the setup commonly adopted in life cycle general equilibrium models. Hence, the stability of the population do not need to be taken as assumption in these models.

Gestão e sucessão de empresas familiares: uma revisão de literatura.

O presente estudo contempla propostas para algumas lacunas encontradas nos trabalhos sobre empresas familiares, por meio de uma análise da produção científica, com enfoque conceitual e no relacionamento intergeracional, de todos os artigos publicados nos eventos da Associação Nacional de Pós-Graduação e Pesquisa em Administração (EnANPAD, Eneo, 3ES e EnGPR), e nos periódicos RAC, RAE, RAUSP e O&S, no período de 1961 a 2008, de acordo com a disponibilidade em seus sitios, realizada em outubro de 2008, além de consultas nas bibliotecas da Fundação Getúlio Vargas, no Rio de Janeiro (em dezembro de 2008) e em São Paulo (em dezembro de 2008 e em maio de 2009). Nove critérios de análise foram utilizados: pesquisas em empresas familiares, frequência das publicações, citações e referências, autores mais prolíficos, instituições que mais publicam, média de artigos publicados, fundamentação teórica das investigações, aspectos conceituais e pai e filho. Dos 154 artigos encontrados que, a priori, estavam direcionados para esta temática, somente 89 foram incluídos por apresentarem adequação aos objetivos da pesquisa. Os resultados alcançados revelam diversas contradições entre as pesquisas, tanto sob o ponto de vista conceitual quanto metodológico. Não é possível, ainda, encontrar um conceito de empresa familiar. Diversos fatores influenciam na imagem negativa associada a essas organizações, mas que não vão ser capazes de ofuscar o brilhantismo daquelas que são as principais responsáveis pela distribuição de riqueza, geração de emprego e crescimento econômico, no Brasil e no mundo. E quando aproveitam as vantagens competitivas que possuem, são capazes de se sobressair perante a concorrência e reverter qualquer situação que vá de contra aos seus interesses.
