In recent years, the increased concentration of activity in the banking system has received much attention. This paper studies the implications of concentration in the banking sector for economic activity. Changes in the competitive structure affect investment, risk-sharing, and social welfare. A key aspect of our analysis is that banks in more concentrated systems allocate a lot of resources t...

We analyze an economy populated by a sequence of generations who decide over their consumption levels and the levels of investment in human capital of their immediate descendants. The objective of the paper is to identify the impact of strategic interactions between consecutive generations on the time path of human capital accumulation. To this end, we characterize the Markov perfect equilibriu...

Investment in human capital accumulation, government consumption and total government expenditures present a striking negative correlation with capital shares. This correlation is robust to alternative speci...cations, lists of controls, and exclusion of outliers. Causality tests strongly support the hypothesis that the direction of causation runs from capital shares to the government spending ...

This paper develops a uni...ed theory for the dynamic implications of income inequality on the process of development. The proposed theory argues that the replacement of physical capital accumulation by human capital accumulation as a prime engine of economic growth has changed the qualitative impact of inequality on the process of development. In early stages of industrialization as physical c...

Central banks’ foreign exchange holdings have increased significantly in the recent past. This article explains this development as a result of the liberalisation of international capital markets. First, central banks accumulate reserves in order to protect the economy from detrimental effects of sudden stops in capital flows and flow reversals. Second, central banks use the accumulation of res...

This paper investigates the relationship between per capita human capital investment and the fertility rate. In the first part of the article we analyze a theoretical model with endogenous birth rate in which we do not make any assumption on how fertility directly affects per capita human capital accumulation. The results obtained in this model are then compared with those of a more traditional...

The paper analyzes the joint evolution of accumulation and distribution of human capital in an OLG framework. Dynamics arises as a result of a continuous interplay between features of the human capital distribution and individual variables inherited human capital and inborn ability. Such interaction drives individual investment in human capital and accumulation in the economy. According to the ...
