We develop a dynamic general equilibrium model of capital accumulation where credit is intermediated by banks operating in a Cournot oligopoly. The number of banks affects capital accumulation through two channels. First, it affects the quantity of credit available to entrepreneurs. Second, it...

This paper shows that bank competition has an intrinsically ambiguous effect on capital accumulation and economic growth. We further demonstrate that banking market structure can be responsible for the emergence of development traps in economies that would otherwise be characterized by unique...

In this paper we show that bank competition has an intrinsically ambiguous impact on capital accumulation. We further show that it is also responsible for the emergence of development traps in economies that otherwise would be characterized by unique equilibria. These results explain the...

It is becoming increasingly clear that the evaluation of policy measures that affect the growth performance of the economy requires adequate treatment of their effects on technological change. Environmental policy and regulations fit in this category. In this paper, I study the effects of taxes...

In industrial economies, firms build their market position by consistently investing in R&D over time and accumulating knowledge protected by secrecy, patents and other appropriability devices. To explore the macroeconomic implications of this fact, I construct an economy where oligopolistic...

To account for the qualitative differences between developed and developing countries, this paper argues that the expensive in-house R&D that manufacturing firms undertake in advanced industrial economies cannot be supported in countries that are in the early stage of industrialization and do...

We study the impact of corporate governance frictions in an economy where growth is driven both by the foundation of new …rms and by the in-house investment of incumbent …rms. Firms managers engage in tunneling and empire building activities. Active shareholders monitor man- agers, but can...
