Financial intermediation and occupational choice in development

This paper presents evidence that the spread between the marginal product of capital and the return on financial assets is mich higher in poor than in rich countries. A model with costly intermediation is developed. In this economy, individuals choose at each instant whether to work or to operate a technology. Entrepreneurs finance their business with their own savings and, if necessary, by borrowing from banks. I find that in this framework intermediation costs are not equivalent to a tax on the return of capital. The equivalence fails because costly intermediation not only affects the capital accumulation decision but also the occupational choice decision. I show that intermediation costs have important effects on per capita output and average business size in the economy. I conclude that taxing financial intermediaries can be a very bad policy for development.
