RESUMO
This PhD thesis is divided in three essays on empirical microeconomics of banking. The first essay evaluates the competitive impact of public banks vis-à-vis private ones. A methodology based on Bresnahan and Reiss (1991) is used to access competition in local concentrated markets. We find robust evidence that, relative to private banks, state- owned banks are anti-competitive. In the second essay the introduction of a new type of credit, the payroll loans, is analyzed. In this type of credit there is a complete collateralization of the debt through the direct withdrawal of the loan payment from the debtor`s salary. In order to properly measure this effect we used another type of credit, automobile loans, as control group. Results show a statistical and economic significant reduction of interest rate and increase of credit volume, which show that the creation of payroll loans had strong effect on the Brazilian credit market. In the third chapter I study the relation between monetary policy and banking credit market. The international literature, both theoretical and empirical, suggests that credit markets could have important role in the amplification of monetary policy shocks. In this essay I focus on the banking credit market and what literature calls banking lending channel. Using a new identification strategy, based on an event study around monetary policy committee reunion setting the basic interest rate target, I find no evidence of banking lending channel in Brazil. Despite the significant direct effect of basic interest rate on credit interest rate and volume, there is no link between this effect and the banking lending channel, since smaller and/or less liquid banks do not react more to the monetary policy shocks than bigger and/or more liquid banks.
