[en] ADVERSE SELECTION AND COMPETITION IN THE MARKET FOR HOUSEHOLD CREDIT IN BRAZIL / [pt] SELEÇÃO ADVERSA E CONCORRÊNCIA NO MERCADO DE CRÉDITO PARA PESSOA FÍSICA NO BRASIL

PEDRO HENRIQUE ROSADO DE CASTRO 24 September 2008 (has links)
[pt] Este trabalho testa e encontra evidência de que as taxas de juros de empréstimos bancários respondem mais a aumentos do que a quedas na taxa básica de juros (Selic). A assimetria sobrevive a uma análise de evento, na qual a disponibilidade de uma base com dados diários é explorada com o objetivo de isolar o choque de política monetária sobre os juros. Dentre as potencias teorias que racionalizam essa assimetria, duas são consideradas. A primeira refere-se à existência de poder de mercado, o que permite aos bancos coordenarem um menor repasse como forma de aumentar os lucros de curto prazo. A segunda argumenta que a presença de forte seleção adversa no mercado de crédito diminui o incentivo à concorrência na dimensão preço, reduzindo o repasse de quedas no custo de captação. Como as duas hipóteses produzem implicações empíricas similares em forma reduzida, o artigo propõe e estima um modelo estrutural a fim de testar qual dos dois modelos melhor se ajusta aos preços e quantidades observados no mercado de crédito para pessoa física. / [en] This paper tests and find evidence that support the view that credit interest rates respond more to increases than to decreases in the Central Bank basic interest rate (Selic). This asymmetry is robust to an event analysis, in which the availability of a dataset containing daily information is explored in order to isolate monetary policy shocks on interest rates. Among the possible explanations for this asymmetry, two are considered in the article. The first one refers to the existence of market power, which allows banks to coordinate on a smaller pass-through in order to increase profits in the short run. The second refers to the potential existence of severe adverse selection issues in the credit market, which diminishes the incentives to compete on the interest rate dimension and consequently the pass-through from decreases in the cost of funds. Since the two theories present similar empirical implications in reduced forma analysis, the article proposes and estimates a structural model in order to test which of the competing theories better fits the observed data on prices and quantities for household credit in Brazil.
