THE CYCLICALITY OF PRICE‐COST MARGINS IN BANKING: AN EMPIRICAL ANALYSIS OF ITS DETERMINANTS

We study the determinants of the cyclical behavior of banks' price‐cost margins in the United States banking sector, using time series quarterly data for the period 1979–2005. We contribute to the literature by building an empirical model of the countercyclical behavior of these margins first documented by Aliaga‐Díaz and Olivero (2010a) . Doing so we are able to explore potential explanations for this behavior, and to show that margins are consistently countercyclical, even after controlling for the effects of credit risk and monetary policy. As a mechanism for the propagation of aggregate shocks, the countercyclical nature of margins in banking can provide additional support to stabilization policy. (JEL E32, E44, G21)
