This paper presents a tractable framework with endogenous default and evaluates the welfare implication of bank capital requirements. We analyze the response of social welfare to a negative technology shock under different capital requirement regimes with and without default. We show that including default as an additional indicator of capital requirements is welfare improving. When implementing capital requirements, a more aggressive reaction to the default rate is more effective for weakening the negative effect of the shock on welfare. Compared with output gap, the credit-to-output gap is a better indicator for implementing the countercyclical capital buffer.JEL Classification: E44, E47, E58, G28

This study documents the adjustment in the business cycles of Mexico’s states that resulted from trade liberalization. It also analyzes the relevance of the various elements that previous studies have proposed as the determining factors of the synchronization of these cycles. Our results reveal that these determinants are relevant throughout the sample period (1980-2019), but their relative importance changes over time as does their synchronization. This may be explained as follows: trade liberalization caused a regional and sectoral reallocation of resources, which in turn led to some states becoming increasingly interlinked based on their economic structures, whereas the remaining states became less synchronized with the former states. This case should be of interest to other developing countries that are dependent on the world’s capital and trade flows and whose regions may respond heterogeneously if they have diverse economic structures as those of Mexico.
