Cross-border bank positions in Asia and the Pacific remain highly concentrated to few counterparties, exposing the region to financial risks and policy spillovers. Consequently, assessing the determinants and impacts of the region's cross-border banking concentration is relevant to the design of...

This article analyzes the effect of valuations-based capital requirements and concentration risk provisions on the risk-shifting response of the banking sector to monetary easing. It provides a closed economy DSGE model for the Euro zone with costly bank capital and two heterogeneous borrowers....

How does bank capital affect the relationship between bank concentration and risk taking? I develop a tractable dynamic model with heterogeneous financially constrained entrepreneurs and an imperfectly competitive banking sector. Based on the model, when the bank capital ratio exceeds the...

This paper analyzes the implications of the gradual rise in bank concentration since the 1990s for the transmission of monetary policy. I use branch-level data on deposit and loan rates to evaluate the monetary policy pass-through conditional on the level of local bank concentration and bank...

This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

During the last thirty years, U.S. bank concentration has been growing over time, as has bank capital ratio, which has been rising and already well above the minimum capital requirement. To explain these findings, I develop a tractable dynamic model with two key elements: financial constrained...

Larger firms (by sales or employment) have higher leverage. This pattern is explained using a model in which firms produce multiple varieties, acquire new varieties from their inventors, and borrow against the future cash flow of the firm with the option to default. A variety can die with a...

This paper analyzes the implications of the recent rise in bank concentration for the transmission of monetary policy. First, I use branch-level data on deposit and loan rates to evaluate the monetary policy pass-through conditional on the level of local bank concentration and bank...
