Asset Manager Commonality and Portfolio Similarity
Asset managers are increasingly influential in financial markets.

Nevertheless, the effect is primarily driven by purchases rather than sales and the resulting ...

The Impact of Regulatory Stress Tests on Bank Lending and Its Macroeconomic Consequences
We use an expansive regulatory loan-level data set to analyze how the portfolios of the largest US banks have changed in response to the Dodd-Frank Act Stress Test (DFAST) requirements. We find that the portfolios of the largest banks, which are subject to stress-testing, have become more similar to each other since DFAST was implemented in 2011. We also find that banks with poor stress-test results tend to adjust their portfolios in a way that makes them more similar to the portfolios of banks that performed well in the stress-testing. In general, stress-testing has resulted in more ...

Stress testing effects on portfolio similarities among large US Banks
We use an expansive regulatory loan-level dataset to analyze how the portfolios of the largest US banks have evolved since 2011. In particular, we analyze how the commercial and industrial and commercial real estate loan portfolios have changed in response to stress-testing requirements stipulated in the 2010 Dodd-Frank Act. We find that the largest US banks, which are subject to stress testing, have become more similar since the current form of the stress testing was implemented in 2011. We also find that banks with poor stress test results tend to adjust their portfolios in a way that makes ...
