How Effective are Macroprudential Policies? An Empirical Investigation
In recent years, policymakers have generally relied on macroprudential policies to address financial stability concerns. However, our understanding of these policies and their efficacy is limited.

The effectiveness of these policies in curbing bank credit growth and house price inflation is then assessed using a dynamic panel data model. The main findings of the paper are: (1) ...

Over the same period, inventor employment has become increasingly concentrated in large firms, rising six times more than overall employment concentration. To explain these trends, we develop a new model of endogenous team formation within firms and embed it in a general equilibrium model of the inventor labor market. Teams increase firms’ returns to scale by increasing the likelihood of productive matches between inventors. The value of these matches rises over time, possibly driven by ...
