January 2015The Effect of Regulatory Harmonization on Cross-border Labor Migration: Evidence from the Accounting Profession
with Matthew J. Bloomfield, Hans B. Christensen, Christian Leuz: w20888
The paper examines whether international regulatory harmonization increases cross-border labor migration. To study this question, we analyze European Union (EU) initiatives that harmonized accounting and auditing standards.

We also exploit the institutional richness of the OTC market and analyze two key dimensions of market quality, liquidity and crash risk, across firms and regulatory regimes. We find that OTC firms that are subject to stricter regulatory regimes and disclosure requirements have higher market quality (higher liquidity and lower crash risk). Our analysis points to an important trade-off in regulating the OTC market and protecting investors: Lowering regulatory requirement...
