January 2015The Effect of Regulatory Harmonization on Cross-border Labor Migration: Evidence from the Accounting Profession
with Matthew J. Bloomfield, Ulf Br├╝ggemann, 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.

Our research design compares the cross-border migration of accounting professionals relative to tightly-matched other professionals before and after regulatory harmonization.

We provide evidence that this effect is due to harmonization, rather than increases in the demand for accounting services d...
January 2011Capital-Market Effects of Securities Regulation: Prior Conditions, Implementation, and Enforcement
with Luzi Hail, Christian Leuz: w16737
We examine the capital-market effects of changes in securities regulation in the European Union (EU) aimed at reducing market abuse and increasing transparency. To estimate causal effects for the population of EU firms, we exploit that for plausibly exogenous reasons, like national legislative procedures, EU countries adopted these directives at different times. We find significant increases in market liquidity, but the effects are stronger in countries with stricter implementation and traditionally more stringent securities regulation. The findings suggest that countries with initially weaker regulation do not catch up with stronger countries, and that countries diverge more upon harmonizing regulation.
