He has played a major role in developing and studying U.S. longitudinal firm-level data. Using these data, he has developed new statistical measures and analyzed the determinants of firm-level job creation, job destruction and economic performance. He has explored the implications of these firm dynamics for aggregate U.S. productivity growth and for the U.S. labor market. The statistical and measurement methods he has helped develop to measure and study firm dynamics have been increasingly used by many statistical agencies around the world. His own research increasingly uses the data and measures on firm dynamics from a substantial number of advanced, emerging and transition economies.
