The paper offers some reflections on the convergence of productivity in the United States and Europe, which essentially stopped in the 1990s. It argues that the barriers preventing further convergence in the early 1990s were removed subsequently. But since then trends in productivity growth have been importantly affected by the advent of the New Economy, which poses further challenges for Europe. Without additional reform of European labor markets, financial markets, and university systems, we may be on the eve of another era of persistent divergence.
