The Black Death was the largest demographic shock in European history. We review the evidence for the origins, spread, and mortality of the disease. We document that it was a plausibly exogenous shock to the European economy and trace out its aggregate and local impacts in both the short run and the long run. The initial effect of the plague was highly disruptive. Wages and per capita income rose. But, in the long run, this rise was only sustained in some parts of Europe. The other indirect long-run effects of the Black Death are associated with the growth of Europe relative to the rest of the world, especially Asia and the Middle East (the Great Divergence), a shift in the economic geography of Europe toward the northwest (the Little Divergence), the demise of serfdom in western Europe, a decline in the authority of religious institutions, and the emergence of stronger states. Finally, avenues for future research are laid out.

This paper critically surveys the growing literature on the policy choices of local governments. First, we identify various reasons for local government policy interactions, including fiscal competition, bidding for firms, yardstick competition, expenditure spillovers, and Tiebout sorting. We discuss theoretically what parameters should be estimated to determine the reason for competition among local governments. We emphasize how the policy outcomes emerging from this competition are affected by the presence of constraints imposed by higher-level governments. Second, we integrate theoretical and empirical analyses on the effects of fiscal decentralization on mobility, spillovers, fiscal externalities, economic outcomes, and distributional issues. Third, we identify key issues that arise in the empirical estimation of strategic interactions among local governments and highlight recent quasi-experimental evidence that has attempted to identify the mechanism at work. Finally, a synthesis model, containing multiple mechanisms and fiscal instruments, resolves some puzzles and provides guidance for future research.
