We show experimentally that fairness concerns may have a decisive impact on the actual and optimal choice of contracts in a moral hazard context. Bonus contracts that offer a voluntary and unenforceable bonus for satisfactory performance provide powerful incentives and are superior to explicit...

We construct spatially-weighted indices of the geographic concentration of U.S. manufacturing industries during the period 1880 to 1997 using data from the Census of Manufactures and Bureau of Labor Statistics. Several important new results emerge from this exercise. First, we find that average...

Do factor endowments explain serfdom? Domar (1970) conjectured that high land-labor ratios caused serfdom by increasing incentives to coerce labor. But historical evidence is mixed and quantitative analyses are lacking. Using the Acemoglu-Wolitzky (2011) framework and controlling for political...

We investigate the role of industrial structure in labor productivity growth in U.S. cities between 1880 and 1930 using a new dataset constructed from the Census of Manufactures. We find that increases in specialization were associated with faster productivity growth but that diversity only had...

We re-examine the long-run geographical development of U.S. manufacturing industries using recent advances in spatial concentration measures. We construct spatially-weighted indices of the geographical concentration of U.S. manufacturing industries during the period 1880 to 1997 using data from...

The reasons for the famous agrarian unrest in the United States between 1870 and 1900 remain debated. We argue that they are, at least in part, consistent with a simple economic explanation. Falling transportation costs allowed for the extension of the frontier, where farmers received the world...
