From 1997 through early 2003, the United Nations Oil for Food Program allowed Iraq to export oil in exchange for humanitarian supplies. We measure the extent to which this program was corrupted by Iraq's attempts to deliberately set the price of its oil below market prices in an effort to...

Real estate agents in the US typically charge a 6 percent commission, regardless of the price of the house sold. As a consequence, the commission fee from selling a house will differ dramatically across cities depending on the average price of housing, although the effort necessary to match...

We quantify the amount of spatial misallocation of labor across US cities and its aggregate costs. Misallocation arises because high productivity cities like New York and the San Francisco Bay Area have adopted stringent restrictions to new housing supply, effectively limiting the number of...

We estimate direct and indirect effects of total factor productivity growth in manufacturing on US workers' earnings, housing costs, and purchasing power. Drawing on four alternative instrumental variables, we consistently find that when a city experiences productivity gains in manufacturing,...

In most countries, average wages tend to be higher in larger cities. In this paper, we focus on the role played by the matching of workers to firms in explaining geographical wage differences. Using rich administrative German data for 1985-2014, we show that wages in large cities are higher not...

Italy and Germany have similar geographical differences in productivity – North more productive than South in Italy; West more productive than East in Germany – but have adopted different models of wage bargaining. Italy sets wages based on nationwide contracts that allow for limited local...

We estimate the effect of high school graduation on participation in criminal activity accounting for endogeneity of schooling. We begin by analyzing the effect of high school graduation on incarceration using Census data. Instrumental variable estimates using changes in state compulsory...

Poor and uneducated patients may not know what health care is desirable and, if fully insured, have little incentive to minimize the costs of their care. Partly in response to these concerns, most states have moved a substantial portion of their Medicaid caseloads out of traditional competitive...

I assess the magnitude of human capital spillovers in US cities by estimating plant-level production functions. I use a unique firm worker matched dataset, obtained by combining the Census of Manufacturers with the Census of Population. After controlling for a plant's own human capital, plant...

Traditional models of politician behavior predict complete or partial policy convergence, whereby electoral competition compels partisan politicians to choose positions more moderate than their most-preferred policies. Alternatively, if politicians cannot overcome the inability to make binding...
