This paper uses spatial differencing to estimate parameters in sample selection models with unobserved heterogeneity. We show that under the assumption of smooth changes across the space of unobserved site-specific heterogeneity and selection probability, key parameters of a sample selection...

In this paper, we analyze the International Great Depression in the US and Western Europe using the business cycle accounting method a la Chari, Kehoe and McGrattan (CKM 2007). We extend the business cycle accounting model by incorporating endogenous factor utilization which turns out to be an...

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...
