From the beginning of the Covid-19 pandemic to late 2021, international immigration flows to the US decreased significantly. We document the timing and the characteristics of these significant changes in flows, their evolution until late 2022 and their geographic and sector distribution. We...

In this paper we examine the causal relationship between formal social insurance and individuals' migration decisions. We exploit a quasi experimental design in rural China, under which county officials were assigned to a group of villages (i.e., treated villages) to serve as village supervisors...

In this paper, we investigate whether or not recent state and federal changes in welfare policy -- the imposition of time-limited benefits, the use of financial sanctions for non-compliance, and the setting of strict work eligibility rules -- affect the migration of low-educated unmarried women....

** Revised version 2005** <p> Using a recently-uncovered data set that describes over 30 federal New Deal spending, loan, and mortgage insurance programs across all U.S. counties from 1933 to 1939, this paper empirically examines the New Deal's impact on inter-county migration from 1930 to 1940. We...</p>

In 1997 GDP per capita in East Germany was 57% of that of West Germany, wage rates were 75% of western levels, and the unemployment rate was at least double the western rate of 7.8%. One would expect that if capital flows and trade in goods failed to bring convergence, labor flows would respond,...

The paper first extends and reconciles recent estimates of the strikingly large effect of national borders on trade patterns. Estimates comparing trade among Canadian provinces with that between Canadian provinces and U.S. states show interprovincial trade in 1988-90 to have been more than...

This paper examines the extent to which differences in welfare generosity across states leads to interstate migration. Using microdata from the National Longitudinal Survey of Youth (NLSY) between 1979 and 1992, we employ a quasi-experimental design that utilizes the categorical eligibility of...

Though the geographic, occupational, and financial mobility of average Americans were important aspects of nineteenth century U.S. economic development, the extent and correlates of this economic mobility have remained open to debate in the absence of individual- level longitudinal data. This...

Do poor economies grow faster than rich ones? This important economic question (which we call [beta]-convergence) is analyzed in this paper using two regional data sets: 47 Prefectures in Japan and 48 States of the U.S.. We find clear evidence of convergence in both countries: poor prefectures...
