What are the welfare implications of placing restrictions on internal migration? Given externalities in location choices, the answer is ambiguous. This paper empirically examines what is presumably the largest government intervention in internal migration in human history--the Hukou system in...

This paper estimates a theory-guided gravity equation of regional patient ows. In our model, a patient's choice to consult a physician in a particular region depends on a measure of spatial accessibility that accounts for the exact locations of both patients and physicians. Introducing this...

Dieses Working Paper beschreibt die Branchenstruktur von Regionstypen und Regionen in Deutschland. Sein Fokus liegt auf der wirtschaftlichen Spezialisierung ländlicher Räume relativ zur bundesweiten Gesamtwirtschaft. Die Auswertungen wurden im Rahmen des Forschungsvorha-bens „Die räumliche...

This paper studies the persistence of a large, unexpected, and regionally very unevenly distributed population shock, the inflow of eight million ethnic Germans from Eastern Europe to West Germany after World War II. Using detailed census data from 1939 to 1970, we show that the shock had a...

Why do people live, work, and play where they do? How much, why, and between what points do people migrate, temporarily and permanently? These are relatively simple questions, but the answers are much less clear and do not fall neatly into one field of knowledge. Because choices are involved,...

Finding suitable employment in a city is more challenging for married than unmarried migrants. This paper provides empirical evidence that the denser and more diversified labor markets in large cities help alleviate the colocation problem of married couples. Using data from China, we show that...
