Official data on output and employment … data reduce the magnitude of the post-1973 productivity slowdown in transportation MFP growth from a previously reported 2 … control, and highways, do not change appreciably the pattern of postwar MFP growth in transportation …

of the Tiebout hypothesis using historical variation in mobility costs. Our extension of the Tiebout model to incorporate … such costs yields the following comparative statics: as mobility costs fall, the heterogeneity across communities of … mobility costs have fallen over time, a natural test of the Tiebout hypothesis is to take these predictions to the data here …

Recent years have seen an unprecedented growth and geographic dispersion in international student mobility. In this … mobility - the human capital model and the migration model - across traditional and emerging destinations. Our findings suggest …

This study quantifies the effect of state reopening policies on daily mobility, travel, and mixing behavior during the … different states. We quantify the increase in mobility patterns during the reopening phase by a broad range of cell …-device-based metrics. Soon (four days) after reopening, we observe a 6% to 8% mobility increase. In addition, we find that temperature and …

This short note constructs Mobility Zones to facilitate the discussion on the geographic extent of individual mobility … restrictions to control the spread of Covid-19. Mobility Zones are disjoint sets of counties where a given level of individual … mobility directly or indirectly connects all counties within each set. I compute Mobility Zones for the United States and each …

We quantify the causal impact of human mobility restrictions, particularly the lockdown of the city of Wuhan on January …-in-differences (DID) estimations to disentangle the lockdown effect on human mobility reductions from other confounding effects including …
