We study the geographic incidence and efficiency of an income tax by estimating a spatial equilibrium model with heterogeneous workers. The US shifts households out high-productivity cities, leading to locational inefficiency 0.25 percent output. Removing distortions increases inequality because more educated are mobile own larger shares land. Flattening schedule, or introducing cost-of-living ...

This paper studies how birth town migration networks affected long-run location decisions during historical US episodes. We develop a new method to estimate the strength of for each receiving and sending location. Our estimates imply that when one randomly chosen African American moved from Southern destination county, then 1.9 additional Black migrants made same move on average. For White Grea...

This paper measures excess labor supply in equilibrium. We induce hiring shocks—which employ 24 percent of the force external month-long jobs—in Indian local markets. In peak months, wages increase instantaneously and aggregate employment declines. lean consistent with severe rationing, are unchanged, positive spillovers on remaining workers, indicating that over a quarter is rationed. At least...

BACKGROUND Plasmodium falciparum merozoite surface protein 5 (PfMSP5) is an attractive blood stage vaccine candidate because it is both exposed to the immune system and well conserved. To evaluate its interest, we investigated the association of anti-PfMSP5 IgG levels, in the context of responses to two other conserved Ags PfMSP1p19 and R23, with protection from clinical episodes of malaria in ...

Many countries shift substantial public resources across jurisdictions to mitigate spatial economic disparities. We use a general equilibrium model with multiple asymmetric regions, labor mobility, and costly trade carve out the aggregate implications of fiscal transfers. Calibrating for Germany, we find that transfers indeed deliver smaller disparities regions. This comes at cost lower nationa...

Empirical researchers often combine multiple instrumental variables (IVs) for a single treatment using two-stage least squares (2SLS). When effects are heterogeneous, common justification including IVs is that the 2SLS estimand can be given causal interpretation as positively weighted average of local (LATEs). This requires well-known monotonicity condition. However, we show with more than one ...

New Directions for Residential Mobility Research: Linking Lives through Time and Space While researchers are increasingly reconceptualising international migration, less interest is being shown in rethinking the geographies of short-distance residential mobility and immobility. Short-distance moves are crucial for the structuration of everyday life, the operation of housing and labour markets a...
