This paper studies the macroeconomic effects of an inflow of low-skilled workers into an economy where there is capital accumulation, endogenous labour supply and heterogeneous workers. We find substantial dynamic effects, with adjustments that resemble those triggered by a sudden disruption of...

This Paper explores the relationship between environmental protection and international capital movements, when tax policy is endogenous (through voting).

The long-run price elasticity of demand for credit is a key parameter for intertemporal modeling, policy levers, and lending practice. We use randomized interest rates, offered across 80 regions by Mexico’s largest microlender, to identify a 29-month dollars-borrowed elasticity of -1.9. This...

How do firms' sales interact across markets? Are foreign and domestic sales complements or substitutes? Using a large French firm-level database that combines balance-sheet and product-destination-specific export information over the period 1995-2001, we study the interconnections between...
