With endogenous skills and given technology, labor market integration necessarily lowers welfare of the left-behind in a poor sending country, even if all agents face identical emigration probabilities. This is in sharp contrast to the case of exogenous skill supply.

In this paper we set up a simple theoretical framework to study the possible source country effects of skilled labor emigration. We show that for given technologies, labor market integration necessarily lowers GDP per capita in a poor source country of emigration, because it distorts the...

In this paper we set up a simple theoretical framework to study the possible source country effects of skilled labor emigration from developing countries. We show that for given technologies, labor market integration necessarily lowers GDP per capita in a poor source country of emigration,...

A country’s carbon footprint refers to the CO₂ emissions caused by domestic absorptionactivities. Trade in goods drives a wedge between the footprint and local emissions. Weprovide a panel database on carbon footprints and carbon net trade. Using a differencesin-differences IV estimation...

The carbon footprint of a country refers to the flow of CO2 emissions caused by domestic absorption (i.e., consumption and investment) activities. Trade in goods drives a wedge between the footprint and domestic emissions. We provide a new panel database on carbon footprints and carbon net...

The Kyoto Protocol's success or failure should be evaluated against the unobserved counterfactual of no treatment. This requires instrumental variables. We find that countries' membership in the International Criminal Court (ICC) predicts Kyoto ratification in a panel model. Both multilateral...

Does trade openness cause higher GDP per capita? Since the seminal instrumental variables (IV) estimates of Frankel and Romer [F&R](1999) important doubts have surfaced. Is the correlation spurious and driven by omitted geographical and institutional variables? In this paper, we generalize F&R's...
