This paper compares the wages of workers inside the United States to the wages of observably identical workers outside the United States-controlling for country of birth, country of education, years of education, work experience, sex, and rural-urban residence. This is made possible by new and...

How many immigrants with less than university education, for a given immigration quota, maximise economic output? The answer is zero in the canonical model of the labour market, where the marginal product of a university-educated immigrant is always higher. We build an alternative model in which...

We estimate the quot;place premiumquot;-the wage gain that accrues to foreign workers who arrive to work in the United States. First, we estimate the predicted, purchasing-power adjusted wages of people inside and outside the United States who are otherwise observably identical-with the same...

Countries restrict the overall extent of international travel and migration to balance the expected costs and benefits of mobility. Given the ever-present threat of new, future pandemics, how should permanent restrictions on mobility respond? A simple theoretical framework predicts that reduced...

Despite an enormous literature that has analyzed the comparative experiences of Latin America and Asia in post-World War II trade policy, almost no attention has been paid to the comparative experience prior to the wars. Even a cursory look at the best available empirical evidence reveals...

This paper uses a new database to establish a key finding: high tariffs were associated with fast growth before World War II, while associated with slow growth thereafter. The paper offers some explanations for the sign switch by controlling for novel measures of the changing world economic...

This paper uses a new database to establish two findings covering the first globalization boom before World War I, the second since World War II, and the autarkic interlude in between. First, there is strong evidence supporting a Tariff-Growth Paradox: protection was associated with fast growth...

A decade has passed since Robert Lucas asked why capital does not flow from rich to poor countries. Lucas used a contemporary example to illustrate his Paradox, the very modest flow of capital from the United States to India during the second great global capital market boom, after 1970. Had he...
