We examine a little-known restriction on high-skill immigration to the United States, the Exchange Visitor Skills List. This List mandates that to become eligible for long-term status in the U.S., certain high-skill visitors must reside in their home countries for two years after participation...

Which types of human capital influence the adoption of advanced technologies? We study the skill-biased adoption of information and communication technologies (ICT) across two waves in the UK. Specifically, we compare the "new wave" of cloud and machine learning / AI technologies during the...

In the presence of markup differences, externalities and other social considerations, the equilibrium direction of innovation can be systematically distorted. This paper builds a simple model of endogenous technology, which generalizes existing comparative static results and characterizes...

We study the impact of global expansions in mobile internet access between 2000 and 2018 on student outcomes. We link geospatial data on the rollout of 3G mobile technology with over 2.5 million student test scores from 82 countries. Our findings indicate that the introduction of 3G coverage...

Cross-country variation in effective retirement age is usually attributed to institutional differences that affect individuals’ incentives to retire. This paper suggests a different approach to explain this variation. Since working individuals in different occupations naturally retire at...

We study how occupations shape individual and aggregate retirement behavior. First, we document large differences in individual retirement ages across occupations in U.S. data. We then show that retirement behavior among European workers is strongly correlated with U.S. occupational retirement...

This research explores the origins of observed differences in time preference across countries and regions. Exploiting a natural experiment associated with the expansion of suitable crops for cultivation in the course of the Columbian Exchange, the research establishes that pre-industrial...

The paper extends the findings of Coe and Helpman (1995) model of R&D spillovers by considering foreign direct investment (FDI) as a channel for knowl- edge spillovers in addition to imports. Deeper insights on the issue are provided by examining inter-relationship between knowledge spillovers...

Skill-biased technical change has occupied empirical economists for much of the 90s. However, the empirical literature has not progressed much beyond observing a positive correlation between technology indicators and demand shifts. Two hypotheses on the root causes of skill biases in technical...
