To reduce funds for Russia's Ukraine invasion, Western governments imposed a price ceiling on Russian seaborne oil exports using Western services. To sell above that ceiling, Russia developed a "shadow fleet" which uses no such services. We use a calibrated model driven by this fleet's expansion...

We examine an open economy’s strategy to reduce its carbon emissions by replacing its consumption of coal—very carbon intensive—with gas—less so. Unlike the standard theoretical approach to carbon leakage, we show that unilateral CO2 reduction policies generate a higher leakage rate in...

This paper uses a survey among students at European universities to explore whether Russia's invasion of Ukraine has affected attitudes toward European integration. Some respondents completed the survey just before Russia's assault on February 24, 2022, and some did so just afterwards, thus...

The COVID-19 pandemic has led to a substantial increase in the prevalence of working from home among white-collar occupations. This can have important implications for the future of the workplace and quality of life. We discuss an additional implication, which we label reverse brain drain: the...

This paper proposes a theory of migration decisions in which cultural traits play a role. Individuals are assumed to value comfort (high wages) and conformity (interactions with individuals who share similar world views). Regions are assumed to differ economically (average wages) and culturally...

We examine an open economy’s strategy to reduce its carbon emissions by replacing its consumption of coal—very carbon intensive—with gas—less so. Unlike the standard analysis of carbon leakage, unilateral carbon-reduction policies with more than one carbon energy source may turn...
