We discuss the impacts of the Russian invasion on Ukrainian science. Using newly collected data, we show that the war has already had significant effects on science in Ukraine: research papers produced by Ukrainian scientists declined by about 10%, approximately 5% of the most prolific...

In this paper we deliver first causal evidence on the relationship between immigrant host country language proficiency and homeownership. Using an instrumental variable strategy, we find a substantial positive impact of language skills on the propensity to own a home and the quality of housing....

The COVID-19 pandemic has led to a changing environment for transnational migrant start-ups. These changes have posed many challenges concerning altering strategic behaviour and approaches to driving business. We explored transnational migrant start-ups' embeddedness in translocal...

Using a structural life-cycle model, we quantify the long-term impact of school closures during the Corona crisis on children affected at different ages and coming from households with different parental characteristics. In the model, public investment through schooling is combined with parental...

We introduce two types of effort into an otherwise standard labor search model to examine indeterminacy and sunspot equilibria. Variable labor effort gives rise to increasing returns to hours in production. This makes workers more valuable and contributes to self-fulfilling profit expectations,...

This research develops an expanded unified growth theory that incorporates the endogenous accumulation of physical capital, population, human capital, and technology. The model incorporates a complementarity between physical capital and human capital and can be extended to a multi-country...
