We explore the effect of historical ethnic borders on contemporary conflict in Africa. We document that both the intensive and extensive margins of contemporary conflict are higher close to historical ethnic borders. Exploiting variations across artificial regions within an ethnicity's...

We study the role of proximity to historical ethnic borders in determining individual land ownership in Sub-Saharan Africa. Following an instrumental variable strategy, we document that individuals have a lower likelihood of owning land near historical ethnic borders. In particular, the...

This paper presents a theoretical conceptualization of the data economy that motivates more access to data for scientific research. It defines the semicircular flow of the data economy as analogous to the traditional circular flow of the economy. Knowledge extraction from large, inter-connected...

Concerns about the welfare of working children has over time produced a wide range of international and national interventions in the child labor market, culminating most recently in a commitment to eradicate the worst forms of child work via the attainment of target 8.7 of the Sustainable...

Traditional gender norms can restrict independent migration by women, thus preventing them from taking advantage of economic opportunities in urban non-agricultural industries. However, women may be able to circumvent such restrictions by using marriage to engage in long-distance migration - if...

This paper studies whether research universities can boost regional economic development through an exogenous shock of a forced relocation of a research university in China. We analyze the development in the treated regions compared with a set of control regions that are created using the...

The Coronavirus Disease 2019 (COVID-19) pandemic is bringing about once-in-a-century changes to human society. Three key properties escalate the COVID-19 pandemic into a syndemic. To address this triple crisis, we discuss the importance of integrating early, targeted and coordinated public...

This study investigates why the strong form of the spatial equilibrium is weakly supported in the literature. Using a discrete choice model, it shows that the strong form of the spatial equilibrium is rarely observed because workers are imperfectly mobile from the perspective of researchers....
