Geopolitical conflicts generate macroeconomic spillovers that extend beyond directly affected countries through trade and commodity linkages. This paper quantifies these effects for Germany, France, Italy, and Spain using a monthly Trade-Related Conflict Exposure (TRCE) index for 2009–2023...

This paper studies how and why anti-Irish sentiment in 19th century England spills over onto jury decisions at London’s Old Bailey Central Criminal Court. We classify the (perceived) ethnicity of courtroom participants according to whether they have distinctly Irish or English surnames based...

We digitize and analyze the near-universe of National Socialist German Workers’ Party (NSDAP) membership records and link them to population and industrial censuses. Four findings emerge. First, as the party expanded, its membership came to resemble the broader population more closely in...

Migration is a central feature of development and climate resilience. Yet, it is increasingly framed as a pathway through which climate may affect conflict, despite fragmented and mixed evidence. We systematically review findings from 20 statistical studies to examine: When and how do...

We investigate the causal relationship between inventor migration and regional innovation in the context of the large-scale migration shock from East to West Germany between World War II and the construction of the Berlin Wall in 1961. Leveraging a newly constructed, century-spanning dataset on...

We develop a simple two-period principal-agent model in which a present-biased government, the agent, chooses public investment levels given a deficit rule imposed by the principal. The principal sets a deficit cap to curb current debt-financed consumption. In doing so, it also reduces long-term...

While Equity Crowdfunding (ECF) platforms are a virtual space for raising funds, geography remains relevant. To determine how location matters for entrepreneurs using equity crowdfunding (ECF), we analyze the spatial distribution of successful ECF campaigns and the spatial relationship between...

This paper investigates partial cartels, which laboratory studies have neglected despite their empirical prevalence. We conduct two laboratory experiments to understand how they function compared to all-inclusive cartels and respond to antitrust policies. First, we compare partial cartel...

We examine how gender shapes managers’ decisions regarding on-the-job training using a discrete choice experiment embedded in a representative survey of German firms. While previous research on training has focused on employees’ demand for it, we make a contribution by studying firms’...

While an influential body of economic literature shows that allowing for communication between firms increases collusion in oligopolies, so far we have only anecdotal evidence on the precise communication content that helps firms to coordinate their behavior. In this paper, we conduct a...
