Purpose This paper assesses the differences in the use of wine, as a consumed food substance, in the formulation of Portugal and Hungary’s cultural foreign policies between 2010 and 2022. By comparing the degrees of effectiveness of these two traditional wine-making countries’ approaches in...

The European Union's goal of carbon neutrality by 2050 requires a major reduction in natural gas use for residential heating. However, gas grid equipment, amortized over 45 years in most countries, risks becoming stranded assets. The literature suggests that regulatory shocks could justify...

We study the causal effect of country-specific democratic regime change on bilateral trade flows, extending structural gravity empirics to 'heterogeneous gravity' estimated at the country-pair level. Our difference-in-differences implementation accounts for selection into regime change,...

In 1975, a federal court ordered the desegregation of public schools in Jefferson County, KY. In order to approximately equalize the share of minorities across schools, students were assigned to a busing schedule that depended on the first letter of their last name. We use the resulting...

In response to the challenges posed by an increasingly decentralized energy system characterized by a high penetration of renewable energy sources, grid operators are experiencing heightened pressure to effectively manage grid congestion. Concurrently, both the European Union as well as the...

Most analyses of the economic relationship between two countries focus on bilateral trade relations and resource flows. The approach here is different, in that it aims to identify the relative weight of selected partners and their capacity to influence the productive structure in Brazil. Two...

We use the geometric representation of factor models to represent the factor loading structure by sets corresponding to unit-specific non-zero loadings. We formulate global and local, rotational identification conditions based on set conditions. We propose two algorithms to efficiently evaluate...
