Since gaining independence in 1957, Ghana has significantly increased its economic ties with the global community through trade liberalization policies. However, this integration has profoundly affected the environment, particularly in utilizing natural resources, and has subsequently impacted...

A rapidly growing literature has shown that market concentration among domestic firms has increased in the United States over the last three decades. Using confidential census data for the manufacturing sector, we show that typical measures of concentration, once adjusted for sales by foreign...

This study explores the nexus of digitalization, formalization, and global value chain (GVC) participation, providing critical insights into inclusive growth. Despite the importance of the nexus, common notions regarding the positive effects of digitalization on enterprise formalization and GVC...

Structural quantitative work in international economics typically models trade costs as a log-linear function of exogenous trade-policy variables. We propose a structural approach that allows for a nonparametric relationship and for treating tariff and nontariff trade-policy variables as...

Economy-wide shocks affect demand, supply, and intermediary sectors simultaneously. We dissect the impact of the Covid-19 pandemic on international trade by combining information from customs records, smartphone-based human mobility, and container ship port calls. We find that local disruptions...

This paper evaluates the effects of sanctions on Russia between 2014 and 2019 and the resulting countersanctions. We estimate their impact on trade in a gravity framework, allowing for treatment heterogeneity among pairs and sectors, and use the estimated elasticities in a general equilibrium...

International cooperation is at the core of multilateral climate policy. How is its effectiveness harmed by individual countries not participating in the global mitigation effort? We use a multi-sector structural trade model with carbon emissions from production and a constant elasticity of...

This paper studies the dynamics of importer–exporter connections when importers source inputs from multiple exporters. I first develop a trade model in which heterogeneous importers invest in expanding the set of potential exporters they know and from which they can source. The model delivers...

Services account for one-third of global trade, yet little is known about the impact of trade restrictions on services trade. To make progress in this area, it is crucial to understand through which Modes services are traded (cross-border, movement of people, foreign investment or consumption...

Using firm-level data on production and trade from Denmark, we document that firms frequently employ a strategy of entering new export markets with Carry-Along Trade (CAT), i.e., with products manufactured by other firms. This strategy is surprising because, empirically, CAT products have below...
