Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....

Do firms in developing countries shift trade towards developed economies as a result of high economic growth? The matched customs-manufacturing firm data used in this study confront this hypothesized link with empirical evidence. Our analysis reveals a rising low-income country trade share...

We set up a model of offshoring with heterogeneous producers that captures two empirical regularities of German offshoring firms. There is selection of larger, more productive firms into offshoring. However, the selection is not sharp, and offshoring and non-offshoring firms coexist over a wide...

This paper studies regional treatment effects of infrastructure projects on economic growth, employment and intermodal transport volumes. The recent Belt and Road Initiative provides an experiment that can be evaluated using matching econometrics. Our results show that the establishment of a new...

In the beginning of the COVID-19 pandemic, governments had to rely on Non-Pharmaceutical Interventions in their struggle against the spread of the virus. The stringency of the lockdowns differed across space and time as governments had to adjust their strategy dynamically to the country-specific...

This paper develops an approach that allows constructing regional proxies of government effectiveness at a highly dis-aggregated level. Our idea builds on the well documented interdependence between institutions and exports, which allows estimating the latent government effectiveness using...

We propose a model which uses the Bitcoin/US dollar exchange rate to predict the computing power of the Bitcoin network. We show that free entry places an upper-bound on mining revenues and we devise a structural framework to measure its value. Calibrating the model's parameters allows us to...

Does trade openness cause higher GDP per capita? Since the seminal instrumental variables (IV) estimates of Frankel and Romer [F&R](1999) important doubts have surfaced. Is the correlation spurious and driven by omitted geographical and institutional variables? In this paper, we generalize F&R's...

This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodriguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country's share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical testing,...
