I study knowledge spillovers, positive externalities that augment the information set of an economic agent, and reviews the evidence on such spillovers in the context of international economic transactions. Even though spillovers are by their very nature difficult to identify, over recent...

Free trade or preferential trade areas (PTAs) allow importers who belong to the area to export to each other while paying zero or preferential tariffs as long as Rules of Origin (ROOs) are met. Meeting them is costly not only in terms of production costs but also in terms of documentation costs....

Two central insights from the Schumpeterian approach to innovation and growth are that the pace of innovation is endogenously determined by the expectation of future profits and that growth is inherently a process of creative destruction. As international trade is a key determinant of firm...

We analyze a two-country model of trade in both legitimate and counterfeit products. Domestic firms own trademarks and establish reputations for delivering high-quality products in a steady-state equilibrium. Foreign suppliers export legitimate low-quality merchandise and counterfeits of...

Previous work by Dixit and Woodland on the effect of inter-country factor endowment differences on goods trade is extended to include simultaneous factor trade and goods trade. The goods trade pattern with factor trade is compared to that without factor trade. It is for instance shown that goods...

One of the most successful empirical relationships in international trade is the gravity equation, which relates bilateral trade flows between an origin and destination to bilateral trade frictions, origin characteristics, and destination characteristics. A key decision for researchers in...

Common wisdom dictates that uncertainty impedes trade--we show that uncertainty can fuel more trade in a simple general equilibrium trade model with information frictions. In equilibrium, increases in uncertainty increase both the mean and the variance in returns to exporting implying that trade...

This paper presents new evidence on international trade and worker outcomes. It examines a big world event that produced an unprecedentedly large shock to the UK exchange rate. In the 24 hours in June 2016 during which the UK electorate unexpectedly voted to leave the European Union, the value...

The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank's Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50% of variation in exports is along the extensive...

Almost Ideal gravity associates zero trade flows with variable and fixed trade cost variation in a flexible demand system. Latent trade shares between non-partners are inferred from the Tobit estimator applied to trade among 75 countries and 25 sectors in 2006. Latent Trade Bias (LTB) is the...
