This paper develops a new model with heterogeneous firms under perfect competition in a Heckscher-Ohlin-Samuelson setting. We show that trade need not make selection in the comparative advantage sector stricter as suggested by earlier work. Selection is driven by the capital intensity in entry...

We measure export participation rates in the U.S. manufacturing sector using a new administrative dataset and compare them to participation rates constructed from the commonly used Census of Manufacturers (CM). Both at the establishment and firm level export participation rates are near 40...

Conventional wisdom holds that monetary policy in emerging economies is procyclical, unlike in advanced economies. Using a large sample of countries from the mid-1990s onwards, we show that the conduct of monetary policy is not fundamentally different across these two groups of countries....

This article describes methods used in the field of spatial economics that combine insights from economic theory and evidence from data in order to answer counter- factual questions. I outline a general framework that emphasizes three elements: a specific question to be answered, a set of...

We examine the dynamics of a country's growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, self-interested spending. Surprisingly, government myopia can increase a country's access to external borrowing. In turn, access to borrowing...

We use Chinese customs data to show that unofficial non-tariff barriers were responsible for 50\% of the overall reduction in Chinese imports from the U.S. during the height of the U.S.-China trade war in 2018 and 2019. We infer non-tariff barriers from the change in imports of U.S. products...

Using hand-collected data spanning more than a decade on European banks' sovereign debt portfolios, we show that the trust of residents of a bank's countries of operation in the residents of a potential target country of investment has a positive, statistically significant, and economically...

The relationship between per capita income and a number of pollution indicators has been found to display an inverted U-shaped or downward-sloping pattern. Corruption may affect this relationship in two distinct ways: by raising pollution at given income levels (direct effect) and by reducing...

This review discusses frontier topics in economic geography as they relate to firms and agglomeration economies. We focus on areas where empirical research is scarce but possible. We first outline a conceptual framework for city formation that allows us to contemplate what empiricists might...

We build a model of conflict in which two groups contest a resource and must decide on the optimal allocation of labor between fighting and productive activities. In this setting, a diaspora emanating from one of the two groups can get actively involved in the conflict by transferring financial...
