We study the consequences of protectionism for macroeconomic fluctuations. First, using high-frequency trade policy data, we present fresh evidence on the dynamic effects of temporary trade barriers. Estimates from country-level and panel VARs show that protectionism acts as a supply shock,...

This chapter was prepared for the Handbook of International Economics (Vol. 5) edited by Gita Gopinath, Elhanan Helpman, and Kenneth Rogoff. We provide a review of the recent literature -- both theoretical and empirical -- analyzing the multi-dimensional connections between globalization and...

This paper studies the expansion patterns of the multinational enterprise (MNE) in time and space. Using a long panel of US MNEs, we document that MNE affiliates usually start with sales exclusively to the host market and eventually enter export markets, and that this extensive margin of...

Despite the historic prevalence of industrial policy and its current popularity, few empirical studies directly evaluate its welfare consequences. This paper examines an important industrial policy in China in the 2000s, aiming to propel the country's shipbuilding industry to the largest...

We estimate the impact of the tariffs that U.S. export crops face on farmland rental rates. The estimation of the impact of the localized measure on the rents faces two aggregation problems that lead to identification challenges: a) aggregating tariffs across trading partners to obtain...

Firm size follows Zipf's Law, a very fat-tailed distribution that implies a few large firms account for a disproportionate share of overall economic activity. This distribution of firm size is crucial for evaluating the welfare impact of economic policies such as barriers to entry or trade...

Models dealing with cross-border acquisitions versus greenfield investment usually assume that the entry of a foreign firm into a market has effects on the outputs of all domestic firms in that market, but exit or entry of local firms is not considered. The purpose of this paper is to re-examine...

I develop a new theory of marketing costs and introduce it into a model of trade with product differentiation and firm productivity heterogeneity. In this model, a firm enters a market if it makes profits by reaching a single consumer there and pays an increasing marginal cost to access...

In this paper, we develop a novel theory of cross-border mergers and acquisitions. Firms can choose between different modes of foreign market access: exporting, greenfield FDI, and cross-border M&A. Our theory is based on three key ideas. First is heterogeneity in firms' capabilities. Second,...

We examine entry across 113 national markets in 16 different industries using a comprehensive data set of French manufacturing firms. The data are unique in indicating how much each firm exports to each destination. Looking across all manufacturers: (1) Firms differ substantially in export...
