We use the granular model of international trade developed in Gaubert and Itskhoki (2020) to study the rationale and implications of three types of government interventions typically targeted at large individual firms -- antitrust, trade and industrial policies. We find that in antitrust...

In this paper we provide an integrative treatment of the welfare effects of trade and industrial policy under oligopoly, and characterize qualitatively the form that optimal intervention takes under a variety of assumptions about the number of firms, their conjectures about the response of their...

This paper examines how industrial policy - specifically tariff liberalization and tax subsidies - affects the magnitude and direction of FDI spillovers. We examine these spillover effects across the diverse ownership structure of China's manufacturing sector. Using this approach, we control for...

Several efficiency wage theories of wage determination have the property that identical workers are more productive in high wage industries and that the promotion of employment in high wage industries can increase GDP (and some measures of welfare). I argue that while policies to favor high wage...

There has been an increased interest in the efficacy of industrial policy. We show that policy design for vertically-related industries hinges on the nature of market interactions as well as technological linkages. Using a model in which final-good producers realize productivity gains from...

Using a panel data set of county-level employment in machinery, electrical machinery, primary metals, transportation, and instruments, this paper analyzes the role of dynamic externalities for individual industries. Key issues examined include the role of externalities from own industry...

We consider a model with several regions whose technological ability and factor endowments are identical and in which transport costs between regions are non-negligible. Nonetheless, certain goods are sometimes produced by multiple firms all of which are located in the same region. These goods...

This paper models an economy in which it is costly to move resources between the tradeable and nontradeable sectors. The economy is subject to capital flows that are unpredictable and are perceived as having only limited persistence. The model shows that both the fact that capital flows are...
