Climate policies vary widely across countries, with some countries imposing stringent emissions policies and others doing very little. When climate policies vary across countries, energy-intensive industries have an incentive to relocate to places with few or no emissions restrictions, an effect...

The paper discusses the effects of the corporate tax on local R&D expenditures by multinational enterprises (MNEs) when income from intellectual property (IP) may or may not benefit from a special IP regime. Our model shows that an increase of the standard corporate tax may have positive effects...

This paper develops a dynamic programming method when the one-stage deviation principle in the sense of mechanism design literature doesn’t hold. The commonly used dynamic programming method is valid only if the one-stage deviation principle in the sense of mechanism design literature is...

We propose a new method for solving high-dimensional dynamic programming problems and recursive competitive equilibria with a large (but finite) number of heterogeneous agents using deep learning. The „curse of dimensionality“ is avoided due to four complementary techniques: (1) exploiting...

How much and when should we limit economic and social activity to ensure that the health-care system is not overwhelmed during an epidemic? We study a setting where ICU resources are constrained while suppression is costly (e.g., limiting economic interaction). Providing a fully analytical...

Decisions under risk are often multidimensional, where the preferences of the decision maker depend on several attributes. For example, an individual might be concerned about both her level of wealth and the condition of her health. Many times the signs of successive cross derivatives of a...

Prior studies show that taxes matter for the residential locations of high-income earners. But, states raise a significant share of revenue from nonresidents. Using variation in state tax rates, we provide causal evidence on the effect of the net-of-tax rate on the location of labor supply for...

This paper exploits a short-lived cooperation program between the U.S.S.R. and China, which led to the construction of 156 "Million-Rouble plants" in the 1950s. We isolate exogenous variation in location decisions due to the relative position of allied and enemy airbases and study the long-run...

The structure of a multinational firm, that is how its affiliates relate to one another, is critical for understanding where multinationals locate, how policy affects them, and their resilience to localized shocks. Here, we review the two main structures: horizontal investments which replicate...

This paper defines isomorphism for network formation that is not mathematically isomorphic. Once the pattern of network formation is characterized, one can test for (i) location fixed effects, (ii) heterogeneity, (iii) private information allowing for long-term contracts. The paper provides...
