Multinational firms (MNEs) accounted for 42 percent of US manufacturing employment, 87 percent of US imports, and 84 of US exports in 2007. Despite their disproportionate share of global trade, MNEs' input sourcing and final-good production decisions are often studied separately. Using newly...

We introduce a general quantifiable framework to study the location decisions of multinational firms. In the model, firms choose in which locations to pay the fixed costs of setting up production, taking into account potential complementarities among production locations. The firm's location...

Many developing countries would like to increase the share of modern or formal sectors in their employment. One way to accomplish this goal may be to encourage the entrance of foreign firms. They are typically relatively large, with high productivity and good access to foreign markets, and might...

We evaluate the 2017 Tax Cuts and Jobs Act. Combining reduced-form estimates from tax data with a global investment model, we estimate responses, identify parameters, and conduct counterfactuals. Domestic investment of firms with the mean tax change increases 20% versus a no-change baseline. Due...

Despite competition concerns over the increasing dominance of global corporations, many argue that productivity spillovers from multinationals to domestic firms justify pro- FDI policies. For the first time, we use firm-to-firm transaction data in a developed country to examine the impact of...

Climate-related risks have increased in recent decades, both in terms of the frequency of extreme weather events (physical risk) and implementation of climate-change mitigation policies (transition risk). This paper explores whether multinational firms react to such risks by altering their...

Applied general-equilibrium (AGE) models have often made compromises to circumvent difficult modeling problems. One of these is avoiding endogenous zeros, ruling out important questions. Traditional perfect competition models: when do technologies or trade links switch from active to inactive or...

Increasing attention has been given to the impact of third countries on outbound FDI to a given host country. Here, we consider potential third-country effects on inbound FDI. A simple model suggests two sources of such effects on a country's inbound FDI. First, it will tend to receive more FDI...

Firms in developing countries cite credit constraints as one of their primary obstacles to investment. Direct foreign investment, by bringing in scarce capital, may ease domestic firms' credit constraints. Alternatively, if foreign firms borrow heavily from domestic banks, they may exacerbate...

The rise of artificial intelligence (AI) and of cross-border restrictions on data flows has created a host of new questions and related policy dilemmas. This paper addresses two questions: How is digital service trade shaped by (1) AI algorithms and (2) by the interplay between AI algorithms and...
