The Interaction and Sequencing of Policy Reforms
In what order should a developing country adopt policy reforms? Do some policies complement each other? Do others substitute for each other? To address these questions, we develop a two-country dynamic general equilibrium model with entry and exit of firms that are monopolistic competitors. Distortions in the model include barriers to entry of firms, barriers to international trade, and barriers to contract enforcement. We find that a reform that reduces one of these distortions has different effects depending on the other distortions present. In particular, reforms to trade barriers and ...

What will happen when foreigners stop lending to the United States?
Since the early 1990s, the United States has borrowed heavily from its trading partners. This paper presents an analysis of the impact of an end to this borrowing, an end that could occur suddenly or gradually.

Global imbalances and structural change in the United States
Since the early 1990s, as the United States has borrowed from the rest of the world, employment in U.S. goods-producing sectors has fallen. Using a dynamic general equilibrium model, we find that rapid productivity growth in goods production, not U.S. borrowing, has been the most important driver of the decline in goods-sector employment. As the United States repays its debt, its trade balance will reverse, but goods-sector employment will continue to fall. A sudden stop in foreign lending in 2015?2016 would cause a sharp trade balance reversal and painful reallocation across sectors, but ...

New exporter dynamics
Models in which heterogeneous plants face sunk export entry costs are standard tools in the international trade literature. How well do these models account for the observed dynamics of new exporters? We document that new exporters initially export small amounts and ? conditional on continuing in the export market ? grow gradually over several years. New exporters are most likely to exit the export market in their first few years. We construct a dynamic discrete choice model of exporting and find that the standard model cannot replicate the behavior of new exporters: New exporters grow too ...

Offshore Profit Shifting and Domestic Productivity Measurement
Official statistics display a significant slowdown in U.S. aggregate productivity growth that begins in 2004. We show how offshore profit shifting by U.S. multinational enterprises affects GDP and, thus, productivity measurement. Under international statistical guidelines, profit shifting causes part of U.S. production generated by multinationals to be excluded from official measures of U.S. production. Profit shifting has increased significantly since the mid-1990s, resulting in lower measures of U.S. aggregate productivity growth. We construct an alternative measure of value added that ...

The Opportunity Costs of Entrepreneurs in International Trade
We show that a trade model with an exogenous set of heterogeneous firms with fixed operating costs has the same aggregate outcomes as a span-of-control model. Fixed costs in the heterogeneous-firm model are entrepreneurs' forgone wage in the span-of-control model.

Firm Entry and Exit and Aggregate Growth
Using data from Chile and Korea, we find that a larger fraction of aggregate productivity growth is due to firm entry and exit during fast-growth episodes compared to slow-growth episodes. Studies of other countries confirm this empirical relationship. We develop a model of endogenous firm entry and exit based on Hopenhayn (1992). Firms enter with efficiencies drawn from a distribution whose mean grows over time. After entering, a firm?s efficiency grows with age. In the calibrated model, reducing entry costs or barriers to technology adoption generates the pattern we document in the data. ...

Trade adjustment dynamics and the welfare gains from trade
We build a micro-founded two-country dynamic general equilibrium model in which trade responds more to a cut in tariffs in the long run than in the short run. The model introduces a time element to the fixed-variable cost trade-off in a heterogeneous producer trade model. Thus, the dynamics of aggregate trade adjustment arise from producer-level decisions to invest in lowering their future variable export costs. The model is calibrated to match salient features of new exporter growth and provides a new estimate of the exporting technology. At the micro level, we find that new exporters ...

Are shocks to the terms of trade shocks to productivity?
International trade is frequently thought of as a production technology in which the inputs are> exports and the outputs are imports. Exports are transformed into imports at the rate of the price> of exports relative to the price of imports: the reciprocal of the terms of trade. Cast this way, a> change in the terms of trade acts as a productivity shock. Or does it? In this paper, we show that> this line of reasoning cannot work in standard models. Starting with a simple model and then> generalizing, we show that changes in the terms of trade have no first-order effect on> productivity when ...

How important is the new goods margin in international trade?
We propose a methodology for studying changes in bilateral trade due to countries exporting goods that they did not export previously or exported only in small quantities. Applying this methodology to country pairs that undergo trade liberalization and to pairs in which one of the countries undergoes significant structural transformation, we find large increases on this extensive?or new goods?margin. Looking at country pairs with no major trade policy change or structural change, however, we find little or no increases on the extensive margin. Studying time series on trade by commodity, we ...
