Deindustrialization and Industry Polarization
We add to recent evidence on deindustrialization and document a new pattern: increasing industry polarization over time. We assess whether these new features of structural change can be explained by a dynamic open economy model with two primary driving forces, sector-biased productivity growth and sectoral trade integration. We calibrate the model to the same countries used to document our patterns. We find that sector-biased productivity growth is important for deindustrialization by reducing the relative price of manufacturing to services, and sectoral trade integration is important for ...

International Capital Flows: Private Versus Public Flows in Developing and Developed Countries
Empirically, net capital inflows are pro-cyclical in developed countries and counter-cyclical in developing countries. That said, private inflows are pro-cyclical and public in flows are counter-cyclical in both groups of countries. The dominance of private (public) in flows in developed (developing) countries drives the difference in total net inflows. We rationalize these patterns using a dynamic stochastic two-sector model of a small open economy facing borrowing constraints. Private agents over-borrow because of the pecuniary externality arising from constraints. The government saves ...

Trade Integration, Global Value Chains and Capital Accumulation
Motivated by increasing trade and fragmentation of production across countries since World War II, we build a dynamic two-country model featuring sequential, multistage production and capital accumulation. As trade costs decline over time, global-value-chain (GVC) trade expands across countries, particularly more in the faster growing country, consistent with the empirical pattern. The presence of GVC trade boosts capital accumulation and economic growth and magnifies dynamic gains from trade. At the same time, endogenous capital accumulation shapes comparative advantage across countries, ...

Saving Europe?: The Unpleasant Arithmetic of Fiscal Austerity in Integrated Economies
What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore cross-country spillovers of tax changes. Instead, we examine this issue using a two-country model that matches the observed elasticity of the capital tax base by introducing endogenous capacity utilization and a partial depreciation allowance. Tax hikes have adverse effects on macro aggregates and welfare, and trigger strong ...

Structural Change and Global Trade
Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. Using a Ricardian trade model incorporating endogenous structural change, we quantify how this substantial shift in consumption has affected trade. Without structural change, we find that the world trade to GDP ratio would be 15 percentage points higher by 2015, about half the boost delivered from declining trade costs. In addition, this structural change has lowered the global welfare gains from trade integration by almost 40 percent over the past four decades. Absent further ...

The dynamic relationship between global debt and output
Given the ramifications of indebtedness for global growth, researchers and policymakers are keenly interested in the mechanisms underlying the linkages between debt and economic output. In our research, summarized in this article, we find that a debt shock adversely affects future economic output, and the impact is most pronounced in developing countries and in countries with a fixed exchange rate regime. This information and related results from the study are useful for policymakers considering appropriate levels of debt as well as an exchange rate regime that is most conducive to economic ...

The Relationship between Debt and Output
In this paper we empirically explore the relationship between debt and output in a panel of 72 countries over the period 1970–2014 using a vector autoregression (VAR). We document two puzzling empirical findings that contrast with what is predicted by a standard small open economy model by Aguiar and Gopinath (2007), where debt and output endogenously respond to total factor productivity (TFP) shocks. First, developing countries’ debt falls after a positive output shock, while the model predicts a debt expansion. Second, output declines in developed and developing countries after a debt ...

The global welfare impact of China: trade integration and technological change
This paper evaluates the global welfare impact of China's trade integration and technological change in a quantitative Ric a rdian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a balanced one in which China's productivity grows at the sam e rate in each sector, and an unbalanced one in which China's comparative disadvantage sectors catch up disproportionately faster to the world productivity frontier. Contrary to a well-known conjecture (Samuelson 2004), the large majority of countries in the sample, including the developed ones, ...
