TFP, Capital Deepening, and Gains from Trade

Using a dynamic, multicountry model with capital accumulation, we compute the exact transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization and calculate the resulting welfare gains from trade. We find that while the dynamic gains are different across countries, consumption transition paths look similar except for scale. In addition, dynamic gains accrue gradually and are about 60 percent of steady-state gains for everycountry. Finally, the contribution of capital accumulation to dynamic gains is four times that of total factor productivity.

Trade and Inequality in an Overlapping Generations Model with Capital Accumulation

We study the lifecycle aspect of within-country inequality that stems from capital and labor services supplied by individuals. Our environment is a combination of a multicountry trade model and an overlapping generations model with production and capital accumulation. Trade liberalization increases the measured total factor productivity in each country, which increases the marginal product of capital and incentivizes capital accumulation. Higher capital stock and higher measured productivity raise the marginal product of labor and, hence, wages. Inequality, measured by the ratio of old ...

Trade Liberalization versus Protectionism: Dynamic Welfare Asymmetries

We investigate whether the losses from an increase in trade costs (protectionism) are equal to the gains from a symmetric decrease in trade costs (liberalization). We incorporate dynamics through capital accumulation into a multicountry trade model and show that the welfare changes are asymmetric: Losses from protectionism are smaller than the gains from liberalization. In contrast, standard static trade models imply that the losses equal the gains. The intuition for asymmetry in our model is that, following protectionism, the economy can coast on its previously accumulated capital stock, so ...

On Terms of Trade, Offshoring Ties, and the Enforcement of Trade Agreements

This paper unpacks the role of offshoring in the enforcement of trade agreements. In a two-country model of task offshoring, we show that by depressing demand and thus demand for embodied labor, own-tariff effects on factor content weighted terms of trade are: (i) negative in upstream countries, backfiring on upstream workers, and (ii) positive in downstream countries which render imported labor tasks even cheaper. This progression in own-tariff effects on terms of trade along the supply chain presents a novel challenge to the effectiveness of dispute settlement rules designed to nullify ...

Offshoring in Developing Countries: Labor Market Outcomes, Welfare, and Policy

Does a reduction in offshoring cost benefit workers in the world's factories in developing countries? Using a parsimonious two-country model of offshoring we find very nuanced results. These include cases where wages monotonically improve, worsen, as well as where wages exhibit an inverted U-shaped relationship with the offshoring cost. We identify qualitative conditions under which these relationships hold. Since global welfare always rises with an improvement in offshoring technology, we find that there is a role for a wage tax or a minimum wage in the developing country. We derive the ...

Structural Change in Sub-Saharan Africa: An Open Economy Perspective

We study the evolution of manufacturing value added shares in 11 sub-Saharan African (SSA) countries through the lens of an open economy model of structural change. Our analysis leverages recent developments in input-output tables in SSA countries. Our model allows for income effects via non-homothetic preferences, substitution and relative price effects, as well as comparative advantage and specialization effects. We calibrate our model to include each SSA country with nine other major economies for each year between 2000 and 2018. We also do a similar set of calibrations for 11 developing ...

Capital goods trade and economic development

Almost 80 percent of capital goods production in the world is concentrated in 10 countries. Poor countries import most of their capital goods. We argue that international trade in capital goods has quantitatively important effects on economic development through two channels: (i) capital formation and (ii) aggregate TFP. We embed a multi country, multi sector Ricardian model of trade into a neoclassical growth model. Barriers to trade result in a misallocation of factors both within and across countries. We calibrate the model to bilateral trade flows, prices, and income per worker. Our model ...

The Impact of Regional and Sectoral Productivity Changes on the U.S. Economy

We study the impact of regional and sectoral productivity changes on the U.S. economy. To that end, we consider an environment that captures the effects of interregional and intersectoral trade in propagating disaggregated productivity changes at the level of a sector in a given U.S. state to the rest of the economy. The quantitative model we develop features pairwise interregional trade across all 50 U.S. states, 26 traded and non-traded industries, labor as a mobile factor, and structures and land as an immobile factor. We allow for sectoral linkages in the form of an intermediate input ...

The effects of terrorism on trade: a factor supply approach

The conventional view of terrorism is that it raises risks and, as a result, reduces trade. The authors use a factor supply approach to show that this hypothesis is not necessarily correct. They use a two-good, two-factor, small open economy model to show that terrorism can either reduce or raise trade depending on critical factors, such as the impact of terrorism on the intensive factor of the export or the import sector. They then extend the analysis to models with several goods and factors and identify conditions under which trade may rise or fall with a greater incidence of terrorism. ...

We argue that international trade in capital goods has quantitatively important effects on economic development through two channels: (i) capital formation and (ii) aggregate TFP. We embed a multi country, multi sector Ricardian model of trade into a neoclassical growth model. Barriers to trade result in a misallocation of factors both within and across countries. Our model matches several trade and development facts within a unified framework. It is consistent with the world distribution of capital goods production, cross-country differences in investment rate and price of final goods, and ...
