Working Paper
Price equalization does not imply free trade
In this paper we show that price equalization alone is not sufficient to establish that there are no barriers to international trade. There are many barrier combinations that deliver price equalization, but each combination implies a different volume of trade. Therefore, in order to make statements about trade barriers it is necessary to know the trade flows. We demonstrate this first theoretically in a simple two-country model. We then extend the result quantitatively to a multicountry model with two sectors. We show that for the case of capital goods trade, barriers have to be large in ...
Working Paper
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 ...

Capital goods trade and economic development
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 ...

Journal Article
Price Equalization Does Not Imply Free Trade
In this article, the authors demonstrate the possibility of price equalization in a two-country world with barriers to international trade. For price equalization to occur when the countries are asymmetric, the country with higher productivity must also be the one with the lower trade barrier. A corollary of the authors? result is that small departures from purchasing power parity do not necessarily imply that world trade is mostly integrated.
Working Paper
Capital goods trade, relative prices, and economic development
International trade in capital goods has quantitatively important effects on economic development through two channels: capital formation and aggregate TFP. We embed a multi country, multi sector Ricardian model of trade into a neoclassical growth framework. Our model matches several trade and development facts within a unified framework: the world distribution of capital goods production and trade, cross-country differences in investment rate and price of final goods, and cross-country equalization of price of capital goods. Reducing barriers to trade capital goods allows poor countries to ...

Capital Goods Trade, Relative Prices, and Economic Development
International trade in capital goods has quantitatively important effects on economic development through capital formation and TFP. Capital goods trade enables poor countries to access more efficient technologies, leading to lower relative prices of capital goods and higher capital-output ratios. Moreover, poor countries can use their comparative advantage and allocate their resources more efficiently, and increase their TFP. We quantify these channels using a multisector, multicountry, Ricardian model of trade with capital accumulation. The model matches several trade and development facts ...
