A unilateral trade reform generates two opposite effects: market access expansion and strengthening of competitive pressures in the liberalized market. Using detailed trade and firm-level data from France, we investigate how French firms' product scope and export sales changed after Chinese liberalization vis-à-vis Asian liberalization. Our findings suggest that lower Chinese import tariffs account on average for 7 percent of the new products exported by French firms, and for 18 percent of additional French export sales. These results are robust when accounting for foreign competition faced by French firms in the liberalized market.

This paper studies tariff-tax reforms in a calibrated two-region global New Keynesian model composed of a developing and an advanced region. In our baseline calibration, a revenue-neutral reform that lowers tariffs in developing countries can reduce domestic welfare. The reason is that the increase in developing countries welfare due to higher output is dominated by the welfare losses stemming from the deterioration of the terms of trade. On the other hand, the reform increases output and welfare in the advanced countries and in the world as a whole. The effects that we highlight have not been studied in previous contributions to the literature, which typically looks at tariff-tax reforms using a small open economy framework. Nominal rigidities have important implications for adjustment dynamics in our model. In the case of a \"point-for-point\" reform, for example, price stickiness implies that the international dynamics of output is reversed compared to a revenue neutral reform.

With the start of the process of its transition to a market economy in early 1990, Romania joined the ranks of other reforming Eastern European countries. At the starting point of its reform program, however, Romania was in a deep economic and institutional crisis and had no experience in even modest attempts to reform its economy. This paper outlines the main characteristics of the Romanian economic system before the reform, and presents the evolution of the reform program, as well as its achievements in the first year or so since it was launched.

Existing political economy models explain the politics of trade policy using inter-industry differences. However, this article finds that much of the variation in U.S. applied tariff rates in fact arises within industry. I offer a theory of trade liberalization that explains how product differentiation in economic markets leads to firm-level lobbying in political markets. High levels of product differentiation eliminates the collective action problem faced by exporting firms while import-competing firms need not fear product substitution. To test this argument, I construct a new dataset on lobbying by all publicly traded manufacturing firms from reports filed under the Lobbying Disclosure Act of 1995. I find that productive exporting firms are more likely to lobby to reduce tariffs, especially when their products are sufficiently differentiated. I also find that highly differentiated products have lower tariff rates. The results challenge the common focus on industry-level lobbying for protection.

This paper studies the impact of a regional free trade agreement, MERCOSUR, on technology upgrading by Argentinean firms. To guide empirical work, I introduce technology choice in a model of trade with heterogeneous firms. The joint treatment of the technology and exporting choices shows that the increase in revenues produced by trade integration can induce exporters to upgrade technology. An empirical test of the model reveals that firms in industries facing higher reductions in Brazil's tariffs increase investment in technology faster. The effect of tariffs is highest in the upper-middle range of the firm-size distribution, as predicted by the model.

A quantitative model brings together theories linking international trade to quality, technology, and demand for skills. Standard effects of trade on importers and exporters are magnified through domestic input linkages. We estimate the model with data from Colombian manufacturing firms before the 1991 trade liberalization. A counterfactual trade liberalization is broadly consistent with post-liberalization data. It increases skill intensity from 12 to 16 percent, while decreasing sales. Imported inputs, estimated to be of higher quality, and domestic input linkages are quantitatively important. Economies of scale, export expansion, and reallocation of production are small and cannot explain post-liberalization data.
