This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

We combine econometric estimation with quantitative modelling to generate projections on the trade, GDP, and emissions effects of a potential trade liberalization agreement in energy related environmental goods (EREGs) and environmentally preferable products (EPPs). Trade liberalization can...

Trade and investment can be effective means of implementation of the 2030 Sustainable Development Agenda. However, stand-alone trade and investment liberalization policies aimed at enhancing economic development may have negative side-effects on non-economic facets of sustainable development. As...

Firms play a critical role in the global economy. In this paper, we survey the behavior of firms in the international economy, both in theory and in the data. We first summarize the key empirical facts that motivate the study of firms in trade. Then, we detail recent theoretical developments on...

We study the equilibrium determinants of firm-level heterogeneity in a model in which firms can affect the variance of their productivity draws at the entry stage and explore the implications in closed and open economy. By allowing firms to choose the size of their investment in innovation...

This paper uses firm-level data for Mexican exporters to understand how firm-level export decisions shape a country's aggregate exports. The data allows for a characterization of both the crosssectional distribution of Mexican exports, across destinations and across exporting firms, and of the...

This chapter reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters,...
