We consider an international cartel whose members interact repeatedly in their own as well as in third-country segmented markets. Cartel discipline-an inverse measure of the degree of competition between firms-is endogenously determined by the cartel’s incentive compatibility constraint (ICC),...

This paper explores the quantitative consequences of transatlantic trade liberalization envisioned in a Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union. Our key innovation is to develop a new quantitative spatial trade model and to use an...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

Trade liberalization can imply slow and long adjustment processes. Taking account of these adjustment processes can change the evaluation of trade policy, especially when policy makers care more about the next couple of years than the infinite future. In this paper I analyze the setting of...

Amid a general rise in protectionism and a trade war between the world's two largest economies, this paper analyzes changes in gains from trade for the world over a decade marked by rapid global economic integration preceding the global financial crisis of 2007-08. It employs state-of-the-art...

In March 2018, representatives of member countries of the African Union signed the African Continental Free Trade Area (AfCFTA) agreement. This agreement provides a framework for trade liberalization in goods and services and is expected to eventually cover all African countries. Using a...

The outcome of a trade war (with import tariffs and export subsidies) between two countries is analysed in a Cournot duopoly and in a Bertrand duopoly with differentiated products. The model allows for asymmetries between the countries in terms of competitiveness. When the two countries are...

Welfare with the maximum-revenue tariff is compared to free-trade welfare under perfect competition in the case of a large country able to affect its terms of trade; under Cournot duopoly with differentiated products; and under Bertrand duopoly with differentiated products. Under perfect...
