This paper identifies the most restrictive limit that rules of origin can enforce and still continue to guarantee gains from trade for free trade area formation in general settings. Many commonly used rules of origin exceed this condition in practice. Second, free trade areas generally involve...

This paper shows how gains from trade are conditioned by love of variety, defined as the extent to which an additional product variety generates benefits in either final or intermediate consumption. We develop a multi-country, multi-sector gravity trade model where love of variety is...

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...

Modern trade models attribute the dispersion of international prices to physical and man-made barriers to trade, to the pricing-to-market by heterogeneous producers, and to differences in the quality of output offered by firms. This paper analyzes a quantitative general equilibrium model that...

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...

This paper takes a welfare-view on eastern enlargement of the EU, focusing on incumbent countries. Enlargement is decomposed into three elements: Single-market integration on commodity markets, budgetary costs from EU-expenditure policies, and singlemarket-induced migration from new to present...

This paper compares the solution methods and baseline calibration of three different quantitative trade models (QTMs): computable general equilibrium (CGE) models, structural gravity (SG) models and models employing exact hat algebra (EHA). The different solution methods generate identical...

Geoeconomic concepts are gaining importance in EU trade policy. In this context new trade policy instruments are designed to protect the internal market against unfair trade practices, coercive actions as well as to ensure sustainable supply chains and the protection of human rights. The study...
