Pakistan is facing a persistent trade deficit, resulting in foreign debts—leading to compromise on national policies and sovereignty. This study analyzes international trade of Pakistan with a special focus on exports. The analysis is conducted by various lenses including goods traded, trading...

A striking pattern in transaction-level data is the concentration of international shipments in the hands of a few large firms. One common feature of dominating high-performance firms is that they produce multiple products and ship them to many destinations. Motivated by the emergence of highly...

Correct estimates of import demand elasticities are essential for measuring the gains from trade and predicting the impact of trade policies. We show that estimates of import demand elasticities hinge critically on whether they are derived using trade quantities or trade values, and this...

This paper uses all Value Added Tax (VAT) changes across all EU Member States from 1988 to 2016 to estimate the effect of VATs on trade flows. We find small elasticities of trade flows with respect to VATs, in spite of some of the VAT changes being substantial. We estimate substantially smaller...

This paper assesses the quantitative importance of including sectoral heterogeneity in computing the gains from trade. Our framework draws from Caliendo and Parro (2015) and Alvarez and Lucas (2007) and has sectoral heterogeneity along five dimensions, including the elasticity of trade to trade...

David Ricardo indicated in his famous numerical example in the Principles that it would be advantageous to Portugal to import English cloth made by 100 men, although it could have been produced locally with the labor of only 90 Portuguese men. As the production of the cloth required less...

We introduce quality differentiation into a Ricardian model of international trade. We show that (1) quality differentiation allows industrialized countries to be active across the full board of products, complex and simple ones, while developing countries systematically specialize in simple...

We study the consequences of market uncertainty on international trade. An increase in foreign market uncertainty dampens China's aggregate exports on both the extensive and intensive margins. The adverse effects are more pronounced in industries facing tighter financial constraints than in...

This paper revisits the relationship between international trade and economic growth. We measure trade openness indices separately with respect to intermediate inputs and final goods and find that it is the former which turns out to be significant in explaining growth gains from trade. Using...

Both the Heckscher-Ohlin theorem and the factor price equalization theorem depend on or related to trade equilibriums. The trade equilibrium is the price equilibrium of production, consumption and trade. This study provides a price solution for the Heckscher-Ohlin model by using HOV assumption...
