Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using...

This paper examines the interdependence between innovation and imports of intermediates, and their joint impact on productivity. We do so by developing a quantitative model with heterogeneous firms and international trade where firms can invest in R&D and source inputs internationally....

The literature on the benefits and costs of financial globalization for developing countries has exploded in recent years, but along many disparate channels with a variety of apparently conflicting results. We attempt to provide a unified conceptual framework for organizing this vast and growing...

Tax evasion, by its very nature, is difficult to observe. In this Paper, we present a case study of tax evasion in China. The novel feature of our approach is that at a very disaggregated level of individual products, we can measure evasion relatively precisely, by comparing the values that...

This paper furnishes robust evidence that the WTO has had a powerful and positive impact on trade, amounting to about 120% of additional world trade (or US$8 trillion in 2003 alone). The impact has, however, been uneven. This, in many ways, is consistent with theoretical models of the GATT/WTO....

When trade costs are of the iceberg type (Samuelson 1952) and markups are independent of trade costs, relative prices across markets are distorted, but relative prices within markets are not. When trade costs depart from the analytically convenient iceberg type, distortion will also occur within...

In this Paper, we provide a case study of the impact of globalization on income inequality using data across Chinese regions. The literature on cross-country studies has been criticized because differences in legal systems and other institutions across countries are difficult to control for, and...

The recent media and political attention on service outsourcing from developed to developing countries gives the impression that outsourcing is exploding. As a result, workers in industrial countries are anxious about job losses. This Paper aims to establish what are the hypes and what are the...

In this paper we ask why the gravity model of international trade also work well for foreign direct investment (FDI) flows or multinational production (MP). We propose a model of trade and horizontal FDI, where the subsidiary is allowed to source inputs from the headquarters. Under certain...

This paper proposes a framework for gross exports accounting that breaks up a country’s gross exports into various value-added components by source and additional double counted terms. By identifying which parts of the official trade data are double counted and the sources of the double...
