This paper questions whether the overseas expansion of a country’s retailers fosters overall bilateral exports towards these host markets. To address this question, we consider an empirical trade model, where the foreign sales of multinational retailers reduce the fixed and variable trade...

Empirical evidence shows that R&D spending is highly correlated with firm productivity, highly concentrated among large firms, and responsive to trade liberalization. This paper develops a model of product upgrading with heterogeneous firms that captures these characteristics by allowing firms...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

Standard theoretical models would predict that a currency depreciation generates an increase in net exports. However, recent emerging market crises, accompanied by sharp exchange rate devaluations, have often been followed by a fall in or a stagnation of exports. This paper provides a simple...

This paper considers the locational choice of firms in an upstream and a downstream industry. Both industries are imperfectly competitive, with firms subject to increasing returns. There are transport costs between the two locations. Depending on the level of these costs there may be a single...

A standard gravity model was applied to estimate the magnitude of potential trade flows between Pakistan and the nine ECO member countries. The major issue in this analysis is to explore that Intra- ECO trade has great potential for Pakistan and that it got lower share than its potential. The...

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...
