Many contemporary theoretic studies of trade over geography reduce to an ex- amination of constant-elasticity reactions to changes in iceberg trade costs. These impacts are readily analyzed in simple constant-returns models based on the Arm- ington (1969) assumption of regionally differentiated...

Following Smith's advocacy of free trade and competition, David Ricardo attempts to strengthen his theory of absolute advantage, which excludes from international trade countries which have no advantages over others, by eliminating this weakness. To do so, Ricardo introduces to the economics...

I develop a stylized model of multi-stage production in which the time length of each stage is endogenously determined. Letting the production process mature for a longer period of time increases labor productivity, but it comes at the cost of higher working capital needs for firms. Under...

On the occasion of the 25th anniversary of the WTO, this paper re-estimates the impact of WTO accession on growth. Joining the multilateral trading system not only expands access to international markets but also requires commitment to domestic reforms. Tang and Wei (2009) showed that there is...

Recent statistical advances suggest new ways of looking at growth accounting when global value chains (GVCs) are taken into consideration. The relative contribution of consumption, investment and net exports to economic growth are resized according to their net domestic value-added, discounting...

Trade liberalization is no Pareto-improvement - there are winners (high-skilled) and losers (low-skilled). To compensate the losers the government is assumed to introduce unemployment benefits (UB). These benefits are financed by either a wage tax, a payroll tax, or a profit tax. Using a...

In this paper we directly test the proposed productivity hierarchy of direct, indirect and non-exporters using firm-level data from 105 developing and transition countries. Using both regression analysis and propensity score matching, we find strong evidence to suggest that direct exporters are...

Proper measurement and aggregation of trade costs is of paramount importance for sound academic and policy analysis of the determinants - particularly those of policy - of economic outcomes. The international trade profession has witnessed significant new developments, both on the theoretical...

This study replicates Ahn, Khandelwal, and Wei’s (2011) model of intermediary trade. The study produces two main results. First, the authors are able to reproduce empirical evidence for AKW’s three main predictions for Chinese exports. This is impressive because much of the data for their...

In this paper, we show that there exists a special breed of firms that are active in both ordinary and processing exports. Contrary to the existing literature that describes processing firms as inferior, these mixed firms are superior to other firms in multiple dimensions, and hence we call them...
