We compare the effect of geographic distance on eBay and total international trade flows. We consider the same 61 countries and basket of goods for both types of transactions. We find the effect of distance to be on average 65% smaller on eBay. We argue this difference is due to a reduction in search costs; it increases with product differentiation and is higher when trade partners speak different languages, when corruption in the exporting country is high and when uncertainty avoidance is high in the importing country. Moreover, eBay's seller-rating technology further reduces the distance effect on eBay.2 Comtrade data are collected from national customs offices and include total trade flows, which may include eBay and other online trade flows. We, therefore, use the term 'Total' to describe Comtrade trade data. While the share of online trade in total trade during our study period is unknown, we can assume that it is below 8%, the share of e-commerce in US retail sales in 2012 according to Forrester-Research (2013). 3 Hortac ßsu et al. (2009) do provide international evidence using MercadoLibre, another online market, though it only covers 12 Latin American countries.Additional Supporting Information may be found in the online version of this article: Data S1.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.

During the final years of the Multifiber Agreement the US imposed strict import quotas on Chinese apparel while it gave African apparel duty-and quota-free access. The combination of these policies led to a rapid but ephemeral rise of African exports. In this paper we argue that the African success can be explained by a temporary transhipment of Chinese apparel driven by quota-hopping Chinese assembly firms. We first provide a large body of anecdotal evidence on the Chinese apparel wave in African countries. Second, we show that Chinese apparel exports to African countries predict US imports from the same countries and in the same apparel categories but only where transhipment incentives are present, i.e. for products with binding quotas in the US and for countries with preferential access to the US unconstrained by rules of origin. Using input-output linkages, we then show that African countries imported quasi-finished products with little assembly work left to do, rather than primary textile inputs. We estimate that direct transhipment may account for around half of AGOA countries apparel exports.

Migrant Networks and Trade:The Vietnamese Boat People as a Natural Experiment *We provide evidence for the causal pro-trade effect of migrants and in doing so establish an important link between migrant networks and long-run economic development. To this end, we exploit a unique event in human history, i.e. the exodus of the Vietnamese Boat People to the US. This episode represents an ideal natural experiment as the large immigration shock, the first wave of which comprised refugees exogenously allocated across the US, occurred over a twenty-year period during which time the US imposed a complete trade embargo on Vietnam. Following the lifting of trade restrictions in 1994, US exports to Vietnam grew most in US States with larger Vietnamese populations, themselves the result of larger refugee inflows 20 years earlier.
