Deep Integration and Production Networks: An Empirical Analysis

In this paper, the two way relationship between deep integration and production networks trade is investigated. Deep integration is captured by a set of indices constructed in terms of policy areas covered in preferential trade agreements. An augmented gravity equation is estimated to investigate the impact of deep integration on production networks. The results show that on average, signing deeper agreements increases production networks trade between member countries by almost 35 percentage points. In addition, the impact of deep integration is higher for trade in automobile parts and information and technology products compared with textiles products. To analyse whether higher levels of network trade increase the likelihood of signing deeper agreements the literature on the determinants of preferential trade agreements is followed. The estimation results show that, after taking into account other PTAs determinants, a ten per cent increase in the share of production network trade over total trade increases the depth of an agreement by approximately 6 percentage points. In addition, the probability of signing deeper agreements is higher for country pairs involved in North-South production sharing and for countries belonging to the Asia region.

Product Standards and Margins of Trade: Firm Level Evidence

This paper analyses the trade effects of restrictive product standards on the margins of trade for a large panel of French firms. To focus on restrictive product standards only, we use a new database compiling the list of measures that have been raised as concerns in dedicated committees of the WTO. We restrict our analysis to the subset of Sanitary and Phyto-Sanitary (SPS) regulatory measures and analyse the effects of product standards on three variables: (i) probability to export and to exit the export market (firm-product extensive margins), (ii) value exported (firm-product intensive margin) and (iii) export prices. In particular we study whether firms size, market shares and export orientation modify the effect of SPS measures. We find that SPS measures discourage exports. We also find a negative effect of SPS imposition on the intensive margins of trade. Finally, the negative effects of SPS measures on the extensive and intensive margins of trade are attenuated for big firms.

How Much Will the Belt and Road Initiative Reduce Trade Costs

This paper studies the impact of transport infrastructure projects of the Belt and Road Initiative on shipment times and trade costs. Based on a new data on completed and planned Belt and Road transport projects, Geographic Information System analysis is used to estimate shipment times before and after the Belt and Road Initiative. Two sets of data are computed to address different research questions: a global database based on an analysis of 1,000 cities in 191 countries and 47 sectors and a regional database that focuses on more granular information (1,818 cities) for Belt and Road economies only. The paper uses sectoral estimates of “value of time” to transform changes in shipment times into changes in ad valorem trade costs at the country-sector level. The findings show that the Belt and Road Initiative will significantly reduce shipment times and trade costs. For the world, the average reduction in shipment time will range between 1.2 and 2.5 percent, leading to reduction of aggregate trade costs between 1.1 and 2.2 percent. For Belt and Road economies, the change in shipment times and trade costs will range between 1.7 and 3.2 percent and 1.5 and 2.8 percent, respectively. Belt and Road economies located along the corridors where projects are built experience the largest gains. Shipment times along these corridors decline by up to 11.9 percent and trade costs by up to 10.2 percent. The paper also shows that these effects are magnified by policy reforms that reduce border delays and improve corridor management.
