  • Sold to China: Container traffic in the Port of Piraeus Article dans une revue

    This article analyzes the effects of the acquisition of the Port of Piraeus by the Chinese shipping operator COSCO in July 2016 on the organization of container traffic in Europe. Using real-time container ship positions provided by vessel tracking systems between 2015 and 2019, we study the impact of the privatization of the Greek port on its attractiveness and on that of competing ports for the ships of the various operators, and more particularly of COSCO. Difference-in-difference estimates suggest that the number of container ship calls to the Port of Piraeus has increased following its privatization, but that this increase in attractiveness corresponds mainly to vessels operated by COSCO with a capacity of more than 3000 twenty-foot equivalent units, and in particular to the largest of them. We do not identify any crowding out effect between operators in Piraeus: the use of Piraeus by the vessels of other operators remains relatively unchanged. The privatization of Piraeus seems to have imposed the Greek port as COSCO’s transhipment hub for the European market without this being to the detriment of ports in any other particular European area.

  • Is There a Bright Side to the China Syndrome? Rising Export Opportunities and Life Satisfaction in China Article dans une revue

    Export growth affects individuals through numerous and contradictory channels. In China, the development of exports has promoted economic development and income growth, but it has also disrupted social structures and work environments. This paper explores the overall effect of exports on perceived well-being by combining responses from a large longitudinal survey covering over 45,000 Chinese with a shift-share measure of local export opportunities. Results show that individuals’ perceived life satisfaction increases significantly in prefectures that benefited from greater export opportunities, despite a negative effect on self-reported health. The positive well-being gains go beyond a simple income effect. These non-monetary gains are related to the individuals’ professional life: export-related well-being gains are stronger for working-age individuals (especially men and low-skilled workers), are largest for workers in the manufacturing sector (which produces the vast majority of China’s exports), and are found when the satisfaction indicator focuses on work but not on other aspects of daily life.

  • The effects of the Rana Plaza collapse on the sourcing choices of French importers Article dans une revue

    This paper analyzes the effects of a major reputational shock affecting textile importers from Bangladesh. The collapse of the Rana Plaza building in April 2013 generated a surge of activism and media coverage specifically targeting the firms that sourced from the factories affected by the disaster. Using monthly firm-level import data from French Customs, we study any potential disruption in these firms’ imports from all origins, and specifically from Bangladesh. We use a difference-in-differences approach. French textile imports from Bangladesh rose continuously after the shock, and the overall imports of retailers sourcing from the Rana Plaza show no drop after the event. Our results do reveal a relative decline in Bangladeshi imports for those retailers named for sourcing from the collapsed factories. This effect is mirrored by a relative increase in these exposed firms’ imports from four particular countries, which are non-Asian and are geographically closer to France.

  • Estimating the Repercussions from China’s Export VAT Rebate Policy Article dans une revue

    Our study shows that China’s export value-added tax (VAT) rebate system is a major industrial policy that affects its exports. We use export data at the HS6 product level for a panel of 329 Chinese cities over the 2003-2012 period to assess how changes in the export VAT tax have affected China’s export performance. We consider different trade margins in terms of volumes, prices, and the number of countries served. To counter endogeneity, we exploit variations in the expected impact of the export VAT rebates by trade regime, which come from an eligibility rule disqualifying certain export flows from the rebates. Our results suggest that a 1 percent decline in the export VAT tax leads to a 7.2 percent relative increase in eligible export values at the city level. This effect is due to an adjustment of quantities and the number of foreign markets served while the average unit values of exports remain unchanged.

  • Local financial development and constraints on domestic private-firm exports: Evidence from city commercial banks in China Article dans une revue

    We show that the development of city commercial banks (CCBs) across China has alleviated the constraints from China’s domestic financial-market inefficiency on the export activity of domestic private firms. Considering the export behavior of 260 cities between 1997 and 2012, we confirm the well-established under-performance of domestic private firms in financially more vulnerable sectors compared to foreign affiliates in China. We show that a greater number of CCB branches raises domestic private-firm exports disproportionately more in financially-dependent sectors, which is in line with improved financing conditions for these companies. This improvement in export performance appears to result from both an increase in the number of destination countries and a decline in prices. CCB development is moreover associated with a reduction in the systematic disadvantage of domestic private firms relative to foreign-owned firms in export markets resulting from their greater financial exclusion. We, however, also find that private-firm export performance has deteriorated relative to that of state-owned firms, casting doubt on the ability of CCBs to end the systematic bias of lending in favor of the state sector.

  • Social responsibility scandals and trade Article dans une revue

    This paper studies the effect of social responsibility scandals on the imports of consumer products, by focusing on an event which generated massive consumer mobilization against neglecting firms, namely the collapse of the Rana Plaza building affecting the textile industry in Bangladesh. We investigate the import repercussions of this major shock in the perceived quality of clothing producers sourcing in Bangladesh. In line with the well-documented home bias in trade and home-country media slant, we assume that consumers’ reaction will be stronger when domestic firms are named and shamed. Our empirical strategy uses a difference-in-difference approach that compares imports from Bangladesh of countries according to whether some of their companies were directly associated with the collapse of the Rana Plaza. Our results are consistent with demand being sensitive to social responsibility scandals. While aggregate imports from Bangladesh continue to increase during the whole period (2010–2016), there is a marked disruption that affects countries whose brands were named and shamed by activists and the media after the disaster. In addition, the decline in imports is all the greater as the number of NGO campaigns on the misbehavior of national textile retailers is high.
