Trade Liberalization, Input Intermediaries and Firm Productivity: Evidence from China

We investigate theoretically and empirically the role of wholesalers in mediating the productivity effects of trade liberalization. Intermediaries provide indirect access to foreign produced inputs. The productivity effects of input tariff cuts on firms that do not directly import therefore depends on the extent that wholesalers are a feature of input supply within an industry. Using firm level data from China, we document that wholesalers play no such role for direct importers. However, other firms experience productivity gains from reducing input tariffs if trade intermediation of foreign inputs within their sector is high. They suffer efficiency losses otherwise

Productivity, relationship-specific inputs and the sourcing modes of multinationals

We investigate the roles of productivity and the specificity of inputs for the international sourcing strategy of firms which are part of a multinational network. We present a framework in which firms decide to import from a foreign independent supplier or from their related party abroad according to these two dimensions. We use a detailed survey that provides a detailed geographical breakdown of French firms' imports at the product level as well as the sourcing mode used for each transaction. The dataset also provides information to estimate the firms' productivity and their intensity in relationship-specific inputs. After controlling for countries of origin, products and sectors specific effects, the empirical results provide evidence that for the most productive multinationals the likelihood of trading through an independent supplier is higher especially if they use relationship-specific inputs intensively

The political economyof trade policy: Gone for good? Subsidies with export share requirements in China: 2002-13

This paper presents a simple model of subsidies with export share requirements (ESR) in a heterogeneous firm environment. A two-country general equilibrium version of the model with a single 100% ESR is calibrated using firm-level data from the 2002 wave of the Business Environment and Enterprise Performance Survey collected by the World Bank for China. The calibrated model is used to gauge the change in subsidies with ESR that is consistent with the fall in the share of 'pure exporters', firms exporting all their output, observed in China, from 25.7% in 2002 to 11.1% in 2013. Our results indicate that a 6.9% reduction in the ad-valorem subsidy rate available to firms that export all their output is consistent with the observed fall in their share of exporting firms. Expenditure in subsidies (as a share of value-added) falls by 66% and welfare in China increases by 1.76% while real income in the rest of the world falls by 0.59%

Subsidies with Export Share Requirements in China

A subsidy is subject to an export share requirement (ESR) when firms must export more than a certain share of their output to receive it. Such incentives are frequently found in free trade zones, export processing regimes and measures targeted at foreign investors, both in China and other developing countries. In this paper we provide the first quantitative assessment of the effect that using subsidies with ESR has on exports, the intensity of competition and welfare, both in the enacting country and its trading partners, using a two-country model of trade with heterogeneous firms. We find that the subsidy with ESR boosts exports more than an equivalent unconditional subsidy available to all exporters. Crucially, the subsidy with ESR provides greater protection to low-profitability firms, while the unconditional subsidy does the opposite. The combination of export promotion and lower intensity of domestic competition generated by the subsidy with ESR can be described as “protectionism through exporting.” The imposition of an ESR, however, greatly exacerbates the welfare loss associated with subsidizing exporters

Twin Peaks

Received wisdom suggests that most exporters sell the majority of their output domestically. In this paper, however, we show that the distribution of export intensity not only varies substantially across countries, but in a large number of cases is also bimodal, displaying what we refer to as twin peaks. We reconcile this new stylized fact with an otherwise standard, two-country model of trade in which firms are heterogeneous in terms of the demand they face in each market. We show that when firm-destination-specific revenue shifters are distributed lognormal, gamma, or Frechet with sufficiently high dispersion, the distribution of export intensity has two modes in the boundaries of the support and their height is determined by a country's size relative to the rest of the world. We estimate the deep parameters characterizing the distribution of export intensity. Our results show that when the conditions for the existence of twin peaks are met, differences in relative market size can explain most of the observed variation in the distribution of export intensity across the world

Does the Elimination of Export Requirements in Special Economic Zones A ect Export Performance? Evidence from the Dominican Republic

Special economic zones, one of the most important instruments of industrial policy in developing countries, often feature export share requirements. That is, firms located in these zones are obliged to export more than a certain stated share of their output to enjoy the wide array of incentives available there, a practice prohibited by the World Trade Organization. This paper exploits the staggered removal of export requirements across products and over time in the special economic zones of the Dominican Republic to evaluate whether the importance of exports originating from the zones was affected by the elimination of export requirements. The findings show that entry increased among firms in special economic zones, while the average value of export transactions fell for existing exporters following the reforms. At the same time, continuous exporters were unaffected by the policy change, possibly because these firms were not constrained by the export requirement. Overall, special economic zones became more important with respect to the number of exporters based there but not in terms of the value of exports. The findings suggest that the elimination of performance requirements made it more attractive for firms to be based in special economic zones

Supplier Search and Re-matching in Global Sourcing - Theory and Evidence from China

In this paper, we consider a dynamic search-and-matching problem of a firm with its intermediate input supplier. In our model, a headquarter currently matched with a supplier, has an interest to find and collaborate with a more efficient partner. However, supplier switching through search and re-matching is costly. Given this trade-off between the fixed costs and the expected gains from continued search, the process will stop whenever the headquarter has found a sufficiently efficient supplier. Using firm-product-level data of fresh Chinese exporters to the United States, we obtain empirical evidence in line with the predictions of our theory. In particular, we find that the share of short-term collaborations is higher in industries with more supplier-cost dispersion, an indication of higher expected search opportunities

Spatial exporters

In this paper, we provide causal evidence that firms serve new markets which are geographically close to their prior export destinations with a higher probability than standard gravity models predict. We quantify the impact of this spatial pattern using a data set of Chinese firms which had never exported to the EU, the United States, and Canada before 2005. These countries imposed import quotas on textile and apparel products until 2005 and experienced a subsequent increase in imports of previously constrained Chinese firms. Controlling for firm-destination specific effects and accounting for potential true state dependence we show that the probability to export to a country increases by about two percentage points for each prior export destination which shares a common border with this country. We find little evidence for other forms of proximity to previous export destinations like common colonizer, language or income group

Evaluating the Impact of Export Finance Support On Firm-level Export Performance: Evidence from Pakistan

This paper evaluates the impact of two export finance support schemes: The Export Finance Scheme (EFS) and the Long-Term Finance Facility for Plant & Machinery (LTFF) on firm-level export performance. These policies offer loans to exporters at concessionary interest rates to finance short-term working capital and long-term investment in machinery and equipment respectively. To do so, we combine customs data with information about which firms participate in each scheme and the value of the loans they obtain between 2015 and 2017. We find that EFS and LTFF increased the growth rate of exports sales by 7 and 8-11 percentage points respectively. Neither policy exerts a significant impact on the number of products that a firm exports or the number of foreign countries it sells to. Our analysis indicates that facilitating long-term investment in physical capital is more cost effective to raise exports than subsidizing exporters' working capital needs

Special Economic Zones, Global Value Chains, and the Degree of Economic Linkages in the Dominican Republic

The Dominican Republic is often considered an example of the successful implementation of Special Economic Zones (henceforth SEZs) in the Western hemisphere. The zones fueled economic growth during the 1980s and 1990s and, while they experienced a sharp decline in employment due in part to the expiry of the end of the Multi-Fiber Agreement and stronger international competition in the textile and apparel industry in 2005, signs of recovery have been observed since 2009. Surgical equipment, chemicals and plastics, and footwear have recently emerged as the new drivers of export dynamism in the zones (World Bank, 2015). The objective of this report is to inform the policy discussion around the developmental impact of SEZs in the Dominican Republic by empirically assessing i) the implications of regulatory reforms aimed at complying with WTO disciplines regarding the elimination of incentives conditioned on export performance for SEZs firms, ii) the extent to which SEZs participate in Global Value Chains, and iii) their linkages with domestic suppliers. The report is organized as follows: The second section presents the historical importance of SEZ as an engine of economic growth in the country. The third section depicts the structural shift in terms of production in SEZs and evaluates the degree of value addition taking place in the Dominican Republic. The fourth section evaluates the degree and evolution of linkages between SEZs and local firms. The fifth section shows the impact of the regulatory changes in the SEZ regimen undertaken to comply with WTO disciplines. Finally, some conclusions and policy recommendations are presented in section six
