Product quality and intra-industry trade

In this study, we argue that the conventional intra-industry trade (IIT) index does not address the quality issue directly and propose a methodology to make full use of unit-price gap information to deduce quality differences between simultaneously exported and imported products. By applying this measure to German trade data at the eight-digit level, we study the quality improvement of Chinese export goods in its IIT with Germany. We compare the case of China with those of Eastern European countries, which are also major trading partners of Germany. Our results show that the unit-value difference in IIT between Germany and Eastern European countries is clearly narrowing. However, China's export prices to Germany are much lower than Germany's export prices to China, and this gap has not narrowed over the last 23 years. This is at odds with the common perception that China's product quality has improved, as documented by Rodrik (2006) and Schott (2008). Our results support Xu (2010), which argued that incorporating the quality aspect of the exported goods weakens or even eliminates the evidence of the sophistication of Chinese export goods in Rodrik (2006).

Does trade liberalization boost quality upgrading? : evidence from Indonesian plant-product-level data

In this study, we examine the effects of tariff reduction on firms' quality upgrading by employing an Indonesian plant-product-level panel dataset matched with a plant-level dataset. We explore the effects of lower output and input tariffs separately, by focusing on the apparel industry. By estimating the Berry-type demand function, we derive product-quality indicators based on the Khandelwal (Review of Economic Studies, 2010) methodology, which enables us to isolate quality upgrading from changes in prices. Our findings are as follows. First, a reduction in output tariffs does not affect product quality upgrading. Second, a reduction in input tariffs boosts quality upgrading in general. In particular, this impact is greater for import firms, which is consistent with the fact that the source of the boost is the import of high-quality foreign inputs.
