August 2017On the Relationship Between Quality and Productivity: Evidence from China's Accession to the WTO
with Haichao Fan, Stephen R. Yeaple: w23690
This paper presents an analysis of the effect of China's entry into the WTO on the quality choices of Chinese exporters in terms of their outputs and their inputs. Using highly disaggregated firm-level data, we show that the quality upgrading made possible by China's tariff reductions was concentrated in the least productive Chinese exporters. These firms, which had been laggards in terms of quality prior to the tariff reduction, were the most aggressive in increasing the quality of their exports and their inputs and in redirecting their exports toward high income markets where demand for high quality goods is strong. Our empirical results are consistent with a simple model featuring scale effect and non-Hicks' neutral productivity that disproportionately affects the efficiency with which ...
December 2016Growth Policy, Agglomeration, and (the Lack of) Competition
with Wyatt J. Brooks, Joseph P. Kaboski: w22947
Industrial clusters are promoted by policy and generally viewed as good for growth and development, but both clusters and policies may also enable non-competitive behavior. This paper studies the presence of non-competitive pricing in geographic industrial clusters. We develop, validate, and apply a novel test for collusive behavior. We derive the test from the solution to a partial cartel of perfectly colluding firms in an industry. Outside of a cartel, a firm's markup depends on its market share, but in the cartel, markups across firms converge and depend instead on the total market share of the cartel. Empirically, we validate the test using plants with common owners, and then test for collusion using data from Chinese manufacturing firms (1999-2009). We find strong evidence for non-com...
July 2014Trade Liberalization, Quality, and Export Prices
with Haichao Fan, Stephen R. Yeaple: w20323
This paper presents theory and evidence from highly disaggregated Chinese data that tariff reductions induce a country's producers to upgrade the quality of the goods that they export. The paper first documents two stylized facts regarding the effect of trade liberalization on export prices and its relation with product differentiation. Next, the paper develops a simple analytic framework that relates a firm's choice of quality to its access to imported intermediates. The model predicts that a reduction in the import tariff induces an incumbent importer/exporter to increase the quality of its exports and to raise its export price in industries where the scope for quality differentiation is large while to lower its export price in industries where the scope for quality differentiation is sm...

March 2008The Higher Educational Transformation of China and Its Global Implications
with John Whalley, Shunming Zhang, Xiliang Zhao: w13849
This paper documents the major transformation of higher education that has been underway in China since 1999 and evaluates its potential global impacts. Reflecting China's commitment to continued high growth through quality upgrading and the production of ideas and intellectual property as set out in both the 10th (2001-2005) and 11th (2006-2010) five-year plans, this transformation focuses on major new resource commitments to tertiary education and also embodies significant changes in organizational form. This focus on tertiary education differentiates the Chinese case from other countries who earlier at similar stages of development instead stressed primary and secondary education. The number of undergraduate and graduate students in China has been grown at approximately 30% per year sin...
