Credit Constraints, Quality, and Export Prices: Theory and Evidence from China

This paper examines the relationship between the credit constraints faced by a firm and the unit value prices of its exports. The paper modifies Arkolakis’s (2010) model of trade with heterogeneous firms by introducing endogenous quality and credit constraints. The model predicts that tighter credit constraints faced by a firm reduce its optimal prices as its choice of lower-quality products dominates the price distortion effect resulting from credit constraints. However, a competing theory based on the alternative assumption that quality is exogenous across firms would predict completely opposite results: Prices increase as firms face tighter credit constraints. An empirical analysis using Chinese bank loans data, Chinese firm-level data from the National Bureau of Statistics of China (NBSC), and Chinese customs data strongly supports the predictions of the endogenous-quality model. Moreover, the predictions of the exogenous-quality model are supported by using quality-adjusted prices in regression analysis. In addition, we confirm the mechanism of quality adjustment: firms optimally choose to produce lower-quality products when facing tighter credit constraints.

Input-Trade Liberalization and Markups

This paper presents theory and evidence from Chinese firm-product data that, given firm productivity, trade liberalization increases product markups. This finding calls for a reconsideration of the well-established imports-as-market-discipline hypothesis. This paper further verifies underlying mechanisms behind this finding: input tariff reductions decrease marginal costs, and tariff effects on markup adjustments are more profound among firms of higher import dependence. By comparing results for two trade regimes -- ordinary trade wherein firms pay import tariffs to import, and processing trade wherein firms are not subject to import tariffs -- this paper finds that the aforementioned effects only apply to ordinary trade.
