Per-capita Income, Tastes for Quality, and Exports Across Countries
报告人： 徐楠 博士
This paper studies how per-capita income affects trade patterns of quality-differentiated goods across countries. A product's perceived quality depends on intrinsic characteristics of the product as well as consumers' tastes for quality. In addition to aggregate income, this paper features a taste for quality channel through which a destination's income per capita causes the variety-quality tradeoff in product exports. I build a model combining non-homothetic preferences and product quality heterogeneity in which rich consumers demand disproportionately more high-quality varieties than poor consumers. To assess the evidence, I construct a quality index and examine cross-country variation in prices and export sales at the firm-product level with Chinese disaggregate trade data from the Household Audio and Video Equipment industry. In line with the model's predictions, the results show that firms charge higher prices in richer countries, and the effects of GDP per capita on export sales differ by product quality.
