Abstract

This dissertation consists of three chapters that represent a contribution to the research on the role of product quality in international trade. The first chapter presents an empirical analysis of the relationship between the volatility of bilateral trade flows and the quality of products exported. We argue that, under the hypothesis of non-homothetic preferences, the variability of income generates larger fluctuations of the demand of high-quality imported products. Our findings indicate that a possible drawback of exporting high-quality products is represented by the higher exposure to income variability of destination countries. The second chapter sets up an empirical analysis on cross-country panel data to estimate the effect of the quality up-grade of exported products on the change of the wage premium measured at  industry level. Our findings show that industries which up-grade the quality of exports, increase the average level of wages paid, implying a change in the workforce composition towards categories of better paid jobs. In the third chapter, we examine whether consumer's valuation for quality of French imported products is stronger in countries where consumers' tastes are similar to the French ones. To identify taste proximity, we rely on information collected from the online travel company TripAdvisor. The findings of our empirical analysis suggest that consumer’s valuation for product quality depends on the origin of imports and is stronger for products imported from countries with similar tastes to that of French consumers.
