Abstract:
There is often a lack of reliable quality provision in many markets in developing countries and firms generally lack a reputation for quality. One potential explanation is that mistrust due to past bad behavior can make reputation-building difficult. I examine this hypothesis in a setting that features typical market conditions in developing countries: the retail watermelon markets in a major Chinese city. I first demonstrate empirically that there is substantial asymmetric information between sellers and buyers on quality and a stark absence of quality premium at baseline. I then randomly introduce one of two branding technologies into 40 out of 60 markets–one sticker label that is widely used and counterfeited and one novel expensive laser-cut label. The experiment findings show that laser-branding induced sellers to provide higher quality and led to higher sales profits. However, after the intervention was withdrawn, all markets reverted back to baseline. I incorporate the experimental variation into an empirical model of consumer learning and seller reputation building. The results suggest that consumers are hesitant to upgrade their perception under stickers, which makes reputation-building a low-return investment. While the new technology enhances learning, the resulting increase in profits is not sufficient to cover the fixed cost of the technology for small individual sellers. Counterfactual analysis shows that information friction and fragmented market lead to significant under-provision of quality.

Abstract:
Are quid pro quo (technology for market access) policies effective in facilitating knowledge spillover to developing countries? We study this question in the context of the Chinese automobile industry where foreign firms are required to set up joint ventures with domestic firms in return for market access. Using a unique dataset of detailed quality measures along multiple dimensions of vehicle performance, we document empirical patterns consistent with knowledge spillovers through both ownership affiliation and geographical proximity: joint ventures and Chinese domestic firms with ownership or location linkage tend to specialize in similar quality dimensions. The identification primarily relies on within-product variation across quality dimensions and the results are robust to a variety of specifications. The pattern is not driven by endogenous joint-venture network formation, overlapping customer base, or learning by doing considerations. Leveraging additional micro datasets on part suppliers and worker flow, we document that supplier network and labor mobility are important channels in mediating knowledge spillovers. However, these channels are not tied to ownership affiliations. Finally, we calibrate a simple learning model and conduct policy counterfactuals to examine the role of quid pro quo. Our findings show that ownership affiliation facilitates learning but quality improvement is primarily driven by the other mechanisms.
