Consumers increasingly value the environmental and social responsibility of the production processes used by firms, yet these processes often remain unobservable, even after consumption. In this paper, we develop a simple model to examine firms’ technology choices and subsequent price...

Advertising on e-commerce marketplaces, wherein sponsored product listings are interleaved with organic product listings, is a large and growing phenomenon. In this paper, we both theoretically and empirically study whether including sponsored listings improves or hurts the overall quality and...

This paper studies sequential Bayesian persuasion games with multiple senders. We provide a tractable characterization of equilibrium outcomes. We apply the model to study how the structure of consultations affects information revelation. Adding a sender who moves first cannot reduce...

We study trust building in credence goods markets in a dynamic setting. An extreme lemon problem arises in the one-shot game and results in no trade. In the repeated game, an expert's honesty is monitored through consumers' rejection of his recommendations. We characterize the optimal...

Many everyday activities are habitual. Among the most common human activities is communication. If people primarily communicate in a common-interests environment, they may form habits of truth-telling and believing messages. If they primarily communicate in a conflicting-interests environment,...

In many markets buyers are poorly informed about which firms sell the product (product availability) and prices, and therefore have to spend time to obtain this information. In contrast, sellers typically have a better idea about which rivals offer the product. Information asymmetry between...

In this paper we analyse a model of oligopolistic competition in which consumers search without priors. Consumers do not have prior beliefs about the distribution of prices charged by firms and thus try to use a robust search procedure: they minimise the loss relative to the searcher, who knows...

This paper studies the general information disclosure model (Grossman, 1981; Milgrom, 1981) relaxing the assumption of monotonicity in preferences. I apply the belief-based approach, which is developed in Bayesian persuasion (Kamenica and Gentzkow, 2011) and applied to cheap talk (Lipnowski and...

Prices usually adjust much faster when costs increase than when costs decrease. The mechanism driving this Rockets-and-Feathers phenomenon is not well understood despite of ample empirical evidence for its existence.We use simple experimental markets with and without consumer search and either...

We implement a simple two-shop search model in the laboratory with the aim of testing if consumers behave differently in equivalent situations, where prices are displayed either as net prices or as gross prices with discounts. We compare search behavior in base treatments (where both shops post...
