We develop and experimentally test a discrete choice model of an expert who recommends one of multiple actions to a decision maker who might take no action. Consistent with the recent theoretical literature on cheap talk recommendations, we find that recommendations are "persuasive" in that they...

In this paper, we use a unique micro-level data set from Istanbul to investigate the empirical relationship between inflation and price dispersion. In particular, our data set includes price observations from three distinct store types: bakkals (convenience stores), pazars (bazaars), and...

We develop an economic model of “greenwash,” in which a firm strategically discloses environmental information and a non-governmental organization (NGO) may audit and penalize the firm for failing to fully disclose its environmental impacts. We identify conditions under which NGO punishment...

Web search technologies are fundamental tools to easily navigate through the huge amount of information available in the Internet. One particular type of search technologies are the so- called shopbots, or comparison sites. The emergence of Internet shopbots and their implications for price...

This paper considers identification and estimation of a general model for online price competition. We show that when the number of competing firms is unknown, the underlying parameters of the model can still be identified and estimated employing recently developed results on measurement error....

The Babylonian bridal auction, described by Herodotus, is regarded as one of the earliest uses of an auction in history. Yet, to our knowledge, the literature lacks a formal equilibrium analysis of this auction. We provide such an analysis for the two-player case with complete and incomplete...

When are comparative statements credible? For instance, when can a professor rank different students for an employer, or a stock analyst rank different stocks for a client? We show that simple complementarity conditions ensure that an expert with private information about multiple issues can...

In this paper, we apply supermodular game theory to the equilibrium search literature with sequential search. We identify necessary and sufficient conditions for strategic complementarities and prove existence of search market equilibrium. When firms are identical, the Diamond Paradox obtains...
