October 2019Rules and Commitment in Communication: an Experimental Analysis
with Alessandro Lizzeri, Jacopo Perego: w26404
We study the role of commitment in communication and its interactions with rules, which determine whether or not information is verifiable. Our framework nests models of cheap talk, information disclosure, and Bayesian persuasion. Our model predicts that commitment has opposite effects on information transmission under the two alternative rules. We leverage these contrasting forces to experimentally establish that subjects react to commitment in line with the main qualitative implications of the theory. Quantitatively, not all subjects behave as predicted. We show that a form of commitment blindness leads some senders to overcommunicate when information is verifiable and undercommunicate when it is not. This generates an unpredicted gap in information transmission across the two rules, sug...
August 2018Frictions in a Competitive, Regulated Market: Evidence from Taxis
with Alessandro Lizzeri, Tobias Salz: w24921
This paper presents a dynamic general equilibrium model of a taxi market. The model is estimated using data from New York City yellow cabs. Two salient features by which most taxi markets deviate from the efficient market ideal are, first, matching frictions created by the need for both market sides to physically search for trading partners, and second, regulatory limitations to entry. To assess the importance of these features, we use the model to simulate the effect of changes in entry, alternative matching technologies, and different market density. We use the geographical features of the matching process to back out unobserved demand through a matching simulation. This function exhibits increasing returns to scale, which is important to understand the impact of changes in this market a...
