|May 2020||The Value of Time: Evidence From Auctioned Cab Rides|
with Nicholas Buchholz, Laura Doval, Jakub Kastl, Tobias Salz: w27087
We estimate valuations of time using detailed consumer choice data from a large European ride hail platform, where drivers bid on trips and consumers choose between a set of potential rides with different prices and waiting times. We estimate consumer demand as a function of prices and waiting times. While demand is responsive to both, price elasticities are on average four times higher than waiting-time elasticities. We show how these estimates can be mapped into values of time that vary by place, person, and time of day. Regarding variation within a day, the value of time during non-work hours is 16% lower than during work hours. Regarding the spatial dimension, our value of time measures are highly correlated both with real estate prices and urban GPS travel flows. A variance decomposit...
|March 2015||Social Learning and Selective Attention|
with Andrew Caplin, John Leahy: w21001
Popularity is self reinforcing. The attention garnered by popular options propels further interest in them. Yet rather than blindly follow the crowd, most pay attention to how well these items match their tastes. We model this role of social learning in guiding selective attention and market dynamics. We confirm that attention focuses on options that quickly achieve popularity. Information externalities render the chosen set smaller than socially optimal. This rationalizes antitrust policies that encourage early experimentation. When attention costs are based on Shannon entropy, optimal policies are computable. With rich data, optimal choices can be identified for all consumer types.
