September 2019State-Dependent Demand Estimation with Initial Conditions Correction
with Andrey Simonov, Jean-Pierre H. Dubé, Günter J. Hitsch: w26217
We analyze the initial conditions bias in the estimation of brand choice models with structural state dependence. Using a combination of Monte Carlo simulations and empirical case studies of shopping panels, we show that popular, simple solutions that mis-specify the initial conditions are likely to lead to bias even in relatively long panel datasets. The magnitude of the bias in the state dependence parameter can be as large as a factor of 2 to 2.5. We propose a solution to the initial conditions problem that samples the initial states as auxiliary variables in an MCMC procedure. The approach assumes that the joint distribution of prices and consumer choices, and hence the distribution of initial states, is in equilibrium. This assumption is plausible for the mature consumer packaged good...

March 2017The Value of Flexible Work: Evidence from Uber Drivers
with M. Keith Chen, Judith A. Chevalier, Emily Oehlsen: w23296
Participation in non-traditional work arrangements has increased dramatically over the last decade, including in settings where new technologies lower the transaction costs of providing labor flexibly. One prominent example of flexible work is the ride-sharing company Uber, which allows drivers to provide (or not provide) rides anytime they are willing to accept prevailing wages for providing this service. An Uber-style arrangement offers workers flexibility in both setting a customized work schedule and also adjusting the schedule from week to week, day to day, and hour to hour. Using data on hourly earnings for Uber drivers, we document the ways in which drivers utilize this real-time flexibility and we estimate the driver surplus generated by this flexibility. We estimate how drivers’ r...

August 2015Income and Wealth Effects on Private-Label Demand: Evidence From the Great Recession
with Jean-Pierre Dubé, Günter J. Hitsch: w21446
We measure the causal effects of income and wealth on the demand for private-label products. Prior research suggests that these effects are large and, in particular, that private-label demand rises during recessions. Our empirical analysis is based on a comprehensive household-level transactions database matched with price information from store-level scanner data and wealth data based on local house value indices. The Great Recession provides a key source of the variation in our data, with a large and geographically diverse impact on household incomes over time. We estimate income and wealth effects using “within” variation of income and wealth at the household level. Our estimates can be interpreted as income and wealth effects consistent with a consumer demand model based on utility max...

April 2009State Dependence and Alternative Explanations for Consumer Inertia
with Jean-Pierre Dubé, Günter J. Hitsch: w14912
For many consumer packaged goods products, researchers have documented a form of state dependence whereby consumers become "loyal" to products they have consumed in the past. That is, consumers behave as though there is a utility premium from continuing to purchase the same product as they have purchased in the past or, equivalently, there is a psychological cost to switching products. However, it has not been established that this form of state dependence can be identified in the presence of consumer heterogeneity of an unknown form. Most importantly, before this inertia can be given a structural interpretation and used in policy experiments such as counterfactual pricing exercises,alternative explanations which might give rise to similar consumer behavior must be ruled out. We develop a ...
