Payment card rewards programs and consumer payment choice
Andrew T. Ching,Fumiko Hayashi +1 more
TL;DR: In this article, the effects of payment card rewards programs on consumer payment choice, by using consumer survey data, are analyzed. And the results suggest that consumers with credit card rewards use credit cards much more exclusively than those without credit-card rewards, even among those who carry a credit card balance.

Consumer Learning and Heterogeneity: Dynamics of Demand for Prescription Drugs after Patent Expiration
TL;DR: This paper investigated whether aggregate consumer learning together with consumer heterogeneity in price sensitivity could explain why there is a slow diffusion of generic drugs into the market, and brand-name originators keep increasing their prices over time even after the number of generic entrants has become fixed.

Payment Card Rewards Programs and Consumer Payment Choice
Andrew T. Ching,Fumiko Hayashi +1 more
TL;DR: In this paper, the effects of payment card rewards on consumer choice of payment methods were investigated and they found that removing rewards would increase their share of paper-based payment methods (i.e., cash and checks) measured in terms of in-store transactions by no more than 4 percentage points.

Bayesian Estimation of Dynamic Discrete Choice Models
TL;DR: In this paper, the authors combine the dynamic programming (DP) solution algorithm with the Bayesian Markov chain Monte Carlo algorithm into a single algorithm that solves the DP problem and estimates the parameters simultaneously.

Consumer learning and heterogeneity: Dynamics of demand for prescription drugs after patent expiration
TL;DR: In this paper, an empirical demand model with aggregate learning and consumer heterogeneity in price sensitivity is proposed to estimate the demand model jointly with a pseudo-pricing policy function, which is a reduced-form function of observed and unobserved state variables.
