Payment Card Rewards Programs and Consumer Payment Choice (2008)

Ching, Andrew, Hayashi, Fumiko

We estimate the direct effects of rewards card programs on consumer payment choice for in-store transactions. By using a data set that contains information on consumer perceived attributes of payment...

Consumer Learning and Heterogeneity: Dynamics of Demand for Prescription Drugs after Patent Expiration (2008)

Ching, Andrew

This paper investigates whether aggregate consumer learning together with consumer heterogeneity in price sensitivity could explain why (i) there is a slow diffusion of generic drugs into the market,...

Identification of INSL5, a New Member of the Insulin Superfamily (2007)

Darrell Conklin Catherine, Betty A. Haldeman, Andrew Ching, Theodore E. Whitmore, Si Lok, ...

this paper, we increase the membership of the vertebrate insulin gene superfamily by the cloning of a new insulin or relaxin-like hormone. Insulin-like peptide 5 (INSL5; named ZINS3 in the patent...

The Effects of Detailing on Prescribing Decisions under Two-Sided Learning (2007)

Ching, Andrew, Ishihara, Masakazu

A fundamental question in pharmaceutical marketing management is: How does the effectiveness of detailing change when additional information on drugs is revealed via patients' experiences during the...

The Effects of Detailing on Prescribing Decisions under Quality Uncertainty (2007)

Ching, Andrew, Ishihara, Masakazu

We develop a structural model of detailing and prescribing decisions under an environment where detailing helps physicians obtain the current information sets about drug qualities. Our model assumes...

The Price Consideration Model of Brand Choice (2007)

Ching, Andrew, Erdem, Tulin, Keane, Michael

The workhorse brand choice models in marketing are the multinomial logit (MNL) and nested multinomial logit (NMNL). These models place strong restrictions on how brand share and purchase incidence...

Are All Managers Created Equal? (2007)

Avi Goldfarb, Botao Yang, Pat Bajari, Andrew Ching, Allan Collard-wexler, Shane Greenstein, ...

Some managers are better than others. Based on the cognitive hierarchy framework of Camerer, Ho, and Chong (2004), we develop a structural econometric model that estimates the level of strategic...

Understanding Firm, Physician and Consumer Choice Behavior in the Pharmaceutical Industry

Puneet Manchanda, Dick Wittink, Andrew Ching, Paris Cleanthous, Min Ding, Xiaojing Dong, ...

This paper argues that the pharmaceutical industry represents an exciting opportunity to carry out academic research. The nature of the industry allows researchers to answer new questions, develop...

Recent Advances in Structural Econometric Modeling: Dynamics, Product Positioning and Entry

Jean-Pierre Dubé, K. Sudhir, Andrew Ching, Gregory Crawford, Michaela Draganska, Jeremy Fox, ...

In the empirical analysis of consumer markets, recent literature has begun to explore the dynamics in both consumer decisions as well as in firms' marketing policies. Other research has begun to...

Cloning and characterization of human protease-activated receptor 4

Xu, Wen-feng, Andersen, Henrik, Whitmore, Theodore E., Presnell, Scott R., Yee, David P., Ching, Andrew, ...

Protease-activated receptors 1–3 (PAR1, PAR2, and PAR3) are members of a unique G protein-coupled receptor family. They are characterized by a tethered peptide ligand at the extracellular amino...

Payment card rewards programs and consumer payment choice

Andrew Ching, Fumiko Hayashi

Card payments have been growing very rapidly. To continue the growth, payment card networks keep adding new merchants and card issuers try to stimulate their existing customers’ card usage by...

Protease-activated receptors 1–3 (PAR1, PAR2, and PAR3) are members of a unique G protein-coupled receptor family. They are characterized by a tethered peptide ligand at the extracellular amino...

Bayesian Estimation of Dynamic Discrete Choice Models

Susumu Imai, Neelam Jain, Andrew Ching

We propose a new methodology for structural estimation of dynamic discrete choice models. We combine the Dynamic Programming (DP) solution algorithm with the Bayesian Markov Chain Monte Carlo...

Dynamic Equilibrium in the US Prescription Drug Market After Patent Expiration

Andrew Ching

In this paper I formulate and estimate an empirical dynamic oligopoly model that incorporates consumer learning, consumer heterogeneity and forward-looking firms. I apply this model to explain the...

A Dynamic Oligopoly Structural Model for the Prescription Drug Market After Patent Expiration

Andrew Ching

Motivated by the slow diffusion of generic drugs and the increase in prices of brand-name drugs after generic entry, I incorporate consumer learning and consumer heterogeneity into an empirical...

The Role of Campaign War Chest in Congressional Careers

Andrew Ching, Antonio Merlo

The main goal of this paper is to investigate the role of campaign fund in congressional careers. To achieve this goal, we specify a dynamic model of career decisions of a member of Congress. In...

A Practitioner's Guide to Bayesian Estimation of Discrete Choice Dynamic Programming Models

Andrew Ching, Susumu Imai, Masakazu Ishihara, Neelam Jain

This paper provides a step-by-step guide to estimating discrete choice dynamic programming (DDP) models using the Bayesian Dynamic Programming algorithm developed by Imai Jain and Ching (2008) (IJC)....
