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 that a representative opinion leader is responsible for updating the prior belief about the...

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 methods and consumer perceived acceptance of payment methods by merchants, we control for...

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 product lifecycle? To address this question, we develop a model of detailing and prescribing...

Internal market structure analysis infers both brand attributes and consumer preferences for those attributes from preference or choice data. The authors exploit a new method for estimating probit models from panel data to infer market structures that can be displayed in few dimensions, even...

Until recently, computational constraints forced researchers in the discrete choice area to limit themselves to very simple statistical models, such as the multinomial logit (MNL), in which choice probabilities could be evaluated quickly on a computer. But the MNL only makes sense as a...

In recent years, major advances have taken place in three areas of random utility modeling: (1) semiparametric estimation, (2) computational methods for multinomial probit models, and (3) computational methods for Bayesian stimation. This paper summarizes these developments and discusses their...

This paper describes how state-of-the-art methods of choice modeling can be used to analyze consumer choice behavior in "competitive" health insurance markets. I use the insurance choices of senior citizens in the U.S. as an example. I then consider the issue of whether consumers benefit when we...

The paper empirically analyzes stock market integration and the benefit possibilities of international portfolio diversification across the Southeast Asia (ASEAN) and U.S. equity markets. It employs daily sample of 6 ASEAN equity market indices and S&P 500 index as a proxy of U.S. market index...

In the present document it is exposed in an abstract way the models of credit portfolioes CreditMetricsTM, KMV, CreditRisk+, Credit Portfolio View in such a way that they could be calibrated and implemented in financial institutions where the quality and quantity of credit information is scanty,...
