The authors study brand loyalties for durable goods using automobile survey data that are peculiarly censored and track only elapsed times since transitions but not the transition times themselves. This censoring problem is typical of commercially available durable goods survey data. However, little attention has been paid to such "last-move" data in the statistics or marketing literature on th…
The authors propose an econometric model of both the geographic locations of gasoline retailers in Singapore and price competition among retailers conditional on their geographic locations. Although market demand for gasoline is not observed, the authors are able to infer the effects of such demand from stations' locations and pricing decisions using available data on local market-level demogra…
The authors propose an empirical procedure to investigate the pricing behavior of manufacturers and retailers in the presence of state-dependent demand. Rather than assuming that firms are perfectly forward looking and therefore solving accordingly for dynamic equilibriums that would arise in the presence of state dependence, the authors systematically evaluate whether boundedly rational firms …
In usual practice, researchers specify and estimate brand-choice models from purchase data, ignoring observations in which category incidence does not occur (i.e., no-purchase observations). This practice can be problematic if there are unobservable factors that affect the no-purchase and the brand-choice decisions. The authors propose a model that is suitable for scanner-panel data in which th…
