Stand-alone marketing models are well-suited to deal with different behavioral features such as variation in transaction frequency (customer heterogeneity with latent classes), recency and attrition (“buy ‘till you die” models), and more general changes in customer transaction rates...

This paper develops a two-stage statistical analysis to identify and assess the effect of a sample bias associated with an individual's household role. Survey responses to questions about the respondent's role in household finances and a sampling design in which some households have all members...

This preliminary note investigates perception bias: To what extent do individual opinions confound reality? We estimate the relative gap between self-declared estimates and real data. We asked a sample of Philippine respondents about the incidence of diabetes and smartphone usage in their...

The typical analysis on the effectiveness of soda taxes relies on price elasticity estimates from static demand models, which ignores consumers inventory behaviors and their persistent tastes. This article provides estimates of the relevant price elasticities based on a dynamic demand model that...

A methodology is proposed to estimate structural models of product line competition. This methodology enables researchers to estimate demand systems accounting for the endogeneity of the mix of products available in each market, an issue which is typically ignored in the empirical literature. In...

Modeling consumer choice in different areas has lead to an increase use of discrete choice models. Probit or Multinomial Logit Models are often the base of further empirical research of consumer choice. In some of these models the equations to solve have no closed-form expression. They include...
