How social and economic conditions impact socioeconomic mobility. The case of Spain
We rely on Permanent Income to define a socioeconomic stratification system based on a latent trait measurement model using objective and widely available socioeconomic variables as reflective indicators, with an official panel of households spanning 2006-2020 in Spain. We obtain an objective and transparent stratification of Spanish society for these 15 years, and track social mobility at the household level between consecutive years that includ…
Financial Insecurity and Deprivation Life Satisfaction, Self Determination, and Consumption Adequacy at the Bottom of the Pyramid How Economic Contractions and Expansions Affect Expenditure Patterns L…
Consumers worldwide are struggling with serious economic challenges. In virtually every nation, the disparity is growing between the wealthy and the poor. Consumer researchers are responding by trying to understand how consumers experience and cope with financial insecurity and deprivation. They are using an array of psychological, economic, and sociological theories coupled with methodological approaches ranging from experiments to econometrics …
How Economic Contractions and Expansions Affect Expenditure Patterns
In this study, we attempt to understand how household budget allocations across various expenditure categories change when the economy is in recession or expansion. The common assumption is that a household's tastes would not change as a function of economic conditions and therefore any adjustments in expenditure patterns during economic contractions/expansions would simply be due to changes in the consumption budget. Standard economic models tra…
Multi-Index Binary Response Analysis of Large Data Sets
We propose a multi-index binary response model for analyzing large databases (i.e., with many regressors). We combine many regressors into factors (or indexes) and then estimate the link function via parametric or nonparametric methods. Neither the estimation of factors nor the determination of the number of factors requires ex ante knowledge of the link between the response and regressors. Furthermore, applying perturbation theory, we furnish a …
American Time-Styles: A Finite-Mixture Allocation Model for Time-Use Analysis
Time-use has already been the subject of numerous studies across multiple disciplines such as economics, marketing, sociology, transportation and urban planning. However, most of this research has focused on comparing demographic groups on a few broadly defined activities (e.g., work for pay, leisure, housework, etc.). In this study we take a holistic perspective, identifying a typology of latent "time-styles," that defines the different ways peo…
Accounting for Voter Heterogeneity within and across Districts with a Factor-Analytic Voter-Choice Model
In this study, we propose a model of individual voter behavior that can be applied to aggregate data at the district (or precinct) levels while accounting for differences in political preferences across districts and across voters within each district. Our model produces a mapping of the competing candidates and electoral districts on a latent “issues” space that describes how political preferences in each district deviate from the average voter …
An Empirical Bayes Procedure for Improving Individual-Level Estimates and Predictions From Finite Mixtures of Multinomial Logit Models
Unobserved heterogeneity in random utility choice models can be dealt with by specifying either a multinomial or a normal distribution of the coefficients, leading to finite mixture logit and mixed logit models. Focusing on the former, we show that individual-level estimates and predictions of finite mixtures estimated by maximizing the likelihood function can be improved through integration over the estimation error of the hyperparameters, using…
Satisfaction, Repurchase Intent, and Repurchase Behavior: Investigating the Moderating Effect of Customer Characteristics
Despite the claim that satisfaction ratings are linked to repurchase behavior, few attempts can be found that relate satisfaction ratings to actual repurchase behavior. This article fills this void by presenting a conceptual model for relating satisfaction ratings and repurchase behavior. The model is based on the premise that ratings observed in a typical customer satisfaction survey are error-prone measures of the customer's true satisfaction, …
Exploratory Tobit Factor Analysis for Multivariate Censored Data
We propose Multivariate Tobit models with a factor structure on the covariance matrix. Such models are particularly useful in the exploratory analysis of multivariate censored data and the identification of latent variables from behavioral data. The factor structure provides a parsimonious representation of the censored data and reduces the dimensionality of the integration required in evaluating the likelihood. In addition, the factor model para…
Unobserved Heterogeneity as an Alternative Explanation for "Reversal" Effects in Behavioral Research
Behavioral researchers use analysis of variance (ANOVA) tests of differences between treatment means or chi-square tests of differences between proportions to provide support for empirical hypotheses about consumer behavior. These tests are typically conducted on data from “between-subjects” experiments in which participants were randomly assigned to conditions. We show that, despite using internally valid experimental designs such as this, aggre…
Value Segmentation: A Model for the Measurement of Values and Value Systems
This article develops a model for the measurement of human values that, rather than obtain aggregate measurements, identifies distinct value systems within a population and classifies individuals according to them. These value systems are inferred from the stated priority rankings, obtained from each individual via the Rokeach value survey
Measuring Market Efficiency and Welfare Loss
This study presents a general methodology capable of addressing a number of fundamental questions in consumer policy. Are consumers paying more than the minimum price for a given bundle of attributes? If so, what brands cost more than the consumer needs to pay? What would be the degree of improvement in the consumer's well being if some intervention sets the price of such inefficient brands at the efficient level? We apply the methodology to data…
