An empirical comparison of consumer-based measures of brand equity

This article compares eleven different consumer-based brand equity measures and evaluates their convergence. Predictive validity at the individual and aggregate levels is also investigated. Measures based on the dollar metric method and discrete choice methodology predict choices extremely well in a simulated shopping environment, as well as purchase-intention and brand-quality scales.

Validation of stochastic models: Some perspectives

The focus of the paper is the process of model validation. The discussion illustrates some problems encountered in validating stochastic models, with special reference to market behavior models. A brief discussion of some important dimensions of model validation are presented. The discussion focuses on the role of simulation to generate sample universes for realistic output validation (both at micro and macro levels) of a stochastic model. Also, some light is shed upon two neglected aspects of model validation, experimentation to test the realism of a model's policy implications and a comparative evaluation with existing models. It is hoped for that the article has raised some important issues for the attention of a serious model builder.     

Measurement of deprivation and poverty based on the proportion spent on food: An exploratory exercise

This paper attempts to broaden the scope of poverty measurement. First, a brief review of measurements based on monetary and nutritional norms is presented. Then, it is suggested that data on the proportion spent on food (PSF) by per capita expenditure can be exploited to measure the incidence of deprivation and the incidence of poverty. It is postulated that until the food needs are satisfied, people spend relatively more of their incremental income on food and this behaviour reveals itself as increasing or invariant PSF as income (or expenditure) increases up to a critical level. The proportion of people up to that critical level are deprived of the required food and the proportion constitutes the incidence of deprivation. The average expenditure at the deprivation point (the PSF level from where its decline is clear-cut and smooth) can be used to develop an arbitrary poverty line. Data for rural India are used to illustrate the measurement of deprivation and poverty.     

Efficient Investment in Children

Many would say that children are society's most precious resource. So, how should we invest in them? To gain insight into this question, a dynamic general equilibrium model is developed where children differ by ability. Parents invest time and money in their offspring, depending on their altruism. This allows their children to grow up as more productive adults. First, the efficient allocation is characterized. Next, this is compared with the outcome that arises when financial markets are incomplete. The situation where child-care markets are also lacking is then examined. Additionally, the consequences of impure altruism are analyzed. Journal of Economic Literature Classification Numbers: D1, D31, D58, I2.

Extended Framework for Modeling Choice Behavior

We review the case against the standard model of rational behavior and discuss the consequences of various anomalies of preference elicitation. A general theoretical framework that attempts to disentangle the various psychological elements in the decision-making process is presented. We then present a rigorous and general methodology to model the theoretical framework, explicitly incorporating psychological factors and their influences on choices. This theme has long been deemed necessary by behavioral researchers, but is often ignored in demand models. The methodology requires the estimation of an integrated multi-equation model consisting of a discrete choice model and the latent variable model system. We conclude with a research agenda to bring the theoretical framework into fruition.     

A simulation based methodology for modeling a university Research Support Service System

The paper presents a methodology for modeling a university Research Support Service System (RSSS). RSSS effectiveness is measured in terms of net research time available to researchers, response time of support services, and the cost to provide services. The model consists essentially of delineating each function of the RSSS as a network and simulating flow of researcher generated inputs through the network in order to collect statistics necessary to compute performance measures. The analysis concerns system performance changes in response to procedural modifications in the institution, removal of external procedural constraints imposed on the system, and changes in organizational configuration. The model can prove to be a valuable asset to the present-day RSSS managements in examining their Research Support Service Systems or developing similar models.
