Finance and inequality: a study of Indian states

Although a large literature exists on finance and economic growth, few studies have empirically examined the relationship between finance and inequality. Using grouped national household sample survey data on monthly household consumption expenditure at the sub-national level for the years 1999–2000 to 2006–2007, we examine the relationship between Financial Development (FD) and rural and urban inequality in India. The results indicate that FD is associated with a reduction in inequality, but only in the urban areas. Further, inequality is found to be higher in the richer states compared to less developed and low income states, and as state income increases, inequality also increases both in the rural and urban areas. Finally, our results show that increase in population per bank branch leads to higher inequality in urban areas but decline in rural areas.     

Type IV error in marketing research: The investigation of ANOVA interactions

Considerable attention is typically given to Type I and Type II errors when conducting empirical research. This article presents an error, often ignored in marketing and consumer behavior research, termed Type IV error. This error results from the improper investigation of interactions in an analysis of variance. A review of research published inJournal of Marketing Research andJournal of Consumer Research found widespread occurrence of Type IV errors. Illustrative improper interpretations of interactions are discussed and approaches for properly investigating interactions are presented. Situations where interactions need to be tested and interpreted are noted. These situations are contrasted with those where it is more appropriate to examine cell mean differences. The correct use of graphs of cell means is also discussed. Guidelines are presented for avoiding Type IV errors.

Timestyles: Role factor influences on the convergence and divergence of couples' complementary and substitute activity patterns

Using a role theory framework, this research focuses on convergence and divergence in complementary and substitute activities for husbands and wives. Hypotheses on the effects of children and wife's employment were assessed for a national sample of married men reporting on their and their wives' activities for a typical weekday and Saturday. Role factors are shown to have a significant impact on timestyles and the specific activities emerging as substitutes and complements.     

On the significance of statistically insignificant results in consumer behavior experiments

Experimentation is the sine qua non of consumer behavior research, and much of what is thought to be known about the behavior of consumers is based on findings from experiments. However, many articles that report consumer behavior experiments contain one or more results that are significantly insignificant. That is, one or more experimental results are so unusually weak or minuscule that they are unlikely to have come about by chance. As such, significantly insignificant results can be due to the “failure” of the theory underlying an experiment and/or the flawed design or implementation of an experiment. Consequently, significantly insignificant results have implications for the theories and methodologies employed in consumer behavior experiments, the quality of conclusions drawn from the experiments, and the credibility of the consumer behavior research discipline as a whole.
