Dynamic relationships among R&D,advertising, inventory and firm performance

Firms’ spending on R&D, advertising, and inventory holding affect firm performance, which in turn affects future spending in each of these three areas. Effective allocation of resources across R&D, advertising, and inventory holding is challenging since an understanding of their dynamic inter-relationships is necessary. Past research has not examined these spending issues simultaneously. We estimate inter-relationships among the effects of firms’ R&D spending, advertising spending, and inventory holding on sales and firm value (as measured by its Tobin’s Q) using a vector auto regression model of a panel of publicly listed U.S. high technology manufacturing firms. Insights from the computation of long-term effects indicate that advertising spending and inventory holding increase sales, while R&D spending does not, and advertising and R&D spending increase firm value, while inventory holding does not. In addition, firm spending in all three functions is positively affected by sales but negatively by firm value. We discuss the implications of the study for marketing literature and managerial practice.     

A comparative analysis of differential consumer response across supermarket and specialty store in the candy category

Retailing industry has undergone tremendous change in its complexity and sophistication over the past few years. Globally we are witnessing the evolution of retailing industry from traditionally micro-managed small retail formats like mom and pop store to modern corporate-managed large retail formats like supermarkets. Consumers are also shopping across these various store formats even for the products in similar categories. In this research, we posit that consumer purchases in the similar categories may very well be characterized by differential responses to marketing mix across different store formats. The proposed model accounts for the influences that these diverse response parameters and preferences have on one another as well as consumer heterogeneity. Our results show that sensitivities to marketing mix as well as correlations in preferences do indeed vary across formats for consumer purchases in similar categories.     

Action control,proxy control,and consumers' evaluations of the service exchange

This article adopts a consumer's point of view, and extends current literature that models the relationships between consumers' control perceptions, service providers' fair behaviors, and consumers' satisfaction with the exchange. Perceived control is disassembled into action and proxy control and their differential actions in the service exchange discussed. This article models, for the first time, the joint effects of perceived control and service provider behaviors on consumer satisfaction by explicitly connecting service‐provider fair behaviors to consumers' perceptions of control. The results from two repeated‐measures experiments provide support for the hypotheses. Specifically, a multivariate analysis of the data demonstrated main effects for the experimental manipulations on perceived control, perceived fairness, satisfaction, and behavioral intentions. An interaction effect between perceived control and perceived fairness was also evident in one experiment. Future research and managerial implications are discussed. © 2004 Wiley Periodicals, Inc.     

Household Food Insecurity and Maternal and Child Nutritional Status: Evidence from Maharashtra

In this paper we rigorously examine the association of household food security status with maternal and child nutritional status exploring a rich micro‐level database, the Comprehensive Nutrition Survey Maharashtra 2012. Using Household Food Insecurity Access Scale (HFIAS) as a metric to measure household food security, we apply simultaneous probit models to estimate the effect of food insecurity on maternal and child nutritional outcomes. The modelling framework addresses possible endogeneity in the above relationship. Findings indicate that household food insecurity increases the risk of maternal and child underweight with no effect on child stunting, wasting or maternal overweight. Women’s decision‐making power mediates these associations. Food security interventions should be effective in tackling the concerns with undernutrition, however, food alone is not the solution. A mix of nutrition‐specific and nutrition‐sensitive policies is warranted. Food security interventions should be integrated into policies for human development.
