Marketing expenditure plays a crucial role in determining performance since promotion mix generates market shares and revenues for the brands. But, nowadays, the impact of promotional expenditure is appeared to be non-responsive to influence the revenue and profitability as the consumers are now having ample scopes of escaping advertisement. Moreover consumers prefer the products that are associated with some social cause. Hence the purpose of this paper is to compare the impact of societal and marketing expenditure on profitability. To attain the purpose, we have employed empirical results of various Indian banks by developing a model using profit after tax (PAT), societal and marketing expenses. In particular, we have considered log-linear model as it fits better for all the banks when compared with the linear model. Further, we have compared the profit elasticity between societal and marketing expenses. Finally, association between the profit performance status and the comparative profit contribution at equal expenditure has been tested by employing non-parametric χ² test and Cramer’s V. Result proves the efficiency of ‘expenditure in social concern’ compared to ‘Expenditure in traditional marketing tools’ and hence it suggests for adopting alternative route, that is, societal means of promotion for better customer connect.

This paper discusses and analyzes risk measure properties in order to understand how a risk measure has to be used to optimize the investor's portfolio choices. In particular, we distinguish between two admissible classes of risk measures proposed in the portfolio literature: safety-risk measures and dispersion measures. We study and describe how the risk could depend on other distributional parameters. Then, we examine and discuss the differences between statistical parametric models and linear fund separation ones. Finally, we propose an empirical comparison among three different portfolio choice models which depend on the mean, on a risk measure, and on a skewness parameter. Thus, we assess and value the impact on the investor's preferences of three different risk measures even considering some derivative assets among the possible choices.
