The marketing profession is being challenged to assess and communicate the value created by its actions on shareholder value. These demands create a need to translate marketing resource allocations and their performance consequences into financial and firm value effects. The objective of this paper is to integrate the existing knowledge on the impact of marketing on firm value. The authors first frame the important research questions on marketing and firm value and review the important investor response metrics and relevant analytical models, as they relate to marketing. The authors next summarize the empirical findings to date on how marketing creates shareholder value, including the impact of brand equity, customer equity, customer satisfaction, R&D, product quality and specific marketing-mix actions. In addition the authors review emerging findings on biases in investor response to marketing actions. The paper concludes by formulating an agenda for future research challenges in this emerging area.

Do price promotions generate additional revenue and for whom? Which brand, category, and market conditions influence promotional benefits and their allocation across manufacturers and retailers? To answer these questions, we conduct a large-scale econometric investigation of the effects of price promotions on manufacturer revenues, retailer revenues, and total profits (margins). A first major finding is that a price promotion typically does not have permanent monetary effects for either party. Second, price promotions have a predominantly positive impact on manufacturer revenues, but their effects on retailer revenues are mixed. Moreover, retailer category margins are typically reduced by price promotions. Even when accounting for cross-category and store-traffic effects, we still find evidence that price promotions are typically not beneficial to the retailer. Third, our results indicate that manufacturer revenue elasticities are higher for promotions of small-share brands, for frequently promoted brands and for national brands in impulse product categories with a low degree of brand proliferation and low private-label shares. Retailer revenue elasticities are higher for brands with frequent and shallow promotions, for impulse products, and in categories with a low degree of brand proliferation. Finally, retailer margin elasticities are higher for promotions of small-share brands and for brands with infrequent and shallow promotions. We discuss the managerial implications of our results for both manufacturers and retailers.long-term profitability, sales promotions, category management, manufacturers versus retailers, empirical generalizations, vector autoregressive models

Year after year, managers strive to improve financial performance and firm value through marketing actions such as new product introductions and promotional incentives. This study investigates the short-and long-term impact of such marketing actions on financial metrics, including top-line, bottom-line, and stock market performance. The authors apply multivariate time-series models to the automobile industry, in which both new product introductions and promotional incentives are considered important performance drivers. Notably, whereas both marketing actions increase top-line firm performance, their long-term effects strongly differ for the bottom line. First, new product introductions increase long-term financial performance and firm value, but promotions do not. Second, investor reaction to new product introduction grows over time, indicating that useful information unfolds in the first two months after product launch. Third, product entry in a new market yields the highest top-line, bottom-line, and stock market benefits. Managers may use these results to justify new product efforts and to weigh short-and longterm consequences of promotional incentives.

Under increased scrutiny from top management and shareholders, marketing managers feel the need to measure and communicate the impact of their actions on shareholder returns. In particular, how do customer value creation (through product innovation) and customer value communication (through marketing investments) affect stock returns? This paper examines conceptually and empirically how product innovations and marketing investments for such product innovations lift stock returns by improving the outlook on future cash flows. We address these questions with a large-scale econometric analysis of product innovation and associated marketing mix in the automobile industry. First, we find that adding such marketing actions to the established finance benchmark model greatly improves the explained variance in stock returns. In particular, investors react favorably to companies that launch pioneering innovations, with higher perceived quality, backed by substantial advertising support, in large and growing categories. Finally, we quantify and compare the stock return benefits of several managerial control variables. Our results highlight the stock market benefits of pioneering innovations. Compared to minor updates, pioneering innovations obtain a seven times higher impact on stock returns, and their advertising support is nine times more effective as well. Perceived quality of the new-car introduction improves the firm's stock returns while customer liking does not have a statistically significant effect. Promotional incentives have a negative effect on stock returns, suggesting that price promotions may be interpreted as a signal of demand weakness. Managers may combine these return estimates with internal data on project costs to help decide the appropriate mix of product innovation and marketing investment.
