Market Orientation and the New Product Paradox   总被引:2,自引:0,他引:2  
The extant literature shows that the strength of the market orientation–performance relationship decays as the terminal measure of performance shifts from new product success to profitability to market share. As Day (1999) concluded, a broader nomological inquiry is needed to more fully understand the nature and limits of market orientation's effects. This suggests that a broader nomological inquiry is needed to fully understand the nature and limits of market orientation's effects.
Utilizing a national sample of marketing executives, the present study's purpose is to build a fuller understanding of the effects of market orientation on firm performance. Its structural equations model includes measures of new product success, profitability, and market share.
The research reinforces a strong positive relationship between market orientation and new product success. The expanded nomological network under study, however, implies barriers to market orientation's effectiveness. First, market-orientation-inspired increases in the priority firms place on "breakthrough" learning without commensurate increases in the priority placed on "breakthrough" innovation capabilities can boomerang and negatively impact new product success. Second, market-orientation-inspired new product development programs that are unable to increase market share can negatively impact profitability. These gatekeepers to the success of market orientation underscore the need for firms to coordinate a strong market orientation with resources and capabilities that increase the effectiveness of the marketing function. Without such coordination, the positive effect of market orientation on new product success may be limited to incremental innovations, and the overall effect of successful new products on profitability may be limited.  相似文献

We investigate how the prevalence of materialistic bank CEOs has evolved over time, and how risk management policies, non-CEO executives’ behavior and tail risk vary with CEO materialism. We document that the proportion of banks run by materialistic CEOs increased significantly from 1994 to 2004, that the strength of risk management functions is significantly lower for banks with materialistic CEOs, and that non-CEO executives in banks with materialistic CEOs insider trade more aggressively around government intervention during the financial crisis. Finally, we find that banks with materialistic CEOs have significantly more downside tail risk relative to banks with non-materialistic CEOs.  相似文献

Enterprise risk management (ERM) is a process that manages all risks in an integrated, holistic fashion by controlling and coordinating any offsetting risks across the enterprise. This research investigates whether the adoption of the ERM approach affects firms' cost of equity capital. We restrict our analysis to the U.S. insurance industry to control for unobservable differences in business models and risk exposures across industries. We simultaneously model firms' adoption of ERM and the effect of ERM on the cost of capital. We find that ERM adoption significantly reduces firm's cost of capital. Our results suggest that cost of capital benefits are one answer to the question how ERM can create value.  相似文献

The new standard for the accounting of insurance contracts (IFRS 17) will entail substantial changes for the insurance industry. In the following article the new standard is critically analyzed. First and foremost the coming valuation model, the so-called building block approach, is presented which will be the basis for all insurance contracts within the scope of IFRS 17. (For certain insurance contracts, especially those with direct participation features, or for less complex or short-term insurance contracts, there are some modifications.) To be more precise, IFRS 17 introduces an enterprise-specific valuation approach that is grounded on the so-called fulfilment value. This fulfilment value is determined by four separate building blocks (fulfilment-cashflow, discount rate, risk margin and contractual service margin), which will be addressed in detail. Finally, major changes in performed accounting practices that insurance enterprises are confronted with and will have to adapt to in their financial statements and accounts are pointed out.  相似文献

This study examines whether firms engage in income-decreasing real earnings management before open market stock repurchases to reduce the cost of stock buybacks. In the short run, managers have the ability to underproduce inventory and increase discretionary expenditures, thus decreasing current period earnings. We find that managers engage in both of these activities before repurchasing their firms’ shares, especially the latter. Also, companies increase their discretionary spending before making repurchases to a greater extent following the passage of the Sarbanes–Oxley Act of 2002 as well as when they are financially healthy and have high marginal tax rates. Finally, we document that firms with the most income-decreasing real earnings management experience the largest positive abnormal returns during the subsequent period. Our findings highlight the importance of considering firms’ use of real operating decisions, as opposed to just opportunistic disclosure practices, around significant corporate events, such as the repurchase of their own stock.  相似文献

This paper analyzes the importance of distinguishing between watch-preceded and direct rating changes for the credit default swap (CDS) market by examining a total of 2991 rating change announcements, 1526 watchlist placement announcements, and 430 rating affirmations following watchlist placements. The results show that watch-preceded downgrades do not lead to significant CDS market reactions, while direct downgrades are associated with a significant increase in CDS spread levels. Likewise, we document that watchlist placements for downgrade lead to increases in firms’ CDS spreads. CDS markets do not react to rating upgrades but watchlist placements for upgrade result in an immediate decrease in CDS spreads. Rating affirmations following watchlist placements for downgrade lead to slight reductions in CDS spreads, while affirmations following watchlist placements for upgrade have no effect on CDS spreads. These findings demonstrate the importance for empirical research on the interaction between credit markets and rating announcements to differentiate between watch-preceded and direct rating changes, particularly for rating downgrades.  相似文献

One of the major challenges involved in risk aggregation is the lack of risk data. Recently, researchers have found that mapping financial statements into risk types is a satisfactory way to resolve the problem of data shortage and inconsistency. Nevertheless, ignoring off-balance sheet (OBS) items has so far been regarded as the usual practice in risk aggregation, which may lead to deviations in conclusions. Hence, we improve the financial statements based risk aggregation framework by mapping OBS items into risk types. Based on 487 quarterly financial statements from all 16 listed Chinese commercial banks over the period 2007–2014, we empirically study whether the overall impact of OBS activities and the individual impact of each of the OBS risk types on total risk depend on bank size. Moreover, this research divides the sample into two subsets, during and after the subprime crisis, to find out how the subprime crisis affects risks of Chinese banks. Our empirical results show that although OBS credit risk is positively linked to total risk while OBS operational risk is negatively linked to total risk for both large and small banks, the overall impact of OBS activities on total risk depends on bank size. The overall OBS activities are positively related to the large bank’s total risk while they are negatively related to the small bank’s total risk. Besides, we also found that it is the increase of liquidity risk and market risk that leads to the larger total risk of Chinese banks during the subprime crisis.  相似文献

Using a strategic merger sample that covers the period from 1985 to 2011, we find that the acquirer’s stock price firm-specific information, the new information created by investors about the value of firm fundamentals, increases the positive sensitivity of strategic merger investment to the acquirer’s Q; the target’s stock price firm-specific information increases the negative sensitivity of merger investment to the target’s Q. These results suggest that managers learn from financial markets in identifying strategic merger investment opportunities by transferring assets from poorly managed firms to well managed firms. In addition, the target’s stock price firm-specific information itself increases the acquisition size, indicating that informed acquirer managers are more likely to take out large merger investment. Last but not the least, stock price informativeness increases merger synergies and post-merger performance, suggesting that informed managers make better merger investment that increases shareholder value. Our study contributes to the recent increasing stream of studies on managerial learning from the market.  相似文献
