While the benefits of being market oriented are largely accepted, a group of scholars and managers remain skeptical. Marketing scholars have sought to counter the criticisms leveled against market orientation (MO) by arguing that it has both responsive and proactive dimensions. However, few studies have empirically examined the complexity of the effects of these dimensions on firm performance. Drawing on theories of resource‐based advantage and organizational search behavior, this article advances understanding by arguing that responsive and proactive market orientations have curvilinear effects on product development performance, that their interaction may be positively related to product development performance, and that their effects on new product program performance are moderated differentially by the organizational implementation conditions and marketing function power. Survey results of 175 U.S. firms indicate support for most of the hypotheses. Specifically, whereas responsive MO has a U‐shaped relationship with new product program performance, proactive MO has an inverted U‐shaped relationship with new product program performance. Contrary to the arguments presented here, the interaction of both orientations is negatively related to new product program performance. This study finds that both orientations are needed; however, new product program performance is enhanced when one is at higher level and the other is at lower level. Finally, responsive MO is only positively related to new product program performance under specific conditions such as when strategic consensus among managers is high. On the other hand, the positive effect of proactive MO on new product program performance is further strengthened when learning orientation and marketing power are high. Overall, this study suggests that the effects of responsive and proactive MO on new product program performance are more complex than previously theoretically argued and empirically examined. 相似文献

This paper reviews the theoretical literature on bank capital regulation and analyzes some of the approaches to redesigning the 1988 Basel Accord on capital standards. The paper starts with a review of the literature on the design of the financial system and the existence of banks. It proceeds with a presentation of the market failures that justify banking regulation and an analysis of the mechanisms that have been suggested to deal with these failures. The paper then reviews the theoretical literature on bank capital regulation. This is followed by a brief history of capital regulation since the 1988 Basel Capital Accord and a presentation of both the alternative approaches that have been put forward on setting capital standards and the Basel Committee's proposal for a new capital adequacy framework. 相似文献

The authors show that an increase in international borrowing increases specialization and unemployment in a small open economy that is subject to terms‐of‐trade risks. The economy has a production advantage in the export sector. However, the size of the export sector is limited by the available funds. To insure workers against income fluctuations arising from terms‐of‐trade risks, firms in the export sector offer workers a stable wage rate with the possibility of unemployment. An increase in international borrowing increases specialization in the export sector, which leads to higher unemployment when the terms‐of‐trade shock is bad. A state‐contingent price subsidy can reduce unemployment without inefficiently reducing specialization. The results are robust to the introduction of risk‐averse firms. 相似文献

Portfolio Choice in the Presence of Housing 总被引:7,自引:0,他引:7
I show that investment in housing plays a crucial role in explainingthe patterns of cross-sectional variation in the compositionof wealth and the level of stockholdings observed in portfoliocomposition data. Due to investment in housing, younger andpoorer investors have limited financial wealth to invest instocks, which reduces the benefits of equity market participation.House price risk crowds out stockholdings, and this crowdingout effect is larger for low financial net-worth. In the modelas in the data leverage is positively correlated with stockholdings. 相似文献
