The ability of new product development (NPD) teams to generate ideas and develop high‐quality concepts for new products is a crucial determinant of NPD success. Although prior research in this area has developed various interventions to enhance the ability of teams to generate ideas, such interventions have limited impact on innovation management theory and practice. Partly, this is because of practical reasons: The interventions are often costly and impractical. However, there are also more fundamental, theoretical issues regarding these interventions: Knowledge of which interventions are effective in what situations is lacking. Even more importantly, there is no theory (or empirical evidence) about the effects of these interventions on the success of developing initial ideas into concepts. Together, this has caused the usefulness of these interventions for NPD teams to be uncertain at best. To remedy this situation, this study focuses on a costless and easy‐to‐implement intervention: suspending group debate. Suspending group debate refers to a team idea generation and concept development process in which groups debate a problem, ideas for solutions are generated individually, and these ideas are debated and developed into concepts collectively. The authors developed a new theory about the impact of suspending group debate on idea generation and on further concept development. Specifically, they argue that suspending group debate causes groups to generate a higher number of ideas, a higher number of original ideas, and a more diverse set of ideas, but that only the number of original ideas and the diversity of the set of ideas will translate into higher concept quality. The authors also developed new theory about when suspending group debate is especially effective. Specifically, they argue that suspending group debate is especially effective when at least one group member is low on extraversion. This theory is tested using an experimental design in which groups generated ideas and developed concepts for a specific organizational problem. Some groups suspend group debate, while others do not. Results show that suspending group debate indeed causes groups to generate a higher number of ideas, a higher number of original ideas, and a more diverse set of ideas. Importantly, results demonstrate that the effects of suspending group debate are more pronounced for groups with one or more group members that are low on extraversion. Furthermore, suspending group debate also affects concept quality, mediated by the number of original ideas and the diversity of ideas that groups generate (and thus not by the sheer number of ideas generated). Specifically, results show that both the diversity of the idea set as well as the number of original ideas positively influence the innovativeness of the final concept, while only the diversity of the idea set influences the comprehensiveness of the final concept. 相似文献

The views expressed in this paper are those of the authors alone and in no way represent those of the institutions they represent. This paper calibrates a stylized national policy model of the U.S. dairy industry to analyze the effects of liberalizing the tariff quota policy. It is important to distinguish in-quota, over-quota, out-of-quota and nonquota imports. A framework to model quota underfill with out-of-quota imports is highlighted. To endogenize quota underfill and still account for out-of-quota imports, one needs to depict the marginal private benefits of imports under the quota and the corresponding marginal cost curve. The total transaction costs of the import quota scheme can be calculated. This framework is well suited for handling shocks because a change in in-quota or out-of-quota tariffs or a shift in the excess supply/demand curves affects marginal benefits, while a change in the quota affects the marginal cost of imports. We show regime switches affect trade liberalization and that a decrease in tariffs or an increase in quotas may have little effect without liberalizing both instruments. A component approach to model the sector has endogenous government-controlled class prices. An increase in imports of one product can result in an increase in the prices of other nontraded dairy products. This is because component prices change and so impact government-controlled class prices. Nous étalonnons un modèle de programme national stylisé du secteur laitier étatsunien pour analyser les effets d'une libéralisation de lapolitique des contingents tarifaires. Il est important de faire la distinction entre importation à l'intérieur du contingent, excédentaire au contingent, hors-contingent et non visée par un contingent. Nous mettons en évidence un cadre pour modéliser la portion non utilisée d'un contingent en présence d'importations hors-contingent. Pour endogénéiser la portion non utilisée d'un contingent tout en gardant en compte les importations hors-contingent, il faut décrire les avantages privés marginaux des importations prévues dans le contingent et la courbe des coûts marginaux correspondants. Les coûts transactionnels totaux des régimes de contingents tarifaires 4aG l'importation peuvent être calculés. Ce cadre convient bien pour absorber les chocs, du fait qu‘un changement des tarifs douaniers imposés aux importations intra-contingent ou aux importations hors-contingent, ou encore un déplacement de la courbe d'offres/demandes excédentaires, se répercute sur les bénéfices marginaux des exportations, alors qu‘un changement du régime de contingentement le fait sur les coûts marginaux. Nous démontrons que des changements de régime influent sur la libéralisation du commerce extérieur et qu'une réduction des tarifs douaniers ou une augmentation des contingents peuvent n'avoir que peu d'effets sans une libéralisation réelle des deux instruments. Une solution utilisant les composants laitiers pour modéliser le secteur comporte un contrôle endogène de l'État sur les prix par catégoric de produits. Un accroissement des importations visant un produit donné peut se propager aux prix d'autres produits laitiers non visés par les échanges commerciaux. Une telle réaction vient du fait que les prix des composants changent et qu'ils peuvent se réverbérer sur les prix par catégorie réglementés par l'État. 相似文献

Abstract. This paper studies the design and effects of monetary and fiscal policy in the euro area. To do so, a stylized two‐region model of monetary and fiscal policy rules in the EMU is built. We analyse how monetary and fiscal rules affect the adjustment dynamics in the model. Both the effects on the individual countries and on the EMU aggregate economy are studied. Three aspects play an important role in the analysis: (i) the consequences of alternative monetary and fiscal policy rules, (ii) the consequences of asymmetries between EMU countries (asymmetries in macroeconomic shocks and macroeconomic structures), and (iii) the role of alternative degrees of backward‐ and forward‐looking behaviour in consumer decisions and inflation expectations. 相似文献

abstract The emergent literature on dynamic capabilities and their role in value creation is riddled with inconsistencies, overlapping definitions, and outright contradictions. Yet, the theoretical and practical importance of developing and applying dynamic capabilities to sustain a firm's competitive advantage in complex and volatile external environments has catapulted this issue to the forefront of the research agendas of many scholars. In this paper, we offer a definition of dynamic capabilities, separating them from substantive capabilities as well as from their antecedents and consequences. We also present a set of propositions that outline (1) how substantive capabilities and dynamic capabilities are related to one another, (2) how this relationship is moderated by organizational knowledge and skills, (3) how organizational age affects the speed of utilization of dynamic capabilities and the learning mode used in organizational change, and (4) how organizational knowledge and market dynamism affect the likely value of dynamic capabilities. Our discussion and model help to delineate key differences in the dynamic capabilities that new ventures and established companies have, revealing a key source of strategic heterogeneity between these firms. 相似文献

The objectives of this study of household grain consumption in China are to update previous estimates of consumption parameters, to look at the effect of urbanization on grain consumption and to compare household demand patterns across the region. Household grain consumption is divided into two categories: direct and indirect grain consumption. Demand systems are estimated for four consumer groups, rural, town, city and large city, respectively, using data from the 1991 rural and urban household surveys undertaken by China's State Statistical Bureau. The impact on grain consumption of income, price and urbanization is particularly elaborated. 相似文献

The tactics, strategies, and behaviors thatwere suggested by Niccolo Machiavelli in The Prince (1513) have become synonymous withmanipulative and unethical behavior. AlthoughMachiavelli wrote to the politician, hiswritings have since been expanded to describebusiness leaders as well as general behavior. The research we report examined theMachiavellian tendencies of current collegestudents and compares the results to theseminal study by Christie and Geis (1970). Theresearch reported here examined thecontemporary student's propensity towardMachiavellianism distinguished by major fieldof study and by gender. The data werecollected from students at colleges located inthe Midwest and the Southwest. We reportfindings that are similar to Christie and Geisand extend the trend line suggested by theirresearch. We believe these findings provideinsight for understanding the dynamics ofcontemporary college students and suggest acontinuing societal movement towardMachiavellian behavior. 相似文献

Provision of safe injecting rooms (SIRs), needle exchanges and other harm minimisation schemes reduce mortality and other health risks that illicit drug users experience. However, SIRs diminish incentives to refrain from the use of drugs by reducing the risk of a key harmful consequence of use, namely the user's death. Moreover, such harm minimisation efforts are socially costly. Economic approaches to drug management balance benefits from harm minimisation against policy costs and the costs associated with a failure of community drug abstinence. This article shows that the economic case for SIRs disappears with conservative assumptions about adverse incentive effects of reduced mortality risks even when only modest weight is placed on drug abstinence objectives. 相似文献

Since the mid‐1980s U.S. domestic firms have faced significant increases in foreign‐based (i.e., import) competition as reductions in barriers to international commerce have resulted in markets and industries becoming increasingly global. Despite the growing and widespread importance of foreign‐based competition, the influence that such competition may exert on corporate diversification strategy is a question largely overlooked in the strategic management literature. This paper examines the impact of foreign‐based competition in a firm's core business on both the level and nature of a firm's diversification strategy at the corporate level in a panel dataset of U.S. firms over the period 1985–94. Our findings provide the first evidence that increased foreign‐based competition is indeed a statistically significant factor explaining both the reduced business‐level diversity and the increased strategic focus of U.S. firms that has been widely perceived over the past two decades.

This article provides an overview of mandated commodity programs in California, and summarizes and interprets existing evidence on their economic impacts. The analysis draws upon the recent book edited by the authors: The Economics of Commodity Promotion Programs: Lessons from California . New York: Peter Lang Publishing, April 2005. The book documents the institutional arrangements, summarizes the history of recent litigation, and presents the results of a number of benefit–cost studies of mandated commodity programs in California. The overwhelming conclusion from the studies reported in the article is that the programs have been very profitable for California's agricultural producers. 相似文献
