We study network games in which each player wishes to connect his source and sink, and the cost of each edge is shared among its users either equally (in Fair Connection Games—FCG's) or arbitrarily (in General Connection Games—GCG's). We study the existence and quality of strong equilibria (SE)—strategy profiles from which no coalition can improve the cost of each of its members—in these settings. We show that SE always exist in the following games: (1) Single source and sink FCG's and GCG's. (2) Single source multiple sinks FCG's and GCG's on series parallel graphs. (3) Multi source and sink FCG's on extension parallel graphs. As for the quality of the SE, in any FCG with n players, the cost of any SE is bounded by H(n) (i.e., the harmonic sum), contrasted with the Θ(n) price of anarchy. For any GCG, any SE is optimal. 相似文献

Economics has typically been the social science of choice to inform public policy and policymakers. In the current paper we
contemplate the role behavioral science can play in enlightening policymakers. In particular, we provide some examples of
research that has and can be used to inform policy, reflect on the kind of behavioral science that is important for policy,
and approaches for convincing policy-makers to listen to behavioral scientists. We suggest that policymakers are unlikely
to invest the time translating behavioral research into its policy implications, and researchers interested in influencing
public policy must therefore invest substantial effort, and direct that effort differently than in standard research practices. 相似文献

This study examines how directors make decisions that involve shareholders and other stakeholders. Using vignettes derived from seminal court cases, we construct an index of directors' shareholderism as a general orientation on this issue. In a survey of the entire population of directors and CEOs in public corporations in one country, we find that directors' personal values and roles play an important part in their decisions. Directors and CEOs are more pro‐shareholder the more they endorse entrepreneurial values—specifically, higher achievement, power, and self‐direction values and lower universalism values. While employee representative directors exhibit a lower baseline level of shareholder orientation, they nonetheless often side with shareholders. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This special issue concentrates on the global economic downturn that reached its lowest point in late 2008. Signals of an impending crisis started in 2007 with a wave of insolvent subprime mortgages in the United States, but the seeds were planted years earlier. In its scope, length, and countries affected, this downturn is the worst in over 70 years. It is changing and will continue to change local and global business and economic environments. This issue aims to learn from past mistakes and better understand the new environment. Each part contains five articles and an introduction. Part I has a global perspective; Part II focuses on specific national economies. © 2011 Wiley Periodicals, Inc. 相似文献

This paper investigates sequential manufacturer–retailer price determination and channel performance under possible misrepresentation by one member of its privately known cost. To the standard double marginalization game, we add a preliminary stage where the manufacturer (alternately the retailer) announces its privately known constant marginal cost. We prove that the manufacturer has no incentive to misrepresent its cost, and we give respective sufficient conditions on the demand function for the retailer to overreport and to underreport costs. Depending on the shape of the demand function, opportunistic behavior by the retailer may lower or raise the manufacturer’s profit and channel performance. 相似文献

This paper asks whether the asset pricing fluctuations induced by the presence of costly external finance are empirically plausible. To accomplish this, we incorporate costly external finance into a dynamic stochastic general equilibrium model and explore its implications for the properties of the returns on key financial assets, such as stocks, bonds and risky loans. We find that the mean and volatility of the equity premium, although small, are significantly higher than those in comparable adjustment cost models. However, we also show that these results require a procyclical financing premium, a property that seems at odds with the data. 相似文献

Response surface methodology (Box-Behnken design) was used to optimize the seasoning ingredients of popped popcorn. Children’s liking of seasoned popcorn was also determined by 120 school children. The results indicated that seasoning of popcorn with fish protein powder and omega-3 fish oil could produce accepted snacks that would be more nutritious than the widely consumed regular popcorn. Fortification of popcorn with 9% fish protein powder and/or 6% omega-3 fish oil did not influence the sensory attributes of the prototypes. Liking test revealed that children in the age range of 6 to 12 years liked the selected fortified products. This fortification also provided another avenue for cereal snack food diversification and might be a healthy option to boost children’s nutritional intake and to increase fish protein consumption. Such products are good choices for health-conscious consumers. 相似文献

Inclusive markets are key to fostering female entrepreneurship, and the microfinance sector has recognized and acted on this. Existing research has studied how institutions and organizational factors facilitate the process by which microfinance and other financial intermediaries tackle gender-based financial exclusion. But while the role of cultural institutions has been recognized as important, little research has systematically integrated culture in the study of gender-based financial exclusion. We posit that language is a cultural institution that influences the extent to which financial intermediaries are successful in outreaching women and supporting female entrepreneurship. Inspired by a performativity approach, we develop a set of hypotheses that delineate how a specific feature of language, gender marking in grammar, moderates the role of institutional (state capacity) and organizational (NGO status and global ties) factors in shaping microfinance outreach to women. Using the ratio of female to male borrowers in 2361 microfinance organizations from 115 countries during the period 1995–2015, we confirm that market inclusion of women depends on organizational and institutional factors, and that gender marking in grammar influences those relationships. 相似文献

Recent studies suggest the relationship between dynamic capabilities and competitive advantage may be jointly affected by organizational and environmental factors. We enrich this nascent perspective by developing a configurational theoretical framework – underpinned by the mechanism of strategic fit – wherein dynamic capabilities lead to a competitive advantage when they support a strategic orientation appropriate for the levels of dynamism and munificence in the environment. Results of a fuzzy‐set Qualitative Comparative Analysis using primary data show that dynamic capabilities lead to a competitive advantage in dynamic, munificent environments by enabling the combination of differentiation and low‐cost orientations. In stable, non‐munificent environments, dynamic capabilities are effective in support of a low‐cost orientation. The central insight of this study is that the relationship between dynamic capabilities and competitive advantage is contingent upon the strategic fit between organizational and environmental factors, contributing to a more rigorous and configurational dynamic capabilities view. 相似文献
