A simple model of employment contracting is employed to examine the effectiveness of just‐cause provisions in alleviating employer opportunism in two types of efficiency wage contracts—standard contracts, in which wages exceed the worker's marginal contribution, and deferred wages, which are paid after a period of tenure in the firm. It is argued that just‐cause employment policies are necessary and sufficient to prevent employer opportunism when standard efficiency wages are utilized. However, just‐cause policies are not sufficient to deter employer opportunism when employment contracts are of the delayed‐payment type. In these contracts, other contractual provisions, such as severance provisions, are also necessary. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

We review evidence on the impacts of CGIAR research published since 2000 in order to provide insight into how successfully the CGIAR Centers have been in pursuing the System’s core missions. Our review suggests that CGIAR research contributions in crop genetic improvement, pest management, natural resources management, and policy research have, in the aggregate, yielded strongly positive impacts relative to investment, and appear likely to continue doing so. Crop genetic improvement research stands out as having had the most profound documented positive impacts. Substantial evidence exists that other research areas within the CGIAR have had large beneficial impacts although often locally and nationally rather than internationally. However, the “right-time, right-place” nature of successful policy research and the relatively limited geographic scale of much natural resource management research often limits the overall scale of impacts of these programmatic thrusts vis-à-vis genetic improvement research. We conclude that given the evidence available, the CGIAR’s portfolio of research allocations has become overly skewed toward natural resource management and policy research over time. Hence, restoring somewhat the share of resources allocated to crop genetic improvement is warranted. In addition, the CGIAR needs to prioritize impact assessment of resource management and policy research to deepen its understanding of the social and environmental impacts of its work. 相似文献

Expenditures on agricultural research in the public sector, including the International Agricultural Research Centers (IARCs) have stagnated and in some cases, declined sharply in recent years. This has focused attention on issues of efficiency of agricultural research systems, especially the number, size, scope, type, and locations of their programs. This paper examines the issue of research efficiency through a case study of wheat improvement research in developing countries. The basic premise of this study is that the optimal level of research investment should be determined in a global model that incorporates direct research spill‐ins. An analytical framework is developed to determine the threshold levels of crop production in a country (or a region within a country) needed to justify crop improvement research programs of different sizes in the presence of spill‐ins from abroad. Spill‐in coefficients are estimated from yield performance of varieties of different origins grown across a range of environments. The model is then applied to analyze the efficiency of current investments in 69 wheat improvement research programs in 35 developing countries. A major conclusion of the paper is that given the magnitude of potential spill‐ins from the international research system, many wheat research programs could significantly increase the efficiency of resource use by reducing the size of their wheat research programs and focusing on the screening of varieties developed elsewhere. ©2000 Elsevier Science B.V.

Regulation imposes compliance demands on business, but these controls by no means ensure that corporations will act ethically. Externally imposed controls by government or industry are prompts intended to move organizations to engage in a moral minimum. Such efforts are typically reactionary corrective measures, often crafted and applied after an ethical scandal occurs, and thereby offer limited effectiveness in providing systemic change. To provide insight on internally driven controls, this article examines how a newer form of monetized self-regulation, referred to as inverted moral markets, might be leveraged to motivate corporate ethical behavior. Inverted moral market (IMM) operations target firms suspected of unethical action, providing a type of market whistleblowing. Such activities are monetized through the sale of information to investors and by short selling. Rather than a desire to build moral strength, IMM firms are motivated by self-interest and profit. They can potentially ‘do good’ by imposing self-correction within the market, but without virtuous intent. We explore IMMs and the varied impacts their activities may have on the functioning of the overall market. We argue that a more balanced approach between internal and external regulation may enhance the environment for moral balance in a capitalist market system. 相似文献

This paper examines the influence of social power on consumers' propensity to defer choice. Based on the notion that elevated power reduces regret anticipation—the fear of making a wrong choice—it is proposed that power influences the extent of choice deferral by reducing consumers' susceptibility to anticipated regret. Because of the regret-based mechanism, power can increase or decrease consumers' propensity to defer choice, depending upon the situational factors that are associated with anticipated regret, such as salience of regret, outcome reversibility (e.g., return policy), and locus-of-regret (postponing vs. choosing now). Using different manipulations of power, seven studies provide consistent support for the proposed effects and show that situational factors and marketing strategies can induce, turn off, or even reverse the effect of power on deferral. Theoretical contributions and managerial implications are discussed. 相似文献

Fixed versus flexible election terms: explaining innovation in the timing of Canada’s election cycle
This paper argues that there is an efficiency gain underlying the recent adoption of legislation calling for a fixed 4-year governing term by the federal and most provincial governments in Canada. The efficiency gain arises from foreclosing an externality produced by the Canadian constitutional provision that sets a maximum length for a legislative term (5 years) while allowing the governing party (through the Governor General) to dissolve the House early. Because the opportunistic use of surprise can improve the governing party’s probability of winning, strategic choice can lead to elections being held at times that most disadvantage the incumbent’s rivals. Evidence from Canada is introduced suggesting that federal elections became less predictable through successive reductions in the campaign time given to competitors, thus raising the cost of this externality. The same reasoning suggests that the party most likely to propose this legislative innovation will be the party in opposition rather than in power and/or the new leader of an established party facing loss in the upcoming election. By fulfilling the fixed term even when it could benefit by calling the election early, the party establishes a precedent that raises the political cost to others of cancelling the fixed term legislation. 相似文献

This paper examines the valuation implications of greenhouse gas (GHG) emissions allowances. We posit that the value of a firm's bank of emission allowances has two components that are likely to be positively valued by the capital market: (1) an asset value component; and (2) a real option value component. Since the necessary data to examine this research hypothesis in the setting of GHG emission allowances is not yet available, we test our conjecture by examining the value relevance of sulfur dioxide (SO2) emission allowances held by US electric utilities. Empirical results reveal that the capital market assigns a positive price to a firm's bank of SO2 emission allowances, consistent with the argument that emission allowances have, at least, an asset value component that is assigned a positive price by the market. We also find weak evidence consistent with the market assigning a real option value to the allowance banks. 相似文献

Organizations must target talented applicants, who will often be demographically diverse, to attract the most competent and competitive workforce possible. Despite the bottom‐line implications of attracting the best and brightest, surprisingly little is known about how and why diversity recruitment strategies affect recruitment outcomes (e.g., job‐pursuit intentions). To gain insight into this question, we conducted an initial experimental study (N = 194) to test the premise that other‐group orientation moderates the relationship between perceived organizational value of diversity and job‐pursuit intentions. In a follow‐up experiment (N = 255), identity affirmation was examined as the mediating mechanism for the interaction observed in the first study. Mediated moderation analyses supported the proposed model. Collectively, the studies indicate that job seekers high in other‐group orientation are more intent on pursuing employment with organizations deemed to value diversity because they feel that their salient identities are likely to be affirmed. No such indirect effect is present for those lower in other‐group orientation. 相似文献

This paper identifies that Information and Communication Technology (ICT) has a negative effect on software piracy rates in
addition to consolidating prior research that economic development and the cultural dimension of individualism also negatively
affect piracy rates. Using data for 59 countries from 2000 to 2005, the findings show that economic well-being, individualism
and technology development as measured by ICT expenditures explain between 70% and 82% of the variation in software piracy
rates during this period. The research results provide important implications for policy makers and business practitioners
to help reduce software piracy.

Museums and heritage tourism sites are highly curated places of memory work whose function is the assembling and ordering of space and narrative to contour visitors’ experiences of the past. Variations in such experiences within and between sites, however, necessitates a method that: (1) captures how guides, visitors, and exhibits interact within spaces when representing and performing history and (2) allows researchers to document those variations. We developed narrative mapping, a mobile and geographically sensitive form of participant observation, to enable museum scholars and professionals to systematically capture, visualize, and interpret tendencies and variations in the content, affective qualities, and spatial arrangements of museum narratives over multiple sites and across multiple tours at the same site. Two antebellum plantation museum case studies, Laura Plantation in Louisiana and Virginia’s Berkeley Plantation, demonstrate the method’s utility in documenting how stories are spatially configured and materially enlivened in order to analyze the ways enslaved persons are placed within these narratives. 相似文献
