This study explores the effects of task structure and leader power on participative leadership across Australian, African, Papua-New Guinea and Pacific Island managers. Managers in all national groups are more participative in situations of low structure and low power than for high structure and high power, respectively. Participation in situations of low structure and low power declines in the order: Australia, Africa, Papua-New Guinea, Pacific Islands. It is argued that this effect is an instrumental effect of managerial education, rather than being culturally determined. the Vroom-Yetton leadership methodology is used to measure participation levels. Subjects are a total of 150 middle-level managers attending management education courses. 相似文献

In the economic literature, reciprocity is typically studied in situations of repeated interaction between two individuals. It refers to one individual rewarding kind acts of the other or punishing hostile acts. In contrast, this paper studies indirect reciprocity, where a cooperative action is rewarded by a third actor, not involved in the original exchange. We provide experimental evidence on indirect reciprocity. The experiment is based on the ‘repeated helping game’ developed by Nowak and Sigmund (J. Theoret. Biol. 194 (1998) 561; Nature 393 (1998) 573), involving random pairing in large groups. Pairs consist of a donor and a recipient. Donors decide whether or not to provide costly ‘help’ to the recipients they are matched with, based on information about the recipient's behavior in encounters with third parties. We observe clear evidence of indirect reciprocity. Many decision-makers respond to the information about previous decisions (whether or not to help others) of the recipients. In our experiments, this indirect reciprocity is largely based on norms about how often the recipient should have helped others in the past. We show that these norms develop similarly within groups of interacting subjects, but distinctly across groups. This leads to the emergence of group norms. 相似文献

In recent work on non-cooperative network formation star-shaped networks play an important role. In a particular theoretical
model of Bala and Goyal (2000) center-sponsored stars are the only strict Nash networks. In testing this theoretical model,
Falk and Kosfeld (2003) do not find experimental evidence that players select the center-sponsored star. Based on a slight
modification of Bala and Goyal’s model, we design a network formation experiment in which, depending on link costs, periphery-sponsored
stars and the empty network are the only strict Nash networks. We observe that almost all groups not only reach a strict Nash
network once but also switch the center player in periphery-sponsored stars several times. The main innovation in our experiment
is to use a continuous time framework which we believe to be a more realistic setting to study behavior in network formation
situations and which makes coordination on stars much easier than simultaneous strategy adaptation in discrete time.

Exchange rates have deviated substantially and idiosyncratically from purchasing power parity (PPP) since the breakdown of Bretton Woods. In this paper, a model incorporating both traditional PPP and financial market variables is constructed and tested on the US dollar's six G7 exchange rates during the floating rate era. Empirical tests show that the model's common set of variables—with consistent signs—can explain the divergent behavior of G7 exchange rates during 1973.2–90.2. Idiosyncracies are reflected in different subsets of the model's variables entering significantly into each exchange rate's regression; the existence of stable relationships is demonstrated by the equations' co-integration. 相似文献

ABSTRACTWhile online communities may enhance firm performance, they commonly fail to retain members. To address this challenge, scholars and managers call for the use of gamification. However, despite gamification’s growing use in online communities, insight into its effect on member experience and behaviours remain limited. We hypothesise that gamification affects member-perceived distributive and procedural justice. In experimental studies, we assess the impact of in-gamification perceived justice on member contributions. We find that while high in-gamification perceived procedural justice acts as a necessary prerequisite for member contributions, high distributive justice can reduce game-related uncertainty, thereby rendering gamified practices less fun, particularly for low-engaged community members that tend to value rewards. We add to the literature by (a) pinpointing the core role of perceived justice in the persistence of online communities, and (b) unveiling that high distributive justice can lead gamification to backfire in online communities by affecting member experience and contributions. 相似文献

The removal of trade barriers has encouraged the entry of new competitors into formerly protected markets. This situation creates pressure on many small and medium enterprises (SMEs) in emerging economies such as Tanzania. Using a survey method and cross-sectional research design, the research examines three dimensions of entrepreneurial orientation (EO), namely: pro-activeness, risk-taking and competitive aggressiveness. Understanding their relationships and variance may help to improve our ability to explain SME performance. The findings contribute to how SME performance in emerging economies can be enhanced to enable SMEs to face challenges posed by competitor influx in the context of an open market economy. The findings indicate a strong relationship between EO dimensions and performance, with risk-taking and competitive aggressiveness moderating the effect of pro-activeness. The proposed model could predict 72% of the variance explained in SME performance. 相似文献

Methods and tools for integrated assessment of land use policies on sustainable development in developing countries 总被引:4,自引:0,他引:4

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem. 相似文献

This study analyzes the impact of bank relationships on a firm's borrowing costs. We find that a firm's borrowing costs decrease with relationship strength, proxied by the share of bank debt provided by the lender. Borrowing costs, however, rise with relationship length. While the increase over time is weak on average, bank‐dependent borrowers face a substantial premium after several relationship years. Switching the lender initially leads to only a small price discount on average. However, the discount is considerable for borrowers that switch and had a strong relationship with their previous lender. Our results suggest that close lending relationships lead to benefits for the firm, but may also imply hold‐up costs in the long term. 相似文献

This article aims to quantify to what extent collaborative strategies are more effective than internal or organization‐level actions to green supply chains. In this regard, the impact of decisions made at different stages of a supply chain in a product's carbon footprint is quantified. Organizational and product carbon footprints are calculated using the Compound Method Based on Financial Accounts (MC3). The results underline that concentrating reduction efforts in some stages of the supply chain is more effective than implementing individual actions by the participants. Collaboration among the participants is needed to decide what practices are implemented, at what stage they are needed and how they are to be implemented. This article adds to the literature on supply chains and sustainability. Previous research suggests that collaborative strategies have great potential for reducing the carbon footprint of products, while indicating the need for empirical research to support this statement.
