The paradox of insolvent enterprises regularly contracting new debts is the motivation behind this research. Statistical tests carried out on a sample of 62 manufacturing firms show that the financial behaviour of these enterprises is mainly explained by two factors: the rate of asset immobilization and the manager's social capital. The impact of the first factor is due to the asset capacity to serve guarantees, and the impact of the second is inherent to the possibility that enables relational networks to get around norms or to reach informal circuits and alternative sources of financing. The latter aspect is the beginning of the answer to the insolvency and indebtedness paradox. This result denotes the coexistence of two parallel dimensions in the Cameroon business environment. Besides the formal sphere, where the lack of confidence and readability between the actors pushes financial backers to excesses of prudence, subsists an informal universe where confidence, loyalty and solidarity seem to cement business relationships. However, the economic rationality of actors in these networks remains problematic.  相似文献

Biases in meeting opportunities have been recently shown to play a key role for the emergence of homophily in social networks (see Currarini et al., 2009). The aim of this paper is to provide a simple microfoundation of these biases in a model where the size and type-composition of the meeting pools are shaped by agents׳ socialization decisions. In particular, agents either inbreed (direct search only to similar types) or outbreed (direct search to population at large). When outbreeding is costly, this is shown to induce stark equilibrium behavior of a threshold type: agents “inbreed” (i.e. mostly meet their own type) if, and only if, their group is above certain size. We show that this threshold equilibrium generates patterns of in-group and cross-group ties that are consistent with empirical evidence of homophily in two paradigmatic instances: high school friendships and interethnic marriages.  相似文献

This paper identifies several positive synergies between social protection programmes and enhanced entitlements to food. One function of social protection is to manage or reduce vulnerability. Several instruments are reviewed – weather-indexed insurance, public works programmes, emergency food aid and buffer stock management – which aim to stabilise income and access to food across good and bad years, or between the harvest and the hungry season. Other social protection instruments aim to raise household income and crop production, for instance agricultural input subsidies or input trade fairs, as well as public works projects that construct or maintain physical infrastructure such as rural feeder roads. This paper also argues that entitlements to food can be strengthened if social justice principles are introduced to the design and delivery of social protection programmes. Examples reviewed include rights-based approaches such as employment guarantee schemes, community-based targeting and demand-driven accountability mechanisms. The paper concludes by arguing for a comprehensive approach to social protection that will achieve sustainable food security, by combining interventions that stabilise income or food production with those that raise income or food production, and are designed and delivered in ways that enhance social justice.  相似文献

We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors’ expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an agent׳s social influence on the long-run group opinion is increasing in network centrality and decreasing in conformity. Concerning efficiency of information aggregation or “wisdom” of the society, it turns out that misrepresentation of opinions need not undermine wisdom, but may even enhance it. Given the network, we provide the optimal distribution of conformity levels in the society and show which agents should be more conforming in order to increase wisdom.  相似文献

This article examines how social identity links institutional pressures and audit quality. Combining institutional theory and social identity theory, we theoretically argue that the interaction between social and institutional forces shapes audit quality. Through an analysis of Chinese audit firms from 2000 to 2007, we show that isomorphic imitation has a more significant effect on firms belonging to the same-identity group than firms across cross-identity groups; foreign-affiliated audit firms are more willing to conform to normative pressure from professional networks than local firms; and foreign-affiliated firms are coerced to adapt to the local government’s expectation, particularly when they have a geographically concentrated customer base. We further reveal that a larger customer base attenuates within-identity group imitation but strengthens cross-identity group imitation. The results shed light on the role of social identity in shaping conformity in the audit industry, thus contributing to international convergence–divergence literature and institutional theory.  相似文献

Changes in rural land use to reduce flood risk are encouraged by governments in many countries, but they may face considerable opposition by land managers. Local participative processes are thought to help overcome opposition. This article presents an evaluation of an intensive participative process set up between land managers and governmental agencies following two severe floods in the transboundary Bowmont–Glen catchment in Scotland and England. A combination of interviews and documentary analysis is used. The research demonstrates that the participative process contributed to greater uptake of rural land use change and improved compliance with existing environmental policies. There were nevertheless low levels of social learning amongst participants. Two institutional designs for improving policy implementation are presented.  相似文献

Social coupons (SCs) (e.g., Groupon) differ from traditional or regular coupons (RCs) in that they require consumers to make a prepayment to receive substantive discounts. As the general rule of SCs prohibits double-promotion, SC consumers tend to engage in certain avoidance behaviors when experiencing another promotion (i.e., specially priced for selected items). The results across two scenario-based experiments reveal that SC consumers (vs. RC consumers) have a greater tendency to avoid specially priced items when redeeming a coupon for hedonic consumptions, but not for utilitarian consumptions. Such avoidance is due to one’s motivation to minimize the perception of deal waste.  相似文献

A growing number of researchers have examined the effects of personalized advertising in traditional media, however, little has been known about personalized advertising on Facebook. The primary objectives of this research are threefold: (1) Develop a comprehensive model that captures the effects of perceived personalized ads on Facebook on customer attitudinal and behavioral reactions (ad credibility, ad avoidance, ad skepticism, ad attitude, and behavioral intention) to the ad; (2) Test hypothesized relationships using two data sets collected through an online survey; and (3) Develop appropriate customer segments based on personal views of personalized ads on Facebook. The paper reveals that eleven out of thirteen hypotheses are supported and that three market segments are identified including Ad Lovers, Ad Accommodators, and Ad Haters. The paper concludes with conclusion and discussions highlighting managerial and research implications.  相似文献

This paper is devoted to propose an approach to implement the idea of extended peer knowledge to environmental governance by means of engaging the «extended peer communities». Socially robust knowledge relies on transparency and citizen participation. These two underlying elements take the form of both assessment and post-assessment decision support systems. Initially, during the assessment process citizens and stakeholders are engaged in the framing, proposal of alternatives, and evaluation criteria. Then the analysts assessed the alternatives proposed by means of DSS. Then, in a second stage, the analysts inspired in the idea of transparency, gave back the assessment result to the «extended peer community» who were able to give their opinion regarding the results and suggest potential parametric changes that were used for sensitivity analyses. The authors explore the proposed extended peer communities’ knowledge sharing for environmental governance assessment using a case study applied to a sustainable mobility planning process carried out in Tenerife (Canary Islands). The results gathered highlight that this approach is of use for guaranteeing the robustness of complex environmental decisions under high levels of uncertainty.  相似文献

This study examines the relationships among relevant service quality dimensions of Internet service providers (ISP) and their customers’ perceived value, trust and commitment. Data was collected from residential Internet users in Thailand. The final usable sample size was 1507. The analyses include segmenting ISPs’ customers on the basis of their usage pattern and evaluating their perceptions of Internet service quality dimensions. In addition, several alternatives models were compared using structural equation modelling to confirm the mediation effects. An ISP’s service quality is influenced by the following four dimensions (a) network quality, (b) customer service and technical support, (c) information quality and (d) security and privacy. The findings reveal that while all dimensions have positive effects on trust, only network quality, information support and privacy influence customer value significantly and information support is the only dimension which is directly related to commitment. Additionally, the effects of customer service and information support on value vary across customers of different Internet usage patterns. The contribution of the present paper stems from the simultaneous modelling of a range of mediation effects which can better help explain the impact of service quality dimensions on customers’ cognitive and affective evaluations in high-tech service settings.  相似文献
