This research concerns how costs and benefits affect the voluntary provision of threshold public goods. Cadsby and Maynes (J. Public Econ. 71:53–73, 1999) hypothesized that the difference between the value and cost of such a good, its net reward, influences the likelihood of provision. Croson and Marks (Exp. Econ. 2:239–259, 2000) focused on the ratio of group payoff to total cost, the step return. We find that step return is the best predictor overall, although net reward has some impact, negatively affecting the probability of provision with inexperienced participants and positively affecting it with experienced participants.  相似文献

Abstract

Foreign direct investment (FDI) can deliver benefits beyond the provision of capital, such as efficiency gains. We argue that the theorised positive effects of economic linkage are reduced when linkages are based on natural resources. Domestic elite coalitions supporting reform are also weaker in countries with extensive natural resources. Kazakhstan and Azerbaijan have high-value natural resources and significant FDI, making them most likely cases for reform. Kyrgyzstan is a contrasting case as it has few natural resources. We find that the institutional reforms we would anticipate because of linkages have not occurred and those that exist are often cosmetic.  相似文献

The study examines narrative data from in-depth, semi-structured interviews with 25 women in a medium security prison with the hope of deepening the knowledge base related to women’s beliefs about their mental health problems, mental health care during incarceration, and especially their experiences with psychotropic medication. The findings highlight the functional role of psychotropic medication in the lives of incarcerated women, while also emphasizing problems with limited access to prescribers, preferred medications, and other forms of mental health treatment. Trauma, substance use, and the impact of medication use on sense of self all emerged as interfacing with quality of life.  相似文献

Critical social scientific research holds that credit–debt is a principal economic and governing relation in contemporary economy and society, but largely neglects money’s role in indebted life. Drawing on qualitative research in the payday loan market in the United Kingdom, the paper shows that borrowers typically relate to loans in monetary rather than financial terms and incorporate them into practices of payment, spending and online banking. To analyse how indebted life is variously experienced and enacted through money, the concept of money culture is developed to refer to money’s culture, money’s meanings and money’s affects. Borrowers enter into and negotiate payday loans through a digitally mediated money culture that both mobilizes and runs counter to money’s powerful fictions as circulating universal equivalent and calculative means of account.  相似文献

This paper identifies the business constraints that are most binding for firm performance. Using panel methods on novel quarterly Ugandan business climate data, we exploit perceived changes in business climate constraints to account for changes in firm performance. Not all identified constraints are binding for firm performance. Macroeconomic instability, demand stability, access to finance, corruption/bribery, and weather variability are found to be binding constraints. Firms’ expectations about future performance outcomes are associated with current perceptions about these constraints, alleviating endogeneity concerns to some extent. While taxation constraints are usually highly ranked, we do not find evidence linking them to firm performance.  相似文献

This article suggests that the futuwwa articulated by Shihāb al-Dīn ‘Umar al-Suhrawardī (1144–1234) created a paradigm of exclusion and inclusion for late medieval Anatolian urban confraternities. This largely faith-based construct was developed in the Seljuk capital of Konya and reduplicated in futuwwa treatises that were composed in Armenian, Persian and Turkish in the region. The multi-cultural, multi-lingual, multi-religious cultural environment of the late medieval Anatolian city provided an opportunity and, possibly, a necessity for futuwwa associations to draw boundaries around their associations. It is uniquely through the study of the city as a unit that we will be able to understand the huge cultural and religious transformations that were taking place in Anatolia during the late medieval period. Study of futuwwa associations as regulating urban populations provides a window of insight into the ways in which groups of men attempted to define themselves in juxtaposition with others.  相似文献

The UK investigative interview model advocates police officers use the cognitive interview (CI). However, research has indicated that many officers perceive the CI as too cumbersome, complex, and time consuming for some types of crime. With this in mind we investigate the efficacy of two CI procedures, which have been substantially modified to enhance forensic practicability and retain the empirically demonstrated CI superiority effect. Employing the mock witness paradigm, both are compared to the procedure currently taught to UK police officers. Participant's memorial performance revealed no differences across interview conditions for the amount of correct and incorrect recall. However, those interviewed using the modified procedures confabulated less and were more accurate. Considering type of information recalled (person, action, object, and surrounding), no differences were found across conditions for correct or confabulated type recall. However, the two modified CIs elicited fewer incorrect person and object information items. Further, they were shorter in duration than the current procedure. Hence, for frontline less serious crime, or in time critical situations, the modified procedures may be viable alternatives. These findings and their implications are discussed.  相似文献
