We design a project funding contract that provides optimal incentives to agents, in a setting where both principal and agent enjoy the benefits of the project in a non-rival form once completed but may differ in their valuation. To do so, we study optimal incentive payments in a dynamic principal-agent framework in which the principal cannot observe the agent’s investment, but only completed projects, and faces a Samaritan’s Dilemma: he cannot commit to terminate the contract before completion of the project. The agent decides whether to undertake a (discrete) investment or consume all received funds. We find that the optimal contract is stationary, and that either transfers equal to investment cost are incentive compatible or the cost of the contract is decreasing with the agent’s valuation of the projects. Given the intrinsic valuation of the project by the agent, he is always better off signing the contract in contraposition with the general moral hazard result.  相似文献

The core issue for the implementation of modern budget law is to optimize the satisfaction of society’s demand for public goods. The form of implementation mechanism that will best achieve this goal has thus become a major topic in the field of legal research. To go beyond the Anglo-Saxon budget model and construct a realistic path for the implementation of China’s budget law, this issue needs to be explored from the perspective of Chinese citizens in a way that safeguards the fundamental interests of the people and is premised on upholding and improving the People’s Congress system, so as to achieve a balance between internal and external budget allocation relationships. There are three routes to implementing China’s budget law: the political, the social, and the judicial. Under the first, citizens’ political identity interests are represented by deputies who oversee the budgetary powers of administrative bodies through the People’s Congress. Under the second, citizens individually or collectively participate, influence or even decide the allocation of public economic resources through dialogue, negotiation, reasoning and argument with the responsible budgetary agency in the course of the budget’s compilation, examination and approval, execution and supervision. Under the third, the establishment of a system for budgetary litigation allows citizens to participate in and supervise the implementation of the budget law, individually or collectively. This provides judicial security for the law’s implementation. These three realistic implementation routes represent the dialectical unity of concerted institutional effort aimed directly at effective implementation of budget law. Judicial interpretations of budget law implementation indicate the importance and urgency of promoting national governance capacity through reform of the legal systems governing finance and taxation. This explains the significant role of finance and taxation law in national governance.  相似文献

Informal caregiving is a critical component of the US long-term care system, but can have significant negative impacts on caregiver employment, finances, and well-being. An online survey of Colorado caregivers was piloted in 2016–17 to explore whether workplace and social policies such as access to paid family leave and public health insurance can buffer the negative financial impacts of caregiving and help caregivers to remain in the workforce. Using standardized measures, the survey assessed caregivers’ employment and financial status, well-being (physical and mental health, caregiver strain, benefits of caregiving), access to workplace supports, and covariates (e.g., caregiver demographics, health, social support, and service utilization). Ninety-five caregivers, recruited through community agency partners, completed the survey. Respondents were predominately female (89%), middle-aged (= 57), non-Hispanic White (64%) or Latino/a (22%), and caring for a parent (40%) or spouse (30%) for over one year. Half (51%) reported working full- or part-time jobs, while 16.4% had stopped working because of caregiving. In multivariate regression modeling, predictors of financial strain included the care recipients’ financial strain and the caregiver’s reduction or ceasing of work. Medicare may be protective to minimize caregivers’ need to reduce or cease work. Implications for caregivers’ ability to stay engaged in the workforce and prepare for their own retirement are explored.  相似文献

Parent–child power effectiveness was investigated during naturally occurring polyadic family conflict with young children involving three or more family members. In 35/39 families, 210 conflict sequences were identified and coded for type of power, power effectiveness, and conflict outcome. Effective use of power overall and by each partner was assessed using two methods: microscopic (target’s response to an actor’s power move during the process of conflict) and macroscopic (power moves related to conflict outcome). Actor findings revealed that parents were more effective using certain types of power microscopically (i.e., simple, legitimate, reward) and macroscopically (i.e., simple, legitimate, questioning), whereas children were more effective using reward power macroscopically. Our findings support the unique qualities of the parent–child relationship and the complex context of polyadic family conflict. The study contributes to the literature on the socialization of young children in the family context.  相似文献

The present research examined children’s anger proneness, emotion understanding, and maternal sensitivity during toddlerhood as predictors of children’s hostile attribution bias (HAB) during the later preschool years. At 2.8 years (N = 128), maternal sensitivity (e.g., child‐centered behavior) was observed during mother–child play and snack, and parents reported on children’s anger proneness. At 3.3 years, emotion understanding (i.e., ability to identify emotional expressions accurately) was measured via an interactive puppet interview. At 4.8 and 5.4 years, children's HAB was assessed via child responses to hypothetical vignettes of ambiguous peer provocations. Path models revealed that maternal sensitivity predicted fewer hostile attributions. In addition, emotion understanding and maternal sensitivity emerged as buffers against the negative effect of anger proneness on HAB. Specifically, greater anger proneness was associated with more frequent hostile attributions, but only when children had lower emotion understanding or had mothers who were less sensitive. The findings highlight the interplay between intrapersonal and interpersonal factors in early childhood that contribute to a hostile attribution bias during the preschool period.  相似文献

本文试图在社会分层视角下讨论学者群体的社会地位及其声望问题. 不可否认, 中国学术群体在当下社会经济发展以及国家战略中整体地位在不断提高; 他们在经济及社会地位等方面的获益也在日渐增多, 不过, "改革受益者"一词应该缓行。学者干预现实也并不简单预示着其权力地位乃至声望的提升. 在学者传统形象遭此损害的今天, 学术群体需要的不仅是深入的反思和自律, 因为单靠学者自律并不能从根本上解决问题. 面临复杂的社会阶层情况 ( 如阶层仇恨问题), 学者也不应该被动地接受阶层再造.  相似文献

A budget standard indicates how much a particular family living in a particular place at a particular time needs to achieve a particular standard of living. The budget includes every item that is needed to satisfy the family's individual and collective needs, priced in current retail outlets. The approach has strong intuitive appeal because it reflects how actual families do their budgeting and has been used to assess the adequacy of a wide variety of incomes and costs. This article presents new budget standards for a range of unemployed families derived from the estimates produced in the 1990s, revised to reflect new data, improved research methods and changed circumstances. The new estimates are deliberately conservative and indicate how much is needed to achieve the Minimum Income for Healthy Living standard developed by UK public health researchers. They indicate that the current level of Newstart Allowance – the main form of income support for the unemployed – is woefully inadequate. The methods used to derive the budgets have been chosen so that others can vary some of the key assumptions (e.g., about housing costs) to tailor the budgets to fit specific applications.  相似文献

Objective. This article explores cross‐sectoral alliances as mechanisms for enhancing service delivery in public education. We assess the extent to which the three economic sectors—nonprofit, for‐profit, and public—are involved in partnerships with charter schools and identify the benefits that charter schools receive from partnering with other organizations. Methods. The study utilized a qualitative approach: data collection involved interviews with charter school experts in 37 states. Results. We found that organizations from each of the three economic sectors were involved in alliances with charter schools and that these alliances offered a range of financial (e.g., facilities, salaries), political (e.g., legitimacy, credibility), and organizational (e.g., curriculum, management) benefits. Conclusions. Our findings from this exploratory study suggest that cross‐sectoral alliances have the potential to enhance the capacity of charter schools to deliver high‐quality educational services. Three hypotheses generated from the findings are also offered to guide future research on charter school alliances.  相似文献

Preschool children at two ages conversed with a toy robot during a play session. During the conversations the robot inserted either general (e.g., What?) or specific (e.g., Piggy is in what?) contingent queries in response to selected utterances. The children’s replies to these breakdowns in conversation indicated they were sensitive to the pragmatic requirements of these different types of query. By 33 months of age, the children replied to general queries with complete repetitions of their prior misunderstood utterance, and replied to specific queries with only the required constituentinformation. At 27 months of age, the children’s predominant strategy was to reply to both forms of query with complete repetitions, although the data suggest some degree of sensitivity to these different forms is also present in this younger group. These results are interpreted in terms of children’s sensitivity to Grice’s (1975) quantity rule and the potential changes in social cognition underlying children’s compliance with this rule.  相似文献

This study examined factors that affect journalists’ Twitter use behaviors based on the framework of the theory of planned behavior (TPB). A survey of Korean journalists supported that TPB is a useful theoretical framework for understanding journalists’ Twitter use behaviors. This study found that three TPB variables – positive attitudes, subjective norm, and perceived behavioral control – are positively associated with journalists’ general Twitter use (i.e., time spent using Twitter). More importantly, beyond looking at journalists’ general Twitter use, this study expands the literature by distinguishing between expressive Twitter use (e.g., tweeting messages) and consumptive Twitter use (e.g., reading others’ tweets). Results showed that journalists’ attitudes, subjective norms, and perceived behavioral controls were associated differently depending on patterns of expressive and consumptive Twitter usage. Given the role of professional journalists in society, their ways of using Twitter may have a profound impact on the ecology of journalism. Contributing to the literature of the theory of planned behavior by extending its explanatory power to professional journalists’ Twitter usage, the results of this study suggest that future research on journalists’ Twitter use should pay more attention to how Twitter is employed within the journalistic context.  相似文献

Some insurance markets are characterized by “advantageous selection”, that is, ex-post risk and coverage are negatively correlated. We show that expectation-based loss aversion as in K?szegi and Rabin (Quarterly Journal of Economics, 121(4), 1133–1165, 2006; The American Economic Review, 97(4), 1047–1073, 2007) provides a natural explanation for this phenomenon in environments in which risk aversion models do not, e.g., when agents face modest-scale risks and/or in absence of moral hazard. More exposure to risk has two competing effects on an agent’s willingness to pay for insurance: a positive effect, as in standard expected utility models; and a negative one, due to a reference effect. We determine conditions under which an insurance provider optimally sets a high price at which only low risk agents buy.  相似文献

After observing ostracism or social exclusion, older children, adolescents and adults report decreased satisfaction of the need for control. Attempting to regain control can motivate aggression in ostracized adults. Research has shown that the onset of ostracism’s harmful effects on children’s behavior is at preschool age. We investigated whether preschoolers would exert more control after witnessing ostracism. A sample of 53 children (Mage = 5 years, 5 months) first watched priming videos either showing ostracism or not. Subsequently, they participated in two ball games. In both of the games (order counterbalanced), children could control the flow of a ball’s motion, either live between two people (i.e., social control) or between two bars on a laptop screen (i.e., non‐social control). Overall, children understood social exclusion when it was displayed in the videos. We found an effect of observed ostracism only on social control. Four‐ to five‐year‐old boys who witnessed ostracism stopped a ball game between two persons longer than boys who did not witness ostracism. Our results suggest that observing social exclusion elevates young boys’ need for control over a social situation. Girls showed a different pattern but their responses did not differ significantly between ostracism and non‐ostracism conditions.  相似文献

Children’s social status in China includes both informal (e.g., social preference) and formal (e.g., class leader) statuses. This study examines the associations among caregivers’ characteristics, children’s characteristics, children’s social preference, and being a class leader by using multiple sources of information (caregiver reports, self‐ratings, sociometric methods, and achievement data). The participants were 1,926 fourth‐ to ninth‐ graders (Mage = 12.7; 49.7% males) and their primary caregivers. The caregivers’ characteristics were found to be related more closely to class leader than to social preference. Both higher children’s interpersonal character and academic achievement were associated with higher social preference and class leader; however, academic achievement showed stronger relationships with both types of status than interpersonal character. The children’s characteristics mediated the associations between caregivers’ characteristics and children’s social statuses. The grade difference test showed that interpersonal character had a stronger association with social preference, and academic achievement had a stronger association with class leader in secondary school than in primary school. The results suggest that children’s characteristics (especially academic achievement) are strongly related to Chinese children’s social preference and being a class leader. In addition, the potential role of caregivers’ characteristics and the influence of child age are noteworthy.  相似文献

Borgeraas E, Dahl E. Low income and ‘poverty lines’ in Norway: a comparison of three concepts
Int J Soc Welfare 2010: 19: 73–83 © 2008 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. In this article we address the question of how well three concepts of ‘poverty’ correspond with each other. We have compared three different measures of ‘poverty’ in Norway: income poverty and two measures of a minimum budget standard, one scientifically and one politically defined. The three measures rest on different underlying concepts, serve different purposes and yield significantly different poverty lines. If followed by the municipal social services, the governmental norms for social benefits will, paradoxically, leave the beneficiaries in income poverty as defined by that same government. The most generous poverty line of all three measures is provided by the minimum budget standard developed by the National Institute for Consumer Research in Norway, which rests on the assumption that a household's income has to give a sustainable financial situation in the longer run. Neither of the two other poverty measures have this property. All numbers pertain to the year 2005. Some political and practical implications of the findings are discussed.  相似文献

We argue in this article that if government bonds are counted as part of private wealth, government budget deficits are a major cause of inflation, and the method chosen to finance the deficits (e.g., borrowing or monetary expansion) is of secondary importance. To illustrate this point we use a simple portfolio model that is then incorporated into a model of the Australian economy. The full model is specified in continuous time, and it is estimated by the full information maximum likelihood method (FIML) it is then used to simulate a number of fiscal shocks.  相似文献

This paper investigates the potential impact of the income stabilisation tool (IST), currently introduced in the European Common Agricultural Policy to reduce farmers’ income risks using Italian agriculture as case study. The paper extends the existing literature by investigating the effects of two implementation issues: level of aggregation of mutual funds (MF); definition of farmers’ contribution (i.e. premium) to MF. We use a simulation approach based on a FADN panel data set of 3421 farms over a period of 7 years to investigate effects on (i) farm-level income variability, (ii) the expected level and variability of indemnifications at the level of mutual funds and (iii) the distribution of net benefits from this policy instrument across the farm population. We find that the introduction of the IST would lead to a significant reduction of income variability in Italian agriculture. Our results support the establishment of a national mutual fund due to the high volatility of indemnification levels at more disaggregated (e.g. regional or sectoral) levels. In addition, our results propose that farmers’ contribution to mutual funds, i.e. premiums paid, should be modulated according to farm size as this reduces the inequality of the distribution of benefits of such tool within the farm population.  相似文献

Young ( N = 57), middle-aged ( N = 57), and older adults ( N = 47) were presented with an editorial that argued in favor of their age group's economic interests (e.g., their privilege was fair; their disadvantage was unfair) or against their age group's economic interests (e.g., their privilege was unfair; their disadvantage was fair). Participants completed measures of perceived age discrimination, attributions for outcomes, and support for age-based spending. Unfavorable intergenerational comparisons elicited higher perceived age discrimination in middle-aged adults, and more support among all age groups for funding to middle-aged adults compared to favorable comparisons. Young and older adults reported more age discrimination than middle-aged adults regardless of comparison type. Age group status consequences for responses to the intergenerational conflict debate are discussed.  相似文献

Hawley's influential resource control theory (RCT) posits that both coercive and prosocial strategies may yield social dominance, as indexed by resource control. Based on differences in youths’ relative use of these strategies, RCT a priori defines five distinct subtypes. Several studies by Hawley and colleagues have revealed substantial differences between subtypes in terms of obtained resource control and various social characteristics (e.g., agreeableness). The present longitudinal study (N = 394; M age = 10.3; SD = 0.5) expands on previous work. Firstly, because several items used to assess strategies in RCT appear to confound strategy use with the resulting benefits (resource control), we disentangled between strategy use as such and obtained resource control. Secondly whereas previous work has been exclusively cross‐sectional, the present study was longitudinal. ANOVAs comparing subgroups provided support for some core tenets of RCT, but not for others. For instance, bistrategic children scored high on both resource control and perceived popularity. However, bistrategics engaged in elevated bullying, and whereas Hawley asserts that they are proficient in balancing ‘getting ahead’ with ‘getting along’, their behavior appeared to evoke clear negative reactions in the peer group at large. Findings also showed that non‐controllers did not experience more negative outcomes than their peers across all domains.  相似文献

Efforts to increase involvement of citizens in their communities are now widespread. We discuss key forms of community involvement, such as community service and volunteerism, broadly, and educational initiatives that promote involvement (e.g., service–learning courses) more specifically. There are benefits to be achieved by the promotion of involvement, but also potential drawbacks. As an example of one approach to investigating community involvement, we review research on the interactive influence of person–centered functional variables (e.g., motives) and situation–centered structural variables (e.g., program features) on prosocial action. Ultimately, we call for greater attention to be paid to all of the constituent groups in the community involvement spectrum and the necessarily respectful and equitable relationships that must be forged among them.  相似文献

We investigated person (sex, aggression level), context (witness type, victim reactions), and person × context effects on children's anticipated moral emotions following hypothetical acts of aggression against a peer. Children (N = 378, mean age = 11.3 years) were presented a series of hypothetical vignettes in which the presence of witnesses (no witnesses/most liked classmates/all of the class) and victim's reactions (neutral/ sad/ angry) were manipulated. The results indicated several person effects (e.g., girls anticipated more guilt and shame but less pride than boys; aggressiveness was related to less guilt and shame), as well as context effects (e.g., anticipated shame depended on who witnessed the situation and the emotional reactions of the victim). However, person × context effects predominated. The overall pattern of results indicated that girls and low‐aggressive children were more sensitive to contextual cues than boys and high‐aggressive children. The findings support the importance of a person × context approach to understanding the emotional reactions of different children in different situations.  相似文献
