In an effort to improve the small sample properties of generalized method of moments (GMM) estimators, a number of alternative estimators have been suggested. These include empirical likelihood (EL), continuous updating, and exponential tilting estimators. We show that these estimators share a common structure, being members of a class of generalized empirical likelihood (GEL) estimators. We use this structure to compare their higher order asymptotic properties. We find that GEL has no asymptotic bias due to correlation of the moment functions with their Jacobian, eliminating an important source of bias for GMM in models with endogeneity. We also find that EL has no asymptotic bias from estimating the optimal weight matrix, eliminating a further important source of bias for GMM in panel data models. We give bias corrected GMM and GEL estimators. We also show that bias corrected EL inherits the higher order property of maximum likelihood, that it is higher order asymptotically efficient relative to the other bias corrected estimators. 相似文献

This article examines an AHRC ‘Co-Design and Co-Production’ project focussed on the decision-making processes within the ‘heritage ecology’. The project involved three UK universities and a range of heritage institutions and community organisations. The project set out to empower community organisations through an emphasis upon deliberative democracy. Heritage is conceptualised as public value because it is used to define identity and belonging in civil society. Network governance theory is used to characterise the operational capabilities and the decision-making environment in the heritage ecology. The article argues that the public value of heritage is realised through network governance when ‘human elements’, such as emotional value are authentically and legitimately represented in deliberative processes. 相似文献

We directly compare two institutions, a family compact—a parent makes a transfer to her parent in anticipation of a possible future gift from her children—with a pay-as-you-go, public pension system, in a life cycle model with endogenous fertility wherein children are valued both as consumption and investment goods. Absent intragenerational heterogeneity, we show that a benevolent government has no welfare justification for introducing public pensions alongside thriving family compacts since the former is associated with inefficiently low fertility. This result hinges critically on a fiscal externality—the inability of middle age agents to internalize the impact of their fertility decisions on old-age transfers under a public pension system. With homogeneous agents, a strong-enough negative aggregate shock to middle-age incomes destroys all family compacts, and in such a setting, an optimal public pension system cannot enter. This suggests the raison d’être for social security must lie outside of its function as a pension system—specifically its redistributive function which emerges with heterogeneous agents. In a simple modification of our benchmark model—one that allows for idiosyncratic frictions to compact formation such as differences in infertility/mating status—a welfare-enhancing role for a public pension system emerges; such systems may flourish even when family compacts cannot. 相似文献

The question of how an auditor's going-concern disclosure affects a client's future operations has long troubled the auditing profession. In an attempt to provide further understanding of this issue, we introduce Discrete-Time Survival Analysis (DTSA) to examine the aftermath of 231 first-time going-concern disclosures on clients' subsequent continuance. DTSA represents a significant refinement over traditional ordinary least squares (OLS) and logistic (LOGIT) regression in that it provides not only a probability estimate, but also an estimate of the timing of the event occurrence. The addition of this extra dimension (event timing) aids decision makers by providing more complete information about event probabilities. Consistent with the “self-fulfilling prophecy effect,” the risk profiles developed from DTSA indicate that the first year subsequent to the initial going-concern disclosure was the most dangerous in terms of risk of bankruptcy. However, after the first year, the incidence of bankruptcy decreases significantly. Thus, DTSA is able to provide a richer perspective on this perplexing issue than previously considered. 相似文献

Modern agricultural production typically requires large quantities of chemical pesticides, a potential source of both environmental and human harm. Previous social science research has suggested that environmental problems such as those associated with pesticide use may begin to decline at higher levels of economic development. Using fixed effects models, we examine whether this possible relationship holds within nations and over time. This study draws on data from the World Bank as well as pesticide use data from the Food and Agriculture Organization of the United Nations to examine the relationship between pesticide use and economic development within nations from 1990 to 2014. The findings are considered from theoretical perspectives in environmental sociology on the drivers of environmental impacts: the treadmill of production theory, structural human ecology, ecological modernization theory, and the environmental Kuznets curve hypothesis. The results of this study show a positive relationship between economic development and pesticide consumption over time, with no decline in use at higher levels of economic development. Thus, they generally support the claims made by treadmill of production and structural human ecology. 相似文献

Critical standpoint: Leaders of color advancing racial equality in predominantly white organizations
Brad R. Fulton Michelle Oyakawa Richard L. Wood 《Nonprofit management & leadership》2019,30(2):255-276
Organizations are often core sites for the production and perpetuation of social inequality. Although the United States is becoming more racially diverse, organizational elites remain disproportionately white, and this mismatch contributes to increasing racial inequality. This article examines whether and how leaders of color within predominantly white organizations can help their organizations address racial inequality. Our analysis uses data from a national study of politically oriented civic organizations and ethnographic fieldwork within one predominantly white organization. We draw on institutional work research, the outsider‐within concept, and insights from critical whiteness theory to explain how leaders of color can use their position and “critical standpoint” to help guide their organization toward advancing racial equality. The qualitative analysis shows how such leaders, when empowered, help their organization address race internally by (a) providing alternatives to white‐dominated perspectives, (b) developing tools to educate white members about racial inequality, and (c) identifying and addressing barriers to becoming a more racially diverse organization. The qualitative analysis also shows how leaders of color help their organization address race externally by (a) sharing personal narratives about living in a white‐dominated society and (b) brokering collaborations with organizations led by people of color. This research has implications for organizations seeking to promote social equality: Organizational leaders from marginalized status groups can help their organizations address social inequality, if those leaders possess a critical standpoint and sufficient organizational authority. 相似文献

This paper provides a sociological model of the key transnational political and economic forces that are shaping the 'global football field'. The model draws upon, and significantly extends, the theory of the 'global field' developed previously by Robertson. The model features four quadrants, each of which contains a dominant operating principle, an 'elemental reference point', and an 'elemental theme'. The quadrants contain, first, neo-liberalism, associated with the individual and elite football clubs; second, neo-mercantilism, associated with nation-states and national football systems; third, international relations, associated with international governing bodies; and fourth, global civil society, associated with diverse institutions that pursue human development and/or social justice. We examine some of the interactions and tensions between the major institutional and ideological forces across the four quadrants. We conclude by examining how the weakest quadrant, featuring global civil society, may gain greater prominence within football. In broad terms, we argue that our four-fold model may be utilized to map and to examine other substantive research fields with reference to globalization. 相似文献

Neighborhood social capital-resources inherent within community networks-has been identified as a potential facilitator of personal well-being. We test hypotheses concerning how neighborhood social capital moderates the influence of parenting strain on mastery (individuals' understanding of their ability to control personal life circumstances) for female primary caregivers of children. First, we test how different forms of neighborhood social capital-social support, social leverage (information exchange), informal social control, and neighborhood organization participation-modify the association between parenting strain and mastery. Second, we test whether such moderation depends on one's access to these forms via neighbor ties. Analyses of Los Angeles Family and Neighborhood Survey data (N = 765) indicate that the negative relationship between parenting strain and mastery worsens as informal social control increases. Social support and informal social control, however, buffer this parenting strain-mastery relationship when caregivers have stronger ties to neighbors. Our findings implicate mechanisms of "negative social capital" and warrant more nuanced considerations of neighborhood social capital's health-promoting potential. 相似文献

After the waves of change resulting from the biological revolution in psychiatry gradually receded, interpersonal approaches
to the study of serious mental illness, long in decline, once again regained currency. The renewed emphasis on subjectivity,
spurred in large measure by the burgeoning recovery movement, brought the lived experience of illness to the forefront of
research. However, inquiries into psychotherapy paid little heed to the interior world of therapists immersed in the longterm
treatment of severe mental illness. Their experiences failed to garner much attention despite the adoption of intersubjective
perspectives in broader interpretations of psychotherapy. The purpose of this essay is to look anew at the dynamics that arise
in the psychotherapy of major mental illness and recast light on the struggles of both clients and clinicians through an intensive
case presentation exploring the contours of identity. 相似文献
