This paper studies the impacts of income distribution on the efficiency of trade mechanism and rationing of agents who are priced out of trade in a dynamic search model with two-sided asymmetric information. Buyers and sellers have asymmetric information about valuations and incomes respectively. In such a frictional environment, the effects of several variants of changes in income distribution on efficiency of trading mechanism and the population of rationed buyers and sellers are elaborated.  相似文献

Managing the introduction of nonindigenous species is becoming a major goal of policy-makers at regional, national and international scales. Here we investigate, at the national level, the ideal design and expected net benefits of a risk assessment program for evaluating the desirability of nonindigenous species imports. We show how to enhance the statistical rigor of such a system by correcting a common non-random sampling problem encountered in the data. This correction enables model output to be interpreted in an economically relevant way and facilitates a theoretically rigorous characterization of the balance between trade and nonindigenous species establishment risk. Using reptiles and amphibians imported to the U.S. as a case study, we characterize economic outcomes over a range of cases and demonstrate substantial expected returns to such a screening program, relative to the current effectively open-door policy. Our results are informative for the current debate in the U.S. about whether to require federal agencies to apply risk assessment before allowing a species for import. The framework presented decomposes a complex argument about risk management into component economic and statistical parts, allowing for debate and improved understanding over each element to inform the overall program in a transparent fashion.  相似文献

Wohnungsdesorganisation bei Sucht - Chaotische Wohnverh?ltnisse lassen sich oft auf eine Suchterkrankung zurückführen. Dabei kann man einen deutlichen Unterschied zwischen Wohnungen von Menschen mit einer Kaufsucht und denen von Menschen mit psychischen St?rungen und Verhaltensst?rungen durch psychotrope Substanzen beobachten.  相似文献

This conceptual article suggests a reexamination of current governance structures, specifically those of unitary boards after the financial crisis of 2008. We suggest that the existing governance structures are based on an outdated paradigm of business, rooted in economics. We propose an alternative paradigm, a more humanistic paradigm, which allows conceiving alternative, network-oriented governance structures. As hierarchical firms grow larger and more complex, the risk of failure increases from biases, errors, and missing data in communication and control systems. These problems are exacerbated by information overload on senior managers, directors, and their respective regulators. In contrast to traditional corporate governance, network governance introduces a division of power via multiple boards, checks and balances, and active stakeholder engagement. We argue that those features could have prevented the stresses and failures of financial firms in 2008, since they were anticipated by both individuals within firms and external commentators. However, those exposed to risks possessed insufficient influence in either governing and/or regulating firms to take corrective action.  相似文献

This paper describes the development and validation of a measure of organizational investments in social capital (OISC). The scale development process is carried out over three stages (item generation, scale purification, scale validation), with two separate data collection phases involving a total of 735 working adults from multiple and diverse service-related workplace settings. As such, the data provide evidence for the face, content, discriminant, convergent and nomological validity, dimensionality and reliability of the OISC measure. The OISC measure is a concise, unidimensional scale that has the potential for significant usage in the development and testing of theory, as well as practical application in retail and other service provision contexts.  相似文献

Taking multidimensional ethics scale approach, this article describes an empirical survey of top managers’ moral decision-making patterns and their change from 1994 to 2004 during morally problematic situations in the Finnish context. The survey questionnaire consisted of four moral dilemmas and a multidimensional scale with six ethical dimensions: justice, deontology, relativism, utilitarianism, egoism and female ethics. The managers evaluated their decision-making in the problems using the multidimensional ethics scale. Altogether 880 questionnaires were analysed statistically. It is concluded that relying on the utilitarian principles is a core ethical evaluation criterion amongst top business managers in Finland. This study proves that managers’ moral decision-making patterns change over time. According to the results of this research, managers’ moral decision-making became more multidimensional during the study period. The change is explained by (1) the inclusion of female ethics items in the scale which allows managers to show more diversity in their decision- making, (2) the change in the Finnish economic context from depression to economic prosperity and growth during the study period, which is conducive to the spread of post materialist values, such as the importance of social relations and (3) the increasing public discussion of the importance ethical issues in business.  相似文献
