Using daily data on margins and variation margins for all clearing members of the Chicago Mercantile Exchange, we analyze the clearing house exposure to the risk of default by clearing members. We find that the major source of default risk for a clearing member is proprietary trading rather than trading by customers. Additionally, we show that extreme losses suffered by important clearing firms tend to cluster, which raises systemic risk concerns. Finally, we discuss how private insurance could be used to cover the loss from defaults by clearing members. 相似文献

This paper describes international statistical standards in the context of the product life cycle. To set the stage, the historical evolution of standardization is traced from the Xia Dynasty of China to the present. The transition from local standards geared for manufacturing to national and then international standards is highlighted with acceptance sampling standards. International statistical standards now cover a broad range of topics beyond acceptance sampling, so a scheme is needed to organize them into a coherent structure. The product Life cycle provides just such a framework. The product Life cycle (which is subsumed to include service, as well) is partitioned into four main "megaphases", namely: conception, development, delivery and maturity and death. Each megaphase is linked to relevant statistical methods in general and statistical standards in particular. A gap analysis identifies potential future directions of statistical standards developments and the attendant role that statisticians can continue to play in this arena. 相似文献

This paper presents spatial models of logrolling in the EU. It analyzes the Commission appointment, logrolling and policy-making processes under the EU's principal legislative procedures: the consultation, cooperation and codecision procedures. The theory characterizes equilibrium EU policies and sets of successful policies, i.e., sets of policies that can become EU policy during the logrolling and policy-making processes. It also determines countries' optimal nomination strategies and countries' and legislators' optimal voting strategies during the Commission appointment process. It concludes that the EU institutions provide opportunities for efficient and stable exchanges of votes. 相似文献

This paper analyses the behaviour of an economy characterized by staggered wage contract rules specified in nominal and in real terms. It is shown that staggered contracts in real terms imply complex eigenvalues which cause oscillatory paths both for output and unemployment and stonger output losses in response to an unexpected and permanent fall in the growth rate of money supply. 相似文献

Previous research on the impact of chief executive officer (CEO) locus of control is mainly based on simple and partial mappings of bivariate associations between CEO locus of control and organizational outcomes. In addition, distinct substreams have emerged in which intricately related phenomena are studied separately. to overcome this fragmentation and polarization, we provide and empirically test an integrative framework based on previously tested hypotheses on the impact of CEO locus of control. Our approach differs from prior research in two ways. First, it simultaneously takes account of strategic choice and firm performance in order to assess the extent to which strategy mediates the relationship between CEO locus of control and organizational performance. Second, we consider the CEO to be both a formulator and implementor of organizational strategies. Besides the observation that CEO locus of control seems to matter a lot in terms of explaining organizational performance in the present sample, our results demonstrate that an integrative approach increases our insight into the impact of CEO locus of control by revealing why some CEOs achieve higher organizational performance than others. 相似文献

Past research indicates that the effect of TMT functional diversity on firm performance is equivocal. We address this issue by focusing on the integrative role of the CEO, postulating that the CEO's expertise and background characteristics affect the TMT functional diversity–firm performance relationship, because of their impact on the exchange and integration of distributed knowledge within the TMT. Using a dataset of 33 Dutch and Belgian Information Technology firms we investigate the moderating role of three sets of CEO characteristics (functional background, status as founder, and shared experience with the other TMT members) on the relationship between TMT functional diversity and firm performance. Our results reveal that CEO and TMT characteristics do interact in realizing the potential advantages of distributed TMT functional expertise. 相似文献

The Weibull distribution plays a central role in modeling duration data. Its maximum likelihood estimator is very sensitive
to outliers. We propose three robust and explicit Weibull parameter estimators: the quantile least squares, the repeated median
and the median/Q
n
estimator. We derive their breakdown point, influence function, asymptotic variance and study their finite sample properties
in a Monte Carlo study. The methods are illustrated on real lifetime data affected by a recording error. 相似文献
