Starting from the premise that workers have ‘property rights’ in their jobs, this article considers ways in which British unfair dismissal legislation might be said to uphold such rights. The evidence indicates that remedies of compensation and re-employment afford minimal property rights to unfairly dismissed workers. 相似文献

We consider the M/M/1-queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the result. 相似文献

The availability of a stochastic repairable system depends on the failure behaviour and on repair strategies. In this paper,
we deal with a general repair model for a system using auxiliary counting processes and corresponding intensities which include
various degrees of repair (between minimal repair and perfect repair). For determining the model parameters we need estimators
depending on failure times and repair times: maximum likelihood (ML) estimator and Bayes estimators are considered. Special
results are obtained by the use of Weibull-type intensities and random observation times. 相似文献

What accounts for the diversity and limited concentration that has long characterized the organization of the advertising agency industry? This question is addressed by treating an advertising agency as a multiproduct firm. The firm's product line or service mix is defined in terms of the set of different media categories where an agency places the advertising messages that it creates on behalf of its clients. Evidence is presented indicating that the structure of demand and costs in the advertising agency industry conforms to the conditions that MacDonald and Slivinski showed were required for an industry to sustain an equilibrium with diversified firms. Building on this framework, we formulate a set of three hypotheses relating to the realization of product-specific scale and scope economies. The first two hypotheses posit that given low fixed costs and minimal entry barriers, both media-specific scale and scope economies are available and can be exploited by relatively small-size agencies. The third hypothesis suggests that large agencies may experience diseconomies of scope as a consequence of excessive diversification induced by two pervasive industry institutional phenomena: (1) “bundling” of agency services to match client demand for a mix of media advertising, and (2) “conflict policy,” which prohibits an agency from serving competing accounts and operates as a mobility constraint. Utilizing a multiproduct cost function, we estimate media-specific scale and scope economies for a cross section of 401 U.S. agencies in 1987. The results obtained support the set of three hypotheses outlined above. The paper concludes with a discussion of the implications of these findings for the restructuring currently underway in this industry. 相似文献

Financial distress precedes bankruptcy. Most financial distress models actually rely on bankruptcy data, which is easier to
obtain. We obtained a dataset of financially distressed but not yet bankrupt companies supplying a major auto manufacturer.
An early warning model successfully discriminated between these distressed companies and a second group of similar but healthy
companies. Previous researchers argue the matched-sample design, on which some earlier models were built, causes bias. To
test for bias, the dataset was partitioned into smaller samples that approach equal groupings. We statistically confirm the
presence of a bias and describe its impact on estimated classification rates. 相似文献
