Law without justice: The dilemmas of formalization and fairness in the legalistic organization

There is growing evidence of a litigation mentality rampant in organizations, which has created a legalistic mindset in many managers. Increasingly, managerial decisions are becoming dominated by a concern for what is legally defensible at the expense of broader social considerations such as justice and fairness. The papers in this special issue explore how this legalistic mindset has created new organizational and social dilemmas, and situations of law whithout justice.     

Vergleich des verallgemeinerten nichtzentralent-Tests mit dem Binomialtest

Zusammenfassung Es sei {F _,(x); –<<, >0} mitF _,(x)=F((x–)/)–F(x) eine standardisierte Verteilungsfunktion — die Familie der zulässigen Verteilungsfunktionen. Der (früher eingeführte) verallgemeinerte nichtzentralet-Test für die Hypothese {PP ₀} mitP:=F _,(x ₀) gegen die Alternative {P>P ₀} zum Niveau wird mit dem entsprechenden nichtparametrischen Test (Test für die Hypothese {pP ₀} über den Parameterp einer Binomialverteilung gegen die Alternative {p>P ₀}) verglichen. Für dent-Test wird die relative asymptotische Effizienz bestimmt.Beide Tests lassen sich als Tests für das zur WahrscheinlichkeitP ₀ gehörende Quantil einer Verteilungsfunktion interpretieren. Der klassische zentrale Student-Test ergibt sich als Spezialfall (F(x)=(x),P ₀=0,5).

Summary Let {F _,(x);–<<, >0} withF _,(x ₀):=F((x–)/–F(x) a standarized distribution function — the family of admissible distribution functions. The (earlier introduced) generalized noncentralt-test for the hypothesis {PP ₀} withP:=F _,(x ₀) against the alternative {P>P ₀} at level of significance is compared with the corresponding nonparametric test (Binomial test). The relative asymptotic efficiency of thet-test is determined. Both kinds of tests can be interpreted as quantiltests. In caseF(x)=(x),P ₀=0,5 one gets the classical central Student-test.

     

Una nuova caratterizzatione dell'ammissibilità nella teoria delle decisioni

In questo lavoro viene fornita una nuova caratterizzazione dell'ammissibilità attraverso un adeguato uso della nozione di ammissibilità parziale. Questa caratterizzazione consente di affrontare le questioni riguardanti la completezza della classe delle decisioni ammissibiliti sotto condizioni «maneggevoli». Fornisce inoltre un approccio unificante al problema della completezza che consente di derivare, come casi particolari, alcuni risultati già noti nella letteratura sull'argomento.

In this paper a new characterization of admissibility is given for general decision problems. It is based on an adequate use of the notion of partial admissibility.A general decision problem is usually synthetized by a triplet (, , ) where is the states (or parameters) space, the set of available decisions and is a family of real valued functions defined on and expressing numerically the consequences of choosing when the state is . The set is regarded as a subset of the space of all real valued functions on endowed with the topology of pointwise convergence.As for as admissibility is concerned all the pertinent information about decisions are contained in the corresponding functionsW .This allows to introduce a notion of partial admissibility through the neigh-bourhoods of this topology. Admissibile decisions are then shown to be limits of monotone non increasing sequences of partially admissible decisions.Moreover this topological characterization allows to prove the completeness of classes of admissible decisions under acceptable systems of conditions which contain as special cases, known results in literature.

Sub additive measures of relative information and inaccuracy

Summary In the study of information theoretic measures, additivity has been the basic requirement. However it is quite interesting to investigate the sub-additive measures. Starting from subadditivity for measures associated with a pair of distributions of a discrete random variable, it has been changed into an equality relation using another function of a pair of distributions., Under the sum property of the function and the measures, the relation is expressed in terms of a functional equation of which the most general complex solutions have been obtained. In terms of the real continuous solutions of the functional equation, the sub-additive measures of Relative information and Inaccuracy have been defined and characterized. Particular cases and simple properties particularly the convexities of some of these new measures have also been studied.     

On the unimodality of passage time densities in birth-death processes

It has been shown [2] that for any ergodic birth-death process the p.d.f. of T_on , the passage time from the reflecting state 0 to any level n is log-concave and hence strongly unimodal. It is also known (cf [2]) that the p.d.f. of T_{n, n+1} or T_{n+1, n} for such a process is completely monotone and hence unimodal. It has been conjectured that the p.d.f. for the passage time T_mn between any two states is unimodal. An analytical proof of the result is presented herein, based on underlying renewal structure and methods in the complex plane. It is further shown that the p.d.f. of T_mn can always be written as the convolution of two p.d.f.s, one completely monotone and the second PF and hence log-concave.     

Veblen's Theory of Institutional Change: An Explanation of the Deregulation of Japanese Financial Markets

A bstract In his 1915 essay "The Opportunity of Japan," Thorstein Veblen theorized that traditionai Japanese institutions would undergo evolutionary change as Japan exploited borrowed industrial technology and became integrated into the global business enterprise system. This article explains the recent liberalization of Japanese financial markets which followed Japan's rise to economic prominence within the context of Veblen's theory of institutional development of the enterprise system. The Japanese process of financial deregulation is reviewed, Veblen's predictions Japan are presented and an explanation provided for the liberalization of Japanese financial markets .     

Announced layoffs: Their effect on corporate financial performance

Conventional wisdom holds that when a firm gets into trouble due to lagging sales and rising costs, cutting the size of the organization to reduce fat and waste is a normal and effective response. In this study, evidence was found to suggest that just the opposite might be true. The financial performance of Fortune 100 companies was tracked over a five-year period—two years prior to the announced layoff, the year of the layoff announcement, and two years following it. Contrary to expectations, the results indicate that financial performance worsened, rather than improved, following announced layoffs. Strategic and human resource implications for the management of corporate downsizing are provided.     

Irrelevance of the soft budget constraint for the shortage phenomenon

Kornai's thesis that shortage results from demand expansions bred by the soft budget constraint, derives from his implicit assumption that price regimes of input and output firms are different. Since any firm is both an input and an output firm, which discards the assumption as logically untenable, excess demand can only turn up because of lower than contracted inputs of labor and management that are not offset by an adequate downward adjustment of earnings. Expansions of demand that appear to be autonomous, are incited by uncertain deliveries of inputs, that is, by inefficiency (of output firms) as well. A by far the largest part of excess demand can be explained by state preferences for fast growth. As planners are more successful in generating investment, and the ensuing consumer, demand than in expanding production, shortage is inevitable regardless of the character of the firms' budget constraints.     

The effect of rule 12b-1 on bond fund expense ratios

This paper presents empirical evidence that bond mutual funds which have adopted the use of 12b-1 fees have not achieved the goal of lowering expense ratios. Using a model specific to bond funds, as opposed to generic models used in previous studies on equity funds, the analysis confirms that the 12b-1 fee is an additional cost borne by shareholders of the fund without any additional benefit. However, this cost as a percent of the net asset value of the fund has decreased from 1991 through 1994. This reduction coincides with the submission of a proposed rule change by the National Association of Security Dealers concerning maximum sales charges imposed by mutual funds on December 28, 1990 and the implementation of limits on 12b-1 fees which became effective in July of 1993.     

Profit inefficiency of Indian farms: A system approach

This article attempts to measure the level of profit inefficiency of Indian farms using a stochastic profit function. In the process, the degree of misallocation of inputs and nonoptimal supply of output is also estimated. Likelihood ratio tests allow division of total observations into two groups-large and small farms. Results indicate that both groups are profit-inefficient due to misallocation of inputs and undersupply of output. However, small farms are less profit inefficient than their larger counterparts. Within each group relatively larger farms are less inefficient.The editor for this paper was Lennart Hjalmarsson.
