In the last few years bipartisan support for legalizing drugs has grown to a surprising level. Because of the lack of involvement of the business community in this debate, we surveyed the human resource managers of 127 firms about their perceptions of the effects of legalization. Their responses were uniformly negative, with expectations that drug use, absenteeism, worksite crime, and liability costs would increase, while the quality and quantity of work would decline. They also forecast increases in drug testing, performance monitoring, and education and rehabilitation programs as a result. 相似文献

Competing theories on internal orientation versus external orientation are examined. The relevant theories are amalgamated
and condensed into a number of competing propositions that are empirically tested. The findings suggest that the internally
oriented businesses as well as the externally oriented businesses underperform the efficient, marketing oriented businesses. 相似文献

Large Bayesian VARs with stochastic volatility are increasingly used in empirical macroeconomics. The key to making these highly parameterized VARs useful is the use of shrinkage priors. We develop a family of priors that captures the best features of two prominent classes of shrinkage priors: adaptive hierarchical priors and Minnesota priors. Like adaptive hierarchical priors, these new priors ensure that only ‘small’ coefficients are strongly shrunk to zero, while ‘large’ coefficients remain intact. At the same time, these new priors can also incorporate many useful features of the Minnesota priors such as cross-variable shrinkage and shrinking coefficients on higher lags more aggressively. We introduce a fast posterior sampler to estimate BVARs with this family of priors—for a BVAR with 25 variables and 4 lags, obtaining 10,000 posterior draws takes about 3 min on a standard desktop computer. In a forecasting exercise, we show that these new priors outperform both adaptive hierarchical priors and Minnesota priors. 相似文献

We develop a model of competition between shopping centers, comparing competitive outcomes in three alternative modes of retail organization, namely: streets (in which neither developers or retailers internalize agglomeration effects between products); malls (in which developers internalize); and supermarkets (in which both developers and retailers internalize). For a fixed number of centers: (i) converting streets to malls intensifies developer (but not retailer) competition, which increases product range (i.e., the number of shops built by the developers) and consumer surplus, reduces profits, and has ambiguous effects on welfare; (ii) converting streets to supermarkets intensifies retailer and developer competition, has ambiguous effects on product range (number of shops), reduces profits, and increases social welfare. With free entry both conversions reduce the number of centers and, if there is excess entry, conversion to supermarkets (but not malls) unambiguously increases welfare. 相似文献

This paper uses a modification of the continuous time asset pricing model of Cox, Ingersoll, and Ross to analyze the effect of regulatory risk on the cost of capital. Analysis shows that random errors in setting the allowed rate of return can either increase or decrease the cost of capital depending on other regulatory parameters. However, the analysis suggests that regulatory risk is not material. 相似文献

This article identifies key features of the strategy concept as a basis for reviewing existing theories of strategy. It also provides an agenda for future research. the article argues that there is a decision hierarchy in a firm, and defines strategy as the highest-level decision in the hierarchy. Consequently, strategy has to exhibit what may be called three features of dominance: vertical dominance, horizontal dominance, and dynamic dominance. A vertically dominant strategy is one that determines, directly or indirectly, other decisions of a firm. A horizontally dominant strategy seeks to optimize the value of the firm according to some criteria. Dynamic dominance implies that strategy should affect the subsequent decisions of a firm over a relevant period of time. With few exceptions, existing theories of strategy are issue-oriented and focus largely on horizontal dominance. More research should, therefore, be directed towards vertical and dynamic dominance criteria. If a comprehensive theory of strategy which satisfies the three dominance features cannot be developed, it is suggested that development should be directed towards integrating behavioural and economic approaches. 相似文献

The article addresses the question of whether responsibility for pollution created in the past should be retroactively applied to firms, or if the costs of cleaning up existing pollution should be financed by the public. We show that making firms liable for retrospective environmental costs can weaken the incentive to take precautions against future environmental costs. This follows since public financing of these costs can lead to greater prospective risk deterrence by allowing firms to more fully internalize the costs of future environmental risks. However, an analysis of existing public financing approaches highlights a set of dangers associated with their practical use. 相似文献

Drama theory and its relation to game theory. Part 2: Formal model of the resolution process 总被引:2,自引:0,他引:2
Nigel Howard 《Group Decision and Negotiation》1994,3(2):207-235
In a drama, characters' preferences and options change under the pressure of pre-play negotiations. Thus they undergo change and development. A formal model of dramatic transformation is presented that shows how the core of a drama is transformed by the interaction among the characters into a strict, strong equilibrium to which they all aspire. The process is seen to be driven by actors' reactions to various paradoxes of rationality. 相似文献

Drama theory and its relation to game theory. Part 1: Dramatic resolution vs. Rational solution 总被引:1,自引:0,他引:1
Nigel Howard 《Group Decision and Negotiation》1994,3(2):187-206
Drama theory differs from game theory in that it does not regard actors' preferences and perceived opportunities as fixed, but as capable of being changed by the actors themselves under the pressure of pre-play negotiations. Thus characters in a drama undergo change and development. A manyperson, multiphase theory of dramatic transformation is presented, showing how thecore of a drama (in the sense of game theory) is transformed by the interaction between the characters into a strict, strong equilibrium to which they all aspire. The process of dramatic transformation is shown to be driven by actors' reactions to various paradoxes of rationality; it is proved that when all these paradoxes have been overcome, a full dramatic resolution has been reached, satisfying actors' emotional and moral demands, as well as the demands of rationality. 相似文献
