Additive and Multiplicative Uncertainty Revisited: What Explains the Contrasting Biases?

above the certainty level while for additive uncertainty the price should be lower than the certainty level. This note gives an intuitive explanation for the result after first presenting a parsimonious review of the two models. We also discuss which, if either, of the two models is more realistic.

Ill-behaviour of transformation-frontiers with environmental quality versus pollution

If one looks at environmental quality N as a renewable natural resource (with its own natural dynamics) which is changed by emissions Z, then one gets a better understanding of the shape of the damage function. In the case of a logistic growth dynamics one obtains a well-shaped transformation frontier N(Z), even in a two-species natural dynamics. For a more general natural interaction in the framework of a prey-predator model one obtains the possibilities of a cusp catastrophe which makes the transformation frontier N(Z) ill-shaped for the standard arguments of economists and their most favoured environmental policy instruments.     

Ethical Outsourcing in UK Financial Services: Employee Rights

Outsourcing is becoming a major option in British business, including the financial services industry, and it raises a number of ethical considerations. The author of this major ethical study contends that "Outsourcing seems to present a particular threat to employees ... because of the factors which have led to outsourcing and the way in which it tends to work."

Open-bank assistance transactions and prompt corrective action

Open-bank assistance (OBA), provided to troubled banking institutions by the FDIC to prevent their failure, has been criticized extensively on grounds that closed-bank transactions, especially early closed bank transactions, are less expensive to the FDIC. This article analyzes a case in which OBA makes public policy sense, under conditions in which uncertainty is introduced into the valuation of a bank's nonperforming assets. Under such uncertainty, the FDIC may play a role by providing to the acquiror of the troubled institution essentially costless (to the FDIC) standby insurance on the ultimate workout values of the nonperforming assets. If properly structured, such an OBA transaction would meet critics' objections by minimizing FDIC cost and creating incentives for the early recapilization of troubled banks.     

Should we let employees contract away their rights against arbitrary discharge?

This article argues that the moral right to be discharged only for good cause and like rights can be contracted away by employees in appropriate circumstances. It maintains that the rights in question are not inalienable, and that there is nothing irrational about an employee's wishing to deal them away. It also maintains that inequalities in bargaining power between employers and employees are insufficiently pervasive to justify a flat ban on the alienation of these rights. For a waiver of such rights to be valid, however, employees must have full knowledge of its terms.The question addressed here bears on several legal and policy issues affecting termination of the employment relation. If employees can contract away their right to a goodcause discharge, the American doctrine of employment at willmight find justification in the face of that right. In addition, the alienability of such discharge rights may be necessary to justify express disclaimers of wrongful discharge liability and the waiver provision of the new U.S. Draft Uniform Employment-Termination Act.Michael J.

Price Competition When Consumersare Uncertain About Which Firm Sells Which Quality

In this paper we analyze the properties of price equilibria in a duopoly market where firms sell vertically differentiated products, consumers being uncertain about which firm sells which quality. Both existence and properties of price equilibria are characterized by the beliefs of the consumers' population about the distribution of quality between firms.     

The Cultural Economy of Cities

An increasingly important fraction of contemporary economic activity is devoted to the production of cultural outputs, i.e. goods and services with high levels of aesthetic or semiotic content. This kind of economic activity is especially, and increasingly, associated with a number of large cities scattered over the globe. A conceptual account of this phenomenon is provided on the basis of an exploration of the character of place-specific forms of culture generation and the agglomerative tendencies of many kinds of cultural products industries. The empirical cases of Los Angeles and Paris are briefly discussed. The dynamics of production, distribution and location of major cultural products industries are also examined. The paper ends with a brief allusion to the modalities of spatial differentiation of culture in contemporary capitalism and to a prospective cultural politics.
