Non‐Homothetic Multisector Growth Models

Multisector growth (MSG) models are dynamic versions of computable general equilibrium (CGE) models. Non‐homothetic preference (utility) functions are required for the evolution of factor allocations and industrial structures in accordance with consumption expenditure patterns implied by the non‐unitary income elasticities observed in all budget data since Engel in the 1850s. But comparative static general equilibrium solutions and particularly solving the dynamics of MSG models require explicit specifications of all demand and cost (price) functions. On the demand side, the constant differences of elasticity of substitution (CDES) non‐homothetic indirect utility functions and Roy's identity provide the explicit Marshallian demand functions and budget shares. Sectorial constant elasticity of substitution (CES) cost functions and Shephard's lemma provide the explicit relative commodity price functions and the sectorial cost shares and capital–labor ratios. Walrasian equilibria are given by one equation and the multisector dynamics by three differential equations. Benchmark solutions are given for three cost regimes of a 10‐sector MSG model. History patterns of industrial/allocational evolutions are recognized.     

Alienation in corporate America: Fact or fable?

Using NORC annual survey data, the authors selected 21 questions describing respondent attitudes toward job, life in general, and financial status. Respondents were catigorized as management, white collar, blue collar, and those not affiliated with business organizations. Attitudes were compared across the four occupational groups. Little dissatisfaction was found in any but the blue collar group. Management as a group, and men as well as women managers showed high levels of satisfaction, with few significant differences found in responses by men and women. This study does not support the earlier finding of widespread alienation in business firms.Charles B. Sannders is Professor of Business Administration at the University of Connecticut. He has written numerous articles which have been published in various management journals.Hugh M. O'Neill and Oscar W. Jensen are Assistant Professors of Business Administration at the University of Connecticut and the Fairfield University, respectively. Both have written several articles, published in management journals.     

Reforming Social Security in a Transition Economy: The Case of Lithuania

This paper points out a number of problems associated with the existing pension system in Lithuania. Reforms are proposed, including (i) a substantial increase in the basic pension benefit rate, financed on a pay-as-you-go basis, provided universally, and regulated according to wage/price indexation; (ii) a significant cut in the tax contribution rate to the public pension system matched by a rise in the VAT; (iii) a rise in the retirement age to 65 for both men and women; and (iv) a gradual conversion to a private, funded, mandatory pension system to replace the earnings-related part of the current pension system.     

Review Essay

Sen's capability approach has a culturally specific side, with capabilities influenced by social structures and institutions. Although Sen acknowledges this, he expresses his theory in individualistic terms and makes little allowance for culture or social structure. The present paper draws from recent social theory to discuss how the capability approach could be developed to give an explicit treatment of cultural and structural matters. Capabilities depend not only on entitlements but on institutional roles and personal relations: these can be represented openly if capabilities are disaggregated into individual, social and structural capacities. The three layers interact, and a full analysis of capabilities should consider them all. A stratified method implies that raising entitlements will not on its own be enough to enhance capabilities and that cultural and structural changes will be needed.     

Strategic Intrafirm Innovation Adoption and Diffusion

A theory of oligopolistic innovation adoption is developed in which intrafirm diffusions occur because the marginal cost of adoption is increasing in the rate of adoption. The equilibrium intrafirm diffusion curve is S-shaped or concave, as are empirically observed ones. This diffusion curve is more likely to be S-shaped the more competitive the industry, the larger the marginal cost of adoption or the pre-innovation unit cost of production, or the smaller the demand. The diffusion is longer, and so the extent of adoption at any date is lower the more competitive the industry, the larger the marginal cost of adoption or the pre-innovation unit cost of production, or the smaller the demand. A surprising result is that an increase in the unit cost reduction from the innovation has an ambiguous effect on diffusion. Obviously, a larger cost reduction allows each firm to earn a larger flow profit at every date from the same rate of adoption. However, a more subtle effect is that it also allows the firm to earn the same flow of profit with a slower rate of adoption, and so lower adoption costs. That is, the firms also have an incentive to spread out the diffusion over a longer period of time to save on adoption costs.     

Agency Costs of Overvalued Equity

I define and analyze the agency costs of overvalued equity. They explain the dramatic increase in corporate scandals and value destruction in the last five years; costs that have totaled hundreds of billions of dollars. When a firm's equity becomes substantially overvalued it sets in motion a set of organizational forces that are extremely difficult to manage—forces that almost inevitably lead to destruction of part or all of the core value of the firm. WorldCom, Enron, Nortel, and eToys are only a few examples of what can happen when these forces go unmanaged. Because we currently have no simple solutions to the agency costs of overvalued equity this is a promising area for future research.     

The European economy at the cross roads: Structural reforms, fiscal constraints, and the Lisbon Agenda

This paper studies the incentives to sustain and extend a monetary union under alternative assumptions about the extent of market reform within the union and accession countries. Lack of labour mobility, or wage/price flexibility, or fiscal reform, brings costs for both new entrants and in the existing union. Countries will therefore want a union where there has been sufficient reform, and also one where markets are more flexible than their own. But existing members will want the same properties of their partners. Fiscal restrictions may exaggerate this incentive mismatch and could therefore delay the necessary reforms. Similarly, too large costs up front may also delay those reforms.     

Action-oriented approaches to technology assessment and working life in scandinavia

Several approaches to action-oriented technology assessment of aspects of working life have been tried out in Scandinavia over the past 15-20 years. This article gives an overview of the experiences in Scandinavia, with emphasis on a Danish point of view. Five different approaches to action-oriented technology assessment are described, based on an analysis of the social actors involved, the target groups for the technology assessment and the associated social mechanisms. These techniques follow the collective resource approach, the cooperative strategies, expert strategies and alternative technology, legal reform strategies and governmental technology promotion policy. None of the approaches proved to be totally effective on its own. The conclusion is that a new combination of approaches to action-oriented technology assessment and the development of a theoretical basis are needed.
