Unequal opportunities and human capital formation

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and aggregate efficiency in human capital formation. Using numerical solutions we study how the endogenous variables of the model respond to two different interventions in the distribution of opportunities: a mean-preserving spread and a change in the support. The results suggest that a higher degree of inequality of opportunities is associated with lower average level of human capital, a lower fraction of individuals investing in human capital, higher inequality in the distribution of human capital, and higher wage inequality. In particular, the model does not predict a trade-off between aggregate efficiency in human capital formation (as measured by the average level of human capital in the economy) and equality of opportunity.

Coalition Analysis in Group Decision Support

GMCR II, a decision support system based on the Graph Model for Conflict Resolution, now contains an algorithm for Coalition Analysis to alert users that certain decision-makers would find it both feasible and beneficial to co-ordinate their actions. The theory and implementation of Coalition Analysis in GMCR II are discussed and illustrated.     

Employment change in independent owner-managed high-technology firms in Great Britain

There is a growing volume of literature that points to the potential for small technology-based firms to achieve substantial employment growth. As a direct consequence of such work this sector of any economy has attracted increasing attention from national and local Governments concerned with finding ways of revitalising economically deprived localities and creating employment opportunities. This paper provides up-to-date empirical evidence surrounding the ability of small high-technology firms to create additional jobs in Great Britain. In addition, key founder and business characteristics are isolated which are significantly associated with employment change in growing high-technology firms over the 1986 to 1992 period. With respect to factors influencing these high levels of employment growth, a high firm size (in 1986) was found to act positively on employment growth, as was a graduate level education for the key founder. On the finance side firms which had access to and used a multiplicity of sources of start-up finance tended to grow faster. Futher, on the basis of our results we would suggest (and recommend) a Government policy which at the firm level actively encourages high-technology firm start-ups (who record higher rates of survival than firms in more conventional sectors) as well as providing support for existing high-technology firms who have already demonstrated the inclination and ability to grow in employment size.     

ON VALUING STOCHASTIC PERPETUITIES USING NEW LONG HORIZON STOCK PRICE MODELS DISTINGUISHING BOOMS,BUSTS, AND BALANCED MARKETS

For longer horizons, assuming no dividend distributions, models for discounted stock prices in balanced markets are formulated as conditional expectations of nontrivial terminal random variables defined at infinity. Observing that extant models fail to have this property, new models are proposed. The new concept of a balanced market proposed here permits a distinction between such markets and unduly optimistic or pessimistic ones. A tractable example is developed and termed the discounted variance gamma model. Calibrations to market data provide empirical support. Additionally, procedures are presented for the valuation of path dependent stochastic perpetuities. Evidence is provided for long dated equity linked claims paying coupon for time spent by equity above a lower barrier, being underpriced by extant models relative to the new discounted ones. Given the popularity of such claims, the resulting mispricing could possibly take some corrections. Furthermore for these new discounted models, implied volatility curves do not flatten out at the larger maturities.     

Methodological Issues in Negotiation Research: A State-of-the-Art-Review

This study provides insight into the dominant methodological practices that have shaped the field of negotiation over the past four decades and sheds light on possible gaps and trade-offs. We content analyzed 941 peer-reviewed negotiation articles (published between 1965 and 2004) and identified the most important methodological trends over time. The results reveal significant changes in reliability, validity, and triangulation issues. In addition, the rise of multivariate statistics and multiple data sources displays positive evolution towards more sophisticated methodologies. Despite these positive evolutions, we want to encourage current and future researchers to conduct more longitudinal and qualitative research to further advance our knowledge on negotiation.     

Mediation as an Ethical Adjunct of Stakeholder Theory

A driving force behind the evolution of the stakeholder concept is the potential of negative outcomes for an organization as the result of conflict between that organization and its stakeholders. Where conflict does arise between an organization and stakeholder how might it be resolved in a manner compatible with stakeholder theory? Applying feminist ethical theory as a theoretical basis for stakeholder theory, mediation provides an appropriate process for resolving such disputes in comparison to traditional adversarial strategies. This paper discusses the attributes of mediation, and its potential benefits as a method to resolve disputes between businesses and their stakeholders.
