Contest success functions: an extension

Summary. This note extends the axiomatic characterization of the power success function in fair contests by Skaperdas (1996) to an unfair contest. We show that the results previously obtained are straightforward to generalize; the success function is uniquely characterized by Luces Choice Axiom (implying independence of irrelevant alternatives) and homogeneity of degree zero.Received: July 1, 1996; revised version: October 30, 1996This revised version was published online in February 2005 with corrections to the cover date.     

Risk-Aversion in Constitutional Choice: Reply to Kyriacou

In his comment on my article on the possibility of discriminatory and non-consensual decsionmaking under Buchanan's veil of uncertainty (Müller 1998) Andreas Kyriacou proposes to take the players to be quasi-risk averse in order to secure fair and unanimous results at the constitutional level. As analytical tools of incorporating this premise into my model he not only suggests to assume that the individuals weigh losses higher than gains but also to take them as being rational maximiners. In this reply to his comment it is argued that both these points are inadequate to weaken my case against the veil's ability to guarantee unanimity and fairness of constitutional decisionmaking in view of a post-constitutional prisioners dilemma.     

Are firms reluctant to engage in inter-organizational exchange relationships with competitors?

Using data on the establishment of Venture Capital syndicates in Germany during the period 1995-2005 I document that relationships are formed between VCs that occupy different strategic positions in the network to allow for the combination of complimentary investment expertise.     

The Copeland rule and Condorcet’s principle

Summary. The purpose of this note is to shed some light on the relationship between the Copeland rule and the Condorcet principle in those cases where there does not exist a Condorcet winner. It will be shown that the Copeland rule ranks alternatives according to their distances to being a Condorcet winner.Received: 30 July 2003, Revised: 31 December 2003, JEL Classification Numbers: D70, D71.Christian Klamler: I am very grateful to Daniel Eckert and Nick Baigent for their helpful comments.     

Testing theoretical explanations for investment behaviour in the Dutch beam trawler fishery in the North Sea

In this study, we investigate whether the neoclassical economic theory, capital market frictions or preference-based theory can explain investment behaviour in the Dutch beam trawler fishery in the North Sea. By presenting a number of estimations, we show that vessels conducting pulse fishing invest substantially more than similar vessels undertaking conventional fishing, even after controlling for differences in such variables as capital stock, prices, profits and quotas. One possible explanation for this result is that vessel owners may obtain a separate benefit from investing in pulse fishing.     

The link between salespeople’s job satisfaction and customer satisfaction in a business-to-business context: A dyadic analysis

Although it has frequently been argued that the job satisfaction of a company’s employees is an important driver of customer satisfaction, systematic research exploring this link is scarce. The present study investigates this relationship for salespeople in a business-to-business context. The theoretical justification for a positive impact of salespeople’s job satisfaction on customer satisfaction is based on the concept of emotional contagion. The analysis is based on a dyadic data set that involves judgments provided by salespeople and their customers collected across multiple manufacturing and services industries. Results indicate the presence of a positive relationship between salespeople’s job satisfaction and customer satisfaction. Furthermore, the relationship between salespeople’s job satisfaction and customer satisfaction is found to be particularly strong in the case of high frequency of customer interaction, high intensity of customer integration into the value-creating process, and high product/service innovativeness.     

Optimal consumption and the timing of the resolution of uncertainty

As is well-known, consumers want to accumulate precautionary savings in the face of income risks when their marginal utility is convex (prudence). In this paper, we explore the effect of the timing of the resolution of income uncertainty on savings. An agent faces uncertainty about his income at date t+2. What is the effect of being informed that the uncertainty will be resolved at date t+1 on the consumption at date t? We show that the effect is positive, if and only if, marginal utility is convex (prudence), when either the risk free rate is equal to the rate of pure preference for the present, or when the utility function is HARA. The intuition is that an early resolution of uncertainty allows for time-diversifying the risk. It therefore plays a role similar to a reduction of the income risk, whose effect on savings is negative under prudence.     

Induced-Value Tests of Contingent Valuation Elicitation Mechanisms

Using an induced-value experimental design that varies whether values for a “good” are certain or uncertain and whether payment is real or hypothetical, this study investigates issues of demand revelation, hypothetical bias, and value uncertainty for four elicitation mechanisms used in contingent valuation surveys: dichotomous choice, dichotomous choice with follow-up certainty question, payment card, and multiple-bounded discrete choice. For all elicitation mechanisms, we find no evidence of hypothetical bias: voting decisions do not vary systematically when payment is hypothetical versus when it is real. Under all design conditions we find the fewest deviations between stated and induced values and the strongest evidence of demand revelation with dichotomous choice. Stated uncertainty in dichotomous choice follow-up and multiple-bounded discrete choice questions does correlate with uncertain induced values, but the signal is noisy. We discuss the implications of our findings for the design of contingent valuation surveys.     

Managing complex adaptive systems — A co-evolutionary perspective on natural resource management

The overexploitation of natural resources and the increasing number of social conflicts following from their unsustainable use point to a wide gap between the objectives of sustainability and current resource management practices. One of the reasons for the difficulties to close this gap is that for evolving complex systems like natural and socio-economic systems, sustainability cannot be a static objective. Instead sustainable development is an open evolutionary process of improving the management of social-ecological systems, through better understanding and knowledge. Therefore, natural resource management systems need to be able to deal with different temporal, spatial and social scales, nested hierarchies, irreducible uncertainty, multidimensional interactions and emergent properties. The co-evolutionary perspective outlined in this paper serves as heuristic device to map the interactions settled in the networks between the resource base, social institutions and the behaviour of individual actors. For this purpose we draw on ideas from complex adaptive systems theory, evolutionary theory and evolutionary economics. Finally, we outline a research agenda for a co-evolutionary approach for natural resource management systems.
