Bilateral bargaining, unverifiable quality, and options to return

Summary. The paper investigates an alternating-offers bargaining game between a buyer and a seller who face several trading opportunities. These items (goods or services) differ in their non-verifiable quality characteristics which gives rise to a moral hazard problem on the seller's part. For the special case of two goods, we completely characterize the set of subgame-perfect equilibria. We find that the seller always extends an option to return the good, while the buyer may suffer from this warranty. Also, qualitatively different types of equilibrium outcomes occur depending on the parameters of the model: (a) the seller may obtain a larger share of the surplus although the parties ex ante have symmetric bargaining positions, (b) the subgame-perfect equilibrium may entail inefficient trade, and (c) multiple equilibria may exist including equilibria with delay in negotiations. Finally, we analyze a situation where bargaining proceeds after the good was returned which is shown to reestablish uniqueness and efficiency of equilibrium.Received: 23 August 2001, Revised: 3 April 2003, JEL Classification Numbers: C78, L14, L15, D82.

Effort, trade, and unemployment

Abstract.  This paper incorporates equilibrium unemployment caused by efficiency wages into a monopolistic competition model of trade. Worker effort is treated as an endogenous variable that depends on the optimizing behaviour of firms and workers. Opening up trade induces firms to demand greater worker effort and to cut the size of their workforce. This counteracts the positive employment effect due to entry of firms. Circumstances are indicated in which the two effects just balance, leaving aggregate employment unchanged. Trade unambiguously increases worker effort, thereby enhancing within-firm productivity.     

Environmentalism—A Question of Guilt? Testing a Model of Guilt Arousal and Effects for Environmental Campaigns

Guilt has been identified as a crucial factor mediating the effects of social campaigns. So far, however, knowledge regarding the process of guilt arousal is limited. This paper studies processes of guilt arousal and effects for the context of environmental donation campaigns. Following the extended parallel process model, environmental concern and self-efficacy are introduced as main predictors. Results of an experiment show that guilt arousal enhances campaign effects for those with a high concern but is the wrong strategy to reach those with a low concern. Guilt arousal is not influenced by self-efficacy and occurs independently of emotional message frames.     

Neue Anforderungen an optimierende Energiesystemmodelle für die Kraftwerkseinsatz- und Zubauplanung bei begrenzten Netzkapazitäten

Recent changes in energy economic frameworks conditions lead to new requirements for energy systems models. Particularly in Germany, structural and locational changes in the power plant sector can be observed. Above all, this is due to the liberalisation process entailing the legal unbundling of system operators and generation companies as well as to the ambitious aims for the extension of wind energy. Consequently, modelling energy systems as single node systems, in which network constraints are neglected, can lead to suboptimal results. Most energy systems models offer the possibility to limit interregional energy exchange capacities. However, these so-called transhipment models normally neglect the actual load flows. Yet, there are several possibilities to adequately consider the characteristics of power transmission. In this paper, the most popular approaches, which are used in particular technical applications, such as the AC- (Alternating Current), the DC- (Direct Current) and the PTDF- (Power Transfer Distribution Factors) approach are introduced and discussed with respect to their application in energy systems models. In addition, first experiences with their implementations are presented.     

The European Monetary Union break-up: an economic experiment on the return of the deutsche mark

By using the macro-econometric input–output model INFORGE, this paper investigates the economic effects of a unilateral break-up of Germany from the European Monetary Union (EMU). The results show that a return to a national currency lowers Germany's growth path. Positive effects of a break-up due to lower domestic prices, increasing real wages and lower imports are fully compensated by the loss in international competitiveness. On industrial level, the negative implications are the strongest in those industries that depend strongly on exports. Strong indirect implications are expected for the business-related service sector. Although the results of this economic experiment depend strongly on its underlying assumptions, it can be shown that a break-up of the EMU would result in a heavy welfare loss for Germany.
