We use a human-subjects experiment to investigate how bargaining outcomes are affected by changes in bargainers’ disagreement payoffs. Subjects bargain against changing opponents, with randomly drawn asymmetric disagreement outcomes that vary over plays of the game, and with complete information about disagreement payoffs and the cake size. We find that subjects only respond about half as much as theoretically predicted to changes in their own disagreement payoff and to changes in their opponent’s disagreement payoff. This effect is observed in a standard Nash demand game and a related unstructured bargaining game, in both early and late rounds, and is robust to moderate changes in stake sizes. We show theoretically that standard models of expected utility maximisation are unable to account for this under-responsiveness, even when generalised to allow for risk aversion. We also show that quantal-response equilibrium has, at best, mixed success in characterising our results. However, a simple model of other-regarding preferences can explain our main results.  相似文献

This paper looks at direct mail in the United Kingdom across all market sectors and in detail at the charity sector. It uses the research information that Royal Mail has been collecting foroveradecadetoshowthegrowthofthe medium. The diary system used by the Consumer Panel gives an insight into the typical donor and their relationship with charities. This paper looks only at direct mail: ‘personally addressed advertising material that is delivered through the post’. This definition means that leaflets put through the letterbox are excluded.

The paper discusses excess returns within four Scandinavian stock markets and also how Scandinavian returns are related to the returns in non-Scandinavian markets. Some underlying reasons for the observed economically weak relationships between markets are reviewed. Moreover, some reasons why the interrelationships between markets can be expected to increase in the future are provided.  相似文献

We present an economically motivated two–factor term structure model that generalizes existing stochastic mean term structure models. By allowing a certain parameter to acquire dynamical behavior we extend the two–factor model to obtain a nonlinear three–factor model that is shown, in a deterministic version, to be equivalent to the Lorenz system of differential equations. With reasonable parameter values the model exhibits chaotic behavior. It successfully emulates certain properties of interest rates including cyclical behavior on a business cycle time scale. Estimation and pricing issues are discussed. Standard PCA techniques used to estimate HJM type models are observed to be equivalent to dimensional estimates commonly applied to 'spatial data' in nonlinear systems analysis.
It is concluded that techniques commonly used in the analysis of nonlinear systems may be directly applicable to interest rate models, offering new insights in the development of these models. Tests of nonlinearity in interest rate behavior may need to focus on long cycle times.  相似文献

Laser scanning is a very efficient way to generate realistic, high-resolution digital models of 3-D geological outcrops. This paper discusses the methodologies involved in the creation and analysis of virtual outcrops, based on laser scanner data. The visualisation of the laser scanner data as a photorealistic 3-D object is described. Geological features picked out on the virtual outcrop (e.g. fractures, faults or bedding planes) can be extrapolated outward, into space, and inward, into the subsurface, using tension surfaces.  相似文献

This article reports findings of an experiment motivated by a dynamic labor market model that considers the problem faced by employers in making hiring decisions between workers of different types. The question examined here is how quickly employers learn about the ability of a group of workers through observing representatives of that group. If prior opinions are weak, the employer will use Information from the workplace to quickly update any incorrect group-based stereotypes it may have. On the other hand, if priors are heavily weighted, incorrect initial perceptions will result in persistent wage differences. Our experimental findings are twofold. First, subjects' (employers') behavior moves quickly toward optimal choices. Second, strong priors are hard to establish. These results suggest that it would take a long time for employers to form group-based stereotypes and that such stereotypes should go away quickly in response to signals that contradict these stereotypes.  相似文献

The Canada-US Free Trade Agreement, which came into effect on 1 January 1989, could well prove to be a breakthrough in the liberalization of trade between the two countries. This paper highlights the provisions of the FTA that indirectly or directly affect the telecommunications industry, assesses their possible impact and evaluates their probable importance to different participants in the industry. The authors make many predictions as to the effects of this agreement in terms of both telecommunications equipment and services and foresee greater competition and larger markets.  相似文献
