Although pension funds have gained importance in the last two decades, their role has not been described in detail by economic models. This article focuses on the scope of these institutional investors when they are not satisfied with a management team of a company in which the pension fund holds a block of shares. Stock holdings by pension funds are largely dispersed. Therefore, any intervention by pension funds in corporate governance requires the formation of a coalition of pension funds. The realization of a coordinated intervention, in turn, is subject to the problems related to the provision of public goods, such as free riding. We find that the stock dispersion and the combined share of pension funds, coordination costs and the attractiveness of the exit option are relevant factors for determining the probability of the success of interventions. 相似文献

This paper considers an acid rain differential game. Countries emit sulphur which is partly transferred to other countries. Depositions above critical loads ultimately destroy the soil. Countries face a trade-off between the costs of emission reductions and the damage to the soil due to the depletion of the acid buffers. Because of the transboundary externalities the outcome will depend on whether the countries cooperate or not. This paper presents the cooperative outcome and the open-loop and Markov-perfect Nash equilibria of the acid rain differential game. It will be shown that the depositions always converge to the critical loads but the steady-state levels of the buffer stocks differ. The theory is used to analyse the acid rain differential game for sulphur between Great Britain and Ireland. Finally, some results are given for the whole of Europe. 相似文献

The main question of this paper is whether consistent government voters have — ceteris paribus — a more positive perception of the general economic situation than do opposition voters. First, some empirical evidence is presented which is usually thought to support this hypothesis. Next, a theoretical model is presented which shows that this evidence is not conclusive and how this hypothesis can be tested correctly. Empirical evidence for the Federal Republic of Germany, 1972–1982, shows that government voters generally had a more positive perception during this period than did traditional opposition voters, but this evidence is far from being overwhelming. 相似文献

This paper analyzes the multiple bounded format, in which uncertainty is directly incorporated into the WTP question. A new approach for analyzing multiple bounded uncertainty data is presented. The intuition underlying the approach is that uncertain individuals would like to state their WTP as intervals rather than precise values and that the width of the intervals is determined by the degree of uncertainty. The approach is compared to the one applied in Welsh and Poe [Welsh, M., Poe, G.L., 1998. Elicitation effects in contingent valuation: comparisons to a multiple bounded discrete choice approach. Journal of Environmental Economics and Management 36, 170–185] which treats uncertainty by conditioning responses on specific verbal probability statements. We argue that the conditioning approach overestimates mean and median WTP and that conditioning WTP estimates on probability statements like “probably” and “unsure” make them “fuzzy”. To empirically compare the two approaches we use data from 2004 concerning implementation of a predator protection policy in Sweden. Our analysis show that the suggested approach: (1) is more intuitive; (2) better fits the data; (3) estimates mean and median WTP with better precision; (4) is less sensitive to distributional assumptions; and (5) it is better suited for policy analysis. 相似文献

Understanding tourists' use of public transport (PT) at the destination is important for sustainable mobility, destination satisfaction, PT management and destination management. This paper provides an overview of research in PT and tourism since 2000. The review identifies main topics and issues including how PT is used for tourism purposes in different contexts. It also recommends policies and strategies for a modal shift to PT in tourism, and identifies potential areas for future research. The review indicates that there are differences in the level of PT use by visitors between rural and urban destinations. PT is often not favoured by visitors in remote areas, although the situation is more promising in urban destinations. However, the overall potential of PT as an alternative mode for travelling is unclear, given tourist motivations and behaviours, and provision of visitor-oriented PT services including the need for appropriate communication and social marketing strategies. 相似文献
