We introduce bids in a rent-seeking contest. Players compete for a prize. Apart from exerting lobbying efforts, they also submit a bid which is payable only if they win the prize. We show that our model has a unique Nash equilibrium in pure strategies, in which each active player submits the same bid, while the sum of all efforts equals that bid. In equilibrium there is underdissipation of rent. 相似文献

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm. 相似文献

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population. 相似文献

According to the essential features of urban economic strips, this paper is intended to point out that Chengdu-Chongqing strip has so far been an urban area in geographic or spatial sense, but not an urban economic strip in economic sense. On further basis of analyzing several problems existing in the developrnent of Chengdu-Chongqing economic strip, some countermeasures are correspondingly put forward hereafter. 相似文献

In this paper the stability of an International Environmental Agreement (IEA) among N identical countries that emit a pollutant are studied using a two-stage game. In the first stage each country decides noncooperatively whether or not to join an IEA, and in the second stage signatories jointly against nonsignatories determine their emissions in a dynamic setting defined in continuous time. A numerical simulation shows that a bilateral coalition is the unique self-enforcing IEA independently of the gains coming from cooperation and the kind of strategies played by the agents (open-loop or feedback strategies). We have also studied the effects of a minimum participation clause finding that for this case a self-enforcing IEA just consists of the number of countries established in the clause.JEL Classification:

长江中游是长江自然—经济—社会复合生态系统的重要组成部分,当前洪涝灾害频繁而严重。按照长江洪水发生的自然规律调整好人与自然的关系,改变长期以来舍南保北、以堵为主、重蓄轻泄的做法,实施疏泄为主的防洪策略,并采取相应的工程和非工程措施(如下荆江裁弯、开辟分流洪道、四口建闸、洞庭湖水系南北分流、疏浚河道、南水北调及平垸行洪等),同时配合进行水源生态工程及江河库湖调蓄工程建设,才能根治长江中游洪涝灾害。 相似文献
