Large sunk investments in advertising allow managers to credibly preempt potential entrants by introducing new products prior to anticipated increases in market growth. Previous investment in advertising can lower a firm's cost to introduce new products allowing it to credibly preempt potential entrants. Entrants may not have enough residual share to find it profitable to enter later, and incumbents find it profitable to keep new products in the market even if entrants choose to enter. I present empirical evidence from the RTE cereal industry. 相似文献

I study a version of the Stackelberg game with many identical firms in which leaders and followers use a continuous cost function with no fixed cost. Using lattice theoretical methods I provide a set of conditions that guarantee that the game has an equilibrium in pure strategies. With convex costs the model shows the same properties as a quasi-competitive Cournot model. The same happens with concave costs, but only when the number of followers is small. When this number is large the leaders preempt entry. I study the comparative statics and the limit behavior of the equilibrium and I show how the main determinants of market structure interact. More competition between the leaders always displaces the followers. Instead, how a stronger threat of entry affects the equilibrium depends on the technology. With strictly convex costs it is the followers that eventually displace the leaders. 相似文献

研究目的:分析中国政府土地优先购买权实现的可行性与存在的问题。研究方法:结合中国相关管理法规与实践并与国外经验对比,对中国政府土地优先购买权的功能进行可行性分析。研究结果:中国政府的土地优先购买权在防止低价转让、储备土地来源、获得公共建设用地等方面的功能受到极大约束,主要是由于权利内涵的空洞和实施规范的缺失造成的,而深层原因是中国政府掌握着具有强制力的其他获取土地的手段。政府土地优先购买权功能在近期难以实现。研究结论:当前的政策环境使得政府土地优先购买权成为一个空制度。 相似文献

This paper extends the strategic interactions between producers of fossil fuels concerned about their profits and a taxing government concerned about the consumers’ welfare for uncertainty: global warming follows an Itô -process. Stochasticity requires to differentiate between reversible and irreversible emissions in contrast to the deterministic version. The unconstrained (= reversible) case allows for a closed form solution but not the more realistic and constrained case. Nevertheless interesting analytical properties (e.g. about when to stop emissions, implicit conservation due to monopolistic supply) are derived and complemented by a numerical example. 相似文献

We study the accounting and stock performance of 4547 US acquisitions during 1989 and 2008. We categorise acquisitions into four types based on the four possible combinations of positive or negative abnormal stock performance and abnormal accounting performance. First, we compare the bidder, bid and target characteristics across the four types of acquisitions. We find significant differences. Second, with the help of existing theories we explain these differences in bidder, bid and target characteristics by differences in the acquisition motives. 相似文献

This study uses a historical setting in which expected litigation costs were low (i.e., Australia, from 1993 to 1996) to investigate whether companies with good news were more likely to preempt annual earnings than their counterparts with bad news. Empirical tests compare the probability of preemption conditional on having good news with the probability of preemption conditional on having bad news. The models control for other potential determinants of disclosure policy that have been documented in the literature. The results do not support the research hypothesis that companies with good news were more likely to preempt annual earnings than companies with bad news. This finding suggests that there may be other factors driving disclosure of bad news, in addition to those acknowledged in the extant literature. The evidence also indicates that in Australia during the investigation period, the probability of preemption was positively associated with firm size and analyst following and differed as a function of industry membership. 相似文献

对于先买权的法律规制,在厘清先买权的成立与行使之间关系的基础上,主要从先买权的行使条件、行使时间和行使方式三个方面着手。在行使条件上,着重把握先买权行使的启动条件和实质性条件的认定;在行使时间和行使方式上,对常态和异态两种情形分别予以讨论。最后,对于先买权作为一项民法制度在未来的民法典中的应然定位做一大胆的设想和论证,以供未来民商事立法参考。 相似文献

During the past 25 years, many state governments in the United States have adopted anti-community state preemption laws to preclude local governments from enacting ordinances regulating pesticides. In the absence of local controls, people and property are being adversely effected. The issue accompanying state preemption statutes is whether the laws constitute a reasonable resolution of the positive and negative externalities that accompany pesticide usage. Through a discussion of the tradeoffs involving pesticide preemption, we show that states having divergent agricultural, residential, commercial, and recreational activities might be better served by allowing local governments to govern selected matters involving pesticides. State pesticide preemption laws denigrate local governance and compromise public health and economic well-being. If legislators care about the health of their communities and citizens, they need to repeal preemption laws that prevent appropriate safety regulations by local governments. 相似文献

共有人的优先购买权是法律赋予共有人的权利,其权利具有法定性,物权性.共有关系中优先购买权是一种待实现的权利即期待权,同时也是附条件的以自己单方意思表示就能使法律关系发生变化的形成权.权利的行使以财产共有关系存在为前提,受"同等条件"的限制.权利的实现是在共有权人内部之间,共有权人与承租人之间,共有权人与善意取得第三人之间产生. 相似文献
