Summary. An economy with two dates is considered, one state at the first date and a finite number of states at the last date. Shareholders determine production plans by voting - one share, one vote - and at
-majority stable stock market equilibria, alternative production plans are supported by at most
percent of the shareholders. It is shown that a
-majority stable stock market equilibrium exists if
where S is the number of states at the last date and J is the number of firms. Moreover, an example shows that
-majority stable stock market equilibria need not exist for smaller

The objective of this paper is to present econometric evidence of the effects of economic incentives, public policies, and institutions on national aggregate private agricultural R&D investments. The main hypothesis we will test in this paper is whether agricultural R&D spillovers represent a disincentive for national private R&D. More specifically, we will test if the spillovers function, which is a determinant of private R&D, follows a quadratic form and if private R&D is determined by the role of incentives and institutions.A previous draft of this paper was presented at the 57th International Atlantic Economic Conference, Lisbon, Portugal, 10–14 March 2004. Comments from participants have been very useful to improve the paper. 相似文献

研究中习惯用回报/盈余关系来表示会计盈余的信息含量。通过A股的实证结果发现,当时间窗口为公告日前后60关时,回报/盈余关系较显著;盈余的持续性越高,回报/盈余关系越显著;非线性的模型比线性模型的解释能力更强。但是模型总体的R2水平都较低,这可能是由于研究方法的缺陷、市场的非理性、盈余本身信息含量低等原因造成的。 相似文献

We consider the M/M/1-queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the result. 相似文献

我国M_2/GDP的动态增长路径、货币供应量与政策选择 总被引:22,自引:2,他引:22
本文试图求解我国M2/GDP的动态增长路径,并对与此相关的金融政策选择进行分析。研究发现,我国M2/GDP的变动路径具有Logistic曲线的基本形状,将经历先加速上升后增长速度逐渐减缓,最终趋于稳定状态的变化过程。本文估算了我国M2/GDP的增长上限及其变化拐点。研究还发现,M2/GDP的上升并不必然意味着通胀压力加大,只有M2/GDP偏离动态增长路径时,才会对通货膨胀产生影响。据此本文估算了2005年货币供应量的合理区间。本文认为,应继续实施稳健货币政策,合理确定货币总量增长速度,继续推进体制性改革等措施确保经济金融的稳定运行。 相似文献

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares. 相似文献

The simultaneous management, in an international context, of free-access renewable resources and transboundary pollution, is examined in a dynamic game framework. First-best outcomes under international cooperation are determined and compared to noncooperative outcomes when countries follow linear Markov strategies. An international policy consisting of taxes on emissions and harvesting, with international redistribution of tax receipts, is used to achieve the cooperative solution. In addition, side payments may be required to prevent free riding and thus make the international policy implementable.Earlier versions of this paper were presented at the International WorkshopEconomic Aspects of International Water Resources Utilization in the Mediterranean Basin, Fondazione ENI Enrico Mattei, Milan, October 1993, and the Fifth Annual Conference of EAERE, Dublin, June 1994.
