在一类非线性需求函数的条件下,基于完全信息动态博弈模型,对两寡头厂商在竞争状态下同时实施二度与三度价格歧视的定价方法进行了研究,讨论了两厂商在面对两个子市场情形下,分别对各子市场的需求区间进行两段分段时的利润最大化问题,得出了在二三度价格歧视下两厂商的均衡产量与分段点,为寡头厂商的生产决策提供了理论依据.  相似文献

本对线性需求市场下三级价格歧视对总福利的影响效应进行了研究。结果显示:价格歧视对总福利的影响方向是不确定的。当没有市场排除时,价格歧视降低总福利;当发生市场排除且只供应第一个市场时,价格歧视增加总福利;若供应的市场数超过1个,则当排除市场总的潜在经济规模大于供应市场潜在规模分布的离散程度时,价格歧视增进总福利,反之,价格歧视降低总福利。  相似文献

信息产品在非线性效用函数下的二度价格歧视研究   总被引:4,自引:0,他引:4  
本中假定消费的效用函数为非线性的效用函数,垄断厂商提供同一种信息产品的两种质量版本,消费根据两类约束做出自己的消费选择。厂商通过消费的两个无差异点来对消费进行二度价格歧视,通过分析我们得出厂商的歧视条件。  相似文献

中国民航机票折扣定价策略研究   总被引:1,自引:0,他引:1  
在分析中国民航票价演变的基础上,研究了垄断航空公司折扣票价的利润最大化问题,对比分析了在单一价格、外生型价格歧视和内生型价格歧视三种情形下,折扣率对利润、价格和产出的影响,研究表明:内生型价格歧视的利润和产出大于外生型价格歧视下的利润和产出,而价格歧视下的利润大于单一价格下的利润,折扣票价的有效实施应以分隔各子市场为前提。进一步的研究应扩展到多级票价和动态定价中去。  相似文献

对两寡头厂商2元市场用完全信息动态博弈的方法分析了实施三度价格歧视情形和统一定价情形的均衡产量,均衡价格和均衡总收益,并研究了这两种情形三个指标之间的关系.结果显示,在两个子市场的需求函数为线性需求的条件下,统一定价的市场均衡产量等于歧视定价的市场均衡产量;统一定价的均衡价格是歧视定价时两个子市场均衡价格的加权平均;统一定价的市场均衡总收益小于歧视定价的市场均衡总收益.  相似文献

We study a class of self-similar processes with stationary increments belonging to higher order Wiener chaoses which are similar to Hermite processes. We obtain an almost sure wavelet-like expansion of these processes. This allows us to compute the pointwise and local Hölder regularity of sample paths and to analyse their behaviour at infinity. We also provide some results on the Hausdorff dimension of the range and graphs of multidimensional anisotropic self-similar processes with stationary increments defined by multiple Wiener–Itô integrals.  相似文献

It is considered the class of Riemann surfaces with dimT1 = 0, where T1 is a subclass of exact harmonic forms which is one of the factors in the orthogonal decomposition of the spaceΩH of harmonic forms of the surface, namely The surfaces in the class OHD and the class of planar surfaces satisfy dimT1 = 0. A.Pfluger posed the question whether there might exist other surfaces outside those two classes. Here it is shown that in the case of finite genus g, we should look for a surface S with dimT1 = 0 among the surfaces of the form Sg\K , where Sg is a closed surface of genus g and K a compact set of positive harmonic measure with perfect components and very irregular boundary.  相似文献

As early as in 1990, Professor Sun Yongsheng, suggested his students at Beijing Normal University to consider research problems on the unit sphere. Under his guidance and encouragement his students started the research on spherical harmonic analysis and approximation. In this paper, we incompletely introduce the main achievements in this area obtained by our group and relative researchers during recent 5 years (2001-2005). The main topics are: convergence of Cesaro summability, a.e. and strong summability of Fourier-Laplace series; smoothness and K-functionals; Kolmogorov and linear widths.  相似文献

Schr(o)dinger operator is a central subject in the mathematical study of quantum mechanics.Consider the Schrodinger operator H = -△ V on R, where △ = d2/dx2 and the potential function V is real valued. In Fourier analysis, it is well-known that a square integrable function admits an expansion with exponentials as eigenfunctions of -△. A natural conjecture is that an L2 function admits a similar expansion in terms of "eigenfunctions" of H, a perturbation of the Laplacian (see [7], Ch. Ⅺ and the notes), under certain condition on V.  相似文献
