A modified logit model for time series with an application to the pricing behaviour of manufacturing firms in Australia

The modified logit model (Amemiya and Nold, 1975) is generalised to the case where the error term is autocorrelated. The asymptotic distribution (as n →∞ and T →∞) of a feasible GLS estimator of β is derived. Tests of linear restrictions on β and the significance of ρ are presented. The results of the applied work suggest that the factors which explain the pricing behaviour of manufacturing firms, as reported in the tendency survey conducted by the Australian Chamber of Commerce and Industry and the Westpac Banking Corporation, include historical inflation rates of up to 7 quarters and capacity utilisation.

基于随机动态规划法的IT项目经济评价

传统的项目经济评价方法--TOC和ROI法不能有效地分析IT项目的投资价值,还可能导致错误的投资决策.通过引入随机动态规划法,可导出两类IT项目(购置型项目和自主开发项目)的经济评价模型,给出项目的投资决策临界值解,并进行详细的影响因素敏感性分析.该评价模型放松了金融期权定价模型的假设前提,更符合IT项目的实际情况,从而能准确地评估IT项目中内含的期权价值和投资机会价值.     

高新技术产业化中风险投资问题的实物期权分析

高新技术产业由于具有投资的不可逆性和很大的收益不确定性,因此不能采用传统的净现值方法来评估是否对其投资。本论文在分析高新技术产业特点的基础上,提出了嵌入期权的现金流量图评估方法,并且根据经验法则求出了风险投资公司应占高新技术企业的股份。     

分数布朗运动环境下的美式看涨期权的定价方法

在分数布朗运动模拟算法基础上,提出了分数布朗运动环境下标的资产价格过程的一种数值模拟方法。然后应用于欧式和美式看涨期权定价。结果表明,该方法具有很快的收敛速度,而且基于最小二乘方法和偏最小二乘方法的美式看涨期权价格,都与对应的欧式看涨期权价格几乎完全一样。这恰恰验证了不支付红利的条件下,美式看涨期权不应该提前执行的理论论断。     

我国上市公司融资决策归因分析

在现有融资决策理论的基础上,利用现金流股价模型及实物期权方法,来量化上市公司融资决策中的确定性成本和不确定性因素,并对我国上市公司的融资决策进行归因分析。研究表明,融资成本不是企业融资决策的决定性因素,不同融资方式的期权价值对融资决策有重要影响。公司采取何种融资策略,要比较股权融资成本+股权融资期权价值和债权融资成本+债权融资期权价值的大小,上市公司的经营状况与债权融资存在正相关关系。本文扩展了融资决策的动因分析,为定量评价融资行为提供了依据。     

基于投资者异质性信念的证券定价模型——对我国股票市场价格的实证检验

投资者异质性信念的相互作用影响着证券价格，证券市场上的各种证券需求与供给关系,往往表现为投资者各种不同信念的对抗和交融。本文以悲观信念（看多）和乐观信念（看空）之间的相互作用为例，研究了异质性信念对资产均衡定价的影响，并以我国股票市场的机构投资者信念为对象进行了实证检验，得出我国股票市场投资者信念与证券价格相互作用的结论。本文的建议是在投资过程中，准确分析市场中投资者的异质性信念结构，尤其是资金雄厚的机构投资者的信念结构至关重要。     

The micro-foundations of intertemporal price discrimination

Summary. This paper investigates the optimality of intertemporal price discrimination for a durable-good monopoly in a model where infinitely-lived households face an intertemporal budget constraint, and consume both durable goods and non-durable goods. We prove that the optimal price of the durable good is not constant, and may decrease or increase over time. Some households may choose to purchase the durable good at a later date, and pay lower or higher prices, since the gain in discounted utility of consuming more of the non-durable good more than compensates for the loss in utility from delaying the consumption of the durable good.Received: 12 March 2004, Revised: 7 January 2005, JEL Classification Numbers: D40, D42, D91.I would like to thank C.D.

Pricing access in network competition

We compare various access pricing rules in the two-way access model. We show that the Generalized Efficient Component Pricing Rule (TECPR) leads to a lower equilibrium price than does the Efficient Component Pricing Rule, (ECPR) marginal cost pricing, (MCP) and any non-negative fixed access charges.
