城镇土地估价的相关技术标准分析--<城镇土地估价规程>与<房地产估价规范>比较 总被引:1,自引:0,他引:1
研究目的比较分析<城镇土地估价规程>与<房地产估价规范>在技术标准上的差异性,确定未来城镇土地估价的技术规范方向.研究方法文献资料法和比较分析法.研究结果(1)两个技术标准都强调价格的正常性,但土地估价更多从权益角度考虑,突出出让土地使用权的地位,房地产估价更多地从正常市场交易的价格前提考虑,从而导致估价基础的差异;(2)二者估价的方法相近,但术语用词、应用要求存在差别,特别是基准地价的制定和应用在土地估价中有着重要的地位;(3)对土地权益和与之相关的估价目的,土地估价重视不同用途和各种权利状况下的估价操作,房地产估价则重视具体目的估价时对合法原则的遵循.研究结论两个技术标准应逐步统一,以适应规范市场的发展需要,其关键在于明确基准地价在中国估价技术中的重要地位;规范统一专业术语;统一估价目的方法应用要求。 相似文献

Marketing practitioners have recognized a growing need to measure consumer-generated social media in a standard way since there are numerous social media indicators in use, making intra- and inter-company comparisons difficult. This paper identifies four social media dimensions for measurement and evaluation: technological, social, economic, and ethical; and, subsequently, measures social media. The study makes a contribution to social media literature by using analytic hierarchy process of developing a mathematical model for social media index valuation. The “social media composite index number” will serve as an industry benchmark signifying the organization's share and commitment to social media. 相似文献

Deciding on advertising appropriations is a common problem to all National Tourist Offices. The Austrian National Tourist Office now employs a decision support model allowing for inclusion of managerial judgments. In tourism, like elsewhere, application of standard optimization routines to marketing decision making is straight- forward, once the relationship linking market response to input has been modeled adequately. A tailor-made decision calculus procedure eliciting managerial judgments on the relative importance of the factors determining a receiving country's travel market share provides the weights otherwise inaccessible by objective parameter estimation. A tourism manager thus can evaluate countries as tourism generators and allocate an advertising budget accordingly. 相似文献

Abstract. In addition to standard methods of environmental valuation, a novel approach has recently emerged which models individuals' self-rated happiness as a function of their incomes and the prevailing environmental conditions. The estimated relationship is used to calculate the trade-off people would be willing to make between income and environmental conditions, i.e. the increase in income necessary to compensate individuals for any given decline in environmental quality. While the basic idea is simple, the theoretical and empirical details may be complex, and they may vary from application to application. This paper discusses the relevant conceptual and methodological issues and reviews applications to air and water pollution, noise nuisance, climate parameters, and natural hazards. 相似文献

I develop a new class of closed‐form option pricing models that incorporate variance risk premium and symmetric or asymmetric double exponential jump diffusion. These models decompose the jump component into upward and downward jumps using two independent exponential distributions and thus capture the impact of good and bad news on asset returns and option prices. The empirical results show that the model with an asymmetric double exponential jump diffusion improves the fit on Shanghai Stock Exchange 50ETF returns and options and provides relatively better in‐ and out‐of‐sample pricing performance. 相似文献

This article analyses the valuation of 192 structured products without a capital guarantee. In contrast to similar studies,
this investigation takes in both the primary and the secondary market. Its central element is a comparison of the implied
volatilities of the options contained in the structured products with those of comparable EUREX options. Generally speaking,
the results may well come as a surprise both concerning the scale of the phenomenon detected and its significance. Taken as
a whole, the results provide grounds for assuming that certain inefficiencies exist on the Swiss market for structured products
and that lead managers manage to exploit their quasi-monopolistic position in a rational manner.

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices. 相似文献
