this paper examines the accuracy of valuation models in providing reasonable estimation of the market values of listed companies in tehran stock exchange (tse). six valuation models including gordon growth model, two stage dividend discount model, adjusted present value, price to earning ratio and residual income were examined in this study. in addition, three proxies represent the market value...

This paper investigates the potential implications of valuation error for the accuracy of investment performance measures of property portfolios. Previous empirical research on valuation error is reviewed It is argued that there is considerable evidence to suggest that valuations are prone to error. A simulation approach is used to model the effects of valuation error on a number of hypothetica...

Performance-dependent options are financial derivatives whose payoff depends on the performance of one asset in comparison to a set of benchmark assets. In this paper, we present a novel approach for the valuation of general performance-dependent options. To this end, we use a multidimensional Black-Scholes model to describe the temporal development of the asset prices. The martingale approach ...

The aim of this paper is to generalize the‎ ‎notion of almost valuation domains to arbitrary commutative‎ ‎rings‎. ‎Also‎, ‎we consider relations between almost valuation rings ‎and pseudo-almost valuation rings‎. ‎We prove that the class of‎ ‎almost valuation rings is properly contained in the class of‎ ‎pseudo-almost valuation rings‎. ‎Among the properties of almost‎ ‎valuation rings‎, ‎we sh...

In a Markovian stochastic volatility model, we consider financial agents whose investment criteria are modelled by forward exponential performance processes. The problem of contingent claim indifference valuation is first addressed and a number of properties are proved and discussed. Special attention is given to the comparison between the forward exponential and the backward exponential utilit...

Although anecdotal evidence and individual case studies suggest that effective knowledge management (KM) initiatives contribute to superior firm performance, quantitative empirical investigations are scarce, and more to the point, most of them are based on perceptions of survey participants embedded in the firms being studied. Moreover, studies analyzing the question of whether superior KM perf...

The aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎It is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...
