In this research, the Market efficiency related to going concern entity and its Probability reflect on the price/earnings ratio (P/E) was tested that whether, when going concern entity evaluated above later it's PIE become near to industry's P/E and vice versa? In this research, one of the bankruptcy production models wdll- known as zargin Model is used for sorting and ranging the entities on the base of going concern, which its output data is limited on zero and one, indicates the probability of the bankruptcy and going concern of the entity. In the use of this model, since the model was prepared on the entitie's activity environment and its structure in the other countries and it wasnt consistent for Iranian corporation's activity environment, so after selection of the sample consisted of 40 corporations in the SEC, its coefficients are corrected and constituted with Iranian corporation's qualitative and in the along of doing research at first, the efficiency of the model was tested with the sample consisted of 14 normal and bankrupt and going concern probabilities for the sample corporations of the car industry was computed. Also as regards the evaluating high and low of the P/E ratio was problem, the amount of farness and nearness of the entity's P/E to industry’s P/E are adopted and computed as favorable parameter. Then the existence of meaningful correlation relationship between computed going concern relatively ability and amount of contradiction of entity's P/E than industry's P/E was tested. The results of study showed that there isnt any meaningful relationship between these two parameters in the level of supportable error of 5 percent and we cannot use the evaluating of differences between entity's PIE to find out the amount their going concern ability in the future.

After initial Pricing of stocks at Tehran stock exchange, security prices will fluctuate according to the market prices. The question is which theoretical model, the market price of securities, will follow? The aim of this study is to identify among the best theoretical models, a model, which can best define the market price. In this research, three valuation models which are best recommended in financial management literature are chosen, and the stocks which are traded at Tehran stock exchange are valued by them. Then the actual security prices, revealed by market are compared with those calculated values. The results of this study shows that if the required rate of return is calculated by CAPM, the Walter model compared to Gordon growth model and present value model of future cash flows, calculate security values closer to the market prices of the securities. The results also indicate when the fixed required rate of return of 40% is used; Gordon growth model will give values closer to the market prices of the securities.

The aim of this research is to find any relationship between productivity and profitability indexes; the fact that whether productivity level movement affects the profit movement or not? And if there is any relationship between them, how is it?

One of the most important characteristics of corporation is distinction between ownership and management. On this basis, manager exclusively available to access to apart of information and he/she is responsible to preparing and transferring financial information.

On basis of research result and considering of limit in available to financial information of some statistic popular corporations, managers are willing to manage the income in periods that corporation has loss or income, in order to increase the bonus; and in profitability periods, in order to smooth the income.

A conceptual framework of accounting can be decision based or accountability based. The choice critically affects the resulting framework. A framework that is decision based is centered on the decision maker, namely, the user of accounting information. Suppliers of accounting information might as well be inanimate objects since their interest in the now of information is not considered in this type of frameworks. A framework built on the accountability relation, on the other hand, focuses on the relation between the accountor, the supplier of the accounting information, and the accountee, the user of the accounting information. In a decision-based framework, the objective of accounting is to provide information useful for economic decisions. It does not matter what the information is about. More information is always preferred to less as long as it is cost effective. Subjective information is welcome as long as it is useful to the decision maker. In an accountability-based framework, the objective of accounting is to provide a fair system of information now between the accountor and the accountee. It is built upon the accountability relationship between the two parties. Based on the underlying accountability relation, the accountee has a certain right to know, at the same time, the accountor has a right to protect privacy. More information about the accountor is not necessarily better. It is perhaps better from the standpoint of the accountee the not necessarily from the overall accountability relation. Subjective information can seriously damage the interest of the accountor, even if it is highly useful to the accountee. Most conceptual frameworks seem to be decision based. They are unidirectional- oriented solely toward user. A conceptual framework that is accountability based must weigh the interest of the two sides; it is bidirectional.
