The purpose of this study was to compare various direct techniques of measuring attitudes toward risk. The Equally Likely Certainty Equivalent with a Purely Hypothetical Risky prospect (ELCE-PH), The Equally Likely Certainty Equivalent with a Hypothetical but Realistic Risky prospect (ELCE-R) and Probability of Winning Demanded (PWD) models were used to elicit the risk attitude of a sample of farmers. These methods were then compared and evaluated. The criteria employed were (1) sample respondent capability in answering questions, (2) means and corresponding risk attitudes classification and (3) distribution of risk attitudes. According to the first criterion, the results showed PWD technique is the best one. While there are no differences among the three direct techniques on the basis of the second criterion. Also, the findings indicate that respondent education and age, family education, level of hypothetical income and a greater explanation by other people during interview have an influence on respondent capability in answering questions. These characteristics should therefore be considered when choosing the appropriate technique.

Due to the lack of General Practitioners (GP) in the past two decades in Iran, increasing the number of General Practitioners has been on the strategic agenda for health sector. However, this was an appropriate action for the time but, these augments unfortunately continued without scientific considerations, while these were based on the needs of society in that time. This led to some problems for all sectors in the health system. Unemployment, misemployment, underemployment were the results of these policies. Government suffered from heavy cost of educating General Practitioners. the system faced with inequality in their performance as well. Because of the importance of the subject, this research is done for avoiding such problems. It uses mathematical and economic models and techniques to estimate the number of GP from 2006 to 2011, which is believed to be essential for the health system. In this research, Cob-Douglas production function and partial adjustment model have been used for estimating GP labor demand function, then using growth rates of variables and growth mean of the period for each variable, the needed number of GP has been estimated. The future need of GP for years of 2006, 2007, 2008, 2009, 2010, 2011 is respectively, 3864, 4507, 5282, 6224, 7384, and 9011. The elasticity is also calculated for the variables: (RInv), (RVA), (L). Point elasticities for the above variables are respectively 0.035, 0.041, and 0.01.

This paper aims to study some Muslim economists’ views towards pre- suppositions of demand theory in economics, benefiting from the method of analyzing rational behaviors, as well as considering the epistemology of utility. In economics in general and Islamic economics in particular, there not only exists a sharp difference in utility - as a basis for demand theory, but also, there are some vital differences in recognizing utility. Considering the differences here influences theorization of demand in Islamic economics.

Morteza Shahbazinia Assistant Professor of Law, Ministry of Science, Research and Technology  The Condition of payment form the heart of the guarantee. They determine the actual benefits for the beneficiary and the risk exposure for the account party/principal debtor. For example, it is the clause that payment will be made on the beneficiary’s first demandwithout any proof of default that renders this particular guarantee totally different from the traditional or accessory guarantee. On the other, aguarantee payable upon submission of an arbitral or court decision is in substance hardly different from the contract of accessory guarantee. While different as regards the degree of default, all conditions of payment share a common characteristic, namely their documentarynature. All of them require the submission of documents and the bank’s duty is confined to examining whether these documents comply with the documents prescribed in the guarantee. It is this documentary nature of the conditions of payment, which enables the bank to perform its function.

This paper examines urban residential water demand for the city of Zahedan in Iran using the data over the period 1999 – 2006. The continuously intensifying scarcity of water resources is a crucial problem in almost all contemporary societies. Even in areas where there are adequate quantities of water. The problem of scarcity is usually confronted through the deterioration of water quality resulting in increasing costs for certain water uses. In the framework of water demand, it is vital to analyze and understand the characteristics of water demand. There are several important questions that need to answer. They are as follows: How the demand is formulated? Which factors determine the demand? How the demand responds to the changes in income and the cost of water? Stone-Gray approach is used to model and answer the above questions. The results show that the main determinants of residential water demand comprise water price, income, and temperature. The price elasticity of demand equals –0.06 while the income elasticity equals 0.062. Finally, the findings confirm that the minimum water requirements are 95 liters per person per day.

The topic of demand for sport has attracted substantial attention in the fields of sports economics in recent decades. Sport contest is one of the important products in the sport industry. Understanding the factors that affect the demand for this product can help football managers to earn more money. The main goal of this article is to identify the factors affecting demand for Iranian Football Premier League. To this end, demand function for Premier League Football is specified and estimated using the data during 2005 - 2006 seasons. The results reveal that match variables as well as economic variables have significant effect on the demand for Premier League Football in Iran. The results of the estimates show that Football is an inferior good and demand for Football is declined in the cities that have greater population. Since the uncertainty of outcome can not be explained by the demand, the numbers of attendance in match decreases at the end of seasons.

According to the important role of linguistic factors in reproducing social power and controlling the mind of subjects by redistribution of ideologies the present research tries to explore the underlying levels of surface aspects related to the structural organization of the discourse which can be led to appearance of a new and deep insight. Thus, mastering discourse concepts is an appropriate instrument for a realistic analysis of group’s minds and ideologies. According to the Discourse- Society- and knowledge , Van Dijk (2006) concludes that, each human being, in order to reach the goal of persuasion of the audience, tries to magnify and emphasize his positive actions and minimize the opposing party's attributes. In parallel to this effort, he tries to mitigate its negative qualities and the positive features of the other party. Strategies used to this end can be classified as: actor description, categorization, comparison, euphemism, disclaimers, evidentiality, example/illustration, generalization, number game, hyperbole, irony, populism, norm expression, national self-glorification, negative other representation, metaphor, implication, presupposition, lexicalization, victimization, vagueness, positive self-presentation, polarization/ Us – them categorization,  Burden and Authority. By naturalizing the text and studying structures, critical discourse analysis tries to eliminate the power relations, discourse-based elements of texts and hidden ideologies in texts.in entrance to the concrete layers of language, human wants to select between options and alternatives. Each selection between alternatives shows the actors ideology, knowledge and attitudes. One of these linguistic tools is the manner of social actor’s representation. Each manner of naming shows the users’ attitude about the named actor. In this research writers tried to study the manner of naming family court actors by divorce demanding women. To do this, we attended 20 meeting of the General Court and family counseling center of Zahedan- Iran and recorded the divorce demanding women’s Statements. With regard to the prohibition of the use of audio and video equipment or any kind of electronic means in the court environment, only a written record of women's statements has been limited. After collecting, data were studied based on Van leeuwen (2008) theory to sort different types of actor’s representation. After that in order to study the goal of each type of naming and representation, each class of representation was studied according to Van Dijk (2006) theory. Research results showed that divorce demanding women represent the others by three type of naming. The first was relational identification, the second was passivation and the third was mitigating the others negative properties and magnify positive characteristics of themselves

The aim of this paper is twofold. It first investigates the demand for international reserves using panel data for 32 developing countries during the period 1975 – 2004. To this end, an Error Correction Model (ECM) approach is employed to estimate the empirical model and then a capital asset pricing model (CAMP) is used to determine the composition of the foreign exchange reserves. A dummy variable is included in the model to consider the effect of changing exchange rate system on the demand and the composition of international reserves. The results show that there is a negative relationship between exchange rate flexibility and the demand for international reserves.

Due to the poor development of the domestic financial markets in Iran, a lack of efficient tax system and some restrictions on foreign borrowing in recent decades, the government budget deficit was mainly financed through borrowing from either the central bank or through the selling of the oil revenue dollars to the central bank, both of which led to increased monetary base. It caused to increase the rate of inflation as well. While printing money creates revenue through seigniorage for the government, it decreases the purchasing power of the money and people prefer to hold less cash money because of the inflationary effects of monetization of budget deficit and finally it will reduce the seigniorage revenue of the government. The aim of this article is to analysis seigniorage revenue in Iran using money demand function approach. The Johansen-Juselius Cointegration technique is used to estimate the empirical model using annual data over the period 1961-2007. The results of estimates show that semi elasticity of inflation rate is negative of 5/59 and the elasticity of GDP per capita is positive of 2/36 in long run. After first oil boom, seigniorage-maximizing rate of inflation, except during the period of war, is lower than the actual rate of inflation. According to the result, the economy is generally on the wrong side of the Laffer curve. The result does not depend on whether the expectations of agents form adaptively or rationally.

In a mobile ad hoc network, there are some features such as the ability to exploit multipath effect for information exchange with high reliability and low error rate. dealing with the aggressors and discovering the path in data transmission are of importance. Approaching these goals ends in network promotion and efficiency. In this paper, the designed protocol is able to discover multipath for information exchange with high reliability. The designed network has advantages such as resistance against error occurrence, decreasing the effect of the aggressors and discovering the path in data transmission. The network security is based on the desired encoding and encryption and it provides increased speed and mobility of the network performance and efficiency and reduces the weaknesses of the security system. With increasing the speed of the nodes and density of the network, the receipt of the packets increases about four percent which causes one percent increase in packets transition. At the same time packet overhead decreases 12% on average.

Economic environments have a profound effect on the growth of the insurance industry. History has shown that, although the performance of the insurance industry is closely linked to economic conditions, it has been able to survive in different economic environments. This study is undertaken to examine the demand for life insurance in Iran from a macroeconomic perspective. More formally, the work was carried out in order to study the interaction between the macroeconomic and demographic variables (i.e financial development, income, inflation, interest rate, price, stock market return and life expectancy) and the demand for life insurance in order to seek evidence of their relationship in the context of Iran for the period 1369-83(1990-2004). The major findings of this study indicated that the saving deposits rate, price change, income, stock marked return and life expectancy in insurance are important macroeconomic variables associated with the demand for life insurance in Iran. Further a change in the price of insurance has a significant negative relationship with the demand for life insurance. These findings have an important implication on policy formulation and also for the policy markers in developing pricing strategies. for the policy makers.

This paper seeks to respond to this major question that if Iran accedes to the World Trade Organization (WTO) and observes copyrights, in the realm of intellectual property, what demand and supply changes would occur in Iran’s book market. To respond the above question first some instances of breaching the copyrights in book publishing sector is investigated. Then calculating the price and income elasticity, the impact of observing the copyrights on price and income, and therefore on the demand and supply for books in short term is demonstrated. The findings of this research reveal that with accession of Iran to WTO and observation of copyright, some of the subsidies to the book sector must be terminated, and also the non-national authors would receive royalties. With elimination of subsidies and payment of royalties book price will increase by an average of 7.5 percent and demand would decrease by 13.35 percent. But, supply will show less sensitivity and its increase in short term would be insignificant. Yet, as experienced in other countries, for numerous reasons such as entering the international markets and increased quality, the printing volume of books will increase. In long term, the experiences of other countries have shown the same trend.

Energy is aconsidered as one of the major inputs of production along with other inputs such as labor and capital that contribute to the production process. Moreover, most energy sources have fossil origin and are irreversible, so on the one hand, the basic features of the finitude of other energy inputs to production are distinct and the necessity of energy saving and the possibility of substituting them with the renewable forms are self-evident. Industrial energy demand analysis has always been one of the leading fields of research in economics. This issue is more critical in the case of developing countries, especially those with transitional experiences. In this paper, third generation of dynamic factor demand models for the Iranian manufacturing industries is estimated to analyze the speed of adjustment in factor demands. Using the quadratic functional form, this result was the elimination of energy subsidies in the short term which has a great impact on the industry to reduce energy demand. But, it is believed that in the long run, the intensity of this effect will be diminished. Furthermore, the results show that the speed of adjustment in capital stock of factory industry is very low.

In recent decades, due to water crisis, most countries have been more interested in new policies for managing water demand instead of regulating the water supply. In dry and semi-dry areas of Iran such as Fars province, water scarcity is not only the important factor that impedes economic development but also special input in production. Drought in year 2007 could be considered as a risk of crisis in water supply. So, the purpose of this study is managing water demand through economizing surface water and groundwater resources which is of special importance in the region. It is self-evident that agricultural economy has a close relationship with water management. In this research the standard Positive Mathematical Programming (PMP) method is used to calibrate the agricultural sector model. A two-stage stratified random sampling through personal interviews of Bakan from Eghlid farmers has been applied, where abundant water resources and groundwater exist. By selecting a real sample of farms, model calculation for both areas is carried out. Two scenarios are identified. In the first scenario, by using PMP model for each group from water resources are calculated separately. They differ in terms of net revenue which is because of overly cost of construction and operation of wells between the two groups of surface water and groundwater. Results show that 10% decrease in water supply or doubling the prices will not change the optimal crop pattern in comparison to the base pattern. The results of model calculation shows that through running new irrigation methods (intensive irrigation) and also by effective pricing policies, investment can be encouraged in the water sector and in the area and therefore, through optimum management of water demand the water resources can be saved and any form of waste avoided.

     The main goal in this research is to survey and determine the actual structure of the demand function through the BOX-COX consumer goods demand system which includes various forms of demand functions. Using nested and non-nested methods the estimation of consumer demand function is done. Nonlinear seemingly unrelated regressions are also used for the periods of 1982- 2007 via the combined statistics of income groups in urban areas in order to calculate  uncompensated price elasticity and expenditure elasticity associated with the demand function estimate. Results of nested and non-nested tests show that the BCDS and AIDS models are near performance. The elasticity figures resulted from the BCDS and AIDS models have also revealed that food group is an essential one, social affairs (clothing, health, leisure and education) are regarded as almost luxury, and miscellaneous group (transportation and others) is quite luxury. But the group of housing (housing and furniture), in the BCDS model is almost luxury and in the AIDS model considered as essential. The elasticity of demand was confirmed by the demand law and cross elasticity of demand has also shown that the food group compared with the social affairs is considered as supplementary and to the group of housing and miscellaneous is regarded as a substitute. The social affairs group compared with the miscellaneous group is supplementary and to the housing group is a substitute and finally the miscellaneous group is considered as a substitute to the housing group.

In this paper, the results of a statistical study on inelastic displacement ratio for structures subjected to pulse like near fault ground motions were presented. This study is important because, the results can used for evaluating inelastic displacement demand of structures with known lateral stiffness and strength subjected to near fault ground motions. Inelastic displacement ratio were computed from the response of single-degree-of-freedom systems having 6 level of strength reduction factor when subjected to 61 pulse like near fault records. The influence of period of vibration normalized by period of peak spectral displacement, strength reduction factor, period associated with velocity pulse TP, earthquake magnitude and distance to the source, post-yield stiffness and hysteresis behavior of structure on inelastic displacement are evaluated. Results indicate that strength and stiffness degrading in short period region increase inelastic displacement demands. Finally, a simply equation for estimate the mean of the inelastic displacement ratio for structures subjected to pulse like near fault ground motions is proposed.

In this paper, the results of a statistical study on inelastic displacement ratio for structures subjected to pulse like near fault ground motions are presented. This study is important because the results can be used for evaluating inelastic displacement demand of structures with known lateral stiffness and strength subjected to near fault ground motions. Inelastic displacement ratio is computed from the response of single-degree-of-freedom systems having 6 level of strength reduction factor subjected to 61- pulselike near fault records. The influence of period of vibration normalized by period of peak spectral displacement, strength reduction factor, period associated with velocity pulse TP, earthquake magnitude and distance to the source, post-yield stiffness and hysteresis behavior of a structure on inelastic displacement ratiois investigated.For more study on the strength and the stiffness degradation effects on inelastic displacement, three type of hysteresis behavior have been considered. The first type iselasto-plastic behavior. Elasto-plastic behavior is generally used to represent the non-degrading hysteretic behavior. Second and the third typesarethe stiffness degrading and the strength-stiffness degrading hysteretic behavior.Results indicate that strength and stiffness degrading in short period region increases inelastic displacement demands. Further the period associated with velocity pulse plays a main role in inelastic displacement and has a significant effect on it. It is found that strain hardening can reduce inelastic displacement relative to system with perfectly elasto-plastic hysteresis behavior. Magnitude and source to site distance have little effects on inelastic displacement. Finally, a simple equation is proposed for estimating the mean inelastic displacement ratio for structures subjected to pulse like near fault ground motions.

On one hand, the skill-based technologies increase productivity and output, reduce inflation and raise income. On the other hand, human skills are essential for implementing, adopting, utilizing physically and practically of modern and imported technologies and serve a complementary role in this respect. In the present paper, an attempt has been made to evaluate the relationship between the domestic research and development capital stock and technology imports with skilled and unskilled workers in Iran from 1971 to 2006. To do this, a translog cost function was estimated with seemingly unrelated regression method. The results indicate that the technology and its spillover are complementary to the skilled labor and substitute for the unskilled worker. In addition, the results illustrate the existence of a complementary relationship between capital and skilled labor and a substitution one with capital and unskilled worker.
