By employing conditional variance modeling and Granger causality test, we specified and compared the linkage between inflation and inflation uncertainty in Iran and three other OPEC members. To achieve this purpose we used consumer price index quarterly data for the years 1985-2009. The results suggest strong evidence that shows that in all these countries the increase in inflation leads to increase in inflation uncertainty. But in reverse, only in Iran and Venezuela, a causal relationship from inflation uncertainty to inflation can be found.

The main objective of this research is to investigate the effect of loyalty on the repurchase of the customers of the dairy products. In order to gather the information in the field of investigation, two methods of library studies and field studies using the index cards and questionnaires tools for measuring the research variables was used. The research population was the customers of the products of the Kaleh dairy company, which used to purchase from Refah chain supermarkets of Tehran city. The random cluster sampling method for determining the respondents to the questionnaires was used. A total of 450 Questionnaires was distributed that 386 responses of them were usable for data analysis. Data were analyzed using the structural equation modeling (SEM) techniques. The research findings indicate that the customer trust, involvement, commitment and word of mouth does not have any direct effect on their repurchase. But the customer satisfaction has direct effect on repurchase. Also the customer involvement has direct effect on their satisfaction. On the other hand, the customer satisfaction has direct effect on their trust, commitment and word of mouth which among them the customer's satisfaction has the most effect on the word of mouth of the dairy products.

Forecasting business cycles is very important in macroeconomic and it is an important part in process of economic decision-making and policy. In recent years, non-linear models have been considered more for forecasting economic variables and application of these models has been made a significant improvement in modeling of the behavior of variables in the area of macroeconomic and particularly financial economics. This article provides a convenient and powerful model for forecasting business cycles by using smooth transition regression (STR). The results show that very little error that indicates model performance is acceptable.

Stock Liquidity risk can be thought as one of the factors affecting the investors expected return. Clarifying a measure according to the specifics of the company to measure the stock liquidity could help the investors to make better decisions. In this study, we examine the relationship between assets liquidity and stock liquidity in hole of druggist firms listed in Tehran Stock Exchange during the years 1387 and 1388. We use the turnover ratio .The results show that there is a significant relationship between the assets liquidity and stock liquidity. This relationship depends on market expectations regarding the deployment of the firm's liquid assets. Thus our hypothesis links stock liquidity to managerial actions that change the liquidity of the firm's assets, such as investment financing, and payout. Consistent with my prediction, I find that after controlling for firm fixed effects, increase in asset liquidity increases stock liquidity, too. The relation is stronger when the manager is less likely to convert liquid assets into illiquid assets such as for low market to book, during economic recessions, and when expected payout is high.
