In recent decades and especially in developing countries, the trade of services has faced an increasing trend. The export of services can improve trade balance, economic growth, employment as well as development of merchandise sector. This paper uses a descriptive and analytical approach and intends to evaluate performance and factors affecting the total export of services and particularly the export of technical and engineering services in OIC selected countries by applying panel data method.
The results of estimating the performance indicators and comparative advantage of technical and engineering services export indicate that between years 1994 to 2010, Iran's position among these countries has improved. In our analysis, factors such as GDP per capita, real effective exchange rates, inflow of foreign investments, communication infrastructures and also being member of two trade blocs -ECO and D8- have significant and positive effect on the total export of services and also the export of engineering services. Thus, it is necessity for governmental institutions and private sector in Iran to plan and prepare to further develop the export of services.

House price changes in Iran is a category for thinking about in recent years and also different studies has been done on determinants of housing supply and demand and its price. However, this study deals with causality relation between house price and its determinant factors by seasonal data in Tehran between “1994-2006". In this study, Vector Error Correction, is used to estimate the model. Moreover, Wald test is utilized for the study of causality relation in long-run and short-run. The results show that all of the model variables can be significantly determinant of house price. In short-run, land price, the wholesale of building materials, and gold price (as substitution market) have a bilateral causality relation with house price. Forthermore, there exists a unilateral causality among the average of household income and private sector investment in house building, as complete buildings, with housing price. Nevertheless, in the short-run Granger causality between house price and interest rate was not confirmed. On the other hand, the high significance of the coeffeceint of partial error correction in all of the estimated equations as well as integrated tests with model dependent variables reveals existence of a long-run relation.
