According to the results of MoreAccording to development economists in the modern theory of economic growth, total factor productivity is affected by domestic research and development costs .It also depends on the accumulation of foreign R & D and the volume of imports. According to the results of this research, total factor productivity in agriculture of Iran's is dependent on domestic and foreign R & D expenditures and the volume of imports from Partners. For this purpose, a model of agricultural total factor productivity to Iran with the help of ARDL econometrics approach and the time series between 1980 - 2010 was estimated. The results showed that effect of domestic research expenditures on agricultural productivity is less than of foreign investment in research and development. In this study, intermediate inputs and goods imports have a positive and significant impact on agricultural TFP in the long-term. Climatic conditions as a symbol of rain, has a positive effect on agricultural total factor productivity. Based on this model, it is suggested that a significant proportion of GDP allocated to domestic agricultural research. Furthermore, it is essential that agricultural imports from countries with a high volume of research and development to be done to enhance the size of productivity in this sector.

Given the bank-oriented financing system of most countries, it is important to know the ways to measure and increase the level of productivity in banks. Accordingly, the purpose of this study is investigating the short-term and long-term causality between capital adequacy, labor and Total Factor Productivity (TFP) in a set of 10 banks listed on the Tehran Stock Exchange in 2010-2019. So, Dynamic Ordinary Least Squares (DOLS) method, Vector Error Correction Model (VECM) and Wald test have been used. According to the results, in the short run, a one-way Causality from capital adequacy to TFP is obtained. In the long run, the two-way relationships between labor and capital adequacy variables with TFP are positive. In this study, the error correction term, which indicates the speed of short-term adjustment to long-term equilibrium, has been evaluated Manuscript profile -

Basedon that, countries have invested a great deal to increase total factorproductivity. In this article, the effect of human capital, openness to tradeand inflation on total factor productivity has been investigated in Iran during1976-2012. We estimated total factor productivity TFP, using Malmquistindex. We also investigated the effects of various factors on productivity,using Johansen and Juselius’ co-integration techniques. Our findingsindicate that human capital has a positive effect on productivity. We alsofound that openness has a positive and inflation has a negative effect on totalfactor productivity in Iran Manuscript profile -

The results obtained from the study show that 17 countries have the efficiency rate under 0.9, and that from the viewpoint of technical efficiency, only Kuwait is placed on the boundary function of production. Also, from the viewpoint of management efficiency, countries such as Azerbaijan, Bulgaria, Georgia, Kazakhstan, Kuwait, Kyrgyz Republic, Lithuania, Mongolia, Ukraine, and Tunisia have the highest rate of efficiency.

For this, a stochastic Frontier production model was estimated for 135 manufacturing industries over the period 1379-1393. The findings showed that technological progress in 21 industrial groups has been grew on average 12 percent annually. In relation to technical efficiency many of technical industries have been weaken in using exist technologies or have been inefficient technically. The third factor findings showed that Iran’s manufacturing industries have been utilized from scale effects. In relation to allocative efficiency, also, all groups have experienced negative growth except Recycle group. In result, among components of total factor productivity, allocative efficiency has been more unfavorable and it refers to in Iran’s economy the resources allocate in unfavorable. On the base of the results, improvement in financing system, increasing in private sector capacitance, improvement in business space are suggested. Manuscript profile -

9 - The Effects of Financial Integration on Total Factor Productivity In the Iranian Economy; Evidence for Vector Autoregressive Distributed Lag
masoud taherinia Ali Hassanvand Morteza HabibizadehAbstractFinancial integration through increasing the level of investment in countries can have many positive effects on macroeconomic variables such as employment, economic growth, increasing the volume of international trade and ultimately the productivity of countries MoreAbstractFinancial integration through increasing the level of investment in countries can have many positive effects on macroeconomic variables such as employment, economic growth, increasing the volume of international trade and ultimately the productivity of countries. This study examines whether fiscal integration in Iran can affect overall productivity growth and whether integration policies and subsequent fiscal integration can be among the policies that are needed. Should these countries adopt for their economic integration process? This study investigates the role and effects of financial integration on the productivity of total factors of production through the vector Autoregressive Distributed Lag during the period 1379-1398 for the Iranian economy. The results of estimating the model in the short and long term indicate a positive and significant relationship between financial integration and productivity during the selected time period. Also, variables such as trade openness and domestic investment have a positive relationship with productivity, but the inflation rate has had a negative impact on overall productivity.

This research also attempts to study the direction of causality between the income inequality and total factor productivity (TFP) in Iran. Using ARDL methods in the period at 1980 to 2008, empirical results showed that there is a negative relationship between income inequality and agricultural TFP in rural areas of Iran. Hence, additional investments in rural education and agricultural R&E have significant impacts on income inequality. Findings showed also that the Ahluwali hypothesis of the relationship between income inequality and agricultural TFP in Iran's rural areas is not ejected Manuscript profile -
