The pertinent question is whether scarcity of non-renewable energy resources limits economic growth. Given that the earth's natural resources are limited, the answer appears to be yes. However, there are two reasons to reject this question. Technological advancements that conserved resources may be able to eliminate resource scarcity. Additionally, countries can import resources from other countries. This paper aims to develop an endogenous growth model with stochastic exhaustible energy resources and use it to explain the economy's steady state behavior. We consider the uncertainty associated with extractable energy resources and then develop a stochastic growth model on this basis.Additionally, we solve this model analytically using the Stochastic Hamilton-Jacobin-Bellman method (SHJB method). Finally, for the Iranian economy, we apply the analytical solution. The primary findings indicate that as natural resource extraction becomes even more uncertain, the rate of economic growth slows, which results in a subsequent decline in the rate of resource extraction. Furthermore, we observe that the variance in energy extraction in the Iranian economy is approximately 0.22. Under these conditions of uncertainty, the optimal economic growth rate in a steady state will be 7.1 percent with an extraction rate of 1.1 percent.

This paper aims at estimating the efficiency of hydroelectric power plants (renewable energy resources) and thermal power plant (non-renewable energy resources) in Iranian provinces. Data Envelopment Analysis (DEA) approaches is applied to estimate the efficiency. The network is modeled as a linear system with multiple inputs and one output. Fuel cost, labor force, operation cost are used as inputs. Electrical energy delivered per year is used in the model as output. The study offers some detailed policies to improve the efficiency of the plants. Mean technical efficiency of hydroelectric power plant in 2011 and 2010 are 62% and 53%, respectively. Mean technical efficiency of thermal power plant in 2011 and 2010 is 82% and 77%, respectively. The results of the study indicate that mean technical efficiency of thermal power plant in 2010 and 2011 is higher than efficiency of hydroelectric power plants.

Abstract The main purpose of this paper is to obtain the optimal amount of expenses of government relating to the protection of property rights (PPRs). To achieve these purposes we have introduced concept of social intelligence with respect to PPRs and then developed different growth model from existing literature. In the second step the optimal share of government spending on the PPRs is calculated. The theoretical results show inverse relationship between budget deficits and government spending in the PPRs. In other words, with increasing amount of government deficit, government reduced spending of PPRs. The results of calibration for Iranian economy show that, the growth rate of spending to PPRs should be equal to 31 percent for having sustainable economic growth rate of 6 percent.
