This paper focuses on the role of uncertainty about the number of surviving children. The survey discusses the effects of declining mortality rates on fertility, education and economic growth. The construction of the paper is an OLG model in which individuals make choices about fertility decision over their lifetimes subject to uncertainty about the immortality. The simulation of model using actual changes reveals the fact that if the uncertainty about child survival enters to growth model, the population becomes an inverted u-shaped function of income per capita. As the mortality rate and thus uncertainty falls, the precautionary demand for children decreases. Furthermore, lower mortality encourages investment in children’s education .Also the calibrated version of the model using realistic estimates demonstrates that at low levels of income, population growth rises leading to Malthusian steady-state equilibrium, whereas at high levels of income population growth declines leading to a sustained growth steady-state equilibrium.

One of the important targets of the economic planning is economic growth via enhancement of the labor productivity. In this regard, education expenditures play a crucial role. This study aims at investigating the effect of education expenditures on the level of human capital and economic growth through a computable general equilibrium approach. The data on economic variables and social accounting matrix belongs to the year 2001. Three scenarios on education expenditures are defined and their effect on human capital and economic growth are estimated. The results show that education expenditures have positive effects on economic growth and human capital. A 50% increase in education expenditures in the first period causes 3.81 and 5.8 percent increase in human capital and economic growth respectively. In the second period, the same increase in education expenditures affects human capital and economic growth positively by 5.4 and 7.3 percent respectively. Although separating the economic growth into human and physical factors in the first period shows that there is no relationship between human capital and economic growth, but in second period this separation causes a relationship between the two factors.

The growth of non-communicable diseases, and the enormous costs of health care, has led policy makers to focus on “education”, as an effective instrument to improve the public health. Recent empirical studies show that education can improve health and increase life expectancy via ameliorating the life style. The main objective of this paper is to investigate the effect of ‌education on health in‌ Iran over the period of 1974- 2010. Health ‌production function is defined based on the Grossman (1972) model.‌‌ The empirical model has been estimated by using co-integration technique and error correction model.‌ Separation of short and long-term effects and estimate of impact‌ by education’s temporary and permanent lag time changes on health is considered the  innovation aspect of  this research. The results of model estimation indicate that there is a positive and long-term equilibrium relationship between health and education. Based on evidence obtained, education plays a key role in health improvement. Empowering people by investment in their education can prevent many non-communicable diseases. Diseases that are imposed by our incorrect life style. Today we believe that an active participation of elementary and high schools, higher education, and mass media can ameliorate the health statue of society.
