Abstract—In this paper, we extend Hartman, Kwon(2005) In this paper we extend reference[13] endogenous growth
endogenous growth model in a straightforward way to include
endogenous technical change. The planner chooses the fraction of model in a straightforward way to include endogenous
physical capital to control pollution generated by production technical change. Our objective of the present paper is to
output process, human capital and technical capital are produced exmine whether the model is consistent with an

environmental s curve for realistic parameter values. The physical output generates pollution and that human capital
inter-temporal elasticity of substitution plays a very important and technical stock are produced without pollution. It means

more cleanly than most types of physical output. We also
