(四)教学方法与手段 课堂讲授，多媒体教学，课堂讨论或分组讨论。 第四章Growth and Policy (一)目的与要求 1.In the last chapter,we leamed that the rate of growth of potential output is determined by the rate of population growth,by changes in the level of natural resources,and by improvements in technology.In this chapter,we recognize that society's choices affect these parameters 2.The first part of this chapter investigates the forces that bring about technological change,focusing in particular on the new ideas generated by the process of capital investment,and the fact that it is difficult,if not impossible, for any individual firm to capture all the benefits of these ideas.It also looks more carefully at convergence-the question of whether economies with different levels of income will eventually achieve the same standard of living 3.The second part of this chapter looks at problems of population growth and development.Using examples from high growth and low growth countries,this section examines the role of prudent policy in influencing the growth rate of a country.

In this chapter, we recognize that society’s choices affect these parameters. 2．The first part of this chapter investigates the forces that bring about technological change, focusing in particular on the new ideas generated by the process of capital investment, and the fact that it is difficult, if not impossible, for any individual firm to capture all the benefits of these ideas. It also looks more carefully at convergence⎯the question of whether economies with different levels of income will eventually achieve the same standard of living. 3. The second part of this chapter looks at problems of population growth and development. Using examples from high growth and low growth countries, this section examines the role of prudent policy in influencing the growth rate of a country. （二）教学内容 1．主要内容 1） Growth Theory: Endogenous Growth y = ak Endogenous growth theory Constant and increasing returns to scale Private and social returns to capital Absolute and conditional convergence Stable and unstable equilibria 2） Growth Policy The poverty trap Growth in Asia The role of human capital
