Suppose you are a policy advisor who is responsible for developing a national level long term public investment policy. Suppose you are asked to discuss the effectiveness of investing on the efficiency of the current production technology and investing on the public education. Based on the model of human capital accumulation in Chapter 8 (endogenous growth model), discuss the key differences of these investment possibilities and explain which investment policy you would recommend and why. Discuss briefly what additional aspects of the real world you would consider when making such a recommendation which may be missing in the model?

This problem is discussing endogenous growth model! This question was given this way and there is no more information on it besides what I have provided here.... this IS the question. Class is intermediate macroeconomics.
