Consider the human capital growth model. Let us make the following changes. Depending on whether the current calendar year is an odd or even number, the efficiency parameter of the human capital accumulation technology changes between 5.15 and 2.04. In particular, when the calendar year is an odd number (for example in years 1 and 3) the parameter b is 5.15 and z is 6. However, in even years (for example in years 2 and 4) the parameter is 2.04...

Consider the Solow growth model with the following production function where y is output. K is capital, s is the productivity and is labor. Assume that 0 < α < 1 Further, suppose that labor grows at a constant rate n. That is. 1 + n. Also, assume that capital depreciates at rate d and that gross investment in capital is fraction s of output. a Letting k-N, obtain the law of motion for capital accumulation...

Consider a version of the Solow model where the population growth rate is 0.05. There is no technological progress. Capital depreciates at rate ? each period and a fraction ? of income is invested in physical capital every period. Assume that the production function is given by: ?t = ?t1/2 ?t1/2 where ?t is output, ?t is capital and ?t is labour. a. Derive an expression for the accumulation of capital per worker in this economy, i.e. ∆?t+1 where ?t...

Suppose the production function is given by ? = ?^a?'^1-a, where Y is output; K is capital stock and N is Labor (look Appendix in Chapter 16). a. Is this production function characterized by constant return to scale? How? Show the work. b. Write this production function as a relationship between output per worker and capital per worker. c. If saving (S) equals investment (I), and S = sY, where s is saving rate, what is the corresponding investment per...

8. Consider the following production function Y = AK0.3(NH)0.7 where Y is GDP, A is total factor productivity, K is capital, N is employment and H is human capital. Denote by P the population of the country. Thus, Y/P is per-capita GDP and N/P is the fraction of the population employed. What is the contribution of the fraction of the population employed (N/P) to the growth rate of per-capita GDP (Y/P)? (a) Growth rate of N/P. (b) Growth rate of...
