- I need help with parts (f) and (g) of question 2arrow_forwardSuppose the per-worker production function is: y = A(1-gA) Where ga is the fraction of all workers that produce technologies. Further, suppose the growth of technology is given by the following equation growth of A = (g//m)(L) Suppose L = 1 and m = 7, and that initially ga = 0.7. If ga fell to 0.8 the level of output per %3D worker would: fall Impossible to say rise stay the samearrow_forwardProblem 2 In class, we argued that if people could accumulate human as well as physical capital, the production function would look like the "AK" production function. (a) If the production function is AK and the savings rate is constant at rate "s", and the rates of depreciation and population growth are 8 and n respectively, what would the growth rate of the economy be? (b) What would be the macroeconomic consequences of increasing the savings rate in this economy? Explain using the model and intuitively. (c) What would be the consequences of an increase in fertility in this economy? Are these consequences good or bad? Is this answer unambiguous? (d) How are human and physical capital different from one another in the way they evolve from period to period? (e) Does human capital have an upper limit? If it does, what is the resulting production function when this is reached and the growth rate of the economy? If it doesn't have a limit, what is the resulting growth rate of output as it…arrow_forward
- Consider now the two-period model in general equilibrium, so that prices, investment and labour supply are endogenous, i.e. the production economy. Analyse and carefully explain graphically and in words the general equilibrium effects of a decrease in TFP(total factor production) for a benchmark economy with no frictions.arrow_forwardGiven the following aggregate production function: Y = K0.25 (AL) 0.75, where technology A grows at a fixed rate: A=g>0 (f) Find the steady state solution algebraically for output per efficiency worker, ỹ, where (i = 1,2). Show all workings. (g) Outline and explain the behaviour of per worker variables along the model's balanced growth path.arrow_forwardPlease assist to solve the below question. Suppose an economy is on a balanced growth path in a simple Romer model, as described in the text, where aggregate output is: Y, = A,Lyt, law of motion of ideas (idea production function) is: AA++1 = ZA“, Lat ; labour resource constraint is: Ly +Lat = L, and the allocation of labour is: La = IL, %3D where z is a productivity parameter of the researchers, Ao is the existing stock of ideas at time, t = 0, L is the total population and assumed to be constant, and i is the constant fraction of population who works in the research sector. Suppose in year 2030, research productivity z rises immediately and permanently to the new level z'. а. How would the growth rate of ideas behave if a <1? b. Assuming a = 1, solve for the new growth rate of knowledge and growth rate of output per capita. С. Assuming a = 1, sketch the graph of Iny against time t. d. Why might research productivity increase in an economy?arrow_forward
