Assume a Cobb-Douglas production function where the share of capital and labor is each 1/2. If the growth in total factor productivity is 1% and labor and capital each grow by 2%, then O output growth is 5% and the marginal product of capital is 2Y/K O output growth is 3% and the marginal product of capital is Y/(2K) O output growth is 5% and the marginal product of labor is (2Y)/N O output growth is 3% and the marginal product of labor is Y/(2N)A difference between the Keynesian model of income determination and the IS-LM model is that in the Keynesian model aggregate demand is determined by_____, in the IS-LM model aggregate demand is determined by O fiscal and monetary policy; fiscal and monetary policy O autonomous spending and fiscal policy; autonomous spending, fiscal policy, and interest rate Supply of real balances; supply of real GDP only fiscal policy; only monetary policyAssume an endogenous growth model with labor augmenting technology. The production function is Y = F(K,AN), with A = 3(K/N) such that y = 3k. If the savings rate is s = 0.04, the rate of population growth is n = 0.03, and the rate of depreciation is d = 0.02, what is the growth rate of output per capita? O -1% 3% 7% 4%
