Consider a production function for an economy:
Y = 20(L.5K.4N.1)where L is labor, K is capital, and N is land. In this economy the factors of production are in fixed supply with L = 100, K = 100, and N = 100.
a) What is the level of output in this country?
b) Does this production function exhibit constant returns to scale? Demonstrate by an example.
c) If the economy is competitive so that factors of production are paid the value of their marginal products, what share of total income will go to land?

Solow Growth Model Question: Consider an economy where output (Y) is produced according to function Y=F(K,L). L is number of workers and Y is the capital stock. Production function F(K,L) has constant returns to scale and diminishing marginal returns to capital and labor individually. Economy works under assumption that technology is constant over time. The economy is in the steady-state capital per worker. Draw graph. Next scenario is that the rate of depreciation of capital increases due to climate change...

Consider an economy that uses two factors of production, capital (K) and labor (L), to produce two goods, good X and good Y. In the good X sector, the production function is X = 4KX0.5 + 6LX0.5, so that in this sector the marginal productivity of capital is MPKX = 2KX-0.5 and the marginal productivity of labor is MPLX = 3LX-0.5. In the good Y sector, the production function is Y = 2KY0.5 + 4LY0.5, so that in this sector...
