When saving = Investment, show that the trade balance equals the government spending balance?
When saving = Investment, show that the trade balance equals the government spendig balance
What is the theory of New Keynesian economists
Qno.2 Assume that an economy is initially operating at the natural rate of output (full employment output). Use the AD-AS model to illustrate graphically the effects on price and output of an increase in government spending and a decrease in the cash rate. Explain your assumptions with respect to the range of aggregate supply of your analysis.
What is meant by state in the solow model? Explain how golden rule is different from steady state.
Consider following information from the Solow model in a continuous time, π = ππ
π β ππ,
πΜ = ππ(π) β (π + π + πΉ)π, π = π + π, where π =
π²
π¨π³
, g-is growth of technology, n-is labor force
