Use the IS-LM model to determine the impact on output and interest rates of a one-time increase in the price level due to a large increase in oil prices. Using words, answer the following questions (and make sure to explain why things are happening to earn full points): What happens to the curves and equilibrium values in the affected market(s) (i.e., the money market and/or goods market)? Explain. What shifts in the IS-LM model? Explain. Are the equilibrium levels of interest rates and income in the IS-LM model different than before the increase in oil prices? If so, how are they different? Explain.
If there is a large increase in oil prices that increases the overall price level P, then assuming M is unchanged, the supply of real money balances M/P in the money market decreases. This leads to an increase in the money market equilibrium real interest rate for any given level of output/income. This is a leftward shift of the LM curve. In the IS-LM model, this results in a higher equilibrium interest rate and a lower equilibrium level of output/income. In the goods market, the increase in the interest rate decreases investment, which decreases planned expenditure and shifts the planned expenditure curve downward in the Keynesian cross, which results in a lower equilibrium level of output in the goods market.
Consider a competitive economy in which factor prices adjust to keep the factors of production fully employed. In addition, the interest rate adjusts to keep the supply and demand for goods and services in equilibrium. The economy can be described by the following set of equations: Y = AKα L(1 - α) Y = C + I + G C = C (Y - T) I = I(r) Suggest at least two policies that a government could use to increase the equilibrium quantity of investment in the economy and carefully explain how these policies produce this result.
Private Spending (Y-T-C)Public Spending (T-G)Y = C + I + GI = Y - C - GIf the private as well as public spending (consumption of goods and services) is decreased in an economy, the equilibrium quantity of investment would increase because then people would put more money in investments rather than purchasing goods and services, which would increase the demand for investment.For instance, assume Y = 20, C = 8, and G = 6. Then, I = Y - C - G = 6.Now, let's assume C = 5. Then, I = Y - C - G = 9As seen above, when the consumption decreases, Investment increases.Along with that, if the government cuts its spending, it would also help increase the equilibrium quantity of investment in the economy.For instance, assumeY = 20, C = 8, and G = 6. Then, I = Y - C - G = 6.Now, let's assume G = 3. Then, I = Y - C - G = 9As seen above, when the government purchases decrease, Investment increases.
