Be sure to show your work rounded your answer to 2 decimal places if necessaryA country’s GDP is defined by the following equation: GDP = Consumer Spending + Investmentspending. The economy of this country is closed and there’s no government. Investment spendingis defined by the following equation: Investment Spending = Investment (planned) + Investment(unplanned). Investment (planned) is fixed at 350. Consumer spending is defined by thefollowing equation: Consumer spending = 200 + 0.55 (GDP). And for this country, PlannedExpenditure = Consumer Spending + Investment Planned. Based on this information, attempt thefollowing questions:a. “Investment (unplanned) will be negative if GDP is 900” – showing work, test theauthenticity of this statement. b. How do you think GDP (and production) will change if the income of this country is 1500?Explain by deriving Investment (unplanned) for an income of 1500. c.

Suppose also that the marginal propensity to consume is 0.75, and that, if at full employment, the economy would produce an output and income of 3050 By how much would the government need to cut taxes (T) to bring the economy to full employment?Could you do C and D A country has an initial real output of $162 Billion. What would the final output be expected to be if:a. The government spends $15 billion on infrastructure and the MPC of the country is 0.35b. The government reduces taxes by $3.5 billion and the MPW of the country is 0.75c. The government makes no changes to taxes or spending.d.

- onsider a closed economy to which the Keynesian-cross analysis applies. Consumption is given by the equation C = 200 + 2/3(Y – T). Planned investment is 300, as are government spending and taxes. What is equilibrium Y? (Hint: Substitute the values of equations for planned consumption, investment, and government spending into the equation Y = C + I + G and then solve for Y.) What are equilibrium consumption, private saving, public saving, and national saving?Suppose that the marginal propensity to consume is dC/dy= 0.4 + (1 / sq. root of 3y + 10)(in billions of dollars) and that consumption is $9 billion when disposable income is $0. Find the nationalconsumption function C. Round numbers in your answer to two decimal places when appropriate.Suppose a closed economy has an aggregate consumption function given by C = 300 + 0.75Yd and generates $2200 output and income in equilibrium. Suppose also that the government collects a lump-sum tax of 300. How much will the private sector be saving total in equilibrium? (round your answer to the nearest whole value)

(Hint: Be very careful in your calculations. They are not difficult, but it is easy to make careless mistakes that produce dramatically wrong results.) (e) How much does the government collect in taxes when the economy is in equilibrium?
