Aggregate Expenditure(in millions of dollars) What happens in the simple Keynesian model below if households expect lower income in the future and decide to save more today? Use the line mover tool to adjust the graph and then answer the question below. (Assume that investment varies directly with aggregate income.) 10000 9000 8000 7000 6000 5000 4000 3000 2000 1000 AE = Al C+1 0 1000 2000 3000 4000 5000 6000 7000 8000 900010000 Aggregate Incomeçin millions of dollars) What happened to output, income, and savings, as a result? What do economists call this phenomena? The decrease in consumption shifts the spending curve down, resulting in a lower level of output, income, and savings. Economists refer to the intended decrease in savings that results in a decrease in overall savings as the paradox of thrift. Output and income increase as a result of the decrease in consumption. In addition, savings will decrease when income increases. Economists refer to this as the paradox of thrift. Output and income decrease as a result of the decrease in consumption. Savings will also decrease when income decreases. Economists refer to this as the paradox of thrift. The overall increase in income, output, and savings O as a result of households' move to increase savings is known as the paradox of thrift.

Consider the following model. Expenditure is given by: E = C +1 + G. The consumption function is specified as: C = c0 +cY. We assume a closed macroeconomics system so that: Y=E. If the model parameters are configured such that I= 500, G=2000, c0=1000 and c=0.8, what will the level of consumption expenditure, C, be equal to? a. 4,375 b. 15,000 c. 14,000 Cd. 14,500

A certain country's GDP (total monetary value of all finished goods and services produced in that country) can be approximated by g(t) = 2,000-420e 0.07t billion dollars per year (0 ≤t≤ 5), where t is time in years since January 2010. Find an expression for the total GDP G(t) of sold goods in this country from January 2010 to time t. HINT: [Use the shortcuts.] G(t) = Estimate, to the nearest billion dollars, the country's total GDP from January 2010 through June 2014. (The actual value was 7,321 billion dollars.)

Consider a national income model as: Y= C + I0 + G Y= National Income C= (Planned) Consumption Expenditure  I0= Investment  G= Government Expenditure    Consider Y= 20trillion, G= 4.2trillion, I0= 3.8 trillion. Explain the key elements missing from the National Income model. Add a new endogenous variable to represent that missing element or endogenize one of the exogenous variables to address this issue. C= a+ b(Y-T0)   (a>0, 0<b<1) G= gY   (0<g<1)

We again assume asimple closed economy with GDP of 100 and:c0(autonomous consumption) = 20c1 (marginal propensity to consume) = 0.6I (investment) = 20.a) Now assume that c0falls by 5 (i.e. 5% of GDP), i.e. for any given level of output,consumption will fall by 5. Show the implied fall in the AD function in yourdiagram and show that output will fall by more than 5.b) Show that the multiplier is equal to 2.5, and hence that, in the new equilibrium,output will have fallen by 12.5 (i.e. by 12.5%)c) How big would the impact be if, say, c1 = 0.4 or c1 = 0.8? Explain the difference.

2. Question 2: Suppose that you estimate a model of the aggregate annual retail sales of new cars that specifies that sales of new cars are a function of real disposable income, the average retail price of a car adjusted by the consumer price index, and the number of sports utility vehicles sold (you decide to add this independent variable to take account of the fact that some potential new car buyers purchase sports utility vehicles instead). You use the data (annual from 2000 to 2014) and obtain the following estimated regression equation: CARS, = 1.32 + 4.91Y D; + 0.0012 PRICE, - 7.14 SUV (2.39) (0.00045) (71.40) 1 where CARS = new car sales (in hundreds of thousands of units) in year t, YD; = real disposable income (in hundreds of billions of dollars), PRICE = the average real price of a new car in yeart (in dollars), SUV = the number of sports utility vehicles sold in year t (in millions). You expect the variable YD to have a positive coefficient and the variables PRICE and SUV to…
