An economy is initially described by the following equations: C = 60+ 0.8(Y-T) I = 120-5r M/P = Y-25r G = 200 T = 200 M = 3000 P = 3 a. Derive and graph the IS and LM curves. Use the accompanying diagram to graph the IS and LM curves by placing the endpoints at the correct location, then place point A at the equilibrium interest rate and level of income.

Linear equations for the consumption and saving schedules take the general form C = a + bY and S = -a + (1 - b)Y, where C, S, and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule.a. Use the following data to substitute numerical values for a and b in the consumption and saving equations. b. What is the economic meaning of b? Of (1 - b)? c. Suppose that the amount of saving that occurs at each level of national income falls by $20 but that the values of b and (1 - b) remain unchanged. Restate the saving and consumption equations for the new numerical values, and cite a factor that might have caused the change.

The Bureau of economic analysis announced today that gross domestic product, the widest measure economic activity, grew in a meager 0.9% annualized rate in the third quarter compared to the first six months of 2018 the US economy in the first 3 quarters of 2019 grew just 1.6%, a pronounced slow down relative to the 3.9% growth in the second half of 2018. Some of this slowdown can be explained by a negative contribution from inventory investment, which contracted 0.9% in the third quarter. There’s plenty to worry about in this report, as it showed us Retail sales Fell for the first time in seven months in September, although overall consumer spending which comprises about 66% of the US GDP activity was up 0 .4%. Capacity utilization also decreased 0.4% in the third quarter to 74.5%.1. Write a phrase from the article that speaks to change in household consumption in the third quarter in 2019. 2. From the information in this article, did household consumption increase or decrease in the…

If there is a technological advance that leads to an increase in investment demand, then: A. investment increases and the interest rate rises. B. investment and the interest rate are both unchanged.

Nick and Steve both obey the two-period Fisher model of consumption. Nick earns $300 in the first period and $300 in the second period. Steve earns nothing in the first period and $620 in the second period. Both of them can borrow or lend at the interest rate r. Nick and Steve both consume $200 in the first period and $200 in the second period. What is the interest rate r?
What is the Euler equation for consumption, and what is its economicinterpretation?
QUESTION TWOConsider a hypothetical economy with the following model.Goods Market Money MarketC = 200 + 0.75(Y − T) (M/P)d = Y − 100rI = 200 − 25? Ms = 1000G = 100 P = 2T = 100A. Derive an expression for the IS curve and an expression for the LM curve. B. On the same set of axes, draw the IS and LM curve. C.

Economists in Funlandia, a closed economy, have collected the following information about the economy for a particular year: Y = 10,000; C = 6,000; T = 1,500; G = 1,700. The economists also estimate that the investment function is: I =3,300 –100r where r is the country’s real interest rate, expressed as a percentage. Calculate private saving, public saving, national saving, investment, and the equilibrium real interest rate
