Suppose that a new free trade agreement allows the economy to import cheaper goods from overseas, thereby decreasing the general price level. Adjust the following graph by either shifting the consumption function curve or the initial point on the consumption function curve (A) to illustrate the impact of a fall in the price level.

1a) and b)

The figure below shows the average share of total household expenses for a good and the inflation-adjusted price of the same good. The share of all expenses line is calculated as expenditures on this good (that is the price of this good multiplied by the quantity of this good purchased) divided by total household expenses. This line shows how expenditures on this good changes over time, holding total spending constant. The other line is the price of this good adjusted for inflation (i.e., the increase in the price level for all goods). The specific units are obscured on purpose.  Use these data to characterize the price elasticity of demand. Explain using the definitions of price elasticity of demand and total expenditure. Notice that I am not asking you to calculate the price elasticity of demand. Use the data to talk about the size of price elasticity of demand in general terms. Is demand elastic or inelastic? Is the price elasticity of demand very large? Very small? Close to 1?…

Consider a closed economy that is characterized by the following equations: Y = C +1+ G (1) C = 500 + 0.75(Y-T) (2) | = 375-25r (3) T = 500 (4) G = 500 (5) m = m, (6) m. = 1000 (7) m, = 0.5Y (8) m, = -50r (9) Where Y is the GDP, C is private consumption expenditure, I is the Investment expenditure, G is government expenditure, T is tax revenues, M̟ is money supply, M, is transaction demand for money. M, is the speculative demand for money and r is the interest rate (in % points). a) Derive (m/P) the demand for real money balances equation (where P is the aggregate price level.) b) Derive the IS and LM equations of the economy (Express Y as a function of r and assume Pis fixed at 1.0.) c) Calculate the short-run equilibrium values of Y and r in the economy.

Suppose that M = 2000 and that k = 2. What is the price level P at which the economy is in long-run- equilibrium? Plot such an equilibrium on a diagram with P on the vertical axis and Y on the horizontal axis, by distinguishing between the short-run and the long-run equilibrium.

1. What is a market-clearing model? When is it appropriate to assume that market clear? 2. Use the model of supply and demand to explain how fall in the price of frozen yogurt would affect the price of ice cream and the quantity of ice cream sold. In your explanation, identify the exogenous and endogenous variables. 3. Consider an economy that produces and consumes hot dogs and hamburgers. In the following table are data for two different years. Goods Hot dogs Hamburgers Quantity (2010) 200 200 Price (2010) $2 $3 Quantity (2020) 250 250 Price (2020) $4 $4 Using 2010 data as the base year Compute the following statistics for each year. Nominal GDP, Real GDP, GDP Deflator, Inflation rate using GDP deflator, CPI, Inflation rate using CPI. (Hint: i) to calculate CPI use base year fixed quantity Hot dogs 200 and Hamburgers 200, ii) To calculate inflation rate, use percentage change in price level between two years.)

Suppose Bank of England is considering using the tool of cutting interest rates to boost household consumption. In this question you will be asked to use the intertemporal choice model to assess the impact of different policies on household consumption. Suppose a consumer's current income is £25,000 and their future income is £30,000, and they initially face a market interest rate of 15% on both saving and borrowing. (a) In a diagram with consumption this year (C1) on the horizontal axis and consumption next year (C2) on the vertical axis, illustrate this consumer's budget constraint (using the numerical values set above) and indicate their optimal choice by drawing a indifference curve convex to the origin, assuming that at the current interest rate it is optimal for them to save. (b) Calculate (using the numerical values set above) and interpret their marginal rate of time preference at their optimal choice. (c) Illustrate and explain how a fall in the market interest rate from 15%…

1. Which of the following equations is the correct expression of the IS curve? ao+Bo-B₁i+G a. Y = b. Y= C. d. Y= 1-α₁ (1-t) C+I+G Y = 1-a₁ (1-1) ao+Bo-B₁i+G 1+α₁ (1-t) C+I+G 1+a₁ (1-1)

The table below shows the parameters for the economy of Hutu. Give your answers to one decimal point. XN = 160 0.15Y G = 220 C = 40 + 0.65Y I = 150 a. The value of equilibrium income is $ b. If exports were to increase by 40, the new value of equilibrium income would be $ c. Given your answer in part (b), the new value for XN is $ d. Given the equilibrium income in part (a), if full employment income is $800, what change in government spending is necessary to move the economy to this level? Government spending needs to decrease by $. A
