(a) Consider a closed economy whose desired savings (Sd) and desired investment (I) are given by the following expressions: where r denotes the real interest rate. Find the equilibrium in the Goods market for this economy, and represent it in a graph. From now on, suppose there are two large Countries in the world, say Canada (Ca) and the United States (US). Sd 100+600r Id = 170-400r (b) To start with, assume that both Countries are closed economies. Their desired consumption (Cd) and desired investment (I) are given by: Coca = 10+ cca (Yca - Tca) - 100r 15 - 100r IC CUS IUS = 40+ cus (Yus - Tus) - 200r = 230 - 200r Moreover, output (Y), taxes (T), public expenditure (G), and the marginal propensity to consume (c) are as follows:

Consider a competitive, closed economy with a Cobb-Douglas production function with parameter α = 0.25. The parameter A is equal to 60. Assume also that capital is 100, labor is 100. Assume that in this economy consumption (C) is given by the equation C = 600 + 0.6(Y – T). Investment (I) is given by the equation I = 2,000 – 100r, where r is the real rate of interest in percent. Taxes (T) are 500 and government spending (G) is also 500. (Hint: use the GDP obtained in part a). What are the equilibrium values of C, I, and r? What are the values of private saving, public saving, and national saving?
Consider an H-O economy in which there are two countries (US and France), two goods (wine and cheese) and two factors (capital and labor). In each question below you are given partial information about the model and asked to infer some other part. Treat each question separately and independently. 1. Suppose a decrease in the price of cheese causes a decrease in the wage rate in the US economy. Which factor is used intensively in cheese production in France? Which H-O theorem is used to get this answer? Explain. 2. Suppose France exports wine, the capital-intensive good. Which factor benefits from free trade in the US? Explain. 3. Suppose workers in France benefit when tariffs are increased on cheese imports. Which factor is used intensively in cheese production? What is France's abundant factor? Explain.
How does investment as defined by economists differ from investment as defifined by the general public? What would happen to the amount of investment made today if firms expected the future returns to such investment to be very low? What if firms expected future returns to be very high?
True or False: It is possible, in a basic hours towards leisure and income towards consumption model, that the Earned Income Tax Credit can encourage more hours towards leisure, less hours towards work and more money towards consumption.
Describe (in symbols) the datum and variables of the economy. Express the definition of the Walrasian equilibrium for this economy using vector notation.
Only typed answer Which of the following is true in the circular flow model of the economy? a. Households are demanders in the output market and demanders in the input market. b. Firms are demanders in the output market and demanders in the input market. c. Households are demanders in the output market and suppliers in the input market. d. Households are suppliers in the output market, and firms are suppliers in the input market. Firms are
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%…
Refer to the macroeconomic example, use Cramer's rule to compute Y* AND I*. The equilibrium values of Y and I evaluated at M₀=300, G₀=500, a=100, α=200, b=0.8, t=0.5, β=1, γ=0.4, and δ=1 are Y* =?, I*=?
The following are exogenous (not directly affected by income): G = 9 I = 14 X = M = 0 The consumption function is: C = k + cY, where k = 8, c = 0.6 at the point where this economy is in equilibrium what is the total level of withdrawals? Give the number to ONE decimal place.
Using a graph and words, explain the effect of SRAS and LRAS curves when the President of the United States would give businesses who invested in new plant and equipment an investment tax credit equal to 10 percent of their investment and the marginal tax rate has been reduced to people who make over $50,000 and are permanent. Will you work more or less when marginal tax rates are cut and will businesses invest more in plant and equipment when an investment tax credit has been implemented by the President of the United States? Also explain in your graph what will happen to equilibrium price level and equilibrium real GDP and the unemployment rate when the marginal tax rates are cut and are permanent for people making over $50,000 and the investment tax credit has been implemented by the President of the United States.
Consider an economy where: Zt = c0 + c1Y1 + It Yt = Zt-1 Let c0 = 100, c1 = 0.75, and assume that the goods market is initially in equilibrium with Ẑ = Ŷ = 1200, and Î = 200. Suppose that in period t0 investment undergoes a permanent increase from 200 to 300. Find values for Yt and Zt in periods t0 + 1, t0 + 2, and t0 + 3. What are the final values for Y and Z? Please show all calculations, thanks!
Using the ZZ(The line ZZ represents the demand for domestic goods (including exports) and NX graphs, illustrate graphically and explain what effect a reduction in foreign output (Y*) will have on output, exports, imports, and net exports.
