Assuming a closed economy A, where I= 22-3r and S= r+ 14, then the cost of one unit of future consumption in a country A equals how many unit of current consumption.
Equating I and S,
22 - 3r = r + 14
4r = 8
r = 2%
Cost of 1 unit of future consumption = 1 x (1.02) = 1.02 units of current consumption

Refer to Figure 14-1. Suppose the economy is operating at point m on curve A. The decision to move to point p I. requires a sacrifice of current consumption. II. requires a sacrifice of future consumption. III. adds to the economy’s capital stock assuming depreciation remains at a level corresponding to point m. IV. enables the economy to increase both its consumption and investment in the future. Select one: a. I and II only b. I and III only c....
The demand for vans in a certain country is given by: D = 12 300 − 240P where P is the price of a van. Supply by domestic van producers is: S = 6700 + 60P. a) Assuming that the economy is closed, find the equilibrium price and production of vans. b) The economy opens to trade. The world price of vans is 20 units. Find the domestic quantities demanded and supplied, and the quantity of imports or exports. Who...
The income identity for a closed economy says that Y-C+I+G Assume that in the Economy of Berkeley GDP (Y) is equal to 6,000 and consumption (C) is given by the equation C 600+0.6(Y - T). In addition, investment (I) is given by the equation 1 2, 000-100r where r is the real of interest rate in percent. Taxes (T) are 500 and government spending (G) is also 500. What are the equilibrium values of C, I, and r?

worth 9 points The income identity for a closed economy says that Y-C+I+G Assume that in the Economy of Berkeley GDP (Y) is equal to 6,000 and consumption (C) is given by the equation C-600+0.6(Y - T). In addition, investment (I) is given by the equation I-2,000 100r where r is the real of interest rate in percent. Taxes (T) are 500 and government spending (G) is also 500. What are the equilibrium values of C, I, and r?
2. The country, Hoosier (a closed economy), has the following data: GDP: Y = 1200, Consumption: C = 600 – 10,000 r, Taxes: T = 200, Government purchases: G = 300. The investment is I = 700 – 10,000 r a. Use the information above to find the supply and demand equations for loanable funds: i. Supply equation: ii. Demand equation: _ b. What is the equilibrium interest rate, r, and what are national saving and investment, S and I?...
