IS-LM Model (Closed Economy)
The following equations describe a small open economy.
[Figures are in millions of dollars; interest rate (i) is in percent]. Assume that the price level is fixed.
Goods Market
C = 250 + 0.8YD
YD = Y + TR – T
T = 100 + 0.25Y
I = 300 – 50i
G = 350; TR = 150
Money Market
L = 0.25Y – 62.5i
Ms/P = 250
Goods market equilibrium condition: Y = C + I + G + X-M
Money market equilibrium condition: L = Ms/P

b) What is the equation describing the LM curve (YLM)?
c) What are the equilibrium levels of income (Yo) and interest rate (io)

Suppose the U.S. has a closed economy with GDP (Y) equal to $20.3 trillion, consumption (C) equal to $12.0 trillion, government spending (G) equal to $3.9 trillion, transfer payments (TR) equal to $1.8 trillion, and taxes (T) equal to $4.2 trillion.
Suppose the government passes legislation to reduce the size of its debt by reducing government spending by $0.4 trillion. What must happen to total savings (S)? That is, what is the dollar amount by which total savings changes? Assume the values for GDP, consumption, taxes, and transfer payments do not change. Provide your answer in trillions of dollars rounded to one decimal place. Use a negative sign "-" for negative changes. Do not include any symbols, such as "$," "=," "%," or "," in your answer.

A five-sided closed field traverse has the following distances in meters: AB = 51.766; BC = 26.947; CD = 37.070; DE = 35.292; EA = 19.192. The adjusted angles are as follows: A = 101°03′19″; B = 101°41′49″; C = 102°22′03″; D = 115°57′20″; E = 118°55′29″. The bearing of AB is N 73°00′00″ E. BC is in the S.E. quadrant.The coordinates of the five(5) corners of the traverse have been computed to be as follows: Corner "A" X Coordinate 1000.000 Y Coordinate 1000.000 Corner "B" X Coordinate 1050.019 Y Coordinate 1013.314 Corner "C" X Coordinate 1062.085 Y Coordinate 989.218 Corner "D" X Coordinate 1033.262 Y Coordinate 965.900 Corner "E" X Coordinate 1001.292 Y Coordinate 980.852 The area of the traverse using the coordinate method is 1,857 Square meters. If you used the area computation method we used in class and on the homeworks, the computed number using coordinate method for area computation for corner "C" is_______? Your answer will be in square meters to four (4) decimal place accuracy. |

11) The wave function of a many-electron closed-shell atom can be expressed as a Slater determinant. A useful property of determinants is that interchanging any two rows or columns changes their sign and therefore that if any two rows or columns are identical, then the determinant vanishes.
Use this property to show that (a) no two electrons can occupy the same orbital with the same spin.

7. Consider the following income-expenditure model of a closed economy. The aggregate consumption function is C = 100 +0.8(Y – T); taxes are T = 380; investment, I, is 300 and government expenditure, G, is 200.
(a) Calculate the multiplier, equilibrium income and the government budget surplus [6 marks]
(b) Now let taxes, T = 10 + 0.25Y. Recalculate the multiplier, equilibrium income and the government budget surplus. Try to explain any differences between your answers and your answers to part (a). [10 marks]
(c) Now we further extend the model and open the economy to trade. Let net exports be NX = 444 - 0.3Y. Keep the tax function as in (b). Recalculate the multiplier and equilibrium income and again explain any differences between your answers and those in part (b).

One year ago, the Tyler Rose closed-end fund had a NAV of $35.19 and was selling at an 11% discount. Today, the fund has a NAV of $36.42 and is selling at a 7.5% premium. During the year, the fund paid a dividend distribution of $.48 and a capital gain distribution of $.97.
A. Calculate the NAV-based HPR for the fund for the year.
B. Calculate the market-based HPR for the fund for the year.
C. Recalculate the market-based HPR for the fund for the year, assuming the fund was selling at an 8.8% premium at the beginning of the year and an 11.3% discount at the end of the year.

A closed container at 58.1˚C and 285 mm Hg contains a mixture of n-heptane and cyclohexane. Both liquid and vapor phases exist in equilibrium, and the vapor phase contains 32 mol % n-heptane. a) Calculate the mole fractions of the liquid phases. b) Now, the pressure in the container doubles, will the saturation pressure of n-heptane increase, decrease, or stay the same?

Problem 3.034
A closed, rigid tank is filled with water. Initially, the tank
holds 0.4 lb of saturated vapor and 4.0 lb of saturated liquid,
each at 212°F. The water is heated until the tank contains only
saturated vapor. Kinetic and potential energy effects can be
ignored.
Determine the volume of the tank, in ft3, the
temperature at the final state, in °F, and the heat transfer, in
Btu.

Consider two long wire with negligible resistance closed at one end of the resistance R (say a light bulb), and the other end connected to a battery (DC voltage). Cross-sectional radius of each wire is in x=100 times smaller than the distance between the axes of the wires.
Question:
At which value of resistance R (in ohms) the resultant force of the interaction of parallel conductors disappears?

5. You have been asked to appraise a closed Burger King on Hwy. 1 in Virginia Commons. The building was built 5 years ago, but has been vacant for the last 2. Vacant buildings tend to deteriorate faster than occupied buildings. For this reason you estimate the age of the building at 9 years. Fast food restaurants have an expected economic life of 20 years. The building is 2,100 square feet and sits on a lot that is 4,200 square feet. A lot just south of the subject sold recently for $18.50 a square foot. Fast food restaurant construction costs average $210 per square foot. What is your estimate of the value of this property (hint – cost approach)?
