Question 1. One period macroeconomic model
We consider an economy closed to a period populated by consumers and produce. The representative consumer chooses the quantity of leisure, let of consumption, as its utility under budget constraint. The representative producer chooses the labor factor that maximizes his profile Preferences satisfy the same properties as in the standard consumer model Similarly, the production function, Y = F(K.N), where k is the capital stock and the quantum labor factor obeys the properties than those of the standard model: in particular, the marginal product of labor is strictly decreasing compared to Net strictly increasing compared to K. Moreover, F(0,N) = F(K,0) = 0. Consumers and producers exchange labor for the consumer good in the labor market; consumers own the businesses and receive all of the profits. It is assumed that the government does not intervene and that public expenditure is zero.

1)Within the framework of this macroeconomic model, define a competitive equilibrium.
2) From the definition of a competitive equilibrium, construct the frontier of production possibilities associated with the choice between leisure and consumption. Explain your approach Graphically represent the quantity of consumption and leisure at equilibrium
3) What is the effect of a fall in the stock of capital, K?Using a graph, Mustrize the effect of this change on the competitive equilibrium. Interpret the result by explaining the mechanism at work

A closed rigid cylindrical vessel (internal diameter = 2 ft and internal height = 10 ft) has R-134a at x = 0.95 and 40 oF. The vessel is heated up to 100 oF. Assume that heat loss from the vessel is negligible. Kinetic and potential effects are negligible. Determine 1) the final pressure in psi [lbf/in2], 2) the mass of R-134a in lbm, 3) the heat transfer in Btu for this process and discuss its direction (if the heat is added to or rejected from the system), 4) the work transfer in Btu for this process and discuss its direction (if the work is done by or on the system), and 5) draw the process in T-v (temperature-specific volume) diagram.

A closed-end fund starts the year with a net asset value of $30. By year-end, NAV equals $31.90. At the beginning of the year, the fund is selling at a 2% premium to NAV. By the end of the year, the fund is selling at a 7% discount to NAV. The fund paid year-end distributions of income and capital gains of $3.30. a. What is the rate of return to an investor in the fund during the year? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Rate of return % b. What would have been the rate of return to an investor who held the same securities as the fund manager during the year? (Round your answer to 2 decimal places.) Rate of return %

Consider a closed economy where firms fear that sales will soon decline and therefore reduce investment (demand shock), although they are not currently facing lower than usual sales and there have been no changes in the interest rate.

A) Use the linear specification of the IS-LM model and its graphical representation to explain what is the effect of the demand shock on the equilibrium level of output assuming that the central bank does not change the monetary policy following the shock.

B) How would your answer change assuming, instead, that the central bank takes monetary policy decisions to avoid changes in the level of output following the shock?

9.5 A closed economy is described as follows:

C^d = 70 + .6(Y-T) - 300r                I^d = 100 - 500r

L = .2Y - 250i     p^e = 0%       G = 40     _      T = 50

M = 120                          NFP = 0         Y = 210

(a) What will the interest rate be in the long run? SHOW YOUR WORK.
(b) What will the price level be in the long run? SHOW YOUR WORK.
(c) Given an equation for the AD curve for this economy in the form Y = …………. (The answer will not have round, pretty numbers. But, if you have time, you can double check your answer to verify that it is the correct equation another way.)

Suppose a closed economy has a consumption-output ratio of 0.8. Total output is 1 Billion in 2018 and the capital stock equals 5 Billion. It's depreciation rate and population growth rate are both equal to 2%. What is true in 2019?

income will have grown

consumption will take an even larger share of output

we do not have enough information to calculate changes from 2018 to 2019

the capital stock must be smaller than in 2018

How can I re-write the following questions as closed-ended questions to be included in a questionnaire?

1. Do agree that the World Bank were able to measure the degree to which loan conditions were implemented in Emerging Markets when political influences favored policy reforms during the fall-out of the 2008 Global Economic Crisis.

2. In response to the 2008 Global Economic Crisis, do agree that the World bank efficiently reduced poverty by increasing lending in larger degrees to middle income countries and lowered lending to low income countries? THANKS.

One year ago, Super Star Closed-End Fund had a NAV of $10.23 and was selling at a(n) 15% discount. Today, its NAV is $11.72 and it is priced at a(n) 6% premium. During the year, Super Star paid dividends of $0.4 and had a capital gains distribution of $0.93. On the basis of the above information, calculate each of the following

a. Super Star's NAV-based holding period return for the year.

b. Super Star's market-based holding period return for the year. Did the market premium/discount hurt or add vlaue to the investor's return? Explain.

c. Repeat the market-basede holding period return calculation, except this time assume the fund started the year at a(n) 14% premium and ended it at a(n) 6% discount. (Assume the beginning and ending NAVs remain at $10.23 and $11.72, respectively.) Is there any changes in this measure of return? Why?

a. Super Star's NAV-based holding period return for the year____%

3. Use oil-tempered 0.060” diameter wire to make a spring with squared and closed ends, a
spring index of 4, and solid length of 1.25”. Use a load factor of safety of 1.05 and make the free
length 1.75 inches.

e) What is the force to close to solid, Fs?
f) What is the critical frequency?
g) What is the factor of safety, solid, ns?

Given the following data for a hypothetical closed economy:

1. Fill-in the table.

2. Determine the Breakeven for the economy.

3. Determine the equilibrium GDP for the economy.

4. Calculate the expenditure multiplier.

5. Now suppose that the potential GDP equals 440, by how much should the government purchases or tax change to reach the potential GDP.

6. Drive consumption or saving equations. (show your work)
