Question 6 Unsaved Suppose a closed economy with no government spending or taxing initially. Suppose also that intended investment is equal to 150 and the aggregate consumption function is given by C = 250 + 0.75Y. And suppose that, if at full employment, the economy would produce an output and income of 3200 By how much would the government need to raise spending (G) to bring the economy to full employment?

14) You are evaluating a closed-end mutual fund and see that its price is different from its net asset value (NAV).

The fund has an expense ratio (ε) of 4.95% and a dividend yield (δ) of 4.00%. The fund has experienced a risk-adjusted abnormal return (α) of 6.05%.

a)By what amount (premium or discount) is the fund likely to trade relative to its NAV?

Use the equation: (α−ϵ) / (δ + ϵ − α)

NewCorp stock has a required return of 10.00% and is expected to pay a dividend of $3.25 next year. Investors expect a growth rate of 5.55% on the dividends for the foreseeable future.

b. What is the current fair price for the stock?

c. Suppose the stock is selling at this price, but then investors revise their expectations. The new expectation for the growth rate is 5.20%. If investors are rational, what will be the new price for NewCorp stock?

Q1. Solow Growth Model. Consider the production function for a closed economy ? =2 ∙ K^1/2(AN)^1/2
Assume that the savings rate s equals 20% and the depreciation rate ? equals 5%. Further, assume the growth rate of the labor force g_N is 3% and the growth rate of technological progress gA is 2% per year.

a. Find the steady-state values of (i) capital per effective worker, (ii) output per effective worker, (iii) the growth rate of output per effective worker, (iv) the growth rate of output per worker, and (v) the growth rate of output. (2.5 marks)

Now we modify the basic Solow growth model described above, by including government spending as follows. The government collects taxes T to finance its government spending G in every period. Government spending per worker is given by a constant g, where g= G/N. Workers consume a fraction of disposable income C= (1-s)(Y-T). Suppose that the government has a balanced budget. Also assume that A= 1 and the growth rates of technological progress and the labor force are zero, gA=0, gN= 0.

b. Write down the capital accumulation equation. With the help of a diagram, illustrate that there can be two steady-state values of capital per worker (k*=K*/N). Carefully label your diagram. (3.5 marks)

c. We can focus on the high k* and ignore the low k* because the low k* is an unstable steady state. What is the effect of an increase in g on k*? What are the effects of an increase in g on aggregate consumption C? Explain.

d. Now we modify the way we define government spending. Suppose that government spending G is proportional to aggregate output Y, where G= zY. That is, government spending is a fraction z of aggregate output Y. Are there two steady-state values of capital per worker? What are the effects of an increase in z on capital per worker k* and aggregate consumption C? Explain.

A closed piston-cylinder system undergoes a cycle:
​Process 1 to 2 is an expansion process where heat is added. The temperature remains constant.
Process 2 to 3 is a constant volume heat addition process.
​Process 3 to 4 is a compression process where heat is lost. The pressure remains constant.
​Process 4 to 1 is polytropic expansion, Pvⁿ​=constant with n=1.4 and it is adiabatic (Q=0).
​Assume air, ideal gas, with constant specific heats, k=1.4. R=.287kJ/kgK

​f.) Calculate the efficiency or coefficient of performance based on your answer to part e.

A pipe fitted with a closed valve connects two tanks. One tank contains a 5kg mixture of 62.5 percent CO2 and 37.5 percent O2 on a mole basis at 30C and 125kpa. The second tank contains 10kg of N2 at 15C and 200kPa. The valve in the pipe is opened and the gases are allowed to mix. During the mixing process 100kJ of heat enrgy is supplied to the combined tanks. Determine the final pressure and temperature of the mixture and the total volume of the mixture.

Let C be the closed path that travels from (0, 0) to (1, 1) along y = x^2 , then from (1, 1) to (0, 2) along y = 2 − x^ 2 , and finally in a straight line from (0, 2) to (0, 0). Evaluate Z C e ^3−x √ 3 − x ) dx + (5x − y √ y^2 + 2) dy

Consider the water-shift gas reaction:

H2O + CO --> H2 + CO2

A closed reaction vessel maintained at 3000 degrees Celcius is filled with 0.475 M H2 and 0.490 M CO2. At equilibrium, their respective concentrations are 0.410 and 0.425 M.

PART A:

The following ratio represents

[H2][CO2] / [H2O][CO]

CHOOSE ONE OR MORE:

the law of mass action, the mass action expression, the equilibrium constant expression, the equilibrium constant. none of these

PART B:

which way must the system shift in order to attain equilibrium

CHOOSE ONE

to the right, to the left, cannot be determined

PART C:

the value 41.0, represents

CHOOSE ONE OR MORE

the law of mass action, the mass action expression, the equilibrium constant expression, the equlibrium constant, none of these

PART D:

The equilibrium constant, Kc, is unitless, why?

CHOOSE ONE

in the expression for Kc, molarities are always used so units are redundant

the cncentrations in K are theoretically ratios of the concentrations to an ideal standard 1.000 M

the concentration units are ignored. K actually has units if there aren't equal numbers of M units in thenumerator and the denominator

In large steam power plants, the feedwater is frequently heated in closed feedwater heaters (basically heat exchangers) by steam extracted from the turbine at some stage. Steam enters the feedwater heater at 1.5 MPa and 250℃ and leaves as saturated liquid at the same pressure. Feed water enters the heater at 2.5 MPa and 60℃ and leaves at 10℃ below the exit temperature of the steam. Neglecting any heat losses from the outer surfaces of the heater, determine (a) the ratio of the mass flow rates of the extracted steam and the feedwater heater and (b) the total entropy change for this process per unit mass of the feedwater.

Question:

The economic shocks due to the current pandemic began with a supply-side contraction: businesses closed their doors and laid-off workers, leading to significant reductions in output and income. Use what means of analysis is at your disposal to explain what the consequences of such a shock are for financial and economic performance in the short run. Then consider the shock to be exacerbated by pessimism about the future, with government responses taking the form of debt-financed transfers. Explain some possible implications of this for financial market behavior during the recovery.
