A series of 10 end-of-year deposits is made that begins with $6,500 at the end of year 1 and decreases at the rate of $300 per year with 8% interest.

a. What amount could be withdrawn at t = 10?

b. What uniform annual series of deposits (n = 10) would result in the same accumulated balance at the end of year 10?

I would like to be able to use excel functions to solve this rather than by hand. Thanks!

(a) Outline and explain in detail four types of market failure. What types of problems do market failures give rise to in the economy? Please give an example for each of the market failures you have outlined. Diagrams are not required in this question. 30 marks

(b) Does market failure automatically mean that the government should intervene to deal with the problem? Explain your answer. This question refers to market failure as a whole and not to a particular type of market failure.10 marks

1. Consider the Solow model of economic growth, with no technological progress. Assume that δ=0.07 and n=0.03. The production function is given by Y=K^0.5 L^0.5. The savings rate s=0.5.
   

a) Calculate the steady state levels of capital per worker, output per worker and consumption per worker.

b) Now, suppose there is an exogenous change in n, which increases to n=0.055 (while δ, s and the production function remain identical). What are the new steady state levels of capital per worker, output per worker and consumption per worker?

c) Use the Solow diagram to depict the effects of the change in n on steady-state capital per worker

d) After the change in n, is it possible for the economy to go back to the level of steady-state consumption per worker that it had before the change in n by changing its savings rate?

• How does the US tax system foster inequality and effect the economy and market structures? Do you agree or disagree with the need to change the tax system? Do you think changing the tax system is possible in the current political economy? How will the tax bills which passed recently by the Senate and Congress effect your taxes? How will the effect inequality? What are your suggestions?

1. Consider the aggregate demand/aggregate supply model of Chapter 10. Assume that the long-run aggregate supply curve is vertical at Y = 3,000 while the short-run aggregate supply curve is horizontal at P = 2. The aggregate demand curve is given by Y = MV(1/P), with M = 6,000 and V=1.
   

a) Suppose that there is an adverse supply shock that shifts the short-run supply curve upwards, to P = 3. What are the values of P and Y in the short-run equilibrium after this shock?

b) What changes (if any) in the values of P and Y would take place going from the short-run equilibrium of part A to the long run (assuming no other shocks occur)?

c) If the FED wants to avoid any changes in the level of Y as a response to the supply shock, what should be the change in the quantity of money M?

A company decided to choose between two projects based on the shorter discounted payback period at an interest rate of i=10%. Both projects will have a service life of 6 years. Project A needs an initial investment of $20,000 and will generate a net cash flow in years 1 through 6 of $6,500. Project B needs $17,500 to invest initially, and will have a variable net cash flow as follows: $1,500 in year 1, $3,000 in year 2, $4,500 in year 3, $5,000 in year 4, and $7,000 each in years 5 and 6.Which project will the company choose and what is its discounted payback period?

1. Firm A and Firm B make identical products. Industry demand is Q = 90 - P. Both firms have a constant marginal cost of $30. There are no capacity constraints. a) Solve for the equilibrium price and quantity produced under Bertrand-Price model of competition. How much profits would they make? ii) Cournot-Quantity model of competition. How much profits would they make? b) Suppose that firm A is considering whether to invest in research and development that would lower its marginal cost to $15. How much would firm A be willing to pay for this research assuming 1) Cournot-Quantity model of competition 11) Bertrand-Price model of competition. Hint: solve for the equilibrium when A has a MC =15$ and B has a MC of $30 and compare the profits that you have found in part a) where they both had MC of $30 c) Now assume that Firm A has a capacity constraint of 30 units of production and Firm B has a capacity constraint of 20 units. In a Bertrand-Price competition model would the Bertrand - paradox hold? What would be the equilibrium price? How much profits would the firms earn?

Suppose that output Q is produced with the production function Q = f(K,L), where K is the number of machines used, and L the number of workers used. Assuming that the price of output p and the wage w and rental rate of capital r are all constant, what would the profit maximizing rules be for the hiring of L and K?
(b) What is the MRTSK,L for the following production function: Q = 10K4L2? Is this technology CRS, IRS or DRS? How do you know?
(c) If the production function was Q = 4KL1/2, what are the conditional demand functions for K and L? Find the cost function C(w,r,Q) for the production function in part (a). Show 3 general properties of cost functions hold for this cost function. (d) Suppose you know the cost function is C(w,r,Q) = 2wQ + rQ 2 . Can you determine the returns-to-scale of the technology? If so, what is it?

What explains the expansion of government in the post-World War II period and elaborate on the roles that governments perform in the economy.

You are asked to make your own list of the best places to live (it can be one, two, or more) and convince your reader to move there. Build your case by using as many economic indicators you think of How important would the country's per capita real GDP be as a criterion? What other factors in your own view would you consider?
