Topic 8 Spending and Output in the Short Run

8.1 Explain the errors of the following arguments made by an economicsstudent:

a) “The textbook said that a higher interest rate lowers investment, but that doesn’t make sense. I know that if I can get a higher interest rate, I am certainly going to invest more in my savings account.”

b) “The newspaper said that the recent recession was caused by a decline in investment. This can’t be true. If there had just been a decline in investment, the only firms hurt would have been construction firms and other firms selling investment goods. In fact, many firms experienced falling sales during that recession, including department stores and firms selling consumer electronic products.”

8.2 Company A in country X is considering the investment in a project with the following (estimated) cost and benefit. The project has a life of 3 years and has zero value after the third year.

a) Suppose in year 0 Company A could borrow or lend at an annual interest rate of 4%. Explain clearly with calculation whether Company A will invest in this project.

b) Based on your answer in part (a) explain how an increase in interest rate to 5% will affect Company A’s investment decision.

c) There is a concern about the unemployment problem in country X and the lack of investment demand is regarded as one of the major reasons of unemployment. Suppose other firms in country X will be affected in the same way as Company A as described in part (a) and (b) above. Use the Keynesian model to explain the process of how a change in interest rate may help to solve the unemployment problem.

8.3 Consider the following Keynesian model: Consumption:

C = 200 + 0.7Yd

Lump-sum tax: T0 = 50

Proportional Tax Rate: t = 0.2

Government Expenditure: G = 435

Planned Investment: I = 300

Exports: X = 100

Imports: M = 0.06Y

Yd: Disposable Income

Numbers are in billion dollars.

a) Each row corresponds to one possible output level. Fill in the remaining columns of the table given the equations given above.

b) What is the equilibrium output level of this economy?

c) What is the level of unplanned investment at the output level of 1500 and at the level of 15 2500? If it is not in equilibrium, describe how the economy would adjust to the equilibrium in each case.

d) What is the change of equilibrium output when government expenditure increases to 560? Explain your steps. What kind of policy is it?

e) If investment decreased to 175 billion dollars under policy uncertainty, how does it change the equilibrium output level? Is the change in equilibrium output larger than the change in investment? Why?

f) What factors would affect the size of expenditure multiplier? Briefly explain

Smith's Inc, Inc., produces widgets for the wind chime industry. The company sells all products on accounts with net 30 day terms. The company has been without someone to assess the financial condition for some time (using only a bookkeeper to post activity to the general ledger accounts) and, therefore, is asking you to help with a more current assessment of the company’s position.

Part A: Below you will find a series of accounts that represent the trial balance of the business firm. These accounts encompass both income statement and balance sheet accounts.

2009   2010   2011

Accumulated depreciation 176,580 209,050 242,275

Retained earnings     337,602   510,731 648,528

Cash 35,750    62,635 86,595

Bonds payable 421,000 334,000   325,000

Accounts receivable   246,580   293,430   349,182

Depreciation expense 31,265 32,470 33,675

Common stock shares outstanding 80,000   80,000 80,000

Plant and equipment, at cost   984,021 1,026,880 1,151,210

Taxes 79,484   93,223   74,198

Accounts payable 62,685 116,696 188,569

Common stock, $1 par 75,000 75,000 75,000

Inventory   185,652 243,117 312,622

Prepaid expenses 6,575 21,525   26,325

Cost of goods sold 2,665,786   2,879,049   2,936,630

Interest expense 12,532 10,325 10,235

Selling and administrative expenses   765,800 773,458 788,927

Marketable securities 12,545 23,564 24,153

Other current liabilities   123,256   150,674   195,265

Capital paid in excess of par (common) 275,000 275,000   275,000

Part B: Based on the financial statements that were prepared with this data, complete the following financial ratio calculations and provide a narrative discussion of these results as compared to industry averages (provided.)

Ratios required:

Ratio Industry Average

1. Profit margin 3.2%

2. Return on assets (use ending assets) 6.0%

3. Return on common equity (use ending common equity) 15.6%

4. Receivable turnover (use ending receivables) 8.5 x

5. Inventory turnover (use ending inventory) 12.0 x

6.Fixed asset turnover (use ending fixed asset balance) 5.75 x

7. Total asset turnover (use ending assets) 1.89 x

8. Current ratio 3.10

9. Quick ratio 1.40

10. Debt to total assets (use ending assets) 37.0%

Your solution should include the required ratios for each year and then provide a narrative discussion regarding the results as they compare to the industry averages. This analysis should discuss whether or not Smith's Inc. is better or worse than the industry average but it should not stop there. You should also include a discussion as to why or how the difference can be explained, i.e., the reason for the variance. The final solution is to be provided in the Word document, with the module and part clearly identified. The narrative discussion will reference the appropriate ratio and the comparison to the appropriate industry average.

Smith's Inc.., produces wind chimes for the wind chime industry. The company sells all products on accounts with net 30 day terms. The company has been without someone to assess the financial condition and, therefore, is asking you to help.

Part A: Below you will find the trial balance of the business firm and need to be placed into the correct statement.

Required: Prepare a Income Statement and Balance Sheet for the company.

Part B: Based on the financial statements that were prepared with data above, complete the following financial ratio calculations and provide a narrative discussion of these results as compared to industry averages (provided.)

explain how the banking system 'creates' money independent from the amount of currency in the economy. In your own words indicate whether this is a major or minor source of money in the economy and whether you think it compares today vs 20 years ago vs how important it might be 20 years in the future. (Is the role of the banking system consistent over time or evolving? If evolving where is it heading, if its not evolving, why has it remained stable over time?)

While we are still far from “Transcendence” -style artificial intelligence — like uploading human consciousness to software programs, at the rate we are going in technological innovations and in terms of the convergence between our noted three worlds ( the physical world, the virtual or digital world, and our very own intellectual world “inside our brain”), we could someday digitize the human brain, and reproduce cognitive intelligence and emotions, machines and computers that can totally replace human insight.

What are the pros and cons of this technological evolution and what kind of implications would this have on an individual and our society as whole?

1. Consider Consumers A, B, and C with the following preferences over two goods.

U_A (x₁,x₂) = x₁²x₂³

U_B (x₁,x₂) = 2x₁+3x₂

U_C (x₁,x₂) = min{2x₁,3x₂)

The prices given are p1, p2 and income for each consumer is m.

Solve for the Engel curves for each consumer.

please be very detailed, thank you!

Consider two solutions, the first being 50.0 mL of 1.00 M CuSO4 and the second 50.0 mL of 2.00 M KOH . When the two solutions are mixed in a constant-pressure calorimeter, a precipitate forms and the temperature of the mixture rises from 21.5 ∘C to 27.7 ∘C .

From the calorimetric data, calculate ΔH for the reaction that occurs on mixing. Assume that the calorimeter absorbs only a negligible quantity of heat, that the total volume of the solution is 100.0 mL , and that the specific heat and density of the solution after mixing are the same as that of pure water.

1. Add the function int getNodeLevel (T value) to the Binary Search Tree class provided below. The function should return the level of the node value in the Binary Search Tree.

Hint:

Set currentNode to root

Initialize level = 0

while currentNode != Null

         if currentNode element = value return level

         else move to either the right child or the left child of the currentNode, update the loop, and repeat the loop

Function should return -1 if value is not in the tree
