Two firms, A and B, sell widgets to a market of 100 buyers. The firms' widgets are undifferentiated, and the firms know each others' costs and capacities. Furthermore the firms are playing a one-time pricing game; widgets are obsolete after this one selling opportunity. Each buyer is interested in purchasing a single widget, and has an RP of $10.

Firm A has lower costs than Firm B, but also has lower capacity. Specifically, their (constant) marginal costs and capacities are as follows.

   Finally, assume that each firm can only post prices in whole dollar amounts. (This question is motivated by firms selling through coin-operated vending machines. It is too costly to stock such machines with pennies, so sellers must set prices in fixed increments of larger denomination coins.) Throughout this entire problem, firms may only choose prices of $1.00, $2.00, $3.00, ..., up to $10.00. Firms may NOT use prices such as $1.50, $2.99, $3.83, etc.

(2a.) Find equilibrium prices for this one-time pricing game. (As usual: all buyers go to the firm with the lowest price. However if Firm A's price is no higher than Firm B's price, Firm A serves only 30 buyers, and the rest go to Firm B. Your answer should be a pair of prices, one for each firm.)

(2b.) Suppose that before the pricing game starts, Firm A can build a production plant that would have full capacity of 100 units. (Marginal costs would remain the same, and Firm B would see Firm A's new capacity. Then firms would simultaneously set some equilibrium prices.)

Ignoring the cost of building, how much profit would Firm A earn if it expanded?  Firm A would now earn profits of ______________. (You must show your calculations for credit. The same assumptions apply as the previous part, except now the firms split the market 50/50 if they price equally.)

Classify the following transactions (current account transaction, financial account transaction), the sign of entry (plus or minus/ debit or credit). Choose one country of reference.

a) Walmart issues a corporate bond in the UK

b) A German tourist rents a car in Iceland

c) A U.S. worker in Canada wires money back to his family in the U.S.

d) A French company builds a plant in South Africa

e) Toyota exports cars to Spain.

Describe what happens when you try to push a heavy box (> 200lbs) that has been sitting on the floor for some time a) before it starts to move b) right after it starts to move c) if it acquired an acceleration without you pushing it harder, explain why in details using static and kinetic forces of frictions and 2nd Newton

It takes two materials to produce our widgets, Material X and Material Y. All of Material X is added at the beginning of processing, and all of Material Y is added at the 30% point in processing. At the beginning of March, there were 8000 units in Work in Process, 20% complete as to processing (Conversion). During March, there were 30000 units started into the process. At the end of March, there were 5000 units in Work in Process, 70% complete as to processing, Our Company uses the FIFO method of process costing. Prepare an equivalent units chart for the month of March

In April, we started 40000 units and completed 39000 units. The ending Work in process for April was 10% complete as to processing. Prepare an equivalent units chart for April.

Problem 10-4A Sell or process LO A1

Harold Manufacturing produces denim clothing. This year, it produced 5,120 denim jackets at a manufacturing cost of $42.00 each. These jackets were damaged in the warehouse during storage. Management investigated the matter and identified three alternatives for these jackets.

1. Jackets can be sold to a secondhand clothing shop for $8.00 each.
2. Jackets can be disassembled at a cost of $31,300 and sold to a recycler for $11.00 each.
3. Jackets can be reworked and turned into good jackets. However, with the damage, management estimates it will be able to assemble the good parts of the 5,120 jackets into only 2,980 jackets. The remaining pieces of fabric will be discarded. The cost of reworking the jackets will be $101,800, but the jackets can then be sold for their regular price of $45.00 each.

Required:
1. Calculate the incremental income.

For this discussion you will need to select a product, good, or service that you purchase on a regular basis. This could be anything from your morning coffee to the make of your car to your favorite chain restaurant. Conduct some formal research on the marketing strategy of the company or brand before you start your posts.

For Discussion

• Name of product and company: Use the proper corporate name, not a nickname.. Include pictures if you’re handy with uploading/inserting images.
• Product description: Briefly describe the product you’ve selected along with any relevant history that led you to choose this product/brand.
• Describe the key marketing strategies of your selected product. You should base your evaluation and report on what you can observe about how the four Ps are applied to the product you chose.
  • Product: Describe the want or need your product addresses.
  • Placement: Describe the physical location of the product among its closest competitors (a quick picture of the shelf would tell a good story!), and describe what this placement says about the marketing strategy.
  • Pricing: Describe the pricing strategy. A good description would include observations about the closest competitive product and its relative pricing.
  • Promotion: Describe how the product is being promoted. You could include any obvious physical/in-store promotions seen on the shelf, as well as flyers, coupons, social media, online advertising, etc.
  • Other factors: You might notice other important factors about your product that lie outside the four Ps. You can include them in your report here. One example might be a unique distribution system for your product.

Homework Assignment #1 ECO 3203, Spring 2020

Instructions: Answer each of the following questions. Show your work wherever possible, and justify your responses wherever appropriate.

Due: Friday, January 31st at the beginning of class


1. What is meant by the “marginal product of labor”? What typically happens to a firm’s marginal product of labor as it increases labor employment, all else equal? Why is that? What typically happens to a firm’s marginal product of labor as it increases capital employment, all else equal? Why is that?


2. Consider the following production functions:

 Y = AK1/2L1/2  Y = AK + 3L

a. Fixing total factor productivity (A) at 2 and labor employment (L) at 16 units, what is the marginal product of capital when capital employment (K) is 25, 35, and 45 for each production function? Do these production functions exhibit diminishing returns to capital employment? Explain. b. Are labor and capital complements under these production functions? Explain. c. Is either production function a “Cobb-Douglas” function? Explain.


3. Describe the difference between what the “nominal” wage rate and the “real” wage rate measure. How is a nominal wage rate converted into its real equivalent?


4. Consider a perfectly competitive, profit-maximizing firm facing the following marginal product of labor function and prices:

 MPL = 0.5A(K/L)1/2  W = 40  R = 60  P = 8  K = 4

a. What is the real wage rate paid by this firm?
b. If total factor productivity (A) is 20, how much labor (L) would this firm want to employ? c. If the price of output (P) rises from $8/unit to $10/unit, what will the new real wage rate be? All else equal, how much labor would the firm want to employ at that wage rate? d. Assuming that total factor productivity is 20, graph this firm’s labor demand function (quantity of labor demanded graphed against the real wage paid for labor) for values of the real wage between 4 and 40. Be sure to plot at least 3 distinct points.


5. Describe the difference between the “endogenous” and the “exogenous” variables of an economic model. In the classical model of a closed economy (Mankiw, chapter 3), which variables are endogenous and which are exogenous? List at least 4 variables in each category.


6. Use the classical model of factor markets (Mankiw, chapter 3) to predict how each of the following shocks should affect a nation’s real wages (W/P) and real rental price of capital (R/P). Be sure in each case to clearly state your predicted direction of change (up, down, or no change) for both variables and to depict your predictions with supply/demand diagrams for both the labor and capital markets.

a. The supply of capital (KS) decreases b. Technological innovation increases total factor productivity (A) c. Government purchases (G) are increased


7. How do macroeconomists typically define the difference between the “short run” and the “long run”? Is the classical model of a closed economy (Mankiw, chapter 3) considered a short run model or a long run model? Why?


8. Use the classical model of a closed economy to predict how each of the following shocks should affect a nation’s real aggregate income (Y), national saving (S), investment (I), and interest rate (r). Be sure in each case to clearly state your predicted direction of change (up, down, or no change) for all four variables and illustrate your predictions for S, I and r with a supply/demand diagram for the loanable funds market.

a. The supply of capital (KS) decreases b. Technological innovation increases total factor productivity (A) c. Government purchases (G) are increased d. Autonomous investment (i0) decreases

9. According to the classical model of a closed economy, what determines the size of a nation’s real aggregate income? Based on that theory, what kind of public policies could be used to increase a nation’s income? Give at least two specific examples.


10. Consider the following model of a closed economy:

 YS = AK1/2L1/2  Yd = C + I + G  C = 300 + 0.70(Y – T)  I = 2000 – 10,000r  W/P = MPL  R/P = MPK  KS = 100  LS = 225  A = 30  G = 1,000  T = 1,500

a. What are the market-clearing values of the real wage (W/P) and real rental price of capital (R/P) for this economy? b. Assuming that both factor markets clear, labor market and capital market clear, what will real aggregate income (Y) and national saving (S) be for this economy? c. What must the real interest rate (r) be in order to establish equilibrium in the market for loanable funds? d. What would the new equilibrium values of W/P, R/P, Y, S and r be if the capital supply (KS) increased from 100 to 144, all else equal? e. What would the new equilibrium values of W/P, R/P, Y, S and r be if taxes (T) decreased from 1,500 to 1000, all else equal? Assume that KS = 100.


11. What is “autonomous consumption”? Describe two shocks that would increase a nation’s autonomous consumption. According to the classical model, how would national saving (S) and investment (I) be affected (up, down, or no change) by those shocks? How would the aggregate demand for goods (Yd) be affected (up, down, or no change)? Explain.


12. What is “crowding out,” and why does it happen when government purchases are increased? Would an exogenous increase in autonomous consumption also cause crowding out? Explain.

13. Consider a nation with a marginal propensity to consume of 0.75.

a. What will its marginal propensity to save be? b. What would happen to its consumption (give the direction and size of the effect) if taxes (T) were to increase by 100, assuming that real aggregate income is unaffected? What would happen to private saving? To public saving? To national saving? c. Suppose, instead, that government purchases (G) increase by 100 while taxes remain unchanged. Assuming that aggregate income is unaffected, what would happen to consumption? What would happen to private saving? To public saving? To national saving?


14. Suppose you deposit $200 into a bank for 1 year. At the time of your deposit, goods cost $2.50 apiece. A year later, you withdraw your deposit with interest, which totals $215. At that time, the price of goods has fallen to $2.40 apiece.

a. What was the “real” value of your $200 at the time of your deposit? b. What nominal interest rate did your bank pay you for your deposit? c. What was the rate of inflation over the year that your money was sitting in the bank? d. What real interest rate did you earn on your deposit?
