Think about a purchase that you made recently. Explain how you might have applied the "economic way of thinking" in making your purchase? (10 points)

The efficient number of workers a firm should hire is at the point where the marginal revenue product of an extra worker (that is, price of product x number of units the worker produces) is equal to the cost or wage of that worker. For example, if you pay your worker $100 per day (the Marginal Cost), as long as that worker continues to bring in more than $100 a day (Marginal Revenue) you may continue to hire more workers. The optimal point is when the wage (or MC) is equal to the revenue (or MR) that the worker generates for the company. That is, where MC = MR. So, here is a scenario. Amy owns a fish shop.

Number of students: 1 2 3 4 5 6 7 8 Quantity of fish (kilograms): 20 50 90 120 140 150 150 140

Use the data above to calculate the MP (marginal product) of workers. If all fish shops in Amy's area pay their packers $5 an hour, how many students will Amy employ? Assume Amy sells her fish for $0.50 a kilogram. Explain your answer and show all calculations. (20 points)

3. The table below shows a car manufacturer's total cost of producing cars.

Q TC TVC AVC AFC ATC MC 0 $500,000 1 540,000 2 560,000 3 570,000 4 590,000 5 620,000 6 660,000 7 720,000 8 800,000 9 920,000 10 1,100,000

For each level of output, calculate the total variable cost [TVC], the average variable cost [AVC], the average fixed cost [AFC], the average total cost [ATC], and the marginal cost [MC]. What is this manufacturer's fixed cost? Explain how you derived this. What is the minimum average cost output quantity? Explain how you derived this. Create a single, well-labeled diagram that shows the manufacturer's AVC, ATC, and MC curves. (35 points)

Kyle eats two types of fruits - bananas and apples. He has a budget of $50 to spend on fruits per month. The price of bananas is $5 and that of apples is $10. Graph Kyle's budget line by plotting bananas on the horizontal axis and find the slope of his budget line. Write down the budget equation for Kyle's consumption of fruits (bananas on the horizontal axis). Suppose the price of bananas has doubled. Show this effect graphically and calculate the slope of the new budget line (bananas on the horizontal axis). Suppose Kyle now reduces the money spent on fruits to $40. Show this effect on a graph and calculate the slope of the new budget line (bananas on the horizontal axis; price of bananas is $5 and price of apples is $10).

[1:35 AM, 2/14/2022] Fridah: Please comment on the trend in General Motors's operating income over the past five years.

Please remember that Beta is a measure of risk that consequently drives the cost of equity number and the weighted average cost of capital. Please review General Motors's beta and comment on whether you believe this to be an accurate representation of General Motors's risk.

Review the market weights of debt and equity for General Motors relative the others in the industry. Is this level of debt too high, too low, misrepresented? Why?

Review General Motors's economic profit trend for the five years. Is this trending in the right direction, too high, too low, misrepresented because of some factor? How or why?

Remember strengths are internal to the firm and... [1:55 AM, 2/14/2022] Fridah: 1. Why is it just as important for non-IS professionals? How are they involved in this process? What is their role in making IS investment decisions?

2. Why can it be difficult to develop an accurate cost-benefit analysis? What factors may be difficult to quantify? How can this be handled? Is this something that should just be avoided altogether? What are the consequences of that approach?

3. Contrast the cost of acquisition versus the total cost of ownership for the purchase of a new car. Demonstrate how the type of car, year, make, model, and so on change the values of various types of costs and benefits.

4. Identify and describe three different situations where fear, faith, or fact arguments would be most compelling when making an information systems investment decision.

5. Contrast the differing perspectives of different stakeholders involved in making information systems investment decisions.

6. Explain the differences between data and data flows. How might systems analysts obtain the information they need to generate the data flows of a system? How are these data flows and the accompanying processing logic used in the system design phase of the life cycle? What happens when the data and data flows are modeled incorrectly?

You are associated with a corrupt broker in Philadelphia. The broker has paid for tomorrow's orange juice report, which reports on the crop conditions in florida. The report will be released @ 10 am tomorrow. The market demand and supply curve that exist now, and at the opening of the market, tomorrow, at 9 am are: a) The equation for the market demand for oj is P = 230 - .5 Q b) The equation for the market supply for oj is P = 80 + .5 Q. If the crop is damaged, it will change the slope of the appropriate curve by 1/10 for every 10% of damage: so, for example 30% of damage will change the slope of the appropriate curve from .5 to .8, this is the only effect on the curves. Your boss has a copy of an erroneous report that says 20% of the crop is damaged, importantly, he does not know this is an erroneous report, he bribed an official for this report, and the official, maliciously gave him erroneous data. He is operating under the assumption that he has the correct report, and only he has it. The following day, the market opens unchanged (using the equilibrium price derived above in (a) & ( b)) at 9 am (before the report). Up to what price will your corrupt boss buy or sell oj? If your boss raises the price of oj in buying it, or lowers it by selling, up to what price should he stop buying, or selling (or perhaps you could take the opposite side of the trade..)? Assume that only your boss's actions will move the price. When the actual report is released at 10 am (ceteris paribus), and your boss has pushed the market to the level he expects due to the fictitious crop report, and the market will return to its 9 am equilibrium, what will happen? 5 pts each for the correct price: there are 2: a. the opening price at 9 am, b. the price just before the report's release at 10 am (assuming your boss has pushed the price to its maximum (minimum) level based on his evil expectations. 2 pts for deciding whether your corrupt boss is a buyer or seller. 2 pts for your opinion on whether crime pays in this case.
