Find the output level at which the average variable cost is minimized.

Consumer Behavior

 

1. Graph the following indifference curves for the given utility levels:

U (x, y) = min {X, Y} for U = 20, 30, 40. (What kind of relationship exists between these goods? Substitutes, Complements?

 

1. Consider the utility function for a utility maximizing individual consuming two goods X and Y.           U (X,Y) = Y² X + (30/2). This person pays 3 dollars for good X and 4 dollars for good Y with an income of 90 dollars. (3 X + 4 Y ≤ 90) Budget constraint. The marginal utility functions for good x and good y are respectively U_x = MU_X = Y² and U_y = MU_Y = 2 X Y
2. Find the marginal rate of substitution between x and y.
3. Find the amounts of good X and Y that maximize this utility.
4. Compute the corresponding utility.

 

Producer Behavior

1. Suppose the following production function: Q = 10 (K)^1/3 (L)^2/3 subject to:

W *L + r * K = Cost.

8. Suppose that K the amount of capital is K =8. If this company hires 64 workers (L), calculate the value of Q.
9. Determine if this production function exhibits constant, increasing, or decreasing returns to scale.

Costs

1. Consider the following cost and benefit functions:

C(X, Y) = 15 (10 X + 2 X²)   with   MC (X) = 15(10 + 4X)

B(X, Y) = 5 (80 X – 2 X² + 40 Y – Y² + 2 X Y) with MB (X) = 5 (80 – 4 X + 2 Y)

Consider Kohlberg’s three levels of cognitive moral development as described in your text. Where do you think you fall?

Paper details:

Assignment Guidelines Respond to the below questions within this week’s journal reflection: * (Take this self assessment) regarding your characteristics that relate to ethical judgement and action * When you receive your results from the assessment, copy/paste those onto a Word document, and add a section with the heading of “Insights” and answer the following questions 1. Based on the information from the text, how could your standings on each of the characteristics (Locus of Control, Machiavellianism, and Moral Disengagement) impact your ethical judgment and action 2. Consider Kohlberg’s three levels of cognitive moral development as described in your text. Where do you think you fall? How do you think your leadership may be affected by where you fall? 3 As a leader, how will you use knowledge about these characteristics (in general, i.e., not particular to yourself) to facilitate ethical behavior in your organization/among your employees? Parameters: The length of your paper will vary based upon the effort required to accomplish each of the goals that are specified. You are expected to write in depth to offer evidence of the knowledge you are acquiring as well as your critical thinking. Reflection journals are typically written in the first person, referring to how you personally relate to the ideas and concepts that we are studying, and how you expect to apply the concepts to your own experiences in the future. Personal pronouns are useful in a reflection journal. Although you are writing in the first person, whenever you refer to concepts that come from sources, you are expected to offer an in-text citation and a corresponding full reference, following APA formatting requirements. It is not necessary to have a cover page or separate out the reference page. These pages were upload from book this textbook below: Also, cite work. Textbook: Treviño, L. K., & Nelson, K. A. (2021).

Note on Converting the payoff table to opportunity loss (OL) table

 

Refer to Table 3 or Table 4 in pages 670-1 of the textbook (Tables 20.3 -4 page 20-4/5 in BB) -in Decision making chapter

 

For the Payoff table (Table 3);

 

	A1: Gradual	A2 Concentrated
E1: low demand	1	-5
E2: High demand	4	10

 

You may think this way to get opportunity loss table:

 

• if in Low demand, E1, you will choose gradual alternative and profit is 1, OL of gradual action is 0, but OL of the Concentrated alternative is 6, because you lose 5, in fact, you could make 1, so the amount of regret(OL) is 6

 

OL = largest payoff in the line (event) – the payoff of the cell

 

• If in High demand, E2, you will choose Concentrated, OL is 0, for Gradual OL= 10 – 4 = 6

 

Key is to think in one event i.e. low demand at a time and move to the next event i.e. high demand

 

The Opportunity Loss table is:

 

	A1: Gradual	A2 Concentrated
E1: low demand	0	6 ß(1- (-5))
E2: High demand	6 ß (10 – 4)	0

 

 

 

Question:  For the following Payoff table, answer questions a) – e) (40 Pts)

 

Events	Probability	A1	A2
E1	.3	1	-5
E2	.5	4	1
E3	.2	6	16

 

 

1. Convert to the Opportunity Loss table
2. Find the optimal act under the maximin criterion
3. Find the EMV (A1) and EMV(A2) and optimal act under the EMV criterion
4. Find the EOL (A1) and EOL(A2) and optimal act under the EOL criterion
5. Find the EVPI
