Three of the fundamental economic questions or choices that a society has to deal with are: What to produce? How to produce? and For Whom to produce? Discuss how these three basic questions are answered or decided in a market system.

Consider a firm with a production function of the following form:F (L, K) = L(1/4)K(1/2)

20

the corresponding marginal products are
MPL = 1 L(−3/4)K(1/2)

4 20MPK = 1 L(1/4)K(−1/2)

2 20
The cost of a unit of labour is the wage rate w and the cost of a unit of capital is the

rental rate r. The firm is free to adjust all factors of production. (19 points)
a. Does this production function exhibit decreasing returns, increasing returns, or

constant returns to scale?

b. Set up the cost minimization problem and derive the conditional input demand functions for the firm.

c. Provide an expression for the total cost curve for a given level of output q (the cost function should be a function of only the exogenous variables).

what are some of the social conditions that changed for children, women and families as a result of women's activism in the 20th century? why do you think women were able to enact change despite their presumed lack of influence and inability to vote at that time in history?

Consider the four generations of workers now in the workplace. Identify a worker you know from each generation. How do they fit into their generational stereotype? How do they differ? Are there rea- sons other than age that accounts for the similarities and differences in workers?

The topic of this discussion is marginal analysis. The goal of this discussion is to apply the marginal concept in a unique way. Specifically answer this prompt: Craft a scenario and a numeric problem for other students to solve using the Marginal Benefit/Marginal Cost framework. Explain how the "MB" and "MC" are defined in your scenario, and why they increase, decrease or remain constant. Try to use your scenario to explain some behavior or phenomenon that may be puzzling at first glance. You can use any example appropriate (some example ideas could be asking: "Do people wash their car until it is 100% spotless?". "Why does food waste occur?" "Cell phone use while driving on the freeway?" "Using 100% of the toothpaste from the tube?")  Be creative!

(Example response: Food waste and yogurt. Many people throw away their yogurt container with still some edible yogurt inside; it is rare to find someone who will scrape the yogurt container 100% clean. In this example, the quantity or "Q" will be defined as "number of spoonfuls of yogurt," the marginal benefit "MB" is the value of each additional spoonful of yogurt to the consumer (measured in dollars), and the marginal cost "MC" is the effort required to obtain additional spoonfuls of yogurt from the container (measured in dollars). In this example, as the consumer eats more and more yogurt, she gets more full, so the value of each additional spoonful is decreasing (therefore the MB is decreasing). She values the first spoonful of yogurt the most because she is the most hungry at that time, and she values the last spoonful of yogurt the least because she is the most full. The cost of obtaining additional spoonfuls or the MC will be increasing, since the first spoonful will be easy to acquire because the yogurt is plentiful but when the yogurt is close to being finished, the cost of obtaining additional spoonfuls is higher.

Multiple choice question: Let's imagine we have 4 total spoonfuls available in the container, the MB of each is: $5, $4, $2, $1 respectively and the MC of each is: $1, $3, $4, $9. How much yogurt should our consumer eat to maximize total net benefits (TNB)?

• A) 1 spoonful: TNB is $4
• B) 2 spoonfuls: TNB is $9
• C) 2 spoonfuls: TNB is $5
• D) 3 spoonfuls: TNB is $11
• E) 4 spoonfuls: TNB is $12
  1. Clearly defined scenario to explain using the MB/MC framework
  2. Clearly defined quantity, MB, and MC
  3. A multiple choice problem for other students to answer

Q4 .

On 26 February, Hong Kong’s Financial Secretary Paul Chan announced that all permanent residents in Hong Kong will receive a HK$10,000 from the HKSAR government. This policy will cost the HKSAR government roughly HK$71 billion and it is aimed at tackling the worse economic downturn that the city has experienced in the last 10 years.

a. Briefly explain why this policy can increase equilibrium output in the short run .  

b. An economist argues that if the HKSAR government spends HK$71 billion on goods and services instead of giving each Hong Kong resident a HK$10,000, the policy effect on output would be larger. Briefly discuss the economic rationale behind this economist’s argument.

Assume that the following conditions exist. a. All banks are fully loaned​ up-there are no excess​ reserves, and desired excess reserves are always zero. b. The money multiplier is 5. c. The planned investment schedule is such that at a 6 percent rate of​ interest, investment is ​$1200 ​billion; at 5​ percent, investment is ​$1220 billion. d. The investment multiplier is 4. e. The initial equilibrium level of real GDP is ​$12.00 trillion. f. The equilibrium rate of interest is 6 percent.   Now the Fed engages in expansionary monetary policy. It buys ​$2 billion worth of​ bonds, which increases the money​ supply, which in turn lowers the market rate of interest by 1 percentage point. Calculate the increase in money​ supply: ​$____billion. Calculate the increase in real​ GDP: ​$____billion. Calculate the new equilibrium real​ GDP: ​$____trillion.
