Suppose a firm operates in a perfectly competitive market where every firm has the same cost function given by:

C(q)=5q²+q+20

Suppose initially the market price is p=31.

How much output will this firm produce?

At the price p=31, how much profit does this firm make?

Now suppose the market price changes. Below what price will this firm shut down? (what is the "shut-down price")

At what price will this firm earn zero profits (what is the "break-even price")?

Suppose the market consists of 20 firms. The market demand is Q_D=602-2p. What will be the short-run equilibrium price?

Suppose the market consists of 20 firms. The market demand is Q_D=602-2p.

What will be the short-run equilibrium output per firm?

Continuing with the previous question:

Suppose the market consists of 20 firms. The market demand is Q_D=602-2p.

What will be the short-run equilibrium market quantity?

Continuing with the previous question:

Suppose the market consists of 20 firms. The market demand is Q_D=602-2p.

In the long run, what do you expect to happen to the number of firms in the industry, the market price, margkey quantity, and output per firm?

Sandboxes are produced according to the following cost function:

c(q) = q² + 100

where the fixed cost of 100 represents an annual license fee the firms pay. Every firm uses the same technology to produce sanboxes.

In the long run, what will be the equilibrium price?

The market demand for sandboxes is given by Q_D = 1500 – 5p. Find the long-run equilibrium market quantity.

The market demand for sandboxes is given by Q_D = 1500 – 5p. Find the long-run equilibrium number of firms.

Recent trends have increased the demand to Q_D=2250–5p. In the short run, what will be the new equilibrium price? (Note: you will need to use the number of firms you found in the previous question to find this)

Suppose demand remains high at QD=2250–5p in the long run.

What will be the long-run equilibrium price?

Suppose demand remains high at Q_D=2250–5p in the long run.  

What is the number of firms operating in the long run?

Suppose the operating fee is increased from 100 to 225. So now each firm has the cost function

C(q)=q² + 225

In the long run, with the demand Q_D=2250–5p, what will be the equilibrium price?

How did raising the operating fee from $100 to $225 affect the firm's profits in the long run? (compare the profits in the previous question to to the profits in the first question in this story).

2018 average figures (i.e.: not job-specific) show women working a full-time job earning 81.1% as much as male counterparts. When controlling for occupational distributions this gap noticeably narrows (although it does not eliminate the disparity).

Part 1.

Although a gender pay gap is unfortunately still present even when controlling for occupational distributions, explain why the gap narrows. In other words, why does an average (woman/men) pay gap figure show a larger degree of disparity? Make sure to use proper terminology from your textbook (chapter 19).

Part 2.

As the country's economic activity shrinks and only certain 'essential' industries continue to work (ex.: healthcare, mass transit, fire and public safety, military, food and agriculture, energy and infrastructure, media, mail and few others), how do you believe gender pay gap statistics will be impacted as a result of COVID-19? Will the pay gap widen or narrow?, why?

Suppose that the country of VIRUS is currently operating in FREE TRADE arrangement with its closest neighbour, VACCINIA. VIRUS, however, is currently going through a difficult economic period, and its largest domestic producer of goods and services is demanding that VIRUS’S Government implement a TARIFF on all goods being imported from VACCINIA to protect the VIRUS’S domestic economy.

(i)     The Prime Minister of VIRUS has hired you as she is uncertain what to do. She has asked you to (1) Explain Carefully to her exactly what a “Tariff” is and how a “Tariff” will alter the domestic market, AND (2) What will be the eventual impact on each of CONSUMER SURPLUS and PRODUCER SURPLUS compared to the current “Free Trade” position.

When prices rise above equilibrium:

A. producer surplus falls and consumer surplus rises.

B. producer surplus falls and it is uncertain what happens to consumer surplus.

C. consumer surplus falls and it is uncertain what happens to producer surplus.

D. producer surplus falls and consumer surplus falls.

Say which answer choice it is and why.

10-12 please answered with work please? The multivariate demand function (below) is needed for questions 6 – 12. Setting: U.S. Auto manufacturers are trying to develop a multivariate function with which to estimate the demand for their gas-electric hybrid compact cars. Here is one that Motors General developed for its Jolt: Qj = 65000 – 20Pj + 20Pf + 35Pt – 5Pb + 0.2Tc + 0.05Y + 10Mg + 0.04A Where Qj = the number of Jolts demanded per week. Pj = the price of each new Jolt (in $). Pf = the price of each new Ford gas-electric hybrid (in $). Pt = the price of each new Toyota gas-electric hybrid (in $). Pb = the price of replacement batteries for the Jolt (in $). Tc = the amount of tax credit incentive offered with the purchase of a new hybrid (in $). Y = average weekly disposable income of a typical Jolt purchaser (in $). Mg = the miles per gallon of gas rating of the Jolt (in miles per gallon). A = average weekly Jolt advertising expenditure (in $).

10. Enter the following values into your Jolt demand function (be very careful with the calculation because the resulting quantity of Jolts demanded will be used in several questions to follow). Circle your answer on the answer sheet. Pj = $45000 Pf = $40000 Pt = $45000 Pb = $7000 Tc = $8000 Y = $1000 Mg = 55 A =$20000

11. What is the point cross-price elasticity of Jolt demand with respect to the Toyota price (Pt) of $45000? Work out completely and show the sign (+ or -); carry out to 3 decimal places.

12. What is the point elasticity of Jolt demand with respect to the advertising expenditure (A) of $20000. Work out completely and show the sign (+ or -); carry out to four decimal places.
