1.Let’s say at our current level of production, producing one more unit of output would increase total revenue by $20 and increase total cost by $30. Should the firm increase or decrease its production? What does this have to do with the MR = MC condition?

2.The neoclassical theory of consumption can be summarized as individuals having “Champagne tastes on beer budget”. Explain what this quote means in terms of preferences and budget constraints. How does this quote help us understand the neoclassical theory of how individuals make consumption choices?

3. Say we have an indifference curve that shows us all the combinations of two goods (face masks and hand sanitizer) that make us equally happy. If the amount of face masks I consume is on the y-axis and the amount of hand sanitizer I consume is on the x-axis, my marginal rate of substitution (MRS) will tell me how many face masks I am willing to give up to get one additional hand sanitizer. Why does the MRS diminish (get smaller) as we go further down this indifference curve (as I get more and more hand sanitizer)?

The firm should DECREASE it's Production.

Producing one more unit of output will increase total revenue by $20 i.e., marginal revenue MR of one additional unit of output is $20. Producing one more unit of output will increase total cost by $30 i.e., marginal cost MC of one more additional unit of output is $30. As MC > MR, this additional unit of output produced will reduce the profits of the firm and hence the firm should DECREASE it's Production so as to increase it's profits by producing less.

A firm produces that level of output where marginal cost is equal to marginal revenue ( MC= MR). If MC > MR , then the cost of producing one additional unit of output is more than the revenue earned from the sale of that additional unit of output. As such, this would Decrease the profits of the firm and the firm will reduce it's Production to increase it's profits by producing less. If MR > MC , then the cost of producing an additional unit of output is less than the Revenue earned from the sale of that additional unit of output. As such, this would increase the profits of the firm and the firm would increase it's Production. When MC = MR, then the cost of producing an additional unit of output is equal to the revenue earned from the sale of that additional unit of output and hence the firm would maximise profits and there would be no incentive to increase or decrease the production. Here, as MR is $20 which is less than MC of $30, the firm should DECREASE it's Production and produce where MC= MR.

The CEO's next question is, "What level of output would be required to maximize our profit on the MiniZ?" You have calculated the variable cost per unit for different levels of production. From market research, you have a schedule of prices for these levels. The information for MiniZ is summarized in the table below: Number of Units Variable Cost per Unit ($) Sale Price per Unit ($) 200 60,000 70,000 250 54,000 66,000 300 48,000 64,000 350 46,000 59,000 400...

1. At the current level of output, suppose the actual price level is less than the price level that individuals expect (i.e., Pt < Pet). We know that: A. output is currently below the natural level of output. B. the interest rate will tend to rise as the economy adjusts to this situation. C. the nominal wage will tend to increase as individuals revise their expectations of the price level. D. any subsequent reduction in the aggregate price level will...

1. Suppose a perfectly competitive firm in the short-run is currently producing an output level of 50,000 units, charging a price per unit of $4. The firm incurs variable costs of $280,000 in producing this level of output. It also has fixed costs of $60,000. a) Calculate the economic profit (or loss) from the firm producing and selling these 50,000 units of output. b) Calculate the economic profit (or loss) from the firm shutting down and producing zero units. c) Given the correct...

1. Let’s think about a per unit production subsidy. Start with an initial equilibrium price of $5 and quantity of 100 million. Now provide producers with a $1 per unit subsidy. Shade in (the cost of) the subsidy, make up numbers for the new quantity exchanged, the price consumers face (Pc) and the price producers get (Pp). Ideally you can do this without simply copying it from the book... try it over several days until you can. 2. The goal...

Harris Company has a current production level of 20,000 units per month. Unit costs at this level are: Direct materials $0.25 Direct labor 0.40 Variable overhead 0.15 Fixed overhead 0.20 Marketing - fixed 0.20 Marketing/distribution - variable 0.40 Current monthly sales are 18,000 units. Jimi Company has contacted Harris Company about purchasing 1,500 units at $2.00 each. Current sales would not be affected by the one-time-only special order, and variable marketing/distribution costs would not be incurred on the special order....

Waterways is considering mass producing one of its special-order screens. This would increase variable costs for all screens by an average of $0.62 per unit. The company also estimates that this change could increase the overall number of screens sold of 10%, and the average sales price would increase of $0.22 per unit. Waterways currently sells 432,730.0000000000 screen units at an average selling price of $26.00. The manufacturing costs are $6,039,891 variable and $1,804,120 fixed. Selling and administrative costs are...
