A firm faces the following production function,
Y = AKα L¹-a
(1)
Here Y is output, K is capital, L is fixed labour, and A is a measure of technology.
The firm uses an optimal amount of capital determined by the condition,
MPK = r +8
(2)
Where MPK is the marginal productivity of capital, r is the real interest rate, and ♪ is
the depreciation rate.
(a) Using equations (1) and (2) find an expression for K*, the optimal amount of
capital the firm should use.
[3 marks]
(b) Referring to your result from part (a), comment on what happens to K* when
each of the following variables change (holding other variables constant),
(i)
The measure of technology (A) falls
(ii)
The depreciation rate (8) increases
(iii)
The real interest rate (r) increases

[Hint: For each of parts (i)-(iii) you are being asked to comment on what happens to
K* if just the variable mentioned in the question part changes. Your answer should
state whether K* increases, decreases, or stays the…
In the week-4 materials, when deriving labour supply, we assumed that the
substitution effect dominated the income effect. What impact would there be on
labour supply if this was not the case? Briefly investigate how such a change could
theoretically affect the imposition of a minimum wage above the market clearing
wage. (Your answer is likely to benefit from diagrammatic support.)
Refer to the attached Wk 3 Graph for this assignment. The graph shows an increase in demand (shifting of the demand curve from D1 to D2). Choose an application or situation in the economy or a specific economic situation to describe this graph. Take into consideration the impact on quantity and price in your analysis.
Given your analysis, what would cause the situation to go the opposite way? What would cause the situation to go further into the same direction?

- Wolfgang is a typical producer in a perfectly competitive piano industry (i.e., all other producers of pianos face the same costs as Wolfgang). The following production and cost data apply to the long run as well as the short run. Fixed costs (rent) are unrecoverable in the short run and are equal to $2400 per month. Variable costs consist of raw materials (wire, wood, plastic), which cost $1000 per piano, and the $40 per hour opportunity cost of Wolfgang's time. Wolfgang's production function is given in the table at right. Wolfgang will shut down if the price per piano is less than OA. $3000. B. $4000. O C. $5000. ○ D. None of the above.

- Consider the table on the right, which shows the various revenue concepts for a perfectly competitive firm. Suppose the firm faces a constant market price of $4. Compute first total revenue for each level of output and fill in the TR column of the table. Next, compute marginal revenue for each level of output and fill in the MR column of the table. (Marginal revenue at each level of output is computed using total revenue for two successive levels of output. For example, marginal revenue at 160 uses total revenue for output levels 120 and 160.)
