evaluate the impact of government interventions, such as antitrust regulations, price controls, or subsidies, on various market structures. Select a specific industry and examine how these interventions have influenced competition, consumer welfare, and economic efficiency. Provide the pros and cons of government intervention.
Consider an economy that exhibits both population growth (L grows at rate n) and
technological progress (A grows at rate a) described by the production function,
Y = F(K, AL) = Ka (AL)¹-α
Here K is capital and Y is output.
(a) Show that this production function exhibits constant returns to scale. [2 marks]
(b) What is the per-effective-worker production function, y = f(k), (where y = Y/AL
k K/AL)? (Show your working.)
[2 marks]
(c) Find expressions for the steady-state capital-output ratio, capital stock per
effective worker, and output per effective worker, as a function of the saving rate
(s), the depreciation rate (8), the population growth rate (n), the rate of
technological progress (a), and the coefficient a. (You may assume the condition
that capital per effective worker evolves according to Ak = sf (k) - (a+n+8)k.)

equal to the parameter a.

- 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.

- 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.

Yes, because P = MC = MR for each of the 3 firms. ○ B. No, because Firm A is not producing at a profit-maximizing level of output. ○ C. Yes, because all 3 firms are producing at their minimum average total cost. OD. The answer is uncertain since it's unknown whether the firms are producing at the minimum efficient scale or not. ○ E.

- 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.)

As the article indicates there are different measures of well-being. You are interested in creating a Hypothesis Test about the economic well-being of the area. Discuss the following issues: First, think about your research hypothesis and justify it briefly. Remember, a hypothesis is a well-thought and untested proposition. What is the null hypothesis? What is the parameter you are interested in? (i.e., the measure of well-being). Is it going to be a Lower-Tail, Upper-Tail or Two-Tailed test?
