Suppose you were to run a regression of advertising expenditures by firms on firm profits. We would expect that firms with low profits do not spend much. High-profit firms may or may not spend much. The results from this regression will be subject to:
A. multicollinearity.
B. heteroscedasticity.
C. autocorrelation.
D. specification bias
Homework Answers
This is problem of Hetroscedasticity .
As firm's profit increases, the variability of advertisement expenditure will increase .

Suppose a monopolistic competitor faces the following costs and demand in the short run: Part 1 (1 point) What is the amount of profit this monopolistic competitor will make in the short run? Part 2 (4 points) Since this is a monopolistic competitor, the number of firms competing in the long run will(a) , leading the profits for this firm to (b) If this were a monopoly instead, we would expect the number of firms to (c) and profits to (d)

Short-run Equilibrium: Bumper sticker firms produce bumper stickers in a perfectly competitive market. Each identical firm has a short-run total cost function equal to: STC (Q) = 3 + 2q + 2Q2. Suppose that there are 100 firms, and the market demand is D(P) = 100 - 5P where D(P) is the quantity consumed in the market when the market price is P. 1. What is the short-run equilibrium price? 2. How much does each firm produce? 3. Are they...

6. Suppose that the trucking market is a perfectly competitive industry in long run equi librium. Each of the identical trucking firms has the same (long run) cost function: TC = 2250 + 10q2, where q is the volume of sales by each establishment. Each of the identical firms therefore have the same marginal cost: MC = 20q (a) What is the average cost function for the identical trucking firms? (b) How much does each individual firm produce in the...

3. Consider a market of two firms with demand given by P = 200 – Q. Each firm has a constant marginal cost of $20 and fixed costs of $2,000. Competition is characterized by making simultaneous profit-maximizing quantity decisions. a. What will be an individual firm’s quantities and profits if n = 2? n = 3? n = 4? (Make sure to include fixed costs in your profit calculations.) b. Assuming no changes to demand or cost structure, how many...

Consider a perfectly competitive market with many identical firms. Each firm has a long-run marginal cost function given by LRMC(y) = y ^2 + 1. We do not know the firms’ LRAT C function, but we know that at a quantity of 3 it is equal to LRMC. In other words: LRAT C(3) = LRMC(3). (a) Find an expression for an individual firm’s long-run inverse supply curve: this will be p as a function of y. Note that it will...
