Mr. A owns 1,000 shares of General Electric common stock. If he tries to sell some, he finds he can get a price of \(\$ 61.50\) per share for all 1,000 shares. If he offers only 500 shares, he can get a price of \(\$ 61,625\) which is \(\$ 0,125\) more per share. That is, reducing his amount sold by a half, he can get a price that is higher by about \(1 / 500\). If he sought a price of \(\$ 61.75\), he would sell nothing. Mr. A considers this an insignificant rise in price as a result of withholding his supply. Is this an example of a price- takers' market? Compute \(\mathrm{Mr}\). A's marginal revenues as best you can with the given data.
Suppose an economy possesses presently 60 million automobiles; and that each automobile must be replaced every 5 years. Suppose also that the present population of 240 million people grows \(2 \%\) per year. Calculate on the basis of these data, all other things remaining equal, the expected demand for automobiles for this year.
Given that firm \(\mathrm{A}\) has demand function \(\mathrm{P}=15-.05 \mathrm{q}\) and total cost function, \(\mathrm{TC}=\mathrm{q}+.02 \mathrm{q}^{2}\) a) find the point of profit maximization b) find maximum profit if a \(\$ 1 /\) unit tax is imposed.
Assume that a firm operates with the total revenue (TR) and total cost (TC) functions: \(\mathrm{TR}=41.5 \mathrm{Q}-1.1 \mathrm{Q}^{2}\) \(\mathrm{TC}=150+10 \mathrm{Q}-0.5 \mathrm{Q}^{2}+0.02 \mathrm{Q}^{3}\) where \(\mathrm{Q}\) represents the quantity of output produced and sold. a) Determine the profit-maximizing output level for this firm via the \(\mathrm{TR}-\mathrm{TC}\) approach. b) Solve for the profit-maximizing output level by using the \(\mathrm{MR}=\mathrm{MC}\) approach
YCorporation, a manufacturing entity, has the following profit function: \(\pi=-\$ 10,000+\$ 400 \mathrm{Q}-\$ 2 Q^{2}\) where \(\pi=\) Total profit and \(Q\) is output in units a) What will happen if output is zero? b) At what output level is profit maximized?
