Demand & Supply

Concepts in Managerial Economics

1. In a competitive market, the market-determined price is $60. For a typical firm producing 100 units of output, short-run marginal cost is constant at $65, average total cost is $95, and average fixed cost is $30. Is this firm making the profit-maximizing decision? If not, what should it do? a) No, it is not making the profit

The Invisible Hand - Adjustment of Supply and Demand

Given that the invisible hand supposedly adjusts market supply and demand, how does it relate to the scarcity of resources? How does the invisible hand increase/decrease the scarcity of resources? Does theory and reality in economics actually differ? If so, why?

Equilibrium price for physiotherapy

The equilibrium price for physiotherapy visits is $30 and the quantity utilized is 150 visits as a result of the demand and supply conditions in this diagram. The state legislature is concerned that the current price does not give the physiotherapists enough incentive to produce a high volume of services. A proposal has been m

Managerial Economics: Demand, Supply, and Equilibrium

Answer all questions, a through f. On questions c, d, e and f show your math. Suppose that the demand and supply functions for good X are as follows: QD = 75 + (.004)*M - 4*P QS = -43 - (.4)*(PI) + 3*P a. Is this good a normal good or an inferior good? How do we know? b. Is the sign correct on the coefficient in f

According to an article in the Wall street Journal, during 2006, the demand for full-size pickup trucks declined as a result of rising gas prices and a decline in housing construction (construction firms are an important part of the market for full-size pickup trucks). At the same time, Toyota began production of trucks at a new

Computation of Equilibrium Market Demand and Market Supply

Assume that the market demand and the market supply are governed by the following equations: Qd=80-4P Qs=6P (i) Is the demand consistent with the law of demand? (II) Is the supply consistent with the law of supply? (iii) What would be the equilibrium price and quantity in this market?

Airline Price Discrimination

Airlines practice price discrimination by charging leisure travelers and business travelers different prices. Different customers pay varying prices for essentially the same coach seat because some passengers qualify for discounts and others do not.
