Demand & Supply

Price Fluctuations of Gasoline

We are all familiar with fluctuating prices of gasoline at the pump. Why does this happen? Research the recent history of gasoline pricing in your area, and attempt to relate any fluctuations you observe to documented supply and demand factors, as outlined in our book. Be sure to cite any references used. Why do the gasoline

Predict The Annual Number of VCRs Sold

Suppose that the current market price of VCRs is $300, that average consumer disposable income is $30,000, and that the price of DVD players (a substitute for VCRs) is $500. Under these conditions annual U.S. demand for VCRs is 5 million per year. Statistical studies have shown that for VCRs the own-price elasticity of demand is

Calculate optimal profits of each firm.

Two firms produce differentiated products and set prices to maximize their individual profits. Demand functions for the firms are given by Q1 =64 -4P1 +2P2 Q2 =50 -5P2+ P1 where P1, P2, Q1, Q2, refer to prices and outputs of firms 1 and 2 respectively. Firm 1â??s marginal cost is $5 while firm 2â??s marginal cost is $

Relationship between interest rates and the demand for money

About the relationship between interest rates and the demand for money I have to say that it is missing a factor called confidence. Many economists have said before that if the rate declined, the demand for money will rise and the contrary would be true. However, real life even if rates declined to historically low rates, if the

Draw a demand curve

Graph supply and demand schedules and equilibrium

Suppose the market demand for pizza is given by Qd=300-20p and the market supply for pizza given by Qs=20p-100, where P=price (per pizza). Graph the supply and demand schedule for pizza using $5 through $15 as the value of p. In equilibrium, how many pizzas would be sold at what price?
