This analysis explores whether a theater company should consider cutting ticket prices. With only 200 seats filled in a typical performance out of 500, the PTC charges $30 per seat. The analysis examines demand function, elasticity, total revenue, factors influencing demand, and advanced issues.
E N D
Players Theater Company • Should the theater cut prices? • The theater has 500 seats; about 200 are filled in a typical performance • The PTC has been charging $30/seat
Demand Function • Q = f(X1, X2,…, Xn) • Example: Q = 117 – 6.6 P + 1.66Ps – 3.3 Pr + .0066I
Demand Curve Ticket Pricein Dollars Income = $50,000 Price of Symphony tickets = $50 Price of meal at nearby restaurant = $40 60 30 Demand 200 Quantity of PTC Tickets 400

Elasticity of Demand • Definition • η = -(% change in Q) / (% change in P) • Calculating

Estimates of Price Elasticities • Sugar = 0.31 • Potatoes = 0.31 • Tires = 1.20 • Electricity = 1.20 • Haddock = 2.20 • Movies = 3.70
Total Revenue, Marginal Revenue • Total Revenue = P x Q • Marginal Revenue = the change in total revenue associated with selling one more unit of the product

Other Factors Influencing Demand • Prices of related products • Complements vs. Substitutes • Defining a Market • Cross Price Elasticity of Demand
Estimates of Cross Elasticities • Electricity and Natural Gas = 0.20 • Beef and Pork = 0.20 • Natural Gas and fuel oil = 0.44 • Margarine and Butter = 0.81
Other Factors Influencing Demand • Income • Normal vs. Inferior goods • Income Elasticity of demand
Estimates of Income Elasticities • Flour = -.36 • Natural Gas = 0.44 • Margarine = -0.20 • Milk = 0.07 • Dentist Services = 1.41 • Restaurant Consumption = 1.48
