(h) Does ABC’s technology have economies of scope? Should it merge with another bus company with an identical technology? Please show all calculations below. 59 ECO 204 Chapter 12: Practice Problems & Solutions for The Long Run Cost Minimization Problem in ECO 204 (this version 2012-2013) University of Toronto, Department of Economics (STG). ECO 204, S. Ajaz Hussain. Do not distribute. Answer There are economies of scope whenever: ( ) () () ) () () From above: () Note that: ( ) ( ) ( As such, there are no economies of scope and there is no advantage in merging with an identical company. (i) Assume that ABC is a rational competitive firm with a capacity of 1,000 passengers a day. Denote the price of bus tickets by . Suppose Solve the profit maximization problem: For what range of wages ( ) will ABC choose to sell no tickets, one thousand tickets, and between zero and 1,000 tickets? Show all calculations. Answer The profit maximization problem (PMP) is: Recall that all inequality constraints must be expressed in the form ( ) Having expressed all constraints in terms of ( ) . Therefore: , form the Lagrangian: () [ [ [ [ 60 ECO 204 Chapter 12: Practice Problems & Solutions for The Long Run Cost Minimization Problem in ECO 204 (this version 2012-2013) University of Toronto, Department of Economics (STG).
