I. Antitrust in Industries whereFirms Manage Revenue

• 1999 Central Parking $585 Million acquisition of Allright.– Divestitures in 17 cities

• Froeb et al. (2002) criticize the Justice Department's enforcement action by arguing that the merger would not have raised price because there is very little uncertainty about parking demand. – Firms price to fill capacity, pre- and post-merger

Antitrust in Industries whereFirms Manage Revenue (I)

• 1999 Central Parking $585 Million acquisition of Allright.– Divestitures in 17 cities

• Froeb et al. (2002) criticize the Justice Department's enforcement action by arguing that the merger would not have raised price because there is very little uncertainty about parking demand. – Firms price to fill capacity, pre- and post-merger

Antitrust in Industries whereFirms Manage Revenue (II)

• 2003, the European Commission (EC) gave their approval to Carnival's $5.5 billion takeover of rival cruise operator P&O Princess– Followed UK and US approvals

• Coleman et al. (2003) summarized the empirical analysis done by the FTC, – no correlation between prices and concentration– no correlation between changes in capacity and changes in

price. – firms were adding capacity, increasing amenities, and

competing on price

Antitrust in Industries whereFirms Manage Revenue (III)

• 2005, six luxury hotels in Paris exchanged information about occupancy, average room prices, and revenue– French competition agency: "Although the six hotels

did not explicitly fix prices, …, they operated as a cartel that exchanged confidential information which had the result of keeping prices artificially high" (Gecker, 2005)

– industry executives insisted that their information sharing was to "to bring more people to the area and to maximize hotel utilization"

Revenue Management: set price before demand is realized

• Firm optimizes expected demand:

• Non linearity of min() function means that capacity constrained firm “shades” price to minimize expected error costs– Over-pricing means unused capacity– Under-pricing means foregone revenue

Testable hypothesesMerger Theory Demand

Uncertainty

Capacity Constraint

Prediction for occupancy

Prediction for price Comment

Unilateral effects: price or quantity competition

Low Not binding

Down, unless outweighed by efficiencies

Up, unless outweighed by efficiencies

P and Q move in opposite directions

Pricing to fill capacity: when demand is known

Low Binding No effect No effect Price to fill capacity, both pre- and post-merger

Stochastic economies of scale: pricing to fill capacity when demand is uncertain

High Binding Up Up, if tightly binding constraint

Jointly managed capacity is easier to fill

Demand externalties:merged firm is able to bid for group business

Varies No effect if capacity constrained; Up if not.

Up, if capacity constrained; no prediction if not.

Demand increases for merged hotel.

Data

• Price and occupancy data from Smith Travel Research (STR).– 32,314 U.S. hotels reported to STR the average room-

night price actually received each day, as well as the total number of rooms available and the number of rooms sold.

– 97 monthly observations from 2001 –2009 for each hotel for occupancy and price.

– These 32,314 hotels represent about 95% of chain-affiliated properties in the United States and about 20% of independent hotels and motels.
