Loveman told other casino operators at an industry conference that Harrah's, its competitors and other businesses may have to change how they work - particularly how they finance development - for the rest of his professional life.
"The arms race that has characterized the business over the last several years might have to de-escalate," Loveman said. "There will be a significant sea change in the way in which the balance sheets of these businesses are structures."
Casinos companies - which are seeing revenue decline across the board because consumers are spending less on gambling and the other services casinos offer - generally rely on developing new projects for their growth.
But they can't borrow money cheaply enough anymore to justify new projects.
MGM Mirage Inc., in the midst of building the largest private development in U.S. history, has struggled all fall to secure the last pieces of financing for its $9.2 billion CityCenter Project on the Las Vegas Strip.
With room rates down, airlines cutting flights to Las Vegas and the reduced number of visitors holding their pursestrings tighter, industry analysts question whether the demand remains for CityCenter and other ambitious projects under way or on the drawing boards.
Several projects here already have been delayed, including Boyd Gaming Corp.'s $4.8 billion Echelon, a second high rise for Donald Trump's Trump International Hotel & Tower and a condominium tower for Las Vegas Sands Corp. between its Venetian and Palazzo casinos.
"I don't see any new development coming to this market for the next five to seven years," said Dan D'Arrigo, chief financial officer for MGM Mirage.
For manufacturers like International Game Technology, that means switching gears from selling new casinos their machines to convincing existing casinos they need replacement machines, its chief executive said.
T.J. Matthews, chief executive of the Reno, Nev.-based company, said his job now is to develop machines that entertain customers more effectively and more efficiently.
The company, the world's largest maker of slot machines and casino management systems, offered about 500 employees, roughly 8 percent of its global work force, either early retirement or severance packages. The cuts will cost up to $21 million, the company said Wednesday.
Loveman praised Matthews but said new machines will be a tough sell for casinos worried about polishing their balance sheets.
"Until those imbalances are resolved ... it's going to get very hard to get excited about the next new buffet, the next new food and beverage experience, the next new nightclub experience, the next new gaming experience," Loveman said.
