Convention Center Follies

"American cities have experienced a remarkable surge in convention center development over the last two decades, with exhibit hall space growing from 40 million square feet in 1990 to 70 million in 2011--an increase of almost 75 percent. Proponents of these projects promised new jobs, new private development, and new tax revenues. Yet even as cities from Boston and Orlando to Phoenix and Seattle have invested in more convention center space, the return on that investment has proven limited and elusive. Why, then, do cities keep building them?"--Publishers website.
