This book examines infrastructure privatization, worldwide and particularly in the United States, by investment banks as one way to promote economic growth and productivity. More specifically, it focuses on the Macquarie Group Ltd. From its modest beginnings is Australia some forty years ago Macquarie has achieved preeminence as the world’s leading non-governmental operator of infrastructure assets. The infrastructure fund model pioneered by Macquarie leases (or buys) staid assets ranging from toll roads to airports, piles on debt, and reaps handsome fees.
