Cost efficiency was the initial goal of privatization--achieved in many cases but not consistently. Public services provided by the private sector were cheap in the beginning but became increasingly expensive, especially to low-income citizens. The lessons learned from early successes and failures gave birth to a new goal--effectiveness of services, as measured by accountable results.

In its updated second edition, this collection of essays explores the good and the bad sides of privatization.
