Book excerpt: In these timely essays, Nobel prize�winning economist James Tobin shows how Keynesian economics offers corrective treatment for the economic ailments we have faced under the Ford, Carter, and Reagan administrations.Essays in the first part of the book focus on theory and policy in Keynesian economics, particularly on the modern anti-Keynesian movements of the 1970s and 1980s. Tobin's writings on the events, controversies, doctrines, and policies of the Reagan era make up the book's second section, Essays in part three continue to discuss the Reagan revolution, focusing on fiscal policies and presenting some general macroeconomic principles that can be invoked to remedy the situation; those in part four are concerned more specifically with the conduct of monetary policy. A fifth section addresses inflation stagflation, and unemployment, recommending income policies that Tobin believes must become a "permanent tool of macroeconomic policy." The book concludes with several essays on various aspects of political economy, including a timely reminder that economic policies should serve ethical values.James Tobin, who received the Nobel prize in economics in 1981, is Sterling Professor of Economics at Yale.
