The basic motivation for this book is my lifelong interest in the relationship between political processes and macroeconomic outcomes especially in the area of monetary policy. Nowadays monetary policy is an area where political considerations are believed by scholars to regularly impact upon economic results. In contrast when my interest in this subject began thirty years ago the scholarly literature on monetary policy hardly ever mentioned systematic political influences. My dissertation at the University of Illinois in 1966 and my first article (in the Joumal of Political Economy in 1967) addressed the modeling and estimation of the concerns that propel monetary policy. In the political and economic turbulence of the period from the late 1960s through the early 1980s it became clear that the directions taken by monetary policy were changing with some frequency. My research during that period dealt with models of monetary policy. In attempting to measure these changes it suggested that monetary policy reactions to the state of the economy were not stable over time. During this period I became interested in reforms which might reduce the resulting instability in the economy. For example my 1972 article in the Joumal of Political Economy suggested systematic penalties Federal Reserve officials who failed to meet the goal of monetary stability by tying their budgets or salaries inversely to the rate of inflation.
