THE CAREER THERORY of central banker motivations lets us revisit old questions and gain new insights. An important example is the debate among Iversen (1999), Hall and Franzese (1998), and Cukierman and Lippi (1999), who explore the interactive effects of central banks and labor unions on economic performance. This intriguing literature emerged from the insight that if unions have any wage-setting power, then central bankers have the ability to shape the real economy using monetary policy, even over the long run. Yet to date, this work lacks any way to measure a concept at its theoretical core: the conservatism of the central bank. In this chapter, I combine measures of central bank autonomy and conservatism into a new measure of overall central bank nonaccommodation.
