Over the last three decades, inflation targeting (IT) has become the most popular monetary policy framework among larger economies. At the same time, its constituting features leave room for different interpretations, translating into various central banks' institutional set-ups. Against this backdrop, this book investigates the importance of institutional arrangements for policy outcomes. In particular, the book answers the question of whether there are significant differences in IT central banks' institutional set-ups, and-if yes-whether they influence the ability of monetary authorities to meet their policy goals. The book examines around 70 aspects related to independence, accountability and transparency of 42 IT central banks over the last 30 years. Based on the analysis, it can be concluded that the quality of the institutional set-ups materially affects monetary policy effectiveness. In fact, a visible improvement of institutional arrangements resulting from pursuing an inflation targeting strategy can be treated as its lasting contribution to central banking. Thus, despite the recent critique of the framework, its prospects continue to be rather favourable.
