In this title, David Stasavage explores several alternative political economy explanations for the persistence of the Franc Zone and its macroeconomic management over the period 1945 to 2000. He addresses the issue of sustainability and asks why the Franc Zone has survived despite several major political and economic shocks that might have easily led to its dissolution. These include decolonisation, France's entry into the European Community and the growing marginalisation of Africa in world affairs. He also considers the issue of credibility and in particular the extent to which the Franc Zone arrangements commit member states to prudent macroeconomic policies.
