"The Economics of the Monetary Union and the Eurozone Crisis" by Manuel Sanchis i Marco provides an in-depth analysis of the economic foundations of the monetary union and the challenges facing the Eurozone. The book connects the theory of optimal currency areas with the current institutional framework of the European Union and highlights the impacts of recent reforms to the Stability and Growth Pact. Sanchis i Marco argues that the lack of strong political leadership in the EU poses a significant barrier to establishing a true economic and monetary union. This could not only jeopardize the entire project but also undermine the internal macroeconomic logic of a common currency like the euro. The book is particularly relevant for understanding economic developments in the Eurozone and offers valuable insights into the necessary adjustments required from both core and peripheral countries to stabilize the Eurozone.
