The aim of the book is to study different features of the finance-led regime that has settled in most industrialized countries since the late 1980s. Capital accumulation is driven by the financial rate of return and periodic crises appear as its normal adjustment mode. Recurrent global imbalances are another component of this growth regime with both a real and financial dimension. They are observed at the world level (US deficits facing Asian surpluses) and regional level (intra-European imbalances). Economic policies have been active to fight against crises, especially after 2008. The worst have been avoided but the mechanisms remain almost unchanged. These questions will be discussed using rather simple macroeconomic models at the national and international levels. The case of the European Union (EU), where the crisis of the euro zone has presented strong specificities due to the inconsistency of the monetary union, will be examined more in detail.
