Chapter 2: Fiscal Policy in the Eurozone

This chapter is devoted to fiscal policy theory and to how its evolution influenced the policy principles implemented from the end of the World War II to the present. It shows how the theoretical foundations evolved, from the Keynesian theory according to which public expenditure was conceived as an instrument to sustain aggregate demand and achieve full employment, to the present theoretical framework in which, following the intertemporal approach, it has been downgraded to an external shock. The public debt issue is examined with the aim of explaining why sound public finance represents a primary policy objective in the Eurozone.
