This area is dedicated to documents focused on the analysis of macroeconomic theoretical models which include, as one of the relevant variables, the level of public debt regardless its operative aspects. As a macroeconomic variable, public debt is generally taken into account in a number of research projects, both theoretical and empirical, especially concerning topics such as the inter-temporal government budget constraints, the intergenerational redistribution, the efficiency of taxation, the welfare analysis and the private saving behavior.
