In this paper we focus on how the necessities from the public sector borrowing requirement are managed in the Government securities markets. We consider in detail the interaction between the demand and supply schedules and, within this context, the role of economic agents and institutions. The interest in the pre-union period is in the analysis of the reasons that made feasible decreasing levels of new issuances as well as interest expenses out of GDP. In particular, after the estimation of a complete interactive structural model, we carry out simulations experiments to highlight the tendencies according to the structure that was operative in the pre-euro phase. Importantly, the results we derive are helpful to asses also on the current structure underlying the debt management and the balance of the public sector.
