SOVEREIGN RESTRUCTURING VS. FISCAL ADJUSTMENT IN A MONETARY UNION: MACROECONOMIC EFFECTS FROM MODEL-BASED SIMULATIONS

摘要

We assess the macroeconomic effects of a sovereign restructuring in a small economy belonging to a monetary union by simulating a dynamic general equilibrium model. We compare the macroeconomic outcome of restructuring with scenarios where the debt reduction is achieved via fiscal adjustment. In line with the empirical evidence, we assume that the sovereign debt is held by domestic agents and by agents in the rest of the monetary union; after the restructuring the sovereign borrowing rate increases and the increase is fully transmitted to the domestic households' borrowing rate; and the government cannot discriminate between domestic and foreign agents when restructuring. We also assume that the small economy does not exit from the monetary union after the restructuring and that the restructuring does not have systemic effects on the rest of the union. Our results suggest that the restructuring can imply persistent and large reduction of output, especially if the share of public debt held domestically is large, the private foreign debt is high, and the spread paid by the government and the households does increases.
