| Abstract: | Existing studies on the fiscal multiplier under imperfect competition assume a symmetric market structure with identical firms. This paper examines the fiscal policy implications of introducing a multisectoral economy, where a composite commodity is offered in many varieties within a market of monopolistic competition and a homogeneous good is produced in a perfectly competitive environment. Within the context of this mixed industrial structure we show that the size of the short-run multiplier crucially depends on the composition of public expenditure chosen by the government. |
