Abstract: | Theoretical macroeconomic models typically take fiscal policy to mean tax‐and‐spend by a ‘benevolent government’ that exploits potential aggregate demand externalities inherent in the imperfectly competitive nature of goods markets. Whilst shown to raise aggregate output and employment, these policies crowd‐out private consumption and typically reduce welfare. On account of their widespread use to stimulate economic activity, we consider the use of ‘tax‐and‐subsidize’ instead of ‘tax‐and‐spend’ policies. Within a static general equilibrium macro‐model with imperfectly competitive goods markets, we examine the effects of wage and output subsidies and show that, for a small open economy, positive tax and subsidy rates exist which maximize welfare, rendering no intervention suboptimal. We also show that, within a two‐country setting, a Nash non‐cooperative symmetric equilibrium with positive tax and subsidy rates exists, and that cooperation between governments in setting these rates is more expansionary and leads to an improvement upon the non‐cooperative solution. |
