Effectiveness of Fiscal Policy in a Model of Imperfect Competition with Transactions Money.

This paper examines the effectiveness of fiscal policy in a general equilibrium macromodel with transactions money and an oligopolistic product market. The results suggest that although money may be neutral and play no direct role as a policy instrument, its indirect impact on the effectiveness of fiscal policy can be quite substantial. In particular, when money balances feature as a choice variable in the households' objective function, (i) fiscal policy becomes ineffective as the weight attached to money is reduced; (ii) the fiscal multiplier becomes negative when the elasticity of substitution between money and leisure exceeds unity; and (iii) it is possible that policy effects are in fact enhanced as the product market becomes more competitive.
