This paper aims to provide a stochastic, rational expectations extension of Tobin's "Money and Income; Post Hoc Ergo Proper Hoc?". It is well-known that money may Granger-cause real variables even though the joint density function of the real variables is invariant under changes in the...

For an economic system not to exhibit debt neutrality it must be true that changes in the time profile of lump-sum taxes redistributes resources between heterogeneous consumers. OLD models have age heterogeneity because of a positive birth rate. Unless a bequest motive or child-to-parent gift...

The paper addresses two issues that arise in estimation of testing of the real effects of anticipated and unanticipated money. First it is shown that identification of the effects of unanticipated (or unperceived) monetary growth on real output is possible only if the a priori restrict ion is...

The paper presents a general solution method for rational expectations models that can be represented by systems of. deterministic first order linear differential equations with constant coefficients. It is the continuous time adaptation of the method of Blanchard and Kahn. To obtain a unique...

We investigate optimal consumption, asset accumulation and portfolio decisions in a realistically calibrated life-cycle model with flexible labor supply. Our framework allows for wage rate uncertainly, variable labor supply, social security benefits and portfolio choice over safe bonds and risky...

The paper investigates the robustness of the proposition that in stochastic models contingent or feddback rules dominate fiped or openloop rules. Four arguments in favour of fixed rules are considere`. 1) The presence of an incompetent op malevolent policy maker. 2) A trade-off between...

The paper considers the implications of the rational expectations New Classical Macroeconomics revolution for the 'rules versus discretion' debate. The following issues are covered: 1) The ineffectiveness of anticipated stabilization policy, 2) Non-clausal models and rational expectations, 3)...

This paper presents a new solution to the time-consistency problem that appears capable of enforcing ex ante policy in a variety of settings in which other enforcement mechanisms do not work. The solution involves formulating a law, institution, or agreement that specifies the optimal ex ante...

This paper questions the widely accepted view that deficits have real effects in the life cycle model. Standard analyses of deficits within life cycle models treat the government as a dictatorial entity that can effect any intergenerational redistribution it desires. In contrast, this paper...

The paper develops a forward-looking comprehensive accounting framework for the public sector.By integrating the public sector budget constraint forward in time the government's present value budget constraint (PVBC) is obtained. In addition to the familiar financial assets and liabilities,...
