We extend the finance-constrained economy proposed by Woodford (1986) to incorporate imperfectly insured unemployment, by introducing unions and unemployment benefits financed by labour taxation. We show that this simple extension of the Woodford model changes drastically its stability...

It is known that, in the context of a real business cycle model with constant returns to scale and a balanced budget fiscal policy rule, steady state indeterminacy may arise as a result of endogenous labor income tax rates. In this paper, it is shown that when the government finances its...

We analyze how global economic integration of factor markets affects the stability of the macroeconomy, with respect to expectations-driven fluctuations, when countries differ in their labor market institutions. It is shown that, due to the occurrence of equilibrium indeterminacy, liberalization...

The Paper finds empirical evidence on the ripple effect of sunspots on the interwar German economy. It identifies a sequence of negative shocks to expectations for the 1927-32 period. The artificial economy predicts the 1928-32 depression and a long boom from 1933 onwards. Overall, a tangible...

The Paper approaches business cycles in terms of extrinsic uncertainty related, not to dynamic indeterminacy of intertemporal equilibria (in the neighborhood of an attractor) or to multiplicity of steady states (in non-linear models), but to static indeterminacy of free entry oligopolistic...

This Paper derives new results on the effects of employing Taylor rules in economies that are subject to real-market imperfections such as production externalities. It suggests that rules that should be avoided (chosen) in perfect-markets environments do in fact ensure (yield) unique (multiple)...

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon. These requirements lead to constant interest rate (CIR) instrument rules. Using the standard New...

In this paper we consider a Ramsey one-sector model with non-separable homothetic preferences, endogenous labour and productive external effects arising from average capital and labour. We show that indeterminacy cannot arise when there are only capital externalities but that it does when there...

In this paper, we consider an aggregate overlapping generations model with endogenous labour, consumption in both periods of life, homothetic preferences and productive external effects coming from the average capital and labour. We show that under realistic calibrations of the parameters, in...

We consider a constant returns to scale, one sector economy with segmented asset markets, encompassing both the Woodford (1986) and overlapping generations models. We analyze the role of public spending, financed by (labour or capital) income and consumption taxation, on the emergence of...
