We provide a methodology to study the role of market distortions on the emergence of indeterminacy and bifurcations. Most of the specific market imperfections considered in the related literature are particular cases of our framework. Comparing them we obtain several equivalence results in terms...

Considering a finance constrained economy, we discuss the stabilization role of variable labour and capital income taxes under a balanced-budget rule in the presence of consumption externalities of the "keeping up with the Joneses" type. We find that sufficiently procyclical labor and/or capital...

We study employment dynamics using an OLG model with unemployment benefits and universal old-age survival pensions, both financed by taxing employed workers. The novelty is that we explicitly introduce workers' social norms that shape both the individual participation decision of workers and...

We propose and estimate a model where unemployment fluctuations result from self-fulfilling changes in expected inflation (sunspot shocks) affecting nominal wage bargaining. Since the estimated parameters fall near the locus of Hopf bifurcations, country-specific expected inflation shocks can...

We analyse the implications of unions (efficient bargaining) for multiplicity of stationary states and welfare, local indeterminacy, bifurcations and endogenous fluctuations (deterministic and stochastic). We use an overlapping generations model with external increasing returns to scale, where...

In this paper we conduct an analysis of the effects of firing costs in models that consider simultaneously worker heterogeneity, imperfect information on their productivity and union power. We consider an OLG model where heterogeneous workers participate in the labour market both when young and...

In this paper we conduct a theoretical analysis of the implications of a union which can exploit the existence of firm labour adjustment costs. We consider a model involving a large number of identical firms facing a single, economy-wide union. We solve (i) for the Markov perfect equilibria with...

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...

We introduce labour market imperfections (i.e. unions and the existence of a wage floor) in a finance-constrained monetary economy with heterogenous agents and increasing returns to scale due to labour and capital productive externalities. We find that indeterminacy emerges for empirically...

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...
