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...

This paper studies the possibility of nonlinear dynamics in a simple overlapping generations model with the environment - the John-Pecchenino (1994) model. We show that if people's concerns towards greener preferences and the maintenance efficiency relative to degradation are not sufficiently...

In the present note we construct an overlapping-generations (OLG) example in which free trade is Pareto-improving and the world equilibrium chaotic. The example is simple, but it is not incompatible with the general model of Kemp and Wolik
