We revisit the study of the dynamics of a duopoly game à la Bertrand with horizontal product differentiation and bounded rational firms analysed by Zhang et al. (2009), (Zhang, J., Da, Q., Wang, Y., 2009. The dynamics of Bertrand model with bounded rationality. Chaos, Solitons and Fractals 39,...

We analyse the stability issue in a Cournot duopoly with asymmetric unionism and heterogeneous players. We show that labour market institutions matter or the stability of the unique interior Cournot-Nash equilibrium. Interestingly, the role played by the existence of firm-specific unions on...

We analyse the dynamics of a Cournot duopoly game with heterogeneous players to investigate the effects of micro-founded differentiated products demand. The present analysis, which modifies and extends Zhang et al. (2007) Zhang, J., Da, Q., Wang, Y., 2007. Analysis of nonlinear duopoly game with...

We study the local stability properties of a duopoly game with price competition, different product quality and heterogeneous expectations. We show that the Nash equilibrium can loose stability through a flip bifurcation when the consumer’s type range increases. This result occurs irrespective...

In this paper we link endogenous fertility, endogenous longevity, economic growth and public policies – represented by public health investments and child policies – in a basic overlapping generations model. We found that there even exist four equilibria, and thus low and high development...

Using a simple overlapping generations small open economy, we show that endogenous longevity – through public health expenditure – may reduce both the saving rate and per capita domestic income, while increasing the per capita foreign debt in a country. Moreover, despite funding public...

We analyse the effects of the introduction of a unionised labour market in a simple Diamond's OLG framework. Interesting findings, so far escaped closer scrutiny, emerge. Under some particular conditions about the key parameters of the model, the unionised-wage economy may perform better than...

We analyse the dynamics of an overlapping generations economy with unfunded pay-as-you-go public pensions and myopic expectations by comparing exogenous and endogenous fertility contexts. It is shown that large PAYG pensions may cause endogenous fluctuations in both cases. However, ceteris...

Recently Fanti and Gori (2008) showed – in the basic overlapping generations (OLG) model of neoclassical growth with exogenous fertility (Diamond, 1965) – that a positive relationship between longevity and pay-as-you-go (PAYG) pensions may exist independently of the size of the contribution...
