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...

This paper aims at investigating if the conventional wisdom, that a decrease in the degree of product differentiation (which implies increasing competition) always reduces firms’ profits, remains true in a differentiated duopoly model with decentralized, or firm-specific, monopoly unions. In...

Motivated by the recent decrease in the number of children experienced in many developed countries, in this paper we consider an OLG small open economy with endogenous fertility and human capital formation through public education and look at the role the government can play in affecting...

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...

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...
