This paper shows that two societies differing because of the people's initial propensity to devote time and efforts to non-profit activities may never converge. This lack of convergence is interpreted as the tendency of the cultural values and attitudes dominant in each society to perpetuate...

We consider an organisation which has been allotted a fixed budget 'A' by higher authorities, for procuring certain specified items. It seeks price quotations from firms. The firm quoting the lowest price secures the contract to sell the item to the organisation. In this context we compare...

The aim of these lecture notes is to present a few mathematical facts about the bifurcations of nonlinear difference equations, in a concise and simple form that might be useable by economic theorists.

We study the implications of constant money growth rules on the stability properties of the equilibrium, in economies where the agents are subject to a partial cash-in-advance constraint applying simultaneously to consumption and investment purchases. By reference to similar models in which the...

In a setting with a risk-adverse union, we study the effects of central bank's political transparency on wage level and inflation volatility according to its degree of conservativeness. We obtain some results that contrast with these obtained in the same kind of model or in a Rogoff type model...

Firms raise cost-reducing alliances before competing with each other, but cannot fully appropriate the shared knowledge. When spillovers disseminate through the network of alliances, link formation enables firms to capture more spillovers, but by doing so they become intermediary in the...

This paper examines the role of the labour share in creating instability in a small open economy. We assume that financial markets are imperfect so that entrepreneurs are credit constrained, and that this constraint is tighter for low levels of financial development. Aghion, Bacchetta and...

A dynamic three-stage game is modelled to analyse the capacity choice in a mixed oligopoly with private leaders and a public follower. To distinguish long-term and short-term market power, I consider two stages of investment, the first by a private firm and the second by a public one, and one...
