Developing a model in which heterogeneity arises among two groups of fundamentalists that follow gurus, we focus on the dynamic effects of increasing heterogeneity. We show that an increasing degree of heterogeneity leads firstly (i) to insurgence of a pitchfork bifurcation and, secondly (ii)...

Nel presente lavoro abbiamo costruito un modello di determinazione del tasso di cambio in presenza di agenti eterogenei (Banca Centrale, Investitori e Market Makers). Ampie fluttuazioni del tasso di cambio sono il risultato di dinamica endogena, in particolare scaturiscono dall’interazione...

Developing a model with a switching mechanism, we show how complex dynamics can be generated even though heterogeneity arises among agents with the same trading rules (fundamentalists). We assume that there are two experts which are imitated by other operators. We show that (i) market...

In this note, we propose a model where a quantity setting monopolist has incomplete knowledge of the demand function. In each period, the firm sets the quantity produced observing only the selling price and the slope of the demand curve at that quantity. Given this information and through a...

Il modello tradizionale di comportamento del consumatore è basato sull’ipotesi di razionalità, ovvero il consumatore effettua le proprie scelte massimizzando la funzione d'utilità soggetta al vincolo di bilancio. Questo approccio richiede che ogni consumatore abbia una completa conoscenza...

We propose a repeated oligopoly game where quantity setting firms have incomplete knowledge of the demand function of the market in which they operate. At each time step they solve a profit maximization problem by using a subjective approximation of the demand function based on a local estimate...

We consider a growth model proposed by Matsuyama [K. Matsuyama, Growing through cycles, Econometrica 67 (2) (1999) 335-347] in which two sources of economic growth are present: the mechanism of capital accumulation (Solow regime) and the process of technical change and innovations (Romer...
