We consider a single-period financial market model with normally distributed returns and the presence of heterogeneous agents. Specifically, some investors are classical Expected Utility Maximizers whereas some others follow Cumulative Prospect Theory. Using well-known functional forms for the...

We develop a learning rule that generalises the well known fading memory learning in the sense that the weights attached to the available time series data are not constant and are updated in light of the forecast error(s). The underlying idea is that confidence in the available data will be low...

We study a cobweb-type commodity market where n firms operate and characterised by a strictly monotone demand and supply. The firms are assumed to differ in a key parameter governing price expectations which we suppose to be adaptive. We characterise the unique steady state of the resulting...

The recent literature about the so called brain drain assumes that destination countries are characterized not only by higher wages than the source country, but also by a higher or at least not lower relative return to skill. As this assumption has a doubtful empirical validity, we assess...

We study a simple monetary model in which a central bank faces a boundedly rational private sector and has the goal of stabilizing inflation. The system’s dynamics is generated by the interaction of the expectations about inflation of the various agents involved. A modest degree of...

We build a model in which asset prices are expectationally driven and agents forecast future prices hinging on a combination of fundamental value, trend and inertia. The model has a unique steady state and we investigate its stability. In particular the amount of behavioural heterogeneity in the...

We analyse the capacity of a range of different learning rules to describe actual human behaviour in the experiment on expectation formation in a cobweb model conducted by Hommes et al. (2000). We find indication of a relative superiority in terms of descriptive capacity of forms of generalised...

The cobweb model literature has mostly overlooked the issue of firms' financial viability and the related question of market entry and exit. This paper tries to address these problems building an agent-based computational cobweb model with borrowing constraints and endogenous participation of...
