We study a procurement auction recently analysed by Gal-Or et al. (2007). In this auction game the buyer ranks different bids on the basis of both the prices submitted and the quality of each bidder that is her private information. We emphasise the similarity between this model and existing...

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...

Procurement auctions often involve quality considerations as a determinant of the final outcome. When qualities are the procurer’s private information then various information policies may be used to affect the expected outcome. For auctions with two cost heterogeneous suppliers, this work...

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 study a model of procurement auctions in which information policies can be used to treat two heterogeneous suppliers asymmetrically. The buyer is shown to be better off revealing information about her preferences to the weak supplier only, when there is a sufficient cost difference between...

This work studies a model of multidimensional auction in which a buyer needs to procure a given good from either of two potential suppliers whose quality is the buyer's private information and whose production costs are heterogeneous. Costs asymmetries constitute a novelty in this framework and...

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 procurement auction recently analysed by Gal-Or et al. (2007). In this auction game the buyer ranks different bids on the basis of both the prices submitted and the quality of each bidder that is her private information. We emphasise the similarity between this model and existing...

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...
