Housing markets are subject to many interrelated sources of instability on both a microeconomic and macroeconomic scale. Housing decisions of different individuals will be interdependent, generating non-linearities, discontinuities and feedback effects. This paper focuses in on some behavioural...

Confirmation bias refers to cognitive errors that bias one towards one's own prior beliefs. A vast empirical literature documents its existence and psychologists identify it as one of the most problematic aspects of human reasoning. In this paper, we present three related scenarios where...

The literature on informational cascades and herding theory has for a decade focused on the externality and suboptimal outcomes generated from decision-making when spaces are coarser than private information spaces. Much of the output has therefore been positive, not normative. This paper...

This paper considers the impact of reviewers on the sale of a product of unknown quality. Sales occur simultaneously after an initial review by an unbiased, pessimistic or optimistic reviewer and we examine the impact on sales in each case. We find that counter-intuitively a pessimistic reviewer...

Experience gained in a workplace characterised by decision-making and learning-by-doing is modelled via a process of signal accumulation under several different frameworks. We initially look at the probability of success based on uninterrupted signal accumulation, then consider the impact of...

The standard simple sequential herding model is altered to allow a firm with a new product to have it reviewed publicly before launch. Reviewers are either inherently pessimistic, optimistic or unbiased. We find the counter-intuitive result that a firm with a good product will prefer a...

We extend the experimental literature on Bayesian herding using evidence from a financial decision-making experiment. We identify significant propensities to herd increasing with the degree of herd-consensus. We test various herding models to capture the differential impacts of Bayesian-style...

While much of the literature on cross section dependence has focused mainly on estimation of the regression coefficients in the underlying model, estimation and inferences on the magnitude and strength of spill-overs and interactions has been largely ignored. At the same time, such inferences...

We study the role played by geographical distance in the peering decisions between Internet Service Providers. Firstly, we assess whether or not the Internet industry shows clustering in peering; we then concentrate on the dynamics of the agglomeration process by studying the effects of...

This paper o¤ers a bridge between the theoretical literature on endogenous network formation and the empirical work on the impact of social networks on economic performance. We provide a theoretical framework of endogenous network formation that yields testable predictions for the network...
