Recent theoretical developments relating to investment under uncertainty have highlighted the importance of irreversibility for the timing of investment expenditures and their expected returns. This has subsequently stimulated a growing empirical literature which examines uncertainty and...

The failure of models of aggregate consumption to predict the consumer expenditure boom in the late 1980s is well- documented. This has generated a large theoretical and empirical literature in an attempt to refine our understanding of aggregate consumer spending behaviour. In this paper we...

This paper augments the Granger and Lee (Journal of Applied Econometrics, 4, 1989) non-symmetric error (equilibrium) correction model to assess the possibility that, in the aggregate, consumers respond differently to different types of disequilibrium error. This idea is illustrated using an...

This article examines whether subjective expectations of unemployment are reliable indicators of the probability of becoming unemployed and investigates their association with wage growth. We find that workers' fears of unemployment are increased by their previous unemployment experience and by...

This paper focuses on the determinants of aggregate investment spending in the UK, for the industrial and commercial company (ICC) sector. Important focal points of our analysis are the role for real profits and the impact of irreversibility and uncertainty in determining aggregate investment...

This paper develops an empirical model of the relationship between road traffic accidents and traffic flows. The analysis focuses on the accident externality, which is determined mainly by the difference between the marginal and average risks. The model is estimated using a new data-set which...
