When modelling 'social bads', such as illegal drug consumption, researchers are often faced with a dependent variable characterised by an excessive?amount of zero bservations. Building on the recent literature on hurdle and double-hurdle models, we propose a double-inflated modelling framework,...

We contribute to the existing literature on drug consumption by analysing the misuse of pharmaceutical drugs, which has attracted scant attention in the economics literature. Specifically, using individual level data, we explore the determinants of pharmaceutical drug misuse and focus on...

We introduce the (panel) zero-inflated interval regression (ZIIR) model, which is ideally suited when data are in the form of groups, which is commonly the case in survey data, and there is an ‘excess’ of zero observations. We apply our new modelling framework to the analysis of visits to...

We explore the determinants of financial satisfaction using a modelling framework which allows the drivers of financial satisfaction to vary across life stages. Given that financial satisfaction is measured as an ordered variable, our modelling approach is based on a latent class ordered probit...

We contribute to the small, but important, literature exploring the incidence and implications of mis-reporting in survey data. Specifically, when modelling ?social bads such as illegal drug consumption, researchers are often faced with exceptionally low reported participation rates. We propose...

This paper proposes a discrete-choice behavioural model of labour supply to examine the role of ill-health on single parents’ employment. The model provides estimates of individual preferences over a given set of labour market states and allows these preferences to be influenced by a measure...

Even in the face of a continuously changing economic environment, interest rates often remain unadjusted for long periods. When rates are moved, the norm is for a series of small unidirectional discrete basis-point changes. To explain these phenomena we suggest a two-equation system combining a...

We examine the dissent voting record of the Bank of England Monetary Policy Committee (MPC) in its first decade. Probit estimates indicate the impact of career experience on dissent voting is negligible, whereas the impact of forecast inflation is pronounced. In addition to finding a role for...
