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 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...

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 consider the estimation of the standard errors of individual-specific parameters calculated ex post from a non-linear random parameters model. Our key contribution lies in introducing a simple method of appropriately calculating these standard errors, which explicitly takes into account the...

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...

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,...

There is concern that workers are finding it increasingly difficult to balance work and family life and face growing time stress. Working from home is one form of flexibility in working arrangements that may assist workers to juggle work and non-work commitments. However, it may also provide a...

Western Australia is a diverse state with unique regions. Studies on the economy that adopt a ‘one size fits all’ approach’ are likely to be hindered by a lack of the richness and variability inherent in the intra-state regions. This paper proposes a modelling framework for the Western...

At any given instance there are many indicators of the state of the economy, or the state of a sector, and frequently the signals are mixed – some may point to an expansion, others to a contraction, for example. We consider how best to combine this conflicting information into an overall index...
