A Zero Inflated Regression Model for Grouped Data
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... Read article
Estimating the Standard Errors of Individual-Specific Parameters in Random Parameters Models
Abstract 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 sampling variability... Read article
Work Incentives and Decisions to Remain in Paid Work in Australia
Introduction Lifting workforce participation rates is a key objective of Australian policy-makers. The most recent evidence of this emerged in the lead up to the 2013 Federal election. The Coalition proposed that young Australians unemployed for 12 months or more and receiving... Read article
Alternative Methods of Estimating Interaction Effects in Non-Linear Models
Introduction This paper reviews alternative methods for estimating interaction effects in non-linear models. Interaction effects refer to the way in which the relationship between two variables can differ between categories of a third variable. Many researchers attempt to measure interaction effects, understanding that... Read article
Elder Care and the Employment Intentions of Mature Age Women
Introduction This paper addresses the employment impacts of eldercare, which we define as the informal, uncompensated care provided to elderly people. This unpaid work is a vital component of the ‘care economy’ that utilises time, emotional and other resources of... Read article
Brain Drain or Brawn Drain?
Studies on the determinants of migration provide evidence that distance has a strong negative effect. That is, the farther the region is, the lower the probability that people would like to migrate to. However, Western Australia, whose capital city is... Read article
Modelling Illegal Drug Participation in Australia
Abstract 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 a... Read article
Trends in the Gender Wealth Gap Among Single Households in Australia 2002-2010
Abstract This study uses three wealth modules from the Household, Income and Labour Dynamics in Australia Survey to explore the gender wealth gap for single Australian households between 2002 and 2010. The findings indicate significant gender wealth gaps, which have increased over the... Read article
The Influence of Psychological Well-Being, Ill-Health and Health Shocks on Single Parents’ Labour Supply
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... Read article
Advantages of Non-Normality in Testing Cointegration Rank
Abstract Since the seminal work of Engle and Granger (1987) and Johansen (1988), testing for cointegration has become standard practice in analysing economic and financial time series data. Many of the techniques in cointegration analysis require the assumption of normality, which may... Read article
Econometric Modelling of Social Bads
Abstract When modeling “social bads”, such as illegal drug consumption, researchers are often faced with a dependent variable characterised by an “excessive” amount of zero observations. Building on the recent literature on hurdle and double-hurdle models, we propose a double-inflated modeling framework, where the... Read article
Underemployment among mature age workers in Australia
Underemployment is a serious and pervasive problem both in terms of its impact on those individuals affected, and for the economy as a whole. International research has found that those who experience periods of underemployment are more likely to have... Read article
