We investigate the consequences of using time-invariant individual effects in panel data models when the unobservables are in fact time-varying. Using data from the British Offending Crime and Justice panel, we estimate a dynamic factor model of the occurrence of a range of illicit activities as...

We construct linked register data on five Norwegian birth cohorts, covering: criminal charges after age 15; family characteristics and history up to age 15; and (for males) IQ test scores. A longitudinal analysis of the risk of initiation into crime in early adulthood suggests an increased risk for...

To measure poverty, incomes must be equivalized across households with different structures. In this paper, we use a very flexible ordered response model to analyze the relationship be- tween income, demographic structure and subjective assessments of financial wellbeing drawn from the 1991-2008...

We estimate the implicit disability costs faced by older people, using data on over 8,000 individuals from the UK Family Resources Survey. We extend previous research by using a more flexible statistical modelling approach and by allowing for measurement error in observed disability and standard...

We examine the effect of survey measurement error on the empirical relationship between child mental health and personal and family characteristics, and between child mental health and educational progress. Our contribution is to use unique UK survey data that contains (potentially biased)...

For many years the NHS has been subject to allegations that gender and racial discrimination are a feature of the internal labour market for qualified nurses. This paper examines this issue with regard to the promotion process using 1994 survey data. We start by rejecting the assumption of...

We provide a critical discussion of the concept drug-related crime and review methods for estimating its volume, emphasising the importance of an appropriately defined counterfactual. We then construct new estimates for England and Wales in 2003-6, combining data from the Arrestee Survey and...

We compare three major UK surveys, BHPS, FRS and ELSA, in terms of the picture they give of the relationship between disability and receipt of the Attendance Allowance (AA) benefit. Using the different disability indicators available in each survey, we estimate a model in which probabilities of...
