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 analyse the results of experiments on aspects of the design of questionnaire and interview mode in the 2009 wave of the new UK Understanding Society panel survey. The randomised experiments relate to job- and life-satisfaction questions and vary the labeling of response scales, the mode of...

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...

The UK Attendance Allowance (AA) and Disability Living Allowance (DLA) are non means-tested benefits paid to many disabled people aged 65+. They may also increase entitlements to means-tested benefits through the Severe Disability Premium (SDP). We investigate proposed reforms involving...

 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)...

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 study the relationship between individuals’ participation in household panels, their health and employment states and the design of survey fieldwork procedures, using a comparative approach based on data from the UK BHPS and Australian HILDA Survey. We simulate the impact of...

This paper presents some preliminary findings from Wave 6 of the Innovation Panel (IP6) of Understanding Society: The UK Household Longitudinal Study. Understanding Society is a major panel survey in the UK. In March 2013, the sixth wave of the Innovation Panel went into the field. IP6 used a...

Factor rotation is widely used to interpret the estimated factor loadings from latent variable models. Rotation methods embody a priori concepts of 'complexity' of factor structures, which they seek to minimise. Surprisingly, it is rare for researchers to exploit one of the most common and...

We analyse the results of experiments on questionnaire design and interview mode in the first four waves (2008-11) of the UK Understanding Society Innovation Panel survey. The randomised experiments relate to job, health, income, leisure and overall life-satisfaction questions and vary the...
