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 estimate parametric and semi-parametric binary choice models of benefit take-up by British pensioners and use a revealed preference argument to infer the cash-equivalent value of disutility arising from stigma or complexity of the claims process. These implicit costs turn out to be relatively...

We propose a nonparametric matching approach to estimation of implicit costs based on the compensating variation (CV) principle. We apply the method to estimate the additional personal costs experienced by disabled older people in Great Britain, finding that those costs are substantial,...

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...

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...

The UK Disability Living Allowance (DLA) is a non-means-tested cash benefit claimable initially only by people under 65, but receipt of which can be continued after that age. The similar Attendance Allowance (AA) can only be claimed after age 65. Recent proposals for benefit reform have...
