The Welfare Cost of Means-Testing: Pensioner Participation in Income Support

We estimate parametric and semi-parametric binary choice models of benefit take-up by British pensioners and develop methods, based on the compensating variation, of inferring the cash-equivalent value of disutility arising from stigma or complexity of the claims process, taking account of the self-selection induced by take-up. We extend this to incorporate the claim costs borne by welfare-recipients into the measurement of pensioner poverty. We find that allowing for implicit claim costs in this way has a non-negligible impact on poverty measurement.benefit take-up; program participation; pensions; welfare; poverty

DNA Sequence Determinants Controlling Affinity, Stability and Shape of DNA Complexes Bound by the Nucleoid Protein Fis.

The abundant Fis nucleoid protein selectively binds poorly related DNA sequences with high affinities to regulate diverse DNA reactions. Fis binds DNA primarily through DNA backbone contacts and selects target sites by reading conformational properties of DNA sequences, most prominently intrinsic minor groove widths. High-affinity binding requires Fis-stabilized DNA conformational changes that vary depending on DNA sequence. In order to better understand the molecular basis for high affinity site recognition, we analyzed the effects of DNA sequence within and flanking the core Fis binding site on binding affinity and DNA structure. X-ray crystal structures of Fis-DNA complexes containing variable sequences in the noncontacted center of the binding site or variations within the major groove interfaces show that the DNA can adapt to the Fis dimer surface asymmetrically. We show that the presence and position of pyrimidine-purine base steps within the major groove interfaces affect both local DNA bending and minor groove compression to modulate affinities and lifetimes of Fis-DNA complexes. Sequences flanking the core binding site also modulate complex affinities, lifetimes, and the degree of local and global Fis-induced DNA bending. In particular, a G immediately upstream of the 15 bp core sequence inhibits binding and bending, and A-tracts within the flanking base pairs increase both complex lifetimes and global DNA curvatures. Taken together, our observations support a revised DNA motif specifying high-affinity Fis binding and highlight the range of conformations that Fis-bound DNA can adopt. The affinities and DNA conformations of individual Fis-DNA complexes are likely to be tailored to their context-specific biological functions

The distributional impact of reforms to disability benefits for older people in the UK

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 withdrawal of AA/DLA. Despite their present non-means-tested nature, we show that withdrawal would affect mainly low-income people, whose losses could be mitigated if SDP were retained at its current or a higher level. We also show the importance of the method of describing distributional impacts and that use of inappropriate income definitions in official reports has overstated recipients' capacity to absorb the loss of these benefits

The take-up of multiple means-tested benefits by British pensioners. Evidence from the Family Resources Survey

Non take-up of means-tested benefits among pensioners is of longstanding concern. It will assume increased importance from 2003 with the introduction of the new means-tested Pension Credit, which will subsume Income Support and to which about half of all pensioners are expected to be entitled. In this paper we use Family Resources Survey data spanning the period April 1997 to March 2000 to investigate patterns of take-up of the three main means-tested benefits to which pensioners may be entitled – Income Support (IS), Housing Benefit (HB) and Council Tax Benefit (CTB). We find that although 36% of pensioners in our sample are failing to claim their entitlements to at least one of these benefits, only 16% of non claimants are failing to claim amounts worth more than 10% of their income. The proportions by which claiming all entitlements would increase non- claimants’ incomes are more useful indicators than individual benefit take-up rates, of the effectiveness of means-tested benefits. In general take-up is high where entitlement is high. But there are exceptions to this which may reflect the claims process and/or a greater degree of social stigma associated with IS than with HB or CTB.benefit take-up; pensions; means-testing; welfare participation

Disability and poverty in later life

This report explores the relationship between disability and poverty among the older population. It emphasises the additional living costs that disabled people face, and the importance of taking disability costs into account when making poverty assessments in the older population. The report considers alternative directions of reform for the system of public support for older people with disabilities and casts doubt on some of the suggestions that have been made for improving the targeting of public support for older disabled people
