Housing Subsidies and Work Incentives in Great Britain.

The relationship between housing costs, wages and transfer programmes is complex and yet plays an important part in determining the incentive to work for individuals in low income or high housing cost households. While it is true that many individuals who are in these categories are out of the labour force (retired, sick and disabled), there are many who are not and whose incentive to seek work, or to work harder if already in work, could be modified by directly changing the rent levels they face or indirectly via changes to the structure of programmes designed to subsidize housing for the poor. Here we estimate a static discrete choice labour supply model which allows for housing benefit programme participation. We use samples of 42491 married women and 13340 unmarried women drawn from Great Britain Family Resources Surveys 1994/5-97/8. We find that women are quite responsive to labour supply incentives, housing benefit income has similar incentive effects to earned income which suggests any "stigma" is small. Our analysis is complemented by simulating housing benefit and direct rent subsidy reforms.LABOUR ; HOUSING ; COSTS

The labor supply effect of in-kind transfers

We estimate a model of labor supply and participation in multiple programs for UK lone mothers which exploits a reform of in-work transfers. Cash entitlements increased but eligibility to in-kind child nutrition programs was lost. We find that in-work cash and in-work in-kind transfers both have large positive labor supply effects. There is, however, a utility loss from program participation which is estimated to be larger for cash than for child nutrition. This implies that the partial cash out of the in-kind benefits reduced labor supply.

There?s no such thing as a free lunch: Evidence of altruism and agency from household expenditure responses to child nutrition programs

Many countries provide transfers for particular client groups such as children and often such transfers are in-kind rather than cash. However, this may, at least partially, crowd out private expenditures on the goods in question because they reduce the incentive for other individuals, like parents, to make altruistic transfers. They are often made to one household member on behalf of another so there may also be agency concerns: the recipient may divert some of the transfer away from the intended beneficiary. This paper throws light on these issues using three nutrition programs for children in UK households: free lunch at school for children from poor households; free milk to poor households with pre-school children; and free milk at day-care for pre-school children in attendance regardless of parental income. We provide difference in difference estimates based on a welfare reform and on variation in the timing of school holidays. These estimates are broadly consistent with estimates of a structural model that is identified using the same welfare reform. This gives us confidence in the interpretation of our estimates that the structural model provides but the simple difference-in-difference cannot.

The implications of autoantibodies to a single islet antigen in relatives with normal glucose tolerance:development of other autoantibodies and progression to type 1 diabetes

AIMS/HYPOTHESIS: Autoantibodies directed at single islet autoantigens are associated with lower overall risk of type 1 diabetes than multiple autoantibodies, but individuals with one autoantibody may progress to higher risk categories. We examined the characteristics of this progression in relatives followed prospectively in the TrialNet Pathway to Prevention. METHODS: The study population comprised 983 relatives who were single autoantibody positive with normal baseline glucose tolerance (median age 16.2 years). Samples were screened for antibodies to GAD, insulinoma-associated antigen 2 (IA-2) and insulin, and all positive samples tested for antibodies to zinc transporter 8 and islet cell antibodies. RESULTS: Antibodies to at least one additional islet autoantigen appeared in 118 of 983 relatives (overall 5 year risk 22%, 95% CI [17.9, 26.1]). At baseline, antibodies to GAD alone (68%) were more frequent than antibodies to insulin (26%) or IA-2 (6%), but all were associated with a similar risk of developing additional autoantibodies. Risk was associated with younger age (p = 0.002) and HLA class II genotype, but was similar in high and intermediate genetic risk groups (p = 0.65). Relatives who became multiple autoantibody positive during the follow-up had increased risk of developing diabetes comparable with the risk in relatives with multiple autoantibodies at study entry. CONCLUSIONS/INTERPRETATION: Progression of islet autoimmunity in single autoantibody positive relatives in late childhood/adult life is associated with a predominance of autoantibodies to GAD and a distinct HLA risk profile. This heterogeneity in type 1 diabetes autoimmunity has potentially important implications for disease prevention.

Correction to "Long-term and recent changes in sea level in the Falkland Islands"

In the paper “Long-term and recent changes in sea level in the Falkland Islands” by P. L. Woodworth et al. (Journal of Geophysical Research, 115, C09025, doi:10.1029/2010JC006113, 2010), in paragraph 47 we adopted a value of −0.52 mm/yr for the estimated rate of present-day sea level change in the Falkland Islands due to glacial isostatic adjustment (GIA). This value was used to remove the contributions of GIA to our measurements of historical and recent rates of sea level change. However, it was based on a misreading of the data file of Peltier [2004] on the Permanent Service for Mean Sea Level Web site (http://www.psmsl.org/train_and_info/geo_signals/gia/peltier). More reasonable values to apply to the observed changes since the mid-nineteenth century and in recent years would be −0.69 and −0.61 mm/yr respectively. Consequently, the long-term rate of sea level change between 1842 and the early 1980s, after correction for air pressure effects and for GIA, reported as +0.75 ± 0.35 mm/yr in paragraphs 1, 47, 55, and 61 should be +0.92 ± 0.35 mm/yr, the corresponding rate between 1842 and the midpoint of recent data of 1.06 ± 0.22 mm/yr in paragraphs 48 and 55 should be 1.23 ± 0.22 mm/yr, and the corresponding rate since 1992 reported as 2.51 ± 0.58 mm/yr in paragraphs 1 and 52 becomes 2.60 ± 0.58 mm/yr. The middle of paragraph 63 becomes “The Stanley data suggest that the rate of change of sea level in East Falkland since 1992 has been approximately 2.6 mm/yr, a rate supported by information from satellite altimetry.” These small GIA model corrections have no bearing on the main findings of our paper on the difference in the rates of sea level change between the historical (1842 to present-day) and recent (last 2 decades) epoch

Child support reform: some analysis of the 1999 white paper

This paper uses a sample of lone mothers (and former lone mothers who are now repartnered) drawn from the 1997 Family Resources Survey to analyse the potential effects of reforming the UK system of Child Support. The main deficiency of the data is that non-resident fathers cannot be matched to the mothers in the data and this is overcome by exploiting information from another dataset which gives the joint distribution of the characteristics of separated parents. The effects of reforming the Child Support system is simulated for the amount of maintenance liabilities, the amount paid and the net incomes of households containing mothers with care and households containing non-resident fathers. The likely effects of the reform are simulated at various levels of compliance. The analysis highlights the need for further research into the incentive effects of Child Support on individual behaviour

Crustal strain in central Greece from repeated GPS measurements in the interval 1989-1997

A 66-station GPS network spanning central Greece, first observed in 1989, has been occupied fully on three occasions: June 1989, October 1991 and May 1993. Subsets of this network bounding the Gulf of Korinthos have also been occupied in June 1995, October 1995, May 1996 and September/October 1997. The first three occupations were processed using a fiducial GPS methodology, whereas later surveys were processed using CODE precise orbits. Combination of data from different surveys to yield smooth site velocities requires global network translations at each epoch to compensate for errors in the realization of the reference frame. This method provides a posteriori estimates of the relative coordinate errors and reference frame noise. Only one earthquake, the 1995 June 15 Egion event, has caused significant local coseismic displacement, and its effects on the interseismic velocity field are removed using an elastic dislocation model. We constrain the orientation of the 100 yr triangulation—GPS velocity estimates of Davies et al. (1997) using 14 sites common to the two networks. The goodness of fit of this transformation indicates that the short-term and 100 yr geodetic estimates of deformation are highly compatible. We infer that short-term geodetic studies are capable of determining longer-term deformation rates provided that transient, local effects can be modelled. From the combined velocity field, we estimate principal strains and rigid-body rotation rates at points on a regular grid using data from neighbouring sites. Strain rates are high within the Gulf of Korinthos and much lower elsewhere. The extension rate across the Gulf of Korinthos increases from east to west. Comparison of the extension rate with historical and recent rates of seismic release of strain reveals significant medium-term seismic hazard in the western Gulf of Korinthos, and may also indicate long-term aseismic strai

Transformative filmmaking in resettlement : refugees addressing acculturation gaps, concordance, and cohesion in Canada

This research looks at the potential of community film-making as an acculturation resource for use by resettling refugees. It explores the questions: How does participatory filmmaking affect intergenerational tension towards second-culture acquisition, and how does screening refugee-authored film affect community cohesion? The participants' reflections on the process of heritage re-mediation through oral history filmmaking and collective narrative are shared. Discussions throughout the development of Bhutanese refugee community-authored educational documentary evolve into this practice of refugees using video production to ease integration. Audiences also provide data to the research. It appears that CFAP creates opportunity to build bridges through heritage storytelling, to the host community’s social network resulting in trust and social inclusion. Simultaneously the process seems to help the refugee community by mitigating losses, and helping intergenerational relationships. The practice of Community Filmmaking for Acculturation Purposes is developed. The process appears to moderate acculturative family distancing, and enhance community cohesion
