The Analysis of Poverty Data with Endogenous Transitions*

It is common to analyse poverty data broken down by household or economic status. Implicitly, it is assumed that people change state (for example, single, married, children, no children) for exogenous reasons. If we bring economic behaviour into the problem, then such transitions become endogenous. The data are then insufficient to identify the claims made from them. The distribution of the characteristics of the individuals in the states will be endogenous, and the state average poverty rate will depend on the composition of the individuals in the state as well as on the economic impact of being in that state per se. In this paper, we set out a simple model with endogenous transitions to make our point, and apply this to Family Expenditure Survey data for Britain. We show that our argument has empirical content for Britain.     

The Impact of a Conditional Cash Transfer Programme on Consumption in Colombia*

This paper studies the impact of a conditional cash transfer programme in Colombia on the total consumption of very poor households and on its components. Our evaluation methodology involves comparing household expenditures in areas in which the programme was not implemented (control) and those in which it was (treated). We use a quasi‐experimental approach, as the Familias en Acción programme was not randomly assigned across localities, for political reasons. We condition on a large range of household‐ and municipality‐level characteristics, and also control for pre‐programme differences in the outcomes of interest using a differences‐indifferences methodology. We find that the programme has been effective at greatly increasing total consumption and its main component, food consumption, in both rural and urban areas. The programme has also contributed to improvements in the quality of food consumed, in particular of items rich in proteins (milk, meat and eggs) and of cereals. Furthermore, the programme has created redistributive effects in favour of children through expenditure on education and children's clothing, while it has not significantly affected consumption of adult goods such as alcohol and tobacco or adults’clothing.     

Health status and portfolio choice: Causality or heterogeneity?

This paper explores the role of unobserved individual characteristics in the health-assets and health-portfolio correlations. We apply various econometrics models to a unique longitudinal dataset with rich information that allows for the exploitation of four different health indices. Our findings show strong cross-sectional correlations between health and both financial and non-financial assets, but these correlations seem to be mainly driven by heterogeneity as the correlations largely disappear in the fixed-effects model. Adverse health shocks, however, are found to motivate a safer portfolio choice even after individual fixed-effects are controlled for – a result consistent with the prediction made by the background risk theory. Our findings suggest that health shocks shift investment from risky assets toward other financial assets, but keep the total financial assets unchanged.     

Public Support for Older Disabled People: Evidence from the English Longitudinal Study of Ageing on Receipt of Disability Benefits and Social Care Subsidy

In England, state support for older people with disabilities consists of a national system of non‐means‐tested cash disability benefits and a locally administered means‐tested system of social care. Evidence on how the combination of the two systems targets those in most need is lacking. We estimate a latent factor structural equation model of disability and receipt of one or both forms of support. The model integrates the measurement of disability and its influence on receipt of state support, allowing for the socio‐economic gradient in disability, and adopts income and wealth constructs appropriate to each part of the model. We find that receipt of each form of support rises as disability increases, with a strong concentration on the most disabled, especially for local‐authority‐funded care. The overlap between the two programmes is confined to the most disabled. Less than half of recipients of local‐authority‐funded care also receive a disability benefit; a third of those in the top 10 per cent of the disability distribution receive neither form of support. Despite being non‐means‐tested, disability benefits display a degree of income and wealth targeting, as a consequence of the socio‐economic gradient in disability and likely disability benefit claims behaviour. The scope for improving income/wealth targeting of disability benefits by means testing them, as some have suggested, is thus less than might be expected.     

Means Testing and Retirement Choices in Europe: A Comparison of the British and Danish Systems*

We develop a simulation model of household behaviour in which both the consumption/saving and labour/leisure choices are endogenous. This model is used to explore the effects of the UK and Danish state tax and benefit systems on the labour supply of workers aged 50 or over. We find that, in broad terms, differences in labour force participation can be accounted for by differences in benefit structures. Furthermore, our simulations suggest that the UK system is preferred by young people while the Danish arrangement – which imposes a larger tax burden and provides larger welfare benefits – is chosen by people of 50 or older. Notably, people older than 60 are in the majority in the simulated population. The Danish system does not promote notably greater equality over the lifetime, but it does underpin a higher level of consumption for people of 50 or older.     

What's on the Menu? Policies to Reduce Young People's Sugar Consumption

Young people in the UK consume far above the maximum recommended levels of added sugar. It is likely that neither they nor their parents fully take account of the future health, social and economic costs of this high sugar consumption. This provides a rationale for policy intervention. The majority of young people's added sugar consumption occurs in the home, where purchases are typically made by parents. This means that understanding the purchase decisions of adults is important for policy design, even if the policies aim to reduce the consumption of young people. We discuss the merits of popular policies, including taxes, advertising restrictions and restrictions on the availability of specific foods, and we identify promising avenues for future research.     

The impact of consumer behavior on financial security of households in Poland

The paper applies the concept of identity to investigate whether consumer behavior matters for a household's financial security. It is assumed that considerable part of households may express their identity through status-oriented consumption. The research is carried out in two steps. First, the index of financial security is built and used to determine the level of financial security experienced by working-age families in Poland. Second, the simulation results based on an econometric model are employed to find the answer to the question: Does financial insecurity result more from the need to manifest consumption at the higher level than average in an income-group of which people are members, or people want to be distinguishable inside their own income-group but they do not identify with a group having consumption at visibly higher level, or from the need to improve self-image by bringing own consumption closer to the pattern of a group with higher wealth status of which they are not members? The source of data is the 2005-2009 Households Budget Surveys in Poland. The findings offer empirical evidence for the relevance of consumer behavior for financial security of households in Poland. Considerable part of households expresses identity through conspicuous consumption. Both groups of households, the insecurity rich and the insecurity poor, accept the same ranking of status goods: a car on the first position, next homes (housing and equipment) and clothes on the third place. Status-oriented consumption creates life beyond means and pushes even relatively rich households towards financial insecurity.     

Higher Education Finance in the UK*

The introduction of top‐up fees for home‐domiciled undergraduate tuition in England from 2006–07 – and their planned increase in 2012–13 – raises important issues for university funding in Scotland, since it abolished tuition fees for Scottish and EU students in 2000–01. This paper focuses on what the increase in resources directed at English universities arising from top‐up fees means for the relative funding of English and Scottish undergraduates. Widely‐used funding‐per‐head figures do not provide an accurate picture of home‐ and EU‐domiciled undergraduate funding, as they include funding for research, postgraduate degrees and overseas students. The empirical work of this paper focuses on creating a consistent series of funding per full‐time equivalent undergraduate over time for England and for Scotland, stripping out funding for research, non‐EU students and postgraduate degrees to create a more accurate picture of the funding gap between the two countries. It also takes into account the different composition of undergraduate degree subjects taken in England and Scotland. The findings indicate that the apparent historical advantage in funding per head in Scottish institutions compared with English ones has been largely driven by compositional differences: Scotland has a high proportion of medical, science and engineering undergraduates – subjects that command greater funding due to their relative complexity to teach. The top‐up fee introduced in 2006–07 brought funding per head in England to a level similar to that experienced in Scotland, and the future increase will result in funding per head in England outstripping that in Scotland by some magnitude. This suggests that the funding of Scottish students will fall significantly behind that of English students unless additional new sources of public or private funding for nScottish universities are found.     

Social security in the UK under New Labour: what did the Third Way mean for welfare reform?

In 1997, the Labour Party was elected in the UK with few explicitly articulated ideas about social security reforms. This paper reviews the large number of subsequent reforms to social security, and argues that some consistent themes have emerged. A commitment to keep to the tight spending plans of the previous, Conservative, administration left little scope for increases in benefit spending during the first two years in office. Since that time, increases in the generosity of some social security programmes have been directed towards achieving certain goals. An emphasis on encouraging paid work has been a consistent theme, whilst aims of reducing poverty rates for children and pensioners have been emphasised since 1999. Spending to achieve these goals has often been directed through means‐tested programmes, and there has been a related weakening of the link between paid National Insurance contributions and benefit entitlements. It remains to be seen whether reforms to the process of income assessment will increase take‐up.     

Poverty,Preference or Pensioners? Measuring Material Deprivation in the UK*

Indicators of material deprivation are typically based on a two-part question, asking, first, whether respondents possess a series of deprivation items and, second – if they do not – whether this is because of a lack of resources or is by choice. This second subquestion, or ‘enforced lack’ criterion, is ubiquitous but its efficacy has been questioned by a number of authors. In an important critique published in Fiscal Studies, McKay (2004) claimed that older people were more likely than younger respondents to report that they did not want the items they lacked, despite their lower incomes, and also that the enforced lack criterion introduced a subjectivity which, in effect, required respondents to feel poor in order to be classified as such. This critique has potentially profound implications for poverty measurement. In this paper, we seek to address the question of whether, if we are to employ indicators of material deprivation for poverty measurement, we should include the enforced lack criterion or not. In seeking to answer this question, we draw on data from the British Household Panel Survey (BHPS) and present tests of reliability and validity on indices of material deprivation, with and without the enforced lack criterion. Using odds ratio and analysis of variance methods, we find that the inclusion of the enforced lack criterion provides a measure of material deprivation which is both more reliable, and more valid based on a subjective measure of deprivation as well as on a majority of more objective forms of deprivation. Amongst the remaining minority (ill health for both methods and income quintile for the analysis of variance method), the divergent results can be explained, at least in part, by the older age profile of respondents in poor health and on low incomes. Thus, while there are legitimate concerns about the performance of such deprivation indicators amongst certain subgroups – in particular, amongst older people – on aggregate the enforced lack criterion helps to distinguish between poverty and preference.     

Removing Homeownership Bias in Taxation: The Distributional Effects of Including Net Imputed Rent in Taxable Income

The income tax systems of most countries entail a favourable treatment of homeownership, compared to rental‐occupied housing. Such ‘homeownership bias’ and its consequences for a wide range of economic outcomes have long been recognised in the economic literature. Although a removal of the homeownership bias is generally advocated on efficiency grounds, its distributional implications are often neglected, especially in a cross‐country perspective. In this paper, we aim to fill this gap by investigating the first‐order effects, in terms of distribution of income and work incentives, of removing the income tax provisions favouring homeownership. We consider six European countries – Belgium, Germany, Greece, Italy, the Netherlands and the UK – that exhibit important variation in terms of income tax treatment of homeowners. Using the multi‐country tax benefit model EUROMOD, we analyse the distributional consequences of including net imputed rent in the taxable income definition that applies in each country, together with the removal of existing special tax treatments of incomes or expenses related to the main residence; thus, we provide a measure of the homeownership bias. We implement three tax policy scenarios. In the first, imputed rent is included in the taxable income of homeowners, while at the same time existing mortgage interest tax relief schemes and taxation of cadastral incomes are abolished. In the two further revenue‐neutral scenarios, the additional tax revenue raised through the taxation of imputed rent is redistributed to taxpayers, through either a tax rate reduction or a tax exemption increase. The results show how including net imputed rent in the tax base might affect inequality in each of the countries considered. Housing taxation appears to be a promising avenue for raising additional revenues, or lightening taxation of labour, with no inequality‐increasing side effects.     

Public education reform: Community or national funding of education?

I use a political economy model of public funding of education to evaluate the welfare implications of a move from a community- to a nation-wide funding policy. Broadening the scope of education finance has intragenerational redistribution effects as well as intergenerational effects. Previous studies have emphasized the intragenerational redistribution effects of moving from local to state-financed systems, while holding factor prices fixed. The model in this paper includes a social security system and allows factor prices to vary endogenously. I examine the welfare effects of broadening the scope of financing from a community- to a nation-wide system and find that there are very large welfare gains as voters “internalize” the effect of the education policy on both factor prices and social security benefits. I also focus on the intergenerational distributional effects, finding that significant welfare gains occur despite the displacement of the median voter to an older agent that cares less about children's well-being.     

Returns to Skills and the College Premium

A substantial literature documents the evolution of the college premium in the U.S. labor market over the last 40 years or so. There are at least three different interpretations of this fact: (i) shifts in the relative supply of and demand for college versus high school labor, (ii) shifts in the relative supply of and demand for skills in the college versus high school sector, and (iii) composition effects. We investigate how each of these components contributes to the dynamics of the college premium and find that all three play a role, but the increase in the college premium is primarily driven by the first component. We also find that during the 1980s, the college premium for high school workers diverged from the college premium for college workers and a substantial fraction of the gap that opens up is primarily due to the increase in the returns to cognitive skills.     

Household portfolio choices,health status and health care systems: A cross-country analysis based on SHARE

Health risk is increasingly viewed as an important form of background risk that affects household portfolio decisions. However, its role might be mediated by the presence of a protective full-coverage national health service that could reduce households’ probability of incurring current and future out-of-pocket medical expenditures. We use SHARE data to study the influence of current health status and future health risk on the decision to hold risky assets, across ten European countries with different health systems, each offering a different degree of protection against out-of-pocket medical expenditures. We find robust empirical evidence that perceived health status matters more than objective health status and, consistent with the theory of background risk, health risk affects portfolio choices only in countries with less protective health care systems. Furthermore, portfolio decisions consistent with background risk models are observed only with respect to middle-aged and highly-educated investors.     

Gender implications of current social security reforms

This paper examines some current reforms to social security benefits / tax credits and changes to employment provisions from a gender perspective. It analyses tensions between the trend towards ‘individualisation’ and growing emphasis on the couple/household as a policy focus. New tax credits change the distribution of resources within many couples. Incentives to work for some second earners should improve; but extending in‐work subsidies to childless couples raises questions. Payment of child tax credit to the ‘main carer’ has been welcomed, though the implications of joint ownership of tax credits are unclear, and joint assessment will be extended. Many claimants' partners can now access employment services. However, this is aimed at reducing the number of workless households rather than expanding individuals' opportunities. Joint claims for jobseeker's allowance, and work‐focused interviews, involve increased responsibilities for partners but no right of access to individual income. A more consistent critical analysis of reform from a gender perspective is required.     

Who gets credit after bankruptcy and why? An information channel

Conventional wisdom holds that individuals find it difficult to obtain new credit post-bankruptcy. Using credit bureau data, we test this hypothesis and show that more than 90% of bankrupt individuals receive credit shortly after filing. Individuals with good credit history prior to filing have reduced credit availability after bankruptcy while those with ex-ante low credit quality receive more credit. We show that credit supplied to low quality individuals is severely curtailed during the financial crisis. We also find that the default probability on new debt increases after bankruptcy, especially among individuals with high ex-ante credit score. These findings are consistent with an information channel, in which bankruptcy reveals new information about a borrower’s credit quality.     

Universal Credit: A Preliminary Analysis of Its Impact on Incomes and Work Incentives*

Alongside a series of cuts that will reduce welfare spending by £18 billion per year by 2014–15, the UK government announced in November 2010 plans to integrate and simplify means‐tested welfare benefits and in‐work tax credits for working‐age adults into a single programme, to be known as Universal Credit and to be phased in from October 2013. The aims were to make it easier for claimants to claim benefits, to make the gains to work more transparent and to reduce the amount spent on administration and lost in fraud and error. More households will see entitlements rise from the move to Universal Credit considered in isolation than will see entitlements fall; in aggregate, entitlements will rise by nearly £1.1 billion a year. Low‐income families will see their entitlements rise by more than high‐income families, on average, and couples will gain more from the reform, on average, than single‐adult families, especially if there are also children in the family. In general, those facing the weakest incentive to work at all, or the weakest incentive to increase earnings, see their incentives strengthened, including those with very low earnings and hours worked per week and those who at present experience simultaneous withdrawal of multiple means‐tested benefits and tax credits. But a Council Tax Benefit that operates separately from Universal Credit, and that has rules that vary across English local authorities, could easily undermine many of the supposed advantages of Universal Credit.     

On optimal unemployment compensation

The design of an optimal unemployment compensation scheme is analyzed, using a dynamic principal-agent relationship between a risk-neutral planner (the principal) and risk-averse workers (the agents), where the planner's inability to observe workers’ job-search efforts creates a moral hazard problem. To design an implementable scheme, we require that each agent is guaranteed a minimum level of expected discounted utility, regardless of his past history. In contrast with previous studies, we find that the optimal contract is quite close to actual unemployment compensation schemes, both qualitatively and quantitatively.     

Poor Kids: trends in Child Poverty in Britain, 1968–96

According to Family Expenditure Survey (FES) data, child poverty (with a poverty line defined at half mean equivalised household income) has risen markedly in Britain in the last 30 years. By 1995–96, around one in three - or 4.3 million - children were living in poor households. This compares with child poverty rates of one in ten, corresponding to 1.4 million children, in 1968. The employment position of the household is seen to be important, with over half of poor children in 1995–96 living in households with no adults in work. If an absolute, rather than a relative, poverty line is utilised, child poverty remains stagnant since the late 1970s, following a period of rapid decline from 1968, despite considerable rises in average living standards. This reveals that the income position of households with children has been falling relative to that of childless households over time. Finally, looking at expenditure patterns and comparing their trends with income-based poverty measures tends to reinforce these findings.     

Supply-side reforms and learning dynamics

This paper studies the nature, the magnitude and the length of the transition after a capital tax cut. The transition is analysed with adaptive learning, under which agents do not need to adjust instantaneously to the change, as with rational expectations (RE). Impulse response analysis reveals that the transition with learning is asymmetrically sensitive to the nature of the exogenous technological shock at the time of the reform. If the reform coincides with a negative shock, the transition to the new steady state is slow, whereas, if it coincides with a positive shock, it is approximately the same as the one predicted by RE. The results imply that cutting capital income taxes before or during a recession may not be an effective means for short-run fiscal stimulus.
