How Consistent is Respondent Behaviour to Allow Linkage to Health Administrative Data over Time?

Abstract: This study constitutes the first longitudinal exploration of consent to link survey and administrative data. It relies on a theoretical framework distinguishing between passive, active, consistent and inconsistent consent behaviour. The findings show that, in general, consent behaviours are both passive and consistent. First, consent rates indicate that most respondents behave consistently over time. Secondly, the regression analyses show that for the majority of respondents, consent is not driven by personal convictions but rather depends on the circumstances of the respondent at the time of the interview and on the impact of the interviewers. The findings also show that in longitudinal surveys cross-sectional analyses of consent can be misleading. The changes in the magnitude and in the significance of the results when the temporal dimension of consent is taken into account is a clear indication that consent should be treated as a dynamic phenomenon.

Abstract: This study expands our knowledge of consent in linking survey and administrative data by studying respondents’ behaviour when consenting to link their own records and when consenting to link those of their children. It develops and tests a number of hypothesised mechanisms of consent, some of which were not explored in the past. The hypotheses cover: parental pride, privacy concerns, loyalty to the survey, pre-existing relations with the agency holding the data, and interviewer effects. The study uses data from the longitudinal Millennium Cohort Study to analyse the correlates of consent in multiple domains (i.e. linkage of education, health and economic records). It relies on a multivariate probit approach to model the different consent outcomes, and uses fixed and random effects specifications to estimate the effects of interviewers.The findings show that respondent’s behaviour vary depending on the consent domain (i.e. education, health, and economic records) and on the person for whom consent is sought (i.e. main respondent vs. cohort member). In particular, the cohort member’s cognitive skills and the main respondent’s privacy concerns have differential effects on consent. On the other hand, loyalty to the survey proxied by the longitudinal response history has a significant and strong impact on consent irrespective of the outcome. The findings also show that interviewers account for a large proportion of variations in consent even after controlling for the characteristics of the interviewer’s assignment area. In total, it is possible to conclude that the significant impact of some of the correlates will lead to sample bias which needs to be accounted for when working with linked survey and administrative data.

Abstract: The 1970 British Cohort Study (BCS70) is a continuing multi-purpose, multidisciplinary longitudinal study based on a sample of over 17,000 babies born in England, Wales and Scotland in 1970. The study has collected detailed information from the cohort members on various aspects of their lives, including their family circumstances at birth, education, employment, housing and partnership histories. There have been nine sweeps of data collection so far: at birth and at ages 5, 10, 16, 26, 30, 34, 38 and most recently age 42 (2012). This paper studies the extent of attrition in BCS70 and how it affects sample composition over time. We examine the determinants of response then construct inverse probability weights. In the last section, we use a simulation study to illustrate the effectiveness of weights and imputations in dealing with unit non-response and item missingness respectively. Our findings show that when the predictive power of the response models is weak, the efficacy of non-response weights is undermined. Further, multiple imputations are effective in reducing the bias resulting from item missingness when the magnitude of the bias is high and the imputation models are well specified.

Abstract: In an ageing society such as the UK, there is much interest in factors which can contribute to the wellbeing of older adults. It is not implausible to suppose that participation in learning could have beneficial effects, yet most research on the wider benefits of learning has tended to focus on young people or those in mid-life and there is currently rather little evidence on the impact of learning on the wellbeing of older adults. Insofar as evidence does exist, most of it is qualitative, and while of much value and interest, it is based on very small, and possibly not very representative, samples of the older population. This research aimed to provide new, quantitative evidence drawing on a large, nationally representative sample, on the effects of participation in learning on the wellbeing of older adults.

Trends in job quality in Europe.

Abstract: This study measures job quality in the 27 countries of the European Union, as well as the seven additional countries in Europe that participated in the European Working Conditions Survey (EWCS). Four indices were constructed for the study: earnings, prospects, intrinsic job quality and working time quality. The four indices cannot be reduced into a single index of job quality because associations between them are weak, and none can increase over time nor move in similar directions. They are, however, theoretically and conceptually coherent.

The intention was to fi nd an objective means of assessing the principle established in a number of EU directives that work should adapt to the workers. The indices constructed for this study do not rely on subjective measurement such as preferences and attitudes, but are built on the self-reported features of jobs that are associated with workers’ well-being.

Measuring the Impact of Universal Pre-School Education and Care on Literacy Performance Scores.

Abstract: The objective of this paper is to simulate the effects of universal pre-school education and care (PSEC) on reading performance scores and educational inequalities in the UK and Sweden. We utilize the PISA 2009 data and start by estimating a fixed effects multilevel model for each country in order to determine the returns to PSEC attendance. Then we simulate the effects of universal PSEC provision using counterfactual data. More precisely, after estimating the multilevel model, we progressively universalize PSEC participation starting with the lowest economic, cultural and social status (ESCS) decile and moving up to reach the top decile. At each stage of the universalisation process we compute the average predicted performance scores for each ESCS decile and for each country as well as their dispersions. This allows us to measure the change in average predicted literacy scores and the change in the level of inequality.

Our findings show that all social groups benefit from universalizing PSEC with the lowest groups getting the highest additional benefits from universalisation. Further, the international rankings of both Sweden and the UK improve after the universalisation of PSEC. The UK moves 12 positions up the OECD league table and Sweden moves up seven positions. We also find that inequalities in test scores drop until reaching a minimum when the lower seven ESCS deciles are attending PSEC and then starts to increase again. In conclusion, our findings clearly show that universalising PSEC would be an effective policy instrument that boosts educational performances while reducing inequalities in their distribution.

Pre-School Education and Care – a ‘Win-Win’ Policy?

November 2011

With Andy Green

LLAKES Research Paper N° 32.

Dowload the article in PDF

Abstract: Pre-school education and care (PSEC) is often claimed as a ‘win-win’ policy which simultaneously enhances both economic competitiveness and social cohesion. High levels of PSEC are said to raise living standards by increasing female employment rates and improving young people’s skills and to mitigate inequalities by reducing social gaps in learning outcomes. Much of the evidence for this rests on analysis of data for a small number of countries. In this paper we test the claims using cross-national time series data for a large number of OECD countries. The analysis of determinants of employment rates, using a variety of controls, does confirm the association between PSEC participation levels and female employment rates. However, the cross-national analysis does not support the argument that raising aggregate levels of PSEC participation necessarily reduces social gaps in attainment at 15 years of age. Participation in PSEC increases educational performance at 15 by similar amounts for children of all social groups in most countries. Social gaps in performance at 15 may only be mitigated by high levels of PSEC provision where children from less advantaged families get more – or better quality – provision. The recently announced Department for Education plan to extend free provision of PSEC for fifteen hours a week to two-year-old children from disadvantaged families (i.e. in care or qualifying for free school meals) therefore points in the right direction. However, it remains to be seen whether this will bias participation towards this group sufficiently to reduce inequalities in learning outcomes.

The Meso-Social Benefits of Vocational Education and Training for Social Groups and Communities

June 2011

Report for CEDEFOP

Dowload the article in PDF

Abstract: This report for CEDEFOP considers the meso-social benefits for social groups and communities. This is a subject of considerable interest both academically in terms of the contribution of Vocational Education and Training at the community level, and in policy terms, as agendas in European countries are orientated towards community cohesion and active, participatory citizenship.
This report can be contextualised in terms of a long history of VET as being implicated in mitigating against the disruption of community due to changes in economy and society. Indeed, the focus on community, social groups and VET has been long standing, arising from major shifts in the nature of the global economy in the 21st century from an industrial to a knowledge based economy.
We consider that VET has two benefits for groups at the meso-level being social capital formation and psycho-social benefits (group identity and quality of life). We also consider that the benefits of VET might accrue differently to different social groups on the basis of characteristics such as income, gender, household type and citizenship.
We would expect people who engage in VET to benefit differentially according to their membership of different social groups. In this report we look at the differential benefits for social groups and communities. For quantitative purposes the five social groups identified are: income groups, gender, household type, citizenship (nationals, EU nationals, and nonnational), and birth place groups.

Endogeneity Problems in Multilevel Estimation of Education Production Functions: an Analysis Using PISA Data.

LLAKES Research Paper N° 14.

Dowload the article in PDF

Abstract: This paper explores endogeneity problems in multilevel estimation of education production functions. The focus is on level 2 endogeneity which arises from correlations between student characteristics and omitted school variables.We first develop a theoretical model in order to show that school and peer characteristics are the by-product of student background. This theoretical framework helps the identification of the hypotheses we would like to test within the empirical part. From an econometric point of view, the correlations between student and school characteristics imply that the omission of some variables may generate endogeneity bias. Therefore, in the second section of the paper, an estimation approach based on the Mundlak (1978) technique is developed in order to tackle bias and to generate consistent estimates.The entire analysis is undertaken in a comparative context between three countries: Germany, Finland and the UK. Each one of them represents a particular system. For instance, Finland is known for its extreme comprehensiveness, Germany for early selection and the UK for its liberalism. These countries are used to illustrate the theory and to prove that the level of bias arising from omitted variables varies according to the characteristics of education systems.

Abstract: In this paper we assess the different definitions and theories of economic competitiveness at the firm and national levels. First we contrast the theories of classical liberal economists with those of the German historical school of national economics, noting the importance of the historical school for theories of national economic competitiveness. Drawing on the comparative political economy literature on ‘varieties of capitalism’, we then discuss the factors underlying competitiveness in social market economies, social democratic economies, and liberal economies.These models of capitalism are compared under six headings: labour markets and labour market institutions; financial markets; corporate funding and governance; inter-firm relations; the role of the state; and economic culture and history. In the penultimate section of the paper we discuss how the different models of capitalism have responded to the economic crisis and the impact of the crisis on their economic competitiveness. The paper concludes with a summary of the key points to emerge from the analysis and looks to how the scene may evolve as national economies begin to adapt.

The Anatomy of Inequalities in Educational Achievements: An International Investigation of the Effects of Stratification.

LLAKES Research Paper N° 3.

Dowload the article in PDF

Abstract: This paper analyses the mechanisms of stratification and inequalities in achievements. The main objective is to determine how stratification leads to unequal educational outcomes and how inequalities are channelled through student characteristics, school characteristics and peer effects.

On the one hand, a descriptive analysis is used to shed light on the education systems of the five selected countries and to provide insight into the functioning of stratification. The countries are Japan, the UK, Italy, Germany and Finland, and the dataset used is PISA 2003. On the other hand, a multilevel econometric model is elaborated in order to quantify the effects of student, school and peer characteristics on performance scores. The results on the regressions are then interpreted according to the institutional context of each country. In the last section, policy implications, based on the regression results, are derived.

Educational Quality, Communities, and Public School Choice: a Theoretical Analysis.

With Said Hanchane.

 

Dowload the article in PDF

Abstract: In this paper, we develop a multicommunity model where public mixed finance and private schools coexist. Students are differentiated by income, ability and social capital. Schools maximize their profits under a quality constraint; the pricing function is dependent on the cost of producing education and on the position of an individual relatively to mean ability and mean social capital. Income plays an indirect role since it determines the type of schools and communities that can be afforded by a student given his ability and social capital.

Three dimensional stratification results from schools’ profit maximization and individuals’ utility maximization. We study majority voting over tax rates; property tax is used to finance education not only in pure public schools but also in mixed finance schools. We provide the necessary conditions for the existence of a majority voting equilibrium determined by the median voter. Finally, we analyze the consequences of introducing public school choice.

Abstract: In this paper, we analyze the equilibrium on the market for schooling where both public and private schools coexist and where individuals are differentiated by income and ability. We introduce a non linear in means model of peer effect by shedding the light on the fact that school quality is not solely dependent on mean ability but also on the dispersion of abilities. We study the distribution of students across sectors while examining the conditions for the existence of a majority voting equilibrium in the context of non single peaked preferences. Finally, we examine the presence of a hierarchy of school qualities. In the paper we shed the light on equity problems related to the access to educational quality while analyzing the functioning of the educational system.
