The term “big data” has gotten increasing popular attention, and there is growing focus on how such data can be used to measure and improve health and healthcare. Analytic techniques for extracting information from these data have grown vastly more powerful, and they are now broadly available. But for these approaches to be most useful, large amounts of data must be available, and barriers to use should be low. We discuss how “smart cities” are beginning to invest in this area to improve the health of their populations; provide examples around model approaches for making large quantities of data available to researchers and clinicians among other stakeholders; discuss the current state of big data approaches to improve clinical care including specific examples, and then discuss some of the policy issues around and examples of successful regulatory approaches, including deidentification and privacy protection.

This paper analyzes the dynamics in employment and informal care outcomes of women in England. To this end, we develop a dynamic model to describe pathways leading to a negative correlation between informal care and employment in a cross-section. The model allows for different types of caregiving, correlated permanent unobserved heterogeneity and initial sorting. The model is estimated on data from 6 waves of the BHPS 2000–2005. Our findings suggest modest feedback effects. We find a negative effect of co-residential caregiving on future employment and a negative effect of employment on future co-residential and extra-residential caregiving. We also find evidence of positive state-dependence in caregiving although most of the persistence in such activities is related to unobserved heterogeneity rather than state-dependence.

A substantial proportion of working age individuals in Britain are looking after sick, disabled or elderly people, often combining their work and caring responsibilities. Previous research has shown that informal care is linked with substantial opportunity costs for the individual due to forgone wages as a result of non-labour market participation. In this paper we show that informal carers exhibit further disadvantages even when participating. Using the British Household Panel Study (BHPS) we decompose wage differentials and show that carers can expect lower returns for a given set of characteristics, with this wage penalty varying along the pay distribution and by gender. Furthermore, opportunity costs from forgone wages and wage penalties are estimated and found to be substantial.

Around 14% of the UK labour force has informal care responsibilities and almost everyone in society will be an informal carer in their lifetime. A well-known fact in the small economic literature on informal care is the apparent negative relation between care responsibilities and labour market participation. Yet, caring and labour market participation may be endogenous. Using an instrumental variable approach and panel data techniques and employing data from the British Household Panel Study from 1991 to 2002, this paper shows that not accommodating for endogeneity in the labour market participation equation may significantly overestimate the impact care exhibits on the employment decision of informal carers. Moreover, it is shown that a negative impact on employment only applies to some care-types. Policy implications are derived.

There are more than 5 million carers in the UK. These provide a vital low cost resource to support frail older people. Without their continued participation in caring activities, governments would face a steep increase in formal care costs. Therefore the issue of substitution between formal and informal care is a vital policy issue. This paper explores a recent “natural experiment” in care provision. In 2002, the Scottish Parliament agreed to provide personal care free of charge to all those in need of such care. This policy was not followed elsewhere in the UK. Social conditions and data resources are largely uniform throughout the UK; this permits a reasonably rigorous evaluation of the initial impact of the policy of free personal care on informal caring behaviour. Using a difference-in-difference methodology with the British Household Panel Survey, the authors show that informal caring in Scotland did not decrease relative to the rest of the UK after the substantial expansion in formal provision in Scotland. While the finding is in line with other international evidence, the paper argues that it may partly be explained by changes in the type of care that informal carers provide following the policy change.

This paper proceeds from two key assumptions. The first is that European countries are likely to face increased immigration of individuals. The second is that the emigration of jobs from Europe to other regions of the world through offshoring is also likely to increase. It has been widely argued that both factors are contributing to growing insecurity among European workers. This paper has two goals: first, to put the wider discussion of job displacement and wage changes resulting from immigration and offshoring on a firmer empirical foundation; and second, to explore changes in the European social model that will allow the European economies to adjust to the challenges and respond to the opportunities resulting from increased global competition from emerging market economies. Both immigration and offshoring confront European policy makers with trade-offs between efficiency and equity. These tradeoffs can be eased by active labour market and education policies to enhance the flexibility and skills of European workers so that they enjoy the productivity advantages necessary to support high wages and compete in the global economy. Such policies must combine an appropriate balance of incentives, obligations and benefits that focus on the overall employability of workers rather than on the number of jobs in a particular company or sector. A key challenge in designing such policies is how to combine generous income support for jobseekers while at the same time strengthening their incentives to find and accept available jobs.

Previous immigration facilitates future immigration, a phenomenon called network migration. While well recognized, previous research has mainly focused on the implications of immigrant networks on future migrants. In contrast, this paper derives a simple model from the perspective of the incumbent immigrant population by introducing sub-networks and argues that the incumbent migrants fail to achieve a Pareto optimal network size due to differences in inter- and intra-migrant group externalities and subsequently coordination failures. In short, it stresses the active role incumbents take in the provision of network effects and provides theoretical evidence that self-perpetuating and sustained immigration is not at odds with rational acting individuals. It also shows that optimally chosen migration quotas may appeal to incumbent migration cohorts and provides an alternative explanation for inter- and intra-migrant group tensions.

The Scottish extension-sample of the British Household Panel Study (BHPS) is used to shed light on differences in job mobility patterns in England and Scotland for both men and women. Based on probit estimates of the overall mobility rate, a decomposition is applied to distinguish between explained and unexplained differences. Furthermore, exploiting data on the number of job changes, a zero inflated Poisson model is estimated to provide information on possible differences in the expected number of job changes. Overall, there is evidence that suggests significant differences in mobility patterns south and north of the Borders; however, these are confined to men. Yet, whether this suffices to justify a heterogeneous labour market policy for the two countries remains to be seen.

With reference to the EU enlargement, a framework is derived which allows the study of the effect of unemployment benefits on the migration decision. While benefits simply increase the expected gain for risk neutral individuals, they work as an insurance device for risk averse migrants; the results for the two groups might differ. Thus, the migration decision is reformulated as monetary lottery and a utility function exhibiting constant relative risk aversion is applied. The model suggests increased migration incentives independent of taste and a positive selection of risk neutral individuals. Furthermore, risk averse migrants are likely to be found in countries with more evenly distributed incomes, other things equal. While the calibration of the model shows a significant change in migration incentives, empirical results on aggregate data for South-North migration within the EU are rather ambiguous.
