Immigration is often seen as an instrument of adaptation for ageing countries. In this paper, we evaluate, using a dynamic general equilibrium model, the contribution of migration policy in reducing the tax burden associated with the ageing population in France. Four alternative scenarios, compared with a baseline scenario based on official projections, are simulated with the aim of quantifying the effects of immigration on French social protection finances. We show that the age and, to a lesser extent, the skill structure of immigrants are the key features that mainly determine the effects on social protection finances. Overall, these effects are all the more positive in the short to medium term if the migration policy is selective (in favour of more skilled workers). In the long term, the beneficial effects of a selective policy may disappear. But whatever the degree of selectivity of the migration policy, the financial gains from higher consequent migration flows are relatively moderate compared with the demographic changes implied by ageing.

We assigned two cohorts of kindergarten students, totaling more than 24,000 children, to teachers within schools with a rule that is as good as random. We collected data on children at the beginning of the school year and applied 12 tests of math, language, and executive function (EF) at the end of the year.

We estimate a dynamic model of employment, human capital accumulation - including education, and savings for women in the UK, exploiting tax and benefit reforms, and use it to analyze the effects of welfare policy.

This report examines the impact of the changes to the tax and benefit system to be introduced by the UK Government between April 2015 and April 2019 in Wales and compare this to average impacts across the whole UK.

The objective of this paper is to understand and test empirically the relationship between group size and informal risk sharing. Models of informal risk sharing with limited commitment and grim-trigger punishments upon deviation imply that larger groups provide better informal insurance.

This paper extends analyses of association between maternal mental health and infant growth in low- and middle-income countries (LMICs) to children through age eight years, and broaden analyses to cognitive and psychosocial outcomes.

This paper analyses the impact of centrally regulated pay on the quality of applicants to be police officers in England and Wales using a unique dataset of individual test scores from the national assessment that is required of all applicants.
