The mission of the Economic and Social Research Institute is to advance evidencebased policymaking that supports economic sustainability and social progress in Ireland. ESRI researchers apply the highest standards of academic excellence to challenges facing policymakers, focusing on 12 areas of critical importance to 21st Century Ireland.The Institute was founded in 1960 by a group of senior civil servants led by Dr T. K. Whitaker, who identified the need for independent and in-depth research analysis to provide a robust evidence base for policymaking in Ireland.Since then, the Institute has remained committed to independent research and its work is free of any expressed ideology or political position. The Institute publishes all research reaching the appropriate academic standard, irrespective of its findings or who funds the research.The quality of its research output is guaranteed by a rigorous peer review process. ESRI researchers are experts in their fields and are committed to producing work that meets the highest academic standards and practices.The work of the Institute is disseminated widely in books, journal articles and reports. ESRI publications are available to download, free of charge, from its website. Additionally, ESRI staff communicate research findings at regular conferences and seminars.The ESRI is a company limited by guarantee, answerable to its members and governed by a Council, comprising 14 members who represent a cross-section of ESRI members from academia, civil services, state agencies, businesses and civil society. The Institute receives an annual grant-in-aid from the Department of Public Expenditure and Reform to support the scientific and public interest elements of the Institute's activities; the grant accounted for an average of 30 per cent of the Institute's income over the lifetime of the last Research Strategy. The remaining funding comes from research programmes supported by government departments and agencies, public bodies and competitive research programmes.

We exploit variation in National Insurance contributions (NICs) -the UK's system of social security contributions -and a large panel dataset to examine the effects of 35 years of employee and employer NICs reforms on labour cost (gross earnings plus employer NICs), hours of work and labour cost per hour, both immediately (0-6 months) after reforms are implemented and in the slightly longer term (12-18 months). We consider assumptions under which the estimated coefficients on net-of-marginal and net-of-average tax rates in a panel regression can be interpreted as behavioural elasticities or as reflecting incidence. We find a compensated elasticity of taxable earnings with respect to the marginal rate of employee NICs of about 0.2-0.3, operating largely through hours of work, while that with respect to the marginal rate of employer NICs is not statistically significantly different from zero. We also find that labour cost falls by a much larger amount when the average rate of employer NICs is reduced than when the average rate of employee NICs is reduced, which is consistent with the economic incidence of NICs being strongly affected by its formal legal incidence. Estimates from the hours and hourly labour cost regressions provide further support to this interpretation of the findings, and also suggest the presence of substantial income effects -though also, after 1999, a puzzling effect of average employer NICs rates on hours of work. Each of these results remains true after 12-18 months (if anything, coefficients on lagged changes in NICs rates strengthen these findings), implying that any shifting of employer NICs changes to the individual employees concerned (and vice versa for employee NICs) does not begin over this time horizon. These results are similar to those found by Lehmann et al. (2013) for France but represent an extension of that work by considering hours as well as labour cost responses and second-year as well as immediate effects.

Most analyses of inequality and tax and benefit reforms are based on measures of individuals' circumstances at a point in time. But strong age-profiles in earnings, among other characteristics that the tax and benefit system conditions upon, combined with individuals' ability to transfer resources across time suggests that measuring circumstances over longer horizons may lead to a very different picture. In this article, we consider how our impression of inequality and the tax and benefit system changes when the horizon under consideration is extended. We show that inequality is lower, redistribution less extensive, and benefit receipt far more widespread from a longer-run perspective. The choice of accounting period can also lead to a very different assessment of the distributional impact of policy reforms. Our results show the importance of policymakers explicitly considering what it is they are trying to achieve through redistribution: the alleviation of short-run hardship or the reduction of lifetime inequality. While there may be good reasons to pursue both objectives, the group of people affected and the appropriate policy response will differ depending on which is prioritized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
