Evans D., Kula E. and Sezer H. (2005) Regional welfare weights for the UK: England, Scotland, Wales and Northern Ireland, Regional Studies 39 , 923–937. In relation to public spending and regional policy, the importance of distributional issues is stressed, and regional welfare weights are derived from an appropriate underlying social welfare function. Estimates of these weights are then provided for the four countries comprising the UK. Welfare weights now have a very high policy profile following the special emphasis placed by the UK Treasury, in its recently revised guidance on appraisal and evaluation in government, on the assessment of the distributional impacts of social projects and policies. From an empirical perspective, the critical component of each welfare weight measure is the elasticity of marginal utility of income ( e ). Alternative estimation approaches based on demand analysis and income tax data are used to determine e , and a preferred measure of 1.60 emerges. The resulting regional welfare weights are then compared with recent patterns of per‐capita regional public expenditure in the UK. The paper concludes by emphasizing the scope for further empirical work on welfare weights and regional policy in relation to both the UK and the European Union.
