Type: IFS Working Papers
This paper uses individual data on employment and wages to shed light on the UK’s productivity puzzle. It finds that workforce composition cannot explain the reduction in wages and hence productivity that we observe; instead, real wages have fallen significantly within jobs. Why? One possibility we investigate is higher labour supply in this recession than in the past. Another is lower trade union membership. Alternatively, it might be driven by a fall in productivity as a result of a lower capital-labour ratio. We cannot tell whether productivity is driving wages or vice versa, but understanding why wages have fallen within jobs is at the heart of the UK's productivity puzzle.

The UK's public finances in the long run: the IFS model
This working paper describes how the IFS’s model of the UK’s long-run public finances (and those of its constituent nations) is constructed.
Efficient responses to targeted cash transfers
In this paper, we estimate a collective model of household consumption and test the restrictions of collective rationality using z-conditional demands in the context of a large Conditional Cash Transfer programme in rural Mexico.
Policy discontinuity and duration outcomes
A comparison of hazard rates of duration outcomes before and after policy changes is hampered by non-identification if there is unobserved heteogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that overcomes this by exploiting variation in the moment at which different cohorts are exposed to the policy change, i.e. by considering spells crossing the policy change.
