A significant gap exists in the UK between the employment rate for Ethnic Minorities and that for Whites. From a policy perspective, it is important to know whether this gap is due to differences in the characteristics of White and Ethnic Minority groups (which reduce the employability of Ethnic...

Regression, matching, control function and instrumental variables methods for recovering the impact of education on individual earnings are reviewed for single treatment and sequential multiple treatments with and without heterogeneous returns. The sensitivity of the estimates once applied to a...

The low unemployment rates traditionally enjoyed by Sweden have often been attributed to the country's extensive system of active labour market programmes, which have thus frequently been regarded as a model for other countries to emulate. However, unemployment grew enormously in Sweden when the...

The paper evaluates the differential performance of the six main types of Swedish programmes that were available to adult unemployed workers en Titled to unemployment benefits in the 1990s: labour market training, workplace introduction, work experience placement, relief work, trainee...

We highlight the importance of randomisation bias, a situation where the process of participation in a social experiment has been affected by randomisation per se. We illustrate how this has happened in the case of the UK Employment Retention and Advancement (ERA) experiment, in which over one...

The 'Swedish model' of active labour market programmes is investigated in relation to some crucial institutional features with two aims: examining how successful it has been in the context of the high unemployment atypically experienced by Sweden in the 1990s and trying to derive some general...

One of the most powerful critiques of the use of randomised experiments in the social sciences is the possibility that individuals might react to the randomisation itself, thereby rendering the causal inference from the experiment irrelevant for policy purposes. In this paper we set out a...

Randomised controlled or clinical trials (RCTs) are generally viewed as the most reliable method to draw causal inference as to the effects of a treatment, as they should guarantee that the individuals being compared differ only in terms of their exposure to the treatment of interest. This 'gold...

We use UK administrative data to estimate the differential in labour market outcomes between Ethnic Minority benefit claimants and otherwise identical Whites. In many cases, Minorities and Whites are simply too different for satisfactory estimates to be calculated and results are sensitive to...

One of the most powerful critiques of the use of randomised experiments in the social sciences is the possibility that individuals might react to the randomisation itself, thereby rendering the causal inference from the experiment irrelevant for policy purposes. In this paper we set out a...
