Secondary Analyses of NDLP and LPWFI data
Funded by: Department for Work and Pensions
April 2004 to July 2005
Background, summary and aims
Strand 1 Understanding the impact of NDLP on LPWFI clients: To address the aims of strand 1 we propose a programme of descriptive analysis and impact estimation. The general format for the descriptive analyses is a before-after design, comparing aspects of NDLP participants and their outcomes prior to the introduction of LPWFI with those after the introduction of LPWFI. We propose that the impact of NDLP on LPWFI clients be estimated using matched comparison group techniques with propensity score matching, including multiple treatment matching methods. In order to make full use of the data available, systematic comparisons would be made using the survey data as well as the various administrative data sources, including IR data, for employment and benefit outcomes.
Strand 2 The relationship between IWBC received, and work: The LPWFI and NDLP survey interview data linked with administrative data will be used to examine the contribution of the IWBC. The comparative analysis will separately consider the role of the IWBC in NDLP, and the role of the IWBC in LPWFI using a combination of descriptive and regression analyses.
Strand 3 Extension of tracking of NDLP outcomes: The project will build on the early evaluation completed by NCSR and the subsequent longer run econometric analysis by Dolton et al (2003). The long run impact of NDLP on its participants will be assessed by examining the same individuals used for the strand 4 analysis to see if the programme continues to have an effect on their labour market outcomes up to 5 years after participation.
