                     My Experiences

     –   Retail Sales Inquiry
     –   New Earnings Survey
     –   Investigation of bias from small business guarantees


• Produce and present reports
15




     New Earnings Survey Redesign

• Survey of earnings, hours, pension arrangements
• Currently a 1% sample of NI numbers in PAYE
  schemes
• From 2004 survey will
   – be stratified
   – include non-PAYE jobs (low pay)
   – have results weighted
   – include standard errors for all estimates
16




     NES Redesign - Sample Design

• Find which variables are best correlated with
  earnings
• Propose to stratify by occupation, sex, ageband,
  workplace region
• Relies on previous data for some information
• Post-stratify for calculation of results
17




        NES Redesign - Estimation

• Estimates will be weighted to account for non-
  response - design weights:
                       ai = Nh(s) / nh(s)

• Calibrate using LFS employee totals - calibration
  weights:
                   gi = Nh(ps) / Sj in h(ps) aj

• Weighted estimate of mean:
                mean(y) = Ss aj gj yj / Ss aj gj
18




     NES Redesign - Standard Errors

• Aim to publish standard errors with all estimates
• New methodology to estimate standard errors of
  weighted quantiles (based on estimation of the
  density)

• Software:
   – Generalised Estimation System (GES) and SAS
19




          Summarising Thoughts

• Interesting job, with many aspects, and good
  potential
• Project work - many parallels to academic research,
  though on a shorter timescale
• Experience from academic research very useful for
  MG work - e.g. report writing, working to deadlines
• Lots of training: SAS, sampling, Consultancy Skills,
  etc.
• Practical use of work done
