ESL conducted as follows:

Household Survey:

  • Ensure data compatibility with previous income, expenditure and asset data in the socio-economic baseline for the REPDP 2013.

Data entry:

  • Input the survey data into the existing database

Data analysis:

  • Use household survey data to apply 3 income tests: 1) poverty elimination test, 2) economic parity test and 3) net income improvement test.
  • Identify households which do not pass the income tests.
  • Identify significant differences between baseline household incomes in REPDP 2013 and HIS at Effective Date +8 years, and identify the main reasons for the differences.


  • Report on the conduct of the survey and the results of the three household income tests.

Present the main findings to MoNRE and PNPC Lenders.
