The UK Data Archive

The archive consists of data from four sources: the British Household Panel

Survey (BHPS), the Expenditure and Food Survey (formerly the Food and

Expenditure Survey, the FES), the Labour Force Survey (LFS) and the Survey

of Personal Incomes (SPI).

Access to the microdata in any of these datasets is restricted to registered

users. Researchers wishing to use the data must register a project with the

UK data archive at http://www.esds.ac.uk/aandp/access/access.asp and regis-

ter use of each dataset. When access has been granted users can then write to

me, Ben Etheridge at [email protected]; I can then send the cleaned datasets

used in this project. In practice, access should be a formality for academic

researchers.

The rest of the archive contains all the stata and matlab codes and docu-

mentation needed to process the data and reproduce results used in the paper.

Details of Each Dataset

BHPS

Data and documentation for the main BHPS dataset can be downloaded from

the UK data archive. Derived net household income data can be downloaded

here (code SN3909). The codes supplied can be applied to the raw, downloaded

data or researchers can e-mail me to obtain the compiled ready-to-use dataset,

panellong.dta. We advise the latter route.

Readme_BHPS.txt in the BHPS folder contains more information on run-

ning the codes once the raw/compiled data have been obtained.

FES

Data and documentation can be downloaded from e.g: here. The codes supplied

can be applied to the raw individual income data or researchers can e-mail

Ben Etheridge to obtain the compiled dataset, merged_inc_ind.dta. The raw

household expenditure data are extremely detailed and have been compiled and

cleaned over many years by researchers at the IFS. To protect this intellectual

capital we provide the household data at a more advanced stage of processing,

after they have been aggregated to total household non-durable expenditure and

after some data trimming. These data are contained in merged_hh_resid.dta.

For all data, we advise researchers to use the dataset created for this project.

Readme_FES.txt in the FES folder contains more information on running

the codes once the raw/compiled data have been obtained.

LFS

Information about the LFS can be found here. The LFS is not a core database

in the analysis and use of the data depends on much eort supplied by other

researchers at the IFS. Therefore, we provide fewer microdata from this survey.

and results from the LFS.
