The data: a brief description

This paper provides a brief description of all the data we provided for use in our experiment in applied econometrics: aggregate time-series data for the USA and The Netherlands; cross-section sample-survey budget data for the USA; and cross-section household-level budget data for The Netherlands. We include brief descriptions of the data sets, definitions of the variables involved and documentation of original sources. We indicate where full information about the data, and the data themselves, can be found.
