Fact or Artefact : The Impact of Measurement Errors on the Farm Size - Productivity Relationship

This paper revisits the role of land measurement error in the inverse farm size and productivity relationship. By making use of data from a nationally representative household survey from Uganda, in which self-reported land size information is comp...

The findings indicate that using an improved measure of land size strengthens the evidence in support of the existence of the inverse relationship. 2012-03-19T18:06:41Z 2012-03-19T18:06:41Z 2011-12-01 http://www-wds.worldbank.org/external/default/main?menuPK=64187510&pagePK=64193027&piPK=64187937&theSitePK=523679&menuPK=64187510&searchMenuPK=64187283&siteName=WDS&entityID=000158349_20111212131701 http://hdl.handle.net/10986/3677 English Paper is funded by the Knowledge for Change Program (KCP),Policy Research working paper ; no.
