Instrumental Variables vs. Grouping Approach for Reducing Bias Due to Measurement Error

Batistatou, Evridiki; McNamee, Roseanne - In: International Journal of Biostatistics 4 (2008) 1, pp. 1087-1087

Attenuation of the exposure-response relationship due to exposure measurement error is often encountered in epidemiology. Given that error cannot be totally eliminated, bias correction methods of analysis are needed. Many methods require more than one exposure measurement per person to be made,...

Combes, Pierre-Philippe; Duranton, Gilles; Gobillon, Laurent - C.E.P.R. Discussion Papers - 2008

Does productivity increase with density? We revisit the issue using French wage and TFP data. To deal with the ‘endogenous quantity of labour’ bias (i.e., urban agglomeration is consequence of high local productivity rather than a cause), we take an instrumental variable approach and...
