simulated 6 different pattern of nonresponse bias and investigated the fade-away effect across the waves 2006 to 2009. We found … remarkable differences between these 25 coun- tries. Expressed by the relative bias, i.e. bias in 2009 divided by bias at start … in 2006, we found a reduction down to 26 percent of the initial bias for Bulgaria (foremost reduction) up to 61 percent …

High nonresponse rates have become a rule in survey sampling. In panel surveys there occur additional sample losses due … to panel attrition, which are thought to worsen the bias resulting from initial nonresponse. However, under certain … conditions an initial wave nonresponse bias may vanish in later panel waves. We study such a "Fade away" of an initial …
