Many household panel surveys have experienced decreasing response rates and increasing risk of nonresponse bias in … recent decades, but trends in response rates and nonresponse bias in business or establishment panel surveys are largely … understudied. This article examines both panel response rates and nonresponse bias in one of the largest and longest …

We consider two semiparametric models for the weight function in a bias sample model. The object of our interest …

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 …

We propose a new view of initial nonresponse bias in longitudinal surveys. Under certain conditions, an initial bias …
