Labour market signalling and job turnover revisited

Turnover by both low and high productivity workers occurs in all jobs. However, the reasons for turnover by workers of different abilities differ. When the probability that better workers transmit accurate signals to the labour market increases, we show that incumbent employers are more likely to adopt a separating wage offer strategy. This reduces the likelihood of turnover by more productive workers. We also show that turnover depends on a firm's willingness to match outside wage offers. Hence, the personnel and wage policies adopted by employers are important for understanding the turnover of workers of all productivity types. (C) 2003 Elsevier B.V. All rights reserved.
