Retirement is not only an individual decision, it is a decision taken within a family system. The extent to which estimates of retirement predictors are biased by the clustering of older workers (50 years of age or older) into dual-earner households remains unclear. Using longitudinal data on 11 European countries from the first (2004/ 2005) and second (2006/2007) waves of the Survey on Health, Ageing and Retirement in Europe (SHARE), this study investigated the retirement timing of older workers aged 50? living in dual-earner households in 11 European countries. We questioned how measures that are significantly related to retirement timing differ according to whether one takes into account the household context in the retirement analysis. The results showed that covariates that are dependent among partners (e.g., household size, educational level) changed the least between the Cox model and the shared frailty model. The effects of controlling for clustering between partners, although fairly modest, appeared to be important as they revealed a systematic pattern in the direction of bias in estimates that assume an independent sample.
