Mixed mode designs are increasingly important in surveys and large longitudinal studies are progressively moving to or considering such a design. In this context our knowledge regarding the impact of mixing modes on data quality indicators in longitu- dinal studies is sparse. This study tries to...

The quasi-simplex model makes use of at least three repeated measures of the same variable to estimate its reliability. The model has rather strict assumptions about how various parameters in the model are related to each other. Previous studies have outlined how several of the assumptions of...

Using multiple modes to collect data is becoming a standard practice in survey agencies. While this should save costs and decrease non-response error it may have detrimental effects on measurement quality. This can happen because different modes have distinct measurement biases which, when...

This paper presents two optimising models of individual or parental educational choice, and discusses issues of identification and estimates earnings equations in the context of these models. The estimates indicate that education is endogenous for young men's earnings, but not for young women....

This paper looks at the effect of quitting on the number of workers trained under conditions of uncertainty about future productivity when workers have both firm-specific and industry- specific skills. A new effect is found which works in the opposite direction of the undertraining result of...

The issue of third parties' presence in face-to-face interview situations is a familiar, yet often unexamined phenomenon. Whilst there is often an implicit or explicit instruction to interviewers to interview respondents alone, there is little conclusive evidence to suggest that the presence of...

The paper models the transitions rates between the three main housing tenures in Britain. "Surprises" like partnership break-up, acquisition of a partner and spells of unemployment are found to have large impacts on tenure changes. Through their effects on these transition rates, variation in...

Household labour supply models are typically estimated on data sets containing information on family consumption and male and female hours of market work. The estimating equations are consistent with a theoretical model which assumes the maximisation of a household utility function defined on...
