To analyze the effect of health on work, many studies use a simple self-assessed health measure based upon a question such as “do you have an impairment or health problem limiting the kind or amount of work you can do?” A possible drawback of such a measure is the possibility that different groups of respondents may use different response scales. This is commonly referred to as “differential item functioning” (DIF). A specific form of DIF is justification bias: to justify the fact that they don’t work, non-working respondents may classify a given health problem as a more serious work limitation than working respondents. In this paper we use anchoring vignettes to identify justification bias and other forms of DIF across countries and socio-economic groups among older workers in the U.S. an...

Many western industrialized countries face strong budgetary pressures due to the aging of the baby boom generations and the general trends toward earlier ages of retirement. We use the American PSID and the European Community Household Panel (ECHP) to explain differences in prevalence and dynamics of self-reported work disability and labor force status. To that end we specify a two-equation dynamic panel data model describing the dynamics of labor force status and self-reported work disability. When we apply the U.S. parameters to the equations for the thirteen European countries we consider, the result is generally that work disability is lower and employment is higher. Furthermore, measures of employment protection across the different countries suggest that increased employment protecti...

This paper investigates the role of pain in determining self-reported work disability in the US, the UK and The Netherlands. Even if identical questions are asked, cross-country differences in reported work disability remain substantial. In the US and the Netherlands, respondent evaluations of work limitations of hypothetical persons described in pain vignettes are used to identify the extent to which differences in self-reports between countries or socio-economic groups are due to systematic variation in the response scales.
