First, the presence of an employer who invests in the health of the employee implies that the levels of health will be higher for all family members when the husband supplies some of his time to the labour market provided that employer’s investments are not completely crowded out by a reduction in the family’s investments. However, to decrease health levels when resources increase cannot be consistent with maximisation of the family’s lifecycle utility, since marginal utilities of health are always positive and since the utility of each family member’s health capital is increasing both in the level of health of the other family members and in consumption.
