  We develop a unified framework for the measurement and valuation of health
and productivity. Within this framework, we characterize evaluation functions
allowing for compromises between the classical quality-adjusted life years
(QALYs) and its polar productivity-adjusted life years (PALYs). Our framework
and characterization results provide a new normative basis for the economic
evaluation of health care interventions, as well as occupational health and
safety policies, aimed to impact both health and productivity of individuals.
