This article examines the economics of paid sick leave from both theoretical and empirical perspectives. Research on paid sick leave has evolved dynamically over the last decade, primarily driven by the spread of US sick pay mandates, which have increased paid sick leave access from 63 percent to 77 percent in all US jobs. We begin by discussing the economic rationales for government regulation of paid sick leave, particularly the negative externalities associated with contagious diseases when individuals work while sick. After that, we discuss the key trade-offs in the general design of paid sick leave schemes, along with the trade-offs when setting specific policy parameters. Finally, we review economic modeling approaches to study optimal paid sick leave policies.
Pichler et al. (Fri,) studied this question.
