Using state-level data on productive and unproductive entrepreneurship, shadow economy size, and public official corruption, this paper examines whether formal sector productive (unproductive) entrepreneurial activity is associated with lower (higher) levels of informal economic activity....

We examine theoretically and empirically social interactions in labor markets and how policy prescriptions can change dramatically when there are social interactions present.
