Agency Costs in Small Firms

Milo Bianchi, and Henri Luomaranta

Abstract

We explore how CEO ownership a¤ects productivity in small and large firms. We use administrative panel data on the universe of limited lia- bility firms in Finland and exploit plausibly exogenous variations to CEO ownership induced by shocks to the CEO spouse's health. We document a substantial increase in productivity when the CEO obtains majority owner- ship or when the majority owner becomes the CEO. While typical samples focus on large public rms, we show that our e¤ects are stronger in medium- sized private firms. Consistently with the quiet life hypothesis, we show that increased ownership boosts CEO's effort at work.
