The top executives' demands for financial instruments that enable them to hedge the risk exposure in their compensation has increased drastically in the last decade. We analyse the implications of a manager's hedging ability for effort incentives. We show that if the manager's hedging opportunity is limited to a known fixed number of trading rounds with risk-neutral third parties, then the equilibrium effort is not affected at all. If the manager has the opportunity to hedge without committing to a last trading round, however, she hedges completely and no effort incentives can be sustained. Therefore, limiting the manager's opportunity to hedge to a fixed known number of trading rounds is crucial for sustaining incentives. JEL classification: G30, G32.
