We develop a dynamic structural model to better understand how corporate payout policy is determined in conjunction with other corporate decisions. In a first-best model, a manager maximizes equity value by choosing the firm's optimal financing, investment, dividends, and cash holdings. By using simulated method of moments, we show that, on average, firms excessively smooth their payout while making corporate savings overly volatile and retaining excess cash. We then extend the model to capture the effect of a manager, who perceives a cost to cutting payouts. Estimating the model, we infer the magnitude of this cost. We find that a managerial preference for consistent payout explains the smooth payout and high volatility of cash holdings.
