The impact of insider trading laws on dividend payout policy

We posit that firms use dividend payout policy to reduce information asymmetry and agency costs caused by country-level institutional weaknesses. Firms operating in countries with weak insider trading laws attempt to mitigate this institutional weakness by committing themselves to paying out large and stable cash dividends. We test this central hypothesis (among others) using an international sample of firms across 24 countries, as well as by conducting a case study during an enforcement action. The results show that weak insider trading laws lead to a higher propensity of paying dividends, larger dividend amounts and greater dividend smoothing. We also show that the market's valuation of dividend payouts is significantly higher when insider trading protection is weak. It is important to note that these insider trading results are not due to cross-country variations in investor or creditor protection, nor are they contingent on the enforcement of insider trading laws. Overall, our evidence supports the view that dividend payouts serve as a substitute bonding mechanism when country-level legal protections fail. •Firm-level payout policy reduces problems caused by country-level institutions.•Weak insider trading laws are overcome by higher dividend frequencies and amounts.•Dividend market valuations are higher when country-level protection is weak.•Dividends serve as substitute bonding mechanism for institutional weaknesses.
