ABSTRACT We find that option listings are associated with a decrease in the variance of the pricing error, a decrease in the adverse selection component of the spread, and an increase in the relative weight placed by the specialist on public information in revising prices for the underlying stocks. We also find that there is a decrease in the spread and increases in quoted depth, trading volume, trading frequency, and transaction size after option listings. Overall, our results suggest that option listings improve the market quality of the underlying stocks.

ABSTRACT This paper investigates the behavior of stock and option prices around block trades in stocks. The results indicate that for both up tick and downtick block trades the stock prices adjust within a fifteen minute period after the block trade. Moreover, for uptick blocks there is no evidence of any stock price reaction before the block trade. However, the adjustment of stock price for downtick blocks begins about fifteen minutes before the block trade. We also find that option price behavior differs considerably from stock price behavior. Specifically, our results suggest that options exhibit abnormal price behavior starting thirty minutes before the block and ending one hour after the block. The pattern is more pronounced for downtick blocks and for put options. We interpret this abnormal price behavior of options before the block trade as consistent with intermarket frontrunning.

We examine the impact of tax burden on cash distribution using a sample of Brazilian firms, which are allowed by law to distribute cash to shareholders in two forms: dividends and tax-advantaged interest on equity. The Brazilian institutional setting is superior to those used in prior studies that examine the choice between dividends and capital gains because, in some cases, dividends provide advantages that outweigh their negative tax consequences, leading firms to rationally choose payout policies that are not optimal when viewed only from the perspective of taxes. We find that taxes are a primary determinant of Brazilian firms’ payout policy decisions, as profitability and payout ratios (nonequity tax shields) are positively (negatively) related to the likelihood that a firm pays interest on equity. However, many firms continue to pay dividends despite the tax advantages of interest on equity payments. Abnormal returns around payout policy announcements suggest that these firms are, at least in part, catering to investor demand.
