[By buying convertibles and shorting the underlying stock, hedge funds distribute equity exposure to well-diversified shareholders. We find that firms with characteristics that make seasoned equity offerings expensive are more likely to issue convertibles to hedge funds. We conclude that hedge funds provide opportunities for firms to issue convertible securities at a lower cost than seasoned equity by serving as relatively low-cost distributors of equity exposure. A higher fraction of a convertible is privately placed with hedge funds when institutional ownership, stock liquidity, issue size, concurrent stock repurchases, and limitations on callability suggest that shorting costs will be lower.]

The effectiveness of any sanction depends on the costs of avoiding its restrictions. We examine whether bearish option strategies were substitutes for short sales during the September 2008 short-sale ban. We find a significant diminution in option volumes and a significant increase in option bid-ask spreads for banned stock relative to unbanned stock during the ban period. Apparent violations of the put-call parity bound became significantly more frequent for banned stocks during the ban period. We conclude that the ban acted as an effective restriction on trading in options.
