Unique and proprietary data of the illiquid, one-year non cancelable for three month Bermudan swaps (1Y NC 3M swaps) and one-year non callable for three months Bermudan CDs (1Y NC 3M CDs), provides evidence of market efficiency. The 1Y NC 3M swap and 1Y NC 3M CD markets efficiently reflected unexpected economic information. The 1Y NC 3M swaption premiums also followed the European one-year into three-month (1Y into 3M) swaption volatilities. Swaption premiums were computed by pricing non-optional instruments using the quoted 1Y NC 3M swap rates and the par value swap rates and taking the difference between them. Swaption premiums ranged from a slight negative premium to a 0.21 percent premium. The average swaption premium during the study period was 0.02 percent to 0.04 percent. The initial swaption premiums were over 0.20 percent while the final swaption premiums were 0.02 percent to 0.04 percent. Premiums peaked and waned throughout the study period depending on market uncertainty as reflected in major national economic announcements, Federal Reserve testimonies and foreign currency devaluations. Negative swaption premiums were not necessarily irrational or quoting errors. Frequently, traders obligated to provide market quotes to customers do not have an interest and relay that lack of …

This study examines the reactions of market makers and investors to large dividend increases to identify the motives for dividend increases. Uniquely, this study simultaneously tests the signaling and agency abatement motivations as explanations of the impact of dividend increases on stock prices and bid-ask spreads. The agency abatement hypothesis argues that increased dividends constrict management's future behavior, abating the agency problem with shareholders. The signaling hypothesis asserts that dividend increases signal that managers expect higher or more stable cash flows in the future. Mean stock price responses to dividend increase announcements during 1995 are examined over both short ( _1, 0) and long ( _1, 504) windows. Changes in bid-ask spreads are examined over a short ( _1, 0) window and an intermediate (81 day) period. This study partitions dividend increases into a sample motivated by agency abatement and a sample motivated by cash flow signaling. Further, this study examines the agency abatement and cash flow signaling explanations of relative bid-ask spread responses to announcements of dividend increases. Estimated generalized least squares models of market reactions to sampled events support the agency abatement hypothesis over the cash flow signaling hypothesis as a motive for large dividend increases as measured …
