It is now well known that the Sharpe ratio and other related reward-to-risk measures may be manipulated with option-like strategies. In this paper we derive the general conditions for achieving the maximum expected Sharpe ratio. We derive static rules for achieving the maximum Sharpe ratio with...

This article re-examines the evidence on the ability of dividend yields to predict long-horizon stock returns. We use two new series beginning in 1871, a monthly series for the United States, and an annual series for the United Kingdom. Conditional on survival over the entire 122 years, dividend...

This paper offers a novel explanation for why some firms prefer to pay dividends rather than repurchase shares. It is well-known that institutional investors are relatively less taxed than individual investors, and that this induces "dividend clientele" effects. We argue that these clientele...

Ireland went from being the poorest member of the European Economic Community in 1973 to enjoying the second highest per-capita income among European countries by 2007.  Healthy growth in the 1990s eventually gave way to a concentrated boom in property-related lending in the 2000s.  The growth...

All public companies in the European Union, including Ireland’s major banks, were required to adopt IAS 39 for their annual accounting periods beginning on or after January 1, 2005.  Under the “incurred loss” model of IAS 39, banks could set aside reserves for loan losses only when...
