This study tests weak and semi-strong form efficiency of the foreign exchange market in Sri Lanka using six bilateral foreign exchange rates during the recent float. Weak-form efficiency is examined using unit root tests while semi-strong form efficiency is tested using co- integration and...

This paper examines the validity of the efficient market hypothesis (EMH) for the foreign exchange market of Papua New Guinea (PNG) using data on spot exchange rates for four major foreign currencies during the recent float. The unit root test results indicate that all the four exchange rates...

This paper addresses a very profound question concerning financial accounting. Is financial accounting measurement. as represented by diverse valuation rules. hodgepodge or is it logically developed? Salvary [1985. p.28. Chap. IV] advances and provides a theoretical development of the concept of...

If each member of a group assigns a certain probability to a hypothesis, what probability should the collective as a whole assign? More generally, how should individual probability functions be merged into a single collective one? I investigate this question in case that the individual...

This paper develops a utility model for evaluating lotteries. In estimating utility, risk averse people use an asymmetric loss function. Expected utility is seen as a special case that is a good approximation in some cases. The model resolves several paradoxes and makes easily falsifiable...

A quadratic discrete time probabilistic model, for optimal portfolio selection in (re-)insurance is studied. For positive values of underwriting levels, the expected value of the accumulated result is optimized, under constraints on its variance and on annual ROE's. Existence of a unique...
