This paper rectifies a design problem in the Santa Fe Artificial Stock Market Model. Due to a faulty mutation operator, the resulting bit distribution in the classifier system was systematically upwardly biased, thus suggesting increased levels of technical trading for smaller GA-invocation...

The model of Technical Analysis goes against the fulfillment of the weak form of the Hypothesis of Efficient Market raised by Fama (1970). Nevertheless, recently some studies provide evidence with probable prediction of the expected returns based on the past returns. In particular, the...

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 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...

Inertia in academia sometimes obstructs the development of important insights. That is one reason for the specially long gap separating Coase's seminal paper [1937] that laid the foundations of current Transaction Cost Economics (TCE) and the efforts of scholars to develop his ideas. But as TCE...

Transaction Costs Theory has been considered the 'new orthodoxy' in the theory of the firm, being this the very same reason for wide criticism by different schools of economic thought. However, there seems to be signs of complementarity between TCT and evolutionary approaches to the firm. Some...

In this paper we examine the problem of finding investors' reservation option prices and corresponding early exercise policies of American- style options in the market with proportional transaction costs using the utility based approach proposed by Davis and Zariphopoulou (1995). We present a...

In this paper we extend the utility based option pricing and hedging approach, pioneered by Hodges and Neuberger (1989) and further developed by Davis, Panas and Zariphopoulou (1993), for the market where each transaction has a fixed cost component. We present a model, where investors have a...

The theory of asset pricing, which takes its roots in the Arrow-Debreu model (Theory of value [1959, chap. 7]), the Black and Sholes formula (1973) and Cox and Ross (1976 a and b), has been formalized in a general framework by Harrison and Kreps (1979), Harrison and Pliska (1979) and Kreps...

This paper examines why some transitions are more successful than others by focusing attention on the role of productive, protective and predatory behaviors from the perspective of the new institutional economics. Many transition economies are characterized by a fundamental inconsistency between...
