Short explanation of Schumpeter's concepts of dynamics, innovations and entrepreneurship. It is argued, that Schumpeters theory was highly relevant and should have been incorporated into the design of the reformed economic system, that attempted transition from Command to Socialist Market...

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...

What modern game theorists describe as 'fictitious play' is not the learning process George W. Brown defined in his 1951 paper. His original version differs in a subtle detail, namely the order of belief updating. In this note we revive Brown's original fictitious play process and demonstrate...

Fictitious play is the classical myopic learning process, and games with strategic complementarities are an important class of games including many economic applications. Knowledge about convergence properties of fictitious play in this class of games is scarce, however. Beyond dominance...

Fictitious play is the oldest and most studied learning process for games. Since the already classical result for zero-sum games, convergence of beliefs to the set of Nash equilibria has been established for some important classes of games, including weighted potential games, supermodular games...

It is known that every continuous time fictitious play process approaches equilibrium in every nondegenerate 2x2 and 2x3 game, and it has been conjectured that convergence to equilibrium holds generally for 2xn games. We give a simple geometric proof of this.
