A Note on Portfolio Selections under Various Risk Measures
This work gives a brief overview of the portfolio selection problem following the mean-risk approach first proposed by Markowitz (1952). We consider various risk measures, i.e. variance, value-at-risk and expected-shortfall and we study the efficient frontiers obtained by solving the portfolio selection problem under these measures. We show that under the assumption that returns are...

An Application of Evolutionary Finance to Firms Listed in the Swiss Market Index
This paper presents an application of evolutionary portfolio theory to stocks listed in the Swiss Market Index (SMI). We study numerically the long-run outcome of the competition of rebalancing rules for market shares in a stock market with actual dividends taken from firms listed in the SMI. Returns are endogenous because prices are determined by supply and demand stemming from the...

Acquisitions versus Entry: The Evolution of Concentration
We consider market dynamics in a reduced form model. In the simplest version, there are two investors and several small noninvesting firms. In each period, one investor can acquire a small firm, the other investor decides about market entry. After that all firms play an oligopoly game. We derive conditions under which increasing market concentration arises with myopic firms, we show...

Resuscitating the Cobweb Cycle
"This note shows that permanent fluctuations in the Cobweb model — though inconsistent with a rational expectations equilibrium — can be justified as being rational when reinterpreting the model in the theory of rational beliefs."

Subjektive Daten in der empirischen Wirtschaftsforschung: Probleme und Perspektiven
Preise, Einkommen, und Nachfrage – die zentralen zu erklaerenden Variablen in den Wirtschaftswissenschaften sind objektiv messbar. Daneben gibt es jedoch zwei nicht minder zentrale Groessen, Erwartungen und Praeferenzen, die sich einer direkten objektiven Messung entziehen. Es sind subjektive Variablen, also solche, die von persoenlichen Meinungen und Erfahrungen bestimmt sind....

‘Thou art a scholar, speak to it' - On Spaces of Speech : A Script
This article argues, based on the work of Bakhtin and de Certeau, that there is no aesthetics without politics and that all academic discourse and practices are enacted through aesthetic forms with inherently political and ethical effects. The article is written in a script-form with indications on how to perform it, acting out or ‘performing' in a direct way rather than adding...

"Publishing as Prostitution? Choosing Between One‘s Own Ideas and Academic Failure"
Survival in academia depends on publications in refereed journals. Authors only get their papers accepted if they intellectually prostitute themselves by slavishly following the demands made by anonymous referees without property rights on the journals they advise. Intellectual prostitution is neither beneficial to suppliers nor consumers. But it is avoidable. The editor (with...
