In this paper we study the hedging of derivatives in illiquid markets. More specifically we consider a model where the implementation of a hedging strategy affects the price of the underlying security. Following earlier work we characterize perfect hedging strategies by a nonlinear version of...

This paper studies the evolution of wealth shares of portfolio rules in incomplete markets with short-lived assets. Prices are determined endogenously. The performance of a portfolio rule in the process of repeated reinvestment of wealth is determined by the wealth share eventually conquered in...

We demonstrate that in simple 2 X 2 games (cumulative) prospect theorypreferences can be evolutionarily stable, i.e. a population of players withprospect theory preferences can not be invaded by more rational players. Thisholds also if probability weighting is applied to the probabilities of...

We study probabilities which determine the payo of barrier options:the probability that an asset hits a barrier before maturity, theprobability that the asset is below the barrier at maturity, and theratio of both probabilities. The correct estimation of these probabilitieshas crucial eects on...

This paper presents a new method to detect informed trading activities in the options markets.An option trade is identified as informed when it is characterized by an unusual largeincrement in open interest and volume, induces large gains, and is not hedged in the stock market.For the period...

We study the influence of systematic probability misestimation on complexfinancial investment decisions on the context of structured financialproducts. Structured products have in recent years become more and morecomplex. We study the question whether this complexity might be a...

CEO compensation has increased substantially over the past 15 years, but so has forcedturnover. Motivated by this observation, we investigate whether part of the developmentof CEO pay can be explained by a premium which compensates CEOs for increased job risk.We ¯nd that for the CEOs of the...

Evolutionary nance studies the dynamic interaction of investment strategies in nancialmarkets. This market interaction generates a stochastic wealth dynamics on aheterogenous population of traders through the uctuation of asset prices and theirrandom payos. Asset prices are endogenously...

We study how the framework of classical game theory changes whenthe preferences of the players are described by Prospect Theory (PT)and Cumulative Prospect Theory (CPT) instead of Expected UtilityTheory. Specically, we study the inuence of framing eects and probabilityweighting on the existence...

In recent years, the number of automation projects has increased throughout the Finance Industry and particularly in securities trading and processing. The same observation can be made for corporate actions automation projects. Corporate actions messages are triggered when specific decisions are...
