This paper provides a general overview of the literature on the core of an exchange economy with asymmetric information. Incentive compatibility is emphasized in studying core concepts at the ex ante and interim stage. The analysis includes issues of non-emptiness of the core as well as core...

This article shows that, as long as agents are required to maintain positivewealth, the presence of portfolio constraints may give rise to asset pricingbubbles in equilibrium even if there are unconstrained agents in the economywho can benefit from the induced arbitrage opportunity. Furthermore,...

We develop a new completely affine model of the term structure of interest rates, in which the statevariables evolve as a matrix-valued process of stochastically correlated factors. This setting grants a newelement of flexibility in the simultaneous modeling of stochastic volatilities and...

Markowitz and Sharpe won the Nobel Prize in Economics more than a decade ago for the development of Mean-Variance analysis and the Capital Asset Pricing Model (CAPM). In the year 2002, Kahneman won the Nobel Prize in Economics for the development of Prospect Theory. Can these two apparently...

As early as 1934 Graham and Dodd conjectured that excess returns from value investment originate from a tendency of markets to converge towards fundamental values. This paper confirms their insights theoretically within the evolutionary finance model of Evstigneev, Hens, and Schenk-Hopp (2006)...

Under the assumption of normally distributed returns, we analyzewhether the Cumulative Prospect Theory of Tversky and Kahneman (1992)is consistent with the Capital Asset Pricing Model. We find that in everyfinancial market equilibrium the Security Market Line Theorem holds.However, under the...

In this paper we review recent developments in axiomatic studies of Marxian exploitation theory. First, given the acute controversy over the formal definition of exploitation during the 1970-1990s, we review the study of the axiomatic framework, which identifies some fundamental properties -...

This paper studies the asset pricing implications of a general equi-librium model in which real investment is reversible at a cost. Firmsface higher costs in contracting than in expanding their capital stockand decide to invest when their productive capital is scarce relativeto the overall...

We introduce a new class of flexible and tractable matrix a±ne jump-diffusions (AJD) to modelmultivariate sources of financial risk. We first provide a complete transform analysis of this model class,which opens a range of new potential applications to, e.g., multivariate option pricing with...

In an exchange economyw ith a finite number of indivisible goods, we analyze a dynamic trading process of coalitional recontracting where agents may make mistakes with small probability. We show first that the recurrent classes of the unperturbed (mistakefree) process consist of (i) all core...
