Existence of financial equilibria in continuous time with potentially complete markets
Riedel, Frank; Herzberg, Frederik - 2010
We prove that in smooth Markovian continuous-time economies with potentially complete asset markets, Radner equilibria with endogenously complete markets exist.

Endogenous credit derivatives and bank behavior
Pausch, Thilo - 2007
Instruments for credit risk transfer arise endogenously from and interact with optimizing behavior of their users. This is particularly true with credit derivatives which are usually OTC contracts between banks as buyers and sellers of credit risk. Recent literature, however, does not account...

On free lunches in random walk markets with short-sale constraints and small transaction costs, and weak convergence to Gaussian continuous-time processes
Framstad, Nils Chr. - 2011
This paper considers a sequence of discrete-time random walk markets with a single risky asset, and gives conditions for the existence of arbitrage opportunities or free lunches with vanishing risk, of the form of waiting to buy and selling the next period, with no shorting, and furthermore for...

Testing the Modigliani-Miller theorem directly in the lab: a general equilibrium approach
Qiu, Jianying; Mahagaonkar, Prashanth - 2009
In this paper, we directly test the Modigliani-Miller theorem in the lab. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structures, we are able to address this issue without making any assumptions about individuals' risk attitudes and...

Testing the Modigliani-Miller theorem directly in the lab: a general equilibrium approach
Mahagaonkar, Prashanth; Qiu, Jianying - 2008
In this paper, we experimentally test the Modigliani-Miller theorem. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structure, we are able to address a question fundamental to the valuation of firms: does capital structure affect the...

Finance without probabilistic prior assumptions
Riedel, Frank - 2011
We develop the fundamental theorem of asset pricing in a probability-free infinite-dimensional setup. We replace the usual assumption of a prior probability by a certain continuity property in the state variable. Probabilities enter then endogenously as full support martingale measures (instead...

Introducing a spread into the Kyle model
Salomonsson, Marcus - 2009
The Kyle (1985) model is extended to take into account market maker competition and the spread. It is shown that with a spread the Kyle model has a Nash equilibrium also with two market makers, not only with three or more, as shown in earlier research. The spread is endogenized, and two testable...

Fund flows inducing mispricing of risk in competitive financial markets
Stahmer, Axel - 2015
This paper studies the effect of new fund flows on investment behavior and the resulting equilibrium price of risk. The Small Fund Industry model shows equilibria with overinvestment in unprofitable and underinvestment in profitable investment opportunities. The Large Fund Industry model derives...
