We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we compare the effect of adding a contract market with the introduction of an additional competitor, changing ...

In this paper we present a model for the dynamic evolution of the term structure of default-free and defaultable interest rates. The model is set in the Libor market model framework but in contrast to the classical diffusion-driven setup, its dynamics are driven by a time-inhomogeneous Lévy process which allows us to better capture the real-world dynamics of credit spreads. We present necessary...

The value of market information depends not only on its accuracy, but also on the e-retailer’s market power and the product’s Web ...

We study the problem of computing equilibrium prices in a Fisher market with linear utilities and linear single-constraint production units. This setting naturally appears in ad pricing where the sum of the lengths of the displayed ads is constrained not to exceed the available ad space. There are three approaches to solve market equilibrium problems: convex programming, auction-based algorithm...
