The Internet reduces the cost of exchanging information. Electronic markets exploit this opportunity to enable investors to place quotes at very little cost and compete with incumbent trading systems. Does this quasi–free entry situation lead to competitive liquidity supply? We analyze trades...

We analyze theoretically and empirically the implications of heterogeneous information for equilibrium asset pricing and portfolio choice. Our theoretical framework, directly inspired by Admati (1985), implies that with partial information aggregation, portfolio separation fails, buy-and-hold...

As a centralized, computerized, limit order market, the Paris Bourse is particularly appropriate for studying the interaction between the order book and order flow. Descriptive methods capture the richness of the data and distinctive aspects of the market structure. Order flow is concentrated...

Because the Paris Bourse is a centralized, computerized, limit order market, the dataset it generates is particularly appropriate for studying the interaction between the order book and order flow dynamics. We use descriptive methods to capture the richness of the data and the distinctive...

SD-Solver is a general purpose simulation environment grounded on the Constraint Logic Programming technology. Its main aim is to facilitate the development of Decision Support Systems based on dynamic models. Using SD-Solver, forward and backward simulations can be performed-to some extent-on...

We report results of a series of experiments that simulates trading in financial market. The specific format of our experiment allows to unambiguously measure the information content of the order flow and to disentangle the impact that risk attitudes and belief updating rules have on market...

We examine how financial theory and economic principles offer guidance and predictions about the organization of investments and asset allocation decisions given the structure of taxes in estate--planning situations. We provide insight about many of the conventional approaches to estate planning...

This paper presents a competitive rational expectations model of spot and forward prices for multiple commodities that can be stored and/or converted. As a result of the conversion option, an equilibrium theory of basis spreads across commodities is derived. This extends the "theory of storage"...
