We study a two-player, zero-sum, stochastic game with incomplete information on one side in which the players are allowed to play more and more frequently. The informed player observes the realization of a Markov chain on which the payoffs depend, while the non-informed player only observes his...

We study a class of symmetric strategic experimentation games. Each of two players faces a (exponential) two-armed bandit problem, and must decide when to stop experimenting with the risky arm. The equilibrium amount of experimentation depends on the degree to which experimentation outcomes are...

We analyze a toy class of two-player repeated games with two-sided incomplete information. In effect, two players are facing independent decision problems and each of them holds information that is potentially valuable to the other player. We study to what extent, and how, information can be...

Speculators can discover whether a signal is true or false by processing it but this takes time. Hence they face a trade-off between trading fast on a signal (i.e., before processing it), at the risk of trading on a false positive, or trading after processing the signal, at the risk that prices...

Aggregate art price patterns mask a lot of underlying variation — both in the time series and in the cross-section. The authors argue that, to increase our understanding of the market for aesthetics, it is helpful to take a micro perspective on the formation of art prices, and acknowledge that...

High frequency arbitrage opportunities arise when the price of one asset follows, with a lag, changes in the value of another related asset due to information arrival. These opportunities are toxic because they expose liquidity suppliers to the risk of being picked off by arbitrageurs. Hence,...

By focusing on the highly innovative retail market for structured products, we investigate the drivers of financial complexity. We perform a lexicographic analysis of the term sheets of 55,000 retail structured products issued in Europe since 2002. We observe that financial complexity has been...

In this paper, we use the investment fraud of Bernard Madoff to inquire into the production of trust in the context of financial markets. Drawing upon empirical data related to U.S. individual investors (interviews and letters) as well as documentary material, we investigate the mechanisms...

In this paper, the authors study the possibility of controlling asset price volatility through financial innovation in a three-period finite competitive exchange economy with incomplete financial markets and retrading.

This paper provides a survey of recent changes in the market microstructure of the 5 largest European Stock Exchanges. We first provide a brief statistical overview of European equity markets. Then we discuss how the introduction of the Investment Services Directive and the development of...
