Evolutionary game theory provides a fresh perspective on the prospects that agents with heterogeneous expectations might eventually come to agree on a single expectation corresponding to the efficient markets hypothesis. We establish conditions where agreement on a unique forecast is stable, but...

We study the timing of leniency applications using a novel application of multi-spell discrete-time survival analysis for a sample of cartels prosecuted by the European Commission between 1996 and 2014. The start of a Commission investigation does not affect the rate by which conspirators apply...

We analyze the role of consumer expectations in a Hotelling model of price competition when products exhibit network effects. Expectations can be strong (stubborn), weak (price-sensitive) or partially stubborn (a mix of weak and strong). As a rule, the price-sensitivity of demand declines when...

This paper examines the interplay between financial market trading and product market competition. An entrant learns about product demand from trading volume in incumbent firm’s stock market before his entry decision. Without initial stake in incumbent firm, an informed investor trades on her...

We develop a model in which feedback effects from equity markets to firms' access to external finance allow uninformed traders to profit by short selling a firm's stock while going long on its competitors. Because this strategy distorts the investment incentives of the firm targeted by short...

We study the timing of leniency applications using a novel application of multi-spell discrete-time survival analysis for a sample of cartels that were prosecuted by the European Commission (EC) between 1996 and 2014. The start of an EC investigation does not affect the rate at which...

Traders differ in speed and their speed differences matter. I model strategic interactions induced when high frequency traders (HFTs) have different speeds in an extended Kyle (1985) framework. HFTs are assumed to anticipate incoming orders and trade rapidly to exploit normal-speed traders'...

This paper considers a dynamic duopoly market with strategic, price setting firms and an infinite set of fully rational, privately informed consumers who enter the market sequentially. I show that there exists a sequential equilibrium in which prices converge to their realized product qualities...

This paper examines the impact of public information in an economy where agents also have diverse private information. Since disclosures by central banks are an important source of public information, we are able to assess how the words of central bankers shape expectations, in addition to their...

We consider a 2-period model in which buyers can store the good - purchasing in advance of consumption so as to realize potential gains from inter-temporal price arbitrage - and examine the impact of market structure on the resulting inter-temporal price path and allocation. The main result is...
