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 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...

This paper is concerned with how a front-running high-frequency trader (HFT) influences the large trader: whether and under what conditions the latter is harmed or benefited. We study, in the extended Kyle's model, the interactions between a large informed trader and an HFT who can predict the...

This paper focuses on the legal monopoly for sporting bets in Germany. We analyze the pricing behavior of the monopolist ODDSET and find that typical pricing inefficiencies on betting markets are reinforced under the monopoly. This result in conjunction with the decreasing tax revenue may...

In this paper, the interactions between a large informed trader (IT, for short) and a high-frequency trader (HFT, for short) who can anticipate the former's incoming order are studied in an extended Kyle's model. Equilibria under various specific situations are discussed. We find that, in...

Entry into a network industry is modeled, focusing on consumers' expectations formation. Equilibrium expectations are endogenous and they depend on prices, acting as a coordination device among consumers. The model is able to account for aggressive pricing policies by the incumbent and by the...

We address the issue of risk aversion in a competitive equilibrium when some buyers engage in learning and information is conveyed through the price system. Specifically, since the learning process yields uncertainty, we study the effect of risk aversion on the equilibrium outcomes of the model,...

We study the issue of integrating real and financial decisions in a monopoly firm with risk-averse decision-makers. To that end, we combine the decisions of the firm and of the shareholders in a very simple but robust model, with uncertainty in the real market and CARA preferences. We show the...

The formation of consumer expectations for digital products affects competition between digital platforms that offer competing products. Unfair competition may occur if the competitive outcome is influenced my misled expectations, notably if the company that wins the competition either misled...

We present a diagrammatic and step-by-step analysis of price signaling quality. Because quality is a continuum on the real positive line, out-of-equilibrium beliefs need not be specified, i.e., every positive price is a positive outcome in equilibrium. We first study the behavior of the monopoly...
