A model-free methodology is used for the first time to estimate a daily volatility index (VIBEX-NEW) for the Spanish financial market.We use a public data set of daily option prices to compute this index and showthat daily changes in VIBEXNEW display a negative, tight contemporaneous...

Purpose – The aim of this paper is to analyze the compatibility between entrepreneurial and social attitudes. Specifically, it seeks to analyze whether subjects with a more developed economic entrepreneurial attitude exhibit a less social attitude. Design/methodology/approach – The...

This paper explores experimentation and learning in asymmetric duopoly markets with product differentiation and demand uncertainty. We define the concepts of strategic substitutability and strategic complementarity in information and we show how both the mode of information competition and the...

We analyze the effect of industrial espionage on entry deterrence. We consider a monopoly incumbent who may expand capacity to deter entry, and a potential entrant who owns an Intelligence System. The Intelligence System (IS) generates a noisy signal based on the incumbentʼs actions. The...

This paper constructs the equilibrium for a specific code that can be seen as a “universal grammar” in a class of common interest Sender–Receiver games where players communicate through a noisy channel. We propose a Senderʼs signaling strategy which does not depend on either the game...

Statistical information is crucial for managerial decision making. The decision-making literature in psychology and mathematical cognition documents how different statistical formats can facilitate certain types of decisions. The present analysis is the first of its kind to assess the impact of...

We show the role of unmediated talk with computational complexity bounds as both an information transmission and a coordination device for the class of two-player games with incomplete information and rational parameters. We prove that any communication equilibrium payoff of such games can be...

We examine a monopoly facing an uncertain demand and maximizing profits over a two-period horizon. Conditions are developed under which the firm will find it optimal to "experiment," or adjust initial prices or quantities away from their myopically optimal level in order to increase the...
