In this paper we examine the design of nonlinear prices by a multiproduct monopolist who faces customers with multidimensional but correlated types. We show that the monopoly can exploit the correlations between consumers' types to design pricing mechanisms that fully extract the surplus from...

Italian Abstract: Vengono calcolate le tariffe in due parti ottenute mediante la discriminazione di prezzo monopolistica di I, II e III grado. I tre casi derivano da diverse funzioni obiettivo del monopolista e dai diversi vincoli, dovuti ai diversi gradi di informazione del monopolista rispetto...

Italian Abstract: Sono esaminati i casi di un Principale ed un Agente, in cui il principale possa agire in contesto di monopolio o di concorrenza perfetta, e l'informazione possa essere completa o meno. In particolare per informazione completa viene considerato il caso in cui sia l'azione che il...

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...

We analyze how speculative financial innovation affects stock prices, risk premiums, market liquidity, and investor welfare in an economy with heterogeneous beliefs. When investors disagree about the covariance of the newly introduced stocks with the original stocks, we show that financial...

This article describes ways to use original texts in the National Russian Corpus as well as news texts for teaching Russian as a foreign language. Two-year work of a scientific group of Higher School of Economics (Nizhny Novgorod-Moscow), which is called CorpLings is analyzed. Special attention...

We provide a dynamic, game-theoretic model to examine a firm’s quality and pricing decisions for a new experience good. Early consumers do not observe product quality prior to purchase but can learn it after purchase and share that product-quality information with later consumers, for example,...

If a monopoly supplies a perishable good, such as tickets to a performance, and is unable to price discriminate within a period, the monopoly may benefit from the potential entry of resellers. If the monopoly attempts to intertemporally price discriminate, the equilibrium in the game among...

The standard profit-maximizing multi-unit auction can be represented as the Vickrey-Groves-Clarke mechanism in which the seller manipulates his reservation supply curve. The optimal supply curve depends on the distribution from which the buyers' valuations are drawn. However, when this...

This paper argues that the strategic use of debt favours the revelation of information in dynamic adverse selection problems. Our argument is based on the idea that debt is a credible commitment to end long term relationships. Consequently, debt encourages a privately informed party to disclose...
