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...

A principal faces an agent with frame-dependent preferences and designs an extensive-form decision problem with a frame at each stage. This allows the principal to induce dynamic inconsistency and thereby circumvent incentive compatibility constraints. We show that a vector of contracts can be...

We propose a tractable framework to introduce externalities in a screening model. Agents differ in both payoff-type and influence (how strongly their actions affect others). Applications range from pricing network goods to regulating industries that create externalities. Inefficiencies arise...

This chapter proposes an analysis of the role of advertising in the transmission of information in markets. It also describes how the economic analysis of informative advertising provides a satisfactory account of advertising practices and discusses the extent to which resorting to alternative...

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...

This paper provides a sufficient condition under which a general screening problem can be reduced, without the principal’s payoff loss, to one with the single crossing property. The sufficient condition requires the agent’s types to be ordered in a way that two marginal rates of substitution...

This work takes a closer look on the predominant assumption in usual lemon market models of having finitely many or even only two different levels of quality. We model a situation which is close to the classical monopolistic setting but admits an interval of possible quality values....

We incorporate a search-theoretic model of imperfect competition into an otherwise standard model of asymmetric information with unrestricted contracts. We develop a methodology that allows for a sharp analytical characterization of the unique equilibrium and then use this characterization to...

We study the informational role of prices in a stochastic environment. We provide a closed-form solution of the monopoly problem when the price imperfectly signals quality to the uninformed buyers. We then study the effect of noise on output, market price, information flows, and expected...

Network externality is a prominent feature of increasingly many products: the marginal payoff of one's consumption increases as his neighbors consume more. In- formation of network structure is important to the seller, but is often privately known to the buyers. We model a monopoly's optimal...
