We analyze a model of monopolistic price discrimination where only some consumers are originally sufficiently informed about their preferences, e.g., about their future demand for a utility such as electricity or telecommunication. When more consumers become informed, we show that this benefits...

The welfare effects of third-degree price discrimination are known to be negative when demand functions are linear, marginal cost is constant and all markets are served. This paper shows that discrimination lowers welfare for a more general class of demand functions. Demand varies across markets...

I consider a retailer who sells a new product over two periods: advance and regular selling seasons. Experienced consumers learn their valuations for the product in the advance selling season, while inexperienced consumers learn only when the product becomes available in the regular selling...

I characterize the menu of bundles (price-quantity combinations) offered by a monopolist when consumers can buy several bundles, share bundles with others, or do both, in a two-type setting. I find that although perfect arbitrage prevents any price discrimination, partial arbitrage in the form...

We compare four approaches to network neutrality and network management regulation in a two-sided market model: (i) no variations in Quality of Service and no price discrimination; (ii) variations in Quality of Service but no price discrimination; (iii) variations in Quality of Service and price...

Carrying multiple brands and holding periodic sales are two common marketing strategies for sellers with market power. One puzzle is that sellers often employ diverse strategies in terms of using these two tools. This paper offers an explanation to this puzzle by providing a simple framework to...

According to current data regulations, consumers are mobile among different markets, which endogenizes market segmentation. When accommodating such strategic interactions, a segmentation is stable if no consumer can find a profitable deviation to another market. In every stable market...

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...

This paper solves a simple model of third-degree price discrimination assuming two independent linear demands and discusses the effects of price discrimination on monopoly profit, consumer surplus, and social welfare. In addition, using a simple model, this paper shows that the probability that...

Many companies supplying consumption goods and services provide their shareholders with price discounts. This paper presents a simple model describing shareholder discounts and consequent market equilibrium. It is found that shareholder discounts resemble many features of two part tariffs. The...
