I study a model of oligopolistic competition in which consumers search for prices, but have no idea about the underlying price distribution. Consumers’ behaviour satisfies four consistency requirements such that beliefs about the underlying distribution maximize Shannon entropy. I derive the optimal stopping rule and equilibrium price distribution of the model. Unlike in Stahl (1989), the expected price is decreasing in the number of firms. Moreover, consumers can benefit from being uninformed, if the number of firms is sufficiently large.

In this article, I examine a model of oligopolistic competition in which consumers search for prices but have no knowledge of the underlying price distribution. The consumers' behaviour satisfies four consistency requirements and, as a result, their beliefs about the underlying distribution maximise Shannon entropy. I derive the optimal stopping rule and equilibrium price distribution ...

Since Telser (1960), there is a well-established argument that a competitive market will not provide service due to free-riding. We show that with search frictions, the market may well provide service if the cost of doing so is not too large. Any market equilibrium with service provision has two or more firms providing service, implying ...

We study how a monopoly manufacturer optimally manages her contractual relations with retailers in markets with consumer search. By choosing wholesale prices, the manufacturer affects the degree of competition between retailers and the incentives of consumers to search. We show that depending on whether or not the manufacturer can commit to her price decisions and ...

Following a series of works on capital growth investment, we analyse log-optimal portfolios where the return evaluation includes ‘weights’ of different outcomes. The results are twofold: (A) under certain conditions, the logarithmic growth rate leads to a supermartingale, and (B) the optimal (martingale) investment strategy is a proportional betting. We focus on properties of the ...

The paper is devoted to the economic analysis of rationality in the tradition of Harvey Leibenstein: the authors perceive rationality as “calculatedness” when making decisions, while the degree of this “calculatedness” is interpreted as a variable. Thus, this approach does not correspond to the generally accepted neoclassical interpretation of rationality, according to which rationality is ...

This article considers the relationships among meaning generation, selection, and the dynamics of discourse from a variety of perspectives ranging from information theory and biology to sociology. Following Husserl's idea of a horizon of meanings in intersubjective communication, we propose a way in which, using Shannon's equations, the generation and selection of meanings from a ...

This survey analyzes central ideas and the current state of the economic theory of learning in games. In game theory learning can be thought of as both an alternative to equilibria and as a way to better understand the nature of equilibria. Outside of game theory, theory of learning shows economic theory (for example, the ...

The last market crash of 2008-2009 showed that the construction sphere is one of the most fragile subject to the crisis effect. The destructive effect of this crash resulted in substantial decrease in mortgage lending, price index, capital investment, and in growth of the cost level. As the construction industry remains strategically important, the eruption ...
