We propose a model of data provision and data pricing. A single data provider controls a large database that contains information about the match value between individual consumers and individual firms (advertisers). Advertisers seek to tailor their spending to the individual match value. The...

We analyze data pricing and targeted advertising. Advertisers seek to tailor their spending to the value of each consumer. A monopolistic data provider sells cookies -- informative signals about individual consumers' preferences. We characterize the set of consumers targeted by the advertisers...

We develop a model of data pricing and targeted advertising. A monopolistic data provider determines the price to access "cookies," i.e., informative signals about individual consumers' preferences. The demand for information is generated by advertisers who seek to tailor their spending to the...

This paper examines a mechanism of liquidity-preference fluctuations caused by changes in people's belief about a random liquidity shock. When observing the shock, they rationally update their belief so that the shock probability is higher; consequently they raise liquidity preference and reduce...

We examine a foreign firm's choice between exporting and foreign direct investment (FDI) under country-specific cost uncertainty. Unlike exporting, FDI exposes foreign and home firms to common shocks. This results in a correlation of strategies, harming the firms. However, the exposure to common...

We examine the role of cost uncertainty in a firm's choice between exporting and foreign investment in oligopolistic industry. We consider both foreign direct investment and an international joint venture, and allow country-specific and firm-specific cost uncertainty. Unlike exporting, either...

When a durable good of uncertain quality is introduced to the market, some consumers strategically delay their buying to the next period with the hope of learning the unknown quality. We analyze the monopolist's pricing and waiting strategies when consumers have strategic delay incentives. We...

This paper explores the question whether boundedly rational agents learn to behave optimally when asked to voluntarily contribute to a public good. The decision process of individuals is described by an Evolutionary Algorithm. We analyze the learning process of purely and impurely altruistic...

Dieser Beitrag gibt einen Überblick über Ansatzpunkte und Möglichkeiten zur Integration von Lernprozessen in volkswirtschaftliche Fragestellungen. Es werden alternative Methoden vorgestellt, individuelle aber auch gesellschaftliche Lernenvorgänge in ökonomischen Modellen zu erfassen.

Das Papier untersucht, wie Erwartungsbildung mit Hilfe neuronaler Netze modelliert werden kann. Die Grundlage bildet ein Cobweb-Modell, in dem Firmen Preiserwartungen auf Basis eines Feedforward-Netzes bilden. Zunächst wird anhand von Simulationen gezeigt, daß Firmen durch neuronale...
