We develop a model of vertical innovation in which firms incur a market entry cost and position themselves in the quality space. Once established, firms compete monopolistically, selling to consumers with heterogeneous tastes for quality. We establish existence and uniqueness of the pricing game...

We study an experimental market in which the structure of the information flows is endogenized. When making an offer, traders choose not only the price at which they are prepared to trade, but also the subset of traders they want to inform about the offer. This design allows for two extreme...

A general equilibrium model is considered with multiple divisible and multiple indivisible commodities.In models with indivisibles it is always assumed that an indivisible commodity, called money, is present that is used to transfer the value of certain amounts of indivisible goods.For these...

We study the structure of markets when traders are given the opportunity to create their own market, as on the internet.On the internet, public exchanges have in many cases been replaced by private exchanges.We use experiments to investigate possible reasons for the failure of public...

The tensions between books and book markets as expressions of culture and books as products in profit-making businesses are analysed and insights from the theory of industrial organisation are given.Governments intervene in the market for books through laws concerning prices of books, grants for...

This paper introduces optimal competition: the best form of competition in an industry that a competition authority can achieve under the information constraint that it cannot observe firms' effciency levels.We show that the optimal competition outcome in an industry becomes more competitive as...

We use a novel disaggregate sectoral euro area data set with a regional breakdown to investigate price changes and suggest a new method to extract factors from over-lapping data blocks. This allows us to separately estimate aggregate, sectoral, country-specific and regional components of price...

Most traditional Value at Risk models neglect market liquidity risk and hence only consider the market price risk (i.e. risk associated with holding a certain position). In order to fully capture the market risk associated to holding and trading a position, we first define market liquidity risk,...

This paper aims at investigating the presence of extra profits for the factoring companies operating with health sector credits. Using a panel data sample representative of Italian factoring companies, the analysis also examines, along with other factors, the determinants of corporate financial...

This paper studies the choice of cooperative versus non-cooperative R&D under incomplete information about the innovation size of the rival. It is assumed that the R&D outcome is stochastic and continuously distributed with a given mean and a constant variance. We show that the incentive for...
