Ranking have become increasingly popular on markets for study programs, restaurants, wines, cars, etc. This paper analyses the welfare implication of such rankings. Consumers have to make a choice between two goods of unknown quality with exogenous presence or absence of an informative ranking....

When is the modeller introducing more error when analysing a Cournot market with private cost information - when ignoring market power or when ignoring the impact of incomplete information? Is the welfare loss at the market outcome driven by private information or by market power? The answer,...

This Paper uses representative firm level panel data of 1,701 Bulgarian and 2,047 Romanian manufacturing firms to estimate market power (i.e. price-cost margins) and to analyse how these are affected by privatization and increased competitive pressure. In contrast to earlier work that analyses...

We generalize von der Fehr and Harbord's (1993) multi-unit auction model for the case of a deterministic demand allowing for any technology mix and elastic demand in order to account for demand side bidding. We obtain a general characterization of the equilibrium and show that the Cournot model...

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...

We specify several variants of a structural econometric model explaining mortgage interest rates and loan sizes simultaneously. The models are estimated by simultaneous equation methods with a sample of loan files originated from a French mortgage lender. They yield estimates of the...

We study liquidity transfers between banks through the interbank borrowing and asset sale markets when (i) surplus banks providing liquidity have market power, (ii) there are frictions in the lending market due to moral hazard, and (iii) assets are bank-specific. We show that when the outside...

In this paper we apply the Bresnahan-Lau (1982) model to test for market power in the European distribution of salmon. In this particular setting, the model also incorporates a test of whether dumping takes place over time. Utilising data at the import level, derived demand equations are...

A model is presented of a uniform price auction where bidders compete in demand schedules; the model allows for common and private values in the absence of exogenous noise. It is shown how private information yields more market power than the levels seen with full information. Results obtained...

In this paper we specify and estimate a structural model which accounts for competition in two variables: capacity and prices. The model has a two-stage set-up. In the first stage firms make capacity decisions followed by a product-differentiated, price-setting game in the second stage. Since...
