We propose a model of discrimination in the market for mortgages. The model explains accepted loan applications and determines loan sizes and interest rates simultaneously. A competitive, and a discriminating monopoly version of the model are proposed. Offered interest rates and loan sizes are a...

This paper analyses the relation between competition and concentration in the banking sector. The empirical answer is given by testing a monopolistic competition model of bank branching behaviour on individual bank data at county level (départements and provinces) in France and Italy. We...

This paper empirically investigates the advertising competition in the French broadcast television industry within a two-sided market framework. We use a unique dataset on the French broadcast television market including audience, prices, and quantities of advertising of twenty-one TV channels...

In this paper, we formulate and estimate a structural model of demand to analyse the equilibrium effect of the RAN sharing by using cross-country panel data in 28 EU countries in years 2010-2020. Based on model estimates, our simulation analysis in Spain firstly provides a quantitative...

A substantial number of individuals remains unconnected to the Internet despite an increasing emphasis on infrastructure-based competition. This paper investigates the impact of shared telecom infrastructure on digital connectivity and inclusion using a new dataset on mobile tower sharing...

Do new digital consumption channels of music depress sales in old physical ones, or are they complementary? To answer this question, we exploit product-level variation in sales and prices of over 4 million products, observed weekly between 2014 and 2017 for the entire French market. A unique...

This survey is devoted to the statistical analysis of duration models and point processes. The first section introduces specific concepts and definitions for single-spell duration models. Section two is devoted to the presentation of conditional duration models which incorporate the effects of...

In this paper we propose a novel method to construct confidence intervals in a class of linear inverse problems. First, point estimators are obtained via a spectral cut-off method depending on a regularisation parameter », that determines the bias of the estimator. Next, the proposed confidence...
