The paradox of (Inter)net neutrality: An experiment on ex-ante antitrust regulation✰

2022

Abstract Net neutrality has been the most relevant and heavily debated Internet regulation policy of the last decade. Net neutrality aims to prohibit discrimination between data packages in terms of content, origin, destination, or type of equipment used. However, the Big Tech companies, sheltered by the net neutrality policy, have flourished. They now have the power to exclude minor companies, and therefore their contents, from the Internet market in de facto defiance of the net neutrality principle. Academic results regarding this net neutrality paradox are still ambiguous. To represent the current Internet market distortions and analyze a potential tool to adjust and strengthen the net n…

Vertical Separation v. Independent Downstream Entry in the Spanish Electricity Network: An Experimental Approach

2007

We present experimental results from a series of sessions organized using the Power Market simulator; a software designed to realistically replicate the Spanish Electricity Market. In the experiments reported here we compare the status quo to two alternative treatments which represent alternative market structures. In one of them, labeled as vertical separation, we assume that power generating firms and electricity distributors-endsuppliers belong to separate business groups. In the second, we study the effect of entry by independent end-suppliers. Both alternative scenarios dominate the status quo in terms of market efficiency, whereas the latter of them dominates the former.

Does hospital competition harm equity? Evidence from the English National Health Service

2011

Increasing evidence shows that hospital competition under fixed prices can improve quality and reduce cost. Concerns remain, however, that competition may undermine socio-economic equity in the utilisation of care. We test this hypothesis in the context of the pro-competition reforms of the English National Health Service progressively introduced from 2004 to 2006. We use a panel of 32,482 English small areas followed from 2003 to 2008 and a difference in differences approach. The effect of competition on equity is identified by the interaction between market structure, small area income deprivation and year. We find a negative association between market competition and elective admissions …

Using store level scanner data to improve category management decisions: Developing positioning maps

2009

This paper provides evidence of the usefulness of aggregated point-of-sale scanner data to infer the positioning of competing brands, providing valuable information for category management and hence facilitating decision making. Specifically, the authors propose a methodology to study the internal market structure based on market share models with latent heterogeneity when only macro-level time series data (not individual choices) are available. The proposed approach assumes a multidimensional decomposition, latent in the preference structure that is implicit to these types of models. By empirically applying this approach, the authors (1) simultaneously identify both latent dimensions of co…

Un análisis empírico del impacto de la regulación contable en el mercado de auditoría

2017

El objetivo de la presente tesis se centra en el estudio de la estructura del mercado de la auditoría así como en analizar el impacto económico que la regulación contable ejerce sobre determinados elementos del mercado de auditoría (honorarios y rentabilidad de las firmas de auditoría). A partir de la publicación del Reglamento europeo 1606/2002 se requirió a los grupos cotizados que formulasen sus estados financieros consolidados desde el 1 de enero de 2005, conforme a las Normas Internacionales de Información Financiera o NIIF. En España, la adaptación de las NIIF al resto de empresas, no se llevó a cabo hasta la aprobación del Nuevo Plan General Contable (NPGC) y del plan para pequeñas y…

Is the French mobile phone cartel really a cartel?

2009

International audience; France Telecom (FT), SFR and Bouygues Telecom (BT) have been fined by France's Conseil de la Concurrence (CC) for organizing a mobile phone cartel with stable market shares (one-half, one-third and one-sixth, respectively) and for directly exchanging commercial information. While not contesting the legal decision, it is argued here that the economic reasoning is flawed. (1) As the CC made much of the firms' stable market shares, we have first followed this line of reasoning by considering that the market shares are quotas under uniform costs. Even if there is a general incentive to form a monopolistic cartel, BT was too small for it to be worth its while to join it; it i…

Wine - investment: a profitable alternative investment or a simple long term pleasure?

2014

International audience; The purpose of this work is twofold: - to make a first historic analysis of performance through an investment in wine by comparing its performance with those that would have been possible to obtain at the same time by providing financial term investments; - to introduce the regional diversity of performance by considering the situation in the three selected geographic areas.

Allocating cost reducing investments over competing divisions

2007

This paper examines a three-stage model of divisionalization where, first, two parent firms create independent units, second, the parent firms allocate cost reduction levels over these units, and third, the resulting units compete in a Cournot market given their current costs of production. The introduction of the cost reduction phase is shown to reduce the incentives toward divisionalization severely, relative to other existing models. Namely, the scope for divisionalization in equilibrium reduces as the marginal cost of the cost reducing investment decreases, and eventually vanishes. A second-best welfare analysis shows that, for any given market structure, the equilibrium investment deci…
