The financial crisis drew attention to the crucial role of transparency and the independence of financial certification intermediaries, in particular, statutory auditors. Now any anticompetitive practice involving coordinated increases in prices or concomitant changes in quality that impacts...

We formulate and estimate a structural model for travel demand, in which users have heterogeneous preferences and make their transport decisions considering the network congestion. A key component in the model is that users have incomplete information about the preferences of other users in the...

This paper investigates various options for the organization of the railway industry when network operators require the access to multiple national networks to provide international (freight or passenger) transport services. The EU rail system provides a framework for our analysis....

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...

Since the publication by Williamson (1968) of his seminal paper on antitrust there has been a growing recognition by regulators of the need to assess trade-offs between merger-related efficiency gains and merger-induced increases in market power. This paper addresses that need by presenting a...

This paper first discusses how the market is delineated in some recent antitrust cases in the printed media industry. It evaluates the extent to which the main features of the industry are incorporated into the analysis and affect market definition. In addition we argue that an econometric...

We describe a pair of subadditivity tests that can be used to evaluate the technological feasibility of separating a vertically integrated network monopoly into a common infrastructure component and competing operating components. We implement the tests with a Generalized McFadden cost function...

Most empirical studies that evaluate motives and gains in M&A conclude that acquirers at best do not lose from the deal while targets obtain positive gains. With a database containing merging firms’ characteristics and final bids, we propose a structural approach to infer acquirers’ gains...

The objective of the paper is to elaborate a simulation model to analyse inter and intra-modal competition in the transport industry, based on game theory models. In our setting, consumers choose a transport mode and an operator to travel on a given city-pair; operators strategically decide on...

We consider a framework of contractual interactions between public transport authorities and transport operators. We estimate simultaneously the contract choice by the authorities and the effect of regulation on the cost-reducing activity of the operators. We test whether the current regulatory...
