The aim of this Paper is to evaluate simultaneously market power and the incentives faced by carriers to improve efficiency, taking into account the regulatory changes that have affected the European airline industry. We construct and estimate a model that includes demand, capacity, and cost...

The renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts. However, assessing the cost of such renegotiation remains an open issue from an empirical viewpoint. To address this question, we fit a structural...

We consider an empirical model of worldwide airlines’ alliances that we apply to a large set of companies for the period 1995-2000, with special attention to US and EU carriers. From the estimation of a cost, capacity and demand system that accounts for cross-price elasticities, we attempt to...

We study the effect of entry on costs and competition in the Portuguese mobile telephony industry. We construct and estimate a model that includes demand, network, and cost equations. The latter accounts for inefficiency and cost reducing effort. We show that failure to account for cost reducing...
