The purpose of this Paper is to study the determinants of the concentration of ownership in a privatized, regulated firm. The discussion illustrates some aspects of the costs and benefits of different corporate systems. Privatized utilities are large firms with professional management: there is...

We develop a theoretical model of long-run investment decisions on capacity in the context of a liberalized electricity market. The sector's idiosyncrasies such as the uncertainty surrounding future supply and demand, as well as technological constraints, are explicitly modelled. The model is...

We develop a product market theory that explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each other’s trained employees and finally engage in imperfect product...

We investigate how various institutional settings affect a network provider’s incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out to be smaller under vertical separation than under vertical integration, though we also provide...

We examine how globalization affects firms’ incentives to provide general worker training. We consider a three-stage game. In stage 1, firms invest in productivity-enhancing training. In stage 2, they can make wage offers for each others’ workers. Finally, Cournot competition takes place....

We study substitution from fixed-line to mobile voice access, and the role of various complementarities that may influence this process.We use rich survey data on 160,363 households from 27 EU countries during 2005-2012. We estimate a discrete choice model where households may choose one or both...

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...

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...

We examine whether and how the allocation of financial transmission rights affects the behavior of electricity generators and electricity consumers with market power in the electricity market. The analysis recognizes that the ultimate allocation of rights is endogenous, depending both on whether...

We examine whether and how the allocation of physical rights to utilize congested transmission links affects the behavior of electricity generators and electricity consumers with market power in the electricity market. The paper extends the analysis of financial transmission rights contained in...
