How to regulate wholesale access on next generation access (NGA) networks is probably the most pressing issue faced by European telecoms regulars today. The lack of actual competitive restraint from cable operators precludes the replication of US-like regulatory forbearance, as it might lead to...

This paper is concerned with stochastic demand systems for continuous choices that arise from structural random utility models. It examines under which nonparametric conditions on the structural random utility specification the implied reduced form model is nonsingular and invertible. For...

This paper considers the micro-econometric analysis of discrete choice problems in which the choice set is strategically pre-selected by a third-party advisor or expert. It delineates measures of efficiency loss arising from (i) the sets of relevant choice attributes being imperfectly aligned...

This paper analyzes equilibria in sequential take-it-or-leave-it sales when demand is stochastic. It is shown that equilibria in this sales mechanism, unlike in sequential auctions, trade-off allocative efficiency and competing buyers' opportunities to acquire an item to be sold, permitting...

This paper presents a structural econometric framework for discrete and continuous consumer choices in which unobserved intrapersonal and interpersonal preference heterogeneity is modeled explicitly. It outlines a simulation-assisted estimation methodology applicable in this framework. This...
