This paper shows that Hausman-McFadden and related tests for the multinomial logit model are not informative about failure of IIA, but only about specification error in the deterministic part of the utilities attached to choice alternatives. It is shown that the multinomial logit cannot be...

Reducing meat consumption has become a global policy target due to rising environmental, health, and animal welfare concerns. We provide novel evidence on how price change in real life affects grocery shopping behavior in the Netherlands. We focus on price-induced behavioral response among major...

This paper considers specification tests for the multinomial logit model if alternative-specificconstants are used to absorb the impact of omitted variables in the deterministic parts of theutilities. It finds that such tests then do not have any power. This implies that such tests have nopower...

In its landmark ruling in Illinois Brick Co. v. Illinois in 1977, the U.S. Supreme Court restricted standing to sue for recovery of antitrust damages to direct purchasers. However, antitrust damages are typically (in part) passed on to intermediaries lower in the chain of production and...

This paper studies an intermediated market operated by middlemen with high inventory holdings. I present a directed search model in which middlemen are less likely to experience a stockout because they have the advantage of inventory capacity, relative to other sellers. The model explains why...

This paper presents a model of second-degree price discrimination and inter-group effects to describe the full-service pricing behaviour in the passenger aviation market. Consumer heterogeneity is assumed on both a horizontal and a vertical dimension, while various distinct market structures,...

This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode by which an intermediary holds inventories...

In its landmark ruling in Illinois Brick Co. v. Illinois, the U.S. Supreme Court restricted standing to sue for recovery of damages suffered from a breach of federal antitrust law to direct purchasers only. Even though typically antitrust injury is, at least in part, passed on to firms lower in...

This paper investigates infrastructure investment in markets where regulation is subject to varying degrees of manipulation by elected politicians. Based on a model of price regulation in a market with increasing demand and long-term returns on investment we construct a multi-period game between...

We extend the models in ("Competition in two-sided markets" of Armstrong (2006, Rand Journal of Economics) by adding within-group externalities. In the monopoly and duopoly cases, positive within-group externalities reduce the price of the own group. Negative externalities have an opposite price...
