This paper examines the relative burden of monopoly, measured using the equivalent variation, for different household income levels. Inequality measures are calculated using the complete distribution of equivalent incomes, for all households in the Australian household expenditure survey. The...

In this paper we present new estimates of the degree of welfare loss in Australian manufacturing for the period 1982/3 - 1984/5.

We examine two different models of manufacturer-retailer successive monopoly with retail demand uncertainty. In the first, both manufacturer and retailer are symmetrically uninformed about demand. Equilibrium exists if and only if the marginal costs of production and storage are sufficiently...

This paper constructs a simple repeated game model to analyze how industry outcomes alter if a regulated input monopolist is allowed to integrate into the downstream retail market. Integration helps overcome double marginalization-a feature well known in the existing literature. Unlike existing...

The access price is the charge that a network manager charges to other firms to carry traffic (whether it initiates it or finalizes it) through the network. This charge has gained importance as the regulation of formerly vertically integrated monopolies in some industries has opened them, at...

Antitrust authorities regard the possibility of post-merger entry and merger-generated efficiencies as two factors that may counteract the negative effects of horizontal mergers. This paper shows that in differentiated oligopolies with linear demand, all entry-inducing mergers harm consumer...

Mechanisms according to which private intermediaries or governments charge transaction fees or indirect taxes are prevalent in practice. We consider a setup with multiple buyers and sellers and two-sided independent private information about valuations. We show that any weighted average of...

We use cumulative reaction functions to compare long-run market structures in aggregative oligopoly games. We fi?rst compile an IO toolkit for aggregative games. We show strong neutrality properties across market structures. The aggregator stays the same, despite changes in the number of ?rooms...

This paper estimates the cost of using simple percentage fees rather than the broker optimal Bayesian mechanism, using data for real estate transactions in Boston in the mid-1990s. This counterfactual analysis shows that interme-diaries using the best percentage fee mechanisms with fees ranging...

This paper investigates the endogenous choice between price- and quantity-setting behaviour in a duopoly game where firms invest in product development first, and then play a marketing game later. Only in the initial R&D stage, the two firms set up a joint venture in order to share the costs of...
