The condition for when a price control increases consumer welfare in perfect competition is tighter than often realised.  When demand is linear, a small restriction on price only increases consumer surplus if the eleasticity of demand exceeds the elasticity of supply; with log-linear or...

A budget-constrained buyer wants to purchase items from a shortlisted set. Items are differentiated by quality and sellers have private reserve prices for their items. Sellers quote prices strategically, inducing a knapsack game. The buyer's problem is to select a subset of maximal quality. We...

In this paper the dynamical effects of public environmental policies are investigated in a Cournot duopoly with heterogeneous expectations in a context of limited rationality. It is shown that the introduction of upper limits to emissions always tends to destabilise and generate a chaotic market...

This paper analyses the effects of a downstream merger in a differentiated duopoly under price competition and plant-specific unions. We show, in contrast with the preceding literature, that the standard welfare results may be reversed: a downstream merger may increase consumer surplus and...

Abstract Motivated by the widespread presence both of decentralised unions and cross-participation at ownership level (for instance in Japan and US), this paper aims at investigating whether the conventional wisdom that a reduction in the degree of product differentiation (which increases...

In this paper we revisit the issue of the scope of bargaining between firms and unions. It is shown that an agreement between p arties on the bargaining agenda may endogenously emerge only on the Efficient Bargaining arrangement, provided that union’s power is not too high.

Can a merger from duopoly to monopoly be detrimental for profits? This paper deals with this issue by focusing on the interaction between decreasing returns to labour (which imply firms’ convex production costs) and centralised unionisation in a differentiated duopoly model. It is pointed out...

This paper analyses the effects of a downstream merger in a differentiated duopoly under price competition and firm-specific unions. In contrast with the acquired wisdom, we show that a downstream merger may increase overall welfare when products are sufficienly substitutes and unions are...

We analyse the dynamics of a banking duopoly game with heterogeneous players (as regards the type of expectations’ formation), to investigate the effects of the capital requirements introduced by international accords (Basel-I in 1988 and more recently Basel-II and Basel-III), in the context...
