Linear demand systems and quasi-linear quadratic utility models are widely used in
industrial economics. We clarify the link between the two settings and explain their exact …

We extend five principles of tax incidence under perfect competition to a general model of
imperfect competition. The principles cover (1) the independence of physical and economic …

Using information local to the premerger equilibrium, we derive approximations of the
expected changes in prices and welfare generated by a merger. We extend the pricing …

This paper lays out and extends a derivation of the “upward pricing pressure”(“UPP”) tool for
analyzing unilateral competitive effects of horizontal mergers on differentiated products that …

Interlinked transactions in which output prices are determined jointly with the terms of credit
are an important feature of many business relationships. In these instances, understanding …

This paper presents an experimental approach to measure competition in agricultural
markets, based on the random allocation of subsidies to competing traders. We compare …
