Current Department of Justice merger guidelines assume that merging the capacities of two firms will translate into an equivalent increase in market shares. Size matters. Economic theory asserts size is determined by marginal revenue and marginal cost not capacity. Size does not matter. In this...

The two central pricing rules contained in most antitrust laws are prohibitions of below-cost pricing and prohibitions of discriminatory pricing. This article shows that the rule against discriminatory pricing may actually induce firms to charge exclusionary below-cost prices, even in the...

I investigate an asymmetric duopoly where a public enterprise must supply the demand it faces, while a private enterprise has no such obligation. I show that such an asymmetric regulation yields the first-best outcome (Walrasian equilibrium).

This paper identifies a new sufficient condition for a prudent agent to have positive precautionary saving in the presence of labor income and interest rate risks of any size. We also provide three economic interpretations for this condition focusing respectively on the marginal effect of saving...

This paper generalizes two theorems in Campbell and Walker (1990), which is based on weak upper continuity. A new property, called partial upper continuity, is shown to be sufficient for representation and existence of a maximal element. Noting that transfer weak upper continuity (Tian and Zhou,...

When individuals compare themselves to those with the same wage-rate, status concerns–Keeping up with the Joneses–lead individuals to work who otherwise would have chosen not to, and, for them, well-being is a decreasing function of the wage rate.

We provide two methods to compute the largest subset of a set of observations that is consistent with the Generalised Axiom of Revealed Preference. The algorithm provided by Houtman and Maks (1985) is not computationally feasible for larger data sets, while our methods are not limited in that...

I put forward a concise and intuitive formula for the calculation of the valuation for a good in the presence of the expectation that further, related, goods will soon become available. This valuation is tractable in the sense that it does not require the explicit resolution of the consumer’s...

We consider the widely used multinomial logit model with i.i.d. Gumbel random terms. Transition choice probabilities, i.e. probabilities of choosing alternative i in the first choice and alternative j in the second, are available in analytic form in the two extreme cases where the random terms...

Three types of demand functions are central to contemporary consumer theory: the Marshallian, the Hicksian, and the Frischian demand functions. This paper presents a systematic definition of the analytical relationships amongst these demand functions under the maintained hypothesis that the...
