We examine the impact of multiproduct nonlinear pricing on profit, consumer surplus and welfare in a duopoly. When consumers buy all their products from one firm (the one-stop shopping model), nonlinear pricing leads to higher profit and welfare, but usually lower consumer surplus, than linear pricing. By contrast, in a unit-demand model where consumers may buy one product from one firm and ano...

Previous research indicates that consumers often exhibit surprisingly poor knowledge of product prices. The present study investigates whether price knowledge, as measured by reference price accuracy, is related to price-sensitivity as measured by the price-elasticity of demand. We hypothesize that consumers are most knowledgeable regarding the prices of goods for which demand is most price-ela...

This paper extends the standard model of bundling to allow products to be substitutes and for products to be supplied by separate sellers. Whether integrated or separate, …rms have an incentive to introduce bundling discounts when demand for the bundle is elastic relative to demand for stand-alone products. Separate …rms often have a unilateral incentive to o¤er inter-…rm bundle discounts, alth...

This paper investigates how interest rates on liquid assets and excess returns on risky assets are determined when only safe assets can be used as liquid assets when waiting for an informative signal of future payoffs. In particular, we carefully differentiate between a demand for liquid assets while waiting for new information and a demand for safe assets for precautionary reasons. Employing K...

JEL classification: F1 F12 We show theoretically and confirm empirically that domestic productivity has a significant impact on the demand for foreign varieties under the assumption that domestic and foreign varieties are imperfect substitutes. In particular, the demand for imported varieties ismore elastic for countries with comparative advantage. For an average good facing a median trade barr...

Previous research, assuming linear pricing, has argued that telecommunications networks may use a high access charge as an instrument of collusion. I show that this conclusion is difficult to maintain when operators compete in nonlinear pricing: (i) As long as subscription demand is inelastic, profits can remain independent of the access charge, even when customers are heterogeneous and network...

This paper deals with the following question associated with congestion pricing in a general network with either fixed or elastic travel demand: what is the maximum efficiency loss of a general second-best pricing scheme due to inexact marginal-cost pricing in comparison with the first-best pricing or system optimum case? A formal answer to this question is provided by establishing an inefficie...

There is evidence that suppliers have private information about their customers’ credit risk. Yet, interest rates in trade credit markets are usually industry-not-firm specific. Why? If the demand for intermediate products is inelastic, suppliers should raise interest rates until they reach their customers’ outside option. By definition, this outside option cannot reflect information that is pr...

This paper presents a two-country model in which consumers’ utility from tradable goods depends on their consumption of complementary goods and services. The model is consistent with the stylized fact that markups are higher in rich countries: In countries with more complementary goods and services consumer demand is less elastic, enabling monopolistically competitive firms to charge higher pri...

During bouncing gaits such as hopping and running, leg muscles generate force to enable elastic energy storage and return primarily from tendons and, thus, demand metabolic energy. In an effort to reduce metabolic demand, we designed two elastic leg exoskeletons that act in parallel with the wearer's legs; one exoskeleton consisted of a multiple leaf (MLE) and the other of a single leaf (SLE) s...
