COST stands for Cooperation in Science and Technology and is the longest running network funding organisation in Europe. Within the COST networks, Action D42 is dedicated to the role of the indoor environment on the behaviour of the materials present in archives, libraries and museums. Under storage, use and or exhibition. The indoor environment consists of many components able to deteriorate o...

The present article considers the situation in which the buyer’s taste and budget are his private information. In this multi-dimensional setting, we study the optimal mechanism through a canonical mechanism in the traditional one-dimensional context: a function of one variable, the buyer’s taste. In our multi-dimensional context, however, this is an indirect mechanism. We investigate the effect...

Lupus-prone, anti-DNA, heavy (H) chain "knock-in" mice were obtained by backcrossing C57BL/6 mice, targeted with a rearranged H chain from a VH11(S107)-encoded anti-DNA hybridoma (D42), onto the autoimmune genetic background of New Zealand Black/New Zealand White (NZB/NZW) F1 mice. The targeted female mice developed typical lupus serologic manifestations, with the appearance of transgenic IgM a...

Theoretically and experimentally, we generalize the analysis of acquiring a company (Samuelson and Bazerman 1985) by allowing for competition of both, buyers and sellers. Näıvety of both is related to the idea that higher prices exclude worse qualities. While competition of näıve buyers increases prices, competition of näıve sellers promotes efficiency enhancing trade. Our predictions are teste...

We extend Armstrong’s [1] result on exclusion in multi-dimensional screening models providing support for the view that the result holds true in a large class of models. We first relax some of the strong technical assumptions he imposed and provide alternative su cient conditions for exclusion not relying on any form of convexity. We then proceed to show that exclusion obtains generically. We i...

We consider a general scheme to construct Bayesian incentive-compatible mechanisms using a suitable ‘variable mechanism parametrization.’ The key idea is to perturb a given direct mechanism, which might not be truth revealing, introducing sufficient variability as a function of agents’ announcements to generate incentives for truthful revelation. We discuss a variable-price auction in a general...

This paper studies a model of product variety with flexible manufacturers when, contrary to prior work, atomistic entry occurs prior to horizontal integration. In this model, more lax antitrust laws that allow for fewer and more concentrated merged firms lead to a greater extent of excess entry. Optimal policy permits no horizontal mergers when demand is perfectly inelastic, but may permit some...

The Enam null mice appear to be smaller than wild-type mice, which prompted the hypothesis that enamel defects negatively influence nutritional intake and bodyweight gain (BWG). We compared the BWG of Enam(-/-) and wild-type mice from birth (D0) to Day 42 (D42). Wild-type (WT) and Enam(-/-) (N) mice were given either hard chow (HC) or soft chow (SC). Four experimental groups were studied: WTHC,...

Motivated by recent antitrust cases in markets with zero-pricing, we develop a leverage theory of tying two-sided markets. In the presence nonnegative price constraint, Chicago school critique tie-ins fails to hold. independent products case, provides mechanism circumvent constraint tied market without inviting aggressive responses rival firm. complementary “price squeeze” cannot be used extrac...
