2. Experimental methods (Statistical analysis) (P 1859, L13-19 of the right column) Dunnett’s multiple comparison test was performed for the inter-group comparison of QOL score. To examine whether the effect of b240 on QOL score was independent of common cold experience, we used generalized linear models in which we entered changes in score (Δpost – pre) as the target variable, and group (place...

We consider a duopoly industry with two separate firms each selling an indivisible product. The joint consumption of these goods has a specific value for the consumers which exceeds the mere addition of utilities when products are consumed in isolation: the higher this excess, the larger the complementarity between the goods. We analyse price equilibria in this market as related to the degree o...

A patent owner is entitled to recover any additional profits that would have been earned but for infringement. This paper suggests the use of an adaptation of merger simulation to assess lost profits in patent infringement cases. A model of the industry with infringement is calibrated to observed prices and quantities and estimated demand elasticities. Lost profits are then estimated by calcula...

This paper formalizes an empirically implementable framework for the definition of local antitrust markets in retail markets. This framework rests on a demand model that captures the trade-off between distance and pecuniary cost across alternative shopping destinations within local markets. The paper develops, and presents estimation results for, an empirical demand model at the store level for...

Using a model of vertical product differentiation, we show under what institutional circumstances welfare gains will be maximized as economies integrate and harmonize labeling and certification policies for credence goods. Specifically, we show that harmonized mandatory, exclusive discrete labeling will not maximize the gains from economic integration, i.e., the choice of labeling regime can ha...

The combinatorial clock auction has become popular for large-scale spectrum awards and other uses, replacing more traditional ascending or clock auctions. We describe some surprising properties of the auction, including a wide range of ex post equilibria with demand expansion, demand reduction, and predation. Our results obtain in a standard homogeneous good setting where bidders have well-beha...

PURPOSE The aim of this study was to investigate the correlation between bone mineral density (BMD) and arterial stiffness as a preclinical atherosclerosis criterion. MATERIALS AND METHODS Carotid and femoral artery Doppler ultrasonography and arterial stiffness measurements were performed on 113 female patients referred for BMD measurements. RESULTS The cross-sectional compliance and cross...

We de…ne pessimistic, respectively optimistic, investors as CEU (Choquet expected utility) decision makers who update their pessimistic, respectively optimistic, beliefs according to a pessimistic (Dempster-Shafer), respectively optimistic, update rule. This paper then demonstrates that, in contrast to optimistic investors, pessimistic investors may strictly prefer investing in an illiquid asse...

This paper provides a theory of endogenous network formation in over-the-counter markets based on trade competition and inventory risk balancing. A core-periphery network structure arises as an equilibrium outcome. A small number of agents emerge as core dealers to intermediate among a large number of peripheral agents. The equilibrium level of dealer entry (the size of the core) depends on the...
