Consumers are commonly required to subscribe to particular tariff options before uncertainty regarding their future purchases gets resolved. Since the general comparison of welfare performance of different pricing mechanisms is ambiguous, this paper empirically evaluates the expected welfare associated to standard nonlinear pricing and optional tariffs by using information directly linked to th...

We characterize the optimal dynamic price policy of a monopolist who faces “viscous” demand for its services. Demand is viscous if it adjusts relatively slowly to price changes. We show that with the optimal policy the monopolist stops short of achieving 100% market penetration, even when all of the consumers have the same long-run willingness to pay for the service. Furthermore, for certain pa...

We document the existence of pricing styles in the concert industry. Artists differ in the extent to which they rely on secondand third-degree price discrimination and in how likely they are to sell out concerts. Most strikingly, artists who use multiple seating categories are more likely to vary prices across markets and less likely to sell out concerts. These patterns are difficult to explain...

The impact of a challenge with moderately pathogenic <em>Escherichia coli</em> O128:C6 on the digestive physiology and gut bacterial community growing rabbits under two feeding programmes was analysed. Upon weaning (28 d old), 180 were allocated to four groups (9 cages 5 per group) for weeks: group C100 non-inoculated fed <em>ad libitum</em>; C70 feed intake limited 70% ...

This paper characterizes the optimal contract offered by an uninformed principal to an informed agent when the latter's reservation utility depends on his type. The informational rent is nonmonotonic so that interior types may have a vanishing rent or be excluded from trade. The paper identifies conditions for the optimal contract to be separating, to be nonstochastic, and to induce full partic...

An upstream manufacturer can use minimum resale price maintenance (RPM) to exclude potential competitors. RPM lets the incumbent manufacturer transfer profits to retailers. If entry is accommodated by retailers, upstream competition leads to fierce downstream competition and the breakdown of RPM. Thus, via RPM, retailers internalize the effect of accommodating entry on the incumbent’s profits. ...

We model the optimal behaviour of a multiproduct monopolist investing both in process and in product innovation in a dynamic setting. Product innovation reduces the degree of substitutability between any two varieties. First, we find that R&D efforts increase in both directions as the number of varieties grows. Second, we characterise the relative intensity of R&D activities according to the re...

The increasing hazard rate (IHR) property of distributions of asymmetric information parameters play a critical role in characterizing a separating Perfect Bayesian–Nash Equilibria in screening problems. This paper studies sufficient conditions on these distributions for IHR to be preserved under convolution. When different sources of asymmetric information aggregate into a single scalar, these...

To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...
