We study collusive pricing in duopoly with uncertain demand and exogenous capacity constraints. In this setting, collusion using only symmetric pricing can limit collusive pro…ts. We …nd that using asymmetric pricing in some demand states permits higher sustainable collusive pro…ts over the entire range of demand states. Consequently, we show joint pro…t maximizing collusion can include both sy...

In recent years asymmetric cross section aluminum alloy stock has been finding increasing use in various industrial manufacturing areas such as general structures and automotive components. In these areas, components are generally required to have complex curved configuration and, as such, a bending process is required during manufacture. Undesirable deformation in bending processes such as fla...

Asymmetric-circular shaped slotted microstrip patch antennas with slits are proposed for circularly polarized(CP) radiation and radio frequency identification reader applications. A single-feed configuration based asymmetric-circular shaped slotted square microstrip patches are adopted to realize the compact circularly polarized microstrip antenna. The CP radiation can be achieved by slightly a...

this study took an epidemiological approach toward the problem of drug addiction in tehran. the subjects were 300 addicts chosen on the basis of stratified random selection out of the population of 3627 prisoners who were all proven addicts and sentenced to imprisonment by the court in the year 1370. a descriptive survey showed that drug addiction generally, and heroin addiction specifically, i...

We focus on the application of path dependence logic in organizations, particularly on the role of self reinforcing mechanisms in the evolution of institutions in business firms. Path dependence theory suggests that self reinforcing mechanisms may lead to very high persistence of inefficient institutional solutions. The so called lock-in can create a growing threat to an organization’s viabilit...
