Our analysis extends previous results on optimal committee decision-making to a sequential setting, and further demonstrates the fragility of the hierarchy and polyarchy as optimal architectures.

Further statistical analyses on the market dynamics of price trends show that the prices of the Dotcoms went up with time much faster than the prices of the MCRs, which points to a possibility that eventually both types of retailers may charge similar prices on average. …
