Will the Internet promote competition or cartelization/Price-leadership? The extra flow of information through the Internet is likely to work to the benefit of buyers, pushing prices down. But in Web-based exchanges where there are only a few seller and many buyers, the availability of more timely price information may serve to promote cartelization/price leadership, thereby increasing prices to consumers. What are the examples that producers take advantage of the Internet to implicitly fix the prices? Any way to eliminate or mitigate this problem?
