Before revision:  When the underlying decision problem has a continuum of actions, optimal mechanism has a continuum of experiments . Buyers with more extreme private beliefs purchase less amount of information at lower prices. When distribution of decision maker`s type becomes more dispersed, more buyers will be included in the market and all buyer type will be sold a more informative experiment .
After revision:  When the underlying decision problem has a continuum of actions, optimal mechanism has a continuum of experiments . Buyers with more extreme private beliefs purchase less amount of information . I also find a complementarity between buyer's private information and information provision: when buyer's private signal is more informative, the optimal menu contains more informative experiments .
