If I want to know what the weather forecast will be, I can justtype into Google: " Fort Lee, Va. Weather" and the basicinformation pops right up. If I want more detail I can click any ofthe first few links and with pretty little effort I'm able to viewthe current and forecasted radar maps. I'm able to do all of thiswithout any monetary payment and without logging into any accounts.Is this an example of a market transaction? What must be true ofthe cost structure here in order for this pricing to make sense?Explain!
