Economists call this \"imperfect\" because we rarely have all the data we need to make perfect decisions. Despite the lack of perfect information, we still make hundreds of decisions a day. Now we have another avenue in which to gather inforrnationsocial media. Outlets like Facebook and Twitter are altering the process by which we make choices, how we spend our time, which movies we see, which products we buy, and more. How many of you chose a university without checking out its Facebook page or Twitter stream first for information and feedback? As you will see in this course, what happens in economics is affected by how well and how fast information disseminates through a society, such as how quickly information travels through Facebook. \"Economists love nothing better than when deep and liquid markets operate under conditions of perfect information,\" says Jessica Irvine, National Economics Editor for News Corp Australia. i.
