Tying

What is tying and how is this a form of price discrimination? An example of a tied good is an HP printer and the HP ink you need for that printer. The printer (the base good) is often relatively cheap whereas the ink (the variable good) has a high markup, and eventually costs you far more than what you paid for the printer. Other examples include cell phones and data plans or the Kindle Fire and the accompanying books or music you purchase from Amazon. The base good is sold close to marginal cost, and the variable good is sold at above marginal cost. Why do companies tie their goods? Tied goods make it easy to price discriminate in a way that increases output and social welfare. Does tying increase or decrease social welfare? What is the difference between bundling and tying? We discuss these questions and others in this video. Microeconomics Course: http://bit.ly/20VablY Next video: http://bit.ly/1oHyng9 Help us caption & translate this video! http://amara.org/v/GZRa/
