It seems to me that a lot of the angst about the Comcast-Netflix paid transit deal results from a general discomfort with two-sided markets rather than any specific harm caused by the deal. But is there any reason to be suspicious of two-sided markets per se?
Consider a (straight) singles bar. Men and women come to the singles bar to meet each other. On some nights, it’s ladies’ night, and women get in free and get a free drink. On other nights, it’s not ladies’ night, and both men and women have to pay to get in and buy drinks.
There is no a priori reason to believe that ladies’ night is more just or efficient than other nights. The owner of the bar will benefit if the bar is a good place for social congress, and she will price accordingly. If men in the area are particularly shy, she may have to institute a “mens’ night” to get them to come out. If women start demanding too many free drinks, she may have to put an end to ladies’ night (even if some men benefit from the presence of tipsy women, they may not be as willing as the women to pay the full cost of all of the drinks). Whether a market should be two-sided or one-sided is an empirical question, and the answer can change over time depending on circumstances.
Some commentators seem to be arguing that two-sided markets are fine as long as the market is competitive. Well, OK, suppose the singles bar is the only singles bar in a 100-mile radius? How does that change the analysis above? Not at all, I say.
Analysis of two-sided markets can get very complex, but we shouldn’t let that complexity turn into reflexive opposition.
