| > The social costs of gambling, particularly compulsive gambling, cannot be so easily dismissed. You might have noticed that I was not dismissing the costs of gambling. I was pointing out that merely pointing to the cost does not establish that a thing should not exist or that it should be regulated. Just as pointing to the benefit does not establish the opposite. Rather, that depends on whether one regards the benefits as worth the costs, which is not something established scientifically, but is a political matter based on your preferences and ideology. > The rules and conditions of the game must be fair, even if the outcome of the game isn’t. What counts as fair depends on the standard you use. I say what is fair that which serves a social function. Insider trading serves a social function because it more efficiently communicates knowledge about production to others. The arbitrage of insider trading which people abhor motivates insiders to eliminate those information asymmetries by engaging in insider trading. The specific profit that insider trading endows to insiders which people lambast as unfair is, in fact, the source of its fairness, because it communicates knowledge previously unknown to the market. Communication of knowledge is also a productive activity. Laws which restrict it are unfair because they preserve or limit the means by which information asymmetries are eliminated. Laws against insider trading force information asymmetries to remain, causing a permanent rent to exist. The insiders, rather than reaping a temporary profit that communicates information, now are motivated to benefit from their information in ways that do not share it with society at large; their insider information becomes an economic rent, but one without any social function. This is quite unfair. The social function of prediction markets is similar to that of insider trading. If you want to perpetuate unfair rentseeking, then please go ahead and regulate it. |
