Expressive Voting - Public Choice Theory - Geoffrey Brennan

When you vote in an election, what are you really doing? Professor Geoffrey Brennan challenges students to question standard assumptions about what voters are doing when they vote. He argues that voters don’t actually "choose" candidates in the normal sense of that word, since a single vote almost never determines the outcome of an election. Prof. Brennan argues that each vote, by itself, is more like cheering for a sports team, and that this has important implications for the workings of democratic politics. He stresses the importance of understanding elections and other democratic processes as they actually are, not as we wish them to be, in order to work toward better policies and governance.
Prof. Brennan is Emeritus Professor of Economics at Australian National University. From 1976-1983 Geoffrey was Professor in the Public Choice Center at Virginia Tech, where he worked extensively with (1987) Nobel Laureate James Buchanan. Since 2005 he has spent a semester each year in the joint Duke/UNC PPE program as the General Director.

Great video! My question would then be: if one where to sell his vote, what would it be worth? In your case it’s basically zero, but if you ask anyone on the street they would not accept that offer.

[@MVequalsPY]

The vote's value is only approximately zero on the demand side - on the supply side the value is, by revealed preference, at minimum the voter's willingness to pay to vote: the value of the time, effort (physical and mental) that the voter "pays" to engage in the process which exceeds the negligible probability of its instrumental value. Their willingness to accept payment for their vote may exceed this, obviously. Figuring out why they are willing to undertake these costs to vote leads to the answer to your question (i.e., why they wouldn't sell their vote for a price equal to or marginally more than it's expected value in terms of instrumental electoral impact).
