Lecture Material

We covered...

Each potential outcome has a benefit and a cost ( Utility = Benefits - costs ) If the costs of an action outweigh the benefits of that same action, a person will not do that thing. -So, with voting...if the costs of voting outweigh the benefits of voting, it is irrational to vote

Anthony Downs' An Economic Theory of Democracy -Rational action: to proceed in such a way to use up the lease scarce resources possible per unit of desired output to the best knowledge of the individual (minimizing use of scarce resources, maximizing benefits) -If costs outweigh benefits, the choice is irrational -Restricts rational choice theory to economic and political motivations -"D term" is the civic duty to vote (reduces costs of voting, does not impact how people vote, rather if they vote at all) -So now.... Utility = Benefits - costs + D

Standards of Rationality:

-Able to make a decision if presented with options -Rank order of preferences -Transitive preferences -Choose most preferred option -Same decisions made time and time again

Rational choice theory-issues with disproving it -one can change the inputs to get the right explanation

Solutions:

-No cost of voting -Cost of voting prohibitive -Save democracy (long-term cost) -Selective benefits ("good" feeling from voting, civic duty, solidarity, expression of opinion)
