:One view of practical reasoning is that it involves the weighing of reasons. It is not clear, however, how the weights of reasons combine, especially given the logical and substantive relations among different reasons. Nor is it clear how the weighing of reasons relates to decision theoretic maximization of expected value. This paper constructs a formal model of reasons and their weight in order to shed light on these issues. The model informs philosophical debates about reasons, such as the question (...) of whether reasons or values are more fundamental and the opposing doctrines of atomism and holism about reasons.

This paper explores ethical issues raised by quadratic voting. We compare quadratic voting to majority voting from two ethical perspectives: the perspective of utilitarianism and that of democratic theory. From a utilitarian standpoint, the comparison is ambiguous: if voter preferences are independent of wealth, then quadratic voting out- performs majority voting, but if voter preferences are polarized by wealth, then majority voting may be superior. From the standpoint of democratic theory, we argue that assess- ments in terms of efficiency are (...) too narrow. Voting institutions and political institutions more generally face a legitimacy requirement. We argue that in the presence of inequalities of wealth, any vote buying mechanism, including quadratic voting, will have a difficult time meeting this requirement. (shrink)
