Gary W. Cox. Making Votes Count. Cambridge: Cambridge University Press, 1997. Chapters 1-3, 4 (pp. 69-80), 8, 10, 12-15.
The book focuses on district, post-entry politics. The post-entry period allows Cox to observe an actual number of entering candidates reduce to a smaller effective number of vote-getting candidates. (In contrast, pre-entry politics involves observing an indefinitely large number of potential candidates reduce to a definite field of actual candidates.)
The independent variables examined in the nature of electoral coordination problems:
- Electoral institutions - these determine how votes translate into seats and the available opportunities for trading votes in order to win more seats
- Political motivations / political actors' preferences
- Public expectations / actors' expectations
Review of perspectives about electoral systems:
- Institutionalist perspective - party system deterimines the number of parties.
- Duverger: the simple-majority single-ballot system favors the two-party system; the simple-majority system with second and ballot proportional representation favors multipartyism.
- Sociological perspective - social and ideological cleavages explain party system and the number of parties; the greater the social fragmentation, the more probable is the adoption of a proportional electoral system and the rise of a multiparty system.
- Ordeshook and Shvetsova (1994) - the number of parties in a country increases with the diversity of the social structure and with the proportionality of the electoral structure and these effects interact.
- Leys and Sartori conjecture - There is a continuum of systems, ranging from those in which strategic voting imposes a constraining upper bound, to those in which it imposes a rarely-constraining or unconstraining upper bound, on the number of parties.
- Electoral system - set of laws and party rules that regulate electoral competition between and within parties.
- Electoral formula - method for translating candidate and/or list vote totals into an allocation of seats among cartels, lists, or candidates.
- Structure of an electoral system = subsystem within the electoral system
- District structure has to do with the number, magnitude/size, and nature of electoral districts. District magnitude is the number of representatives it is entitled to elect.
- Primary electoral district - district that cannot be partitioned into smaller districts within which votes are aggregated and seats allocated.
- Secondary electoral district (upper tier) - distrct that can be partitioned into two or more primary electoral districts.
- Alliance structure has to do with opportunities to pool votes and refers only to the potential relationships that may obtain between candidates and lists, not to any actual pattern of use of the legal options.
- Formulaic structure / subsystem has to do with the multiplicity of different electoral formulas that can appear at different levels in a system
- Exclusive candidate vote / single nontransferable vote benefits only the candidate for whom it is cast and never transfers any other vote total that is used for purposes of seat allocation.
- Nonexclusive candidate vote / single transferable vote appears in the vote total of the candidate for whom it is cast and affects vote totals used in the allocation of legislative seats.
- Fused vote casts a single vote for a slate that includes a candidate for the presidency as well as candidates for the legislature.
- In casting multiple candidate votes, the allowance of plumping allows voters to not use all of their votes, panachage means voters need not vote only for candidates of one party, cumulation means voters can give more than one of their votes to a single candidate.
- Dual-ballot single-member systems allow voting for candidates in rounds.
- the presence of voters who are not short-term instrumentally rational
- lack of public information about voter preferences
- public belief that a particular candidate will win with certainty
- the presence of many voters who care intensely about their first choice and are nearly indifferent between their second and lower choices
When coordination succeeds, the most readily observable consequence is a reduction in the number of electoral players: the number of lists or candidates appearing on the ballot is decreased when elites agree to a merger of parties, or a joint list, or a fusion candidacy; the effecive number of lists or candidates is decrased when voters strategically concentrate their votes on the more viable lists and candidates. When electoral coordination fails, the maladroit find themselves underrepresented while the better-coordinated find their representation magnified.
