Duverger's law
In political science, Duverger's law holds that single-ballot plurality-rule elections (such as first past the post) structured within single-member districts tend to favor a two-party system. [T]he simple-majority single-ballot system favours the two-party system. The discovery of this tendency is attributed to Maurice Duverger, a French sociologist who observed the effect and recorded it in several papers published in the 1950s and 1960s. In the course of further research, other political scientists began calling the effect a "law" or principle. As a corollary to the law, Duverger also asserted that proportional representation favors multi-partism, as does the plurality system with runoff elections. [B]oth the simple-majority system with second ballot and proportional representation favour multi-partism. Duverger's law draws from a model of causality from the electoral system to a party system. A proportional representation (PR) system creates electoral conditions that foster the development of many parties, whereas a plurality system marginalizes smaller political parties, generally resulting in a two-party system. Most countries with plurality voting have representation in their legislatures by more than two parties. While the United States is very much a two-party system, the United Kingdom, Canada and India have consistently had multiparty parliaments. However, only the two dominant parties of their times have formed governments in the United Kingdom and Canada. Eric Dickson and Ken Scheve argue that there is a counter force to Duverger's law, that on the national level a plurality system encourages two parties, but in the individual constituencies supermajorities will lead to the vote fracturing. Steven R. Reed has shown Duverger's law to work in Japan and Italy.In recent years the validity of this law has come under increasing quantitative scrutiny.
