Ethnic Identity, Voter Choices and Informal Institutions in Solomon Islands

This paper reports the findings of a mixed methods study of electoral politics in Solomon Islands. In particular, it looks at Solomon Islands voters' propensity to vote for co-ethnic candidates in national elections. The paper provides a typology of existing theories of ethnic voting before drawing on quantitative evidence to show existing theories do not fit the Solomon Islands case, despite ethnic voting being well described there. The paper then draws on qualitative evidence to create a new theory in which ethnic voting is argued to occur in Solomon Islands because informal institutions associated with ethnic groups help overcome collective action problems central to clientelist electoral politics. In the papers final section the theory is tested using multiple regression analysis.
