Which source would be most useful for a student writing a paper that argues that Americans should be fined if they do not vote?

A scholarly article or research paper that analyzes the effects of compulsory voting in other democracies would be most useful for a student writing this paper. It could provide empirical data and case studies supporting the argument that fines increase voter turnout and enhance civic engagement. Additionally, legal analyses discussing the implications and constitutionality of imposing fines for non-voting could strengthen the argument. Such sources would provide credible evidence and a broader context for the proposal.
