Problem: Conventional wisdom in political science suggests PR electoral systems create redistributive tax-and-transfer policies favoring the poor. But empirical observation shows many PR countries rely on regressive consumption taxes and lightly tax profits.

New Insight: Countries with PR systems combined with trichotomous multipartism don't universally target redistribution downward; outcomes depend heavily on multinational labor market structures.

Data & Methods: Theoretical model evaluating implications for a world dominated by multinationals.

Focus is placed on understanding the interaction between electoral institutions and labor markets rather than direct empirical measurement.
