Final answer:
Cross-education mechanisms relate to how education influences perceptions of trade and economic policies. The more likely mechanism is that trade policy preferences stem from an interaction between educational level and material effects, as supported by multiple studies.
Step-by-step explanation:
The student is asking about mechanisms that explain cross-education effects. Two possible mechanisms are the idea that perceptions of trade liberalization are influenced by one's educational level, as illustrated by Yale University's Kenneth F. Scheve and Dartmouth's Matthew J. Slaughter, and the concept that educational attainment and occupation levels interact with material effects to shape individual preferences toward trade policies. The latter mechanism seems more likely, as it accounts for both skill level and material effects, a conclusion supported by the replication of Scheve and Slaughter's study by Martin Ardanaz, M. Victoria Murillo, and Pablo M. Pinto in Argentina, suggesting that support for economic integration depends on educational levels and material effects alike.
