Final answer:
Improved pricing decisions is least likely a benefit of ABC systems to managers in international trade.
Step-by-step explanation:
Improved pricing decisions is least likely a benefit of ABC systems to managers in international trade. This is because ABC systems are primarily used to allocate costs more accurately and make better decisions related to product profitability and cost control. In the context of international trade, managers may have little ability to benefit from ABC systems in terms of pricing decisions, as factors such as comparative advantage, value chain, and economies of scale have a greater influence on pricing in the global market.
