Refreshed and updated PowerPoint resources aimed at assisting teachers with the delivery of the WJEC A-level Business specification.  These slides are designed to support the delivery of the Unit Four topic of international trade.  They consider the purpose and nature of international trade, looking at specialisation, comparative advantage, free trade, trade blocs, protectionism (including quotas and tariffs), and how UK firms can seek out new international markets and the difficulties they face in doing so including cultural differences. The slides contain the Quick Fire Five questions and also a practice extended answer question (both with suggested solutions).
