Economics for AS matches the requirements of the new OCR economics specifications. In one volume, this definitive text provides all the information students need for the AS (advanced subsidiary) units 'The market system', 'Market failure and government intervention', and 'The national and international economy'. The book also includes the compulsory A2 unit 'Economics in a European context', a synoptic assessment unit for the second half of the A level course. To help students understand the topics and prepare for examinations, the authors have included a wide range of stimulus material, as well as self-assessment exercises drawn from OCR material. The book is written by the chief and principal examiners and endorsed by OCR. It is also relevant to students studying AS economics for AQA and Edexcel, and is an excellent foundation text for undergraduates.
