The fifth edition of Mastering Economics has been completely revised and updated. It takes the student through the strengths and weaknesses of the market economy, the role of the government in the economy and the UK's relationship with the European Union especially with regard to adopting the single currency. Care has been taken in selecting and explaining such economic theory considered essential to policy decisions. Each chapter is introduced with a summary of objectives and ends with self-test questions with answers given at the end of the book.
