The book follows the structure of the IGCSE and -C s O Level course closely. es y The Coursebook is divided into 39 chapters. Each of these chapters explores a key economic Pr op topic and is based on a section of the syllabus. Each one has activities, multiple choice ity C questions and four-part questions to assess your understanding of the topic. In the first six rs w chapters, the four-part questions actually contain fewer than four parts. This is because ie ve economics is a subject where concepts build on each other. As more concepts are covered and y ev depth is built up, the four-part questions in the remaining chapters do have the full four parts. op ni R U Each chapter contains one or more tips. This may remind you of a key point, warn you about C a common confusion, give you advice on how to approach a question or recommend an ge w activity which will enhance your understanding. At the end, there is a summary of the main ie id points covered in the chapter. Throughout the book, there are links to parts of other chapters ev br where concepts can help you understand the topic. am -R The chapters have been arranged into six sections. At the end of each section, there are -C ten multiple choice questions, data questions and four-part questions covering the whole s es section. y Pr op iv Introduction to Economics ity C Economics is an important, well-respected and exciting subject. Economists play a key role rs w in the world. They give advice to firms and governments to improve their performance and ie ve y also comment on their success or failure. The work of economists can make a significant ev op ni difference to people’s lives. For instance, the policies they recommend to governments may R U C reduce poverty and improve the quality of the environment. ge w Whilst some of the people who study economics go on to become economists, others enter ie id a range of professions including accountancy, banking, education, journalism and the law. ev br Economists enjoy a lot of respect in universities and professional organisations. They regard am it as a rigorous subject that develops logical thinking and analytical and mathematical ability. -R There are certain concepts – such as opportunity cost and price elasticity of demand – -C s and certain topics – including price determination, unemployment and inflation – that are es central to economics. The subject, however, is ever changing as new theories develop, new y Pr op institutions are created and new problems are encountered. This makes it an interesting and challenging subject. ity C rs w The skills of an economist ie ve y ev op ni To be a good economist, you need to be informed of the developments in your economy and R U other economies. You need to be able to think and write clearly and apply relevant economic C terms and concepts. You need to be confident in handling figures. This involves being able e w g to add, divide, subtract, multiply, calculate percentage changes and understand index ie id ev br am -R -C s es Copyright Material - Review Only - Not for Redistribution  ity rs Introduction ve y op ni U C numbers. You also need to be able to draw relevant, well-labelled and accurate diagrams. ge w This Coursebook is designed to help you develop these skills. ie id ev br Preparing for your examination am -R Revision is a continuous process. After every lesson, check your work and if necessary, add -C extra notes. As an examination approaches, you will need to do intensive revision. Try to s es engage in active revision. This involves, not just reading notes, but also using the information. y There are a number of ways in which you can do this. They include testing other members of Pr op your group, and getting them to test you, drawing spider diagrams and producing tables and ity C revision cards. rs w ie ve Examination technique y ev op ni It is not sufficient to have a sound knowledge and good skills in the subject. You also have to R U C demonstrate these under examination conditions. So, it is essential to develop examination ge techniques. w ie id Before an examination, check out the duration of the examination and the number of ev br questions you have to answer. Read the instructions on the examination paper carefully. am Do not rush into writing your answers. -R In answering multiple choice papers, consider every option in a question carefully. If you are -C s uncertain of an answer to a particular question, move on to the next one and return to the es question you were unsure of when you have answered the other questions. At the end, check y Pr op that you have answered all the questions. Never leave a question unanswered, even if you v have to guess. ity C In answering four-part questions read the questions very carefully, paying particular rs w ie attention to the command (instruction) words. A question which asks you to identify or state ve y ev something will only require a brief answer, consisting of a few words. In contrast, a question op ni which asks you to explain, analyse or discuss something will require a longer answer, written R U C in sentences and paragraphs. Unless specifically asked for, you should avoid writing a list. ge w The marks allocated to a question or part of a question should give you a clear indication ie id of the extent of detail required. It is often useful to include a diagram (or diagrams) in your ev br answers. These should be clear, accurate, well-labelled and backed up by an explanation am -R in the text. -C s Stretch content es y As well as covering all of the topics on your course, in places, the book goes beyond the Pr op syllabus to include concepts that stretch your understanding and provide you with possible ity C new ways to approach particular topics and strengthen the depth of your answers. These are marked in the book with a blue line next to them in the margin, and also listed in the table rs w below for your reference. ie ve y ev op ni R U C e w g ie id ev br am -R -C s es Copyright Material - Review Only - Not for Redistribution  ity rs Cambridge IGCSE Economics ve y op ni U C Topic Where found in Coursebook ge w Allocative, productive and dynamic Chapter 13.4 Allocative efficiency, Chapter 13.5 Productive ie id efficiency efficiency and Chapter 13.6 Dynamic efficiency ev br am Cost benefit analysis Chapter 15.3 Government measures to address market -R failure (Effectiveness of government intervention) -C Average propensity to consume Chapter 17.1 Spending (Income and consumption) s es Average propensity to save Chapter 17.2 Saving (Income and saving) y Pr op Aggregate demand and aggregate Chapter 25.1 Government’s macroeconomic aims ity C supply analysis (Economic growth) rs w Purchasing power parity Chapter 32.1 Indicators of living standards (Comparing ie ve living standards between countries) y ev Genuine Progress Indicator, Gender Chapter 32.1 Indicators of living standards op ni Inequality Index.
