IB Economics - Glossary of terms This resource is designed to help you make accurate use of specialist economics terms in your work. It is up to you how much use you make of it. Some of you will benefit from it hugely; others will find it more use as a revision tool rather than one that will help them use terminology more accurately. If I find that you are not making sense or that you are using words inaccurately then I may insist that you start to complete this and use it. It is useful for both native and non-native speaker alike. In economics many words have a specific meaning that is not the same as the one they have in every day English.The booklet is laid out in the same order as the course:Introduction: The Foundations of EconomicsMicroeconomicsMacroeconomicsInternational TradeDevelopment EconomicsThe words are in English. If English is not your ‘home language’, you need to write them in your ‘home language’.It is up to you to ensure that you are using the right word here. Remember words often have different meanings.Then you must write in your own definition. Avoid using ‘cut and paste’ or use definitions you happen to find on the Internet! The very act of writing the definition and thinking about what you are writing will go a large way to helping you remember it. Again, take care that you are using the word in the right way. For example, when we talk about a complement do we mean “Your hair looks nice” or “Two goods in joint demand”? Don’t complete it all in one go, but do it steadily as we go through each unit.
