Economics are about the behaviour of people, so about matters that you can see in your own environment. In the subject of economics a household is every unit which independently makes economic decisions. Such economic decisions often involve making choices. You can choose what kind of work you want to do, how long you want to work, what you do with your leisure time, what you buy with your money or how much money you want to save every month. This lesson deals with a number of different concepts that are related to that. Among other things you will learn how to calculate with percentages, how to budget and how you can save and borrow. And what is the difference between having an enterprise of your own and working for a boss?
