The difference between macro and micro economics is one that many students don't understand. However, it doesn't have to be confusing if you learn to differentiate between the two. When you study microeconomics, you study the small world of individual economic actors, their interaction with one another and the market. Macroeconomics studies the larger world, including global economies and international trade and finance.
Microeconomics is all about examining how things are done at the individual level and considering how they affect the wider macroeconomic environment. This is why it is best studied in a way that focuses on the micro as opposed to macro – that is, studying microeconomics in a way that doesn't look at macro as it has long been practiced.
In macroeconomics, you study all the big picture, and it doesn't matter how you get there. For instance, when you learn macroeconomics, you learn how different policies can affect the macroeconomic environment. If a policy is implemented, the economy will experience either positive or negative effects. In some cases, you will be able to observe an effect on the GDP and unemployment rate – this is a micro effect. And when the recession hits, you can also observe an impact on the GDP and unemployment rate, even if that impact isn't so good.
But macroeconomics is also about how a policy affects the whole economy, in order to arrive at a conclusion. In macroeconomics, you can use data from several different countries to see what happens to the economy when a certain policy is implemented in those countries. You will get different results depending on where the policy was implemented, what type of policy it was, and what types of countries were affected. There are so many variables that go into macroeconomics that you won't be able to take everything into account in your first couple of years of study.
By studying microeconomics, you are better equipped to tackle macroeconomics. This means that you'll be better able to look at what factors cause changes in the economy – for example, how a certain increase in the price of oil will change the price of gasoline in an oil-exporting country – and then use that information to make decisions about the future of an economy based on the data. You can't just look at the data and use the data to make an informed guess about a situation – you need to actually look at it and determine whether or not the data is correct.
You can learn about the two main types of macroeconomic models by looking at both macro and micro data. However, it is much easier to master macroeconomics by studying micro, since you'll be more familiar with the underlying theories. and the terminology, which is used in macroeconomics.
