This post will go through what you should write in your Economics IA, with step-by-step instructions and with word counts for each section.
What you need to know before you write:
1) Avoid writing anything that isn’t going to earn you marks. You’re going to need all the words you can get for your analysis and evaluation. Avoid quotes from the article and introductions longer than 2 sentences.
2) Stick with one section of the course (micro, macro, international, or development). Don’t start off in micro (apple prices rise, supply and demand, elasticity) and then evaluate the potential macro effects (this could hurt economic growth). Even if this is true, the IA is about going deep into one part of the course, rather than showing the linkages between different parts.
3) Less is (often) more. Because of the very constraining word count (750 words) you’ll want to focus on really developing just one or two (two at the most) diagrams in your IA. And only evaluate one potential solution (the one in the article or one of your choice if (and only if) there isn’t one in your article. Some of you, I know, are wondering, “What if the article mentions two solutions? Like price ceilings AND subsidies?” Answer: the International Bacheloreate Organization says you can highlight the section of the article you’re going to focus on, so just highlight one solution (and not the other) and you’re good to go. Bibliographies are not obligatory, but they’re nice. And if you include them, they won’t count against you for the word count.
Now you’re ready. Here’s the Method:

150 Words
Don’t waste words with a lengthy introduction (or quotations). Instead right away start explaining the case using 3 or 4 course words. And then define these words. We’re not looking for a list of definitions. Rather the definitions should come in after you have just used the word in a sentence. So, as a rule
