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:
Now you’re ready. Here’s the Method:
Don’t waste words with a lengthy introduction (or quotations). Instead right away start explaining the case using at least 4 course words (and then use more later). You may want to define some of these words, but we’re definitely not looking for a list of definitions. Actually definitions are not specifically required in this new syllabus.
The rubric only asks for terms to be "used appropriately." So you can get away without definitions if you are using terms in ways that show you definitely know what they mean. If you do define some words (which is still advisable) , do so only after you've used them in a sentence. Also, make sure to always use the economic terms rather than the common terms for things throughout your IA. So instead of writing “money” write “consumption” or “expenditure” or “spending.” This will help to convince the reader you are familiar with the subject.
The diagram (and it's titles, etc) do not count in your word count. You need to diagram the problem explained in the article. And also diagram your solution. Sometimes both the problem and the solution can be shown on one diagram. Sometimes not. Of course don’t include a diagram (or any theory at all) that doesn’t help you to explain the case. Include in your diagram as much information as you can. It will need to:
-Use a full title such as, “The Market for Apples in Singapore”
-Label all of your lines
-Mark all of your intersections with a letter, so you can refer to them later in your article
-Shade in and fully label the areas of the shapes on your diagram (i.e. excess demand),
-Indicate the exact prices and quantities (or percentage changes in price or quantity if they are included in the article. If not, label them Q1, Q2, P1, P2, etc.
Show as much as you can in your diagrams. A clear picture can help you tell a lot.
Obviously you will want to fully label your X and Y axis. Let’s look at a simple supply and demand curve for apples:
A big mistake students make is that they will identify the key concepts that explain the case, but they don’t explain how those concepts work. They skip steps in their explanation. It’s human nature to do that. We all do that all the time. We assume the reader is understanding what we’re saying. In this case you can’t do that. You need to force yourself to explain things step by step. Let’s look at an example. I have a students’ (practice) commentary in front of me that reads:
“Supply shifts inward because there was a draught. This leads to a higher price and a lower quantity demanded”
Maybe you’re thinking this isn’t too bad. However, this student has skipped a few steps. He doesn’t make it understandable to a reader who doesn’t know the theory. If you have to be an expert to understand what you’re talking about you aren’t doing it right. You can’t think of your reader as an expert. My student here could have written something like:
“The leftward shift of the supply curve means that, for any given price, less is supplied. This creates excess demand at the original equilibrium price, which puts upward pressure on price. Producers receive the signal to increase their prices and they do.”
Writing like this (step-by-step) isn’t easy. Luckily in this case you get to edit your own writing as many times as you want before you hand it in.
Analysis is about explaining how the theory relates to the case. You have already done a lot of that by FULLY explaining your diagram. But now I want you to take it a step further. Go deeper in your explanation. For example, explain how what is happening in the article is not exactly what the theory said would happen (i.e because of the external factors that exist).
Explain to us to what extent the theory you have used explain what’s actually going on in the article? And show the linkages between different aspects of theory. Basically you're trying to take it to the next level. But you aren't evaluating. You're just making sure that you have fully explained the theory and how the theory relates to the case.
Every article is about a problem. For example, apples are too expensive after the drought. In your commentary you’re expected to evaluate ONE possible solution. If one is mentioned in the case it must be that one that you evaluate. You can suggest one and evaluate that only if a solution isn't already mentioned in the article. You want to choose the most appropriate (most likely) solution here, rather than one that is obviously not going to work at all.
To evaluate you'll need to use at least 3 different (CLASPP) approaches. (The CLASPP approach to Economics evaluation is explained here). Try to include "assumptions" of the theory if you can, to show the limits of the theory and that it doesn't always work out in real life. In the final of the 3 posts on Mastering the Economics IA we will take a detailed look at the 2013 rubric and use a checklist to make sure you really do get full marks. -- Thanks to my fellow HL Econ teachers Niamh Bowman (at OFS) for her feedback on this method.
