How to answer this 25 marker

* Many firms seek to maximise growth.
Evaluate whether the main influence on the size of a firm over time is economies of scale. (25)

Its my first time trying to attempt a 25 marker however I don't know what to write about or structure it.(its a bit of a mess)

Definitions relating to the point (economies of scale and/or growth)
Point - motivate the topic
Diagram - relating to the definition and point
Describe the diagram and any shifts
Consequences of the point
Evaluate - Worth 25% of the marks in 25 Markers so should be about a quarter of your paragraph
& Repeat

That's a tough question, IMO. You could potentially throw in almost anything on the syallbus? And it's always harder to do evaluation when you've got no source material to draw on?

As an A* (predicted) A-Level Economics student, whose average score on 25 markers is 21/25 I would recommend first determining what your PERSONAL opinion actually is. For the sake of example, let me say that I believe that economies of scale are not the main factors influencing the size of firms. I believe that these factors are: the availability of labor and the nature of business. Then adhere to the following structure:


2. KAA 1 (Knowledge, Application, Analysis) - This will be your first body paragraph dedicated to the first main influence on the size of a firm you have selected (Availability of labour). I would recommend you abstain from writing an introduction, as it is extremely time-consuming and will most likely not give you any extra points. However, you can use your first paragraph as a sort of a mini-intro by briefly introducing/defining your key terms/concepts (e.g. define economies of scale in your case and/or briefly list other influences on the size of firms). Subsequently, you should develop a cohesive "chain-like" argument (this will be your analysis mark), mention some data, names of firms, and points from the diagram (your application mark), and define + explain some key terms/concepts (your knowledge mark). End your paragraph with a sentence that would reference the initial question (e.g. "therefore, I believe that factor X is more influential on the size of firms over time rather than economies of scale")

3. E1 (Evaluation/counterargument) - Now write a paragraph of a similar structure on the reason why the factor you have discussed in KAA1 is NOT as influential/not influential as you said previously, and why in SOME CASES economies of scale can be MORE/LESS INFLUENTIAL than the availability of labour. I would recommend you be significantly less explicit while writing your evaluation, as it is worth fewer marks than your KAAs.

4. KAA2 - same structure as KAA1, but for another factor that you believe is influential (nature of business)

5. E2 - Same as E1, but about THIS factor

6. Conclusion - briefly summarise your key points in 2-3 sentences, ending with "I believe that the main influence on the size of a firm over time are Availability of Labour and the Nature of Business rather than economies of scale". TIP: Avoid starting your conclusion with "in conclusion".

Hope that was helpful. Good luck!
