IB Economics SL Internal Assessment Example

Consider redrawing the diagram so the inflation-rate change is shown more directly, perhaps by labelling the vertical axis with inflation rather than the price level as the main focus. That would better match the concept of disinflation and reduce confusion in the diagram’s interpretation.

The explanation of the first diagram becomes inaccurate here because the move from lower inflation to a lower price level is not the same as disinflation. The student needs to show that inflation is slowing, not that the general price level is falling outright, otherwise the diagram and explanation do not match the economic concept.

The student includes a relevant AD–AS diagram, which is exactly the right type of visual support for a commentary on inflation and monetary policy. Using the model helps them organise the causes and consequences of the policy change more clearly.

The diagram is relevant, but the accuracy is weakened by the way disinflation is represented. Since disinflation means a slower rise in the price level, not a fall in the price level itself, the diagram should show a lower inflation rate rather than a lower $PL$ as the main effect.

The student also includes a Phillips curve diagram, which is relevant because it lets them link inflation changes to unemployment. This gives the commentary more analytical depth by showing both demand-side and short-run trade-off effects.

This is a useful link between the two diagrams, but it is too compressed to count as full explanation. The student should state more explicitly why the movement along the Phillips curve occurs and what happens to inflation and unemployment at each stage.

Which exact mechanism links the AD slowdown to movement on the Phillips curve in the student's explanation? Asking this will help them decide whether they need to describe lower inflation, higher unemployment, or both more explicitly.

This diagram is relevant, but the plotted movements are not fully clear enough to support the argument confidently. Make the point labels and direction of movement unambiguous so the reader can see exactly how inflation and unemployment change between the equilibrium points.

The student defines disinflation correctly at the outset, which is important because it gives the reader a clear baseline for the rest of the commentary. Using the term accurately here shows strong command of the core macroeconomic vocabulary.

The terminology becomes less precise here because the student presents the causes as though they directly explain the inflation fall without distinguishing between reduced demand, lower inflationary pressure and a possible output gap. They should be more explicit about the chain of reasoning so the economic terms are used with greater accuracy.

This is appropriate use of economic terminology because the student names the mechanism and the curve movement precisely. Linking consumption to aggregate demand and then to a specific shift helps their explanation stay economically grounded.

The student uses the transmission mechanism well here. Referring to borrowing costs and incentives to save shows accurate terminology and helps explain why expansionary monetary policy can affect aggregate demand.

The wording here is imprecise. 'Raises the surge' is not standard economic language, and the sentence implies that lower rates automatically restore the original price level. It would be stronger to state that lower rates may increase aggregate demand and put upward pressure on the inflation rate, not necessarily reverse disinflation completely.

The student could distinguish nominal and real returns more carefully. If they specify whether the loss comes from lower nominal interest earnings or from inflation eroding purchasing power, their terminology would become more precise and their evaluation stronger.

The student should not describe the ECB as 'the government' here. Monetary policy is conducted by the central bank, not the government, so this wording weakens accuracy and could confuse institutional roles. They should use 'the ECB' or 'the central bank' instead.

The student moves beyond description by linking lower inflation to purchasing power and then to real output and growth. That two-sided treatment shows good application of theory to the article’s policy context and to the well-being issue.

This application is too compressed to be fully convincing. The student names plausible causes, but they do not clearly explain whether they are reducing inflation through lower aggregate demand, easing cost pressures, or both. Developing that causal chain would make the theory fit the article more tightly.

The student applies aggregate-demand theory directly to the article by linking weaker confidence to reduced consumption and then to a leftward AD shift. This is the kind of article-specific application that makes the commentary clearly economic rather than descriptive.

This applies the monetary-policy transmission mechanism well. By connecting rate cuts to borrowing, saving and consumption, the student shows how the ECB’s decision could affect aggregate demand in the eurozone.

This overstates the likely effect of a quarter-point rate cut. The argument would be stronger if the student considered that transmission may be partial, delayed, or insufficient to eliminate disinflation entirely. Adding that nuance would improve the precision of their application.

What evidence from the article helps the student judge how large these employment and income gains are likely to be? Bringing in the scale of the inflation change and the policy timing would help them decide whether their conclusion is proportionate.

This is a strong application of theory because the student extends the analysis into the long run through investment and productivity. It shows that they are not stopping at immediate demand effects, but thinking about how policy can influence productive capacity as well.

The student applies the idea of confidence and saving behaviour well here. This is a useful reminder that policy transmission is not automatic, and it makes their application more realistic by showing why rate cuts may have limited effects.

This is a plausible extension, but it is asserted more than analysed. The student mentions a possible risk, yet they do not show the mechanism in enough detail or tie it to specific eurozone conditions from the article. A fuller chain of reasoning would make the application more developed.

Consider tightening the wording here so the well-being mechanism is more precise. Rising purchasing power is good for living standards, but falling demand does not 'lift' purchasing power; it can raise real incomes only if prices rise more slowly than wages. Clarifying that distinction would strengthen the concept analysis.

The student identifies the key concept clearly and immediately connects it to the task. Framing the commentary around economic well-being gives their analysis a clear lens, and it helps them keep linking macroeconomic changes back to living standards rather than drifting into description.

This is a strong concept-to-article connection because the student translates theory into the language of the key concept. They explain well-being through employment, income and access to goods and services, which makes the concept analytical rather than just a label.

How might the student's judgment change if the short-run employment gains were large enough to offset these distributional losses? Testing the size of each effect would make their final evaluation of economic well-being more convincing.

The student extends the concept beyond immediate price changes by considering confidence, spending behaviour and the uneven distribution of gains. This broadens the well-being discussion and shows that they are thinking about who actually benefits from policy transmission.

The student's concluding link is effective because it ties the concept to a policy judgment. They do not treat economic well-being as automatically improved by lower rates; instead, they recognise that labour-market conditions matter for whether the gains are durable.

This is a strong evaluative move because the student qualifies their argument instead of presenting the policy as universally beneficial. Recognising that effects differ across stakeholders shows balanced judgment.

This evaluative claim would be stronger with a more careful distinction between lower returns and actual negative real rates. As written, it risks overstating the harm unless the student shows that inflation exceeds the nominal return received by these groups.

The student makes a clear overall judgment rather than simply describing the policy. The conclusion is balanced because it identifies likely short-run benefits while still leaving room for limitations, which is exactly what evaluation should do.

The student supports their judgment with a realistic counterargument. Explaining why consumption may not respond strongly to lower rates makes the evaluation more credible and less one-sided.

The student's judgment is sensible, but it would be even stronger if they ranked these limitations by importance. For example, explaining which factor is most likely to constrain ECB rate cuts in the eurozone would make the evaluation more decisive and less general.

This is effective final evaluation because the student compares short-run monetary gains with the need for longer-run support. The suggestion that fiscal policy may be needed shows strong judgment about policy limitations.

If fiscal policy is needed for the long run, why does that matter for the student's final judgment on the ECB policy alone? Thinking about the division between short-run monetary policy and longer-run structural support would sharpen the evaluation.
