A market in motion is what BU224 regularly hands over in Unit 2, graded on whether the analysis can tell a curve that moved from a point that slid along one. Here a composite region's used pickup market is squeezed from both sides by a new-truck shortage, and the paper shows why the price rise was certain while the quantity change was not.

What this page holds

Used pickups in a composite region, pressed from both sides by a new-truck shortage, are the market this BU224 Unit 2 supply and demand analysis works through, shift by shift. Searches like "bu 224 unit 2 assignment example", "bu224 unit 2 sample" and "bu224 unit 2 example" land here.

What a finished BU224 Unit 2 supply and demand analysis looks like

About two and a half pages with two diagrams, each followed by a paragraph that reads it. The scenario is stated in figures: average used-truck prices up from 28,000 to 33,500 dollars over six months, regional sales down from 4,200 to 3,900 a month. The first diagram shows demand shifting right, because buyers who cannot get a new truck turn to used ones. The second adds a leftward supply shift: owners who cannot replace their trucks stop trading them in. Both shifts raise price. Their effects on quantity pull in opposite directions, and the observed drop in sales tells the writer the supply shift was larger. A closing section identifies two movements along curves, buyers dropping out at the higher price and dealers bidding harder at auction, and explains why neither is a shift.

How a BU224 Unit 2 example is structured

Causes are separated before they are combined, because two shifts drawn on one figure at once hide which curve did what. Each diagram gets its own paragraph naming the determinant responsible, the availability of a substitute for demand and sellers' replacement options for supply, and stating the direction of the shift in words before the figure shows it. Only then are the two combined, and the combination is argued from the data: price rose, as both shifts predict, and quantity fell, which settles what the diagrams leave open. The final section exists to head off the unit's central confusion. It names the price-driven responses in this market and labels each as movement along an existing curve, with one sentence on what would have to change for it to count as a shift instead. Both figures carry labeled axes and equilibria.

A market in two numbers

Average price up from 28,000 to 33,500 dollars and monthly sales down from 4,200 to 3,900, both composite, stated before any curve is drawn.

Demand moves right

Buyers shut out of new trucks turn to used ones. The determinant is the availability of a substitute, and the figure shows the whole curve relocating.

Supply moves left

Owners who cannot replace their trucks keep them, so fewer reach dealer lots. Same root cause, opposite side of the market.

What the sales figure settles

Both shifts raise price; only their relative size decides quantity. Falling sales mark the supply shift as the larger of the two.

Slides, not shifts

Buyers leaving at the higher price and dealers bidding more at auction, each identified as movement along a curve already in place.

Where marks go in BU224 Unit 2

The costliest mistake in Unit 2 is calling a price-driven response a shift, for instance saying demand fell because prices rose, which reverses the logic of every step after it. Analyses that combine two shifts on one diagram without separating them often reach the right price conclusion by accident and cannot defend the quantity result. Many sections deduct for naming a shift with no determinant, as if curves moved on their own. Claiming a definite quantity change when two shifts point opposite ways is marked as overreach unless data resolve it. Figures drawn and never read in the text lose most of their value. A determinant assigned to the wrong side, such as treating sellers' expectations as a demand factor, costs accuracy points, and ignoring price or quantity data the prompt supplied costs more.

BU224 Unit 2 questions, answered

How do I know whether something shifts demand or supply?

Ask whose behavior changes first. If buyers want more or less at every price because of income, tastes, related goods or expectations, demand shifts. If sellers can offer more or less at every price because of costs, technology or the number of sellers, supply shifts. A change in the good's own price shifts neither; it moves along both.

What if both curves shift and the prompt gives no data?

Then say which outcome is certain and which is not. When demand rises and supply falls, price rises for sure while quantity depends on the relative sizes. Stating that plainly, and naming what evidence would settle it, earns more than guessing a direction and defending it as though the diagram proved it.

Does the analysis need real market data?

Not usually. Most Unit 2 prompts supply a scenario, sometimes with figures, and the analysis works within it. Where you choose your own market, a published price series such as an industry index of used vehicle prices can anchor it, cited with its period. Invented figures should be labeled as illustrative so the grader reads them that way.
