Twelve suppliers on paper, three that can actually deliver: this BU224 Unit 7 market structure case classifies a composite county's ready-mix concrete market as an oligopoly from its conditions.

What a finished BU224 Unit 7 market structure case looks like
A case analysis of about three pages with a conditions table at its center. The composite facts lead: twelve ready-mix producers appear in the state directory, but concrete must be placed within about ninety minutes of mixing, which caps a truck's useful radius near thirty miles. Only three plants fall inside it. The table rates the local market on five conditions: effective sellers, product differentiation, entry barriers, control over price and mutual awareness. A new plant costs several million dollars and needs air and zoning permits. Bids across the three plants move together, and each firm tracks the others' quotes. The case classifies the market as oligopoly and predicts steady prices, rivalry on delivery reliability and occasional price leadership. A contrasting paragraph places the county's forty hair salons in monopolistic competition.
How a BU224 Unit 7 example is structured
Facts first, headcount second, conditions third: the case is ordered to show why the obvious number misleads before replacing it with a better test. The ninety-minute limit arrives early because it redraws the market boundary, and everything after depends on that boundary. The conditions table gives each of the five criteria one row, with evidence from the case beside the rating, so the classification is visibly built rather than announced. Oligopoly is named only after the table, and the prediction section follows directly, since the unit asks what the structure implies for pricing, not just what it is called. The salon paragraph works as a control: many sellers that still fail the perfect-competition test, which shows the method cutting both ways. One closing sentence says what would change the classification, a fourth plant opening within range.
Twelve names in a directory
The headcount the case supplies, and why a supplier on the far side of the state cannot sell a single load in this county.
Ninety minutes and thirty miles
Concrete's working time redraws the market boundary, leaving three plants that can actually compete for local jobs.
Five conditions, rated
Effective sellers, differentiation, entry barriers, price control and mutual awareness, each with evidence from the case beside its rating.
What oligopoly predicts here
Stable prices, rivalry on delivery reliability rather than price, and the largest plant setting quotes the other two tend to follow.
Forty salons as a control
Many sellers with differentiated service and easy entry, classed as monopolistic competition to show the method working in the other direction.
Where marks go in BU224 Unit 7
The largest deduction in Unit 7 goes to classification by counting, twelve firms and therefore competitive, which ignores the delivery constraint the case places in plain view. A classification stated without evidence for each condition draws the next loss, since graders in many sections want the reasoning visible row by row. Confusing monopolistic competition with oligopoly is common and costly; both involve some control over price, and the difference lies in entry and mutual awareness. Cases that name the structure and stop, with no prediction about pricing or rivalry, miss the half of the prompt asking what the structure implies. Claiming collusion from parallel pricing alone, without evidence of agreement, is marked as an unsupported inference. Treating a standardized product as differentiated because brand names exist costs accuracy points in some sections.

BU224 Unit 7 questions, answered
What if the case gives a number of firms but little else?
Then read every fact for what it implies about entry, differentiation and interdependence. Capital costs, licenses, transport limits and brand loyalty all appear in cases as passing details. Where the case is genuinely silent on a condition, say so and state the assumption you are making, instead of letting the headcount decide by default.
Is a market with three firms always an oligopoly?
Not always. Three firms that each dominate a separate local area might be closer to local monopolies, and three firms in a market anyone can enter cheaply may behave competitively. Oligopoly turns on interdependence: each firm's best move depends on what the others do. Evidence of that awareness is what confirms the classification.
Should the case discuss antitrust law?
Only if the prompt raises it. A sentence noting that parallel pricing is not by itself illegal can be useful where the case hints at it. Detailed legal analysis usually falls outside a microeconomics unit, and space spent there is space not spent on the conditions and predictions the rubric actually grades.
