This is the final exam for Creative Destruction. It pulls the whole course together: growth as replacement rather than accumulation, the two mirrored S-curves and the crossover that dooms an incumbent, the engine that powers the gale (the entrepreneur forcing new combinations, Schumpeter’s five kinds of innovation, and the temporary rent that fuels the next wave), why clear-eyed incumbents lose anyway to the incumbent’s curse and the innovator’s dilemma, the long wave of boom and bust, and — most important of all — where the model lies. Several questions look easy until you notice the destruction is genuine, the “innovation” is only rent-seeking, or the confident date is astrology with charts. Reason each one through.
How this exam works
Read carefully — this exam is final. Each question appears one at a time. Once you submit an answer it is locked for good: there is no going back, no retry, and no restart. Your score is hidden until the end, where you will see a pass/fail verdict. The pass mark is 70%. A few questions ask you to select all correct answers.

Course Recap
Big picture
Creative Destruction — the whole model
- Creative Destruction
- Destruction, not addition
- Growth is replacement, not accumulation
- Two mirrored S-curves: challenger up as incumbent falls
- Same customers, capital, workers cross over (conserved)
- 50% crossover: market decided, incumbent doomed
- Forest, not warehouse: skills/firms/jobs really destroyed
- The engine
- Invention (it exists) vs innovation (carried into use)
- Entrepreneur = new combinations, not inventor/manager/capitalist
- Schumpeterian rent: temporary, competed away, reinvested
- Five kinds: good, method, market, supply, organisation
- Why incumbents lose
- Incumbent's curse: strengths become anchors
- Innovator's dilemma: disruptor enters LOW, climbs, takes the core
- Sustaining innovation: incumbents usually WIN
- Profit anchor: richer old business = heavier leash
- Survivors self-cannibalise first, run new unit separately
- The long wave
- Boom of building + bust of clearing = one cycle
- Bust reallocates freed resources (rails, dark fibre)
- Kondratiev waves + clustering around general-purpose tech
- A lens, not a clock — periodicity is contested
- Red Queen: no moat permanent, standing still = falling behind
- Where the model lies
- Cushion the PEOPLE, not the failing FIRMS
- Not all destruction is creative: rent-seeking, hype, bubbles
- Test: did total productivity/welfare actually rise?
- Survivorship bias: count the winners, not the graveyard
- A tendency, not an iron law: direction reliable, timing open
- Destruction, not addition
Key takeaways
Creative destruction is growth as replacement: the new S-curve rises only as the old one collapses, the same customers, capital, and workers crossing over, so progress and ruin are a single event. Its engine is innovation — an entrepreneur forcing a new combination into the market for a temporary rent that imitators compete away and that funds the next wave — and innovation is far broader than a new gadget. Incumbents lose not from blindness but from the rational defence of their own strengths: the incumbent’s curse and the innovator’s dilemma make listening to your best customers and protecting your fat margins exactly what sinks you, and the rare survivors escape only by swinging the axe at their own cash cow first. Zoom out and it all runs in long waves of building and clearing, clustered around general-purpose technologies, on a treadmill where no moat is permanent. But hold the model honestly: cushion the people it displaces rather than the failing firms, remember that not all destruction is creative, watch for survivorship bias, and treat the whole thing as a strong tendency that tells you the direction of change reliably while leaving the timing genuinely open.
