ASSESSMENT · Chapter VI.02 — Ostrom, Fully Applied

Three instruments: a ten-point quiz, eight reflection questions, five essay prompts. The quiz checks comprehension rather than recall. The reflections are private and first-person. The essays are arguable from more than one side.

THE QUIZ — ten points

Four on recall.

1. State Ostrom's fourth design principle in full, and name the two things it requires that "have monitoring in place" does not.

Monitors, who actively audit CPR conditions and appropriator behaviour, are accountable to the appropriators or are the appropriators. It requires, first, that both the resource condition and user behaviour are audited; and second, that the monitors are accountable to the people being monitored, or are those people. One mark for the compound audit, one for accountability. An external inspectorate satisfies the paraphrase and fails the principle — credit any answer that says so.

2. How many studies and how many cases did Cox, Arnold and Villamayor-Tomás code, and what was the mean support score?

91 studies, 77 cases, mean 3.73 out of 5 — which the paper itself glosses as slightly below moderately supportive.

3. Cox et al. split Ostrom's eight into how many, and which four of the original eight were left untouched?

Eight became twelve. Principle 1 split into user boundaries, resource boundaries and their congruence; principle 2 into congruence with local conditions and congruence of appropriation with provision; principle 4 into social and environmental monitoring. Principles 3, 5, 6, 7 and 8 were left as they were — that is five, and an answer naming any four of them takes the mark.

4. What did Baggio et al. find about whether any single design principle is necessary and sufficient?

No single principle is both. 1B, 2B, 4B and 6 appeared as necessary but not sufficient in most successful configurations; the absence of 2A, 2B, 4B and 5 raised the odds of failure; and more than eight principles together greatly raised the odds of success regardless of resource type.

Four on application.

5. A colleague's slide says: "The best-evidenced of Ostrom's principles is environmental monitoring — 4B, very strongly supported by Cox et al." What is wrong with the slide?

The letters have been read off the wrong table. In the coding for the meta-analysis, 4A was the presence of monitors and 4B their accountability to users; the "very strongly supported" verdict attaches to that. In the reformulation, principle 4 splits along a different line entirely — social versus environmental monitoring. Full marks require naming both tables and stating what 4B actually was in the one that carried the finding.

6. You are scoring a shared internal platform and it scores 3 on ten of the twelve and 1 on two. A director asks what the probability is that it survives five years. Answer her.

That the score does not license an answer to that question. The score is a diagnosis: it names which two conditions are unmet, and those are the work. Converting points into a probability requires a likelihood ratio — how much more often each principle is present in commons that endure than in ones that die — and no such ratio has been published for a digital commons, because the denominator requires the dead. The strongest answer offers her the thing the score does give: the two named gaps and what it would cost to close them.

7. Why does monitoring cost so little in a digital commons, and what is the hidden price of that?

Because the evidence of a violation is a byproduct of appropriation — every edit emits a diff automatically, so the record is produced by the act itself rather than by a funded inspector. The hidden price is that cheap monitoring tends toward total monitoring: rejection becomes instantaneous and impersonal, and a commons can enforce itself into sterility. Credit any answer naming the Törbel hay rule or contiguous irrigation order as the physical analogue.

8. A sponsor holds the servers, the trademark and the terms of service for a commons you are designing. The community has full rule-making authority in practice. Which principle is at risk, and what clause fixes it?

Principle 7 — minimal recognition of the right to organise. The right exists at the sponsor's pleasure until it is written down. The fix is a reserved matters schedule: the sponsor's power to override is limited to enumerated grounds, exercisable on stated notice, with a written reason, and appealable to the conflict panel. Credit any answer noting that principle 7 is a negative — the sponsor need not bless the arrangement, only refrain from challenging it — which is why the clause is achievable.

Two that require the arithmetic to be done.

9. A commons scores 29 out of 36 on the twelve-principle rubric, so the sum of score/3 across the twelve is 9.667. The prior odds of enduring are 0.4658. Compute the posterior probability of enduring if the per-principle likelihood ratio is 1.2, and again if it is 4.0. Then say what the pair of answers means.

W = log2(LR). At LR = 1.2: W = 0.2630, evidence = 9.667 × 0.2630 = 2.54 bits; posterior odds = 0.4658 × 2^2.54 = 2.714; P = 2.714/3.714 = 73.08 %. At LR = 4.0: W = 2.0000, evidence = 19.33 bits; posterior odds = 0.4658 × 2^19.33 ≈ 308,000; P ≈ 99.9997 %. The meaning is the point of the question. The same score on the same institution supports anything from "probably" to "practically certain", and the quantity that decides which — the likelihood ratio — has never been measured. A band 16.79 bits wide. Credit any method reaching roughly 73 per cent and roughly five nines. Full marks require the conclusion: the score is a diagnosis, not a forecast.

10. Nine organisations want to share a reference dataset. Consortium governance costs £45,000 attestation plus £180,000 secretariat plus £30,000 panel reserve. The alternative is bilateral agreements at £12,000 a year each. Does the consortium clear, and at what member count does it start to?

Governance = 45,000 + 180,000 + 30,000 = £255,000. Bilateral pairs = n(n-1)/2 = 9 × 8 / 2 = 36; upkeep = 36 × 12,000 = £432,000. The consortium clears, saving £177,000 a year, 41.0 per cent of the bilateral cost, an advantage of 1.69×. The crossover: at n = 7, 21 × 12,000 = £252,000 < £255,000 — bilateral still wins. At n = 8, 28 × 12,000 = £336,000 > £255,000 — the rulebook wins. Eight members. The stronger answer states why: agreements grow as n² and a rulebook grows as n, so below eight members a commons is an expensive way to do something a few contracts would do better — and saying so is what makes the rest of the proposal credible.

REFLECTION — eight questions, for one person and a pen

These are not for a room. Write the answers by hand if you can; the slowness is the point.

Name a shared thing in your life — a household, a codebase, a group chat, a piece of land, a reputation — that has held for years without written rules. Which of the twelve is it quietly satisfying, and who is the monitor?

Where do you appropriate more than you provide? Answer it about attention and goodwill before you answer it about anything material, and do not soften the number.

Think of a time you were sanctioned in a way that was proportionate to the context rather than the offence. What did that do to your relationship with the rule afterwards?

Where have you treated a score as a probability? What did you assume about the conversion factor, and had you ever seen it?

What is the commons you belong to whose right to make its own rules rests on somebody else's forbearance? What would it cost you to ask for that in writing — and is that cost real or imagined?

Recall a dispute you did not raise because raising it was expensive. What was the cost, exactly, and what would have had to change for you to have raised it early, while it was still small?

Which of your own failures has never been written up anywhere? What would somebody counting the base rate have learned from it?

You have now read the evidence behind a list you probably already believed. Where else are you carrying a well-travelled list whose empirical record you have never looked at? Name one, and write down the first source you would go and read.

ESSAY PROMPTS — five

Each is arguable from more than one side. Each requires at least one source the chapter cites and at least one it does not.

1. The denominator problem. The chapter argues that the design principles rest on a sample selected on survival and documentation, and that the base rate is therefore unknown. Argue either that this is a fatal limitation that renders the principles descriptive only, or that a body of evidence built from convergent, independently evolved institutions carries a kind of validity that cohort studies cannot supply. Use Cox, Arnold and Villamayor-Tomás directly, and at least one source on selection bias or survivorship in social science that the chapter does not cite.

2. Is a digital commons a commons at all? Ostrom's principles were derived for subtractable resources — a fish taken is a fish gone. Knowledge is non-rival. Argue whether the principles transfer, and if so, what carries the load in their place: is the congested resource the artefact, or is it the attention and goodwill of the maintainers? Engage Hess and Ostrom's Understanding Knowledge as a Commons, and one source on non-rival goods or platform governance the chapter does not cite.

3. The Fram clause. In June 2019 the Wikimedia Foundation imposed a project-specific ban over the English Wikipedia community's head, and the community's response was severe. Write the case that this was a violation of principle 7 that should be contractually prevented in any commons with a sponsor — then write the strongest case that a legal owner of infrastructure cannot responsibly contract away the power to act, and that principle 7 is therefore unattainable wherever anyone must own the servers. Conclude with which you find more persuasive. Use the chapter's account, and at least one account written from the Foundation's side.

4. Configurations against components. Baggio and colleagues found the principles configural, with only 27 complete cases against 2,048 possible configurations — 1.32 per cent coverage. Argue either that configurational methods are the right tool for institutional analysis and the coverage problem is a funding problem, or that qualitative comparative analysis at this coverage cannot support causal claims and that the field should return to component-wise testing at larger n. Engage Baggio et al. directly, and one methodological critique or defence of QCA the chapter does not cite.

5. The crossover, and what it excludes. The chapter offers a member count — eight — above which a rulebook beats bilateral contracting, and argues that below it a commons is the wrong structure. Argue the counter-case: that the value of a commons is not reducible to transaction-cost economics, and that structures which fail the arithmetic may still be right because of what they produce in the people inside them. Then say what you would actually recommend to a five-member group. Use the chapter's arithmetic, and one source on the non-instrumental value of collective ownership or on transaction-cost theory that the chapter does not cite.
