Comparative institutions lab¶

Canonical target: HW05; interfaces with HW01, HW03, HW06, HW10 and HW19. Entry requires reconstruction of a strategic interaction and the difference between a causal claim and a normative choice.

Intellectual problem¶

A shared resource can fail through overuse, exclusion, inadequate maintenance or capture by those who enforce its rules. These are different mechanisms. Calling all four a tragedy of the commons obscures the diagnosis. A common-pool resource is not identical to an open-access regime, and state ownership is not identical to effective monitoring.

Read the relevant arguments in SRC-HW-LEG-011, Elinor Ostrom's Governing the Commons, and reconstruct the collective-action problem in SRC-HW-LEG-010, Mancur Olson's The Logic of Collective Action. These are distinct analytical accounts, not interchangeable endorsements of one political program. Use SRC-HW-CORE-ECON2, CORE Econ's The Economy 2.0, units on strategic interaction and institutions, as an introductory comparative bridge. Bibliographic links do not settle the validity of any particular case. CORE's CC BY-NC-ND license differs from the repository's license; this lab links to the textbook and supplies its own exercises, not adapted textbook text.

Reconstruction and bounded model¶

Model a fictional irrigation canal shared by upstream and downstream households. Specify water availability, withdrawal decisions, maintenance costs, observation limits and a rule for sharing shortages. Derive when each household benefits from breaking that rule. Then change one assumption: repeated interaction, monitoring cost, outside employment, unequal landholding or appeal rights.

Do not silently translate local categories of obligation into a universal payoff function. State what the model omits and which observations could reveal that omission. Efficiency, legitimacy and equitable distribution are separate criteria.

Comparative inquiry¶

Build two small source packets: one historical/local commons and one contemporary public service or digital commons. Select cases from different institutional and geographic settings. Record source author, date, genre, intended audience, translation and archival limitations. Include evidence from affected users, not only rule-makers.

Trace access rules, decision rights, monitoring, sanctions, repair and appeal. Compare the mechanisms before comparing outcomes. Explain whether an apparent failure reflects incentives, enforcement, external coercion, measurement, ecological change or a mistaken model. Absence from the surviving archive is not evidence that an institution or practice never existed.

Action and failure test¶

Audit a consented low-stakes shared resource: a tool library, club equipment store or shared room. Observe one maintenance cycle. Propose a reversible rule change with an appeal route and a cost estimate. No surveillance, collection of sensitive personal data or unauthorized intervention is permitted.

For assessment, receive a new packet in which apparent improvement follows both a new rule and an external subsidy. Separate the rival explanations. Then confront a system that meets its efficiency target while excluding a less powerful group. Explain why empirical success does not decide the normative dispute.

AI and defense¶

Internalize the distinctions among resource, rights, incentives and legitimacy. Reconstruct the model unaided. Retrieve local law and historical facts with source checks. AI may propose rival explanations after the initial analysis; it may not invent interviews or become the authority for a legal interpretation.

Defend an actor/rule map, two rival causal accounts, one discriminating observation, distributional consequences and a rollback plan. A strong response makes uncertainty operational. A weak response recites design principles or assumes that one country, ownership form or institutional tradition defines the universal solution.

Use examiner calibration. Independent case review and unseen comparative rounds are still required before branch saturation is claimed.
