policy briefCoverage too thin

In ordinary language

Over a long period, do more market-oriented institutions translate into higher income or productivity, once the comparison looks beyond a single success story?

plain answer

This test cannot make a firm call yet. falsification rule not sharpened - auto-grader refuses to grade against the generic stub boilerplate.

why it matters

Growth claims can look convincing in single success stories. This test asks whether the pattern survives a broader comparison.

how the test works

It compares 1 country or place units from 1928 to 1940, using a descriptive design.

what was measured
What we checked
  • Log real income long run
  • Log income pc long run
  • Grain production index
what this does not prove

A single test is not the whole truth. It narrows the claim under a specific sample, time period, and method. Strong policy conclusions need the pattern to survive nearby tests, alternative data, and serious objections.

Who has skin in the game — schools predicting on this

1 school list this hypothesis as a test of their position. The chips below are school-level scoreboard outcomes, not a second hypothesis verdict.

hypothesis verdict vs scoreboard outcome

The banner verdict judges this hypothesis as written. The scoreboard asks whether each school's polarity-corrected prediction was right. Raw status is not a school win: SUPPORTED supports schools that needed SUPPORTED, but refutes schools that needed REFUTED.

Collectivised agriculture in the USSR 1930-1940 raised grain marketings sufficiently to finance industrial investment, delivering Preobrazhensky's scissors-crisis resolution despite high rural transition costs.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

The hypothesis is considered falsified if the pre-registered empirical test shows the opposite direction of the claim at conventional significance (p > 0.10), or if the primary outcome measure moves less than 10% in the claimed direction across the sample. Exact thresholds will be pinned in the variables and estimator blocks when this stub is promoted from draft.

formal test & threshold
test:      Descriptive USSR time series 1928-1940 of grain marketings index and industrial output index (Davies-Wheatcroft); falsified if marketings/grain-output ratio not at least 30% above 1928 baseline by 1933.

Single-country USSR descriptive trajectory of grain marketings, procurements, and rural-to-urban resource transfer 1930-1940. Reports cumulative magnitude versus pre-collectivisation 1928 baseline. No causal counterfactual; tests whether the Preobrazhensky-style scissors-crisis resolution is observed in marketings data.

Verdict: INCONCLUSIVE_DATA_PENDING — falsification rule not sharpened — auto-grader refuses to grade against the generic stub boilerplate. Promote the spec (replace falsification.rule with a dispositive threshold AND document the sharpening in methodology_note) before running.

Pre-registration

  • Claim: Collectivised agriculture in the USSR 1930-1940 raised grain marketings sufficiently to finance industrial investment, delivering Preobrazhensky's scissors-crisis resolution despite high rural transition costs.
  • Falsification rule: The hypothesis is considered falsified if the pre-registered empirical test shows the opposite direction of the claim at conventional significance (p > 0.10), or if the primary outcome measure moves less than 10% in the claimed direction across the sample. Exact thresholds will be pinned in the variables and estimator blocks when this stub is promoted from draft.
  • Falsification test: Descriptive USSR time series 1928-1940 of grain marketings index and industrial output index (Davies-Wheatcroft); falsified if marketings/grain-output ratio not at least 30% above 1928 baseline by 1933.

Comparison

  • Error: falsification rule not sharpened — auto-grader refuses to grade against the generic stub boilerplate. Promote the spec (replace falsification.rule with a dispositive threshold AND document the sharpening in methodology_note) before running.

Notes

Seeded from a Marxist-Leninist (Preobrazhensky scissors-crisis) claim that 1930-40 collectivisation successfully extracted agricultural surplus for industrial investment despite rural costs. Descriptive series; data quality (Davies-Wheatcroft reconstructions) requires human review.
