Ethiopia's Grand Ethiopian Renaissance Dam (construction 2011-2024, partial commissioning from 2022) was projected to raise generation capacity by ~5 GW and shift the country's electricity-supply frontier outward.

The pre-registered claim is that, despite the contemporaneous Tigray war shock (covered in a separate hypothesis), Ethiopia's per capita electricity consumption rose at least 40% from 2011-2024 and electrification share of population rose by at least 25 percentage points, both at rates exceeding the Sub-Saharan African low-income peer average (Tanzania, Uganda, Kenya, Rwanda, Sudan, Mozambique). The null counter-claim is that, given GERD construction delays, Tigray war disruption, and persistent transmission-network bottlenecks, the GERD's actual delivered effect on consumption and electrification is statistically indistinguishable from the SSA-peer trajectory.

confidence cueThe result is useful, but not decisive. Treat it as a clue, not a settled conclusion.

policy briefMixed or noisy

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

The evidence is suggestive but not decisive. mean_gap=-132.4, |gap|/pre_sd=2.7, p_perm=0.714 (gap below 0.5×pre_sd or placebo p≥0.10)

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 7 country or place units from 2005 to 2024, using a synth did design.

What changed
  • Gerd construction indicator
What we checked
  • Electricity consumption pc
  • Electricity access share
  • Real income pc
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

2 schools 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.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

Not supported if EITHER (a) Ethiopian per-capita electricity consumption growth 2011-2024 is less than 40% AND less than the SSA donor-pool average, OR (b) electrification access rises by less than 25 percentage points 2011-2024, OR (c) the synth-DiD CATT on log(electricity_consumption_pc) is statistically indistinguishable from zero (p_perm > 0.10), indicating GERD's projected supply effect did not materialise in measured consumption due to delays and transmission bottlenecks.

Pre-registration

  • Claim: Ethiopia's Grand Ethiopian Renaissance Dam (construction 2011-2024, partial commissioning from 2022) was projected to raise generation capacity by ~5 GW and shift the country's electricity-supply frontier outward. The pre-registered claim is that, despite the contemporaneous Tigray war shock (covered in a separate hypothesis), Ethiopia's per capita electricity consumption rose at least 40% from 2011-2024 and electrification share of population rose by at least 25 percentage points, both at rates exceeding the Sub-Saharan African low-income peer average (Tanzania, Uganda, Kenya, Rwanda, Sudan, Mozambique). The null counter-claim is that, given GERD construction delays, Tigray war disruption, and persistent transmission-network bottlenecks, the GERD's actual delivered effect on consumption and electrification is statistically indistinguishable from the SSA-peer trajectory.
  • Falsification rule: Not supported if EITHER (a) Ethiopian per-capita electricity consumption growth 2011-2024 is less than 40% AND less than the SSA donor-pool average, OR (b) electrification access rises by less than 25 percentage points 2011-2024, OR (c) the synth-DiD CATT on log(electricity_consumption_pc) is statistically indistinguishable from zero (p_perm > 0.10), indicating GERD's projected supply effect did not materialise in measured consumption due to delays and transmission bottlenecks.

Strongest opposing argument

Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.

Notes

Data-gated on EEU (Ethiopian Electric Utility) reports — partial coverage. Hydropower output is rainfall-dependent; control includes rainfall anomaly. The Tigray war hypothesis covers the 2020-2022 collapse period; this hypothesis tests the long-run GERD effect through the war window.
