El Salvador's fiscal trajectory under Bukele (2019-2024) shows improvement in the primary balance and stabilisation (or modest decline) in debt-to-GDP after the 2020 COVID spike, achieved via a combination of: (a) the 2022-2023 bond buyback / liability-management operations, (b) the 2023 tax reform (lower rates with base-broadening and improved compliance), and (c) IMF-signalled fiscal consolidation culminating in the Dec 2024 $1.4bn Extended Fund Facility. The pre-registered claim is that under a panel decomposition framework, Salvadoran primary balance improvement 2022-2024 exceeds the Central American peer-group average by at least 1.5 percentage points of GDP, and that the dominant channel is spending compression + debt-service reduction via liability management, not a revenue-side tax-rise (i.e., the Laffer-style lower-rate / broader-base conjecture).
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if any of: (a) the panel-FE coefficient on the Bukele-era indicator for primary_balance_gdp is not positive and significant at 5%, OR (b) the coefficient on general_government_debt_gdp is positive and significant at 5% (i.e., debt ratio rose rather than stabilised/fell), OR (c) the primary-balance improvement versus peer-group average over 2022-2024 is less than 1.5 percentage points of GDP, OR (d) the decomposition shows the dominant positive channel is revenue-side with expenditure compression accounting for less than 40% of the primary-balance improvement (this would refute the spending-compression/liability-management story in favour of a tax-rise story inconsistent with the stated reform content).
formal test & threshold
test: panel_fe_plus_decomposition_plus_peer_gap threshold: panel_FE_beta(bukele_era, primary_balance) > 0 at p<0.05 AND panel_FE_beta(bukele_era, debt_gdp) < 0 at p<0.05 AND (primary_balance_SLV_2022_2024_mean - primary_balance_peers_2022_2024_mean) > 1.5 percentage points GDP AND expenditure_channel_share_of_improvement >= 0.40

Primary: two-way FE panel with SLV as treated from 2019Q2, Central American peers as never-treated control; outcome is primary balance and debt/GDP. Decomposition: separately regress revenue_gdp, expenditure_gdp, and interest_gdp on the Bukele-era indicator and sub-treatment binaries (buyback, tax reform) to isolate which channel explains the primary- balance change. Secondary: synth_did with peer donor pool as robustness.

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 IMF GFS series for El Salvador and peers (annual general-government fiscal aggregates) plus EMBI+ spread series for market-perception controls. The decomposition test is the load-bearing falsification criterion — the literature is mixed on which channel dominates Latin American fiscal adjustments of this size.
