Hypotheses·fiscal·latam_extra_fiscal_rule_adoption_panel_1999_2024

Across Latin American economies 1999-2024, countries that adopted numerical fiscal rules (Chile 2001, Brazil LRF 1999, Colombia 2011, Mexico Pemex-and-budget 2006, Peru 1999, Uruguay 2006) showed measurably better fiscal-balance dispersion and lower public-debt growth than non-adopters, conditional on commodity-cycle exposure.

The pre-registered claim is (a) panel-FE estimation of public-debt share of GDP on a fiscal-rule indicator shows a negative coefficient at p < 0.10, AND (b) the within-country standard deviation of fiscal-balance-share-of-GDP is reduced post-adoption, AND (c) cumulative growth post-adoption is not lower than the non-adopter comparison panel (i.e. fiscal rules do not impose a growth penalty in this window).

PARTIAL — ATT=-22.28, p=8.45e-178, N=432, treated_countries=5; claim direction ambiguous

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

policy briefMixed or noisy

In ordinary language

In plain terms, this asks whether fiscal rule indicator is actually linked to better or worse gross general govt debt share income from 1995 to 2024.

plain answer

The evidence is suggestive but not decisive. ATT=-22.28, p=8.45e-178, N=432, treated_countries=5; claim direction ambiguous

why it matters

This matters because fiscal claims should change belief only when they survive a pre-declared empirical test.

how the test works

It compares 18 country or place units from 1995 to 2024, using a did callaway santanna design.

what was measured
What changed
  • Fiscal rule indicator
What we checked
  • Gross general govt debt share income
  • Fiscal balance share income
  • Log income pc constant
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.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

Not supported if (a) fiscal-rule indicator coefficient on public-debt share is not negative at p < 0.10, OR (b) within- country fiscal-balance dispersion does not decline post-adoption, OR (c) cumulative log_gdp_pc growth post-adoption is below the non-adopter median (i.e. rules cost growth).

Pre-registration

  • Claim: Across Latin American economies 1999-2024, countries that adopted numerical fiscal rules (Chile 2001, Brazil LRF 1999, Colombia 2011, Mexico Pemex-and-budget 2006, Peru 1999, Uruguay 2006) showed measurably better fiscal-balance dispersion and lower public-debt growth than non-adopters, conditional on commodity-cycle exposure. The pre-registered claim is (a) panel-FE estimation of public-debt share of GDP on a fiscal-rule indicator shows a negative coefficient at p < 0.10, AND (b) the within-country standard deviation of fiscal-balance-share-of-GDP is reduced post-adoption, AND (c) cumulative growth post-adoption is not lower than the non-adopter comparison panel (i.e. fiscal rules do not impose a growth penalty in this window).
  • Falsification rule: Not supported if (a) fiscal-rule indicator coefficient on public-debt share is not negative at p < 0.10, OR (b) within- country fiscal-balance dispersion does not decline post-adoption, OR (c) cumulative log_gdp_pc growth post-adoption is below the non-adopter median (i.e. rules cost growth).

Strongest opposing argument

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