### Methodology
- Identification strategy: staggered difference-in-differences design. Firms enter treatment in the year they first receive state aid and remain treated thereafter; never-received firms serve as controls. Unbalanced panel covering 2016 to 2023.
- Baseline estimator: Callaway and SantAnna (2021) cohort-specific event-study aggregation:
  - ATT(c, k) = E[y_{i,t+k}(1) − y_{i,t+k}(0) | i ∈ c]
  - ATT(k) = ∑_{c∈C} ATT(c, k) · P(G_i = c | i ∈ C_k)
  - Allows heterogeneous treatment effects across cohorts and dynamic effects by event time.
- Heterogeneity analysis: separate regressions for cohorts of young firms and small firms.
- Pre-treatment comparability: cohort-by-cohort propensity score matching implemented (details in appendix).
- Comparative specification: conventional two-way fixed-effects:
  - log(y_it) = β TreatedPost_it + β_y TreatedPost_it × Young_i + α_i + γ_st + ε_it
  - Includes firm fixed effects α_i and sector-year fixed effects γ_st; noted bias when treatment effects heterogeneous across cohorts motivates Callaway and SantAnna benchmark.
- Event-study specification for parallel trends testing:
  - log(y_it) = ∑_k β_k · 1{EventTime_it = k} + ∑_k β_{k,y} · 1{EventTime_it = k} × Young_i + α_i + γ_st + ε_it
  - EventTime_it = year_t − TreatmentYear_i, with EventTime = −1 omitted as baseline.

### Data
- Main sources:
  - Firm-level balance-sheet data from Orbis (Bureau van Dijk), years 2016 to 2023. Nominal values deflated using Federal Reserve Economic Data GDP deflator.
  - State Aid Transparency database (France): around 11,000 unique firms received state aid between 2016 and 2023; includes granting date, amount, recipient national identifier, objective, and instrument type (guarantees, loans, direct grants, interest rate subsidies, tax advantages).
  - EUTL-Orbis matched dataset for firm-level verified emissions and allocation of free allowances under the EU ETS.
- Sample construction and exclusions:
  - Exclude awards under the objective of remedy for serious disturbance of the economy.
  - Exclude firms receiving aid in multiple years to simplify pre/post categorization.
  - Merged sample: more than 25 percent firms are young at aid receipt; approximately 85 percent are small.
  - Among firms in the merged sample with aid amounts available, young firms account for an average of roughly 50 percent of total aid awarded.
- Reporting thresholds (data caveats): reporting threshold was 500,000 euros until 2023 after which it was revised to 100,000 euros.
- Data limitations:
  - State aid information only from 2016 onward — some control firms may have received prior aid.
  - Transparency data is self-reported and only includes aid above thresholds — potential under-reporting of smaller recipients could bias estimates toward underestimating treatment effects.
  - Orbis limited coverage of small and young firms, though share of small firms in merged sample comparable to Transparency Database.

### Main empirical findings
- Overall average effect on sales:
  - Average effect on sales is small and statistically insignificant: 2.4 percent.
- Strong heterogeneity by firm age:
  - Young firms (aged below 10 years at treatment) experience, on average, a large increase of 71 percent in sales, with the effect emerging immediately after treatment and remaining economically and statistically significant throughout the sample period.
  - Older firms show small, negative, and statistically insignificant responses for sales, productivity, and employment.
- Heterogeneity by firm size:
  - Targeting by firm size appears less effective:
    - Small firms experience modest improvements; sales increase by roughly 12 percent above the overall estimate, but effects are smaller and often statistically insignificant relative to young firms.
    - Large firms’ sales decline on average, though estimates are statistically insignificant.
- Private financing / crowding-in:
  - Young firms increase their external debt in years following state aid, suggesting potential crowding-in of private financing; older firms show little change in borrowing behavior.
  - Note: part of the rise in external debt may reflect expanded pandemic support measures not fully captured in the data.
- Sectoral targeting and aid objectives:
  - R&D aid: strongest response in high-technology sectors, particularly for young firms; little measurable effect outside high-tech sectors.
  - Energy aid: strongest impact in manufacturing, with positive effects across firms but more pronounced for young beneficiaries.
- Emissions and the green transition (associations, not causal):
  - Sample: EU ETS-compliant manufacturing firms in France receiving energy and environmental aid; emission intensity defined as verified ETS allowances (tons of CO2) per thousand USD of sales.
  - Regression: Emission Intensity_i,t = β_0 + β_1 price_C,t + β_2 aid_i,t + β_3 price_C,t × aid_i,t + α_i (with firm fixed effects).
  - Estimates:
    - A one dollar increase in carbon prices tends to lower emission intensity on average by 0.01 tons of CO2 per $1,000 of output.
    - The reduction is twice as large for firms receiving energy and environmental aid: around 0.02 tons of CO2 per $1,000 of output.
  - Interpretation: findings point to a transition channel where state aid helps firms reduce effective marginal abatement costs; caution urged because the carbon emissions sample is skewed toward large manufacturing firms and sample sizes are small.

### Policy implications and recommendations
- Prioritize age-based targeting:
  - State aid is most effective when directed to young firms (below 10 years), which exhibit large and persistent gains in sales, productivity, and employment and show crowding-in of private debt.
- Reassess size-based targeting:
  - Size-based targeting (small vs large firms) appears less effective; size-based policies risk distorting firm sizes and producing inefficient allocation.
- Match aid objectives to sectoral conditions:
  - R&D support is most effective for young firms in high-technology sectors; energy aid is most effective in manufacturing, especially for young beneficiaries.
- Design aid to support the green transition:
  - Energy and environmental aid can amplify the emissions-reducing effect of carbon pricing (suggestive evidence of a larger emission-intensity response among aided firms); consider aid that lowers upfront costs of adopting lower-emission technologies rather than simply compensating carbon costs.
- Balance firm-level gains with market effects:
  - Firm-level benefits (especially for young firms) should be weighed against possible negative spillovers on competitors and broader market distortions.

### A.2 Methodological details and sample construction
- Sample exclusions:
  - Exclude firms in NACE sections P to U (education, health, arts, and other non-market services).
- Sector classification:
  - High-tech sector: Information and Communication (NACE Rev. 2, Section J) and Professional, Scientific and Technical Activities (Section M).
  - Manufacturing sector: Manufacturing (Section C) and Electricity, Gas, Steam and Air Conditioning Supply (Section D).
- Aid variable:
  - State aid treated as a binary variable due to aid amounts sometimes reported as ranges.
- Aid classification:
  - Distinguish energy, energy and environmental, and research and development aid via keywords extracted from objectives and titles (full lists in Figures 6, 7, and 8).
- Outcome variables:
  - Log transforms applied above minimal positive thresholds (y_it > 1).
- Propensity score matching (PSM):
  - Cohort-by-cohort PSM.
  - Baseline year b = g − 1; firm treated in cohort b if aid receipt occurs in b + 1.
  - Control group includes cohort-treated firms and firms never treated.
  - Propensity score uses pre-treatment firm characteristics: sales, sales growth over three years, total assets (all in logarithm and lagged), firm age and number of employees in logarithm, and sector fixed effects.
  - Nearest-neighbor matching (five neighbors) on the region of common support.
  - Firm-level weight constructed: 1 for treated firms; match weight for controls.
  - Re-estimate event-study on matched sample with analytic weights, absorbing firm fixed effects (α_i) and sector-year fixed effects (γ_st).
- Programming:
  - Used csdid (Stata) package on Stata version 18.5 and 19.5.
