The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 3 new columns ({'J', 'T', 'n_obs'}) and 7 missing columns ({'sigma_med', 'omega_cov', 'sigma_true', 'omega_med', 'med_fstat', 'omega_true', 'sigma_cov'}).

Trade Elasticities  BACI HS92 V202601
Importer-product-exporter trade elasticity estimates: heterogeneous import-demand (sigma) and export-supply (gamma) elasticities estimated from CEPII BACI bilateral trade data, following Soderbery (2018) and Grant & Soderbery (2024).
This dataset holds the published outputs of the estimation pipeline. The code that produces them, full methodology, and replication instructions live in the GitHub repository:
https://github.com/impex-machina/trade-elasticities
License
Data in this dataset: CC BY 4.0. The pipeline code (in the GitHub repo) is licensed separately under MIT.
What's here
Outputs are organized by pillar. The authoritative index  including
SHA-256 checksums and provenance  is data/manifest.csv in the GitHub
repo; the table below mirrors its human-readable view.
| Path | Pillar | Description |
|---|---|---|
stage1/baci_hs92_v202601_elast_country_hs4_feenstra_sigma.rds |
1 | Stage 1 sigma estimates (HLIML primary, Step 2 fallback) |
stage2a/baci_hs92_v202601_elast_regional_hs4_fixed_sigma.rds |
1 | Stage 2a regional gamma with fixed sigma |
stage2b/baci_hs92_v202601_elast_country_hs4_fixed_sigma.rds |
1 | Stage 2b country-level gamma with shrinkage + SE |
stage2b/..._fixed_sigma_summary.rds / .txt |
1 | Country-pair summary table (binary + human-readable) |
validation/liml_validation_tier1a.csv |
2 | Synthetic recovery: Tier 1a sigma grid |
validation/liml_validation_tier1b.csv |
2 | Synthetic recovery: Tier 1b sample-size convergence |
validation/se_calibration_mc_summary.csv |
3 | SE calibration Monte Carlo (4 regimes x 3 formulas) |
validation/se_calibration_mc_per_param.csv |
3 | Per-parameter calibration detail |
The three pillars: (1) the BACI HS4 empirical core, (2) synthetic
recovery of the estimator, (3) standard-error calibration. See the repo's docs/methodology/ for details.
Raw BACI data is NOT here
The raw CEPII BACI HS92 V202601 trade data is not redistributed in this dataset (it is CEPII's to distribute, and it is large). Download it directly from CEPII:
https://www.cepii.fr/CEPII/en/bdd_modele/bdd_modele_item.asp?id=37
Place it under data/raw/ in your clone of the repo. The pipeline reads
it from there.
Loading the outputs in R
The recommended path is to clone the GitHub repo and use the bundled loader, which reads the manifest and verifies checksums:
# from the repo root, after renv::restore()
source("R/load_outputs.R")
load_outputs() # downloads all manifested files to data/derived/
x <- readRDS("data/derived/stage2b/baci_hs92_v202601_elast_country_hs4_fixed_sigma.rds")
head(x)
To pull a single file directly from this dataset without the repo:
url <- paste0("https://huggingface.co/datasets/impex-machina/",
"trade-elasticities/resolve/main/",
"stage2b/baci_hs92_v202601_elast_country_hs4_fixed_sigma.rds")
tmp <- tempfile(fileext = ".rds")
download.file(url, tmp, mode = "wb")
x <- readRDS(tmp)
head(x)
