fio 1.1.0

💥 Breaking changes

• miom$compute_multiregional_multipliers() output columns renamed: destination_country, destination_sector, and destination_label are now shock_country, shock_sector, and shock_label (they identify the origin of the final-demand shock).
• miom$get_regional_interdependence() now uses block sums from the spillover matrix for total_spillover_out and total_spillover_in. Removed interdependence_index; added spillover_balance and spillover_export_share.

fio 1.0.0

✨ Enhancements

• New miom() function to create multi-regional input-output models (#155).
  • New get_bilateral_trade() function to extract bilateral trade flows from multi-regional input-output models.
  • New compute_multiregional_multipliers() function to compute intra-regional, inter-regional and spillover multipliers from multi-regional input-output models.
  • New get_spillover_matrix() function to show how shocks in one region affect other regions in multi-regional input-output models.
  • New get_net_spillover_matrix() function to show net spillover effects between regions pairs in multi-regional input-output models.
  • New get_regional_interdependence() function to compute regional self-reliance and interdependence measures in multi-regional input-output models.
• New close_model() method to support closed single-region input-output models by moving household and/or government sectors from final demand to intermediate transactions matrix (#154).
• New param matrix to compute_key_sectors() and compute_hypothetical_extraction() so users can decide if should be used Leontief or Ghosh matrices when computing forward linkages (#148).
• New download_wiod() function to download World Input-Output Database (WIOD) tables directly from their website (#152).

💥 Breaking changes

• Built-in data (fio::br_2020 and fio::world_2000) was moved from {fio} to a data-only companion package {fiodata}.

💥 Breaking changes

• Removed threads slot from iom object (#95).

🛠️ Other improvements

• Fix homebrew installation instructions in README and tools/msrv.r (#105).
• Translate br_2020 dataset to English (#113).
• Fedora 36, 37, 38 and 39 from test workflow, since CRAN runners were updated to Fedora 40 (#126).

fio 0.1.2

🛠️ Other improvements

• Fixes system checks scripts to correctly handle errors when Rust and Cargo are not found.

fio 0.1.1

🛠️ Other improvements

• Update extraction.rsand multipliers.rs in order to lower minimum supported Rust version from 1.71 to 1.67.
• Set minimum version of rustc >= 1.67.1 in SystemRequirements.
• Add system checks to rustc and prompt users either install, if missing, or update when version is lower than specified in DESCRIPTION.
