v2.3.0

Added

• Get Deflators Functions: New functions to retrieve deflator data directly as DataFrames without requiring user data:
  • get_imf_gdp_deflators(), get_imf_cpi_deflators(), get_imf_cpi_e_deflators()
  • get_wb_gdp_deflators(), get_wb_gdp_linked_deflators(), get_wb_cpi_deflators()
  • get_oecd_dac_deflators()
• Get Exchange Rates Functions: New functions to retrieve exchange rate data directly as DataFrames:
  • get_imf_exchange_rates(), get_wb_exchange_rates()
  • get_wb_ppp_rates(), get_oecd_dac_exchange_rates()
• Flexible Filtering: All new functions support optional filtering by countries and years via countries and years parameters.
• Component Breakdown: include_components=True parameter for deflator functions to retrieve price deflator, exchange deflator, and exchange rate components separately for analysis.

Changed

• Documentation: Updated README.md with extensive examples of the new get deflator and exchange rate functions.
• Documentation: Added new section "Getting Deflators and Exchange Rates Directly" with common use cases.

Use Cases

The new functions enable:

• Inspecting and analyzing deflator trends over time
• Pre-computing deflators for custom calculations
• Understanding the components that make up deflators
• Retrieving exchange rates for analysis without converting data

What's Changed

• Add get functions by @jm-rivera in #31
