Calculating present day value

Source: vignettes/speciesValue.Rmd

The SPPVALUE field in the STOCKEFF database is the value of the catch on the date landed. To compare SPPVALUE over time, these values need to be converted to present day dollar amounts. This is achieved using the Implicit Price Deflator of Gross Domestic Product (GDPDEF) from the Federal Reserve Bank of St Louis. This index is calculated on a quarterly basis. In comlandr we hold the deflator constant for each quarter.

  • SPPVALUE in STOCKEFF is only available from 1981 to present day.
  • comlandr allows the user to adjust the value to any reference date required. See arguments refMonth, refYear in get_comland_data()
