How to update the GDP data- I found laborproductivity

[Metondar]

I am beginner in GCAM, and I tried to update the socioeconomic data using socioeconomic xml file. I updated the population, but the section of the GDP is using laborproductivity. How can I calculate those updates for the laborproductivity. I have the data for Population and GDP until 2070.

Are you familiar with how to work with gcamdata?

If yes, there is a socioeconomics file \input\gcamdata\inst\extdata\socioeconomics\SSP_database_v9.csv that has all the GDP information. You can directly change the country GDP there and rerun the data system to produce new socioeconomics.xml.

If not, you can calculate Labor Productivity using the following expression
Labor Productivity = [ ((GDPy1/Populationy1) * (Populationyy0/GDPy0)) ^ (1/(y1 - y0) ] - 1. Make sure you're using GDP MER (market exchange rate) for your calculations.
