Solow-Swam Model

[victorguedes]

Hey,

 

This may sound very basic, but I'm working on the Solow-Swam model and I wasn't able to figure out which data to use as Capital (K). Would the gross fixed capital formation work? Also, can I use the percentage of gross fixed capital formation over the GNP as my alfa?

 

My aim is to make use of the most simple standards just as an approximation to further compare the TFP's trend (over 60 years) with other data.

 

Thanks!
