. I think for a young single 2000US is very comfortable living.
I agree, but the OP is only being offered $5000 pesos per month gross income:
"Their offer is AR$5000 gross plus aguinaldo, with a possible annual performance bonus, 2 weeks paid vacation, and private health insurance.
With the current exchange rate that is roughly 16,000 USD per year, and after I tried to adjust for Purchasing Power Parity I came up with 28,000 USD."
I don't think the "Purchasing Power Parity" will be a positive factor, either. We all know electronics are expensive and clothes are surprisingly low quality(for the money).
Even if his company can get a guarantee for him he would have to have more than $1000 USD to furnish an apartment unless he buys everything used, and that isn't easy for a newcomer to do (no yard, garage, or moving sales in BA...except for expats fleeing Argentina). The $28,000 USD figure is simply wishful thinking.
The offer of $16,000 leaves him $8,000 USD short of the $24,000 he would need to actually spend to have the nice life in BA that you enjoy so much, and I fear the OP's net pay would only be about $1,200 per month.
