GNP. What is the exact formula?

[Giaur]

I wonder what is the relation beetwen GNP (abstract thing) and research (real thing). I will be thankful for any data.

 

[Lao Tzu]

If you'r running CE with high slider position, big GNP = quick research.
And if your economy relies on specialists even negative GNP is not so bad.

This gives the best explanation of how the Demo Screens work I've seen

2. Demographics Screen
GNP- The GNP (Gross National Product) is the total of the raw commerce you produce on each turn minus your expenses (city, civic, unit maintenance etc.) Your raw commerce is the gold coins you get from all your worked tiles, the palace, specialists and trade routes. It does not include commerce gained from holy cities and city improvements like markets and banks. When you look at the F2 screen it shows your commerce and income after all the improvements. The commerce figure (left column) also has science commerce which includes the effects of universities etc. However on the F1 screen in the coins column it shows the raw commerce value each city is producing, add these up and subtract you cost and you will get your GNP figure. Therefore it is entirely possible to have a negative GNP but run a profit and continue research at a good pace.

I would say T-Hawk summed it up pretty well in his Epic IX report.

So I guess GNP cannot be higher than research when civ runs at 100% research ... That's is negative. One civ in my game has GNP 600, so research is more than 600. This is high-level game and this civ must run at 100% research ...

edit: I will at this Epic, when I take a rest first ...

GNP translates commerce minus upkeep and maintenance (I believe).
This is somewhat relevant if you play a cottage economy.
It's totally irrelevant if you play SE.

It's a pretty bad stat, actually. I wish they would just show net gold + beakers instead. Far more relevent.

Yeah, adding specialists and multipliers would be much better and more accurate. It can't be that hard to code. Well, actually it might, I have no idea.

Agreed, it'd be more useful, but I suppose the idea was to not give away information in the graphs that couldn't be gleaned from what you can see on the map.

The raw commerce the AI gains you could theoreticaly figure out yourself, by adding up all the coins their tiles generate. And upkeep you could also kind of guess by the number of cities. if the graph contained the net results, you could get additional information about how well the cities are developed and how much revenue is allocated to research/commerce, and in a way that's cheating.
