Productivity, GNP and Mfg. Goods?

[Jon Shafer]

Has anyone figured out what these mean (on the retirement summary screen). I'm pretty sure that Productivity and GNP have to do with your income, and I think that Mfg. Goods may have to do with the amount of production your cities are capable of... but I really have no clue other than speculation and a bit of observation.

You can see anytime that screen pressing F11, not just when you retire.

GNP is your net income.
Mfg.Goods is your total production.
I have no idea how Productivity is calculated. Maybe it is related to lost commerce and shields (due to corruption), or maybe something entirely else.

Well, you learn something new every day!

I figured something like that, but I wasn't really sure.

Does anyone know exactly how these are calculated?

I forget something new everyday.

hm, I alwayss assumed the 'goods' thing had something to do with the amount of resources/luxuries you had.

It is kind of strange that is so very little info on this, isn't?

I suppose it is something like that:
GNP : total income
Mfg. Goods: total shields production
Productivity = (Mfg. Goods)/(number of cities)

That seems to be a pretty good explanation.

GNP: I think it's the net income, not total income (total income - total expenses)

Productivity: seems to be a good idea. Must be verified though.

As a certifiable economist, let me respond with what these measures should be.

GNP should not be net of expenses since military units, for example, are "final demand." The G in GNP stands for gross, so upkeep of buildings should not be netted out. Corruption is the channeling of GNP from the tax system, not a reduction in GNP.

Productivity should be GNP / population.

Manufactured goods is a tougher question, since it is positive before factories. I've no quarrel with total shield production being the right answer.

I definitely agree with the idea that it is strange these are not well defined by the 'pedia.

I guess that Sid didn't want to overwhelm the player with unnecessary details. The F11 table is there only to serve as a means of comparison of how well you're doing against the others. "Look, I'm the first in Mfg. Goods and Productivity! Cool! Whatever that means..."

[Tiberius]

I didn't say what it should be, but what it is. The GNP is your net income (the sum that remains after all expenses are deducted).
I checked the numbers in several ocassions, so unless I've lost completely my mathematical skills, it is definitely so. You can check this easily playing with your tax bar (F1).

The Mfg Goods is your civ's total shield output.

I don't think that productivity is GNP / population. You can have at certain moments negative GNP (I admit that this is absurd) and despite this the productivity is positive.

Edited:
If I remember corectly, there is something called "Annual income" and it gives you per capita figures. This number is, I think, calculated with the GDP/population formula.

[jshelr]

I'm outraged

Used to work for the people who calculate GDP in the Commerce Dept. If this is true, I'm going to have to break my civ Cd in two and never play the game again.

[Tiberius]

I'm not at home and can't check it now, but now I hope I'm wrong because otherwise you will blame me for your broken Civ3 CD

[SanPellegrino]

I am with Nym about this.
jshelr, you're right in Real Life productivity is measured in money not in shields But in Civ Productivity is definitely based on shields, build some factories on the same turn and watch your prod. go up. So AFAICS productivity has nothing to do with GNP in Civ 3.
