How does Commerce work?

Is commerce just a flat percent bonus to daily income in a city?

For example, if a bank increases commerce by 7%, and my city has an average income of $2.35, would a bank increase that city's income by 7% of $2.35?

 

This makes the most sense to me, but the tooltip description doesn't give details on the math of it.

Sheepy can correct me on this...In Alpha, prior to changes (and I believe he said it still works out the same), each percentage of commerce works out to $0.05 gross. It's easier for me to know what each 1% equates to.

 

So a bank would equal $0.35 before bonuses and tax rates multiplied.

At the max commerce rate (100%), your citizen's average income is tripled. A 7% increase in commerce would translate to a 14% increase to your citizen's average income.

These statements appear to be compatible with each other after a bit of math-checking. Thanks!

One easy rule of thumb is that one citizen will net you $0.725 daily from the taxes regardless of economic policies. You can do your calculation from there.

 

You know, maybe Sheepy should just remove the '%' from the commerce rates, since 100% kinda implies that it doubles the average income instead of tripling it.

The commerce rate is just the indicator of wealth in a city. I don't know why 100% would imply a double in income, it simply means a city is at its max for how much money the people can make.

Idk about others, but the first thing that came across my mind when seeing the commerce improvement the first time was "Wow lookie here! Double the income!". When the number involved is capped at 100%, I think it's natural to see it as +100% income.

The way it was, 100% would add $5 to the base of $2.5 So, it's more like triple income.

Correct, that is how it works out. The maximum people can make in a city is 3x their avg income. 100% simply is saying they've reached their max potential, whereas 85% or 45% or w/e just means they're a part of the way there. I'm not sure where Atzuya got 2x out of 100%.

Sheepy, all Atzuya is saying is that intuitively, when you see 100% commerce and all you know is that commerce improves income, it's natural to assume that 100% means 100% increase in income. It's wrong, and any rudimentary experiment with the system would show that it's wrong, but it's not as bizarre as you're making it sound.

 

That isn't to say that you should double the values and raise the cap to 200%, or that you should half the effectiveness of commerce on income. It's just to say that the result isn't apparent on its face without reading in more detail from the descriptions or experimenting with commerce improvements.

I can understand this assumption, the part I was addressing was:

Yeah, I meant t'was the implication I got from the first time I seen the commerce thing. I had quite a hard time wrapping my mind around it back then, and I imagine there are some other people who had the same kind of brief confusion.

 

I'm terrible with words :ph34r:

Nah, there's nothing intuitive at all with the commerce system. 100% commerce means 100% commerce. You need to watch your gross income before and after buying a commerce improvement to really find what commerce rates are worth under your economic policy. Or, you can trust that the policies really are cosmetic and that between gross income and tax rate it will come out the same. So, assume $0.05 per commerce percentage x bonus x (original) tax rate of 29%

Does anyone know at what stage certain improvements are profitable?  For example, I assume a city with 200 infrastructure would not benefit financially if they invested in a mall or stadium.  Is there a generally understood infrastructure level that should be reached before getting a certain commerce based improvement?

Yes, but that is highly classified basic math. Population x $$$ from given improvement plus bonuses minus taxes etc. Then figured the return on capital for the initial cost. Then you'll have a good idea when an improvement is profitable and how many days it'll take to realize a profit.

What is the best way to let my alliance know to check their Alliance trade screen?  I don't want to spam anybody, but I would like them to be able to get resources from me at a decent discount off of global prices.

Well, that seems rather cynical.  I like it.
