My turn Sally...
1. What makes the average price of a product in a specific country go up? or down?
Players determine the price to an extent. The NPC starts off with a low price put as players sell goods for a higher price the average rises.
2.Does that price correlate to the average quality in the column beside it?
Look at the Stats page. The average price and quality are listed next to each product. They go hand in hand. The average price listed is for the average quality listed.
Also, keep in mind, there are Price Caps on every item. At some point the average price, on the Stats page, will quit raising even if people are selling the goods for higher prices.
Example: Pullovers
I sell my Pullovers for 1300c but the average price on the Stats page is 600c. Even when 99% of the Pullovers sold are mine.
3.How do supply and demand affect the prices in the stores?
Demand does not effect the stores in Kapilands. (Which is a very sad thing.)
Supply only comes into effect when Supply exceeds Demand. At which point sale times increase to an insane number making it almost impossible to sell the item no matter the price.
4.Why is it that when flour has a demand of 108 million in Germany, there's only a supply of 6 (Realm 2), shouldn't this be a sign of great profits possible?
As I stated on #2, Demand doesn't effect price or sales time at all.
But, in Kapilands, not all products are equal. There are a select few that really make the cash while others have lower or even negative profits.
5. How does the total number of inhabitants in Kapilands affect the game? Is there a way to affect the rate of population growth in the game?
Employees plus a base number, I forgot the base number, equal the population of each country Kapilands. Demand is determined by the population in that country.
Population grows when new employees are added to each country. So, if you want to increase Demand in a country expand your buildings in that country and hire new workers.
6. How does the ratio of jobs and population affect the game? Do the prices drop if the ratio increases? Does it even matter? Does population grow only when new buildings are built or does it always grow no matter what? And if it does depend on the buildings, what happens when no new players come in, not many new buildings are built and the population keeps rising but there are no new jobs?
Population doesn't effect anything besides Demand. Prices are determined by Players.
7. Are there any equations to portray any of the above? Have the creators released any algorithms? Has anyone tried to derive any or figure any of them out?
I personally think it'd help a lot of people if they could understand what factors affected the game and how? An what factors DO NOT affect the game?
No, Upjers has never released any algorithms they have use in the game.
As to people figureing things out, sure. KapiTools(kapitools.de) figured out all shorts of things to create their calculators.
As to what factors do not effect the game... ask when you think of something and we will answer.
8. How often does the stats page update, so if I sold 10000 of a product, when will I see the supply page add 10000 to the supply count?
The Stats pages update every 20 to 26 hours or so.
