by provincialist » Sat May 12, 2012 2:20 pm seems that i just have to put it in front:
it's a formula to determine value of things comparatively each other in numerical expression, so you can meashure, how many q20 honeybuns one q90 carrot cake worths and damn pts were justified somehow. The thing about coins there is just to find out, wich item costs 1 and can be easily used to pay in addition when cost of goods is a bit lower than you need. Gold and silver coins are mentioned to illustrate that common ratio in not violated in calculation.
Hello guys. I know that lots of people try to start a coin system in their villages or just experience troubles with figuring out, wich price would be fair when selling or buying goods. Well, i'd like to share my formula and probaly get a good critics about it. All that is written below, is just my thoughts on meshuring how useful object is, and how much labour you need to put in it to get produce it yourself. Also, it's just a nominal price of object, that doesn't mean, that it is always fair, demand can and will correct it in some particular situations.
Closer to fomula, what it does:
- Measures labour, wich you need to put in production to get object by yourself
- Measures lp that object gives and it's efficiency
- Gives the answer, in what currency object's value is measured
What it doesn't:
- It doesn't take into consideration cost of fuel and tools
- It doesn't take into consideration cost of side products from production process (if you count rabbit meat price - forget about bone and fur)
- It doesn't take into consideration low skills wich cap Q
- It doesn't take into consideration that raw materials needs indefinite time to be found (for example, mussels, rabbits and so on)
- It doesn't take into consideration that the persons, who produce goods may have wrong pesonal believs (if you making silk with full industry - that's your problem, pal) or does other not optimal stuff
- It doesn't take into consideration that someone don't have enought int for curio, so it's not valuable for him
Well, here is it (may impress as bulky thing wich can be never used comfortably, but read below, it's simple to use and you don't need to use it full length constantly):
Nominal price for non-curio objects:
Pn = Qm*(1+(100/X)*Sp)*(1/N)+T/N
Qm = sqrt(Q/10), it's quality multiplier (when q=10, or object has no q, it's just 1)
X = chance of success (you'll need it only in metals and pearls)
sP = summ of pn of all raw matirials if they were q10
Q = q of output product
T = time of production process in hours, if it's less than 1 hour, T = 0. In fact last addendum is not 0 only for steel, cheese and silk, in most cases we don't need it
N = ammout of production per one cycle (for example, when harvesting crops, N = 3, but when making bricks with full klin N=1, cause 1 clay gives 1 brick and so they should be counted separately)
For curio objects (will speak of them later, but formula is here):
Pn = (Pn+Pc)/2
while curioprice Pc = (Qm*Lp)/(t*S)
Lp = base lp
t = study hours
S = size in tiles
Now let's test it and see how it works. Counting cost of q10 unboiled mussel: Pn = sqrt(10/10)*(1+(100/100)*0)*(1/1)+0/1 = 1*(1+0)*1+0 = 1
In fact, when you know that q=10, chance is 100% and there is only 1 at a time produced, and it's less than 1 hour to make item, formula is just (1+0)*1 = 1 , pretty simple
So nominal price of one unboiled q10 mussel is 1 imaginary coin. We don't know what coin is it, but we'll find out later. If you still reading - i admire your patience, hope you got some more
Boiled q10 mussel Pn = 1*(1+1*1)*1+0 = 2, and if it is q30 Pn = sqrt(30/10)*2 = 1.73*2 = 3.46
Now let's find out wich coins formula implies, coin must value 1 coin
Ore Pn = (1+0)*1 = 1
Cast Iron bar (chance is about 20% with full industry) Pn = (1+(100/20)*1)*1 = 6
Bar of wrought iron (chance about 30 with industry) Pn = (1+(100/30)*6)*1 = 21
Pn for q10 Steel Bar (now we need time, T=56) = (1+21)*1+56/1 = 78
That's close..
1 q10 steel coin Pn = (1+78)*1/100 = 0.79
and let's count for q16 steel coin: sqrt(1.6)*0.79 = 0.999 that's it!
So, the state will have profit at least for 0.001 from coin, while pressing them from steel with Q<17. That's how we invented capitalism!
And formula meshures value in tech Q steel coins.
Now let's turn back to curiosities:
Let's count for a dandelion q20:
Pc = (1.4*50)/(0.67*1) = 46.9
Pc = (1.4*(1+0)+46.9)/2 = 24.15 .. turns out that dandelion costs about 1/4 bar of steel
But don't worry it just shows that demand will correct prices.Let's count something valuable with common ratio. Well, 1 pearl q10 offenly wtb for 5 q20 edels (but rarely sold for such price, lol).
Pn for pearl is a tricky, it's curio and it has 1% chance of succes when boiling mussels
Pn q10 pearl = (1*(1+(100/1)*1)+(1*5000/1*1))/2 = (101+5000)/2 = 2550,5 coins
And for Edelweiß q20 Pn = ((1.4*(1+0)*1)+(1.4*4000/7*1))/2 = (1.4+800)/2 = 400.7
So q10 pearl equals about 6 q20 Edelweißes.. sounds like true to me..
And the last one: silver and gold.
Their smelting chances are unknown, but are about 5% and 1%, and that would be nuggets, not bars. They have no Q, so Qm should be counted as 1
So:
Silver nugget: Pn = 1*(1+(100/5)*1)*1+0 = 21
Bar of silver: Pn = 1*(1+1*210)*1 = 211 (sounds ok, bar of silver costs about 2 steel bars)
Silver coin: Pn = 1*(1+211)/100 = 2.12
Gold nugget: Pn = 1*(1+100/1)+1 = 101
Bar of gold: Pn = 1*(1+1010)*1 = 1011
Gold coin: Pn = 1*(1+1011)/100 = 10.12
For simplicity:
Gold coin = 10 Steel coins = 5 Silver coins.
Silver coin = 2 Steel coins.
That's all, folks! Any suggestions are welcome.
