===Economy===
Economy fluctuation causes the currency to gain and lose value. For every 5 points above the normal Economy value, currency gains 1% in value; for every 5 points below, currency loses 1% of its value.

In addition, if a city's Economy drops to 0 or below, the currency drops 1% in value for each point of Economy below 0.

To determine Economy's effect on the price of a given item, divide the item's price by the currency value as a percentage. This will result in the city's price for the item.
