According to the manual, Wisdom affects your Spell failure chance. However, that ability was swapped with Intelligence's influence over Magic Missile damage. As a result, Magic Missile damage is based on Wisdom.
Wisdom also affects the price to buy new Spells. Since you'll want plenty of Spells if you're going to be casting a lot, this makes Wisdom the most important spellcasting Stat. (Though Intelligence is very important as well for non-Clerics).
Wisdom also seems to have some effect on the sale price of Weapons and Armour, though only on the low end. High Wisdom seems to raise the minimum sale price, but Charisma takes over in this department pretty quickly.
