There is a slider allowing you to request your COO to set prices according to your wish. It ranges from Maximize Profit Margin to Maximize Market Share, or Balanced.

Maximize Profit Margin – Maximize profit margins by raising prices at the expense of market shares and capacity utilization rates

Maximize Market Share – Lower prices to gain market shares at the expense of profit margins.

Balanced – Balance market shares and profit margins and set prices sensibly.

You will also see the following policies: 

Freight Concern – If this is set to a high value, the AI executive will be more concerned with freight costs and tend to pick suppliers from closer distances.

Never sell products below costs – If this is enabled, the AI executive will never sell products below costs.

Look for better supplies – This determines whether the AI executive should look for better supplies in retail stores, factories and warehouses. (Better supplies mean products with higher overall ratings with no shortage of supply.) Note that the AI will NOT change the product type when it sources new supplies.

Low Supply Tolerance Level – If the value is set to low, the AI has lower tolerance of low supply and have greater tendency to look for new supply.

Look for better products to sell in retail stores – This determines whether the AI executive should look for better products to sell in retail stores only. (Better supplies mean products with higher overall ratings with no shortage of supply.) Note that the AI may change the product types at will.

The other policies are pretty straight-forward and self-explanatory.
