You have a point about all the information you provided OP, and many businesses have collapsed due to the business owner knowing all this pricing strategy while some business owners that understand the pricing strategy don't know when to truly apply it to boost their business.
Having said that, when start a new business I believe using all the 3 strategies will help and the best strategy I believe it good to use for a start is the competition based pricing.
More likely, these forms to pricing are associated to certain stage in production. While all the categories to pricing could be very useful to producers, when you are a retailer, you really don’t have much choice rather than to use the cost based pricing where you get your determine what it took to get and transport the product, add some amount for profit and sell it off. Producers are the once that concerns themselves with competitive and value based pricing since, you don’t get much in value when you are breaking in the market and when the product carries just fine, then you can talk about value.
