Advantages of the Market Price Method
¥ The market price method reflects an individual's willingness to pay for costs and benefits of goods that are bought and sold in markets, such as fish, timber, or fuel wood.  Thus, peopleÕs values are likely to be well-defined.
¥ Price, quantity and cost data are relatively easy to obtain for established markets.
¥ The method uses observed data of actual consumer preferences.
¥ The method uses standard, accepted economic techniques.

Issues and Limitations of the Market Price Method
¥ Market data may only be available for a limited number of goods and services provided by an ecological resource and may not reflect the value of all productive uses of a resource.
¥ The true economic value of goods or services may not be fully reflected in market transactions, due to market imperfections and/or policy failures. 
¥ Seasonal variations and other effects on price must be considered.
¥The method cannot be easily used to measure the value of larger scale changes that are likely to affect the supply of or demand for a good or service.
¥Usually, the market price method does not deduct the market value of other resources used to bring ecosystem products to market, and thus may overstate benefits.
