Abstract: In resource accounting, shadow prices of natural resources and environmental effects should be used as the social marginal value of goods. Since it is difficult to measure shadow prices in practice, market prices are often used as proxies for shadow prices. A prerequisite for the use of these proxies is that there is an established relationship between size of the natural resource stock of interest and its market price. We have unique data sets on physical timber inventories in Finland and Sweden to analyze whether changes in stumpage prices have actually reflected changes in the stocks during the past seventy years. Cointegration and unit root tests are used for analyzing whether changes in market stumpage prices have reflected changes in physical timber stocks in Finland and Sweden during the past seventy years. The results indicate that no long-term equilibrium relationships exist between the timber prices and stocks.
