Environmental Economics Series ii 1 Introduction When natural capital is depleted without the machines, factories, buildings and simultaneous investment of a portion of infrastructure generate flows of goods and revenues into other assets, future generations services as the assets are used in the are left with fewer resources to produce production process. Similarly, stocks of goods and services. This premise is based natural capital, including petroleum deposits upon the writings of Sir John Hicks, Nobel that yield the flow of crude oil or forests that laureate in Economics, who noted yield the flow of cut timber, provide important economic benefits to their owners. The purpose of income calculations in This study examines natural capital depletion practical affairs is to give people an in Ecuador from 1971 to 1990, corresponding indication of the amount which they with an oil boom in the 1970s followed by can consume without impoverishing economic stagnation in the 1980s.

While revenues derived from such as purchases of goods and services, natural resource sales have the potential to payments to wage and profit earners, import finance investments in industrial capacity, payments and export revenues for goods and infrastructure, and human capital formation, services.
