It is shown that substitutive work, which can be defined as work of production equipment (capital stock) replacing the efforts of workers in production processes, can be considered as a measure of technical progress. The methods of estimation of substitutive work are discussed. The theoretical results are illustrated on the data for the US. economy.

In 1974, it was a live question whether the exhaustion of natural resources, such as oil, would necessarily lead to the decline of economic activity. Solow showed that constant levels of consumption could be sustained if there is sufficient substitutability between produced and natural factors of production. Hartwick then proved that underpinning this result is a saving rule—set investment in produced capital equal to the value of resource depletion at each point in time. A large literature has shown that a comprehensive measure of the change in real wealth—net saving—plays a central role in determining whether current well-being can be sustained. The current composition of wealth serves to define the policy challenges that countries face in achieving sustainable development. If substitution possibilities are limited between natural and other factors of production, as one might expect, then technical progress is a necessary complement to policies for sustainability.
