Leontief’s input-output analysis revolutionized economic modeling by providing a systematic way to examine the interdependencies between industries. It allowed economists to predict the effects of changes in one part of the economy on the rest of the system. This method is widely used in economic forecasting, planning, and policy analysis.

Leontief applied input-output analysis to environmental issues, pioneering the field of environmental economics. His work helped to quantify the economic impact of environmental policies and the relationship between economic activity and environmental degradation.

Leontief paradox

In international trade, Leontief is also known for the Leontief paradox, which challenged the Heckscher-Ohlin theory. His empirical study showed that the United States, a capital-abundant country, exported more labor-intensive goods and imported more capital-intensive goods, contrary to expectations. This paradox spurred further research and revisions of trade theories.
