help Wassily Leontief FAQ
How does Leontief input-output analysis work?
An input-output table records how one industry's output becomes another industry's input. The resulting matrix can estimate how a change in final demand for cars, for example, affects steel, electricity, transport, and other supplying industries.
What is the Leontief inverse?
The Leontief inverse is a matrix that captures both the direct and indirect production needed to satisfy final demand. It lets analysts move beyond the first supplier and calculate effects propagated through an entire network of industries.
What was the Leontief paradox?
Leontief found that United States exports appeared less capital-intensive than its import-competing production, contrary to a simple prediction of the Heckscher-Ohlin trade model. The result became known as the Leontief paradox and stimulated research on human capital, technology, and trade measurement.
Why did Wassily Leontief receive the 1973 Nobel Prize?
Leontief received the prize for developing input-output analysis and applying it to major economic problems. His framework influenced national accounting, industrial planning, environmental analysis, and regional economic modeling.
