CORE DEFINITION

The hypothesis that whether the government finances its spending through debt (borrowing) or through taxes has the same effect on the economy. Because rational individuals know that today's borrowing implies future taxes, they will save rather than consume, thereby offsetting the effect of fiscal stimulus.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Provides an extreme perspective of rational expectations. Although in reality people are not fully rational, it reminds policymakers that public expectations can offset the intended effects of policies, and that there is no 'free lunch' from an intertemporal perspective.

anchor

Anchor fast decisions

Proposed by David Ricardo and formalized by Barro: when the government finances spending with debt rather than taxes, residents anticipate future tax increases and increase savings to offset, leaving aggregate demand unchanged.

Kondratiev Waves

In modern capitalist economies, the Kondratiev wave theory, also known as 'long waves', 'K-waves', or 'Kondratiev long waves', describes an economic cycle phenomenon with a period of approximately 50-60 years. The long wave is generally divided into two phases: the upward A-phase and the downward B-phase. This phenomenon can be explained by the technology life cycle. The name 'long wave' originates from the Soviet economist Nikolai Kondratiev, who proposed this view in his work 'The Major Economic Cycles' (1925) and other writings of the same period. Earlier, two Dutch economists, J. van Gelderen and Samuel de Wolff, had already deduced similar phenomena in 1913. Kondratiev's long wave theory first appeared in the book 'The World Economy and Its Fluctuations During and After the War' (completed in 1919-1920, published in 1922). Subsequently, he further developed the theory of long waves...
