CORE DEFINITION

If a country's currency (such as the US dollar) serves as the world's reserve currency, it must run trade deficits to supply the world with its currency (to provide liquidity); however, long-term trade deficits will cause the currency to depreciate, undermining its credibility as a reserve currency. This is an unsolvable deadlock. -

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Analysis of the fate of the dominant player. - This applies not only to countries but also to platform-based enterprises. A large platform (such as WeChat or Apple) that wants its ecosystem to thrive (by exporting liquidity/capabilities) must make concessions to developers, harming its own short-term profits; if it wants to maintain high profits, the ecosystem will wither. This is about the dilemma of 'being both the referee and a player'.

anchor

Anchor fast decisions

The inherent contradiction of the US dollar as a global reserve currency: meeting global liquidity requires the US to run persistent deficits, but deficits undermine confidence in the dollar. The mechanism is that liquidity supply and currency confidence cannot be achieved simultaneously.

In macroeconomics, total factor productivity (TFP), also known as total factor productivity or rate of technological progress, refers to all factors affecting output other than external inputs such as capital and labor. In simple terms, it is the improvement in the intrinsic strength of an economy, characterized by its ability to explain the factors of economic growth through a single simple figure.

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...
