INTRODUCTION

English translation pending.

CORE DEFINITION

A welfare cost of inflation named for the wear on shoes from frequent trips to the bank. When inflation is high, holding money is expensive, so people make more frequent withdrawals, hold smaller balances, and spend time and resources converting cash into interest-bearing assets or foreign currency. The core claim is that inflation consumes real resources through changed behavior, not only through transfers of wealth. The qualification is that the cost is modest at low inflation and becomes significant only at high rates.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Friction Identification: Identify the recurring chores that inflation forces people to perform to protect value. - Use Cost Quantification: Estimate the time and resources spent on avoidance behavior rather than only on price changes. - Use Welfare Accounting: Include behavioral costs when evaluating the total burden of inflation.

Anchor fast decisions

Inflation taxes anyone who holds money, so the rational response is to hold less of it and visit the bank more often. Each trip consumes time, transaction fees, and attention that could have produced something else, which is a real resource cost rather than a transfer between parties. Because the burden scales with the inflation rate, the total loss stays small when prices are stable and grows sharply under rapid inflation.

Total Factor Productivity - TFP

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...
