Group 1 - Inflation leads to early consumption, creating an "inflation spiral" where rising prices stimulate further consumption [3][5] - In a deflationary environment, delaying consumption is beneficial, resulting in a "deflation spiral" that exacerbates deflation [4][13] - Borrowing is advantageous in inflationary conditions, as the real value of debt decreases, encouraging more borrowing and increasing money circulation [10][11] Group 2 - The impact of inflation and deflation on housing prices illustrates the risks associated with borrowing; a significant drop in property value can lead to substantial losses [11][12] - CPI statistics may exaggerate inflation during periods of consumption upgrades, while deflation may not be fully captured due to quality degradation in products [16][20] - Technological advancements generally exert a deflationary effect, while stagnation in technology can lead to inflationary pressures [21][30] Group 3 - The "Amazon effect" in the U.S. retail sector demonstrates how e-commerce can suppress inflation through lower prices and increased efficiency [27] - China's manufacturing advantages stem from a combination of efficient supply chains, infrastructure, and cost control, contributing to a deflationary environment [28][29] - Economic balance is maintained through the interplay of financial mechanisms creating inflation and technological advancements fostering deflation [34][35]
