Real Wages

Definition

Real wages are the nominal wage divided by a price index, measuring the actual purchasing power of wage income. The formula is:

Real wage = Nominal wage ÷ Price index

If nominal wages rise 5% but consumer prices rise 4% over the same period, the real wage increase is roughly 1%. When inflation outpaces nominal wage growth, real wages fall.

Real wage = Nominal wage ÷ CPI × 100

Marx's Threefold Distinction

In Wage Labour and Capital (1849), Marx distinguished three dimensions of the wage:

1. Nominal wages: the money sum the worker receives from the capitalist (the money price of labour-power).
2. Real wages: the quantity of commodities that money can buy (the effective purchasing power).
3. Relative wages: the share of newly created value going to labour versus the share going to capital.

Marx argued that real wages can rise while relative wages fall. Productivity growth may let workers consume more goods, yet if labour's share of total output declines faster than capital's share, the worker's social position deteriorates. This is the core of the 'relative immiseration' thesis.

Real Wages in the South Korean Context

South Korea's real wage statistics are published monthly through the Ministry of Employment and Labor's Labour Force Survey at Establishments. Annual real wages for 2025 averaged 3.606 million won per month, a mere 0.9% increase from the previous year. With CPI rising to 2.6% in early 2026, real wages risk stagnation or decline if nominal wage growth fails to keep pace, a dynamic central to class analysis of the Korean labour market.
