This is the consequence of using aggregate data to measure a variable that is only meaningful in physical terms. Indeed, aggregate unit labour costs are not just a weighted average of the firm’s unit labour costs. We have shown that aggregate unit labour costs can be interpreted as the product of the share of labour in output multiplied by the price deflator. The increase in aggregate unit labour costs observed across the Eurozone is the result of the increase in the second component, the deflator. In fact, except in Greece, labour shares have either remained stable since 1980, or declined.(...)"
