When one switches from the obsolete subjective-behavioral approach to the correct objective-structural Paradigm then one gets this Employment Law Wikimedia AXEC07 for the business sector as a whole under the condition of product market clearing.
• investment expenditures I
• an increasing expenditure ratio ρE (i.e., the average propensity to consume),
• an increasing wage rate W,
