Moderating Variables (MV)Moderating Variables (MV)
• The introduction of a four-day week (IV) will lead to higher productivity (DV), especially among younger workers (MV)
• The switch to commission from a salary compensation system (IV) will lead to increased sales (DV) per worker, especially more experienced workers (MV).
• The loss of mining jobs (IV) leads to acceptance of higher-risk behaviors to earn a family-supporting income (DV) – particularly among those with a limited education (MV).

• With new customers (EV-control), a switch to commission from a salary compensation system (IV) will lead to increased sales productivity (DV) per worker, especially among younger workers (MV).
• Among residents with less than a high school education (EV-control), the loss of jobs (IV) leads to high-risk behaviors (DV), especially due to the proximity of the firing range (MV).

Intervening Variables (IVV)Intervening Variables (IVV)
• The switch to a commission compensation system (IV) will lead to higher sales (DV) by increasing overall compensation (IVV).
• A promotion campaign (IV) will increase savings activity (DV), especially when free prizes are offered (MV), but chiefly among smaller savers (EV-control). The results come from enhancing the motivation to save (IVV).
