The main propositions which follow from definitions and axioms are listed here. These propositions are scientifically refutable, but are tested and not yet refuted by available evidence. Unlike axioms, these propositions would need constant testing and revision.
1. Predictions are possible in economics, but forecasts are generally not possible.
2. Net investment is the driver of economic growth. Money or credit is necessary but not sufficient for investment.
3. There is an optimal structure of aggregate demand for maximum economic growth.
4. There is a limit to the rate of sound economic growth determined by the optimal structure of aggregate demand.
5. Sound consumption or investment should be financed only from savings or capital accumulated from economic production.
6. Excessive debt above economic growth leads to wasteful spending, diminished economic growth and destruction of capital.
7. Consumption cannot increase indefinitely faster than income without economic collapse.
8. Government can impede economic growth. Recent data suggest a 10 percent increase in government expenditure to GDP leads to a 1.5 percent per annum average decrease in real GDP growth.
