Investment Demand
Investment-demand concepts covering autonomous and induced investment, the accelerator model, inventory surprises, and circular-flow injections and leakages.
Autonomous investment, induced investment, saving propensities, investment demand, leakages, and life-cycle saving terms.
Investment Behavior, Saving, and Leakages explains why planned capital spending changes, how saving and consumption respond to income, and how withdrawals and additions interact in the circular flow of income.
Use Investment Demand and Leakages for investment demand, autonomous and induced investment, the accelerator model, inventory surprises, and circular-flow injections and leakages.
Use Saving, Consumption, and Capital Behavior for marginal propensities, life-cycle saving, knowledge capital, and underinvestment.
Keep model language separate from observed accounting data. An autonomous term is independent only within a stated model, induced investment need not respond immediately to output, and saving is a circular-flow leakage without being economically wasteful or permanently removed from finance.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
