Knowledge Capital
Knowledge capital is accumulated know-how, research, data, skills, and intellectual property that can raise productivity and value.
Saving, consumption, and capital-behavior terms used in macro models and financing constraints.
Saving, Consumption, and Capital Behavior covers capital formation, investment spending, saving behavior, productivity, depreciation, obsolescence, and public investment funds used in finance and macro analysis.
Use these pages when productive capacity, replacement investment, capital intensity, productivity, or investment demand changes growth, margins, valuation, or public-sector investment assumptions. It sits inside Investment Behavior, Saving, and Leakages, so readers can move up when the broader economics context matters.
Use the table below to choose the narrower economics branch before applying a term to a model, credit view, market interpretation, policy conclusion, or risk review. Move into the term page when the evidence source, calculation, institution, market convention, or risk exposure matters.
| Area | Use it for |
|---|---|
| Knowledge Capital | Knowledge capital is accumulated know-how, research, data, skills, and intellectual property that can raise productivity and value. |
| Life-Cycle Hypothesis | The life-cycle hypothesis explains saving and consumption as households smooth spending over working years and retirement. |
| Marginal Propensity to Consume | Marginal propensity to consume measures the share of an additional dollar of income that households spend instead of save. |
| Marginal Propensity to Invest | Share of additional income or output directed toward investment rather than consumption or saving. |
| Marginal Propensity to Save | Marginal propensity to save measures the share of an additional dollar of income that households save rather than spend. |

Capital and productivity explanations are educational and do not recommend a project, security, fund, or allocation.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
