MATURITY STAGE: The third stage in the product life cycle, characterized by flattening of sales and decreasing profit margins. Advertising and promotion are used to maintain market share and to prevent the erosion of sales and profits. During this stage, the initial decline of a product begins and many businesses try to "re-invent" their products to prevent the upcoming decline stage. Many times the company finds new uses for an existing product (baking soda as a deodorizer), totally new markets (foreign countries), or a way to enhance the existing product to make it better and to re-start the life cycle. The television has gone through at least two life cycles, first from black and white to color and then from color to high definition (HD) and plasma. Along the way there were enhancements such as remote control, VCRs to complement them, and cable to help with reception.

INJECTIONS-LEAKAGES MODEL

A macroeconomic model that balances non-consumption expenditures on production (injections) and non-consumption uses of income (leakages) that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. The injections-leakages model is based on the principles of Keynesian economics and provides an alternative to the standard aggregate expenditures (Keynesian cross) analysis. The three injections included in the model are investment expenditures, government purchases, and exports. The three leakages included in the model are saving, taxes, and imports. Three variations are the two-sector injections-leakages model (or saving-investment model), three-sector injections-leakages model, and four-sector injections-leakages model.

In his older years, Andrew Carnegie seldom carried money because he was offended by its sight and touch.
