SERVICES, CONSUMPTION: Personal consumption expenditures on activities that provide direct satisfaction of wants and needs without the production of tangible goods. Common examples are information, entertainment, and education. This is one of three categories of personal consumption expenditures in the National Income and Product Accounts maintained by the Bureau of Economic Analysis. The other two are durable goods (see durable goods, consumption) and nondurable goods (see nondurable goods, consumption). Services are about 60% of personal consumption expenditures and 40% of gross domestic product.

KEYNESIAN MODEL A macroeconomic model based on the principles of Keynesian economics that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. This model identifies equilibrium aggregate production and income as the intersection of the aggregate expenditures line and the 45-degree line. The Keynesian model comes in three basic variations designated by the number of macroeconomic sectors included--two-sector, three-sector, and four sector. The Keynesian model is also commonly presented in the form of injections and leakages in addition to the standard aggregate expenditures format. This model is used to analyze several important topics and issues, including multipliers, business cycles, fiscal policy, and monetary policy.
