ACCELERATOR: The ratio between investment expenditures and the change in gross domestic product. This is based on the notion that business investment depends on the rate of growth of aggregate output. If the economy is expanding, in other words, then the business sector invests in more capital goods to produce the extra output needed. This accelerator effect modifies and magnifies the simply multiplier effect based on the induced consumption and the marginal propensity to consume.

Resource Quantity and Quality

Three ways to increase resource quantity.- Labor: Labor increases through (1) natural population growth, (2) immigration from other nations, and (3) more participation and fewer nonworkers.
- Capital: The key to getting more capital is investment, giving up satisfaction today to get capital tomorrow.
- Materials: The key to increasing their quantity is exploration. Exploration is best illustrated by digging or drilling into the Earth's crust in search of mineral or fossil fuel deposits.
Two ways to increase resource quality.- Education-The Quality of Labor: Education increases the quality of labor resources. Better educated workers are more productive workers.
- Education can be formal, sitting-in-a-classroom or informal, on-the-job-training experience. Both are valuable methods of increasing the quality labor.
- Technology-The Quality of Capital: Technology is the knowledge and information society as a whole possesses concerning the production of goods and services. Better technology enables more production.
- Technology concerns all aspects of production, but it is often seen as an improvement in the quality of capital.

ARC ELASTICITY The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.
