INDUCED INVESTMENT: Business investment expenditures that depend on income or production (especially national income or gross national product). An increase in national income triggers an increase in induced investment expenditures. Induced investment is graphically depicted as the slope of the investment line and is measured by the marginal propensity to invest. The induced relation between income and investment, as well as other induced expenditures, form the foundation of the multiplier effect triggered by changes in autonomous expenditures.

LONG-RUN TOTAL COST

The opportunity cost incurred by all of the factors of production used in the long run (when all inputs are variable) by a firm to produce a good or service, including wages paid to labor, rent paid for the land, interest paid to capital owners, and a normal profit earned by entrepreneurs. Unlike short-run total cost, long-run total cost cannot be separated into fixed cost and variable cost. In the long run, all inputs are variable, so all cost is variable.

It's time for another one of our frequent stops at Mr. Market Super Food Discount Store, this time to check out the story behind retail prices.

How do we know, like the name of the long-running game show, if "The Price is Right?" How are retail prices set and do they really tell us the value of a product?
