LRMC CURVE: The common abbreviation for the long-run marginal cost curve, which is the graphical representation of the relationship between long-run marginal cost and the quantity of output produced. Like other marginal curves, the long-run marginal cost curve follows the average-marginal rule relative to the long-run average cost curve. In all outward appearance, the long-run marginal cost curve looks very much like the short-run marginal cost, that is, it is U-shaped. However, the U-shape is attributable to returns to scale rather than increasing and decreasing marginal returns.

MARGINAL PROPENSITY TO INVEST The change in business investment expenditures induced by a change in income or production (national income or gross domestic product). The marginal propensity to invest (abbreviated MPI) is another term for the slope of the investment line and is calculated as the change in investment divided by the change in income or production. The MPI plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to the multiplier process. A related marginal measure is the marginal propensity to consume.

Collecting WELFAREI know word travels quickly among pedestrians of Shady Valley, but perhaps you haven't heard the latest. Pollyana Pumpernickel, the proprietor of Pollyana's Pet Palace, is no longer a pet proprietor. She's fallen on hard times, and fallen quite hard. Her husband of twelve years, Paul Pumpernickel has dumped her and their three young children to pursue insurance alternatives with Tricia Comer -- Smilin' Ted's sister and business partner in the All Comers Insurance Agency. Pollyana is distraught, to say the least. Paul Pumpernickel had been the dutiful househusband and caring father in his marriage partnership with Pollyana, but those duties fell onto the heavily burdened shoulders of Pollyana. The burden was too much. Pollyana's Pet Palace plundered into oblivion, leaving Pollyana penniless and jobless. Her only alternative was our government's public assistance program -- what you and I know as welfare. She's not pleased with her current social status, and neither, apparently is Winston Smythe Kennsington III, who ridicules poor Pollyana at every opportunity.

[What's This?]
Today, you are likely to spend a great deal of time going from convenience store to convenience store hoping to buy either a weathervane with a cow on top or a box of multi-colored, plastic paper clips. Be on the lookout for telephone calls from former employers.
