SLOPE, INVESTMENT LINE: The positive slope of the investment line is also termed the marginal propensity to invest (MPI). This slope is greater than zero but less than one, reflecting induced investment. The slope of the investment line affects the slope of the aggregate expenditures line and thus also affects the magnitude of the multiplier process.

KINKED-DEMAND CURVE ANALYSIS An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.

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.
