INJECTION: A non-consumption expenditure on gross domestic product, including investment expenditures, government purchases, and exports. Injections are combined with leakages in the injection-leakage model used to identify equilibrium aggregate output in Keynesian economics. The notion of injection is best viewed through the circular flow, in which investment expenditures, government purchases, and exports are "injected" into the main flow between output, factor payments, national income, and consumption.

Competition depends on the number of buyers and sellers.- More buyers creates more competition to acquire a good. Sellers don't have to sell a good below the going price with a lot of buyers willing and able to pay the market price.
Competition prevents buyers from forcing the price down to it's lowest level.- More sellers creates more competition to offer a good for sale. Buyers don't have to buy a good above the going price with a lot of sellers willing and able to sell at the market price.
Competition prevents sellers from forcing the price up to it's highest level.

SLOPE, NET EXPORTS LINE The negative slope of the net exports line is based on the marginal propensity to import (MPM). Because net exports are exports minus imports, the induced change in imports causes an opposite change in net exports. As such, the slope of the net exports line is negative, less than zero (but greater than negative one). The slope of the net exports line affects the slope of the aggregate expenditures line and thus also affects the magnitude of the multiplier process.
