RISK AVERSE: A person who values a certain income more than an equal amount of income that involves risk or uncertainty. To illustrate, let's say that you're given two options--(A) a guaranteed $1,000 or (b) a 50-50 chance of getting either $500 or $1,500. If you chose option A, then you're risk averse. Both options give you the same "expected" values. In other words, if you select option B a few hundred times, then your average amount over those few hundred times is $1,000.

GOVERNMENT PURCHASES LINE

A graphical depiction of the relation between government purchases by the government sector and the economy's aggregate level of income or production. This relation plays a key role in the study of Keynesian economics. A government purchases line is characterized by vertical intercept, which indicates autonomous government purchases, and slope, which is the marginal propensity for government purchases and indicates induced government purchases. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the government purchases line onto the consumption line, as well as investment expenditures and net exports.
