Contemporaneous inflation, [[pi].sub.t], depends upon expected future inflation, [[pi].sub.t+1.sup.e], and a real variable
measuring the intensity of resource utilization.
Fischer (1996) suggests that the reason the central banks of the world's industrialized economies have avidly pursued long-run price stability is because in the long run, inflation has distortionary effects that adversely impact a real variable
, or a group of real variables
, that people care about.
They cover functions of one real variable
from the perspectives of elementary properties of functions, limits, continuity, differentiation, integrals, and sequences and series.
Furthermore, the minutes of FOMC meetings (Board, Annual Reports) suggest that the FOMC does not use money as an indicator variable, but instead appears to use a real variable
, typically a growth gap or an output gap.
A mapping [??] : T [right arrow] [E.sup.1] is referred to as a fuzzy number-valued function of a real variable
P Natanson, Theory of Functions of a Real Variable
The most robust rules, subject to the least control error, involve targets that depend on the fewest weasel variables, where a "weasel variable" is any real variable
that can influence the short-run behavior of the target variable.
where u(x), is an analytic complex function of a real variable
[y.sub.1] = [x.sub.1] + [ix.sub.2], [y.sub.2] = [x.sub.3] + [ix.sub.4] are complex variables, [y.sub.3] = [x.sub.5] is real variable
, and i = ([square root of - 1]).
A real variable
such as employment and real economic growth are regression on other variables such as real money, real growth rate of government spending and growth rate of oil revenues and once the actual amount of money are regression on real economic growth rate, real growth rate of government spending and growth rate oil revenues.
Since both of the last two series evidently are uniformly and absolutely convergent with respect to the real variable
u, they can be integrated term by term, so that finally it easily follows
"The one real variable
is Democratic crossover," DeCluitt said, pointing to a busy race for sheriff that could draw local voters of every political stripe into the GOP primary.
