The contrast of following pairs of terms are as mentioned:
- Dynamic efficiency balance present and future uses of a
depletable resource by maximizing the present value of the net
benefits derived from its use; this implies a particular allocation
of the resource across time. It allows an efficient evaluate
resources allocation across Time period It is all most
impossible to implement because it requires to know the preferences
of the future generation. A more operational version of
sustainablity criterion. “Hartwick’s Rule”. (Weak Sustainability) A
constant level of consumption can be maintained perpetually from an
environmental endowment if all scarcity rent is invested in
capital. If all scarcity rent is invested in capital, the value of
the total capital stock will not decline. If the principal or the
value of total capital is declining,
- the criteria pollutants are the harmful natural pollutants
which are in the form of carbon monoxide, lead, nitrogen dioxide,
ozone, particulate matter, and sulfur dioxide.EPA reports that
releases of all criteria air pollutants except nitrogen oxides have
been in decline since the passage of the 1970 CAA. Overall air
quality has improved significantly nationwide since the 1980s.
These improvements, however, have not eliminated air quality
problems, and major efforts to control pollution sources are still
required to ensure everyone breathes air that meets CAA
standards.Population growth and economic expansion increasingly are
stressing water resources in southern Alberta, Canada. Adopting
market mechanisms may improve water use efficiency. Utilizing a
novel network model of an entire river basin, we quantify the
short-run efficiency gains (over one growing season) from
reallocating surface water. Employing a standard welfare maximizing
objective, and observing essential institutional and hydrologic
structures, we find the relative efficiency gains from introducing
market pricing to be under 3% for a year of surplus water flows,
about 6% for a mean flow year, and more than 15% for a drought flow
year. Although such gains exclude the costs of the current water
allocation policy, as well as those of moving to market pricing,
results tend to support the present cautious approach by the
Alberta government to modify the mechanisms for allocating surface
water.
- In forestry rotation analysis, economically optimum rotation
can be defined as “that age of rotation when the harvest of
stumpage will generate the maximum revenue or economic yield”. In
an economically optimum forest rotation analysis, the decision
regarding optimum rotation age is undertake by calculating the
maximum net present value.
- The discount rate is a financial term that can have two
meanings. In banking, it is the interest rate the Federal Reserve
charges banks for overnight loans. Despite its name, the discount
rate is not reduced. In fact, it’s higher than market rates, since
these loans are meant to be only backup sources of funding. During
major financial crises, though, the Fed may lower the discount rate
– and lengthen the loan time. In investing and accounting, the
discount rate is the rate of return used to figure what future cash
flows are worth today.
