A ceteris paribus assumption is often key to scientific inquiry, because scientists seek to eliminate factors that perturb a relation of interest. [3] Thus epidemiologists , for example, may seek to control independent variables as factors that may influence dependent variables —the outcomes of interest. [ 4 ]
In general equilibrium analysis, on the other hand, the prices and quantities of all markets in the economy are considered simultaneously, including feedback effects from one to another, though the assumption of ceteris paribus is maintained with respect to such things as constancy of tastes and technology.
Part of the reason one input is altered ceteris paribus, is the idea of disposability of inputs. [25] With this assumption, essentially that some inputs are above the efficient level. Meaning, they can decrease without perceivable impact on output, after the manner of excessive fertiliser on a field.
The only assumption is that the environment follows some unknown but computable probability distribution. This theory is a mathematical formalization of Occam's razor. [23] [24] [25] Another technical approach to Occam's razor is ontological parsimony. [26] Parsimony means spareness and is also referred to as the Rule of Simplicity.
The relationship between price and quantity demanded holds true so long as it is complied with the ceteris paribus condition "all else remain equal" quantity demanded varies inversely with price when income and the prices of other goods remain constant. [3] If all else are not held equal, the law of demand may not necessarily hold. [4]
ceteris paribus "other things being equal" Commonly used in economics, ceteris paribus allows for supply and demand models to reflect specific variables. If one assumes that the only thing changing is, say, the price of wheat, then demand and supply will both be affected appropriately.
A new study found that omega-3 slowed biological aging by up to four months, with vitamin D and strength training boosting the effects: A neurologist explains.
The reason for this is that these logics describe defeasible reasoning, and conditionals that appear in real-world contexts typically allow for exceptions, default assumptions, ceteris paribus conditions, or just simple uncertainty. An example, derived from Ernest W. Adams, [3] If Jones wins the election, Smith will retire after the election.
