It is consistent with the behavior of the household followed by rule of demand.
However, none of the above justifies (or is reason enough to deny) the simple rule of demand and supply, which makes it clear that the conscious decision to consume animal products contributes to the demand for more animals to be bred and killed.
1Hicks (1932) gives the classic presentation of Marshall's rules of derived demand.
The resulting general equilibrium model has much in common with derivations of Marshall's rules of derived demand.
The general equilibrium framework reveals that the effect of immigration on the mean wage depends on the parameters that Marshall first identified in his famous rules of derived demand (i.e., the elasticity of substitution between labor and capital, the supply elasticity of capital, the elasticity of product demand, and labor's share of income).
Symbols are mathematical entities, not abbreviations, and as such do not have an appended period/full stop, unless the rules of grammar demand one for another reason, such as denoting the end of a sentence.
If practices outlined in this story are within the rules, then the solution is simple: Change the rules instead of demanding more taxes.
When the undercover authors offered to pay a premium to flout the rules, the rate of demand for identity documents fell precipitously.
This latter condition, of course, has a familiar ring in labor economics—as it happens to be identical to the condition that validates Marshall's second rule of derived demand: An increase in labor's share of income leads to more elastic demand "only when the consumer can substitute more easily than the entrepreneur" (Hicks, 1932, p. 246).
It's called the rule of induced demand, and it's like trying to solve overeating by loosening your belt.
