In fact, the two text-analytic measures exhibit the highest correlations (within each data set) and are more substitutable for one another than for the network measures.
Supply growth in places like Phoenix will slow even as values rise.To put things another way: if it seemed as though housing in one city were perfectly substitutable for housing in another, then so long as supply were flexible somewhere we wouldn't expect wild price gyrations to come one after the other.
Such substitution costs may arise due to a variety of reasons: the cost of the reworking required on an item to make it substitutable for the other, loss of a customer's goodwill due to substitution, etc. Deterioration of physical goods in stock is a very realistic feature and there is a big need to consider it in the inventory modelling of substitutable items.
E.g., φ → Universal Instantiation: ∀αφ → φ, where φ is the result of uniformly substituting τ for the free occurrences of α in φ and τ is substitutable for α (i.e., no variable free in τ becomes bound by any quantifier in φ.
He assumes that workers of different types are not easily substitutable for each other, but that immigrants and natives within each category are.
There are very many forms including "lost," "ate," and "stole"—that can occur, as here, in constructions with a member of B and can also occur alone; for example, "lost" is substitutable for "stole the money," as "stole" is substitutable for either or for "lost his watch".
"Taking all the evidence in the round, we concluded that the availability of other media was not in itself sufficient to constrain the price of radio advertising and there was a significant proportion of campaigns for which radio advertising was not easily substitutable for other media".
And finally, for the theory to operate properly, these ideal conditions must be met: labour and capital must be fully employed so that increased productivity can be secured only at increased cost; capital and labour must be easily substitutable for each other; and the situation must be completely competitive.
Using arbitrarily selected letters to denote the form classes of English, "poor" may be a member of the form class A, "John" of the class B, "lost" of the class C, "his" of the class D, and "watch" of the class E. Because "poor John" is syntactically equivalent to (i.e., substitutable for) "John," it is to be classified as a member of A. So too, it can be assumed, is "his watch".
"Economically speaking, they're [one-bedroom residences] highly substitutable for rental stock," says Humphries.
