SUBSTITUTING COMPLEMENTS [PDF]
Journal of Competition Law & Economics, 2006 The presence of multiple sellers in the provision of (nonsubstitutable) complementary goods leads to outcomes that are worse than those generated by a monopoly (with a vertically integrated production of complements), a problem known in the economic literature as complementary oligopoly and recently popularized in the legal literature as the tragedy of

On the Construction of Substitutes [PDF]
Mathematics of Operations Research, 2018 Gross substitutability is a central concept in economics and is connected to important notions in discrete convex analysis, number theory, and the analysis of greedy algorithms in computer science. Many different characterizations are known for this class, but providing a constructive description remains a major open problem.

On testing substitutability [PDF]
Information Processing Letters, 2018 The papers~\cite{hatfimmokomi11} and~\cite{azizbrilharr13} propose algorithms for testing whether the choice function induced by a (strict) preference list of length $N$ over a universe $U$ is substitutable. The running time of these algorithms is $O(|U|^3\cdot N^3)$, respectively $O(|U|^2\cdot N^3)$.

Substituting a Substitute Currency: The Case of Estonia [PDF]
SSRN Electronic Journal, 2001 This study evaluates substitution of foreign currency balances in Estonia, a transition economy neighbouring countries participating in EMU. The focus is on substitution between dollar and euro balances in the three basic functions of money - unit of account, store of value and means of payment.

THE SUBSTITUTABILITY OF REINFORCERS [PDF]
Journal of the Experimental Analysis of Behavior, 1993 Substitutability is a construct borrowed from microeconomics that describes a continuum of possible interactions among the reinforcers in a given situation. Highly substitutable reinforcers, which occupy one end of the continuum, are readily traded for each other due to their functional similarity.

Journal of Symbolic ComputationLet $K$ be a field and $P=K[x_1,\dots,x_n]$. The technique of elimination by substitution is based on discovering a coherently $Z=(z_1,\dots,z_s)$-separating tuple of polynomials $(f_1,\dots,f_s)$ in an ideal $I$, i.e., on finding polynomials such that $f_i = z_i - h_i$ with $h_i \in K[X \setminus Z]$.
