We study path-independent choice rules applied to a matching context. We use a classic
representation of these choice rules to introduce a powerful technique for matching theory …

It is shown that a matching market with contracts can be embedded into a matching market
with salaries under weaker conditions than substitutability of contracts. In particular, the …

For combinatorial choice problems, I show that the Irrelevance of Rejected Items condition is
equivalent to the Weak Axiom of Revealed Preference (WARP), and is necessary and …

In a two-sided matching context we show how we can predict stable matchings by
considering only one side's preferences and the mutually acceptable pairs of agents. Our …

This paper presents weakened notions of corewise stability and setwise stability for
matching markets where agents have substitutable choice functions. We introduce the …

In a school choice context we show that considering only schools' priorities and the set of
