On Two Kinds of Manipulation for School Choice Problems
نویسنده
چکیده
Many school districts in the US employ centralized clearing houses for the placement of students to public schools. A popular mechanism from two-sided matching theory, the Gale-Shapley studentoptimal stable mechanism, has recently replaced two de cient mechanisms that were in use in NYC and Boston. An important potential threat against any school choice mechanism is the tendency of schools to circumvent the procedure via two kinds of strategic manipulations introduced by Sönmez (1997, 1999): manipulation via underreporting capacities and manipulation via pre-arranged matches. This paper studies the extent of the vulnerability of a school choice mechanism, and in particular, that of the student-optimal stable mechanism, to the two manipulations, and identi es conditions under which they can be avoided.

On two classes of third order boundary value problems with finite spectrum
The spectral analysis of two classes of third order boundary value problems is investigated. For every positive integer $m$ we construct two classes of regular third order boundary value problems with at most $2m+1$ eigenvalues, counting multiplicity. These kinds of finite spectrum results are previously known only for even order boundary value problems.
