We consider the problem of randomly assigning n indivisible objects to n agents. Recent research introduced a promising mechanism, the probabilistic serial that has superior e¢ ciency properties than the most common real-life mechanism random priority. On the other hand, mechanisms based on Gale’s celebrated top trading cycles method have long dominated the indivisible goods literature (with the exception of the present context) thanks to their outstanding e¢ ciency features. We present an… CONTINUE READING
