We investigate the implications of egalitarian equivalence (Pazner and Schmeidler in Q J Econ 92:671–687, <CitationRef CitationID="CR31">1978</CitationRef>) together with queue efficiency and strategyproofness in the context of queueing problems. We completely characterize the class of mechanisms satisfying the three requirements. Though...</citationref>

We consider the problem of regulating a monopolist with unknown costs when the regulator has limited funds. The optimal regulatory mechanism satisfies four properties. The first property is bunching at the top, that is the more efficient types produce the same quantity irrespective of their...

A well-known result in incentive theory is that for a very broad class of decision problems, there is no mechanism which achieves truth-telling in dominant strategies, efficiency and budget balancedness (or first best implementability). On the contrary, Mitra and Sen (1998), prove that linear...
