My primary research interest lies in the domain of Mechanism and Market Design. My contribution to mechanism design includes the analysis of fundamental questions of implementation. In particular, [2] shows that in standard social choice environments with private types Bayesian incentive compatibility (BIC) is equivalent to dominant strategy incentive compatibility (DIC). Subsequent papers ([6], [7]) extend this result to environments with correlated types and non-linear utilities. In conjunction with the BIC-DIC equivalence, [8] analyzes also a purely mathematical question when a projection of two convex closed sets coincides with the intersection of their images.

Another paper [3] develops a novel geometric approach to mechanism design that exploits classical results from convex analysis and majorization theory to provide a tractable analysis of generally complex resource and incentive constraints. A subsequent paper [4] extends the geometric approach to environments with interdependent values.

My work on market design focuses on the analysis of a signaling mechanism in two-sided matching markets. This endeavor shows that the introduction of private signals facilitates match formation for a wide range of environments ([1]). Nevertheless, there are instances when signaling precludes match formation ([5]).

I am also involved in projects related to the theory of networks ([9]) and optimal income taxation ([10]).
