We study a setting in which a mechanism designer must choose the appropriate social alternative depending on the state of nature. We study the problem of optimal design and demonstrate that a mechanism that allocates the social optimum and assigns payments equal to the posterior expected utility...

I study a central authority’s ability to commit to a publicly announced mechanism in a one-to-one agent-object matching model. The authority announces a strategy-proof mechanism and then privately selects a mechanism to initiate a matching. An agent’s observation in form of the final...

We investigate how an informed designer maximizes her objective when facinga player whose payoff depends on both the designer's private information andon an unknown state within the classical quasilinear environment. Thedesigner can disclose arbitrary information about the state via...

We argue that contemporary stock market designs are, due to traders' inability to fully express their preferences over the execution times of their orders, prone to latency arbitrage. In turn, we propose a new order type which allows traders to specify the time at which their orders are executed...

Information plays a crucial role in mechanism design problems. A potential complication is that buyers may be inattentive, and so their information may endogenously and flexibly depend on the offered mechanism. I show that it is without loss of generality to consider contour mechanisms, which...

Nowadays, rating systems play a crucial role in the attraction of customers to different services. However, as it is difficult to detect a fake rating, fraudulent users can potentially unfairly impact the rating's aggregated score. This fraudulent behavior can negatively affect customers and...
