Ten years after publishing our first special issue in the field of contest theory in Economic Theory, the research field has experienced rapid development and shows a tremendous research dynamic. Some of these developments are reported in this Special Issue. The articles collected in this volume are a selection of papers presented at a workshop on "Current Frontiers in the Theory of Contests," held in Munich at the Max Planck Institute for Tax Law and Public Finance in May of 2016. The workshop consisted of eleven presentations, over a period of two days. Seven of the papers presented appear in the current issue, each having gone through anonymous review in the regular editorial process.In the lead article, Ewerhart (2022) reexamines the (first-price) chopstick auction of Szentes and Rosenthal (2003a, b). The chopstick auction describes a problem in which three identical items are auctioned at the same time, but the winner only benefits from these items if he buys two of them. For example, if a total of three "chopsticks" are auctioned, the willingness to pay for a single chopstick is determined by whether the player wins exactly one more chopstick. If he wins zero other chopsticks or two others, then the additional value of the one chopstick is zero. The intriguing thing about this problem is that the well-known discontinuity of the winning probabilities in the all-pay auction is now compounded by another discontinuity that emerges from the outcomes across the auctions of the single chopsticks. Ewerhart constructs a new equilibrium, referred to as a self-similar equilibrium (SSE), which allows an intuitive characterization. The equilibrium is constructed using an approach due to Sion and B Dan Kovenock
