I'm Matthew Wildrick Thomas, an Economics PhD candidate at Northwestern University. I am currently interested in applied microeconomic theory including information in financial markets, contests, and lobbying. This page is here to share my academic and non-academic projects.

What happens when the prize in an all-pay auction depends on players' bids?

PDFWhen opposing parties compete for a prize, the sunk effort players exert during the conflict can affect the value of the winner’s reward. These *spillovers* can have substantial influence on the equilibrium behavior of participants in applications such as lobbying, warfare, labor tournaments, marketing, and R&D races. To understand this influence, we study a general class of asymmetric, two-player all-pay contests where we allow for spillovers in each player’s reward. The link between participants’ efforts and rewards yields novel effects – in particular, players with higher costs and lower values than their opponent sometimes extract larger payoffs.

Can you design a symmetric contest such that one player is favored?

PDF SlidesA contest designer may wish to disadvantage a stronger player to improve competitiveness. We show this can be done in all-pay auctions such that the game is fair (i.e. symmetric) ex-ante. Yet, the stronger player is endogenously offered a lower prize in expectation. Thus, discrimination is *covert*.
