Research Type Theoretical We study the existence of pure Nash equilibrium (PNE) for the mechanisms used in Internet services (e.g., online reviews and question-answering websites) to incentivize users to generate high-quality content. ... We prove the existence of PNE for some mechanisms and the non-existence for some other mechanisms. We also discuss how to find a PNE (if exists) through either a constructive way or a search algorithm.

Pseudocode Yes Algorithm 1 Algorithm to find a PNE of the original game from an induced local game Input: q = (q1, q2, qn) where q1 q2 qn; Output: x(n) = (x(n) 1 , x(n) 2 , , x(n) n ) 1: Calculate the yni i [n] with Eqn. (9). If none of yni is smaller than zero or larger than qi, x(n) yn; verify whether it can be extended to a PNE of the original game by Lemma 4; if so, return x(n). 2: for m 1 : n do 3: Calculate xnim i {m + 1, , n} with Eqn. (13). x(n) i qi i {1, , m}, x(n) i xnim i {m + 1, , n} if they are all feasible; 4: if x(n) is a local PNE (verified by Lemma 5) then 5: Verify whether x(n) can be extended to a PNE of the original game and return it if so; 6: end if 7: end for
