Abstract

I study a static inspection game in which an inspector makes binary verdict based on evidence contaminated by an inspectee’s concealment effort. I characterize the equilibrium existence property under mild assumptions, showing that any equilibrium involves inspector’s use of a cutoff conviction strategy on the basis of evidence maturity. I identify several equilibrium effects, including a “pathological” one: as the inspector prioritizes on convicting the guilty rather than acquitting the innocent, the new equilibrium conviction threshold may relax, leading to a lower overall conviction rate. The results shed light on the optimal judicial mechanism design, and instrumentally justify the value of respecting liberty in authority’s terrorism prevention policy.

Keywords: Beyond a Reasonable Doubt, Inspection Game, Monotone Comparative Statics
