Some reflections on the economics of prosecutors: Mandatory vs. selective prosecution

Mandatory prosecution is inefficient according to legal economists. We argue that when prosecutors are fairly insulated from their performance or are highly risk-averse mandatory prosecution is better than selective prosecution. This result has important implications for comparative law. We use our findings to provide a positive explanation for the stylized fact that mandatory prosecution generally prevails in civil law jurisdictions whereas selective prosecution is typical of common law jurisdictions.Prosecutors Mandatory prosecution Selective prosecution Civil law Common law
