"The more immediately a punishment is inflicted, the more ... useful it will be." Beccaria (1764)

In a new paper with Libor Dusek, we estimate the effects of a swift & delayed punishment on subsequent behavior in a straightforward context: speeding tickets

PS: In related work (same setting), we do NOT find clear evidence that higher #fines would amplify (specific) #deterrence effects – it’s about getting a ticket (or not), which makes drivers slow down... low/high fines seem 2nd order 👇

Given that (non-)compliance responses are small, the elasticity of revenues wrt fines is high (~0.9): a 100CZK increase in fines translates into ~60CZK higher revenues collected (within 15 days).

Might explain why "revenue motivated" authorities find fines attractive.

Christian Traxler @chtraxler.bsky.social · Jul 21

A 10% increase in the fine (= payment obligation) results in a 1pp drop in timely payments (timely = within 15 days after receiving a speeding ticket).

The semi-elasticity is close to what we found in earlier work in the context of TV license fees 👇

We explore (a) discontinuous increases in #speeding #fines at speed cutoffs (see figure) and (b) reforms affecting these discontinuities, to estimate the effect on non-compliance and revenues.

Our results indicate relatively small payment responses...
