Learning from Law Enforcement This paper studies how punishment affects future compliance behavior and isolates deterrence effects mediated by learning. Using administrative data from speed cameras that capture the full driving hi

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 👇

(5/5)

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.

Higher Taxes, More Evasion? Evidence from Border Differentia This paper studies the evasion of TV license fees in Austria. We exploit border differentials to identify the effect of fees on evasion. Comparing municipalities at the low- and high-fee side of state

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 👇
ideas.repec.org/p/ces/ceswps...

(3/5)

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...

Fines, nonpayment, and revenues: evidence from speeding tickets Abstract. We estimate the effect of the level of fines on payment compliance and revenues collected from speeding tickets. Exploiting discontinuous increas

Result from randomized pairwise comparison of 4 alternative reform options. (N > 2,500)

Today we presented the new #MetallRente Study, a representative survey of 2,500 17-27yo young adults in GER. A striking result: instead of ↗️retirement age or ↘️pensions, kids prefer paying more to fund public #pension system. Details @hertieschool.bsky.social at www.hertie-school.org/en/news/rese...
