Did Unilateral-No-Fault Divorce Laws Raise Divorce Rates?

Published · Contemporary Economic Policy · 2026

Between 1960 and 1980, thirty-five states let either spouse end a marriage without proving fault — the “no-fault revolution” critics still blame for the breakdown of the American family. Using stacked difference-in-differences with entropy balance, the paper finds the effect on divorce and marriage rates was neither enduring nor statistically significant. The data are right here — hover any year, pick your state.

Econsummation: The Rational Choice of Bedding Rituals

Working paper · Under review

Why did wedding guests once put the bride and groom to bed in front of everyone? Because marriage was a contract — and contracts need witnesses. A rational-choice account of Europe’s bedding rituals, from royal bedchambers to peasant weddings, and what they reveal about how societies verify their most important agreements.

Criminal Conversations

Working paper · Law & Economics

Before no-fault divorce, English courts put a price on adultery: “criminal conversation” suits let a husband sue his wife’s lover for damages. Ruinous verdicts, scandalous pamphlets, and courtroom caricature made these trials the tabloid spectacles of their age — and a revealing market in marital property rights. The prints below each carry their trial’s story.
