Audio/Video: Fault in Contract Law

In September, Frank and Bernice J. Greenberg Professor of Law Omri Ben-Shahar and Fischel-Neil Visiting Professor of Law Ariel Porat organized a conference intended to reevaluate the role of fault in contract law. Speakers included Chicago faculty Saul Levmore, Eric Posner, Richard Epstein and Judge Richard Posner, along with experts in contract law from around the world. Subscribers to our Faculty Podcast may have already heard Judge Posner’s “Let Us Never Blame a Contract Breaker,” and audio and video of the entire conference is now available on the conference website. … [Here is] Professor Ben-Shahar’s introduction to the conference …

The papers from the conference will be published in the June 2009 issue of the Michigan Law Review, and an expanded volume collection will be published later by Cambridge University Press. In the meantime, the abstracts are on the Michigan Law Review site, and here are some of the drafts I’ve been able to find online, mostly (though not exclusively) from SSRN:
