Reference excerpt

Kathryn Graddy is a professor of economics and the dean of Brandeis International Business School at Brandeis University. She is the Fred and Rita Richman Distinguished Professor in Economics at Brandeis University. Her research interests include the economics of art, culture, and industrial organization.

Career Graddy received a BS in mathematics and a BA in Russian language from Tulane University, an MBA from Columbia University, and a PhD in economics from Princeton University. Prior to her position at the University of Oxford, she was appointed as an assistant professor of economics at the London Business School. Afterwards, she was a research fellow at Jesus College and then at Exeter College. After leaving Oxford, Graddy joined Brandeis University in 2007. She chaired the university's department of economics from 2011 to 2014 and directed the PhD program at Brandeis International Business School (IBS) from 2015 to 2016. In 2013, she was made the Fred and Rita Richman Distinguished Professor in Economics. She was named senior associate dean of IBS in 2016, a position she held until she became dean in 2018.

Research

Graddy's research interests include the economics of art, culture, and industrial organization. She has been widely quoted in the media as an expert on art auctions and investment in art. Graddy spent a month shadowing a trader at the Fulton Fish Market to analyze competition within fish markets, and published the results in 2006 study finding that traders appeared to charge different prices to different ethnic groups and that perfect competition at the market was not apparent. In a 2017 paper co-authored with Princeton University economist Carl Lieberman, the two economists concluded that "artists, in the year following the death of a friend or relative, are on average less creative than at other times of their lives." The results were based on an analysis of thirty-three French Impressionist painters and fifteen American artists born between 1910 and 1920. The results, which were featured in the popular press, followed an earlier working paper by Graddy that found that visual artists' creative output suffered during periods of bereavement.

Worked examples

Example 1 — a first encounter with Kathryn Graddy

Start with the simplest possible case. Write down what Kathryn Graddy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kathryn Graddy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kathryn Graddy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kathryn Graddy

In research: Kathryn Graddy appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kathryn Graddy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kathryn Graddy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academics of London Business School, Brandeis University faculty, Columbia Business School alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Kathryn Graddy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
