The Oxford Economics Department has a large and vibrant group of economists working in diverse areas of microeconomic theory, including game theory, decision theory, behavioral economics, information economics and contract theory, auction theory, general equilibrium, and network economics.

There are three seminar series especially relevant to microeconomists: the Nuffield Economic Theory seminars (Friday afternoon), the Theory workshop (Tuesday lunchtime in even weeks during term), and the Learning, Games, and Networks Workshop (Tuesday lunchtime in odd weeks during term). In addition, there is a Student Research Workshop where graduate students present their work.
