The Oxford Handbook of Analytical Sociology is a foundational reference work edited by Peter Hedström and Peter Bearman, published by Oxford University Press in 2009. It is considered a core text for the field of analytical sociology.
Hedström became director of the Institute for Futures Studies in Stockholm in 2011 after leaving Nuffield College, Oxford. In 2014 he founded the Institute for Analytical Sociology at Linköping University in Sweden.
Hedström served as editor of Acta Sociologica and as associate editor of the American Journal of Sociology, the Annual Review of Sociology, and Rationality and Society. His paper on causal mechanisms, co-authored with Petri Ylikoski, appeared in the Annual Review of Sociology, volume 36.
