# The exact law of large numbers via Fubini extension and characterization of insurable risks

@article{Sun2006TheEL, title={The exact law of large numbers via Fubini extension and characterization of insurable risks}, author={Y. Sun}, journal={J. Econ. Theory}, year={2006}, volume={126}, pages={31-69} }

A Fubini extension is formally introduced as a probability space that extends the usual product probability space and retains the Fubini property. Simple measure-theoretic methods are applied to this framework to obtain various versions of the exact law of large numbers and their converses for a continuum of random variables or stochastic processes. A model for a large economy with individual risks is developed; and insurable risks are characterized by essential pairwise independence. The usual… CONTINUE READING
