There is substantial commonality of subject matter across diverse
academic areas therefore one should look outside one's own field for
fresh ideas.  For example, let's not forget the contributions of
economists to time series analysis.   I believe the first stochastic
convergence proof for LS estimation of  AR parameters was published in
Economerica in 1943.
