We discuss examples of complex systems composed of many interacting subsystems. We focus on those systems displaying nontrivial long-range correlations. These include the one-dimensional sequence of base pairs in DNA, the sequence of flight times of the large seabird Wandering Albatross, and the...

We illustrate the general principle that in biophysics, econophysics and possibly even city growth, the conceptual framework provided by scaling and universality may be of use in making sense of complex statistical data. Specifically, we discuss recent work on DNA sequences, heartbeat intervals,...

Most of the market microstructure literature has focused on the liquidity of individual securities, whereas most of the asset pricing literature has focused on the association between systematic risk and return. We document the presence of a systematic, time-varying component of liquidity. At...

Previous work on bioprospecting has suggested that the potential market returns to genetic resource conservation are likely to be inconsequential. This article shows that when the buyers of genetic resource options are also competitors in patent races, sellers can extract all the surplus...
