* This paper was inspired by a conversation Berman had with his great uncle Rafuel Grinspun, shortly after the latter migrated from the Soviet Union. We appreciate the helpful comments of Lawrence Katz, Kevin Lang, Shlomo Yitzhaki and seminar participants at Boston University, the Hebrew University, Maryland, Yale, Michigan, MIT and an NBER Labor Studies session.

Several groups have recently modeled evolutionary transitions from an ancestral allele to a beneficial allele separated by one or more intervening mutants. The beneficial allele can become fixed if a succession of intermediate mutants are fixed or alternatively if successive mutants arise while the previous intermediate mutant is still segregating. This latter process has been termed stochastic...

We reconsider the Moran model in continuous time with population size N, two allelic types, and selection. We introduce a new particle representation, which we call the labelled Moran model, and which has the same distribution of type frequencies as the original Moran model, provided the initial values are chosen appropriately. In the new model, individuals are labelled 1,2,…,N; neutral resampl...

The Moran model is a discrete-time birth and death Markov chain describing the evolution of the number of type 1 alleles in an haploid population with two alleles whose total size N is preserved during the course of evolution. Bias mechanisms such as mutations or selection can affect its neutral dynamics. For the ergodic Moran model with mutations, we get interested into the fixation probabilit...

The Moran collection, which has been catalogued over the last two years, has presented the archivist with a number of interesting problems, besides those normally associated with a collection of personal papers. The extensive collection' had been used by Professor Lovell for his biography of Lord Moran while it was still at the family homes and it was following an approach by the archivist of t...

helped to qualify this, because in order to win Moritz's favour it was not enough to claim special revelation; as other plausible obfuscation failed, one had to achieve some practical credibility. The quarrel between Andreas Libavius and Johannes Hartmann, the subject of a separate monograph by Moran, also assisted in the process. As Moritz's appointee to the first chair of Paracelsian chemistr...

To the world at large, Lord Moran was the doctor who looked after Winston Churchill, and who precipitated a storm ofcomment when he published an account of the illnesses ofhis recently dead patient in 1966.1 But Charles Moran contributed to his times, and to posterity, in several other roles. A few surviving soldiers of the First World War, in their great age, remember him as a doctor who looke...
