Homeowners? Repeat-Sale Gains, Dual Agency and Repeated Use of the Same Agent

Previous studies of dual agency, where one agent serves both buyer and seller in a transaction, use hedonic models. Repeat-sale methods can test for the price effect of accepting dual agency. Dual agency does not show convincing effects on expected gain, which would occur if there was a systematic bias, or on heteroscedasticity, which would occur if there are large effects that are rare. Earlier researchers could not test for the effect of an owner picking a listing agent who was the earlier selling agent. Consistently positive mean abnormal price gains come from this choice, as well as signi?cant heteroscedasticity.

Empirical Regularities in the Market for Real Estate Research Output

This study examines whether any regularity exists in the publication pattern among real estate researchers. Identifying an empirical regularity in research output is useful since it helps assess both the likelihood of multiple publications and the degree of author concentration among different journals. The empirical results reveal that a strong bibliometric regularity exists in the real estate literature: the number of authors publishing n papers is approximately 1/n^c of those publishing one paper. It is shown that the real estate literature conforms very well to the model with c=2.446 if data are taken from a large collection of journals. When applied to individual journals, the result shows that values of c range from 2.321 to 3.835.

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
