Who's fault is it? I am not talking about going over time for 5-10 mins. I am talking about going over time for more than 20 mins! The speaker should respect his audience, so should the seminar chair. When it's one-hour seminar, the speaker should leave 15 mins for the audience. If you cannot do that, then at least do not go beyond one hour...
Do buyers and sellers behave similarly in a limit order book? A high-frequency data examination of the Finnish stock exchange Kaj Hedvall a , , , Jonas Niemeyer b and Gunnar Rosenqvist a a Swedish School of Economics and Business Administration, P.O. Box 479, 00101, Helsinki, Finland b Stockholm School of Economics, Stockholm, Sweden Available online 10 June 1998. Abstract The symmetry of an electronic limit order book is studied using high-frequency data. Is the order flow generated by buyers of the same structure as the one by sellers or would factors such as short selling restrictions and information trading result in asymmetries in the order flow? A model expressing the symmetry of a limit order book is developed and tested within a log-linear Poisson regression framework. Although the orderflow was found to be quite symmetric in general, clear asymmetries were identified for various trade categories suggesting differences between the order submission of buyers and sellers using a limit order book.
