    This paper uses the EGARCH-M model to examine the impact of federal securities statutes on the mean and variance of total real U.S. stock market returns. In contrast to previous work, this study employs a longer time period, utilizes a broader array of stocks and examines the impact of eight major federal securities acts and their 573 amendments from 1933 through 2007. Despite the popular appeal of this legislation, our results indicate that these federal securities statutes and amendments have had no statistical impact on the mean or variance of total real stock returns over the past 75 years.securities regulations, SEC, GARCH, stock returns

    Measurements of the jet energy calibration and transverse momentum resolution in CMS are presented, performed with a data sample collected in proton-proton collisions at a centre-of-mass energy of 7TeV, corresponding to an integrated luminosity of 36pb-1. The transverse momentum balance in dijet and γ/Z+jets events is used to measure the jet energy response in the CMS detector, as well as the transverse momentum resolution. The results are presented for three different methods to reconstruct jets: a calorimeter-based approach, the "Jet-Plus-Track" approach, which improves the measurement of calorimeter jets by exploiting the associated tracks, and the "Particle Flow" approach, which attempts to reconstruct individually each particle in the event, prior to the jet clustering, based on information from all relevant subdetectors
