Search for ttˉt\bar{t} resonances in semileptonic final states in pp collisions at s\sqrt{s} = 8 TeV

A search for the production of new heavy resonances produced in proton-proton collisions at the CMS Experiment that decay into top quark pairs is presented. Data was recorded at a center of mass energy of 8 TeV and corresponds to an integrated luminosity of 19.6 fb$^{-1}$. Results are presented as a combination of two dedicated searches, the first optimized for kinematic threshold production of top quark pairs and the second optimized for a highly boosted regime. No excess is observed above the expected yield from SM processes. In the absence of any excess we set the following limits at 95% CL on the production of non-SM particles. Top color Z' bosons with relative widths of 1.2% and 10% are excluded for masses below 2.10 TeV and 2.68 TeV. Upper limits of 1.94 pb and 0.029 pb are set on the production cross section times branching fraction for narrow resonances with masses of 0.5 TeV and 2 TeV. Likewise, limits of 1.71 pb and 0.045 pb are set for wide resonances with masses of 0.5 TeV and 2 TeV. In addition, Kaluza-Klein excitations of a gluon with masses below 2.54 TeV in the Randall-Sundrum model are excluded and an upper limit of 0.101 pb is set for a resonance mass of 2 TeV.Comment: Presentation at the DPF 2013 Meeting of the American Physical Society Division of Particles and Fields, Santa Cruz, California, August 13-17, 201

Why Does No One Teach Undergraduate Macroeconomics Using the Dyanmic Stochastic General Equilibrium Model?

This paper argues that the reason that the DSGE model, which has proved so successful in convincing academic economists of its value, has made relatively few inroads into the undergraduate teaching sphere is that it fails to allow for the development of higher order educational objectives in students. The qualities which make it attractive to academics, such as the purity of its assumptions and its sound microeconomic basis, have little resonance with undergraduate students. Instead, the qualities of the neo-Keynesian model, such as its ability to incorporate 'real-world' institutional features and the ease with which it can be used to develop higher order skills and applications, prove much more attractive.macroeconomics, DSGE models, pedagogical approaches

Teaching Undergraduate Macroeconomics with the Taylor-Romer Model

This paper sets out a version of the Taylor-Romer model of short-run macroeconomic equilibrium which can be used for teaching undergraduate economics principles courses. The aim is to generate a model with the proven advantages of the IS-LM framework but with a more realistic description of central bank behaviour. The paper then provides a dynamic analysis of longer-term adjustment using a phase diagram but without the need for a formal mathematical derivation.

Some UK evidence on the Forward Looking IS Equation:

This paper seeks to demonstrate that a backward looking specification of the IS curve using UK data can encompass the forward looking model recently discussed by Kara and Nelson (2004). By relaxing the restriction that the interest rate and the inflation rate enter the IS curve with coefficients of equal magnitude but opposite sign, we obtain IS curve estimates which are empirically plausible and which encompass the rival specification.IS curve, forward looking, real interest rate.

Testing for cointegration using the Johansen approach: Are we using the correct critical values?

This paper presents Monte Carlo simulations for the Johansen cointegration test which indicate that the critical values applied in a number of econometrics software packages are inappropriate. This is due to a confusion in the specification of the deterministic terms included in the VECM between the cases considered by Osterwald-Lenum (1992) and Pesaran, Shin and Smith (2000). The result is a tendency to reject the null of no cointegration too often. However, a simple adjustment of the critical values is enough to deal with the problem.Cointegration, Johansen Test.
