Nativist but not alienated A comparative perspective on the radical right vote in Western Europe

Abstract: In the present study I use large-scale survey data to compare radical right voting to other forms of electoral behavior in Western Europe. The chosen method, multilevel multinomial logistic regress...

Everything you always wanted to know about log-periodic power laws for bubble modeling but were afraid to ask

Abstract: Sornette, Johansen, and Bouchaud (1996), Sornette and Johansen (1997), Johansen, Ledoit, and Sornette (2000) and Sornette (2003a) proposed that, prior to crashes, the mean function of a stock index price time series is characterized by a power law decorated with log-periodic oscillations, leading to a critical point that describes the beginning of the market crash. This article reviews the original log-periodic power law model for financial bubble modeling and discusses early criticism and recent generalizations proposed to answer these remarks. We show how to fit these models with alternative methodologies, together with diagnostic tests and graphical tools, to diagnose financial bubbles in the making in real time. An application of this methodology to the gold bubble which burst in December 2009 is then presented.

Observation of new resonances decaying to $J/\psi K^+$ and $J/\psi \phi$

Abstract: The first observation of exotic states with a new quark content c c ¯ u s ¯ decaying to the J / ψ K + final state is reported with high significance from an amplitude analysis of the B + → J / ψ ϕ K + decay. The analysis is carried out using proton-proton collision data corresponding to a total integrated luminosity of 9 fb - 1 collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The most significant state, Z c s ( 4000 ) + , has a mass of 4003 ± 6 - 14 + 4 MeV , a width of 131 ± 15 ± 26 MeV , and spin parity J P = 1 + , where the quoted uncertainties are statistical and systematic, respectively. A new 1 + X ( 4685 ) state decaying to the J / ψ ϕ final state is also observed with high significance. In addition, the four previously reported J / ψ ϕ states are confirmed and two more exotic states, Z c s ( 4220 ) + and X ( 4630 ) , are observed with significance exceeding 5 standard deviations.

Market structure, technological gap and vertical linkage effects from foreign direct investment

Abstract: This paper is based on the model of backward linkages from foreign direct investment (FDI) Lin/Saggi (2003), where the market structure of the final goods sector is represented by a monopoly or Cournot oligopoly, and the supplier sector - by a pure monopoly. We extend this model by examining cases of perfect competition and a vertically integrated domestic company in the intermediate goods market. Our analysis shows that coming of foreign companies to the final goods sector provides positive backward linkage effects. Although this result doesn't depend on the market structure in the final goods sector, the latter significantly affects the size of FDI linkage effects - the more competitive is the intermediate goods sector, the larger are the backward linkage effects. They reach their maximum under perfect competition in the intermediate goods market, minimum - under monopoly in this sector, and medium size - when a vertically integrated local firm exists in the market. We have also discovered that a more competitive market structure per se doesn't guarantee larger positive effects of FDI. It is important that in addition to a competitive structure local firms do not significantly lag behind foreign firms in their technological level.
