The Levy sections theorem revisited
No full textThis paper revisits the Levy sections theorem. We extend the scope of the theorem to time series and apply it to historical daily returns of selected dollar exchange rates. The elevated kurtosis usually observed in such series is then explained by their volatility patterns. And the duration of exchange rate pegs explains the extra elevated kurtosis in the exchange rates of emerging markets. In the end our extension of the theorem provides an approach that is simpler than the more common explicit modeling of fat tails and dependence. Our main purpose is to build up a technique based on the sections that allows one to artificially remove the fat tails and dependence present in a data set. By analyzing data through the lenses of the Levy sections theorem one can find common patterns in otherwise very different data sets.Econophysics; Levy sections

The Impacts of the Climate Change Levy on business: Evidence from Microdata
No full textWe estimate the impacts of the Climate Change Levy (CCL) on manufacturing plants using panel data from the UK production census. Our identification strategy builds on the comparison of outcomes between plants subject to the CCL and plants that were granted an 80% discount on the levy after joining a Climate Change Agreement (CCA). Exploiting exogenous variation in eligibility for CCA participation, we find that the CCL had a strong negative impact on energy intensity and electricity use. We cannot reject the hypothesis that the tax had no detrimental effects on economic performance and on plant exit.Climate policy, carbon tax, United Kingdom, manufacturing, impact assessment

Agelescape affinis Levy 1996
No full textAgelescape affinis (KulczyIski, 1911) (Figs. 8 F–H, 15A) Agelena afFnis Kulczyński 1911: 45, pl. 2, fig. 53 (♀). Agelena afFnis: de Blauwe 1980: 2, figs. 1–2 (♀). Agelescape afFnis: Levy 1996: 90, figs. 14–15, 18–19 (♂ ♀). Material examined: ISRAEL: 1♀ (SMNH), Mt Meron, 22 February 2010 (C. Drees); 1♀ (SMNH), Upper Galilee, 900 m, N slope of Mt Meron, Meron Field School, 33°01′N 35°23.5′E, 25 April 2013 (S. L. Zonstein); 1♀ (SMNH), Upper Galilee, 900 m, N slope of Mt Meron, Meron Field School, 33°01′N 35°23.5′E, 25 April 2013 (S. L. Zonstein); 1♀ (SMNH), Ziv’on, woodland, 33°02′N 35°25′E, 773 m, 01 September 2005 (A. Timm, T. Assmann). Description: See Levy (1996). Remarks: The male of this species was first described by Levy (1996) who did not find any differences between it and A. livida (in both palpal and somatic characters). The palp of A. livida depicted by Levy (1996) differs from other illustrations available for this species (e.g. position of the embolic base, shape of the RTA, etc., cf. Figs. 4A and 4B), but we conclude this is because of differences in his illustrations rather than in the spiders, as no such palpal conformation was found in the extensive collections from Israel. Distribution: Syria, Israel, and Lebanon (?) (Fig. 15A). Despite being reported from Turkey in the World Spider Catalog (2020), the identifications of Turkish material by Brignoli (1978) refer to A. gideoni (per Levy 1996). The records of this species from Lebanon could refer to A. livida (per Levy 1996).Published as part of Zamani, Alireza & Marusik, Yuri M., 2020, A review of Agelenini (Araneae: Agelenidae: Ageleninae) of Iran and Tajikistan, with descriptions of four new genera, pp. 368-386 in Arachnology 18 (4) on pages 371-372, DOI: 10.13156/arac.2020.18.4.368, http://zenodo.org/record/392521

A Fermion Levy theorem
No full textThe notion of quantum process with continuous trajectories is defined in terms of mutual quadratic variations and it is proved that for classical stochastic processes, this notion of continuity of trajectories coincides with the usual one. Our main result is that any continuous trajectory difference martingale M which is a Grassmann measure with scalar non-atomic brackets is isomorphic to a Fermion white noise (mean zero Fermi-Gaussian family) whose covariance coincides with the brackets of M. This is a fermion version of the Levy representation theorem for classical Brownian motion
