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 female considered was collected in Haifa, Israel, by V. Roth, March 1987 (HUJ14494) and was mis-matched with males of <i>Z. meronensis</i> Levy, 1998. Due to the discovery of the right matching mates of the latter, the female is here transferred and given a new name.</p>Published as part of <i>Levy, Gershom, 2009, New ground-spider genera and species with annexed checklist of the Gnaphosidae (Araneae) of Israel, pp. 1-49 in Zootaxa 2066</i> on page 34, DOI: <a href="http://zenodo.org/record/186952">10.5281/zenodo.186952</a>

Ebo eremus Levy 1999
No full text<i>Ebo eremus</i> Levy, 1999 <p>Figs. 47, 48</p> <p>Adult male from Avedat, Israel, leg. Efrat Elimelech, along with female, March 24, 2004, pitfall trap (HUJ 15480).</p> <p> <b>Description.</b> Carapace dorsally with brown sides and light-brown, broad median band turning almost white anteriorly. Sternum densely covered by small brown dots on light background. Opisthosoma grey with dark mid-dorsal marking and grey posterior chevrons. Legs yellow brown mottled with small dark spots.</p> <p> <i>Male.</i> Measurements: total length 3.3; carapace length 1.5, width 1.5, index 1.0; femur II length 3.0, width 0.3, length/width 10.</p> <p> <i>Palpus</i>. Patella with wide, brown retrolateral apophysis, and tibia with strong retrolateral apophysis with round distended tip (Figs. 47, 48). Tegulum with fine looping seminal tube terminating apically with sclerotized hook rising above whitish, elongated conductor (Fig. 47). Short hook-like tegular apophysis projects from concavity at retrolateral apical part of tegulum (Figs. 47, 48).</p> <p> <b>Diagnosis.</b> The previously unknown male of <i>Ebo eremus</i> represents along with <i>E. patellidens</i> Levy a line of male species with palpi bearing a patellar apophysis (Levy 1977, figs. 36, 37). The shape of the tegular sclerites and of the peculiar tibial and patellar apophyses distinguish <i>E. eremus</i> clearly from <i>E. patellidens</i> and from all other <i>Ebo</i> species.</p> <p> <b>Distribution.</b> Israel: Central Negev.

Profits: The Views of Jerome Levy and Michal Kalecki
No full textProfits are the incentive for production and therefore employment in almost all of the world's economies; they also may represent exploitation of workers and consumers. Jerome Levy, using a complex process, derived the profits identity during the years 1908–1914. Michal Kalecki, taking advantage of the development of national accounting, derived it in the 1930s. Levy viewed the equation as a tool for developing policies that would enable capitalist economies to achieve high rates of employment. Recent American experience gives weight to his views. Kalecki's insights from the identity strengthened his belief that unemployment was inescapable under capitalism. He would find empirical support in Europe's high unemployment rates during the past two decades.
