"Overcoming America's Infrastructure Deficit, A Fiscally Responsible Plan for Public Capital Investment"
No full textCondemned bridges, dilapidated school buildings, contaminated water supplies, and other infrastructure shortcomings threaten American growth, productivity, and prosperity. S Jay Levy and Walter M. Cadette propose a plan for financing infrastructure projects that is designed to have minimal effect on the federal budget and to promote sound fiscal operation. Federal zero-interest mortgage loans to state and local governments for capital projects specified by Congress can cut the cost of such projects, achieve needed improvements in the nation's infrastructure, and thereby contribute to the American economy's future.

No full textFive items: 1) A detailed inventory, part of Levy’s will which lists 24 deeds for property in New York City acquired by Levy during 1833-1853 (1863). 2) Original water bill for his properties from Croton Aqueduct Department for 1199.65 (1862). 4) Letter referring to $8516.55 owed to Asahel S. Levy (Levy’s favorite nephew), trustee and executor of Levy’s will for his services (1866). 5) Letter in Levy’s own hand asking that no further complaints be made against him without cause by fellow officers and saying that he would not hesitate to promise to promote a better feeling “nor permit their indecent expressions of bad temper to put me in the wrong.” (1859)Digital ImageDigital finding aid available
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
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

Levy foraging in a dynamic environment - Extending the Levy search
No full textA common task for robots is the patrolling of an unknown area with inadequate information about target locations. Under these circumstances it has been suggested that animal foraging could provide an optimal or at least suboptimal search methodology, namely the Levy flight search. Although still in debate, it seems that predators somehow follow this search pattern when foraging, because it avoids being trapped in a local search if the food is beyond the sensory range. A Levy flight is a particular case of the random walk. Its displacements on a 2-D surface are drawn from the Pareto-Levy probability distribution, characterized by power law tails. The Levy flight search has many applications in optical material, ladars, optics, large database search, earthquake data analysis, location of DNA sites, human mobility, stock return analysis, online auctions, astronomy, ecology and biology. Almost all studies and simulations concerning the Levy flight foraging examine static or slowly moving (with respect to the forager) uniformly distributed resources. Moreover, in recent works a small swarm of underwater autonomous vehicles has been used to test the standard Levy search in the underwater environment, with good results. In this paper we extend the classical Levy foraging framework taking into consideration a moving target allocated on a 2- D surface according to a radial probability distribution and comparing its performance with the random walk search. The metric used in the numerical simulations is the detection rate. Simulations include the sensor resolution, intended as the maximum detection distance of the forager from the target. Furthermore, contrarily to the usual Levy foraging framework, we use only one target. Results show that Levy flight outperforms the random walk if the sensor detection radius is not too small or too large. We also find the Levy flight in the velocity of the center of mass model of a fish school according the Kuramoto equation, a famous model of synchronization phenomena. Finally, a discussion about the controversy concerning the innate or evolutionary origin of the Levy foraging is given. © 2015 Author(s). Licensee InTech
