We introduce an infinite class of polynomial sequences at(n; z) with integer parameter t > 1, which reduce to the well-known Stern (diatomic) sequence when z = 1 and are (0, 1)-polynomials when t > 2. Using these polynomial sequences, we derive two different characterizations of all hyperbinary expansions of an integer n > 1. Furthermore, we study the polynomials at(n; z) as objects in their ow...

Unemployment is a major concern for the transforming economies of Central and Eastern Europe. The "flow approach" to labor markets suggests that unemployment is an important complement to the trans formation process and that labor market institutions will help determine the long run rate of unemployment in these economies. Considerable cross-country variation can be observed in Eastern Europe w...

This paper extends and confirms the report of Calabrese (Calabrese, E. J. (2011b). Muller's Nobel Lecture on dose-response for ionizing radiation: Ideology or science? Arch. Toxicol. 85, 1495-1498) that Hermann J. Muller knowingly made deceptive comments in his 1946 Nobel Prize Lecture (Muller, H. J. (1946). Nobel Prize Lecture. Stockholm, Sweden. Available at http://www.nobelprize.org/. Access...

The Stern Review of the Economics of Climate Change (Stern et al. 2006a, b; Stern 2007) has been the catalyst of an enormous amount of discussion since its release in the fall of 2006. Policy makers see it as an authoritative report that makes an economic case for rapid reduction of greenhouse gas emissions. Most economists have a different opinion of the quality of the analysis, even though th...

The Stern Review of the Economics of Climate Change (Stern et al., 2006) is a report to the Prime Minister and the Chancellor of the Exchequer of the United Kingdom. A team of 23 people, led by Sir Nicholas Stern and supported by many consultants, worked for a little over a year to produce a report of some 700 pages on the economics of climate change. The report says many things, some better su...

This paper proposes a calculational approach to prove properties of two well-known binary trees used to enumerate the rational numbers: the Stern-Brocot tree and the Eisenstein-Stern tree (also known as CalkinWilf tree). The calculational style of reasoning is enabled by a matrix formulation that is well-suited to naturally formulate path-based properties, since it provides a natural way to ref...
