On The Total Duration Of Negative Surplus Of A Risk Process With Two-Step Premium Function, Pavlina Jordanova Dec 2007

On The Total Duration Of Negative Surplus Of A Risk Process With Two-Step Premium Function, Pavlina Jordanova

Applications and Applied Mathematics: An International Journal (AAM)

We consider a risk reserve process whose premium rate reduces from cd to cu when the reserve comes above some critical value v. In the model of Cramer-Lundberg with initial capital u ≥ 0, we obtain the probability that ruin does not occur before the first up-crossing of level v. When u < v, following H. Gerber and E. Shiu (1997), we derive the probability that starting with initial capital u ruin occurs and the severity of ruin is not bigger than v. Further we express the probability of ruin in the two step premium function model - ψ (u,v), by the last two probabilities. Our assumptions imply that the surplus process will go to infinity almost surely. This entails that the process will stay below zero only temporarily. We derive the distribution of the total duration of negative surplus and obtain its Laplace transform and mean value. As a consequence of these results, under certain conditions in the Model of Cramer-Lundberg we obtain the expected value of the severity of ruin. In the end of the paper we give examples with exponential claim sizes.

Climate. Scrubbing The Sky: Climate Change And The Productive Center, Marcy Murninghan Jul 2007

Climate. Scrubbing The Sky: Climate Change And The Productive Center, Marcy Murninghan

New England Journal of Public Policy

This article sketches out the efforts of government, business, and civil society to address the problem of climate change. It identifies some of the key initiatives underway — including proposals for more stringent caps on greenhouse gas (GHG) emissions; the creation of a market-based trading system that provides incentives and profits for entities that reduce their GHG emission levels; more robust research and development of alternative energy sources as well as new approaches to traditional ones; and continued public education — and portrays the bipartisan, collaborative, multilateral nature of saving Mother Nature. While acknowledging that ultimately these efforts may be …

Biometrics For Hospitality And Tourism: A New Wave Of Information Technology, Bomi Kang, Kathleen Pearl Brewer, Billy Bai Jan 2007

Biometrics For Hospitality And Tourism: A New Wave Of Information Technology, Bomi Kang, Kathleen Pearl Brewer, Billy Bai

Hospitality Review

The technologies that empower biometrics have been around for a number of years, but until recently these technologies have been viewed as exotic. In the not too distant future biometrics will be used to regulate internal processes and to improve services in the hospitality and tourism industries. This paper provides an understanding of the current use of biometrics in general and its practical value for the future in hospitality and tourism. The study presents a review of current practices of biometrics with special reference to the hospitality and tourism businesses, addresses key issues imposed by this technology, and identifies business …

Seeing The Forest For The Trees: The Future Of Timber Investing In The North Woods -- A Conversation With Clark S. Binkley, Peter Howell

Maine Policy Review

In this conversation with Peter Howell, Clark Binkley draws on his long-term experience as a timberland investment manager to give his analysis of and forecast for timber markets and timber investing in the Northern Forest. While he is not optimistic about the current prospects for such investments, he does believe that there are some opportunities in conservation easements, residential development, and possibly biofuels and carbon credits.
