Mortgage Backed Securities (MBS) are among the most complex of all financial instruments. Analysis of MBS requires blending empirical analysis of borrower behavior with mathematical modeling of interest rates and home prices. Over the past 25 years, Davidson and Levin have been at the leading edge of MBS valuation and risk analysis. Mortgage Valuation Models: Embedded Options, Risk and Uncertainty is a detailed description of the sophisticated theories and advanced methods that the authors employ in real-world analysis of mortgage backed securities. Issues such as complexity, borrower options, uncertainty, and model risk play a central role in their approach to valuation of MBS. The book describes methods for modeling prepayments and defaults of borrowers. It explores closed form, backward induction and Monte Carlo valuation using the Option-Adjusted-Spread (OAS) approach, explains the origin of OAS and its relationship to model uncertainty. With reference to the classical CAPM and APT, the book advocates extending the concept of risk-neutrality to modeling home prices and borrower options, well beyond interest rates. The coverage spans the range of mortgage products from loans, TBA (to be announced) pass-through securities to subordinate tranches of subprime-mortgage securitizations and describes valuation methods for both agency and non-agency MBS including pricing new loans; Davidson and Levin put forth new approaches to prudent risk measurement, ranking, and decomposition that can help guide traders and risk managers. It reveals quantitative causes of the 2007-09 financial crisis and provides insights into the future of the US housing finance system and mortgage modeling. Despite the advances in mortgage modeling and valuation, this remains an ever-evolving field. Mortgage Valuation Models will serve as a foundation for the future development of models for mortgage-backed securities.

The unseen letters of the only British officer to spend three years in the trenches throughout the First World WarColonel Graham Chaplin, commander of the Cameron Highlanders, wrote letters from the trenches almost daily to the wife he had married just before the war began. Even if he had no time to write, he would at least send a postcard to reassure her he was 'Quite well'. These personal and loving letters give a rare insight into the mind of a serving officer, his worries about his men and his family back home, his concern for the progress of the war (however cautiously phrased) and his comments on the growing list of friends dead or wounded.Having once refused what he considered unacceptably dangerous orders to send his troops over the top during the Battle of Loos, Chaplin wasn't promoted out of the trenches until 1917. Respected and trusted by his men, he was, even so, the only officer to whom this happened.Andrew Davidson, author of the highly praised Fred's War, analyses Chaplin's unique status and weaves around his letters a fascinating portrait of a soldier's life and of the war on the Western Front.

The spread of modernity throughout the non-Western world has had transformative effects not only on governments and economies but on the lives of individuals as well. The constraints and opportunities of modernization inevitably lead to the breakdown and supplanting of older social relations and livelihoods. In this volume Andrew P. Davidson examines the Nuba Mountain region of western Sudan to show how individuals and families struggle to maintain or expand their well-being in the face of continuous uncertainty, when control of their destinies is increasingly slipping out of the comforting confines of the village.As in many third world regions, changes in agriculture and market activity have occurred in the Nuba mountains in a far more compressed tune frame than in Europe. Davidson charts the social effects of the rationalization process by concentrating on the household as a mediating structure between the individual and the larger society. In his analysis the livelihood strategies of households act as a microcosm for the unevenness of development that is characteristic of modernizing economies. Davidson offers a comparative and historical examination of economic life in three villages in order to better understand the capacities and limitations that ultimately condition what people can and cannot do. He shows how the older lineage system based on communalism, kinship, and age-based hierarchy is being displaced by new forces of social organization and individual orientation which have eroded village cohesion and left the Nuba vulnerable to the Islamic-dominated government in Khartoum and the ravages of the continuing Sudanese civil war.In its combination of empirical analysis, ethnographic fieldwork, and theoretical inquiry In the Shadow of History reconceptualizes development in such a way that the dynamics of historical transformation are made clear. This study hi the classic anthropological tradition will be a valuable resource for anthropologists, economists, historians, and Africa area specialists.

This title was first published in 2003.The public sector plays a dominant international role in the provision of agricultural extension and services. This role has been the subject of much debate. Some argue for extension's privatization, claiming that a market driven system provides the most rational and efficient means of information delivery. Based on extensive empirical research from the Punjab (Pakistan), this volume examines the comparative effectiveness of public and private extension services from the perspective of farmers. It also focuses on information from extension agents about their respective organizations and work environments. In so doing, the book expands and elaborates on the practical considerations of privatization and information delivery. It then broadens out into a discussion of alternative means of extension delivery, focusing on participatory approaches, education theory and pluralism.

A young man is fighting for his life.Into his room walks a bewitching woman who believes she can save him.Their journey will have you believing in the impossible.The nameless and beautiful narrator of The Gargoyle is driving along a dark road when he is distracted by what seems to be a flight of arrows. He crashes into a ravine and wakes up in a burns ward, undergoing the tortures of the damned. His life is over - he is now a monster.But in fact it is only just beginning. One day, Marianne Engel, a wild and compelling sculptress of gargoyles, enters his life and tells him that they were once lovers in medieval Germany. In her telling, he was a badly burned mercenary and she was a nun and a scribe who nursed him back to health in the famed monastery of Engelthal. As she spins her tale, Scheherazade fashion, and relates equally mesmerising stories of deathless love in Japan, Greenland, Italy and England, he finds himself drawn back to life - and, finally, to love.
