This essay collection focuses on the relationship between continuous time models and Autoregressive Conditionally Heteroskedastic (ARCH) models and applications. For the first time, Modelling Stock Market Volatility provides new insights about the links between these two models and new work on practical estimation methods for continuous time models. Featuring the pioneering scholarship of Daniel Nelson, the text presents research about the discrete time model, continuous time limits and optimal filtering of ARCH models, and the specification and estimation of continuous time processes. This work will lead to a rapid growth in their empirical application as they are increasingly subjected to routine specification testing. Provides for the first time new insights on the links between continuous time and ARCH models Collects seminal scholarship by some of the most renowned researchers in finance and econometrics Captures complex arguments underlying the approximation and proper statistical modelling of continuous time volatility dynamics

Bridging the Gap to Continuous Time

Modelling Stock Market Volatility

Armed and Considered Dangerous is a book about "bad guys" and their guns. But Wright and Rossi contend that for every suspected criminal who owns and abuses a firearm, a hundred or more average citizens own guns for sport, for recreation, for self-protection, and for other reasons generally regarded as appropriate or legitimate. Armed and Considered Dangerous is the most ambitious survey ever undertaken of criminal acquisition, possession, and use of guns. There are vast differences between the average gun owner and the average gun-abusing felon, but the analyses reported here do not suggest any obvious way to translate these differences into gun control policies. Most policy implications drawn from the book are negative in character: this will not work for this reason, that will not work for that reason, and so on. When experts are asked, "Okay, then what will work?" they usually fall back on the old warhorses of poverty, the drug problem, or the inadequate resources of the criminal justice system, and otherwise have little to say. This is not a failure of social science. It simply asks more of the data than the data were ever intended to provide. Several of Wright and Rossi's findings have become "coin of the realm" in the gun control debate, cited frequently by persons who have long since forgotten where the data came from or what their limitations are. Several other findings, including many that are important, have been largely ignored. Still other findings have been superseded by better and more recent data or rendered anachronistic by intervening events. With the inclusion of a new introduction detailing recent statistics and updated information this new edition of Armed and Considered Dangerous is a rich source of information for all interested in learning about weapon behavior and ownership in America.

Since Peter H. Rossi, Mark W. Lipsey, and Howard E. Freeman first published Evaluation: A Systematic Approach, more than 90,000 readers have considered it the premier text on how to design, implement, and appraise social programs through evaluation. In this, the completely revised Seventh Edition, authors Rossi and Lipsey include the latest techniques and approaches to evaluation as well as guidelines to tailor evaluations to fit programs and social contexts. With decades of hands-on experience conducting evaluations, the authors provide scores of examples to help students understand how evaluators deal with various critical issues. They include a glossary of key terms and concepts, making this the most comprehensive and authoritative evaluation text available. Thoroughly revised, the Seventh Edition now includes * Substantially more attention to outcome measurement * Lengthy discussions of program theory, including a section about detecting program effects and interpreting their practical significance * An augmented and updated discussion of major evaluation designs * A detailed exposition of meta-analysis as an approach to the synthesis of evaluation studies * Alternative approaches to evaluation * Examples of successful evaluations * Discussions of the political and social contexts of evaluation

Toward a Structural Theory of Action: Network Models of Social Structure, Perception, and Action centers on the concept of social structure, perceptions, and actions, as well as the strategies through which these concepts guide empirical research. This book also proposes a model of status/role-sets as patterns of relationships defining positions in the social topology. This text consists of nine chapters separated into three parts. Chapter 1 introduces the goals and organization of the book. Chapters 2-4 provide analytical synopsis of available network models of social differentiation, and then use these models in describing actual stratification. Chapter 5 presents a model in which actor interests are captured. Subsequent chapter assesses the empirical adequacy of the two predictions described in this book. Then, other chapters provide a network model of constraint and its empirical adequacy. This book will be valuable to anthropologists, economists, political scientists, and psychologists.

The most accurate and comprehensive picture of homelessness to date, this study offers a powerful explanation of its causes, proposes short- and long-term solutions, and documents the striking contrasts between the homeless of the 1950s and 1960s and the contemporary homeless population, which is younger and contains more women, children, and blacks.

The Origins of Homelessness

Down and Out in America

In 1978, the Social and Demographic Research Institute of the University of Massachusetts, Amherst, received a grant from the National Institute of Justice to undertake a comprehensive review of the literature on weapons, crime, and violence in the United States. The purpose of the project is best described as a "sifting and winnowing" of the claims and counterclaims from both sides of the Great American Gun War - the perennial struggle in Ameri­can political life over what to do, if anything, about guns, about violence, and about crime. The review and analysis of the available studies consumed the better part of three years; the results of this work are contained in this volume.The intention of any review is to take stock of the available fund of knowledge in some topical area. Under the Gun is no different: our goal has been to glean from the volumes of previous studies those facts that, in our view, seem firmly and certainly established; those hypotheses that seem adequately supported by, or at least approximately consistent with, the best available research evidence; and those areas or topics about which, it seems, we need to know a lot more than we do. One of our major conclusions can be stated in advance: despite the large number of studies that have been done, many critically important questions have not been adequately researched, and some of them have not been examined at all.Much of the available research in the area of weapons and crime has been done by advocates for one or another policy position. As a consequence, the manifest intent of many "studies" is to persuade rather than to inform. We have tried to approach the topic from a purely agnostic point of view, treating as an open question what policies should be enacted with regard to gun, or crime, control. Thus, we have tried to judge each study on its own merits, on the basis of the routine standards normally applied to social-scientific research, and not on the basis of how effectively it argues for a particular policy direction. It would, of course, be presumptuous to claim that we have set aside all our own biases in conducting this study. Whether or not our treatment is fair and objective is clearly something for the reader, and not us, to decide.
