Estimation of arrest careers using hierarchical stochastic models

This paper introduces a general procedure using hierarchical stochastic models for characterizing criminal careers within a population of heterogeneous offenders. Individuals engage in criminal careers which are treated as stochastic processes governed by fixed parameters (e.g., a rate parameter), and these parameters come from specified distributions. The parameters of these distributions at the upper level of the hierarchy must then be specified. The models are estimated using data on all persons arrested at least once in the six-county Detroit Standard Metropolitan Statistical Area during the 4 years 1974–1977 for a criterion offense (an index crime other than larceny) and arrested at least once for robbery through April 1979. The collected data set is not a random sample of all such offenders in the population. There is a bias toward selecting those with a higher arrest frequency. In order to make more general inferences, statistical adjustment was needed to overcome the arrest-frequency sampling bias. We construct a series of models for the arrest career and fit the models with the data set of arrests. After correcting biases in the data, we estimate the model parameters using empirical Bayes methods and then examine the resulting models.     

INVESTIGATING THE STABILITY OF CO‐OFFENDING AND CO‐OFFENDERS AMONG A SAMPLE OF YOUTHFUL OFFENDERS*

Scholars have long argued that delinquency is a group phenomenon. Even so, minimal research exists on the nature, structure, and process of co‐offending. This investigation focuses on a particular void, namely the stability of 1) co‐offending and 2) co‐offender selection over time, for which divergent theoretical expectations currently exist that bear on issues central to general and developmental/life‐course theories of crime. By relying on individual‐level, longitudinal data for a sample of juvenile offenders from Philadelphia, we find that distinct trajectories of co‐offending exist over the course of the juvenile criminal career. This inquiry also develops an individualized measure of co‐offender stability, which reveals that delinquents generally tend not to “reuse” co‐offenders, although frequent offenders show a greater propensity to do so. The discussion considers the theoretical and policy implications of these findings as well as provides some avenues for future research.     

New Evidence on the Monetary Value of Saving a High Risk Youth

There is growing interest in crime prevention through early youth interventions; yet, the standard United States response to the crime problem, particularly among juveniles, has been to increase the use and resource allocation allotted toward punishment and incapacitation and away from prevention and treatment. At the same time, longitudinal studies of delinquency and crime have repeatedly documented a strong link between past and future behavior and have identified a small subset of offenders who commit a large share of criminal offenses. These findings suggest that if these offenders can be identified early and correctly and provided with prevention and treatment resources early in the life course, their criminal activity may be curtailed. While researchers have studied these offenders in great detail, little attention has been paid to the costs they exert on society. This paper provides estimates of the cost of crime imposed on society by high risk youth. Our approach follows and builds upon the early framework and basic methodology developed by Cohen (J Quant Criminol 14: 5–33, 1998), by using new estimates of the costs of individual crimes, ones that are more comprehensive and that significantly increased the monetary cost per crime. We also use new estimates on the underlying offending rate for high risk juvenile offenders. We estimate the present value of saving a 14-year-old high risk juvenile from a life of crime to range from $2.6 to $5.3 million. Similarly, saving a high risk youth at birth would save society between $2.6 and $4.4 million.

It is the worst time in living history to be a law graduate: or is it? Does Australia have too many law graduates?

According to the Australian legal profession and media, law schools are producing too many graduates relative to the number of vacancies within the profession. This claim, however, is hardly new. This paper identifies a number of junctions at which there has been concern about the overproduction of law graduates, showing that this discourse appears during periods of major economic stress. It also shows that until the most recent episode of concern, the perception that there are too many law graduates relative to employment opportunities has not been supported by empirical evidence. In the past, the increasing supply of law graduates has been met with increasing demand. However, the legal profession is now facing unprecedented market competition and restructure, and opportunities in the profession for new graduates have declined. This still does not mean that the law schools are producing too many graduates. The current cohort of graduates is likely to continue into a professional occupation, although not necessarily in private legal practice, and there is a lack of lawyers working in disadvantaged communities.     

Examining the Divergence Across Self-report and Official Data Sources on Inferences About the Adolescent Life-course of Crime

Both self-report and official crime data have known limitations, leading to the critical question as to whether inferences about the adolescent life-course of crime are different across these data sources. Using both official and self-report arrest data on a sample of subjects drawn from the Project on Human Development in Chicago Neighborhoods (PHDCN) longitudinal cohort study, this paper examines the extent to which individual age-arrest curves are comparable across these data sources. Particular attention is given to examining whether criminal career dimensions, namely participation, frequency of arrest, age of onset, and continuity in behavior, are similar across data sources. Additionally, this paper examines whether the key predictors of youth crime (e.g., family processes, peer influence, and neighborhood disadvantage) function similarly across measurement types. Findings reveal that a sizable number of youth self-report being arrested without having a corresponding official arrest record, and a sizable proportion of those youth with an official arrest record fail to self-report that they had been arrested. Despite significant differences across the two arrest measures on many criminal career dimensions, the effects of family supervision, parent–child conflict, and neighborhood disadvantage operate similarly across data types.

Post‐ministerial occupation in advanced industrial democracies: Ambition,individual resources and institutional opportunity structures

The post‐office occupation of former cabinet members remains basically unexplored in both single‐case and comparative studies. Is being a minister just a career tout court, or does serving in executive office facilitate movement to other positions? This article sheds new light on this question by advancing the theoretical development and empirical understanding of the various types of post‐ministerial occupation. The analysis takes into account ex‐ministers’ ambition, political capital resources and the institutional opportunity structures that might well affect both ambition and individual resources. Additionally, given that access to executive office is profoundly gendered, the article addresses the central question of whether post‐ministerial occupations similarly present differential patterns for women and men. The empirical results of a cross‐national comparison of 23 advanced industrial democracies show that, for most departing ministers, serving in executive office is indeed a stepping stone to other positions. Post‐office trajectories are not only shaped by ex‐ministers’ political capital resources such as seniority, party office, policy expertise and type of portfolio held while in cabinet, but also by different institutional factors that present country‐specific combinations. Specifically, systemic variables shape the relevance of political capital resources and affect how ambition is constructed and towards which goals. Strong gendered post‐office patterns are not found, although some intriguing gender differences are observed.     

Does Incapacitation Reduce Crime?

Questions and answers about incapacitation abound in all discussions about criminal justice policy. They are among the most pressing of all research issues, yet estimates about the incapacitation effect on crime vary considerably, and most are based on very old and incomplete estimates of the longitudinal pattern of criminal careers. This paper provides an overview of the incapacitation issue, highlights information on recent estimates of criminal careers that are useful to the incapacitation model, and outlines an ambitious research agenda for continued and expanded work on incapacitation and crime that centers on developing better estimates of the characteristics of criminal careers and their relevance to policy choices.
