关于企业边界的理论评述与思考

企业边界理论存在的不足主要有:交易成本经济学缺乏环境变化的动态分析;新古典理论对不少现象缺乏解释力;竞争优势理论缺少深度分析;迈克尔的分析框架不能解释中国的现实问题。鉴于企业边界问题复杂而动态,因此企业边界的理论研究有待进一步深化。

Sex Differences in Age Patterns of Delinquent/Criminal Careers: Results from Poisson Latent Class Analyses of the Philadelphia Cohort Study

Applications of latent class analyses to the study of criminal careers have yielded results with implications for criminological theory. Distinct latent classes of individuals within various samples have been identified based upon the similarity of individuals with respect to their rate of offending across the teen and adult years, net of the effects of other regressors. In previous research on samples of males taken from the cities of London and Philadelphia, four and five such categories have been identified respectively, ranging from a group of nonoffenders to a group of chronic offenders. However, the question of whether similar findings hold for females has not been adequately addressed, in part due to the scarcity of longitudinal samples with sizable female populations. Data from the Second Philadelphia Cohort are used to address this and related questions. First, are there latent classes of female offenders? Second, if such categories do exist, how do they compare? Third, how do classes of male and female offenders compare on key measures of criminal careers? Analyses of the samples yield differing numbers of classes for males and females. Gender invariances as well as differences in patterns of offending are also found and are discussed.

Identifying Unit-Dependency and Time-Specificity in Longitudinal Analysis: A Graphical Methodology

Longitudinal analysis in criminology and other social sciences has become an important research tool because it allows us to draw conclusions from observing how multiple units change over time. Unfortunately, its results are more vulnerable to potential influences of unusual observational units or periods of time. Current leverage diagnostics are designed for cross-sectional analysis and are fallible when applied to longitudinal models. This article introduces a graphical diagnostic methodology to systematically examine the sensitivity of longitudinal results to extreme observational units and periods of time—unit-dependency and time-specificity. Further the article illustrates its use with an example testing policy effects on black and white female victimization of intimate partner homicide. Results are displayed in an easily understood graph that provides a snapshot of the results' time-specific patterns and robustness to unit-dependency. Currently, comparable tests for panel analysis are tedious and cumbersome. With this new illuminating methodology, researchers and policy-makers can easily decide whether a time-specific or unit-dependent pattern is consequential.     

The multidimensionality of crime: A comparison of techniques for scaling delinquent careers

The construction of typologies of criminal behavior can benefit from the use of multidimensional analytic methods. Yet while some studies have applied such techniques to crime data (e.g., Shortet al, 1963; Nutch and Bloombaum, 1968; Chaiken and Chaiken, 1982), few have examined the assumptions of these methods as they apply to arrest histories. We argue that arrest histories represent a special form of data that are not ideally suited to standard multidimensional analyses. An examination of the different theoretical assumptions of factor analysis, multidimensional scaling, and variance centroid scaling (a form of correspondence analysis) reveals marked difierences in what is being uncovered by the analysis. In general, these claims are supported by an application of each technique to the arrest histories of 767 chronic juvenile delinquents.
