高绩效工作系统与智力资本的关系研究

最近十几年,智力资本越来越受到学术界和企业界的重视。文章通过文献回顾发现,尽管已经有从雇佣关系和职能角度对人力资源管理与智力资本关系的研究;但是从高绩效工作系统角度进行的研究还很缺乏。而且,深入分析高绩效工作系统与智力资本各维度关系的实证研究更为鲜见。文章通过以北京、上海、广东和山西等地204家企业为样本,进行实证检验后发现:高绩效工作系统能够促成智力资本的全面发展;并且高绩效工作系统的内部匹配会对人力资本和客户资本具有显著的正向影响。     

When do B2B brands influence the decision making of organizational buyers? An examination of the relationship between purchase risk and brand sensitivity

The dominant perspective on organizational buying behavior suggests that buyers tend to rely on objective criteria when making product choice decisions and that the potential influence of subjective cues, such as brands, on buyer decision making decreases with increasing risk. An alternative perspective, confirmed in this study by in-depth interviews with various managers, suggests that brands serve as a risk-reduction heuristic, whereby the influence of brands on decision making increases as a function of risk. Building on risk and information processing theories, this research builds on these complementary perspectives to propose that risk and brand sensitivity relate in a U-shaped manner, where brand sensitivity is highest in relatively low- or high-risk situations. The results of scenario- and survey-based field studies—involving 206 and 180 members of buying centers, respectively—suggest that both perspectives have merit and support the proposed nonlinear relationship. Moreover, the findings reveal that the risk-brand sensitivity relationship is moderated by competitive intensity, such that the linear (negative) and quadratic (positive) effects are stronger when competitive intensity is low.

Employee experienced HPWPs and job performance: Roles of person-job fit and intrinsic motivation

The extant research on high performance work practices (HPWPs) mainly focuses on the organization level, with little research exploring employee experienced HPWPs and their impact on individual work outcomes. Whether and how employee experienced HPWPs contribute to individual job performance is investigated in this study, using three waves of data from 318 subordinate-supervisor dyads in three big auto manufacturing companies in China. Results show that HPWPs are positively related to individual job performance. Moreover, this relationship is fully mediated by employee person-job fit and intrinsic motivation.     

Quantile regression with sample selection: Estimating women's return to education in the U.S.

This study uses quantile regression techniques to analyze changes in the returns to education for women. The data used is the March Current Population Survey for the years 1968, 1973, 1979, 1986 and 1990. The first step in estimating the single (linear) index selection equation uses Ichimura's (1993) semiparametric procedure. To correct for an unknown form of a sample selection bias in the quantile regression, the second step incorporates a nonparametric method, using an idea similar to one developed by Heckman (1980) and Newey (1991) for mean regression, and Buchinsky (1998) for quantile regression.  The results show that: (a) the returns to education increased enormously for the younger cohorts, but very little for the older cohorts; (b) in general the returns are higher at the lower quantiles in the beginning of the sample period and higher at the higher quantiles by the end of the sample period; (c) there is a significant sample selection bias for all age groups at almost all quantiles; (d) toward the end of the sample period there is a significant convergence of the returns at the various quantiles, especially for the younger cohorts and age groups; and (e) the semiparametric estimates of the selection equation are considerably different from those obtained for a parametric probit model.     

THE CHOICE OF CELLS IN CHI–SQUARE TESTS

The choice of cells in chi–square goodness of fit tests is a classical problem. Some recent results in this area are discussed. It is shown that the likelihood ratio of alternatives w.r.t. null distributions plays a key role when judging different procedures. The discussion centers on the case of a simple hypothesis, but location–scale models and tests of independence in contingency tables are also considered.

Business strategy,technology policy and firm performance

This paper presents a study of the relationships among select business strategy dimensions, technology policy dimensions, and firm performance. The research sought to identify how these variables interrelate at the bivariate and multivariate levels. Data were collected from 103 manufacturing-based firms representing 28 mature industries. Results show that technology policy choices vary widely across firms with different business strategies, and that business strategy affects the strength of the relationship between firm performance and particular technology policies.     

Regression Revisited

Sir Francis Galton introduced median regression and the use of the quantile function to describe distributions. Very early on the tradition moved to mean regression and the universal use of the Normal distribution, either as the natural ‘error’ distribution or as one forced by transformation. Though the introduction of ‘quantile regression’ refocused attention on the shape of the variability about the line, it uses nonparametric approaches and so ignores the actual distribution of the ‘error’ term. This paper seeks to show how Galton's approach enables the complete regression model, deterministic and stochastic elements, to be modelled, fitted and investigated. The emphasis is on the range of models that can be used for the stochastic element. It is noted that as the deterministic terms can be built up from components, so to, using quantile functions, can the stochastic element. The model may thus be treated in both modelling and fitting as a unity. Some evidence is presented to justify the use of a much wider range of distributional models than is usually considered and to emphasize their flexibility in extending regression models.
