Citizen Support for Hospital Privatization: A Hierarchical Cross-National Analysis

The movement for a new public management (NPM) holds that citizens will put aside partisan and ideological differences to support more efficient service delivery. Focusing on hospital privatization, a multi-national sample is utilized to investigate this assertion. Generalized hierarchical linear modeling (GHLM) is employed as the method of statistical analysis. The findings with regard to privatizing hospitals reveal that citizens develop their policy position by reference to a combination of symbolic political variables, service demand, self-interest, information levels, and political efficacy. The results cast doubt on the assertion that partisan differences will be set aside as citizens consider privatization reforms.

关系成员企业管理者社会资本水平其机会主义行为间关系的实证研究——以中外合资企业为例

本文以中外合资企业为主要研究对象,就关系成员企业管理者社会资本水平与其在特定关系中的机会主义行为水平的联系及其对关系绩效的影响进行了实证研究。研究结果首次证实了企业管理者社会资本会提高其在特定关系中的机会主义倾向这一潜在关系的存在,但这种机会主义行为主要体现在对关系程序控制权的获取上,并不会降低社会资本在提升关系收益水平方面的价值,同时也不会影响关系成果分配的公平性。本研究的相关结论对于进一步的研究与企业管理实践均有一定价值。     

The Impact of Competitive Strategy and Supply Chain Strategy on Business Performance: The Role of Environmental Uncertainty*

This article investigates the relationships among competitive strategy, supply chain strategy, and business performance while examining the moderating effect of environmental uncertainty. A total of 604 questionnaires were collected from three cities in China, and the statistical results show significant moderating effects of external environment on the relationships among competitive strategy, supply chain strategy, and business performance. Firms that primarily focus on a differentiation strategy emphasize an agile supply chain strategy. Cost leaders are inclined to implement both lean and agile supply chain strategies, but their emphasis on agile strategy is significantly greater in a volatile environment than in a stable environment. The choice of supply chain strategy does not appear to be an “either‐or” decision and firms could adopt either a lean or an agile strategy, or both, depending on the environment. This article provides significant managerial implications for supply chain practitioners to co‐align supply chain strategy and competitive strategy with the environment to improve performance.     

Nonparametric Instrumental Regression

The focus of this paper is the nonparametric estimation of an instrumental regression function ϕ defined by conditional moment restrictions that stem from a structural econometric model E[Y−ϕ(Z)|W]=0, and involve endogenous variables Y and Z and instruments W. The function ϕ is the solution of an ill‐posed inverse problem and we propose an estimation procedure based on Tikhonov regularization. The paper analyzes identification and overidentification of this model, and presents asymptotic properties of the estimated nonparametric instrumental regression function.

Internal labor markets and the effects of structural change: Job mobility in Korean labor markets between 1998 and 2000

This study examines job mobility in Korean labor markets since the 1997 economic crisis. The rising job mobility in Korea is analyzed by focusing on structural change in labor markets. Using the Korean Labor and Income Panel Study and discrete-time event history analysis, I estimate the job-stabilizing effects of internal labor markets and the effects of structural change on job mobility. The major findings are as follows: First, I found that internal labor markets were weakening between 1998 and 2000. Second, the job-stabilizing effects of internal labor markets on job mobility diminished between 1998 and 2000. Finally, the magnitude of the effects of internal labor markets on job mobility was contingent on the level of structural change. The effect of internal labor markets on job mobility was stronger in turbulent or contracting industries. This effect, however, also became weaker over time. The implications for Korean labor markets are discussed.
