The purpose of this paper is to investigate the outcomes of Indonesian power projects as representative projects of Asian emerging economies that were procured via public-private partnerships (PPPs) and traditional public sector procurement. Power generation infrastructure delivery in emerging economies frequently seeks private participation via PPPs as one of the key mechanisms to attract private finance. Undertaking a comparative benchmark study of the outcomes of Indonesian power projects provides an opportunity to explore the historic evidence as to whether PPPs deliver better outcomes than traditional public procurement in emerging economies.
This paper reports on a study of the performance of 56 Indonesian power projects procured via either PPPs or traditional procurement. First, it focusses on project time and cost outcomes of power plant facility during construction and commissioning and then extends this comparison to consider the operating availability of power plants during their first two years of operation.
The results indicate that PPP projects had superior time and operating availability to those procured traditionally whereas no significant differences were identified in the cost performance between PPPs and traditionally procured projects. These findings highlight the importance of adopting policies that are supported by broader sources of international financiers and high quality power plant developers.
The quality performance analyses of projects (based on equivalent available factor indices) were limited to the power plants in the Java-Bali region where the majority of projects are large scale power plants.
This study provides an empirical basis for governments of emerging economies to select the most beneficial procurement strategy for power plant projects. It highlights the importance of selecting experienced providers and to adopt policies that attract high quality international project financiers and power plant developers. This includes the need to ensure the commercial viability of projects and to seriously consider the use of cleaner power technologies.
This study is the first to compare the outcomes of power projects in Asian emerging economies delivered via PPPs against those delivered by traditional public procurement that includes consideration of the quality of the delivered product.

Purpose – The purpose of this study is to develop a numerical framework to predict the time-dependent probability of failure of a bridge subjected to multiple vehicle impacts. Specially, this study focuses on investigating the inter-relationship between changes in life-cycle parameters (e.g., damage size caused by vehicle impact, loss of initial structural capacity, and threshold intervention) and bridges probability of failure.
Design/Methodology/Approach – The numerical procedure using MATLAB program is developed to compute the probability failure of a bridge. First, the importance and characteristics of life-cycle analysis is described. Then, model for damage accumulation and life cycle as a result of heavy vehicle impacts is discussed. Finally, the probability of failure of a bridge subjected to vehicle impacts as a result of change in life-cycle parameters is presented.
Findings – The results of study show that damage size caused by both vehicle impacts and loss of initial structural capacity have a great impact on the long-term safety of bridges. In addition, the probability of failure of a bridge under different threshold limits indicates that the structural intervention (e.g., repair or maintenance) should be undertaken to extend the service life of a bridge.
Research Limitations/Implications – The damage sizes caused by heavy vehicle impacts are based on simple assumptions. It is suggested that there would be a further study to estimate the magnitude of bridge damage as a result of vehicle impact using the full-scale impact test or computational simulation.
Practical Implications – This will allow much better predictions for residual life of bridges which could potentially be used to support decisions on health and maintenance of bridges.
Originality/Value – The life-cycle performance for assessing the time-dependent probability of failure of bridges subjected to multiple vehicle impact has not been fully discussed so far.

Little systematic work has been completed on the incidence of employee ownership in a Chinese context. Similar to the situation in Eastern Europe, this type of ownership was quite widespread in China, particularly during the 1990s. Based on the existing literature and available statistical data, the purpose of this paper is to identify drivers of, and barriers to, the development of employee ownership in China.
The scattered evidence from the literature and official statistical sources are collected and structured in a systematic analysis where the drivers and barriers for employee ownership in the transition process from plan to market are identified at three levels: society, the company and the individual.
Employee ownership developed as a transitory stage between state and private ownership; employees acquired ownership stakes as part of the privatisation of small- and medium-sized state-owned enterprises as well as collectively owned enterprises. However, in most cases the dynamics of ownership resulted in dominant ownership by managers. This trend became more noticeable at later stages of the privatisation process.
The paper shows how policies and institutional settings at the society level are determining for the development of employee ownership.
The contribution of the paper is to give a general and systematic analysis of the development of employee ownership in China both based on a comprehensive literature review and by utilising existing statistical sources.

The purpose of this study is to examine how performance appraisal process is associated with organizational citizenship behavior, under the light of social exchange theory and impression management theory, using affective commitment as a mediator and rating‐reward linkage as a moderator.
Using a multi‐source sample (n=777), the authors examined the mediating role of affective commitment with structural equation modeling and Sobel tests, and the moderating role of rating‐reward linkage with ordinary least squares (OLS) regression models.
The relationship between performance appraisal process and organizational citizenship behavior was partially mediated by affective commitment, and perceived rating‐reward linkage strengthened the direct association between appraisal process and organizational citizenship behavior whereas it weakened the relationship between appraisal process and affective commitment.
The study adds to knowledge of how performance appraisal process relates to organizational citizenship behavior – through affective commitment. Further, the moderating role of rating‐reward linkage deepens understanding of the underlying motives of organizational citizenship behavior. The findings strengthen the valence of using social exchange theory to explain how performance appraisal process is associated with organizational citizenship behavior and suggest the value of incorporating impression management to supplement social exchange theory.
