Grants structure when the type of public project is endogenous

This paper gives an insight into changes in intergovernmental grants structure, focusing on the type of public project. Presenting a simple model which incorporates the endogenous determination of project type and grants structure, the results show that as the relative cost encountered by central government in collecting public funds increases, the central government tends to choose types of projects which local governments prefer and adopt block grant systems. The resulting equilibrium is compared with an optimal solution based on an utilitarian welfare function. Received: December 22, 2000 / Accepted: September 20, 2001     

Assessing the performance of matching algorithms when selection into treatment is strong

This paper investigates the method of matching regarding two crucial implementation choices: the distance measure and the type of algorithm. We implement optimal full matching—a fully efficient algorithm—and present a framework for statistical inference. The implementation uses data from the NLSY79 to study the effect of college education on earnings. We find that decisions regarding the matching algorithm depend on the structure of the data: In the case of strong selection into treatment and treatment effect heterogeneity a full matching seems preferable. If heterogeneity is weak, pair matching suffices. Copyright © 2007 John Wiley & Sons, Ltd.     

The adoption of innovative work practices in service establishments

Using data from the 1994 US National Establishment Survey, the author investigates differences between manufacturing and service establishments in the use of five innovative work practices: total quality management, self-managed teams, job rotation, job sharing and flextime. Service establishments are more likely to use job sharing and flextime. Manufacturing establishments are more likely to use total quality management and self-managed teams. These results hold when controlling for establishments’ business strategies, worker demographics, institutional connections and use of technology. Determinants of adoption of total quality management, self-managed teams and flextime also varied by sector.     

Assessing the adoption of HRM by small and medium-sized manufacturing organizations

This paper reports on exploratory research which uses a comparative case-study approach with sixteen organizations to study the extent to which HRM has been adopted in traditional brownfield-site, small and medium-sized UK manufacturing organizations. The paper begins with a comparison of HRM practices across the sixteen organizations. It is argued that the most common HRM practices in these firms appeared to relate more to a traditional small firm approach than to any proactive attempt to adopt HRM. The analysis shows that very few of the organizations adopted a strategic approach towards HRM with an integrated set of policies related to corporate strategy being put forward. Instead, the dominant approach seemed to be one of reactive, opportunistic pragmatism, showing little development from the standard modern approach identified as most common in the early 1980s. On the other hand, three organizations are shown to approximate quite closely to the model of strategic HRM and contextual analysis is undertaken to attempt to differentiate these from the other organizations. A comparison is also made between the findings of this research and a telephone survey that was conducted to assess the use of HRM in Leicestershire. The results of this show that a certain degree of caution should be exercised when accepting reports of organizational practices which do not involve researchers actually entering the organizations. Finally, the paper concludes that in order to get a better understanding of the situation facing these and other organizations we need to broaden our scope and consider the impact of changing economic, social and political conditions on management worker relations.     

Assessing output and productivity growth in the banking industry

This paper assesses the evolution of output and productivity in the Greek banking industry for the period 1990–2006. Three main categories of bank output were estimated based on modern theoretical approaches, while for the estimation of output and productivity (partial and total factor) we relied on the index number method (Tornqvist index). We also considered the effect of labor quality on banks’ productivity and the contribution of total factor productivity to bank output growth. Bank output and labor productivity outpaced considerably the respective GDP growth and labor productivity of the Greek economy during the period under examination. Capital and total factor productivity have also improved remarkably mainly since 1999, due to the structural changes that took place within the industry, capital (mainly IT) investments and improvement in the quality of human capital.     

Assessing the robustness of estimators when fitting Poisson inverse Gaussian models

The generalized linear mixed model (GLMM) extends classical regression analysis to non-normal, correlated response data. Because inference for GLMMs can be computationally difficult, simplifying distributional assumptions are often made. We focus on the robustness of estimators when a main component of the model, the random effects distribution, is misspecified. Results for the maximum likelihood estimators of the Poisson inverse Gaussian model are presented.     

The adoption of international best practices in a Western culture: East meets West

Contemporary organizations facing changing economic and strategic realities have considered many models of organizational performance, in particular those based on ‘actices’odels of best practice have emanated from the USA, some European countries and Japan; however, the question remains –ternational best practices be transferred to Australia or elsewhere? Since companies in Japan, in particular, have been seen as harbingers of these best practices, we compare the level of adoption in Japanese and non-Japanese companies in three Australian industries. Differences between Japanese and non-Japanese companies were more apparent in the automotive industry with only a few differences found for the information and tourism industries. The main differences between the two ownership categories were in areas of unionization and management–elations, that is, areas that may be influenced more by institutional arrangements than by cultural differences. Perhaps the most interesting finding from the comparative research was that there were relatively few differences between the Japanese and non-Japanese companies. These characteristics include: organizational structure, labour turnover, teams as part of the organizational structure, levels of training, use of ringi-style decision making, security of employment, employee welfare schemes, the use of and success with performance appraisal and performance-related pay, and a wide range of quality systems. The key pillars of Japanese management are not being transferred, and we cannot expect to see identical arrangements regarding other management practices. But the differences between Japan and western countries such as Australia are very gradually declining.     

Correlates and consequences of high involvement work practices: the role of competitive strategy

Illustrative of world-wide trends, New Zealand has undergone drastic product and labour market reforms in an attempt to stimulate economic growth and national competitiveness. Towards this goal, firms have been urged to emphasize differentiation strategies in their approach to their markets and also to become more progressive in their management of human resources. This study finds that whereas more intensive use of high involvement work practices promotes firm effectiveness, this effect depends on the competitive strategy being pursued. The use of high involvement work practices is positively associated with performance in firms competing on the basis of differentiation and shows no relationship in firms pursuing a strategy of cost leadership.     

Understanding the adoption of socially responsible supplier development practices using institutional theory: Dairy supply chains in India

Supplier development (SD) initiatives play an important role in building buyer-supplier capacities to deal with social and economic performance. The aim of this paper is to explain the motivations behind the adoption of similar SD strategies to address sustainability (particularly social issues) occurring in local supply chains of a developing country. We compare the economic and social variants of institutional theory to investigate whether efficiency or legitimacy seeking drives the adoption (and copying) of SD practices. Twelve case studies involving private and cooperative dairies were conducted in India via semi-structured interviews. Findings revealed that both private and cooperative dairies adopt similar SD practices to build supplier capabilities and improve social and economic performance of buyers and suppliers. Private dairies imitate SD practices of the cooperatives to survive the competition; i.e., economic performance is the main reason behind their isomorphism. Cooperatives, on the other hand, take up SD practices more for legitimacy and even philanthropic reasons; though also partly note the long-term economic benefits from developing the supplier community. These findings can be used both by practitioners and researchers to gain valuable insights into the reasons driving organisational isomorphism in social sustainability practices from a developing country perspective, something rarely done so far in the literature.     

Assessing the impact of green supply chain practices on firm performance in the Korean manufacturing industry

As a growing number of customers tend to view corporate social responsibility (CSR) as a key purchase decision criterion, demands for CSR including environmental sustainability have accelerated in today's business world. To meet such demands, many firms consider embracing environment-friendly business practices. However, many firms are still hesitant to implement those practices due to sceptical views about their real managerial benefits. Although the previous literature confirms the positive link between a firm's commitment to environmental sustainability and its performance, the varying degree of impact of different kinds of environment-friendly supply chain practices on the firm's operational performance is still unknown. To fill the void left by prior research, this paper aims to classify various types of green supply chain management (GSCM) practices and then assess the impact of each of these distinct types on the firm's operational performances (especially manufacturing and marketing performance). Also, this paper examines how the firm's organisational profiles such as firm size affect the particular firm's choice of GSCM practices. Our experimental results reveal that the chosen type of GSCM practices influences the firm's performance differently.     

Neither invented nor shared here: The impact and management of attitudes for the adoption of open innovation practices

Despite the massive interest in open innovation, limited attention has been expressed concerning the intra-organizational challenges in implementing it. An exemplary issue is the unwillingness of employees to undertake extra-organizational knowledge transactions in the form of negative attitudes against the sourcing of external knowledge (the not-invented-here (NIH) syndrome) and against the external exploitation of knowledge assets (the not-shared-here (NSH) syndrome). Using survey data collected from 331 firms, this article empirically assesses the theoretical assertion that the NIH and NSH syndromes have negative impacts on the adoption of inbound and outbound open innovation. Furthermore, it investigates how their effects can be reduced through competence-building programs based on the training of employees. By focusing on two attitudinal antecedents to openness, the findings offer an explanation for the problems that firms face in benefiting from inflows and outflows of knowledge and possible guidance as to how managers can disengage such attitudes.     

The adoption of HIV/AIDS policies and practices in businesses in Botswana: an exploratory study

This paper contributes to an under-researched area through an exploration of the factors motivating the adoption of HIV/AIDS policies and practices in businesses in Botswana. The focus of analysis is a developing country where HIV/AIDS is acknowledged to have had a detrimental impact on its human resources. The objective of this research was to assess whether a voluntary, non-legally binding National Policy on HIV/AIDS is an adequate motivator for the adoption of HIV/AIDS policies in businesses. The study engaged employers and managers across a number of key sectors in Botswana. The findings are explored through a theoretical lens that acknowledges institutional isomorphism and rational economic decision-making as potential motivating factors. The data indicate that the National Policy on HIV/AIDS had motivated certain businesses to adopt such policies, but a variety of other factors were also found to be involved in this process. There was, however, lack of engagement with the National Policy and with issues surrounding HIV/AIDS by a high number of the participating organisations. The research findings reveal the complexity of factors involved in adopting HIV/AIDS policies in a developing country, and therefore provide an insight in an under-researched area. They can serve as a foundation for future research on human resource management policies and practices in relation to HIV/AIDS in African economies.     

Perfect Bayesian implementation when the planner is a player

The paper contributes to the perfect Bayesian implementation problem when the planner selects an outcome after agents send a signal profile. In our problem, the planner always selects the outcomes that maximize her expected utility, given her posterior belief about the state. The paper explicitly models the problem and shows a full characterization of SCF set that can be perfect Bayesian implemented in FGP equilibrium.     

The first-order approach when the cost of effort is money

We provide sufficient conditions for the first-order approach in the principal-agent problem when the agent’s utility has the nonseparable form u(y−c(a))$u(y-c\left(a\right))$ where y$y$ is the contractual payoff and c(a)$c\left(a\right)$ is the money cost of effort. We first consider a decision-maker facing prospects which cost c(a)$c\left(a\right)$ and with distributions of returns y$y$ that depend on a$a$. The decision problem is shown to be concave if the primitive of the cdf of returns is jointly convex in a$a$ and y$y$, a condition we call Concavity of the Cumulative Quantile (CCQ) and which is satisfied by many common distributions. Next we apply CCQ to the distribution of outcomes (or their likelihood-ratio transforms) in the principal-agent problem and derive restrictions on the utility function that validate the first-order approach. We also discuss another condition, log-convexity of the distribution, and show that it allows binding limited liability constraints, which CCQ does not.     

Testing joint hypotheses when one of the alternatives is one-sided

We propose a class of statistics where the direction of one of the alternatives is incorporated. It is obtained by modifying a class of multivariate tests with elliptical confidence regions, not necessarily arising from normal-based distribution theory. The resulting statistics are easy to compute, they do not require the re-estimation of models subject to one-sided inequality restrictions, and their distributions do not require bounds-based inference. We derive explicit distribution and power functions, using them to prove some desirable properties of our class of modified tests. We then illustrate the relevance of the method by applying it to devising an improved test of random walks in autoregressive models with deterministic components. In this example, the usual alternative to a unit root is one-sided in the direction of stable roots, while deterministic components are allowed to go either way, and we show that it is beneficial to take the partially one-sided nature of the alternative into account.     

The adoption of high performance work practices in small businesses: the influence of markets,business characteristics and HR expertise

This paper explores the extent to which the adoption of high performance work practices (HPWPs) in UK small businesses with less than 50 employees is associated with the nature of the market in which the business operates, its business characteristics and its access to HR expertise. Drawing on data from the 2004 Workplace Employment Relations Survey, the analysis suggests that, where market-related factors are concerned, the uptake of HPWPs is higher in small businesses that require a highly skilled workforce but is unrelated to either the degree of market competition or the presence of large dominant customers. In terms of access to HR expertise, the analysis finds greater use of HPWPs in small businesses that have contact with external sources of HR advice via membership of business advisory networks or Investors in People (IiP) recognition. However, uptake is unrelated to the presence of personnel/HR specialists. Overall, the findings suggest that rather than depicting employment practices in small businesses as the inevitable consequence of market circumstances, encouraging greater small business involvement with business advisory networks and IiP may have the potential to increase the adoption of HPWPs in the sector.     

The conduct of the sample average when the first moment is infinite

Summary Many books about probability and statistics only mention the weak and the strong law of large numbers for samples from distributions with finite expectation. However, these laws also hold for distributions with infinite expectation and then the sample average has to go to infinity with increasing sample size. Being curious about the way in which this would happen, we simulated increasing samples (up to n= 40000) from three distributions with infinite expectation. The results were somewhat surprising at first sight, but understandable after some thought. Most statisticians, when asked, seem to expect a gradual increase of the average with the size of the sample. So did we. In general, however, this proves to be wrong and for different parent distributions different types of conduct appear from this experiment. The samples from the “absolute Cauchy”-distribution are most interesting from a practical point of view: the average takes a high jump from time to time and decreases in between. In practice it might well happen, that the observations causing the jumps would be discarded as outlying observations.
