The virtuous circle of human resource investments: A precrisis and postcrisis analysis

We propose a dynamic model of positive feedback between human resource (HR) investments and companies' economic performance. The model assumes that HR investment increases profitability through labor productivity and, in turn, profitability improves HR investment through organizational slack. Based on data from a sample of 2,497 industrial companies over a 7‐year period (2005–2011), longitudinal analysis corroborates the existence of a two‐way relationship between HR investment and profitability over time. However, the emergence of an economic crisis weakens this feedback, identifying the effect of organizational slack on HR investment as the weakest causal chain link. In a postcrisis period, HR investment is not such a high priority for managers.

Incentives and teacher effort

Few would contest that teachers are a very important determinant of how much students learn in school, and how to improve teacher performance has been the focus of lively policy debate in both rich and poor countries. This paper examines how teacher incentives, both pecuniary and non‐pecuniary, correlate with teacher effort. Using school survey data from Lao PDR, we estimate measures of teacher effort, including the number of hours that teachers spend preparing for classes and teacher provision of private tutoring outside of class hours, which are not the typical measures used in previous research. Estimation results fit well under the standard labour supply framework and indicate that greater teacher effort is associated with non‐pecuniary incentives such as more teacher autonomy over teaching materials and monitoring as measured by the existence of an active parent – teacher association and the ability of school principals to dismiss teachers. Methodologically, this paper provides a detailed derivation of a simultaneous OLS‐probit model with school random effects that can jointly estimate teacher work hours and tutoring provision.     

A model to evaluate transient industry effects

In this paper we present a model to evaluate transient industry effects, that is, the impact of business cycles on the industry. While the importance of the economic cycle for industry and firm performance is widely recognized, we do not know much about how much the business cycle influences industry activity. The aim of this paper is to present a method that helps to understand the relationship between the business cycle and an industry's level of activity. Copyright © 2008 John Wiley & Sons, Ltd.     

Strategic HRM in China: Configurations and competitive advantage

The strategic HR literature suggests that a firm will perform better through internal appropriate fit among HRM practices (the configuration fit) and through external appropriate fit between a firm's HRM practices and business strategy. The present study adopts a configuration approach to identify unique patterns of HR practices and business strategy that are posited to be maximally effective. The proposed relationships were empirically tested by surveying with a sample of 241 business firms in Guangzhou, South China, to find out the extent that four HR configurations could be successfully adopted in the Chinese context. The results revealed that HR configurations are significantly related to effect in predicting overall outcome performance and turnover, but not significantly related to effect on sales growth and profit growth rates. Research findings showed not only competitive strategies are significantly related to effect on HR configurations. The results also showed significant interaction effects between HR configurations and business strategy in their effect on profit and sales growth. These results further extended support for a contingency perspective in strategic HRM to the Chinese context, with significant practical implications for managing HRM in China. © 2008 Wiley Periodicals, Inc.

The Neuer Markt as an institution of creation and destruction

The market for publicly traded equity is the heart of a modern capitalist system. In particular, the market for newly listed firms is in turn a bellwether for the public equity market because the entry gives firms expanded access to capital, allowing them to emerge and grow. On the other hand, stock markets also serve as an institution to reallocate productive resources from non-surviving to surviving firms. We describe the Neuer Markt—a special segment of the Frankfurt Stock Exchange in Germany—as an institution to foster the creation of new firms and their destruction.

The Stambaugh bias in panel predictive regressions

This paper analyzes predictive regressions in a panel data setting. The standard fixed effects estimator suffers from a small sample bias, which is the analogue of the Stambaugh bias in time-series predictive regressions. Monte Carlo evidence shows that the bias and resulting size distortions can be severe. A new bias-corrected estimator is proposed, which is shown to work well in finite samples and to lead to approximately normally distributed t-statistics. Overall, the results show that the econometric issues associated with predictive regressions when using time-series data to a large extent also carry over to the panel case. The results are illustrated with an application to predictability in international stock indices.     

Modelling the Ecological Comorbidity of Acute Respiratory Infection,Diarrhoea and Stunting among Children Under the Age of 5 Years in Somalia

The aim of this study was to assess spatial co‐occurrence of acute respiratory infections (ARI), diarrhoea and stunting among children of the age between 6 and 59 months in Somalia. Data were obtained from routine biannual nutrition surveys conducted by the Food and Agriculture Organization 2007–2010. A Bayesian hierarchical geostatistical shared component model was fitted to the residual spatial components of the three health conditions. Risk maps of the common spatial effects at 1×1 km resolution were derived. The empirical correlations of the enumeration area proportion were 0.37, 0.63 and 0.66 for ARI and stunting, diarrhoea and stunting and ARI and diarrhoea, respectively. Spatially, the posterior residual effects ranged 0.03–20.98, 0.16–6.37 and 0.08–9.66 for shared component between ARI and stunting, diarrhoea and stunting and ARI and diarrhoea, respectively. The analysis showed clearly that the spatial shared component between ARI, diarrhoea and stunting was higher in the southern part of the country. Interventions aimed at controlling and mitigating the adverse effects of these three childhood health conditions should focus on their common putative risk factors, particularly in the South in Somalia.
