The frequency of visiting a doctor: Is the decision to go independent of the frequency?

In his analysis of the effects of the reform of the German healthcare system, Winkelmann (Journal of Applied Econometrics 2004; 19 : 455–472) investigates the number of doctor visits. He makes a distinction between the decision to go to a physician and the number of times the physician is visited in the observed time period. Winkelmann finds that there is no correlation between both decisions. This result appears to be far from straightforward since the primary driving force in both decisions will be the health of the patient. From this perspective a significant correlation is expected. In this paper, I first replicate part of Winkelmann's research. I then set out to analyse whether the zero correlation is actually true or comes from the way the relation between both decisions is modelled. My empirical analysis confirms the latter, but nevertheless also corroborates Winkelmann's main conclusions on the relevance of the explanatory variables used in his investigation.

Farewell to the salaryman? The changing roles and work of middle managers in Japan

The 1990s and 2000s witnessed significant organizational change in Japanese firms and accompanying readjustments to the employment system. Such changes potentially have major implications for middle managers, or salarymen, in Japanese corporations. A survey of human resource managers and middle managers in eight medium sized Japanese organizations pointed to fairly significant, if not radical, change. This did, indeed, impact upon middle managers in those organizations. While the middle managers felt reasonably secure in their jobs, the nature of their jobs had reportedly changed, with a greater range of tasks, work intensification, longer hours, greater stress, more accountability, and a worsening work–life balance.     

A Point Processes approach to bicycle sharing systems’ design and management

Public bicycle systems have attracted a great deal of attention in recent years. The success of this service heavily depends on the topology of the city and on the locations of bike stations in relation to potential demand. In fact, it is primarily important that users find bike stations in convenient locations, sufficiently close both to the origins of their trips and to their destinations, and that each rental station guarantees the availability both of enough bicycles and of enough empty docking slots.This paper proposes a point processes approach to the study of bike-sharing systems, allowing us to quantify and control parameters having a key role in decisions both of strategic and operational type.Differently from previous studies, the point processes approach catches both the interdependence among the stations and the links between spatial and time aspects of the problem.The application of point processes, in particular spatial mixed Poisson processes, to this field requires the statement and proof of an invariance property of such processes under stochastic dependent transformations, that may be of interest also from a theoretical point of view.     

Are high-performance work practices related to individually perceived stress? A job demands-resources perspective

This study investigates the relationship between high-performance work practices (HPWP) and individually perceived stress. Contrary to most past research, which evaluates HPWPs positively, this study emphasizes the potential downside of HPWPs, and suggests that some HPWPs are more strongly associated with enhanced stress than others. Drawing on the job demands-resources model, we differentiate between challenge demand HPWPs (i.e., performance evaluation systems, continuing education) and job resource HPWPs (i.e., flexible working hours, participation in decision-making). We then analyze 197 employees and their work environments, demonstrating that there is a positive relationship between challenge demands and individual stress among employees. Contrary to what we predicted, no empirical evidence indicates that the two analyzed job resources relate negatively to stress.     

What happened to the work I was doing? Sociomateriality and cognitive tensions in technology work

In recent times, there is growing recognition that the implications of technology are not a given; they result from how the social and technical interact to redefine work-related expectations. The sociomateriality lens highlights the inseparable and relational aspects of the social and technological systems. We draw upon sociomateriality to highlight cognitive tensions that technology work generates through two case studies. Based on these insights, we provide suggestions to practitioners to mindfully examine their digital transformation efforts and identify plans to mitigate the tensions.     

Whistle while you work? A review of the effects of music in the workplace

The effects of music on human performance have been studied across many disciplines. Music has been shown to impact task performance, organizational citizenship behaviors, and learning (i.e., training), but the implications of the study of music in the workplace have not yet been fully realized. Therefore, we conduct an interdisciplinary review of research on music relevant to the field of management. We also offer a solution to the lack of theoretical grounding in previous work by applying activation theory to understand the effects of music in the workplace. Taken together, the literature shows that music works through the mediator of mood and emotion. Findings also illustrate the consequences of extraversion, task complexity, and listening autonomy in relation to individual affective reactions to music. While the evidence suggests music may potentially have significant value in the workplace, more research is needed to understand how music might be effectively utilized by organizations.     

Is the small-ball strategy effective in winning games? A stochastic frontier production approach

Since the Japanese National Baseball team won the inaugural World Baseball Classic, “small ball” has been accepted, at least by the media, as a mainstream form of baseball management in Korea. Small ball refers to a manager’s active intervention or strategy implementation in baseball games. In general, the frequency of managers’ orders for play actions such as a sacrifice bunt is higher in Asian baseball than in North American baseball. This paper attempts to statistically test the hypothesis that small ball is effective in winning games by using data from Korean baseball. The panel data analysis of a stochastic production frontier model presents somewhat mixed empirical results, but the overall evidence suggests that small ball actually has detrimental effects on the number of runs scored.     

Is God in the details? A reexamination of the role of religion in economic growth

Barro and McCleary (2003, Religion and economic growth across countries. American Journal of Sociology 68 : 760–781) is a key research contribution in the new literature exploring the macroeconomic effects of religious beliefs. This paper represents an effort to evaluate the strength of their claims. We evaluate their results in terms of replicability and robustness. Overall, their analysis generally meets the standard of statistical replicability, though not perfectly. On the other hand, we do not find that their results are robust to changes in their baseline statistical specification. When model‐averaging methods are employed to integrate information across alternative statistical specifications, little evidence survives that religious variables help to predict cross‐country income differences.

Does the professionalism of management practices in nonprofits and for-profits affect job satisfaction?

This paper examines workers' satisfaction related to the level of professionalism of managerial practices in the French services sector. The data used are from the original survey conducted by the French Institute for Demographic Research and include both workers' responses on their satisfaction level, individual characteristics, job conditions, etc. and employers' responses on managerial practices implemented. We construct an index of workers' overall satisfaction and an index of ‘managerial professionalism’. In our model of workers' overall job satisfaction, the index of managerial practices is treated as an endogenous variable using two-stage least squares regressions. We show that the index of managerial practices is strongly and positively associated with workers' overall workplace satisfaction. Overall workplace satisfaction is found to be strongly associated with wages and individuals' perceptions about work environment. Finally, working in nonprofits is positively associated with greater overall job satisfaction.     

A spatial dominance approach to evaluate the performance of stocks and bonds: Does the investment horizon matter?

The common advice by practitioners is to allocate a greater proportion of stocks for long-term investors than for short-term investors. However, part of the academic literature disagrees with this advice. We use a spatial dominance test which is suited for comparing alternative investments for a given time horizon. Using daily data for the US from 1962 to 2012, we test for dominance of cumulative returns series for stocks versus bonds at different investment horizons from 1 to 15 years. We find evidence that bonds second order spatially dominate stocks for horizons from 1 to 4 years. In contrast, for horizons of 6 years and longer, we find evidence that stocks dominate bonds. The conclusion that bonds dominate stocks at short horizons, while stocks dominate bonds at long horizons is consistent across different periods and international markets. When different portfolios of stocks and bonds are compared, we find that for long investment horizons only those portfolios with a sufficiently high proportion of stocks are efficient in the sense of spatial dominance.     

A PCA–DEA approach to measure the quality of life in Estonian counties

This paper investigates the application of a PCA–DEA model to assess the quality of life (QOL) scores in Estonian counties and analyses the model's results. The dataset is a balanced panel of 15 Estonian counties covering the period from 2000 to 2011. We consider a PCA–DEA model as an alternative method to estimate and predict QOL scores and rankings of Estonian counties. The method consists of a two-stage analysis that begins with a principal component analysis. In the second stage, the standard DEA is used. The results from the conventional DEA model and the PCA–DEA model are compared and discussed. A comparison of the methodologies demonstrates that a PCA–DEA model provides a powerful tool for performance ranking. The rankings of Estonian counties using QOL scores for different model specifications are presented. Finally, the QOL ranking of Estonian counties is revised using PCA–DEA.     

Linking work–family conflict to job attitudes: the mediating role of social exchange relationships

This study uses social exchange theory to develop a model of the processes linking work–family conflict to job attitudes. This model was tested on a sample of 236 employees in Taiwan's high-technology industry. The regression results revealed that perceived organizational support and leader–member exchange fully mediated the influence of work–family conflict on intentions to quit and affective organizational commitment, and partially mediated work–family conflict's influence on job satisfaction. The implications are discussed in this article.     

Workaholism versus work engagement and job crafting: What is the role of self‐management strategies?

Job crafting refers to the proactive actions employees take to redesign their jobs in order to get a better fit with their competencies, expectations, and wishes. So far, little is known about job crafting's underlying mechanisms. In this study, we examine how two different states of affective well‐being (workaholism and work engagement) relate to job crafting 3 months later and how these well‐being states steer different self‐management behaviours, which ultimately lead to job crafting. Structural equation modelling on a heterogeneous sample (N = 287) revealed that work engagement and workaholism both relate to expansive job crafting through different self‐management strategies. Work engagement relates to challenge and resource seeking via self‐goal setting and self‐observation strategies, whereas workaholism associates with challenge and resource seeking only through self‐goal setting. In addition, the results show a strong relationship between workaholism and self‐punishment. Altogether, the findings suggest that self‐management strategies can function as an explanatory mechanism for different job crafting behaviours.

What is the meaning of ‘talent’ in the world of work?

The ongoing confusion about the meaning of ‘talent’ within the world of work is hindering the establishment of widely accepted talent management theories and practices. The aim of this paper is to contribute to the literature on talent management by offering an in-depth review of the talent concept within the specific context of the world of work, and proposing a framework for its conceptualization. We group different theoretical approaches to talent into ‘object’ (i.e., talent as natural ability; talent as mastery; talent as commitment; talent as fit) versus ‘subject’ approaches (i.e., talent as all people; talent as some people) and identify dynamics existing within and between them, as well as implications for talent management theory and practice. Finally, we discuss different avenues for further research aimed at developing the talent—and consequently, the talent management—construct further.     

Is all turnover intent the same? Exploring future job preference and environmental considerations

This study approaches turnover intent in a novel way by incorporating both environmental and internal organizational factors together to create a more nuanced view of what drives turnover. The analytical focus is on senior-level employees in four agencies within the US Department of Health and Human Services. The findings show that internal organizational factors partially explain decisions to change jobs, but agency and time differences remain even after controlling for those factors. It also finds that the decision to leave government is driven by different factors than the decision to move to other jobs within government.     

Is High Inflation Here to Stay in the UK?

The first decade of monetary policy independence saw a period of low and stable inflation, but over the past six years this has given way to higher, and more volatile, inflation. The increase in inflation rates has both external and domestic origins. Higher commodity prices, in particular food, and rising prices of manufactured goods imported from emerging markets have been important. In both cases the sharp depreciation of the pound in the aftermath of the financial crisis has compounded the impact on the UK. There has also been a marked step upwards in domestic inflationary pressures which has largely come from administered & regulated prices, such as domestic energy prices and university tuition fees. These categories account for just 10% of the inflation basket, but over the past six years they have contributed 0.9ppts to an average CPI inflation rate of 3.1%…     

Is the causal nexus of energy utilization and economic growth asymmetric in the US?

This paper re-examines the causal nexus of energy utilization and GDP per capita in the US. The novelty of the paper is to allow for asymmetry in causality by using a new test introduced by Hatemi-J (forthcoming). A bootstrap procedure is used with leveraged corrections that perform more accurately when the statistical assumptions for validity of asymptotic distributions are not fulfilled. This is especially the case for sample sizes as in the current paper. The estimation results reveal strongly that a negative energy consumption shock will cause a negative shock in the output per capita. That is, if the energy utilization per capita decreases then the output per capita will also decrease. Surprisingly, such a causal impact for positive shocks is not found. These empirical results might indicate that there is an optimal quantity of energy in the US that needs to be consumed as otherwise the economic growth will suffer. However, the consumption of energy beyond that optimal quantity will not necessarily result in an enhanced rate of economic growth.
