Measuring Productivity from Vertically Integrated Sectors

There are many ways to measure productivity. The choice will depend on the suitability of each index to the main purpose the researcher has in mind. Whenever we are interested in 'competitiveness', the proper measure will be the inverse of the total labour embodied in one unit of final product; or, what amounts to the same, the labour employed in the vertically integrated sector corresponding to each final good. A weighted mean of these yields an index of aggregate productivity suitable for measuring social welfare. Another index of aggregate productivity (this one related to the profit rate and potential growth) coincides with the inverse of the maximum eigenvalue of the 'socio-technical matrix'. These indices are computed for the Spanish economy and compared with more conventional ones.     

Forecasting With the Standardized Self‐Perturbed Kalman Filter

We propose and study the finite‐sample properties of a modified version of the self‐perturbed Kalman filter of Park and Jun (Electronics Letters 1992; 28 : 558–559) for the online estimation of models subject to parameter instability. The perturbation term in the updating equation of the state covariance matrix is weighted by the estimate of the measurement error variance. This avoids the calibration of a design parameter as the perturbation term is scaled by the amount of uncertainty in the data. It is shown by Monte Carlo simulations that this perturbation method is associated with a good tracking of the dynamics of the parameters compared to other online algorithms and to classical and Bayesian methods. The standardized self‐perturbed Kalman filter is adopted to forecast the equity premium on the S&P 500 index under several model specifications, and determines the extent to which realized variance can be used to predict excess returns.

Are CSR Disclosures Value Relevant? Cross-Country Evidence

Using proprietary data that rate corporate social responsibility (CSR) disclosures of firms in 21 countries, this study examines how the strength of nation-level institutions affects the extent of CSR disclosures. We then examine the valuation implications of CSR disclosures and consider how the relation between CSR disclosures and firm value varies across countries. In contrast to prior studies, we separate CSR disclosures into an expected and unexpected portion where the unexpected portion is a proxy for the incremental information contained in CSR disclosures. We observe a positive relation between unexpected CSR disclosure and firm value measured by Tobin's Q. We also find that, while countries with strong nation-level institutions promote more CSR disclosures, the valuation of a unit increase in unexpected CSR disclosures is higher when nation-level institutions are weak.     

Exploring the power dimensions of the human resource function

While a large body of literature has investigated the content of human resource management (HRM) practices, this research explores the process through which the HRM function impacts on organisational performance. Specifically, the research explores the reasons for the success or failure of HRM initiatives that have been associated with organisational outcomes and classifies the reasons as dimensions of HRM power. Based on 26 interviews conducted in Australia with senior HRM executives, top management team (TMT) executives and two management consultants, we found that, in order to contribute to organisational performance, HRM professionals can effectively utilise three dimensions of power, namely power of resources, power of processes and power of meaning. The findings offer new insights to the relationship between dimensions of HRM power and organisational performance.     

Trajectories for Modernizing Local Governance: Revisiting the Flanders Case

Local government plays a central but altering role in local governance. Together with the shift from a night-watchman state to a welfare state , the models of governance provision changed. Government itself became larger and more scattered throughout the local community. Moreover, government was no longer the only governance provider. Many actors were involved in governance with a diversity of steering relations. In our time, governance continues to change. What are the emerging models of local governance today? After sorting out some terminological and methodological issues, we describe four emerging ideal-type models (i.e. the holding model , the autonomous networks model , the implementation model and the reintegration model ), based on four societal scenarios (i.e. triumphant markets , hundred flowers , creative societies and turbulent neighbourhoods ). The models represent four possible local governance futures. Next, the models are applied on two management issues: organizational structure and financial management. Finally, some embryonic evidence is given on the emergence of the models.     

The inside effects of a strong external employer brand: how external perceptions can influence organizational absenteeism rates

In this study, we invoke a social identity and job resources perspective to investigate the impact of an organization’s internal and external employer brand images on employee absenteeism. Specifically, using workforce samples of 56 Belgian companies (n = 12670) and a second independent study sample (n = 4461), we assess the relative importance of the internal employer brand image (i.e. employee perceptions) and the external employer brand image (i.e. non-employee perceptions) in predicting the absenteeism rate in these organizations. Results show that corporate absenteeism decreases as internal (employee) views and external (non-employee) views of the organization decline. Results further show that the external employer brand image may be a more important driver of absenteeism than the internal employer brand image. Such results highlight that an organization’s external image may be a strong antecedent of important internal organizational behavior outcomes.     

Bouncing back from a sudden-onset extreme event: exploring retail enterprises’ resilience capacity

ABSTRACT

A feature of recent decades has been the sudden and unexpected occurrence of catastrophic events seriously affecting people and territories. From an economic viewpoint, this has led scholars to pay increasing attention to factors and determinants taking enterprises face-to-face with extreme and catastrophic events, through the resilience lens. In this context, this study aims to contribute to the literature on resilience to natural disasters which is currently still limited in the business and management fields, both theoretically and empirically. This is particularly true as regards retailing, despite the key role played by retail in the aftermath and recovery periods following on from sudden-onset extreme events such as earthquakes.

The 2012 Emilia earthquake is a case in point with which to explore small retail enterprises’ resilience to sudden-onset disasters. Specifically, our empirical research consisted of administering a structured questionnaire to a sample of small retail enterprises which experienced an earthquake. The unit of analysis adopted was the retail enterprise. Data was processed applying Covariance-Based Structural Equation Modeling (CB-SEM). The structural model aims to verify the impact of sales capabilities, market orientation and networking capabilities on the resilience capacity of retail enterprises affected by an extreme event, controlling for certain financial indicators such as suppliers’ payment timeframes and the use of debt capital, as well as respondent age and gender. The findings show that all the antecedents analysed exert a significant and positive effect on small retail enterprises’ resilience capacity and ability to bounce back from natural disasters. Moreover, suppliers’ payment timeframes showed a direct relationship with retail enterprises’ resilience capacity, with lower use of debt capital equalling higher retail business resilience. Age and gender do not exert any significant effect. Scientific, managerial and public policy implications are derived.

Environmental sustainability in container transport: the attitudes of shippers and forwarders

The transport sector accounts for 25% of the global CO₂ emissions. All firms in the transport industry share a responsibility for this environmental impact. This paper explores, as one of the first, the attitude of both shippers and forwarders, as the main purchasers of transport services, towards environmental sustainability in the sourcing of transport services. Based on a literature review we develop several hypotheses and test those through a survey among shippers and forwarders in the Netherlands. We conclude that shippers focus more on sustainability than forwarders, the size of shippers has a positive influence on the demand for transparency of the environmental performance, explicit sustainability targets have a positive influence on the demand for sustainable solutions and the vast majority of shippers and forwarders expect an increased importance of sustainable purchasing.     

Causality Rules: Performance Feedback on Hierarchically Related Goals and Capital Investment Variability

We extend March and Simon’s (1958) analysis of strategic decisions by distinguishing between two rules for allocating attention – priority versus causality. We develop theory concerning causality rules which have been largely overlooked in prior literature. Specifically, we examine how performance feedback on the intermediate productivity goal and the higher‐order profitability goal independently and jointly influence the variability of firm capital investments. Panel analysis of 2,477 Spanish manufacturing firms reveals that these goals jointly affect the variability of capital investments through both priority and causality attention rules. Our study provides new insights on how firms handle multiple goals, deconstruct performance feedback, and cope with the attentional constraints of bounded rationality.
