Guidelines for choosing between multi-item and single-item scales for construct measurement: a predictive validity perspective

Establishing predictive validity of measures is a major concern in marketing research. This paper investigates the conditions favoring the use of single items versus multi-item scales in terms of predictive validity. A series of complementary studies reveals that the predictive validity of single items varies considerably across different (concrete) constructs and stimuli objects. In an attempt to explain the observed instability, a comprehensive simulation study is conducted aimed at identifying the influence of different factors on the predictive validity of single versus multi-item measures. These include the average inter-item correlations in the predictor and criterion constructs, the number of items measuring these constructs, as well as the correlation patterns of multiple and single items between the predictor and criterion constructs. The simulation results show that, under most conditions typically encountered in practical applications, multi-item scales clearly outperform single items in terms of predictive validity. Only under very specific conditions do single items perform equally well as multi-item scales. Therefore, the use of single-item measures in empirical research should be approached with caution, and the use of such measures should be limited to special circumstances.     

A resource-based view of human resource management and organizational capabilities development

The aim of this research work was to analyse the role of human resource management in the development of organizational capabilities and its influence on the firm's performance from a resource-based view. Our results, from empirical research on a nation-wide sample of Spanish savings banks, suggest that human resource decisions, integrated in a human resource system, have an important influence on the development of organizational capabilities and on the firm's performance.     

Management Changes,Reputation, and “Big Bath”—Earnings Management

We study the effects of managerial turnover on earnings management activities in a model in which managers care about their external reputation. We develop an overlapping generations model showing that both outgoing and incoming managers bias reported earnings such that typically very low returns are reported in the first period after a manager has been replaced. Outgoing managers shift earnings forward to their last period in office as they will not benefit from earnings realized after that. Incoming managers can have an incentive to shift earnings to the second period in office as reported earnings will, immediately after a management change, only be partly attributed to their own ability. Deferred compensation can reduce incentives for earnings management.     

Adaptation and Performance in New Businesses: Understanding the Moderating Effects of Independence and Industry

New ventures as well as new business units experience significant difficulties in finding a viable business model. They often need to adapt their initial business model due to the presence of uncertainty and ambiguity. Technology-based companies are confronted with particularly high degrees of uncertainty and ambiguity. We hypothesize that adaptation is crucial for the performance (measured as survival) of these businesses, but that this effect is moderated by the (in)dependence of the new technology-based business and by the industry in which it is active. We test the adaptation-performance hypothesis through a survival analysis of a sample of 117 independent new ventures and business units. Our findings suggest that adaptation is beneficial in less mature, capital-intensive and high-velocity industries but not so in more mature, stable industries. Also, adaptation reduces failure rates in dependent business units as compared to independent ventures.     

The development of contract research organisations in Sweden: health care,privatisation and neo‐liberalism

This paper examines changes in local working conditions instigated by the development of contract research organisations in pharmaceutical development. These developments are seen as occurring in the context of Sweden's ‘circumscribed neoliberalization’. It is shown how staff remain ambivalent about the shifts of location and identity that these developments imply.     

Matching As An Econometric Evaluation Estimator

This paper develops the method of matching as an econometric evaluation estimator. A rigorous distribution theory for kernel-based matching is presented. The method of matching is extended to more general conditions than the ones assumed in the statistical literature on the topic. We focus on the method of propensity score matching and show that it is not necessarily better, in the sense of reducing the variance of the resulting estimator, to use the propensity score method even if propensity score is known. We extend the statistical literature on the propensity score by considering the case when it is estimated both parametrically and nonparametrically. We examine the benefits of separability and exclusion restrictions in improving the efficiency of the estimator. Our methods also apply to the econometric selection bias estimator.     

Predicting market orientation through internal market orientation as culture and behaviour: an empirical application in Spanish hotels

The aim of this study is to analyse how the internal market orientation, considered from a dual perspective, cultural and behavioural, affects the development of external market-oriented behaviours by improving the attitudinal results (affective commitment and job satisfaction) of the internal customers. An empirical study was carried out, based on the perceptions of 68 managers and 296 supervisors at four- and five-star hotels in Gran Canaria (Canary Islands, Spain). The findings show that (1) the internal market orientation (IMO) has a positive influence on the effective development of market orientation behaviours in managers and supervisors; (2) the IMO has a positive influence on the affective commitment and job satisfaction of hotel managers, but not supervisors; and (3) greater affective commitment and job satisfaction have no significant effect on market orientation behaviours in hotel managers or in supervisors. Based on the study results, the paper concludes with a discussion and implications for practitioners.     

The Effects of Corporate Governance on the Informativeness of Earnings

This study draws upon prior research on corporate governance and examines whether the informativeness of earnings, proxied by the earnings response coefficient varies with the percentage of outside independent directors serving on the board, the absence of CEO duality, and the presence of independent audit (AUDC), compensation (COMC), and nominating (NOMC) committees. The results suggest a positive association between the proportion of outside independent directors serving on firm’s boards and earnings informativeness. However, the results do not suggest an association between non-CEO duality, or independent AUDC, COMC, and NOMC and earnings informativeness.
