We discuss and examine empirically a firm-level equivalent of the ancient problem of ‘tying the King’s hands’, namely how to avoid managerial intervention that is undertaken to reap private benefits but is harmful to overall value creation, that is, ‘managerial opportunism’. The link from managerial intervention to firm-level value-creation is moderated by employee motivation. Thus, interventio...

Most guidance lists managerial commitment and 'buy-in' as critical to the success of WSP implementation; yet the detail on how to generate it is lacking. This commentary discusses aspects of managerial commitment...

Resource allocation strategies in virtualized data centers have received considerable attention recently as they can have substantial impact on the energy efficiency of a data center. This led to new decision and control strategies with significant managerial impact for IT service providers. We focus on dynamic environments where virtual machines need been analyzed and used to place virtual mac...

W propose a measure of managerial ability, based on managers’ efficiency in generating revenues, which is available for a large sample of firms and outperforms existing ability measures. We find that our measure is strongly associated with manager fixed effects and that the stock price reactions to chief executive officer (CEO) turnovers are positive (negative) when we assess the outgoing CEO a...

Page Inter-reference Interval distribution, average page fault frequency (the frequency of those Instances at which an executing program requires a page of data or Instructions not In the main memory) average working set size and Inter-page fault-time (time between page fault) distribution for a simulated Working Set Replacement Algorithm for three typical programs with different sizes were mea...

Here, we examine the capability of artificial neural networks (ANNs) in sensitivity analysis of the parameters of efficiency analysis model, namely data envelopment analysis (DEA). We are mainly interested to observe the required change of a group of parameters when another group goes under a managerial change, maintaining the score of the efficiency. In other words, this methodology provides a...

We propose a novel approach to evaluating the empirical importance of individual managerial characteristics: We analyze different managerial positions (CEO and CFO) jointly and ask whether a managerial bias (overconfidence) matters for decisions under the control of the manager, but not for decisions outside the manager’s core duties. Using a new data set on CEO and CFO overconfidence, we show ...
