The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe ...

This paper proposes an alternative data envelopment analysis for assessing the operational performance of 46 international tourist hotels (ITHs) in Taiwan over the period 1997-2002. This study is the first research that combines the discriminant power of a slack-based measure and the dynamic view of window analysis in applying DEA. It is shown that the trend of mean managerial efficiency is inc...

To the Editor, Arakelian et al. [1] studied qualitatively surgical teams' perceptions of operating room (OR) efficiency. Although they state that 'the lack of studies of this kind rendered it difficult to compare the results with those of others', psychological studies complement the authors' organizational (sociological) investigations [1, 2]. OR efficiency is influenced by team members' biase...

From 1988 to 2003, the average change in managerial ownership is significantly negative every year for American firms. We find that managers are more likely to significantly decrease their ownership when their firms are performing well, but not more likely to increase their ownership when their firms have poor performance. Because investors learn about the total change in managerial ownership w...

Data Envelopment Analysis (DEA) is a linear programming based technique that was developed to evaluate relative efficiency of nonprofit and public sector Decision Making Units (DMU's) that use multiple inputs to produce multiple outputs. In this study, DEA is evaluated and tested for use as a managerial audit tool to identify and measure inefficiencies among a set of DI'IU's. Based on three app...

Abstract—In this paper we extend CSL (Continuous Stochastic Logic) with an expected time and an expected reward operator, both of which are parameterized by a random terminal time. With the help of such operators we can state for example that the expected sojourn time in a set of goal states within some generally distributed delay is at most (at least) some time threshold. In addition, certain ...
