Screening Talent for Task Assignment: Absolute or Percentile Thresholds?

Matching talents to tasks is an important part of job design. Organizations routinely use performance thresholds to group agents by talent. We see thresholds defined both in terms of an individual's own performance (absolute value) and in terms of peer performance (percentile). Intuition suggests a preference for percentile thresholds because the resulting rank-order statistic is sufficient to assess relative talent. Yet, in the context of a task assignment problem in which the objective is to match talent with task type (using two agents and two task types), we show that absolute thresholds can dominate percentile thresholds under either of two conditions. First, flexibility in task assignment tilts the balance toward absolute thresholds. Second, performance manipulation can adversely affect the inherent advantage of percentile thresholds because they motivate agents to invest relatively more in personally costly influence activities to cast their performance in a favorable light. We examine how these results hold up when there are countably large number of agents and discuss empirical implications.     

Relative Performance Evaluation of Mutual Funds: A Non-Parametric Approach

We propose an alternative mutual fund performance index which addresses the benchmark problem and controls for economies of scale in managing mutual funds. We advance a new concept of 'return-cost' efficiency as another important element in evaluating portfolio management, in addition to the mean-variance efficiency concept. Our index based on a non-parametric estimation is shown to be similar to the Sharpe index with multiple slopes (or factors). We have shown that all fund categories, except income funds, have similar average efficiency scores after controlling for economies of scale. Most funds operate in increasing returns to scale and seem to be successful in holding mean-variance efficient portfolios, but unsuccessful in allocating transaction costs efficiently, evidenced by excessive turnovers and loads.     

EXPLAINING THE UTILIZATION OF RELATIVE PERFORMANCE EVALUATION IN LOCAL GOVERNMENT: A MULTI-THEORETICAL STUDY USING DATA FROM SWEDEN

One of the more lasting imprints that New Public Management (NPM) has made in the public sector is an increase in the popularity of performance measurement. In Sweden, performance measurement has gained popularity in the public sector, not least at the local government level with the use of relative performance evaluation (RPE). Because utilization of RPE is a decentralized and optional mode of governance, a somewhat heterogeneous practice has evolved. The aim of this paper is to examine the causes of this differentiated practice. We jointly examine economic, political and institutional/cultural explanations in order to account for the utilization of RPE. The empirical material consists of archival data and a questionnaire sent to all Swedish municipalities in late 2005. We show that RPE adoption and use partly has different antecedents and that the institutional/cultural perspective appears to have greater explanatory power than economic and political, not least as a consequence of the potential to explain decoupling and the importance of change facilitating capabilities. The investigation contributes specifically to the literature on the utilization of RPE in local governments and more generally to the literature on why and to what extent management accounting practices are utilized.

An Intertemporal CAPM Approach to Evaluate Mutual Fund Performance

Merton (1973) and Campbell (1993) have demonstrated that if an investor anticipates information shifts, he will adjust his portfolio choice today in an attempt to hedge these shifts. Exploiting these insights, we construct a new performance measure to evaluate fund managers' hedging ability. This new measure is different from two widely adopted performance evaluation measures: securities selectivity and market timing. Moreover, an econometric methodology is developed to simultaneously estimate the magnitudes of these three portfolio performance evaluation measures. The results show that mutual fund managers are on average with positive security selection and negative market timing ability. Furthermore, the mutual funds with investment style classified as Asset Allocation generally have positive hedging timing ability.     

Relative Target Setting and Cooperation

A large stream of work on relative performance evaluation highlights the benefits of using information about peer performance in contracting. In contrast, the potential costs of discouraging cooperation among peers have received much less attention. The purpose of our study is to examine how the importance of cooperation affects the use of information about peer performance in target setting, also known as relative target setting. Specifically, we use data from an industrial services company where business unit managers need to share specialized equipment and staff with their peers to manage bottlenecks in their capacity. We construct several empirical proxies for the costs and benefits of information about peer performance and examine their effects on target setting. We find robust evidence that the sensitivity of target revisions to past peer performance is higher when peer group performance has greater capacity to filter out noise but lower when the importance of cooperation among peers is greater.
