This paper studies how to assign “monitors” to productive agents in order to generate signals about the agents' performance that are most useful from a contracting perspective. We show that if signals generated by the same monitor are negatively (positively) correlated, then the optimal monitoring assignment will be “focused” (“dispersed”). This holds because dispersed monitoring allows the firm to better utilize relative performance evaluation. On the other hand, if each monitor communicates only an aggregated signal to the principal, then focused monitoring is always optimal since aggregation undermines relative performance evaluation. We also study team‐based compensation and randomized monitoring assignments. In particular, we show that the firm can gain from randomizing the monitoring assignment, compared with the optimal linear deterministic contract. Furthermore, under randomization, the conditional expected utility for the agent is higher when the agent is not monitored compared with the case where the agent is monitored. That is, the chance of being monitored serves as a “stick” rather than a “carrot”.  相似文献

Corporate planning systems that, when developed, promised to solved all corporate ills have fallen far short of management expectations. The major reason for this is a lack of communication which results in different problems being solved by planners than those that management views as most important. The author explains how Planning Trees can help focus both the CEO and the planners on the same important issues and defined the key assumptions behind those issues.  相似文献

The aim of this paper is to investigate the existence and nature of seasonality (deterministic or stochastic) in tanker freight markets and measure and compare it across sub-sectors and under different market conditions (expansionary and contractionary) for the period January 1978 to December 1996. The existence of stochastic seasonality is rejected for all freight series while results on deterministic seasonality indicate increases in rates in November and December and decreases in rates from January to April. Seasonality is found to be varying across markets depending on vessel size and market condition. Seasonality comparisons under different market conditions, an issue investigated for the first time in the econometrics literature using Markov Switching models, reveal that seasonal rate movements are more pronounced when the market is recovering compared to smaller changes when the market is falling. This is well in line with the low and high elasticity of supply expected in expansionary and contractionary periods of shipping markets. The results have implications for tactical shipping operations such as budget planning, timing of dry-docking, vessel speed adjustments and repositioning. As expected, the out-of-sample forecasting performance of these Markov Regime Switching models is lacking somewhat, a result which is thought to be a consequence of having to predict ‘states’ simultaneously with mean values.  相似文献

Dividend Changes and Future Profitability   总被引:9,自引:0,他引:9  
We investigate the relation between dividend changes and future profitability, measured in terms of either future earnings or future abnormal earnings. Supporting "the information content of dividends hypothesis," we find that dividend changes provide information about the level of profitability in subsequent years, incremental to market and accounting data. We also document that dividend changes are positively related to earnings changes in each of the two years after the dividend change.  相似文献

We find that the sign of the correlation between institutional ownership and volatility depends on the firm’s dividend policy: institutional ownership is negatively (positively) related to volatility among non-dividend (dividend) paying stocks. The empirical results are consistent with an interaction between institutional preference for low volatility and the tendency of higher levels of institutional ownership to increase volatility through their trading behavior. This result is robust to many control variables and possible endogeneity concerns. Supporting our conjecture that institutions herd on dividend signals we find that the correlation between turnover and institutional ownership is higher for dividend paying stocks, and that the positive correlation between turnover and institutional ownership is higher on dividend declaration days. Finally, we also find that the level of institutional ownership drops following an increase in volatility for both dividend payers and non-payers, and that volatility rises following increased institutional ownership for dividend paying stocks.  相似文献

We study two-person extensive form games, or “matches,” in which the only possible outcomes (if the game terminates) are that one player or the other is declared the winner. The winner of the match is determined by the winning of points, in “point games.” We call these matches binary Markov games. We show that if a simple monotonicity condition is satisfied, then (a) it is a Nash equilibrium of the match for the players, at each point, to play a Nash equilibrium of the point game; (b) it is a minimax behavior strategy in the match for a player to play minimax in each point game; and (c) when the point games all have unique Nash equilibria, the only Nash equilibrium of the binary Markov game consists of minimax play at each point. An application to tennis is provided.  相似文献

Post-World War II intrametropolitan dispersion of industry has been well documented in the literature on contemporary suburbanization. There has, however, been no empirical research conducted to determine the effect of the restructured metropolitan economy upon labor force participation rates of suburban residents, especially of suburban married women. The purpose of this study is to fill this research gap. The hypothesis tested is that increased employment opportunities in the suburbs will increase labor force participation of suburban married women, ceteris paribus . The research results show the hypothesized relationship to be correct. The variable developed in this study and used as a proxy for the degree of intrametropolitan industrial dispersion is statistically significant, albeit a bit weak, in explaining intersuburban variation in labor force participation rates of married women, husband present. Other variables (such as median school years completed) included in more traditional non-spatially oriented labor force behavior models are statistically insignificant in explaining areal variation in participation rates. The findings point up the necessity of recognizing the spatial complexities of the urban economy.  相似文献
