摘要：We examine the role of information-based stock trading in affecting the risk-incentive relation. By incorporating an endogenous informed trading into an optimal incentive contracting model, we analytically show that, apart from reducing incentives, a greater risk increases the level of information-based trading, which consequently enhances executive incentives and offsets the negative risk-incentive relation. We calibrate the model and find that the economic magnitude of this incentive-enhance...

摘要：We use a data set from market participants in the Taiwan Stock Exchange Capitalization Weighted Stock Index options markets to demonstrate a strong positive relationship between prior trading outcomes and subsequent risk taking. In particular, investors in this market take above-average risks in afternoon trading after morning gains. The phenomenon is prevalent in all three types of market makers' accounts and across different types of market participants. Our findings are consistent with the ...

摘要：Scientists and engineers in small firms are far more likely than their large firm counterparts to enter entrepreneurship. We label this phenomenon the small firm effect and explore its origins. In particular, we identify four classes of explanations for the small firm effect-preference sorting, ability sorting, opportunity cost, and the possibility that workers in small firms develop entrepreneurial human capital-and examine the empirical evidence for each. We find that preference sorting does...

摘要：The analytic hierarchy process (AHP) is a decision-making procedure widely used in management for establishing priorities in multicriteria decision problems. Underlying the AHP is the theory of ratio-scale measures developed in psychophysics since the middle of the last century. It is, however, well known that classical ratio-scaling approaches have several problems. We reconsider the AHP in the light of the modern theory of measurement based on the so-called separable representations recently...

摘要：Increasing globalization has created tremendous opportunities and challenges for organizations and societies. Consequently, a broad range of information technologies to better support the collaboration of diverse, and increasingly distributed, sets of participants is ever more utilized. Arguably, the success of such technology-mediated collaboration is dependent upon the quality of each individual's contributions; however, although individuals' motivations to do their best could be significant...

摘要：Using administrative data for high-priority calls in Calgary, Alberta, we estimate how ambulance travel times depend on distance. We find that a logarithmic transformation produces symmetric travel-time distributions with heavier tails than those of a normal distribution. Guided by nonparametric estimates of the median and coefficient of variation, we demonstrate that a previously proposed model for mean fire engine travel times is a valid and useful description of median ambulance travel time...
