摘要：A multiperiod stochastic optimization model is formulated for a land owner who can speculate between investing harvesting income in financial assets and postponing harvesting. This paper demonstrates the benefits from using a multiperiod model, the effects of cointegration on optimal portfolio, and the differences between the timber harvesting model and the standard financial portfolio optimisation model. The demonstrations are made partly by using a real Finnish forest and price data, and par...

摘要：This paper presents evidence that the willingness to punish an unfair action is sensitive to whether this action was preceded by a deceptive message. One player first senda a message indicating an intended play, which is either favorable or unfavorable to the other player in the game. After the message, the sender, and the receiver play a simultaneous 2 x 2 game, in which the sender may or may not play according to his message. Outcome cells may, hence, be reached following true or false messa...

摘要：In this paper, we develop two models for the valuation-of information technology (IT) investment projects using the real options approach. The IT investment projects discussed in this paper are categorized into development and acquisition projects, depending upon the time it takes to start benefiting from the IT asset once the decision to invest has been taken. The models account for uncertainty both in the costs and benefits associated with the investment opportunity. Our stochastic cost func...

摘要：Communication technologies support virtual R&D groups by enabling immediate and frequent interaction of their geographically-distributed members. Performance of members in such groups has yet to be studied longitudinally. A model proposes not only direct effects of. functional role, status, and communication role on individual performance, but also indirect effects through individual centrality. Social network analysis was performed on e-mail samples from two time periods separated by four yea...

摘要：A widespread practice, particularly in public-sector procurement and dispersal, is to subsidize a class of competitors believed to be at an economic disadvantage. Arguments for such policies vary, but they typically assume that benefits of subsidization must be large enough to outweigh a presumed economic cost of the subsidy. When disadvantaged competitors compete in auctions, the subsidy serves to. make them more competitive rivals. Other bidders rationally respond by bidding more aggressivel...

摘要：Many organizational learning studies have an implicit assumption that the learning rate is maximized through specialization: the more an individual or organization focuses on a particular task, the faster it will improve. However, through contrasting the various learning process theories described in the research on organizational, group, and individual learning, we develop a set of competing hypotheses that suggest some degree of variation might improve the learning rate. Furthermore, such co...
