A note on the clarke and shrestha linear space model

This note re-examines two important propositions in the Clarke and Shrestha linear space model. We provide a complete analysis of designing and locating a secondary energy generation facility in the Clarke and Shrestha linear model and clarify two of their propositions.     

Tobin's q-Ratio and Market Reaction to Capital Investment Announcements

There is a significant positive relation between Tobin's q-ratio and the magnitude of stock market reaction to capital investment announcements. The findings have the following implications for capital investment theory: (i) The results provide evidence substantiating the link between the q-ratio and real investment for industrial firms. For public utilities however, no such link exists, (ii) The study finds that average q and marginal q are correlated but the relation is somewhat more complicated than simple equality as assumed by numerous empirical studies. (iii) The findings suggest that investors can use average Tobin's q-ratio to identify companies with profitable real capital investment opportunities.     

Quantifying uncertainty in applying importance-performance analysis

In a traditional importance-performance analysis (IPA), the information of uncertainty for importance and performance does not normally take into account from the survey but does commonly exist in practice. To further consider the uncertainty for each item from the survey results, the IPA under uncertainty method is proposed in this study. The traditional IPA possesses the ease of calculation and can be further viewed as a special case of the proposed IPA under uncertainty method, which is more complicated for computation but provides much more information for a decision maker to judge the strengths and weaknesses effectively by considering sampling, instrument effects, measurement conditions, sample effects, computational effects, random effects, etc. Finally, a brief case is illustrated to show how the proposed IPA under uncertainty method works and what the differences are between the traditional IPA and proposed methods.
