Kalai and Muller’s possibility theorem: a simplified integer programming version

We provide a respecification of an integer programming characterization of Arrovian social welfare functions introduced by Sethuraman et al. (Math Oper Res 28:309–326, 2003). By exploiting this respecification, we give a new and simpler proof of Theorem 2 in Kalai and Muller (J Econ Theory 16:457–469, 1977).     

The market premium for the option to close: evidence from Australian gold mining firms

This study shows the market value of gold mining firms contains a premium for the option to close. The sample uses 41 gold mining producers listed on the Australian Stock Exchange from 1987 to 2013. The premium of the market price over the present value of cash flows is isolated and a pooled cross‐sectional regression tests the degree of association between that premium and theoretical option premiums. The results show market prices incorporate a premium reflecting the option to temporarily close operations. The magnitude of the option premium to close depends on whether firms are out or in the money options.     

Testing the sufficiency of the theory of planned behavior: a case of customer dissatisfaction responses in restaurants

This study tested the sufficiency of both the Theory of Planned Behavior (TPB) and the extended TPB models by adding the variable of past behavior. In addition, the present study examined the mediating role of the TPB variables on the relationships between past behavior and customers’ intentions to engage in different types of dissatisfaction responses (i.e., voice, negative word-of-mouth communication, and exit). Results of the study demonstrated the strong predictive power of the original TPB mode but the inclusion of past behavior did not significantly improve the predictability of the three dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by TPB variables. In the contexts of negative word-of-mouth communication, the effect of past behavior on intention was mediated by attitude. Meanwhile, both subjective norm and perceived behavioral control mediated the relationship between past behavior and the intention to engage in voice behavior.     

New business models in online hotel distribution: emerging private sales versus leading IDS

This article deals with online hotel distribution. Its purpose is to investigate the private sales formula, which has recently emerged as a new business model. Two case studies are presented: Expedia, a leading internet distribution system (IDS), and Voyage Privé, a private sales Website. The study highlights the main features of the private sales formula by means of a cross-case comparison between the two travel Websites. The article ends with some final remarks on the main strengths and weaknesses of the formula as compared to the leading IDS in the online travel market.

Tax Policy and Human Capital Formation with Public Investment in Education

This paper studies the effects of distortionary taxes and public investment in an endogenous growth OLG model with knowledge transmission. Fiscal policy affects growth in two respects: first, work time reacts to variations of prospective tax rates and modifies knowledge formation; second, public spending enhances labour efficiency but also stimulates physical capital through increased savings. It is shown that Ramsey-optimal policies reduce savings due to high tax rates on young generations, and are not necessarily growth-improving with respect to a pure private system. Non-Ramsey policies that shift the burden on adults are always growth-improving due to crowding-in effects: the welfare of all generations is unambiguously higher with respect to a private system, and there generally exists a continuum of non-optimal tax rates under which long-run growth and welfare are higher than with the Ramsey-optimal policy.
