Researching with whom? Stability and manipulation

This paper explores the existence of stable research teams, when the preferences of each agent depend on the set of researchers who are collaborating. We introduce a property over researchers’ preferences, called top responsiveness, guaranteeing the existence of stable research teams configurations. We also provide a stable mechanism, induced by the so-called top covering algorithm, which is strategy-proof when researchers preferences satisfy top responsiveness. Furthermore, we find that, in this framework, the top covering mechanism is the only strategy-proof mechanism that always selects stable allocations.     

A Cross‐national Comparison of R&D Expenditure Decisions: Tax Incentives and Financial Constraints*

We provide evidence on the impact of tax incentives and financial constraints on corporate R&D expenditure decisions. We contribute to extant research by comparing R&D expenditures in the United States and Canada, thereby exploiting the differences in the two countries' R&D tax credit mechanisms and generally accepted accounting principles. The two tax incentive mechanism designs are consistent with differing views of the degree of financial constraints faced by firms in these economies. Our sample also allows us to explore the effects of capitalizing R&D on Canadian firms. Employing a matched design, we document relations between tax credit incentives and R&D spending consistent with both Canadian and U.S. public companies responding as though they are not financially constrained. We estimate that the Canadian credit system induces, on average, $1.30 of additional R&D spending per dollar of taxes forgone while the U.S. system induces, on average, $2.96 of additional spending. We also find that firms that capitalize R&D costs in Canada spend, on average, 18 percent more on R&D. Collectively, this evidence is important to the ongoing debates in both countries concerning the appropriate design of incentives for R&D and is consistent with the assumptions found in the U.S. tax credit system, but not those found in the Canadian system.     

Definitions and progress of ecosystem health and ecological security

1. Introduction Development of human industrial civilization and predatory exploitation of natural resources have in- duced tremendous changes of ecological environment. In recent years, territorial and global environmental problems have increased, such as greenhouse effect, depletion of ozone, global warming, water scarcity, water pollution, acid rain, decrease of biodiversity, soil erosion desertification etc. These changes seriously intimidate the health and security of ecosystems, and dist…

The relative importance of journals used in operations management research A citation analysis

Journal rankings are important for a variety of reasons, most importantly as the basis of academic tenure and promotion decisions. A common approach in other fields is the citations methodology which is used in this study to determine the relative importance of various operations management (OM) journals. The citations analysis noted the frequency that all other journals are cited in Decision Sciences, Journal of Operations Management, and Management Science during the period 1992 to 1994. Rankings are provided based on total citations, citations per article, and citations per words published. The study shows that the journals with the most importance to OM research are Management Science, Decisions Sciences and Operations Research. Other journals important to OM research are the Harvard Business Review, Journal of Operations Management, and IIE Transactions.     

Review of tourism resources valuation

Tourism resources valuation is now a hot issue of the science of tourism resources, resources economics and environmental economics. This paper reviews research progresss on tourism resources valuation, introduces its theoretic basis, and elaborates two classical valuation methods： TCM and CVM. And two existing problems are discussed Firstly, tourism resources value constitution system is still under dispute. This paper puts forward the Value constitution system based on present value categories. Secondly, tourism resources valuation methods need further studies because both TCM and CVM have deficiencies. Finally, the paper points out the development direction of tourism resources valuation.

Technology assessment: Impact of high-tech engineering research on energy consumption

A technology assessment (TA) program was launched in Switzerland in 1991. One project in the series of pilot projects was meant to assess the impact of so-called LESIT technologies on energy consumption. (LESIT was a priority research program and a German acronym for power electronics, systems and information technology.) In this paper the institutional environment, applied methods and main results of the TA study are summarised. One of the questions that arose was whether it is reasonable to expect a high-tech engineering research program to serve any societal goals other than the more immediate technical and economic goals the research partners in university and industry are accustomed to follow. It was found that without special efforts this expectation was not realistic. Politically desirable goals are best served when enough emphasis, time, and money are given to the process of bringing together research partners from academia and industry who all have a (self-serving) interest in furthering the politically desirable goal and then support their collaboration.
