This article deals with the problem of item nonresponse in contingent valuation surveys using a payment-card method, by applying a grouped-data sample-selection estimation technique that is capable of imputing the missing values conditional upon a respondent's decision to answer a willingness-to-pay question. The advantage of the technique lies in its ability to utilize all of the information in the sample, permitting a more efficient estimation in the presence of item nonresponse bias. The major determinants of willingness to pay appear to be household income, number of children, education, perception of existing water quality, and identification with environmental issues.  相似文献

This paper examines the debate about whether early entrants/pioneers to an industry enjoy long–term advantage over their successors. While most of the research suggests that pioneers are advantaged, there are methodological problems with these studies that tend to enhance the likelihood that pioneers will be found to be more successful. Through a case study of the US animation industry, it is shown that being a late entrant was almost certainly advantageous to some of the companies concerned. The paper explores the reasons why some late entrants prevailed over others and some of the mechanisms that allowed late entrants to overcome pioneers. The factors involved in survival relative to pioneers include the limited protection of patents, complacency, the mobility of staff with expertise in a new technology (in this case cel animation), and the neglected importance of managerial and organizational factors. It is shown that the findings also have implications for the population ecology approach.  相似文献

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

Practice rights legislation in Canada continues to be contested 50 years after its first enactment. In Ontario, one of the earliest provinces to enact restrictive legislation, the challenges have focused on how the legislation has been implemented rather than on whether or not public accounting should be regulated. To better understand the contested issues in this field, we examine the process undertaken by the Public Accountants Council of Ontario to implement the Public Accountancy Act of 1950. Our analysis is based on the first 15 years of the minutes of the meetings of the Public Accountants Council for Ontario, augmented by other archival sources such as court cases, newspaper clippings, correspondence and reports. Our intent is to document the process and “logic of appropriateness” used by the Council to construct its identity and stake out its “regulatory space” in the face of the ambiguity of the law and pressure from interest groups. We also identify the contradictions that were institutionalized in this field resulting in repeated challenges to the Council. We conclude by relating the historical insights from this analysis to the continuing challenges to practice rights legislation in Ontario.  相似文献

Currently, entrepreneurs and corporations overwhelmingly do not view the alleviation of global poverty as a strategic priority. Yet business activity can have a negative as well as a positive effect on each distinctive form of poverty. In order to reduce poverty, entrepreneurs have to find ways of limiting the negative aspects. This might be achieved by deliberately augmenting strategies so that they can achieve a synthesis, in partnership with governments and NGO’s. Alan E. Singer is a reader in strategy at the university of Canterbury. He was the 2004/5 Aram chair of Business Ethics at Gonzaga. He is author of Strategy as Rationality (Avebury), Co editor (with Pat Werhane) of Business Ethics in Theory and Practice (Kluwer) and editor of Business Ethics and Strategy (Ashgate, forthcoming). He has written journal articles on many aspects of strategy and decision making and has served on the editorial boards of Journal of Business Ethics (to 2003), Human Systems Management, Journal of International Entrepreneurship, African Journal of Business Ethics and the Journal of Economic Development and Business Policy.  相似文献

This paper examines the competitive characteristics of U.S. manufacturers in the machine tool (MT) industry. After several decades of decline, this industry has recently shown signs of a modest but sustained recovery. Empirical evidence from a national survey of 104 MT producers suggests that the revival of this sector has been driven by a combination of factors, including renewed export involvement, improved customer support, and better product design. Although most MT companies are small-to-medium-sized enterprises (SMEs), the survey data show that very small SMEs are poorly represented in the recovery thrust of the industry as a whole. Our principal conclusion is that the MT industry has been following an export-led path toward stabilization, but that certain types of small producers are unlikely to thrive for very long. The most serious problems facing small producers include shrinking local markets, import competition, shortages of skilled labor, and cyclical demand.  相似文献
