This paper presents tests of the theoretical validity of the contingent valuation (CV) method. The validity of CV is especially a concern when involving environmental goods with a predominant non-use value. One test of theoretical validity is the adding-up property that implies that a specific good should be equally valued irrespectively of it is being valued directly or built-up sequentially. In this CV study four independent sub-samples stated willingness to pay for the same composite good, or package, using different sequences. One sub-sample valued the composite good directly, while two sub-samples faced built-up sequences valuing first subsets of this composite good. A fourth sub-sample valued the composite good from a dividing-out approach, facing first the valuation of a larger multi-package. Theoretically expected sequencing effects were observed; the subset goods obtained higher values earlier in a sequence, and the dividing-out approach decreased the stated value for the composite good. Most importantly, these CV data did pass the tests of the adding-up property. 相似文献

Summary. For Bertrand duopoly with linear costs, we establish via a single (counter-)example that: (i) A new monotone transformation
of the firms' profit functions may lead to the supermodularity of transformed profits when the standard log and identity transformations
both fail to do so, and (ii) Topkis's notion of critical sufficient condition for monotonicity of a Bertrand firm's best-reply
correspondence cannot be extended to rely only on positive unit costs.

国际经济法是国际公法的一个重要组成部分,它经过了三个阶段的形成与发展。特别是自上世纪70年代以来,国际知识产权组织成立,国际知识产权的法律地位日益突出,知识产权的法律保护也就成为各国关注的焦点。如何推动更公平、平等的国际经济新秩序和知识产权法律的完善与发展,是值得研究的新课题。 相似文献

The largest market in national economies is the labor market. Labor market contracting is characterized by job search, often from unknown wage offer distributions. This paper reports experimental tests of finite horizon models of job search in which the wage offer distribution is unknown. Theoretically-optimal search from an unknown wage offer distribution can have the seemingly paradoxical property that some offers will be accepted that are lower than other offers that will be rejected in the same period of the search horizon. Thus the reservation wage property (or lowest acceptable wage path) may not exist. This can occur because an offer that is a priori relatively high (good news) can imply that it is highly probable that search is from a favorable distribution, and such an offer can look unattractive when it is an a posteriori relatively low offer from a favorable distribution (bad news). This paper reports results from experimental treatments for search from unknown distributions in which the reservation wage property does exist and treatments in which it does not exist. We find that the consistency of search behavior with search theory reported in earlier papers is robust to the presence or absence of the reservation wage property and to whether the draws come from known or unknown distributions. 相似文献

黔西南州是贵州省连片贫困的典型地区,是打赢脱贫攻坚战的关键区域。通过艰苦卓绝的奋斗,黔西南州的精准扶贫工作取得了重大成果。在“精神扶贫”领域,黔西南州在“扶智”“扶志”方面取得了很大成效,但还存在对“扶智”“扶志”认识不足、投入不足、主体错位,缺乏“扶智”“扶志”的文化自信等不足,这是持续打赢脱贫攻坚战面临的重大挑战。 相似文献

Do Institutions Cause Growth? 总被引:11,自引:5,他引:11
Edward L. Glaeser Rafael La Porta Florencio Lopez-de-Silanes Andrei Shleifer 《Journal of Economic Growth》2004,9(3):271-303
We revisit the debate over whether political institutions cause economic growth, or whether, alternatively, growth and human capital accumulation lead to institutional improvement. We find that most indicators of institutional quality used to establish the proposition that institutions cause growth are constructed to be conceptually unsuitable for that purpose. We also find that some of the instrumental variable techniques used in the literature are flawed. Basic OLS results, as well as a variety of additional evidence, suggest that (a) human capital is a more basic source of growth than are the institutions, (b) poor countries get out of poverty through good policies, often pursued by dictators, and (c) subsequently improve their political institutions. 相似文献
