This paper analyzes efficient government reactions to unanticipated tax avoidance. Quickly reforming tax laws to reduce the effectiveness of new tax avoidance techniques prevents widespread adoption, but indirectly encourages the rapid development of new avoidance methods if prior users are permitted to retain their tax benefits. Tax reforms that immediately prevent new avoidance mean that innovators need not fear imitation by competitors, and cannot rely on copying the innovations of others. Such an activist reform agenda diverts greater resources into tax avoidance activity, and might thereby lead to a faster rate of tax base erosion, than would a less reactive government strategy. Efficient government policy therefore entails either the retroactive elimination of tax savings, with possible associated costs, or else a deliberate pace of tax reform in response to taxpayer innovation. 相似文献

A three-generation planning model incorporating uncertain climate change is developed. Each generation features a production
activity based on capital and an exhaustible resource. An irreversible climate change may occur in period two or three, reducing
the productivity for this and the remaining generation. The model is solved by stochastic dynamic programming. If the climate
impact and climate change probability is constant, the optimal period one (and two) resource extraction is larger than for
the reference case of climate stability. If, however, climate impact and climate change probability increases with increased
aggregate resource use, this result is reversed. 相似文献

随着现代资本结构理论的发展,国内外企业都在学习如何在实务中对其加以灵活应用,使企业价值最大化.资本弱化就是这样一种应用,其目的在于企业通过资本结构安排,改变其纳税义务,起到避税的作用.目前,来自发达国家的外资企业在这一避税手法的使用上已达到了十分成熟的阶段,再加上我国现行税制框架尚未对资本弱化进行识别、规范和控制,造成了我国大量的税收利益流失.另外,在我国已逐渐认识到问题的紧迫性的情况下,如何进行监管和控制也是一个很大的技术难题. 相似文献

当前中国经济社会处于快速转型期,伴随着改革进程的不确定性风险日趋凸显,成为制约居民消费进一步扩张的重要因素。本文采用2003~2017年中国省级面板数据,考察了商业保险对居民消费行为的影响效应及其作用机制。研究发现,以商业保险密度和保险强度为表征的商业保险发展对居民消费有着显著正向影响,相较于农村居民消费,商业保险对城镇居民呈现更强的消费效应,同时财产保险消费效应明显高于人身保险对居民消费影响,进一步地,中介效应检验发现,不确定性缓解可能是商业保险影响居民消费的一个重要机制。基于此,本文认为,构筑完善的商业保险服务体系对于启动居民消费具有重要意义。 相似文献

Following a brief review of the main experimental work into the economics of risk and uncertainty, both static and dynamic, this paper reports the results of an experiment testing one of the key assumptions of the theory of dynamic economic behaviour—that people have a plan and implement it. Using a unique design which enables the plan (if one exists) to be revealed by the first move, the experiment was implemented via the Internet on a subset of the University of Tilburg's ongoing family expenditure survey panel. The advantages of using such a set of subjects for the experiment are twofold: the demographic characteristics of the set are known and therefore demographic inferences can be made; the representativeness of the set is known and therefore inferences about populations can be made. The results suggest that at least 36% of the subjects had behaviour inconsistent with the hypothesis under test: that people formulate plans and then implement them. Interestingly demographic variables are unable to explain the consistency or inconsistency of individuals. One conclusion is that subjects simply make errors. An alternative conclusion, consistent with previous experimental research, is that people are unable to predict their own future decisions. The implications for dynamic theory (particularly relating to savings and pensions decisions) are important. 相似文献

Uncertainty and Financing Constraints 总被引:5,自引:0,他引:5
Using a panel of Dutch listed firms this paper provides empirical evidence for the hypothesis that more risky firms are confronted with more severe capital market constraints than relatively less risky firms. The paper also contributes to the discussion on the usefulness of cash flow as a measure of financial constraints. We present a stochastic version of the Kaplan-Zingales (1997) model. We show that cash flow sensitivity can be used as a meaningful indicator of financing constraints if firms are classified by the degree of uncertainty they face and if the uncertainty originates from cost uncertainty. 相似文献

This paper investigates the influence of industry uncertainty on the decision by established firms to enter a new industry. Specifically, we examine the tension between the option to defer , which discourages entry in the presence of uncertainty, and the option to grow , which may encourage entry in the presence of uncertainty when there are early mover advantages. Empirical analysis on data from a broad array of industries revealed that the effect of uncertainty on entry is not monotonic. Our findings are the first to find support for the nonmonotonic effect of uncertainty that has only recently emerged in theoretical treatments of real options theory, and amplify the importance of considering both the option to defer and the option to grow when contemplating entry. Furthermore, we found evidence that the relationship between uncertainty and entry is moderated by: (a) irreversibility, which influences the value of the option to defer; (b) the total value of growth opportunities; and (c) early mover advantages, which magnify the value of growth options.
