Regulatory decisions often must be made in an atmosphere of uncertainty, and arguments presented by the affected parties frequently
add to, rather than resolve, that uncertainty. Here, we examine several of the deregulatory decisions affecting the long-distance
market that were rendered by the FCC over the two-decade period following the divestiture of AT&T. Our purpose is to provide
empirical evidence relevant to some of the arguments regarding market conditions that were presented during that period. Findings
suggest that some of the more prominent allegations are not supported by the data.

The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances are to be applauded, the practitioner is left with a confusing array of rationales and the sense that almost any discount rate can be justified. This paper draws together these different strands and provides a critical review of past and present contributions to this literature. In addition to this we highlight some of the problems with employing DDRs in the decision-making process, the most pressing of which may be time inconsistency. We clarify their practical implications, and potential pitfalls, of the more credible rationales and argue that some approaches popular in environmental economics literature are ill-conceived. Finally, we illustrate the impact of different approaches by examining global warming and nuclear power investment. This includes an application and extension of Newell and Pizer [‘Discounting the benefits of climate change mitigation : how much do uncertain rates increase valuations?’ Journal of Environmental Economics and Management 46 (2003) 52] to UK interest rate data. 相似文献

Fiscal competition in space and time 总被引:1,自引:0,他引:1
David E. Wildasin 《Journal of public economics》2003,87(11):2571-2588
This paper analyzes fiscal competition among numerous spatially-separated jurisdictions in an explicitly dynamic framework. The degree of factor mobility between jurisdictions is imperfect because it is costly and time-consuming to adjust factor stocks. Even if it is harmful in the long run, taxation of mobile factors redistributes income in favor of the owners of immobile resources in the short run. The locally-optimal tax on mobile factors is lower, the faster the speed with which factors adjust to fiscal policy. Anticipated taxes are less beneficial than those that can be imposed unexpectedly. 相似文献

Motivated by problems of coordination failure in organizations, we examine how overcoming coordination failure and maintaining
coordination depend on the ability of individuals to observe others’ choices. Subjects’ payoffs depend on coordinating at
high effort levels in a weak-link game. Treatments vary along two dimensions. First, subjects either start with low financial
incentives for coordination, which typically leads to coordination failure, and then are switched to higher incentives or
start with high incentives, which usually yield effective coordination, and are switched to low incentives. Second, as the
key treatment variable, subjects either observe the effort levels chosen by all individuals in their experimental group (full
feedback) or observe only the minimum effort (limited feedback). We find three primary results: (1) When starting from coordination
failure the use of full feedback improves subjects’ ability to overcome coordination failure, (2) When starting with good
coordination the use of full feedback has no effect on subjects’ ability to avoid slipping into coordination failure, and
(3) History-dependence, defined as dependence of current effort levels on past incentives, is strengthened by the use of full
feedback.

This paper estimates the persistence of transient income shocks to farm households in rural Indonesia. Persistence is defined as the elasticity of a household's 1997 household per capita income with respect to its 1993 per capita income, controlling for time‐invariant characteristics of the household. Local rainfall levels are used as an exogenous source of transitory variation in 1993 income. Four main conclusions emerge. First, roughly 30% of household income shocks remain after four years. Second, the persistence of negative and positive shocks is approximately equal; if anything, positive shocks last longer. Third, neither positive nor negative income shocks disproportionately affect poor households. Finally, measurement error in income and unobserved household heterogeneity are important sources of bias. These findings cast doubt on common arguments advocating public intervention to stabilize or redistribute income, and suggest that anti‐poverty policy should address more permanent causes of household poverty. 相似文献

This paper is an exercise in the history of thought, which compares Austrian and neoclassical theories of the emergence of
private property rights, and examines, in part, the extent to which Austrians can be said to offer a commonly-agreed upon
explanation that parallels Carl Menger's exemplary story of the emergence of money. We address the sources of disagreement
(and apparent conflict) among emergence theorists in both schools. We try to show that some of the disagreement hinges on
an unclear meaning of the term “emergence,” which is resolvable, while other sources of disagreement are fundamental at the
methodological level.

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures
to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this
wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing
and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are
informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation
in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None
> All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on
information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected
utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result
contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed.
The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify
analytical welfare predictions of expected utility under different policy choices.

In this paper we study an industry in which there is an ongoing sequence of R&D races between two firms. Firms are engaged in product innovation. Products are horizontally and vertically differentiated. There are two key characteristics/dimensions to products, and the level at which these are embodied in products can be increased by R&D. At each time firms can spend R&D on improving their product in one or both dimensions. We allow the possibility of economies scope — so R&D undertaken in one dimension can spillover to the other. The question we are interested in is whether a firm that is ahead in a single dimension but behind in another will focus all its R&D effort in the area in which it is ahead (product specialisation), or whether it will try to do R&D in both dimensions in the hope that it might get ahead in both and end up with a superproduct that dominates in both characteristics. The outcome of this R&D competition determines a Markov transition probability matrix determining the evolution of the industry. We show that when the R&D technology is characterized by constant returns then the only steady-state outcome is one in which the economy stays forever in a position in which one firm produces a super-product and the other gives up doing R&D altogether. This outcome is unaffected by the degree of economies of scope. When the R&D technology is characterised by decreasing returns, then the industry will visit all states and so will exhibit both product specialisation and superproduct dominance at various times. Now the extent of economies of scope matters and we show that the greater the extent of economies of scope, the less likely is the industry to exhibit product dominance, and the more likely it is to exhibit product specialisation. 相似文献

Recently, two analyses have tried to put technological progress in a larger context. One interpretation hypothesizes that technological progress is likely to continue at increasingly higher rates of change. Another interpretation, which includes data from the beginning of the universe to the present, suggests that the universe is approaching a transition point in a logistic development of complexity. This logistic development is similar to the way ideas or products diffuse in a population, i.e., the rate of discovery in a field of knowledge is proportional to the amount discovered and the amount to be discovered. To test a part of this hypothesis, a leading indicator field (fundamental physics) was identified and the events in the history of this field were analyzed. Twelve subfields were identified and grouped into six stages. Each stage seemed to demonstrate a logistic-like development. By analyzing both the median time of development and the characteristic time of development of these stages, the overall development of this one field was found to suggest logistic development. These data seem to indicate that development in fundamental physics is slowing down, with at least one subfield beyond string physics yet to be developed. The data tend to support the hypothesis that a knowledge field can develop logistically. 相似文献

Leadership development and practice have traditionally been quite narrow, with a decided focus on the analytical realm of leadership. However, the contemporary climate of corporate scandal and resultant loss of societal confidence, coupled with the evolving demands, needs, and expectations of employees, point to the potential need for a more holistic approach to leadership. Thus, this article proposes how management education and leadership development programs can develop holistic leaders that are adept at operating in the analytical, conceptual, emotional, and spiritual domains of leadership practice. An integrated model for holistic leadership development and practice that addresses all four of these domains is proposed, and grounded in both established and emerging leadership development theory. Additionally, a leadership development classification scheme is proposed based on classroom, job, and organizational contexts. 相似文献
