In any given year, the Federal Communications Commission confronts many issues of interest to economists. This paper summarizes four issues of interest during the last year: Spectrum Auctions, Media Ownership, Quality-Adjusted Cable Prices, and Leased Access. It highlights the role that economic analysis played in each and identifies areas where further research would be fruitful. This article was drafted while the first author was Chief Economist at the Federal Communications Commission. The opinions expressed here are solely those of the authors and do not necessarily reflect those of the Federal Communications Commission, its Commissioners, or its staff. We would like to thank Larry White and Tracy Waldon for helpful comments.  相似文献

Although many of today's ecological, climatic and socio-economic problems seem unprecedented, similar events have occurred in the past. As such, historic periods of climatic and economic volatility can be used as a way of developing frameworks for analyzing today's predicament. Western Europe's “middle ages” (circa 11-14th century) may be one such case. By the 12th century, medieval Europe had shifted from the subsistence agrarian economy that emerged following the collapse of the Roman Empire to one where spatially dispersed trade in agricultural commodities helped support a complex society that devoted considerable resources to cultural works. This shift was facilitated by new institutional arrangements centred on monastic orders that provided access to both new agricultural and food processing technologies as well as trade routes. These institutional arrangements contributed to population growth and land clearing. All of these factors increased the wealth of society but also concentrated this wealth in a small number of communities that were dependent on an ever-increasing and exploited hinterland for resources. Ultimately, this created a tightly coupled continent-wide subsistence system that was vulnerable to the weather, economic and disease shocks of the 14th century when Europe's population declined by perhaps 50%. In exploring this history, the goal of this paper is to draw on a diverse theoretical body of literature (that includes resiliency theory, landscape ecology, political science and ecological economics) to develop a series of hypotheses about how large-scale complex civilizations can become vulnerable to climate change.  相似文献

For those striving to create good companies it would at least be helpful to be able to identify them. While the very best companies usually perform well under any measure of corporate success, most conventional measures stack the odds in favour of certain companies over others. Capital intensity and gearing frequently interfere in the appropriate ranking of firms. This paper analyses some of the problems of commonly quoted performance indicators, and nominates an alternative.  相似文献

Efforts to restore the Lower Mississippi Alluvial Valley's forests have not achieved desired levels of ecosystem services production. We examined how the variability of returns and the flexibility to change or postpone decisions (option value) affects the economic potential of forestry and agroforestry systems to keep private land in production while still providing ecosystem services. A real options analysis examined the impact of flexibility in decision making under agriculture, forestry, and agroforestry and demonstrated that adoption of forestry or agroforestry systems is less feasible than would be predicted by deterministic capital budgeting models.  相似文献

Academics rank high among those groups of people who derive their sense of personal identity and meaning from their particular form of employment. Yet, part of what being a university academic means – and part of the satisfaction that academics obtain from their jobs – lies in being paid to engage in ‘absorbing play.’ This essay explores some ways in which concepts of work and play, labour and leisure, are at issue in the organisation, imagination and experience of professorial employment in general, and how, in particular, such concepts informed and were negotiated in the interdisciplinary space of the 2006‐7 Humanities Institute seminar at the University of Texas at Austin out of which the papers collected in this special issue emerged.  相似文献

This paper examines the impact of coordination costs and organizational rigidity on the returns to diversification. The central thesis is that coordination costs offset economies of scope, while organizational rigidity increases coordination costs, further constraining economies of scope. The empirical tests of this proposition identify the effects of coordination and organizational rigidity costs on business unit and firm productivity, using novel data from the Economic Census on taxicab and limousine firms. The key results show that coordination and organizational rigidity costs are economically and statistically significant, while organizational rigidity itself accounts for a 16 percent decrease in paid ride‐miles per taxicab in incumbent diversifiers, controlling for the other costs and benefits of diversification and incumbency. The findings suggest that coordination costs, in general, and organizational rigidity costs, in particular, limit the scope of the firm. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

We evaluate data on choices made from convex time budgets (CTB) in Andreoni and Sprenger (Am Econ Rev 102(7):3333–3356, 2012a) and Augenblick et al. (Q J Econ 130(3):1067–1115, 2015), two influential studies that proposed and applied this experimental technique. We use the weak axiom of revealed preference (WARP) to test for external consistency relative to pairwise choice, and demand, wealth and impatience monotonicity to test for internal consistency. We find that choices made by subjects in the original Andreoni and Sprenger (Am Econ Rev 102(7):3333–3356, 2012a) paper violate WARP frequently; violations of all three internal measures of monotonicity are concentrated in subjects who take advantage of the novel feature of CTB by making interior choices. Wealth monotonicity violations are more prevalent and pronounced than either demand or impatience monotonicity violations. We substantiate the importance of our desiderata of choice consistency in examining effort allocation choices made in Augenblick et al. (Q J Econ 130(3):1067–1115, 2015), where we find considerably more demand monotonicity violations, as well as many classical monotonicity violations which are associated with time inconsistent behavior. We believe that the frequency and magnitude of WARP and monotonicity violations found in the two studies pose important confounds for interpreting and structurally estimating choice patterns elicited through CTB. We encourage researchers employing CTB in present and future experiments to include consistency tests in their design and pre-estimation analysis.  相似文献

Based on research on meta-stereotypes and signaling theory, we examined the effects of organizational signaling on the attraction of autistic applicants. Our model predicted that meta-stereotypes and the combination of expressed and evidence-based autism-conscious signals would have simple and joint effects on candidates' fit perceptions, which would, in turn, affect their job pursuit intentions. Further, we expected that the effect of signaling on our outcomes would be weaker among candidates with strong negative autism meta-stereotypes. Prior to testing our hypotheses, we conducted a focus group to determine the supports that autistic job seekers deemed most important. As the ability to work from home (WFH) was overwhelmingly the most cited support, we included this as our evidence-based signal. Specifically, we examined the combined effect of disability-conscious (vs. disability-blind) diversity statements and WFH (vs. retirement benefits) on expected fit and subsequent job pursuit intentions. Both meta-stereotypes and combined signals significantly influenced fit expectations. Further, the autism-friendly signals significantly affected the fit of candidates with weak and moderate negative meta-stereotype, but not the fit of candidates with strong meta-stereotypes. In addition, our results indicate that the signal x meta-stereotype interaction had an indirect effect on job pursuit intentions. Findings are discussed vis-à-vis the research on signaling theory and practical guidance is offered to employers seeking to attract the growing number of autistic job seekers.  相似文献

In consequence of world population growth, technological dependence and natural resource depletion, mankind, especially in the developed world, which operates with a free-trade tradition, faces unprecedented challenges to civilised survival. Following the Harrison Brown precedent in assessing the dynamics of social systems' responses to survival pressures, the authors have selected themes of theoretical social science and juxtaposed them for insights into the nature of and paths to our collective future, here characterised in three alternative scenarios.  相似文献
