Ups and Downs: Does the American Economy Still Promote Upward Mobility?
Examines trends in absolute intragenerational mobility by analyzing short- and long-term income fluctuations from 1967-2004, rates of recovery from declines, recovery time, and rates of gains compared with those of declines
Moving Forward with the Responsibility to Protect: Using Political Inertia to Protect Civilians
First formulated in 2005, the Responsibility to Protect has emerged onto the international legal landscape. This doctrine recently was expressed in the 2011 United Nations-authorized humanitarian intervention in Libya. Despite this promising start, the doctrine—designed to protect civilians from violence caused by their government or violence which the government is powerless to stop—has done nothing for the civilians in Syria. This Note explores the history of the Responsibility to Protect, identifies its flaws, analyzes proposed reforms, and ends with a suggested revision to the doctrine. This suggested revision would allow the political inertia of states to work for, rather than against, civilians
\u3cem\u3eProsecutor v. Taylor\u3c/em\u3e: The Implications for Bashar Al-Assad
Charles Taylor was the first sitting head of state to be indicted, tried, and convicted by an international criminal tribunal, the Special Court for Sierra Leone. This comment explores the procedural and structural similarities between the Special Court for Sierra Leone and the International Criminal Court. This comment then compares the evidence used to convict Charles Taylor and the evidence currently available about possible war crimes and crimes against humanity ongoing in Syria. Finally, this comment argues that Bashar al-Assad should be tried before the International Criminal Court, and that the Taylor case can be used as a template, due to the similarities between the courts and the evidence in each situation
MODELING ALTERNATIVE POLICIES FOR GHG MITIGATION FROM FORESTRY AND AGRICULTURE
A key consideration for development of energy and climate policy affecting the forestry and agricultural sectors is that the selection of specific mechanisms implemented to achieve bioenergy production and/or greenhouse gas (GHG) mitigation targets may have substantial effects on landowner incentives to adopt alternative practices. For instance, the prices of allowances and offsets are expected to diverge under some policies being considered where there is a binding cap on the quantity of offsets from the agricultural and forest sectors. In addition, provisions that limit or exclude specific practices from receiving carbon payments will affect the quantity and cost of GHG mitigation opportunities available. In this study, the recently updated Forest and Agriculture Sector Optimization Model with GHGs (FASOMGHG) was used to estimate GHG mitigation potential for private land in the contiguous U.S. under a variety of GHG price policies. Model scenarios suggest that U.S. forestry and agriculture could provide mitigation of 200 – 1000 megatons carbon dioxide equivalent per year (Mt CO2e/year) at carbon prices of 50/tCO2e. Binding limits on offsets have increasingly large effects on both the total magnitude and distribution of GHG mitigation across options over time. In addition, discounting or excluding payments for forest sinks can reduce annualized land-based mitigation potential 37-90 percent relative to the full eligibility scenario whereas discounting or excluding agricultural practices reduces mitigation potential by less than 10 percent.Climate policy, energy policy, FASOMGHG, GHG mitigation, Agricultural and Food Policy, Environmental Economics and Policy, Resource /Energy Economics and Policy, C61, Q42, Q54,
A Paradox Within The Time Value Of Money: A Critical Thinking Exercise For Finance Students
This study presents a paradox within the time value of money (TVM), namely, that the interest-principal sequence embedded in the payment stream of an amortized loan is exactly the opposite of the interest-principal sequence implicit in the present value of a matching annuity. We examine this inverse sequence, both mathematically and intuitively, and argue that it provides an excellent exercise for finance students to explore, both to enhance their critical thinking skills as well as to strengthen their understanding of TVM concepts. Additionally, such an exercise will involve them actively in the learning process, as mandated by AACSB International’s Eligibility Procedures and Standards for Business Accreditation
The marginal costs of different greenhouse gases: an application of FUND
The authors use FUND 3.9 to estimate the social cost of four greenhouse gases—carbon dioxide, methane, nitrous oxide, and sulphur hexafluoride—with sensitivity tests for carbon dioxide fertilization, terrestrial feedbacks, climate sensitivity, discounting, equity weighting, and socioeconomic and emissions assumptions. They also estimate the global damage potential for each gas—the ratio of the social cost of the non-carbon dioxide greenhouse gas to the social cost of carbon dioxide. For all gases, they find the social costs and damage potentials sensitive to alternative assumptions. The global damage potentials are compared to global warming potentials (GWPs), a key metric used to compare gases. The authors find that global damage potentials are higher than GWPs in nearly all sensitivities. This finding suggests that previous papers using GWPs may be underestimating the relative importance of reducing noncarbon dioxide greenhouse gas emissions from a climate damage perspective. Of particular interest is the sensitivity of results to carbon dioxide fertilization, which notably reduces the social cost of carbon dioxide, but only has a small effect on the other gases. As a result, the global damage potentials for methane and nitrous oxide are much higher with carbon dioxide fertilization included, and higher than many previous estimates
The coevolutionary biology of brood parasitism : a call for integration
Obligate brood-parasitic cheats have fascinated natural historians since ancient times. Passing on the costs of parental care to others occurs widely in birds, insects and fish, and often exerts selection pressure on hosts that in turn evolve defences. Brood parasites have therefore provided an illuminating system for researching coevolution. Nevertheless, much remains unknown about howecology and evolutionary history constrain or facilitate brood parasitism, or the mechanisms that shape or respond to selection. In this special issue, we bring together examples fromacross the animal kingdomto illustrate the diverseways in which recent research is addressing these gaps. This special issue also considers how research on brood parasitism may benefit from, and in turn inform, related fields such as social evolution and immunity. Here, we argue that progress in our understanding of coevolution would benefit from the increased integration of ideas across taxonomic boundaries and across Tinbergen's Four Questions: mechanism, ontogeny, function and phylogeny of brood parasitism. We also encourage renewed vigour in uncovering the natural history of the majority of the world's brood parasites that remain little-known. Indeed, it seems very likely that some of nature's brood parasites remain entirely unknown, because otherwise we are left with a puzzle: if parental care is so costly, why is brood parasitism not more common? This article is part of the theme issue 'The coevolutionary biology of brood parasitism: from mechanism to pattern'.Non peer reviewe
