The general equilibrium effects of high-occupancy vehicle lanes on congestion,sprawl, energy use,and carbon emissions

High-occupancy vehicle (HOV) lanes have been promoted to encourage carpools, reduce traffic congestion, and improve air quality. At the partial equilibrium level, commuting with three workers per automobile clearly reduces highway congestion, lowers carbon emissions, and saves energy compared with three single drivers. This paper develops a numerical urban simulation model to generate the general equilibrium effects of HOV lanes on urban spatial structure, energy use, and greenhouse gas emissions. The major findings are that while HOV lanes reduce traffic congestion and improve welfare, the fall in transportation cost leads to urban sprawl, which results in higher dwelling energy use and a larger carbon footprint. Overall, the HOV lane policy has little effect on total energy consumption and carbon emissions. This is another classic case of general equilibrium effects reversing the partial equilibrium effects of an urban policy. In contrast, a gasoline tax policy leads to less urban sprawl but is less effective at lowering energy consumption and carbon emissions. Imposing congestion tolls is a more effective tool at reducing traffic congestion, saving energy, and lowering carbon emissions.     

Afghanistan and the Opium World Market: Poppy Production and Trade

The Afghan poppy cultivation is presented here as a case in point to exemplify the linkages between external influences and local effects. World market and power relations have influenced cultivation patterns, processing, and trafficking. At the same time, poppy cultivation pinpoints an internal development which is strongly linked to deteriorating state control, warlordism, and regional power politics. Opium production has served as a major source of revenue for the upholding of disparate political structures which reflect the present political map of Afghanistan. Poppy cultivation in Afghanistan gained a substantial push during the last quarter century, from an annual production of 200 tons in 1979 to 4,200 tons in 2004, making use of former development efforts in creating irrigated oases in Helmand and Nangarhar. Prices rose after the Taliban's 2001 ban on production, raising farmers' incomes substantially and turning opium into an unrivalled cash crop. Fairly new production zones have been added in recent times; for example, Badakhshan—the stronghold of the Northern Alliance—has gained the third position with major increases in the last few years. Afghanistan's poppy cultivation and opium production has to be interpreted in terms of globalization and fragmentation. Drug trafficking affects the neighboring states, namely, Iran, Tajikistan, and Pakistan, as they function as consumer markets as well as trade routes for contraband drugs heading towards the West. Consequently, the Afghan poppy cultivation is interpreted in a holistic manner.     

INTERACTION BETWEEN THE COAL-ENERGY-CHEMICALS AND IRON-STEEL CYCLES IN THE DONETS BASIN

An economic-geographic model of two technologically related industry groups in the Donets Basin (coal-energy-chemicals and iron-steel) reveals bottlenecks that reduce the cost-effectiveness of industrial performance. They include cross hauls of coal, amounting to about 5 million tons a year within the Donets Basin; in-shipments of up to 3 million tons of coal from outside the Donbas, and the waste of 3 billion m³ of blast-furnace gas. Remedies that would insure more rational utilization of fuel and energy resources are proposed.     

Can Affirmative Motivations Improve Compliance in Emissions Trading Programs?

Early emissions trading programs have obtained a very high rate of compliance, in part by using continuous emissions monitors (CEMs) that automatically record emissions data on a 24‐hour basis. As they expand into a wider range of pollutants and sources, however, such policies will have to rely on less automated forms of self‐reporting. This article asks if improved “affirmative motivations” for compliance based on perceptions of a policy's fairness could reduce the likelihood of underreporting, thereby lowering verification costs without unduly jeopardizing environmental integrity. Using a computerized laboratory emissions trading market, we find that many subjects reported emissions honestly in situations where dishonest reporting would have been more profitable, as well as a statistically significant association of affirmative motivations based on perceptions of a policy's fairness with honest reporting. These results suggest that designing an emissions trading program to increase its perceived fairness among users has the potential to increase honest emissions reporting and reduce monitoring costs.     

THE SPATIOTEMPORAL EVOLUTION OF U.S. CARBON DIOXIDE EMISSIONS: STYLIZED FACTS AND IMPLICATIONS FOR CLIMATE POLICY

We characterize the evolution of U.S. carbon dioxide (CO₂) emissions using an index number decomposition technique which partitions the 1963–2008 growth of states’ energy‐related CO₂ into changes in five driving factors: the emission intensity of energy use, the energy intensity of economic activity, the composition of states’ output, per capita income and population. Compositional change and declining energy intensity attenuate emissions growth, but their impacts are offset by increasing population and income. Despite absolute interstate divergence in both emissions and their precursors, states’ emission‐ and energy intensities—and ultimately, CO₂—appear to be stochastically converging. We assess the implications of these trends using a novel vector autoregression (VAR) emission forecasting technique based on our index numbers. The resulting emission projections are comparable to, but generally exceed, those forecast by the 2010 EIA Annual Energy Outlook.     

Labour Productivity and Energy Use in a Three‐Sector Model: An Application to Egypt

This article presents a model of a developing economy with three sectors — industry, agriculture and energy. Industry and energy are assumed to be demand‐constrained, but agriculture supply‐constrained. The model highlights: (a) structural transformation, through labour transfer from agriculture to industry; (b) inflation, driven by the interaction of demand and the supply constraint in agriculture; and (c) the link between energy use and labour productivity. Employing a Kaldor‐Verdoorn productivity rule in industry augmented with energy intensity — energy per unit of labour — as an argument, we emphasize that labour productivity growth is driven by energy intensity rather than energy productivity growth. As a consequence, emissions reduction without North–South technology transfer and financial assistance costs growth.     

Infrastructural Activism: Google Bus Blockades,Affective Politics,and Environmental Gentrification in San Francisco

Between 2013 and 2018, the San Francisco Bay Area saw the rise of “Google bus blockades”—a form of protest against gentrification, growing inequality and a housing crisis linked to the economic impacts of the technology sector on the region. Based on two years of ethnographic fieldwork with housing activists in the San Francisco Bay Area, this article argues that the disruptive tactic of “the Google Bus blockade” can be understood as a form of infrastructural activism—a flexible political form that uses the interruption of infrastructure for political ends. The blockades politicised the “Google buses” and transformed them into symbols of gentrification and sites of resistance. Protestors constructed a political analysis that drew connections between struggles for housing, racial and environmental justice and brought together material, affective and political critiques of infrastructure.     

Afghanistan: ‘spoilers’ in the regional security context

The ongoing international military withdrawal from Afghanistan has set the stage for energising the activities of Afghanistan's external stakeholders to re-evaluate their activities. The possible return of the Taliban in some form could compel Afghanistan's current external partners—Iran, India and Russia—to turn into limited spoilers. The absence of an international guarantor in Afghanistan from December 2014 is likely to encourage Pakistan—a greedy spoiler—to intensify its meddling as a means to reposition the Taliban—a total spoiler—at the helm of Afghan affairs. The combination of limited, greedy and total spoilers threatens to undermine security and state-building processes.     

A new process for negotiating multilateral environmental agreements? The Asia–Pacific climate partnership beyond Kyoto

The Kyoto Protocol is widely regarded as representing a failed approach to the problem of climate change, especially since the US and Australia have declined to ratify, and developing countries such as India and China—sources of much future emissions growth—have signalled an unwillingness to take on obligations for binding reductions within the framework of an extended Kyoto-like instrument. A new Asia–Pacific Partnership to deal with the problems has emerged and held its first meeting in Sydney in January 2006. Involving Australia, China, India, Japan, Korea and the US, this new partnership provides not only an approach better suited to the interests and resource endowments of the region, but a new model for negotiating multilateral environmental agreements (MEAs). In the past, MEAs have been beset by a dilemma, in that the slow pace of their negotiation was overcome by devices (such as lowest common denominator measures, creative ambiguity, iterative functionalism, and double standards provisions) that limited their effectiveness. This article argues that by involving only six parties which account for half of existing emissions, the new Partnership provides the opportunity for better policy to be developed among a smaller number of parties, with the potential to overcome the pitfalls of past MEAs.     

Green cities? Urbanization,trade, and the environment

Is urbanization good for the environment? This paper establishes a simple core–periphery model with monocentric cities, which comprises key forces that shape the structure and interrelation of cities to study the impact of the urban evolution on the environment. We focus on global warming and the potential of unfettered market forces to economize on emissions. The model parameters are chosen to match the dichotomy between average “large” and “small” cities in the urban geography of the United States, and the sectoral greenhouse gas emissions recorded for the United States. Based on numerical analyzes we find that a forced switch to a system with equally sized cities reduces total emissions. Second, any city driver which pronounces the asymmetry between the core and the periphery drives up emissions in the total city system, too, and the endogenous adjustment of the urban system accounts for the bulk of the change in emissions. Third, none of the city drivers gives rise to an urban environmental Kuznets curve according to our numerical simulations. Finally, the welfare‐maximizing allocation tends to involve dispersion of cities and the more so the higher is the marginal damage from pollution.     

Substitute or addition to hypermobile lifestyles? Second home mobility and Finnish CO2 emissions

Tourism produces an increasing share in global greenhouse gas (GHG) emissions. These are mostly derived from transport emissions, and long-haul air travel in particular. Short-haul domestic tourism is believed by some to be a potential substitute for long-haul tourism. Using the example of Finland this paper examines the extent to which domestic second home tourism can substitute for other leisure trips and therefore contribute to reductions of travel-generated GHG emissions. Survey data are used to evaluate the CO₂ emissions caused by travel to domestic second homes, and to create statistical models that verify if the owners of domestic second homes travel to other leisure destinations less frequently than others, and if they cause less emissions by their leisure mobility than others with comparable economic and demographic background. We find that although the owners and users of domestic second homes travel for other leisure purposes less frequently than others, this does not mean their leisure mobility generates less emissions. Overall, owners of second homes produce significantly more CO₂ by their leisure mobility than non-owners. The use of second homes does not seem to be a substitute for high emission long-haul travels, but rather a part of an overall highly mobile leisure lifestyle. It is therefore necessary to better understand and influence the entire range of individual mobility behaviours in order to reduce travel-related GHG emissions.     

Early copper smelting at Itziparátzico,Mexico

Archaeological fieldwork and archaeometallurgical analysis have identified a Late Postclassic regional centre of copper production in western Mexico. The total output from a single unit of production at the site of Itziparátzico is an estimated ten tons of copper and nearly forty tons of slag over the lifetime of the installation. It is argued that this smelting was based on slag-tapping furnaces, a technology previously unknown from Mesoamerican archaeological sites. The smelting site is in dense woodland with ample fuel supply, some 125 km from the next mining area with documented contemporary ore extraction; the copper produced would have been passed on to the capital, another 60 km away, for further distribution and working. The scale of production at Itziparátzico indicates that copper smelting was done by part-time specialists embedded in a predominantly agricultural economy, and formed part of a centrally organized network of mining, smelting and processing of copper to supply the Tarascan state.     

Ecological Modernisation and the Governance of Carbon: A Critical Analysis

Abstract: In this paper, we use insights derived from a critical evaluation of ecological modernisation theories to examine the origins and influence of new, market‐based, forms of carbon governance. Focusing on two key examples—emissions trading in Europe and the global market in offsets—we argue that ecological modernisation theories can help us understand the processes through which the seemingly intractable problem of climate change has been reframed as an opportunity to construct a new carbon economy and anticipate some of the tensions, contradictions and limits of such an approach. We then explore the governance dimensions of these novel market mechanisms, look at how they work, and then discuss whether, to what extent and for whom they work. We highlight a series of (un)‐intended consequences that flow from these practices and modes of governing. We conclude by discussing the significance of these observations both for debates on climate change and the governance of carbon and for theories of ecological modernisation.     

REGULATORY FEDERALISM AND THE DISTRIBUTION OF AIR POLLUTANT EMISSIONS*

ABSTRACT Recent empirical work suggests that (i) incomes are converging through time, and (ii) income and pollution levels are linked. This paper weds these two literatures by examining the spatial and temporal distribution of pollution. After establishing that theoretical predictions about whether pollution will converge are critically linked to certain structural parameters, we explore pollution convergence using state‐level data on two important pollutants—nitrogen oxides and sulfur oxides—from 1929 to 1999. We find stronger evidence of converging emission rates during the federal pollution control years (1970–1999) than during the local control years (1929–1969). These results suggest that income convergence alone may not be sufficient to induce convergence of pollutant emissions.     

The Effect of NAFTA on Energy and Environmental Efficiency in Mexico

Prior to Mexico's entry to the North American Free Trade Agreement (NAFTA), predictions of the consequent impact on the environment in that country ranged from the dire to very optimistic. This article investigates NAFTA's outcomes in terms of energy use and the emission of atmospheric pollutants. Specifically, has entry into NAFTA led to a convergence or divergence in indicators of emissions, environmental efficiency, and emissions‐specific technology in Mexico, the United States, and Canada? A battery of tests is applied to these indicators for energy use and carbon, sulfur, and NOx emissions in the three countries. The results show that the extreme predictions of the outcomes of NAFTA have not materialized. Rather, trends that were already present before the introduction of NAFTA continue and, in some cases, improve post‐NAFTA, but not yet in a dramatic way. There is strong evidence of convergence across the three countries toward a lower intensity of energy use and emissions per unit of GDP. Although intensity is rising initially for some variables in Mexico, it eventually begins to fall post‐NAFTA. Per capita emissions of sulfur and NOx also show convergence, but this is not the case for energy and carbon, and the latter variables also drift moderately upwards. The state of technology in energy efficiency and sulfur abatement is improving in all countries, although there is little, if any, sign of convergence and NAFTA has no effect on the rate of technology diffusion. However, total energy use and carbon emissions increase both pre‐ and post‐NAFTA and total NOx emissions increase in Mexico. Only total sulfur emissions are stable and falling in all three NAFTA partners.     

Sword,Priest and Conversion: On Religion and Apostasy in South Slav Literature in the Period of National Revival

Abstract

This article examines the works of four writers of Croatian, Slovene, Serbian and Bosniak literature in the period of National Revival, in their literary, historical and discursive contexts: Pre?ern’s Krst pri Savici, Ma?urani?’s Smrt Smail-age ?engi?a, Njego?’s Gorski vijenac and Ba?agi?’s Abdullah Pa?a. Three of the four authors were also statesmen, and all four are considered canonical national writers. There is a striking similarity between their otherwise different works, resulting from speeches by priests who either demand and justify conversion, or vehemently oppose it and call for vengeance. In all four works, the enemy is not a foreign conqueror, but an apostate who sides with the conqueror by accepting his faith. Although in all four works the values of the epic and heroic world are pronounced dead, epic action — a ’sword’ — is still very much alive. Though the central act of conversion is accompanied by religious symbolism which gives rise to the impression of a clash of religions, in all four works conversion does not have a religious meaning, it is purely political.     

Childhood,mental capacity and conversion to Islam in the Ottoman state

Abstract

In this paper I explore the conversions of minors as they were presented in the registrations of the ?eriat court (sicil). Two types of records shed light on the conversion process: the summaries of lawsuits and the sporadic registrations of converts' names. As the mental capacity of a child was regarded as of crucial importance when considering the child's conversion, the kadi classified the children into three different age-groups. Special attention was given to children of seven to ten years: their conversion was approved after an examination of their mental capacity. We can assume that these cases concealed some forms of pressure as well. The conversion of adolescents should be regarded as part of a wider phenomenon — the conversion of rural migrants to Salonica.
