Understanding environmental policy preferences: new evidence from Brazil

We examine the relationship between socio-economic factors and public opinion on environmental policies in Brazil, drawing on a survey conducted in June 2012. There are few systematic studies of the determinants of environmental preferences in emerging economies, and Brazil is a particularly interesting case because of its democratic political system, rapid economic growth, and importance for the global environment. In general, we find that the Brazilian public is highly supportive of environmental protection. To explain variation in environmental preferences, we focus on the effects of income and education. Many previous studies suggest that both should have positive effects, but the empirical evidence is mixed. Indeed, we find that income has no effect on environmental preferences. However, education is a strong predictor of environmental preferences. While college education is not necessary for environmental awareness, there is a large difference between Brazilians with primary and secondary education. For policy, the findings imply that investment in secondary education can raise environmental awareness, regardless of income levels

Information and energy policy preferences: a survey experiment on public opinion about electricity pricing reform in rural India

A common argument for the lack of economic reform in developing countries is popular opposition. If current economic policies are dysfunctional, could information about alternatives sway the voters? We examine if a simple argument emphasizing the need to increase electricity prices for improved supply can change public opinion in the case of India’s power sector reforms. The evidence comes from a survey experiment in rural Uttar Pradesh, which is both India’s largest state and has one of the lowest levels of household electrification. As expected, people respond to information about the relationship between electricity pricing, capacity investment, and reliability of supply by increasing their support for higher prices. However, no corresponding increase is observed for privatization of electricity generation. For external validity, we analyze an existing national survey on electricity privatization conducted in 2004/2005, finding patterns that support our argumen

Quantifying slum electrification in India and explaining local variation

Unreliable electricity supply is a major obstacle to economic development in countries such as India. While electricity problems in the rural areas are widely recognized, scholars have yet to analyze the situation in urban slums. Drawing on 2004–2005 survey data from the India Human Development Survey, we document the electricity situation in slums. We find that while households located in slums are less likely to have access to the electricity grid than other urban households, the situation is significantly better than in rural areas. Based on simulations, we find that a median household in a slum has 70% chance of having electricity. This number decreases to 50% for a household in a rural area and increases to 80% for households in urban areas. As to daily hours of electricity available for connected households, urban slums also fall between other urban and rural areas. Finally, we show that these conditions vary considerably by state. Slums located in states with low corruption and leftist governments have better electricity access on average than those in states suffering from corruption or that are ruled by rightist parties

The political economy of energy access: Survey evidence from India on state intervention and public opinion

In India, where energy access is limited, how does the public react to the government's inability to provide citizens with basic energy services, such as electricity and clean cooking fuel? We answer this question using a survey conducted in two rural villages of Uttar Pradesh. First, we examine the association between a respondent's opinion on state intervention and policy failure. Specifically, we focus on whether people who believe in state intervention are likely to have lower levels of satisfaction with the government's energy access policies. Second, we examine the link between policy failure and the likelihood that people consider a political candidate's energy views in voting. We find that people's preference for government intervention has a negative effect on satisfaction levels with government policies, and that people who blame the government for policy failures are less likely to take a political candidate's energy policies into account when voting

The European Union emissions trading system reduced CO2 emissions despite low prices

Significance International carbon markets are an appealing and increasingly popular tool to regulate carbon emissions. They put a price on carbon emissions and make pollution less attractive for regulated firms. However, carbon markets often produce prices which are deemed too low relative to the social cost of carbon. We argue that despite low prices, carbon markets can help reduce emissions. Using a statistical model and sectoral emissions data, we find that the EU ETS, which initially regulated roughly 50% of EU carbon emissions from mainly energy production and large industrial polluters, saved more than 1 billion tons of CO 2 between 2008 and 2016. This translates to reductions of 3.8% of total EU-wide emissions compared to a world without the EU ETS

Impact of Residential Substance Abuse Treatment on Affect and Personality-Related Variables Across Inner-city Substance Abusers

Substance abuse treatment outcome studies have shown positive effects for a large number of drug users with regard to reduction in substance use and criminal activity, as well as improvement of general well-being. However, high rates of relapse following treatment have compelled researchers to elucidate the individual difference factors that change among those who receive substance abuse treatment. Affect- (depressive and anxiety symptoms) and disinhibition-related variables (impulsivity, risk taking) may be of particular relevance. These factors are related to the development and maintenance of substance use and distinguish between substance users with and without Axis I and II disorders that may interfere with treatment success, such as depression, anxiety disorders, or antisocial personality disorder. Consequently, these factors may be considered important treatment targets. However, there currently is a dearth of research focused on understanding whether these variables are affected by standard substance use treatments, and more specifically, which variables may change throughout the course of substance use treatment. Given that many of these variables are considered to be enduring aspects of an individual's personality, the extent to which they are malleable by treatment is an important consideration. Moreover, to enhance the generalizability of these findings, it is important to understand the extent to which changes occur in more standard substance use treatments as opposed to more elaborate and targeted treatments that rarely are disseminated in real world treatment settings. Therefore, the purpose of the current study was to examine the effect of a residential substance use treatment program on particular affect- (e.g., depressive and anxiety symptoms, stress reactivity) and disinhibition-related variables (e.g., risk taking). A sample of 81 inner-city substance abusers were assessed on self-reported and behavioral measures of the above affect- and disinhibition-related variables that have previously found to be implicated in substance use over a 30-day course of treatment. A residential treatment program provides an optimal setting for evaluating changes as behavioral confounds (i.e., substance use) can be controlled, and the natural changes during abstinence can be measured with both reliability and validity. A significant pre-post treatment decrease was found on scores of risk taking, as indexed by the Balloon Analogue Risk Task (BART); levels of depressive symptomatology and stress reactivity also evidenced a significant pre-post decrease. These data are discussed with respect to implications for understanding the factors that underlie mechanisms of change during treatment, thereby informing substance abuse prevention and treatment programs

Economics of household technology adoption in developing countries: evidence from solar technology adoption in rural India

Innovation is one of the most important drivers of economic development. Even in developing countries, households have access to a wide array of new technologies. However, factors affecting households’ technology adoption decisions remain poorly understood. Using data on solar microgrid adoption from rural India, we investigate the determinants of household technology adoption. We offer all households identical solar products to avoid bias from product differentiation. Households pay a monthly fee for technology use, allowing us to abstract away from credit constraints as a barrier to adoption. The results show that household expenditures and savings as well as the household head’s entrepreneurial attitude are strong predictors of adoption. In contrast, past fuel expenditures, risk acceptance, and community trust are not associated with technology adoption decisions. These findings suggest new directions for research on the microeconomics of household technology adoption, which is critical for sustainable development among the poor in developing countries

Does basic energy access generate socioeconomic benefits? A field experiment with off-grid solar power in India

This article assesses the socioeconomic effects of solar microgrids. The lack of access to electricity is a major obstacle to the socioeconomic development of more than a billion people. Off-grid solar technologies hold potential as an affordable and clean solution to satisfy basic electricity needs. We conducted a randomized field experiment in India to estimate the causal effect of off-grid solar power on electricity access and broader socioeconomic development of 1281 rural households. Within a year, electrification rates in the treatment group increased by 29 to 36 percentage points. Daily hours of access to electricity increased only by 0.99 to 1.42 hours, and the confidence intervals are wide. Kerosene expenditure on the black market decreased by 47 to 49 rupees per month. Despite these strong electrification and expenditure effects, we found no systematic evidence for changes in savings, spending, business creation, time spent working or studying, or other broader indicators of socioeconomic development

Does politics impact carbon emissions?

"Do political variables influence long-term environmental transitions? The discussion on the determinants of the environmental performance of countries has been dominated by a focus on the Environmental Kuznets curve. This concept concentrated primarily on the role of economic factors, in particular per capita income levels. By contrast, we outline both conceptually and empirically how political factors can affect long-term carbon trajectories. Our findings from an error-correction model suggest that political factors are an important explanatory variable for carbon emissions in over 100 countries during the period 1970-2004. The results show that political capacity reduces carbon emission in OECD countries whereas political constraints, democracy and the Kyoto Protocol reduce long-term carbon emission in the group of all countries as well as in non-OECD countries."

Policy coordination and energy efficiency

Is the organisation of ministerial portfolios associated with governments' policy output? Political agendas and preferences alone cannot fully explain policy choices; the organisational design is also critical (Hall 1996). Governments cannot formulate coordinated strategies unless they facilitate such coordination through the organisation and design of ministerial portfolios. This 'political/policy game' should have direct effects in policy continuity and effectiveness. We investigate this problem in the context of energy efficiency policy. Do policies targeting energy efficiency in residential buildings vary depending on where the portfolios of Energy and Environment sit? Poorly insulated houses contribute significantly to countries' CO2 footprint and lead to higher levels of energy poverty in industrialized countries. Effective solutions exist in theory but often remain evasive in practice, at least in part because governments’ policy strategies are often uncoordinated. Using unique new data on the structure of ministerial portfolios in fifteen European countries over thirty years, we test the hypothesis that when the departments of Energy and the Environment are major portfolios and have been in place for longer period of time (spanning government changes), they will be associated with a higher number of policy initiatives aiming at higher levels of energy efficiency. In contrast, when the department of Energy is a minor portfolio under Business or Economics, policies for improving energy efficiency are likely to be fewer and less ambitious
