Distributional Preferences and the Incidence of Costs and Benefits in Climate Change Policy

We explore the relationship between willingness to pay (WTP) for climate change mitigation and distributional preferences, by which we mean individuals’ opinions about who should be responsible for climate change prevention and whether the share of climate change impacts borne by the poor is a cause for concern. We use 1,770 responses to an online stated preference survey. The domestic costs in our survey’s policy choice scenarios are expressed as a set of randomized shares across four different payment vehicles, and the international cost shares are randomized across four groups of countries. We also elicit respondents’ perceptions of the likely regressivity of climate change impacts under a policy of business-as-usual. WTP is higher when larger cost shares are borne by parties deemed to bear a greater responsibility for mitigation, and when respondents believe (and care) that the impacts of climate change may be borne disproportionately by the world’s poor. That WTP for an environmental policy depends on the distributional consequences of the policy is an unsettling result: efficiency assessments are typically assumed to be separate from equity considerations in most benefit-cost analyses.     

The Challenges of Climate Policy

Climate policy planners and the public should be aware of both economic challenges and arguments that may influence the intensity of the climate policies with which they have to cope. This article examines six economic challenges: cap‐and‐trade versus taxes, non‐price regulations, energy efficiency policies, mitigation versus adaptation, trade effects, and transmission planning. Three additional challenges affect the end itself: ‘fat tails’, discount rates, and whether environmental protection should be evaluated by willingness to pay. If future generations cannot compensate the present for climate policy costs, climate policy is inherently redistributive and cannot be evaluated through cost–benefit analysis alone.     

Study on Medium- and Long-Term Fiscal Policies to Cope with Climate Change under the “Dual Carbon” Goals

Carbon peaking and carbon neutrality constitute an extensive, profound and systemic economic and social change. It is worthwhile to explore how fiscal policy, as a key institutional arrangement in the public policy system to cope with climate change, can play a fundamental and pillar role. Based on literatures, theories and empirical materials, this paper systematically explores the relationship between climate change and public finance. The fiscal impact of climate change will eventually be reflected in fiscal behavior, fiscal costs and fiscal relations, and the fiscal system has the adaptability of an “automatic stabilizer” and the proactiveness to enable the Discretionary Approaches function when facing climate change impacts. This implies such a governance logic of fiscal policy that is systematic, forward-looking and flexible in addressing climate change. In the future, it is necessary to further incorporate climate change or related environmental factors into the fiscal policy framework, target the two key aspects of mitigation and adaptation, and carry out a holistic, systematic and forward-looking reform of the existing fiscal expenditure policy, fiscal revenue policy, fiscal investment and financing policy, government budget system, government procurement policy and ecological compensation policy. While highlighting the “governance” function of fiscal policy in addressing climate change, Chinese government needs to strengthen the coordination and collaboration between fiscal policy tools and other public policies, and magnify the governance effectiveness of fiscal policy in the process of addressing climate change. This paper helps understand the positioning, role and influence of fiscal policy in the process of addressing climate change, provides a basis for better playing the fundamental and underpinning role of the modern fiscal system in the governance of ecological civilization, and presents an analytical framework for building a theoretical system of ecological fiscal governance.

A portfolio approach to climate investments: CAPM and endogenous risk

Is there a role for investments in climate change mitigation despite low expected return? We use a model of intertemporal expected utility maximisation to analyse this question. Similar to the capital asset pricing model (CAPM) the rate of return depends on the correlation of risk between the return on investments in climate change mitigation and the market portfolio, but in contrast to the classical CAPM we admit the fact that economic and environmental systems are jointly determined, implying that environmental risk is endogenous. Therefore, investments in climate change mitigation may reduce risk via self-protection and self-insurance. If risk reduction is accounted for in cost–benefit evaluations, climate investments may be justified despite low expected return. These aspects of climate investments are not, however, communicated via standard cost–benefit analyses of climate policy. Optimal climate policy may therefore be more ambitious than previously considered.     

Pro‐girl Bias in Intra‐household Allocation in the Rural Philippines: Revisiting the “Adult Goods” Approach

This paper detects pro‐girl (age 5–15) bias in intra‐household allocation of consumption budget in the rural Philippines using Deaton's “adult goods” method. Based on additional checks (including those for endogeneity), the results appear to be robust. The paper also finds that a larger share of girls among household members is positively associated with a larger budget share on transportation, suggesting that parents pay more for girls' transportation, possibly because of safety concerns. The results also suggest that, despite some earlier results in the literature, the adult goods method is capable of detecting gender bias, although alcohol and tobacco may not be suitable for detecting gender bias.     

Popular Support for Climate Change Mitigation: Evidence from a General Population Mail Survey

Using a sample of 1,651 US households, we explore some determinants of willingness to pay (WTP) for climate change mitigation programs. Our mail survey had a relatively low response rate, so we first use several additional data sources to build a detailed sample selection model. This model uses features of the survey instrument, measures of geographic vulnerability to climate change, seasonality, the political mix in the county, attributes of the address or addressee, and a set of factor scores from an extensive factor analysis of all census tracts in the US. We estimate this model jointly with a model to explain climate policy preferences as a function of the domestic and international distribution of policy costs as well as the climate change impacts that each respondent believes will occur under a policy of business-as-usual. Despite statistically significant patterns of nonresponse, selectivity effects are minimal in this case. WTP for climate change mitigation is greater when the domestic incidence of mitigation costs is borne mostly through higher energy taxes. It is also greater when costs are understood to be shared internationally with other groups of countries, rather than being borne mostly by a country group including the US. People are generally more willing to pay for climate change mitigation if they believe that the harm caused by climate change impacts will be substantial, rather than just moderate. The assistance of former UCLA undergraduate students Ivka Adam, Tashi Ghale, Michelle Gogolewski, Vilija Gulbinas, and Lindy Olsson was essential to survey development and administration.

THE LABOUR SUPPLY AND SAVINGS EFFECTS OF SUPERANNUATION TAX CHANGES*

This paper investigates the effects on labour supply, consumption and savings of a change in the superannuation tax structure, involving the taxation of contributions to a fund, pre‐retirement earnings of the fund, and the benefits received from the fund during retirement. The effects on lifetime plans of tax changes are investigated using a simple three‐period model in which the final period is retirement. The effects of unanticipated changes, requiring revisions to plans, are examined. Although the partial effects of particular tax changes are unambiguous, the effects of allowing for a government budget constraint mean that it is difficult to predict a priori how labour supply is likely to be affected. However, private savings unambiguously fall.     

ECONOMIC TRANSITION AND THE GENDER EARNINGS GAP IN CHINESE INDUSTRY: THE ROLE OF FIRM CHARACTERISTICS

This paper analyzes the gender wage gap in the post‐reform Chinese industry using a unique employer‐employee matched dataset. The analysis shows that the sex‐related wage premiums at the firm level account for almost all the portion of the gender wage gap that is not explained by observed personal characteristics. It is found that firms which have a larger pay gap between men and women are more likely to operate in the market with fierce competition, subject to a hard budget constraint, adopt piece rates, and have a lower degree of employees' influence.

MEDIA ADVERTISING AND BALLOT INITIATIVES: THE CASE OF ANIMAL WELFARE REGULATION

Spending on political advertising increases with every election cycle, not only for congressional or presidential candidates, but also for state‐level ballot initiatives. There is little research in marketing, however, on the effectiveness of political advertising at this level. In this study, we conduct an experimental analysis of advertisements used during the 2008 campaign to mandate new animal welfare standards in California (Proposition 2). Using subjects' willingness‐to‐pay for cage‐free eggs as a proxy for their likely voting behavior, we investigate whether advertising provides real information to likely voters, and thus sharpens their existing attitudes toward the issue, or whether advertising can indeed change preferences. We find that advertising in support of Proposition 2 was more effective in raising subjects' willingness‐to‐pay for cage‐free eggs than ads in opposition were in reducing it, but we also find that ads in support of the measure reduce the dispersion of preferences and thus polarize attitudes toward the initiative. More generally, political ads are found to contain considerably more “hype” than “real information” in the sense of Johnson and Myatt [Johnson, J. P., and D. P. Myatt. “On the Simple Economics of Advertising, Marketing and Product Design.” American Economic Review, 96, 2006, 756–84]. (JEL D12, D72, K32, L66, M37)     

Willingness to Pay for Ancillary Benefits of Climate Change Mitigation

Assessing the Willingness to Pay (WTP) of the general public for climate change mitigation programmes enables governments to understand how much taxpayers are willing to support the implementation of such programs. This paper contributes to the literature on the WTP for climate change mitigation programmes by investigating, in addition to global benefits, the ancillary benefits of climate change mitigation. It does so by considering local and personal benefits arising from climate change policies. The Contingent Valuation Method is used to elicit the WTP for ancillary and global benefits of climate mitigation policies in the Basque Country, Spain. Results show that WTP estimates are 53–73% higher when ancillary benefits are considered.     

Sustainable Development and a Dwindling Carbon Space

Curbing global warming by setting long term maxima for temperature rise or concentrations of greenhouse gases defines spaces within which further emissions of these gases are to remain (referred to here as ‘carbon spaces’). This paper addresses questions related to how to share between countries the carbon space and/or efforts to stay within it, in the perspective of sustainable development; different allocation mechanisms are reviewed, responding to criteria such as ‘responsibility’ for climate change, ‘capability’ to engage in abating it, and ‘potential’ or future contribution. The carbon space remaining at any time will depend on effective mitigation up till that time, and will condense if more stringent maxima are to be set; per capita this space becomes smaller with rising population. Sharing the carbon space in a fair way requires “convergence” of currently widely unequal per capita emissions. If the world is to stay within the carbon space consistent with <2° warming, then developed economies—the wealthiest sources of greenhouse gases should quickly and deeply engage in mitigation. Also, substantial mitigation is to take place in developing countries and that this will require substantial support to developing countries (financially, technologically). Changing development paths can make a major contribution to climate change mitigation; this requires changes in investment, production and consumption patterns. Green New Deals as proposed in the context of a widened response to the current economic crisis could become a first phase of a fundamental transition towards a decarbonised global economy worldwide. Concerns to do with equity as well as sustainability must be incorporated and integrated into coherent transitory strategies.     

International support of climate change policies in developing countries: Strategic, moral and fairness aspects

International transfers in climate policy channeled from the industrialized to the developing world either support the mitigation of climate change or the adaptation to global warming. From a purely allocative point of view, transfers supporting mitigation tend to be Pareto-improving whereas this is not very likely in the case of adaptation support. We illustrate this by regarding transfer schemes currently applied under the UN Framework Convention on Climate Change (UNFCCC) and the Kyoto framework.However, if we enrich the analysis by integrating distributional aspects, we find that international adaptation funding may help both the developing and developed world. Interestingly this is not due to altruistic incentives, but due to follow-up effects on international negotiations on climate change mitigation. We argue that the lack of fairness perceived by developing countries in the international climate policy arena can be reduced by the support of adaptation in these countries. As we show - taking into account different fairness concepts - this might raise the prospects of success in international negotiations on climate change. Yet, we find that the influence of transfers may induce different fairness effects on climate change mitigation negotiations to run counter.We discuss whether current transfer schemes under the UNFCCC and the Kyoto framework adequately serve the distributive and allocative objectives pursued in international climate policy.     

Population–Environment Interactions: European Migration, Population Composition and Climate Change

The paper addresses the collision of two twenty-first Century transitions—the unprecedented change in the size, composition, density and distribution of the human population, and rapid change in the earth’s natural environment, in part a response to the above. It argues that it is important to consider these aspects of population change and environment together in order to understand the reality of any mitigation that may be made. Following a review of research which is beginning to address not only the environmental impact of population growth, but also of changes in density, distribution and composition, the paper turns to explore the interaction of population composition and density with environmental change through addressing interactions between migration, ageing populations and climate change. It considers a key population question facing the EU, that of the demographic deficit, and addresses how the mitigating role of migration will be affected by future climate change. It thus considers whether migration is a valid policy approach in the context of Europe’s demographic deficit and the impact of climate change on this relationship.     

Identification of national priority areas for adaptation to climate change in China

The problem of global warming has been identified as the first in the list of the top ten environmental problems in the world. As climate change will seriously affect the social and natural world that people live in, so it may lay serious repercussions on economic progress, social improvement, and sustainable development. International bodies everywhere and many of the countries＇ governments are responding urgently to this call In recent years, climate change has affected different regions in China in different ways. In its national agenda, the Chinese government should address the problem of climate change and its negative impact on socio-economic development. In this endeavor the nation should introduce policies which will help its people and economy to adapt to these effects and changes. Priority-fields of adaptation to climate change are the sensitive areas or departments which are more vulnerable to the negative influences of climate change. The negative impacts of climate change in some parts of China are considered to be very serious indeed as they affect the whole economy and community. As a result, priority should be given to these more affected regions for the limited state financing. This paper defines adaptation and discusses the basic principles and programs in the identi.fication of national priority areas where adaptation should be exercised. Based on the past studies, four priority areas in China are identified, namely, disaster prevention and mitigation, water resources, agriculture, and ecosystem. An analysis on the identification procedures, and the reasons and tasks involved are given for each.     

Climate change impacts on irrigation water requirements: Effects of mitigation, 1990–2080

Potential changes in global and regional agricultural water demand for irrigation were investigated within a new socio-economic scenario, A2r, developed at the International Institute for Applied Systems Analysis (IIASA) with and without climate change, with and without mitigation of greenhouse gas emissions. Water deficits of crops were developed with the Food and Agriculture Organization (FAO)–IIASA Agro-ecological Zone model, based on daily water balances at 0.5° latitude × 0.5° longitude and then aggregated to regions and the globe. Future regional and global irrigation water requirements were computed as a function of both projected irrigated land and climate change and simulations were performed from 1990 to 2080. Future trends for extents of irrigated land, irrigation water use, and withdrawals were computed, with specific attention given to the implications of climate change mitigation. Renewable water-resource availability was estimated under current and future climate conditions. Results suggest that mitigation of climate change may have significant positive effects compared with unmitigated climate change. Specifically, mitigation reduced the impacts of climate change on agricultural water requirements by about 40%, or 125–160 billion m³ (Gm³) compared with unmitigated climate. Simple estimates of future changes in irrigation efficiency and water costs suggest that by 2080 mitigation may translate into annual cost reductions of about 10 billion US$.     

International climate regimes: Effects of delayed participation

This paper analyses how delayed participation by regions can affect international climate regimes in terms of the feasibility, costs, timing, magnitude and nature of the long-term mitigation response. We use the energy-systems optimization model MESSAGE to construct several climate change mitigation scenarios with various levels of regional participation in short-to-mid term. By comparing these with a global scenario that assumes full spatial and temporal flexibility throughout the century, we are able to evaluate how participatory decisions affect the mitigation response as well as the costs and technology choices. We find that short-term postponement of participation from some regions can often lead to a delay of mitigation measures on the global level. However, if the regional delay lasts until mid-century, participants of the regime are likely to increase their efforts in the short term. Mitigation costs are found to substantially increase as a result of delayed participation—the extent of the increase depends on the relative importance of the region that postpones its participation, the stringency of the climate target and the ability to reorganize mitigation measures. Our analysis also shows that a region's decision to delay its participation in an international climate regime can lead to accumulated inertia in its energy system and thus to a delayed ‘technological transition’ toward a low-carbon future.     

Diminishing Returns: Carbon Market Crisis and the Future of Market-Dependent Climate Change Finance

The current and future costs of meeting climate change mitigation needs in the global South vastly exceed levels of available funding from public sources in the North. As a possible solution to this problem, policy-makers and various observers have pushed increasingly for the adoption of market-based carbon financing strategies, with the United Nations Clean Development Mechanism (CDM) representing the most consistent application of this approach to date. Nevertheless, market-based carbon finance remains highly volatile given its heavy dependence on conditions in the broader global carbon market which remains in the throes of a devastating crisis, earning carbon the distinction of 2011s worst performing global commodity. By demonstrating that it is through carbon's market price that finance-generating investment in the CDM is largely derived, and which also determines the ex post value of CDM projects, this paper argues for the decoupling of climate change finance from carbon's market value. The need to do so is particularly pressing since, it is argued, the current crisis in the global carbon market reflects an embedded crisis tendency in that market, born in part from the political machinations through which it was born and which leaves it prone to persisting crises of oversupply.     

BANK COMPETITION AND FINANCIAL STABILITY: LIQUIDITY RISK PERSPECTIVE

We study whether competition affects banks' liquidity risk‐taking, which was at the heart of the 2008 financial crisis. We find that banks with greater market power take more liquidity risk, implying that decreased competition leads to financial fragility. During a financial crisis, however, the effect of market power on liquidity risk varies across bank size. Small banks with greater market power reduce liquidity risk while large banks with greater market power do not change their liquidity risk‐taking behavior. This suggests that enhanced charter values due to reduced competition lowers small banks' risk‐shifting incentives when their default risk significantly increases during a crisis.

The Socio-scientific Construction of Global Climate Crisis

This article adapts and applies a securitisation framework to produce an analytical explanation for the heightened geopolitical status of climate change over the past decade, as demonstrated by the breakthrough Paris Agreement of 2015. Rather than speech acts invoking security, the focus of this analysis is on the socio-scientific discourse of global climate crisis that emerged in the several year period leading to the 2009 COP 15 conference in Copenhagen. Two types of experts—contributory and interactional—are identified as the essential and interdependent actors that engaged in ‘crisification’, a novel crisis-based perspective on political agenda setting, in which climate crisis served as a primary discursive device employed by prominent advocates of urgent action. Contributory experts, that is, authoritative climate scientists and their institutions, together with interactional experts—non-scientist social actors who appropriated and mediated scientific data and knowledge in framing climate change as a global crisis—constituted an extended epistemic community of climate advocates. Through an array of speech acts, this extended community effectively co-constructed a convincing climate crisis discourse that consisted of quantitative data artefacts based on CO₂ concentration and global mean temperature, and qualitative invocations of existential threat to human civilisation, which contributed to the ascent of climate change on the global political agenda. In proposing crisification as a complement to securitisation, the article offers a theoretical innovation that facilitates constructivist analysis of issues framed as crises, including geopolitical problems in certain non-military sectors where crisis is a favoured label for perceived threats to core values.
