Cheaper,Greener and More Efficient: Rationalising UK Carbon Prices

Current UK energy use policies, which primarily aim to reduce carbon emissions, provide abatement incentives that vary by user and fuel, creating inefficiency. Distributional concerns are often given as a justification for the lower carbon price faced by households, but there is little rationale for carbon prices associated with the use of gas to be lower than those for electricity. We consider reforms that raise carbon prices faced by households and reduce the variation in carbon prices across gas and electricity use, improving the efficiency of emissions reduction. We show that the revenue raised from these reforms can be recycled in a way that ameliorates some of the distributional concerns. Whilst such recycling is not able to protect all poorer households, existing policy also makes distributional trade‐offs, but does so in an opaque and inefficient way.     

Combining input-output analysis and micro-simulation to assess the effects of carbon taxation on Spanish households

This paper explores the effects of a tax levied on Spanish energy-related CO2 emissions. After justifying the relevance of carbon taxation in the Spanish context, we consider the introduction of a product (fossil-fuel) tax with a rate obtained through the ‘actual damage cost’ method. Our empirical analysis proceeds in two stages. First, we employ an input-output demand model to calculate the price changes after the introduction of carbon taxation. In a second stage, simulation with Spanish household micro-data for 1994 yields the environmental and economic effects of a Spanish carbon tax. We find a limited short-run reaction to the carbon tax, which hampers its environmental success. The carbon tax burden is, however, significant, with a proportional distribution across households.

Economic Instruments to Improve UK Home Energy Efficiency without Negative Social Impacts*

The research examined how to use economic instruments to reduce carbon emissions from the UK housing sector without causing negative impacts on the poorest households. Carbon taxes would worsen the problem of fuel poverty. Compensation mechanisms involving the tax and benefit system were examined, but found not to be entirely effective because of the enormous range in the existing energy efficiency of homes. Exemptions for low‐income households were examined, but found impractical to target. It was concluded that the best way to use economic instruments was through a scheme involving energy audits and surcharges to council tax and stamp duty for homeowners who failed to make cost‐effective energy efficiency improvements within a specified time, with grants and loans to assist low‐income households. After the implementation of such a scheme for 10 years, it would be practical to introduce a targeted carbon tax.     

Tax Incidence in Madagascar: An Analysis Using Household Data

This article discusses tax incidence in Madagascar and askswho pays the taxes that finance government spending. Its mainconcern is to identify the progressivity of different taxeslevied in Madagascar, based on the consumption and income patternsfound in the 1994 Enquête Permanente auprès desMénages, a nationally representative survey. The resultssuggest that most taxes are progressive, meaning that wealthyhouseholds pay proportionately more of these taxes relativeto their expenditures than do poor households. Two notable exceptionsare taxes on kerosene and export duties on vanilla, both ofwhich are regressive. These results are consistent with thoseof a study of Ghana, the only other comparable research on taxincidence in Africa. That study found taxes on kerosene andcocoa exports to be the most regressive taxes in Ghana. Making firm policy recommendations for tax reform would requirean analysis of the economic efficiency and administrative efficacyof different taxes to complement this article's work on theirequity implications. Nevertheless, the results suggest thatthe movement away from trade taxes, especially export duties,and toward broadly based value added or income taxes would bemore equitable and more economically efficient. The only legitimateimpediment to such reforms in Madagascar is administrative,that is, the government's ability to collect different taxeseffectively. Although administrative efficiency may be a problemfor value added or income taxes, taxes on petroleum products(except kerosene) are highly progressive and provide a goodtax handle.     

Redistributive impact of indirect tax reforms: Greece, 1988–2002

This paper assesses the distributional impact of indirect taxes among Greek households between 1988 and 2002, a period that coincides with the introduction of significant reforms in the tax system due to EU membership. The highly differentiated indirect tax structure prevailing at the beginning of the period had distributional benefits over the more simplified 2002 tax structure. The overall inequality of the after‐tax welfare distribution has increased by 6–12½ per cent and changes in the indirect tax system seem to explain about half of this increase. The paper also applies a recent method of measuring the distributional impact of relative price changes caused by changes in tax rates of commodities (Newbery, 1995) and establishes that indirect tax reforms introduced since 1988 had an adverse impact on the distribution of purchasing power, which nevertheless seems to be very small.     

Risk perception and worry in environmental decision-making – a case study within the Swedish steel industry

Sustainable development is an important issue for the industry in order to fulfil legislation requirements and to be able to use green marketing as a competitive advantage. The Swedish steel industry has implemented a large number of environmental improvements, for example, within energy efficiency, raw materials and recyclability. Technical improvements can help the industry decrease its environmental impact; however, in order to reach sustainable development, more factors need to be considered: an effective environmental decision-making process, for example. This process may be influenced by personal factors such as risk perception and worry, which are factors that will not contribute to an effective decision-making process. The aim of this study was to investigate if personal worry and risk perception influenced environmental decision-making within the Swedish steel industry. Thirty-eight interviews were performed at 10 Swedish steelworks using the Q-methodology. The major perceived environmental risks with the facility and personal worry were assessed, compared to the day-to-day work. It was concluded that the major perceived risks were emissions of carbon dioxide, use of non-renewable energy and emissions of particulate matter. The decision-makers were mainly worried about emissions of carbon dioxide, emissions of dioxin and use of non-renewable energy. The environmental issues that were prioritised in practice (day-to-day work) were emissions of carbon dioxide, emissions of particulate matter and emissions of metals. Even though emissions of carbon dioxide were given the highest priority in the Q-sorts, there was in general no clear relationship between risk perception and personal worry with the prioritised environmental issues at the steelworks. The quantitative analysis of the Q-sorts and the qualitative interviews both showed that the day-to-day work was unaffected by personal worry and risk.     

Incomes,Incentives and the Growth of Means-Testing in Hungary

The purpose of this paper is to examine the reform of family benefits and the growth of means-testing in Hungary. From 1996, many family benefits were means-tested for the first time. A new microsimulation model for Hungary, running on recent survey microdata, is used to simulate the impact of the 1996 reforms on government expenditures, the distribution of incomes, the targeting of benefits and effective marginal tax rates. These reforms are found to be largely benign and even progressive, but they also appear to be paving the way for the further extension of means-testing. The model is used to investigate such an extension by simulating the impact of a UK-style system of means-tested family benefits in Hungary. This system achieves some expenditure savings and better targeting of benefits, but also greatly increases effective marginal tax rates on low-income households with children. The paper argues that resulting poverty traps may increase child poverty in Hungary in the longer term and cautions against the overextension of means-testing.     

Reforming the Direct–Indirect Tax Mix

This paper provides a new framework for evaluating the welfare effects of commodity tax reforms. It is shown that tax reforms are welfare improving if and only if they satisfy the following intuitive property: on average, consumer prices fall for commodities with high marginal excess burdens. The rule is then applied to analyze a shift from differentiated commodity taxation to direct flat-rate taxation of labour income. The welfare impact of such reforms can be decomposed into two effects: (i) the increase in welfare associated with substitution among taxed commodities, and (ii) the loss in welfare associated with substitution between commodities and leisure. On balance, a shift towards direct taxation is desirable when inter-commodity substitution effects are large relative to commodity–leisure substitution effects. The analysis allows us to reconcile the apparently conflicting results of the tax reform and optimal taxation literatures.     

Pro-poor indirect tax reforms,with an application to Mexico

This paper proposes a methodology for testing for whether tax reforms are pro-poor. This is done by extending stochastic dominance techniques to identify tax reforms that will be deemed absolutely or relatively pro-poor by a wide spectrum of poverty analysts. The statistical properties of the various estimators are also derived in order to make the method implementable using survey data. The methodology is used to assess the pro-poorness of possible reforms to Mexico’s indirect tax system. This leads to the identification of several possible pro-poor tax reforms in that country. It also shows how the pro-poorness of a tax reform depends on one’s conception of poverty as well as on the revenue and efficiency impact of the reform.     

Gender implications of current social security reforms

This paper examines some current reforms to social security benefits / tax credits and changes to employment provisions from a gender perspective. It analyses tensions between the trend towards ‘individualisation’ and growing emphasis on the couple/household as a policy focus. New tax credits change the distribution of resources within many couples. Incentives to work for some second earners should improve; but extending in‐work subsidies to childless couples raises questions. Payment of child tax credit to the ‘main carer’ has been welcomed, though the implications of joint ownership of tax credits are unclear, and joint assessment will be extended. Many claimants' partners can now access employment services. However, this is aimed at reducing the number of workless households rather than expanding individuals' opportunities. Joint claims for jobseeker's allowance, and work‐focused interviews, involve increased responsibilities for partners but no right of access to individual income. A more consistent critical analysis of reform from a gender perspective is required.     

Tax reforms and the capital structure of banks

This paper studies the link between corporate income tax (CIT) reforms and domestic banks’ financing decisions. We use a dataset of CIT reforms and estimate the effect of tax rate changes on leverage, dividend policies and earnings management of banks. The results suggest that taxation influences all three variables. Leverage increases with the CIT rate in the first three years after the reform. The reason is that the statutory CIT rate determines the value of the debt tax shield. A higher tax rate increases incentives to use debt finance when interest payments are deductible from the CIT base. The tax effects we find are statistically and economically significant but considerably lower than those found in previous research. Also, dividend pay-outs increase after an increase in CIT rates. This could indicate that banks actively manage their pay-out policies around tax reforms and adjust their capital structure with changes in dividends. Furthermore, banks increase loss loan reserves in anticipation of tax rate cuts since losses become less valuable with lower CIT rates.     

A CGE Analysis of the Impacts of a Carbon Tax on Provincial Economy in China

This article conducts a computable general equilibrium (CGE) model to investigate the impacts of a carbon tax on economy at province levels in China since China features significantly differentiated development modes across regions. Three representative provinces including Henan, Fujian, and Chongqing are selected as the sample. The empirical results indicate that carbon tax is an efficient policy to reduce carbon emissions accompanied with negative impact on provincial economy. To cushion the negative impacts of carbon tax, a moderate carbon tax rate and carbon tax recycling policy are recommended according to the simulation results.     

Crowding out in Ricardian economies

The crowding-out coefficient is the ratio of the reduction in privately-issued bonds to the increase in government bonds that are issued to finance a tax cut. If (1) Ricardian Equivalence holds, and (2) households do not borrow risklessly while holding positive gross positions in other riskless assets, the crowding-out coefficient equals the fraction of the aggregate tax cut that accrues to households that borrow. In the conventional case in which all households receive equal tax cuts, the crowding-out coefficient equals the fraction of households that borrow; in the United States, about 75% of households borrow, so the crowding-out coefficient is predicted to be 0.75. Allowing for cross-sectional variation in tax changes increases the crowding-out coefficient to about 0.85.     

Food prices,tax reforms and consumer Welfare in Tanzania 1991–2007

This paper analyses the effect of observed food price changes on household consumption (welfare) in Tanzania and from this simulates the welfare effect attributable to tax (tariffs and VAT) reforms. The three rounds of the Tanzania Household Budget Survey (1991/92, 2000/01 and 2007) are used to apply Deaton’s method based on median unit values (prices) and household budget shares. The results indicate that real price increases over 1991–2007 have reduced welfare of the average household by 20 per cent of 1991 income, and the loss was fairly evenly distributed between the 1990s and 2000s. The welfare loss was much greater for the poor, especially the rural poor (a 27 per cent reduction), compared to the non-poor (in particular the urban non-poor, who suffered a five per cent loss). Although we cannot establish explicit links between tax reforms and domestic commodity price changes, to assess the extent to which welfare changes can be explained by tax reforms we simulate the effects of tax changes on domestic price changes. The simulation shows that tax reforms (tariff reductions) offset the welfare losses for all household groups, especially in the 1990s; although the differences were small, the urban poor benefit more in relative terms from tax reforms whereas the rural poor benefit least (the effect on the non-poor was similar irrespective of location).     

Dividend and capital gains taxation under incomplete markets

Motivated by the Jobs and Growth Tax Relief Reconciliation Act (JGTRRA) of 2003, the effects of capital income tax cuts are investigated in an economy with heterogeneous households and a representative, mature firm. Dividend tax cuts, contrary to capital gains tax cuts, lead to a decrease in investment and capital. This is because they increase the market value of existing capital and households require a higher return to hold this additional wealth. In line with empirical evidence, the model predicts substantial increases in dividends and stock prices. Overall, the tax cuts lead to a welfare reduction equivalent to a consumption drop of 0.5%.     

Causes,benefits, and risks of business tax incentives

This paper provides an updated overview of tax incentives for business investment. It argues that tax competition is likely to be a major force driving countries’ tax reforms, and discusses tax incentives as a possible response to this. This is complemented by more detailed arguments for and against tax incentives, and by an illustrative analysis of different incentives using effective tax rates. Findings from the empirical literature on tax incentives are also presented. Based on the overview of theoretical and empirical findings, the paper then suggests a matrix of criteria to determine the usefulness of different tax incentives depending on a country’s circumstances.

An Efficiency Analysis of Consumption and Production Taxation with an Application to Value-Added Taxation

The usual arguments pro destination-based, consumption-oriented or pro origin-based, production-oriented VAT are found wanting. They largely ignore tax effects on locational choices of firms. This paper provides a comparison of consumption and production taxation within a model of firm and household mobility. It is shown that the case for consumption taxation becomes stronger when profit taxes are not available. The consumption tax is the more targeted instrument when households are to be induced to locate efficiently. It is argued that, with border controls lacking, the alternative option should be seen more in a wage tax and less in a production tax.     

Does the market value greenhouse gas emissions? Evidence from multi-country firm data

Despite increasing global attention on corporate carbon emissions, few studies have examined the value relevance of carbon emission information in the international context. This paper examines whether carbon emission information voluntarily disclosed by a firm affects its market value. After controlling for a firm's likelihood to provide voluntary carbon disclosures, we find that the level of carbon emissions is negatively related to firm value. This negative impact is more prominent for firms in countries that have a national carbon emission trading scheme and stringent environmental regulations. Furthermore, corporate governance is found to reduce the negative value effect of carbon emissions, indicating that shareholders have favorable perceptions regarding the carbon management ability of firms with good corporate governance. Cultural contexts such as uncertainty avoidance and long-term orientation also affect the value effect of risks and future liabilities associated with carbon emissions. We find that the value-decreasing effect of carbon emissions is weaker in countries characterized by high uncertainty avoidance and long-term orientations.
