Economic and environmental efficiency using a social accounting matrix

This paper aims to show the utility of the so-called Social Accounting Matrix and Environmental Accounts (SAMEA) for economic and environmental efficiency analysis. The article uses the SAMEA for Spain in 2000, applied to water resources and greenhouse gas emissions. This matrix is used as a central core of a multisectorial model of economic and environmental performance, and it calculates the denominated “domestics SAMEA multipliers” and their decomposition into characteristic, direct, indirect and induced effects. These multipliers show some evaluation of economic and environmental efficiency. Also, we present an application of these multipliers that demonstrates that there is no causal interrelation between those sectors with higher economic backward linkages and those with higher environmental deterioration backward linkages.     

Water accounting in Australia

This paper introduces water accounting as produced by the Australian Bureau of Statistics (ABS). It provides information about the ABS Water Accounts and highlights the many other organisations involved in the provision and use of water related data in Australia. The ABS Water Accounts have built upon previous reports on Australian water resources and the System of Environment and Economic Accounting [UN (United Nations) 2003. Draft Handbook Integrated Environmental and Economic Accounting. Studies in Methods, Series F, No. 61, Rev. 1. United Nations, European Commission, International Monetary Fund, Organisation for Economic Cooperation and Development, World Bank. New York.]. Information from the ABS Water Accounts is presented along with examples of their use in economic analyses designed to inform public debate and government decision-makers.A key feature of the Australian environment is that water is relatively scarce when compared with other inhabited continents. Rainfall displays a high level of spatial and temporal variability and droughts are common. In 2004 an Intergovernmental Agreement on a National Water Initiative (NWI) was reached by Australia's national and eight state and territory governments. The NWI aims to address environmental, economic and social concerns about the current and future state of Australia's water resources. The NWI specifically calls for the preparation of annual water accounts, which clearly indicates the expected usefulness of national and regional water accounts.     

TAKING THE ENVIRONMENT INTO ACCOUNT: THE NAMEA APPROACH

The National Accounting Matrix including Environmental Accounts (NAMEA) shows environmental burdens that are consistent with the economic figures in the national accounts. In the NAMEA, the existing national accounts matrix has been extended with accounts in physical units. On the basis of the expected contribution of each polluting substance to a particular environmental problem, emissions are converted to theme equivalents. This results in six summary environmental indicators that are directly comparable to the conventional economic aggregates. In addition, this meso-level information system can be used as the core data framework for integrated analyses and forecasts of economic and environmental changes.     

Environmental impact of household activity in Spain

The objective of this paper is to analyse the environmental impacts of the Spanish economy by way of water and atmospheric pollution on the basis of a Spanish Accounting Matrix for 1999. Only households were taken as an exogenous account. The pollution measures are estimated for seven categories of pollution: three atmospheric pollutants (CO₂, NO_x and SO_x) and four indicators for water (waste water, nitrogen, metals and biological oxygen demand (BOD)). The environmental data base was obtained from the Spanish Statistical Institute.The analysis reveals that pollution in Spain is closely linked to food production, energy, extractive industries and paper manufacturing. We show that services, taken as a whole, are major polluters, though this is due to the volume of household expenditure they represent rather than their pollution potential as such. We also show that the Spanish economy avoids a great deal of pollution by importing inputs, which pollute where they are produced. Finally, the study also provides per capita pollution values for the aforementioned seven pollutants.     

Regional double dividend from environmental tax reform: An application for the Italian economy

The greenhouse effect forces national Governments to design environmental tax policies for facing not only global warming but also the negative economic consequences resulting from the reduction of emissions such as a negative change of GDP. This paper aims at verifying the impact of an environmental fiscal reform able to attain both the reduction of greenhouse gas emissions and the regional double dividend. We have decided to follow the computable general equilibrium approach for modelling the multisectoral income circular flow in the case of a bi-regional economy as described by a Social Accounting Matrix we have built for this purpose. The tools of analysis we chose represent suitable and consistent instruments in order to quantify the effects of an environmental tax reform. They can in fact highlight the possible differences in responses between macro regions in terms of regional GDP changes, regional prices and regional employment rate. In fact, the extended multi-sectoral framework, on which the model is developed, represents economic activities, imperfect labour market and institutional sectors behaviours in each macro region. The simulations performed concern the introduction of a progressive and proportional green tax on each type of commodity according to the corresponding level of CO₂ emissions. Furthermore all simulations introduce a recycling scheme of green tax revenues, whose aim is reducing both the income tax and the regional tax on activities (IRAP). The application is done on a bi-regional Social Accounting Matrix for Italy for the year 2003.     

Material and energy flow accounting in Germany—Data base for applying the national accounting matrix including environmental accounts concept

In this paper, we discuss the background of German Environmental Economic Accounting (GEEA). One of the elements of GEEA is material and energy flow analysis. The corresponding accounts are presented in the Material and Energy Flow Information System (MEFIS). This data base can be used for many purposes including application in the National Accounting Matrix including Environmental Accounts (NAMEA). The data availability for analyzing particular environmental burdens is described. Specific indicators for greenhouse effect and acidification are presented in the form of charts and tables.     

Estimating a socially optimal water price for irrigation versus an environmentally optimal water price through the use of Geographical Information Systems and Social Accounting Matrices

This article develops a method for establishing water prices and their effects in order to provide policy makers an environmentally and socially optimal range of regional prices for irrigation water. Two prices are determined. The “environmentally optimal price” of water is defined as the one that internalizes the environmental costs generated by agricultural consumption. The “social optimally price” of water is defined as the one that maximizes levies on water for agriculture without affecting the regional economy. The environmentally optimal price is calculated with an economic model built over a Geographical Information System (GIS) that allows the economic quantification and valuation of the environmental cost of water in different basins. The optimal price is calculated with a demand curve for irrigation water introduced into a Social Accounting Matrix (SAM) to observe if the regional economy can accept higher prices without affecting the regional GDP. Potential water prices are established, ranging from prices that minimize the negative impact in the regional economy to those that totally internalize the environmental cost of water.     

On the international harmonisation of environmental accounting: comparing the National Accounting Matrix including Environmental Accounts of Sweden,Germany, the UK,Japan and the Netherlands

This article presents a preliminary comparison of the systems of integrated economic and environmental accounts in Sweden, Germany, the UK, Japan and the Netherlands. These countries have presented their results in a National Accounting Matrix including Environmental Accounts (NAMEA). Although the first Dutch NAMEA may have served as an example, for each country different features can be found depending on differences in objectives, available statistical sources and subsequently institutional backgrounds. Moreover, most countries have developed the NAMEA simultaneously with other accounting approaches. The first section compares differences in objective, scope and methods. The second section presents an preliminary comparison of the results which shows that comparable accounts will not automatically lead to comparable results.     

AGE analysis of the impact of a carbon energy tax on the Irish economy

A computable general equilibrium model with specific detail in taxation and energy use is developed in this paper to quantify the impact of the implementation of energy taxation to reduce carbon dioxide emissions in Ireland. Benchmark data combining physical energy and emissions data and economic data in the form of a Social Accounting Matrix (SAM) had to be compiled from various data sources, because energy and pollution accounts from the SEEA are not available for Ireland. We find that the reduction target for energy related CO₂ emissions in Ireland of 25.8% compared to 1998 levels can be achieved with a carbon energy tax of 10-15 euros per tonne of CO₂. Though fuel switching is important in meeting the target, this result is more sensitive to the possibilities for producers to substitute away from energy use. Welfare would fall but only by small percentages. Production and consumption patterns would change more significantly, with a shift in demand from fuels with a high emission factor to energy sources with a lower carbon-intensity and from energy to other commodities. This paper confirms that a carbon energy tax leads to greater emission reductions than an equivalent uniform energy tax. The latter has a stronger negative impact on the less polluting energy sectors whereas the carbon tax greatly stimulates the use of renewable energy and reduces the use of peat and coal. The new SAM, the model and the application to energy taxes contribute to a better informed debate on environmental policy in Ireland.

A social accounting matrix for Egypt, 1976

A 1976 Social Accounting Matrix for Egypt is presented and the methods of estimation used are described briefly. Some of the implications of the accounting are discussed. The information on the distribution of taxes and subsidies indicates that the latter are the major source of progressiveness in the fiscal system. In relation to their incomes, rural households are also shown to pay less in taxes and receive less in subsidies than urban households.     

Assessing the economic impact of entrepreneurship on a regional economy using social accounting matrices: the case of Andalusia

This article analyses the impact that entrepreneurial activity has, from the economic point of view, on a regional economy (Andalusia), based on a Social Accounting Matrix linear model. Moreover, to measure entrepreneurship at regional level, it is defined what can be considered an entrepreneurial initiative company from a quantitative point of view. The results obtained, in terms of Production, GDP and job creation, show how entrepreneurship, in the case of Andalusia, contributes to the sustainability of the economy, its growth and, above all, the reduction of unemployment in the short term.     

IMPACT OF TRADE SANCTIONS ON SOUTH AFRICA: A SOCIAL ACCOUNTING MATRIX APPROACH

This paper discusses a new approach for studying sanctions based on multipliers derived from the Social Accounting Matrix. I apply the methodology to the South African case and discuss output effects and distributional impacts on factors and households. The results show that the effects of trade sanctions on the South African economy are significant.     

RELATIVE INCOME DETERMINATION IN THE UNITED STATES: A SOCIAL ACCOUNTING PERSPECTIVE

The disaggregated nature of a Social Accounting Matrix makes it a suitable tool for studying the income generation process and its distributional effects. Using the linear structure of a SAM, a model for distributional analysis is developed. The proposed approach emphasizes the functional determinants of relative incomes and the underlying structural features of income distribution and redistribution.     

Socio-economic impact of a nuclear power plant: Almaraz (Spain)

An analysis is made of the socio-economic impact in a region in which a nuclear plant is decommissioned. The average age of nuclear power plants around the world is high, so that many are close to the end of their useful life. The issue of this impact will be important in a few years for various reasons, especially because those plants tend to be drivers of the economic activity in the areas in which they are located. The focus of this communication is on these socio-economic effects. Methodologically, socio-economic analysis uses a linear Social Accounting Matrix model that improves traditional Input–Output approaches by covering the induced effects generated from the receptors of income out to other sectors of the economy. The procedure is applied to an empirical analysis of the Almaraz Nuclear Power Plant in Spain. This was purposely chosen as sharing many of the general characteristics of nuclear plants around the world. If the plant is closed down, our results suggest that there will be a clear negative impact in terms of employment and added value generation.     

Accounting for Environmental Services: Contrasting the SEEA and the ENRAP Approaches

Both the System of Integrated Environment and Economic Accounting (SEEA) and the Environmental and Natural Resources Accounting Project (ENRAP) are efforts to expand conventional national economic accounts in order to better reflect interactions between the market economy and the natural environment. In order to maintain a close relationship to the System of National Accounts (SNA) accounting standards, SEEA adopts conventional definitions of productive sectors. However, SEEA fails to account for many valuable services of the natural environment and encourages the use of techniques that provide misleading and poor estimates of depreciation and damage to the environment. ENRAP addresses these deficiencies by explicitly recognizing that the natural environment is a productive economic sector. ENRAP encourages the use of imputation approaches that draw on techniques common in the environmental economics literature. These approaches are consistent with definitions of depreciation and environmental damage widely accepted in economic theory. The principles that underlie the ENRAP approach provide a basis for contrasting ENRAP and SEEA empirically. Using Philippine data, SEEA-type estimates are compared with those of ENRAP.     

用能技术还是管理技术？——绿色技术创新发生环节和类型的抉择

为厘清环境规制对企业绿色技术创新的影响及其机理,本文从企业绿色技术创新发生的环节和类型的视角切入,将企业绿色技术创新分为用能技术创新和管理技术创新两大类及其下设的七小类,并将之在生产链环节（源头、过程和末端）上加以归类,通过匹配沪深A股上市公司、《中国环境统计年鉴》和《中国工业经济统计年鉴》获取了关于环境规制和企业绿色技术创新的指标,研究了环境规制约束下企业技术绿色创新的抉择。结果发现：第一,环境规制整体上未对企业绿色技术创新有明显促进作用,“创新补偿”效应难以成立;第二,其内驱因素是,环境规制显著降低了企业生产率和收益率;第三,其外部原因是,与低污染行业企业相比,环境规制对高污染行业企业的绿色技术创新有一定促进作用,体现在用能技术创新、管理技术创新两方面,并分布在生产链的源头、过程及末端三个环节;第四,其外部原因还包括环境规制作用的阶段性,环境规制对个别绿色技术创新指标造成了先促进后抑制的影响,也影响了“创新补偿”效应的成立。据此,本文对环境规制约束下企业绿色技术创新的激励和选择提供一定启示。     

Policy impact assessment in developing countries using Social Accounting Matrices: The Kenya SAM 2014

This paper describes the structure and estimation of a Social Accounting Matrix (SAM) of Kenya for the year 2014. Among its specificities, this SAM includes a very high disaggregation of the agri‐food sector and accounts for the double role of households as producers and consumers. Accounting for these characteristics is crucial to provide robust socioeconomic analysis in the context of developing countries. Indeed, this type of database is valuable to perform ex‐ante evaluations of economic policies with various economic models and techniques. In this paper, we present an application with a linear multiplier analysis (backward linkages and value chain decomposition). The results show the capacity of the primary sector in Kenya to generate value added and employment, with this growth distributed more intensely in rural households whose main livelihood is semi‐subsistence agriculture.     

THE ESTIMATION OF PRICE EFFECTS IN A SOCIAL ACCOUNTING MATRIX

The estimation of true basic prices in a Social Accounting Matrix (SAM) has long been recognized as necessary in order to achieve uniform valuation of inputs for meaningful manipulation of the input-output table contained in a SAM, in order to assess the real effects of changes in demand, etc. In practice, approximate basic prices only have normally been calculated in order to avoid matrix inversion among other things. It is equally the case that true basic prices are required if one wishes to assess the price-raising effects of commodity taxes. It is shown through an example that approximate basic prices, as conventionally calculated, are inadequate and potentially misleading for this as indeed they are for achieving uniformity of valuation. There are also problems with the present procedure for calculating true basic prices.
An alternative method of calculating true basic prices is given, which has various advantages over the existing method, and a new approximate method is also derived which appears to represent a definite improvement on the present method. For the main purpose of the paper, however, the prices of concern are those charged by producers to which the methodology equally applies.
