the carbon footprint of uk households 1990 2004 a socio economically disaggregated quasi multi regional input output model this paper presents a socio economically disaggregated framework for attributing co2 emissions to people s high level functional needs based around a quasi multi regional input output qmrio model the study in theory takes into account all co2 emissions that arise from energy used in production of goods and services to satisfy uk household demand whether the emissions occur in the uk or abroad results show that co2 emissions attributable to households were 15 above 1990 levels in 2004 and that although absolute decoupling occurred between household expenditure and co2 during the uk s switch from coal to gas in the early 1990s since then only slight relative decoupling is evident the proportion of co2 that arises outside uk borders in support of uk consumption is rising and reducing these emissions is particularly problematic in a global trading system investigation into the carbon footprint of different segments of the uk population shows wide variation the segment with the highest carbon footprint emits 64 more co2 than the segment with the lowest results show that recreation and leisure are responsible for over one quarter of co2 emissions in a typical uk household in 2004 we conclude that expanding lifestyle aspirations are significant factors in driving household co2 emissions but the study also emphasizes that attention must be paid to the infrastructures and institutions that result in considerable amounts of co2 being locked up in basic household activities through which people meet their everyday needs for subsistence protection and communication with family and friends the findings highlight the sheer scale of the challenge facing uk policy makers and suggest that policies should be targeted towards segments of society responsible for the highest carbon footprints

the political economy of financial reform are abiad and mody right motivated by the questions financial reform what shakes it what shapes it raised by abiad and mody 2005 this paper studies the forces that induce governments to undertake financial sector reform rather than their ordered logit technique it uses a within groups approach allowing for error dependence across countries and over time this analysis shows that some of the am findings are not robust to error dependence and the estimation method it has shed new light on the political economy of financial reform copyright 2009 john wiley sons ltd

political institutions and financial development an empirical study summary this paper examines whether political institutional improvement promotes financial development using a panel dataset of 90 developed and developing countries over 1960 99 the empirical evidence reveals a positive effect of institutional improvement on financial development at least in the short run particularly for lower income countries the preliminary evidence by a before after event study indicates that a democratic transformation is typically followed by an increase in financial development

from production based to consumption based national emission inventories abstract under the united national framework convention of climate change unfccc countries are required to submit national emission inventories nei to benchmark reductions in greenhouse gas ghg emissions depending on the definition and system boundary of the nei the mitigation options and priorities may vary the territorial system boundary used by the unfccc has been critiqued for not including international transportation and potentially causing carbon leakage to address these issues past literature has argued in favour of using consumption based nei in climate policy this article discusses several issues in moving from the standard production based nei to consumption based nei first two distinct accounting approaches for constructing consumption based nei are presented the approaches differ in the allocation of intermediate consumption of imported products second a consistent method of weighting production based and consumption based nei is discussed this is an extension of the previous literature on shared responsibility to nei third due to increased uncertainty and a wide system boundary it may be difficult to implement consumption based nei directly into climate policy several alternative options for incorporating consumption based inventories into climate policy are discussed

embodied carbon in trade a survey of the empirical literature this paper critically reviews the literature on embodied carbon in trade and evaluates our present empirical understanding of these flows a careful comparison of quantitative results from this literature exposes significant inconsistencies for instance estimates for emission embodied in world trade in 2004 range between 4 4 gt and 6 2 gt co2 the difference corresponding to around half of europe s annual emissions a few consistent themes do nevertheless emerge from the literature most importantly emissions in trade constitute a large and growing share of global emissions uncertainty about country level embodied emissions remains large however which presents severe limitations for the practical application of embodied carbon principles in climate policy

crisis in the eye of the beholder economic crisis and partisan politics in latin american and east european international monetary fund programs this article analyzes the interaction between economic crises and partisan politics during international monetary fund program initiation in latin america in the 1980s and eastern europe in the 1990s the author argues that economic crises are at least in part in the eye of the beholder and therefore policy responses reflect the interaction between crisis intensity and the government s partisan interpretation of the crisis which in turn depends on the nature of the economic crisis and its broader regional and international environment using cross country statistical evidence from the two regions the article shows that certain types of crises such as liquidity shortfalls elicit similar responses across the ideological spectrum and regional contexts by contrast debt repayment and domestic crises are more prone to divergent ideological interpretations but the extent of partisan divergence is context sensitive in that it occurred during the latin american debt crisis but not in the post communist tra

carbon leakage from unilateral environmental tax reforms in europe 1995 2005 abstract studies of the effects of the kyoto protocol have shown carbon leakage typically from tax and permit schemes with lump sum revenues recycling to be in the range of 5 20 using static computable general equilibrium models however in practice researchers have found that carbon leakage from the implementation of the eu ets is unlikely to be substantial because transport costs local market conditions product variety and incomplete information all tend to favour local production this study investigates potential carbon leakage from six eu member states mss that implemented environmental tax reform etrs unilaterally over the period 1995 2005 the study uses the large scale multisectoral integrated energy environment economy e3 model of 27 european countries energy environment economy model of europe e3me to undertake a dynamic comparative analysis to assess any carbon leakage effects over the longer term 1995 2012 a counterfactual reference case is constructed assuming that the six countries did not introduce etrs then alternative scenarios are developed to assess the effects of the etrs including effects on co2 emissions for the eu25 economies most mss recorded a reduction in co2 emissions when comparing the baseline case to the reference case the results show that carbon leakage is very small and in some cases negative due to technological spillover effects

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

energy requirements of sydney households supporting the lifestyles of the populations of modern cities requires vast quantities of natural resources and leads to environmental stresses such as air and water pollution research into the metabolism of cities therefore aims at understanding the physical flows into within and out of cities with a view to reducing the use of resources and the environmental impacts one important physical indicator is energy use most studies on cities only consider direct or end user energy consumption since the function of cities is to serve the lives of their residents indirect energy use in cities or energy embodied in the consumption of goods and services by its residents can be regarded as being as important as direct energy use however physical models of cities are extremely complex and have difficulty in dealing with boundary issues and hence the indirect resource requirements in this paper we use input output analysis and detailed household expenditure data to yield comprehensive energy use breakdowns for the 14 statistical subdivisions of sydney multivariate regression and structural path analysis spa are used to interpret the results clear correlations can be drawn between energy use and income household size age and degree of urbanity the structural path analysis is used to demonstrate how significant differences in lifestyles between inner and outer areas of sydney leads to different energy use characteristics this final consumption based approach to analysing the energy requirements for households has important implications for measures aimed at reducing energy use which tend to only consider direct energy use d 2004 elsevier b v all rights reserved

industrial policy choice during the crisis era using an extensive database of non macroeconomic state interventions implemented since the global economic crisis began this paper provides quantitative evidence on the resort to selectivity by several major economic powers the propensity to promote certain sectors certain firms within sectors and domestic over commercial interests is contrasted across jurisdictions at least one prominent contention in the industrial policy literature is not borne out in the data and certain cross country and cross sectoral variations found here could benefit from further analysis a crisis era shift towards selectivity and away from the level playing field can be detected in the major trading nations

the benefit of crises for economic reforms when expenditures consistently outrun revenue the resulting inflation may have the effect of convincing the public and government that taxes must be raised to finance public investment in the advanced industrial countries income taxation and big spurts in taxation generally have become possible only under the impact of major emergency and crisis mostly in wartime in a number of developing countries in

why and when do governments initiate public enterprise reform initiating public enterprise reform is a complex decision influenced by economic factors as well as the ideological biases and personalities of political leaders nevertheless the use of a contracting framework yields important generalizations about what drives the decision this article argues that the decision depends fundamentally on the potential efficiency gains from the reform and its associated transactions costs costs arise because of asymmetries in information and opportunism problems that usually plague contract negotiations the article identifies observable variables that may affect either the potential gains or the transactions costs uses them to construct a simple probit decision making model and tests the model using data from fifteen developing countries over a twenty year period

specification and aggregation errors in environmentally extended input output models this article considers the specification and aggregation errors that arise from estimating embodied text co 2 emissions and embodied water use with environmentally extended national input output io models instead of with an environmentally extended international io model model specification errors result from the use of domestic environmental and domestic technology coefficients to estimate emissions or resources that are embodied in international trade for text co 2 footprints unacceptably large overestimations arise from using domestic emission coefficients which are only partly canceled out by using domestic technology coefficients for water use footprints both specification errors are smaller but hardly cancel out sectoral aggregation errors occur when combining the 129 exiopol industries to 59 eu industries and 10 broad sectors the latter aggregation creates the largest errors spatial aggregation errors arise from combining 43 individual exiopol countries in four broad regions and the rest of the world substantial unacceptable errors occur again now especially in relation to water use

long live democracy the determinants of political instability in latin america abstract we investigate the underlying causes of political instability in a panel of 18 latin american countries from 1971 2000 we test whether regime type regime durability factionalism income inequality ethnic diversity ethnic discrimination regional spillover effects urban growth and macroeconomic variables matter for instability we find several important results 1 democracy has a significant negative effect on instability that is robust to several alternative specifications 2 factionalised political systems experience higher instability 3 income inequality ethnic fractionalisation and urban growth have important nonlinear effects on instability and 4 of the macroeconomic variables we study only openness to trade has a significant negative effect on instability

when do governments improve fiscal institutions lessons from financial crisis and fiscal reform in latin america do crises really lead to more institutional reforms this paper explores the connection between financial crises and one type of reform frequently advocated during the recent global financial crisis namely fiscal institutional reforms some authors expect that crises lead to reforms but we demonstrate that the relationship is not so straightforward using a data set of latin american countries that experienced several crises and also several periods of reform in the period from 1990 to 2005 we find that the type of crisis and its duration matter we argue that reforms are less likely during a banking crisis whereas fiscal crises are most likely to lead to fiscal reforms this means that the type of economic crisis is important for explaining the likelihood of reforms we explore other possible explanations for reform such as the partisanship of the president and whether a country is under an imf program and do not find confirming evidence for alternative explanations

the political economy of financial reform how robust are huang s findings using new data on financial liberalization taken from abiad et al 2008 imf working papers no 08 266 for 62 countries over the period 1975 2005 we show that some of the main findings of huang s 2009 journal of applied econometrics 24 1207 1213 replication study on the drivers of financial liberalization are not robust major changes concern the effect of democracy on financial reform and the supposed relationship between the desired level of financial liberalization and a country s per capita income copyright c 2012 john wiley sons ltd

why do crises go to waste fiscal austerity and public service reform in the tight budgetary conditions following the 2008 financial crisis governments have proposed saving money by reforming public services this paper argues that tight budget constraints make reform harder by introducing an information problem governments are uncertain about bureaucratic departments effectiveness normally effective departments can be identified by increasing their budget since they can use the increase to produce more than ineffective departments can when budgets must be cut however ineffective departments can mimic effective ones by reducing their output budget cuts thus harm both short run productive efficiency and long run allocative efficiency i confirm these predictions in a us dataset low marginal productivity bureaucracies reduce output by more than expected in response to a budget cut and budget setters respond less to observed short run marginal productivity after cutback years

the reliability of u s gross national product two aspects of reliability revisions and errors need separate analysis revisions in gross national product gnp estimates are large in relation to the size of changes that matter to businesses and policy makers nevertheless preliminary estimates convey a lot of information about what the revised estimates will show errors in gnp estimates can plausibly be either larger or smaller than revisions the distinction between gathering errors and adjustment errors helps us understand a the absence of any measure of the size of gnp errors and b the ways in which national income statisticians go about reducing errors these ideas suggest several guidelines for improving gnp estimates

a carbon footprint proportional to expenditure a case for norway abstract motivated by the importance of consumption as an underlying driver of co 2 emissions we examine the link between consumption and co 2 emissions for norwegian households the main goal is to investigate whether there is a decoupling of consumption expenditures and the environmental impact as we move up the income ladder by combining a 2007 norwegian consumer expenditure survey with emission coefficients from an environmental input output model reflecting emissions embodied in both domestically produced and imported goods and services we calculate the per capita carbon footprint the results from the analysis suggest that the per capita carbon footprint is directly proportional to expenditure with an estimated elasticity close to unity implying no decoupling the finding is partly driven by a near zero emission power sector which leads to comparatively low emissions embodied in domestically produced goods and services

energy requirements of households in brazil abstract in this study we determine the total direct plus indirect energy requirements of a given set of brazilian households we use a generalized input output model in order to calculate the energy embodied in goods and services purchased by households of different income level in 11 capital cities of brazil our results show that on average the total energy intensity of household expenditure increases with income level although there is a considerable spread in energy intensities within income classes as well as disparities between regions of the country the total yearly average energy requirement per household in brazil in 1995 96 was 173 6 gj 61 of which was indirect with 32 8 gj for the lower income level 66 of which was indirect and 602 2 gj for the higher income level 62 of which was indirect of this total average energy requirement 76 was required for only three consumption categories utilities 31 mobility 28 and shelter 17 this analysis calls for the attention that has to be given not only to the direct energy consumption as motor fuels and electricity for example but also to the consumption categories that encompass an important part of the indirect energy requirement of households in capital cities in brazil

poverty and distributional effects of carbon pricing in low and middle income countries a global comparative analysis abstract even though concerns about adverse distributional implications for the poor are one of the most important political challenges for carbon pricing the existing literature reveals ambiguous results for this reason we assess the expected incidence of moderate carbon price increases for different income groups in 87 mostly low and middle income countries building on a consistent dataset and method we find that for countries with per capita incomes of below usd 15 000 per year at ppp adjusted 2011 usd carbon pricing has on average progressive distributional effects we also develop a novel decomposition technique to show that distributional outcomes are primarily determined by differences among income groups in consumption patterns of energy rather than of food goods or services we argue that an inverse u shape relationship between energy expenditure shares and income explains why carbon pricing tends to be regressive in countries with relatively higher income since these countries are likely to have more financial resources and institutional capacities to deal with distributional issues our findings suggest that mitigating climate change raising domestic revenue and reducing economic inequality are not mutually exclusive even in low and middle income countries

qualitative and mixed methods research in economics surprising growth promising future qualitative research in economics has traditionally been unimportant compared to quantitative work yet there has been a small explosion in use of quantitative approaches in the past 10 15 years including mixed methods projects which use qualitative and quantitative methods in combination this paper surveys the growing use of qualitative methods in economics and closely related fields aiming to provide economists with a useful roadmap through major sets of qualitative methods and how and why they are used we review the growing body of economic research using qualitative approaches emphasizing the gains from using qualitative or mixed methods over traditional closed ended approaches it is argued that although qualitative methods are often portrayed as less reliable less accurate less powerful and or less credible than quantitative methods in fact the two sets of methods have their own strengths and how much can be learned from one type of method or the other depends on specific issues that arise in studying the topic of interest the central message of the paper is that well done qualitative work can provide scientifically valuable and intellectually helpful ways of adding to the stock of economic knowledge especially when applied to research questions for which they are well suited

financial liberalization and economic growth a meta analysis this study provides a systematic analysis of the empirical literature on the relationship between financial liberalization and economic growth by conducting a meta analysis based on 441 t statistics reported in 60 empirical studies we focus on explaining the heterogeneity of results in our sample in terms of study data and method specific characteristics although our findings indicate that on average there is a positive effect of financial liberalization on growth the significance of this effect is only weak moreover we find that most of the variables that may help explain the heterogeneity of results are insignificant there are two exceptions first studies carried out based on data from the 1970s on average find a statistically less significant relationship between financial liberalization policies and growth i e they report lower t statistics as compared to studies using data from the 1980s second studies controlling for the level of development of the financial system report lower t statistics for the relationship between liberalization and growth

energy and carbon embodied in the international trade of brazil an input output approach abstract all goods and services produced in an economy are directly and or indirectly associated with energy use and according to the type of fuel utilized with co2 emissions as well international trade is an important factor in shaping the industrial structure of a country and consequently in affecting a country s energy use and co2 emissions this study applies input output techniques to the brazilian economy to evaluate the total impacts of international trade on its energy use and co2 emissions a commodity by industry io model in hybrid units energy commodities in physical units and non energy commodities in monetary units is applied to the brazilian economy in 1995 results show that total energy embodied in the exports of non energy goods of brazil equals 831 pj while total carbon embodied is 13 5 mtc these amounts are larger than the relevant amounts embodied in the imports of non energy goods respectively 679 pj and 9 9 mtc these figures are better understood by contrasting them with the total energy use and the corresponding total carbon emissions of the brazilian economy in 1995 estimated by this work 6781 pj and 99 4 mtc respectively this means that international inflows and outflows of energy embodied in non energy goods are in the order of 10 and 12 of the total energy use while inflows and outflows of carbon embodied in non energy goods are approximately 10 and 14 of the corresponding total carbon emissions of the brazilian economy in 1995 the general picture is that brazil is not only a net exporter of energy 153 pj and of carbon 3 6 mtc embodied in the non energy goods internationally traded by the country in 1995 but also that each dollar earned with exports embodied 40 more energy and 56 more carbon than each dollar spent on imports these findings suggest that brazilian policy makers should be concerned about the extra impacts international trade policy may have on energy use and carbon emissions of the country

data revisions and forecasting the relationship between two sets of gnp data the earliest and the first revisions is examined this comparison enables us to determine whether the early numbers are valuable to forecasters the analysis uses two methods the first is based on a technique which has been used to evaluate whether financial and economic forecasts are valuable to the users the second approach uses time series techniques we conclude that revisions to the 15 day estimates that occur when the 45 day numbers are released are successful and that the 15 day numbers are useful to forecasters

do crises induce reform a critical review of conception methodology and empirical evidence of the crisis hypothesis the notion that economic crises induce the adoption of reform ranks among the most widely accepted concepts in the political economics literature however the underlying mechanism of the so called crisis hypothesis has yet to be fully understood this paper provides a comprehensive survey of the relevant empirical evidence to date and scrutinizes the operationalization of the hypothesis key concepts crisis reform and the political mediation of reform during crises we argue that the social perception of both crises and the subsequent cost of reform requires consideration of how these concepts are operationalized as a product of the broader economic and institutional environment social perceptions largely determine the manner in which the political mediation of reform during crises works present day methodological approaches fail to adequately reflect social perceptions and consequently compromise the determination of what constitutes both crisis and the cost of reform in the context of the crisis hypothesis most notably the identification of crises by fixed thresholds constructed around macroeconomic variables impedes the interpretation of the hypothesis underlying mechanism a fuller treatment of social perception within the operationalization of the hypothesis key concepts can enhance our understanding of how economic crises influence political dynamics in bringing about reform

income inequality and carbon dioxide emissions the case of chinese urban households abstract this paper draws on chinese survey data to investigate variations in carbon dioxide emissions across households with different income levels rich households generate more emissions per capita than poor households via both their direct energy consumption and their higher expenditure on goods and services that use energy as an intermediate input an econometric analysis confirms a positive relationship between emissions and income and establishes a slightly increasing marginal propensity to emit mpe over the relevant income range the redistribution of income from rich to poor households is therefore shown to reduce aggregate household emissions suggesting that the twin pursuits of reducing inequality and emissions can be achieved in tandem

quantifying the global and distributional aspects of american household carbon footprint abstract analysis of household consumption and its environmental impact remains one of the most important topics in sustainability research nevertheless much past and recent work has focused on domestic national averages neglecting both the growing importance of international trade on household carbon footprint and the variation between households of different income levels and demographics using consumer expenditure surveys and multi country life cycle assessment techniques this paper analyzes the global and distributional aspects of american household carbon footprint we find that due to recently increased international trade 30 of total us household co 2 impact in 2004 occurred outside the us further households vary considerably in their co 2 responsibilities at least a factor of ten difference exists between low and high impact households with total household income and expenditure being the best predictors of both domestic and international portions of the total co 2 impact the global location of emissions which cannot be calculated using standard input output analysis and the variation of household impacts with income have important ramifications for polices designed to lower consumer impacts on climate change such as carbon taxes the effectiveness and fairness of such policies hinges on a proper understanding of how income distributions rebound effects and international trade affect them

on the durability of non durable goods abstract using both monthly and quarterly data this paper shows that the durability rates of non durable goods and services are significantly greater than zero and in line with the prediction of the theory the common practice of testing consumption and consumption related models with the national income and product account category of non durables and services under the assumption of zero durability may thus be inappropriate
