wheat from chaff meta analysis as quantitative literature review abstract this paper presents and develops a quantitative method of literature reviewing and evaluating empirical research meta regression analysis or mra economics is theory driven yet we must learn empirically if economics is to advance mra offers a more objective statistical method to summarize our empirical knowledge and to explain the wide study to study variation in economic research mra is used to assess the evidence for ricardian equivalence and its findings are contrasted to those of conventional narrative review furthermore mra establishes a platform from which to distinguish genuine empirical effect from the exploitable specification error that infests applied econometrics

policy watch infrastructure investment and economic growth in the late 1980s david aschauer 1989 triggered a long overdue dialogue among economists and political leaders when he published a study arguing that much of the decline in u s productivity that occurred in the 1970s was precipitated by declining rates of public capital investment my own work confirmed these results munnell 1990a spending advocates seized on these findings as support for increased public investment the enthusiasm among policymakers for the early aschauer results was matched if not surpassed by skepticism on the part of many economists critics of these studies charged that the methodology was flawed that the direction of causation between public investment and output growth is unclear and that even if the historical empirical relationships were estimated correctly they provide no clear indications for current policy who s right what do we know and not know about the link between public infrastructure and productivity and what are the implications of these results for policy

conceptualising energy use and energy poverty using a capabilities framework in this article we conceptualise energy use from a capabilities perspective informed by the work of amartya sen martha nussbaum and others following them building on this we suggest a corresponding definition of energy poverty as understood in the capabilities space we argue that such an understanding provides a theoretically coherent means of comprehending the relationship between energy and wellbeing and thus conceptualising energy deprivation that makes sense across settings including both the global north and south a coherence which has previously been lacking at the same time it has the flexibility to be deployed in a way that is sensitive to local contexts understanding energy use in the capabilities space also provides a means for identifying multiple sites of intervention including some areas that are currently largely overlooked we argue that this is advantageous for attempts to address energy poverty in the context of climate change and imperatives for the containment of aggregate energy consumption

cambodia s energy poverty and its effects on social wellbeing empirical evidence and policy implications abstract this study aims to quantify the incidence of energy poverty in cambodia and its potential impact on the social wellbeing of the people of cambodia the notion of energy poverty of a household is not well understood in the context of literature as it may refer to either energy poor or economically poor condition of the household this study defines energy poverty in terms of lack of accessibility and or affordability of energy which may cause the deprivation of a household and affect its wellbeing the study uses the latest cambodia socio economic survey data 2015 cses 2015 to investigate the impacts of energy poverty on the health education and earning opportunities of the households the findings of the study suggest that energy poverty of a household is strongly associated with the type of fuel used and low consumption of unaffordable clean energy by the household the resulting impacts of energy poverty on the wellbeing of households are enormous energy poor households have a higher probability of its members suffering from respiratory problems spending more on medical care having a higher dropout rate from schools and lower earning opportunities than the households without energy poverty based on its findings the study suggests an urgent need of policy measures focusing on provision of clean and affordable energy to poor households to reduce eliminate energy poverty in cambodia

infrastructure and development a critical appraisal of the macro level literature this survey reviews the existing macro level empirical literature on the link between infrastructure and development outcomes in a critical light after providing a general framework that casts the relevant terms of the controversy on the real effect of infrastructure on growth in the context of an aggregate production function it signals what are the relevant empirical questions to be addressed this guides the systematic review of a number of empirical studies and the discussion of the main econometric challenges to the identification of the effect of infrastructure on output and productivity finally building on related research in particular in contract theory and political economy the paper spells out several promising research avenues

what have we learned since hotelling s letter a meta analysis abstract this paper reports the results of a meta analysis of the estimates of the price elasticity of demand for recreation sites using the travel cost method by using econometric methods to summarize empirical literature meta analysis assists in identifying research conclusions despite the non experimental nature of most empirical research in economics in this application the results suggest that modeling decisions based on theory as well as those relying on fitting criteria were important influences to the estimated price elasticities across studies

the use and abuse of meta analysis in environmental and natural resource economics an assessment motivated by the 2006 report of a work group appointed by the environmental protection agency epa this paper examines the present state of meta analysis in environmental economics and offers recommendations for its future use to this end we summarize and assess 140 meta analyses from 125 published and unpublished studies covering 17 topical categories in environmental and resource economics first we provide several generic meta analysis models as reference points and discuss major estimation issues five econometric issues are identified as part of a complete analysis 1 sample selection criteria 2 basic data summary 3 primary data heterogeneity 4 heteroskedasticity and 5 non independence of multiple observations from primary studies second a tabular summary is presented for the 140 meta analyses with respect to estimation methods third a narrative summary is presented for 19 meta analyses including the three value of statistical life studies examined by the epa work group and one analysis from each of 16 other categories fourth we offer a set of best practice guidelines for future meta analyses in this and other areas of economics last the paper comments on the use of meta analytic methods for benefit transfers of environmental values

taxes inflation and the durability of capital the choice of capital durability is affected by the rate of inflation because nominal depreciation deductions are based on historical cost rather than replacement cost this paper analyzes a model with competitive firms and demonstrates that an increase in the rate of inflation will lead to an increase in the durability of capital if the ratio of the nominal discount rate to the rate of depreciation exceeds a critical value however if this ratio is less than the crucial value this effect is reversed the effect of costs of adjustments on the crucial value is analyzed

managing the quality of a resource with stock and flow controls abstract we consider a class of problems which we call sfq problems in which both stocks and flows can be controlled to promote the quality of a valued resource such as environmental quality or public infrastructure under the optimal policy periodic restoration of the stock of quality complements positive but variable abatement of the flow of damages when deterioration is more rapid or highly variable or when abatement is more expensive relative to restoration the optimal policy relies relatively more on restoration when deterioration is due to private firms or individuals a flow tax equal to the present value of marginal damages provides efficient incentives for abatement this tax rises at first as quality worsens but eventually falls as restoration nears the revenues raised by such a tax approximates the cost of restoration with the two quantities converging as the variance of flows goes to zero we discuss the implications of the sfq model for a range of real world problems in the environmental arena and for the management of public infrastructure but the lessons are general and we briefly discuss how they apply to private stocks of physical and human capital

assessing the determinants and drivers of multidimensional energy poverty in ghana abstract improving household access and use of clean energy has been central to global development efforts in recent years the negative effects of energy poverty on health climate livelihoods and economy has led to increased investments towards achieving universal access to clean energy however significant deprivations in clean energy remains especially in developing countries energy poverty may involve simultaneous deprivations on availability and affordability of clean energy using repeated cross sectional data this paper assesses the extent and determinants of multidimensional energy poverty in ghana between 2008 and 2014 the paper finds that though the level of multidimensional energy poverty reduced in ghana between 2008 and 2014 the incidence and intensity of multidimensional energy poverty remains high further we find substantial subgroup differences in multidimensional energy poverty the results reveal significant relationships between household characteristics and the multidimensional energy poverty status of households the reductions in multidimensional energy poverty were driven by the coefficient effects attributable to structural and policy changes over the period to facilitate universal access to clean energy and reduce the degree of multidimensional energy poverty there is the need to intensify the lpg promotion campaign and adopt strategies that target left behind and underserved groups

on measuring energy poverty in indian households summary the relationship between energy and poverty is obvious and goes both ways recognizing this this paper provides a short overview of different approaches to measuring energy poverty it then presents a novel two dimensional measure of energy poverty and energy distribution that combines the elements of access to different energy types and quantity of energy consumed an assessment of the extent of energy poverty and changes in energy distribution pattern are analyzed by applying this measure to indian household survey data for 1983 2000 the analysis shows a significant reduction in the level of energy poverty and a rapidly developing subcontinent the new measure is a good complement to conventional monetary measures and is general enough to be applied to other developing countries

state infrastructure and productive performance recent research on productivity growth has focused on public infrastructure and its impact on economic growth and productivity the authors construct a model of firms technology and behavior taking advantage of the analytical framework provided in the cost function based applied production theory literature and apply it to state level data for u s manufacturing they find that infrastructure investment provides a significant return to manufacturing firms and augments productivity growth the net benefits of infrastructure investment may or may not be positive depending upon the social costs of infrastructure investment and the relative growth rates of output and infrastructure copyright 1996 by american economic association

filling potholes macroeconomic effects of maintenance versus new investments in public infrastructure abstract the maintenance of existing public infrastructure has often been neglected in favor of building new infrastructure in developing countries this paper develops a dynamic general equilibrium model that analyzes the reasons and effects of such neglect first the optimal level of maintenance is shown to depend on the size of new investments as a share of existing public infrastructure and on the productivity of infrastructure second the model is parameterized and solved numerically for a sample of latin american countries quantitative results show that reallocating funds from new infrastructure to maintenance can have positive effects on these countries gdp

are the energy poor also income poor evidence from india abstract the energy poverty line is defined as the threshold point at which energy consumption begins to rise with increases in household income this approach is applied to cross sectional data from a comprehensive 2005 household survey representative of both urban and rural india the objective is to determine if the energy poor are also income poor and whether and how energy policies help reduce energy poverty independent of income the findings suggest that in rural areas some 57 of households are energy poor versus 22 that are income poor but in urban areas the energy poverty rate is 28 compared to 20 that are income poor that is energy policies are expected to play some roles in mitigating energy poverty we find that reducing energy poverty requires not only support for rural electrification but also more use of modern cooking fuels such as lpg while income growth matters a combination of energy related programs can play an independent and substantial role in reducing energy poverty

beyond publication bias abstract this review considers several meta regression and graphical methods that can differentiate genuine empirical effect from publication bias publication selection exists when editors reviewers or researchers have a preference for statistically significant results because all areas of empirical research are susceptible to publication selection any average or tally of significant insignificant studies is likely to be biased and potentially misleading meta regression analysis can see through the murk of random sampling error and selected misspecification bias to identify the underlying statistical structures that characterize genuine empirical effect meta significance testing and precision effect testing pet are offered as a means to identify empirical effect beyond publication bias and are applied to four areas of empirical economics research minimum wage effects union productivity effects price elasticities and tests of the natural rate hypothesis

comprehensive energy poverty index measuring energy poverty and identifying micro level solutions in south and southeast asia abstract the absence of adequate modern sources of energy impedes the presence of decent living conditions this very lack of modern sources of energy is energy poverty lack of availability accessibility and affordability are the main reasons behind this problem in the literature all three aspects were not covered together in this paper we have developed a composite index of energy poverty to measure the magnitude of energy poverty in the asean region and india where we capture all three elements the measure revealed the degree of problem in each country with cambodia being the most energy poor amongst the countries in the study and thailand being the least energy poor to dig deeper into the problem at the micro level and to deliberate the policy implications we developed detailed village level case studies and analysed region specific energy poverty we thus identify the key root causes and propose effective solutions to eradicate the prevailing problem in these regions

getting help from abroad the macroeconomics of foreign direct investment in infrastructure in low income countries infrastructure financing needs in most low income countries are substantial but funding for such needs is only partly covered by national governments and aid donors this paper introduces foreign direct investment fdi through public private partnerships as a source of infrastructure financing in low income countries a two sector open economy model is developed to assess the macroeconomic performance of fdi in infrastructure with efficient foreign investment an increase in revenue generating infrastructure investment boosts productivity and spurs private investment while stabilizing domestic prices a direct comparison between infrastructure financed by domestic versus foreign investment shows that foreign investment creates higher output growth and welfare gains and is preferable to domestically sourced investment irrespective of the underlying financing instrument the domestic economy is employing fdi in non revenue generating infrastructure is also analyzed and discussed

a meta analysis on the price elasticity of energy demand abstract price elasticities of energy demand have become increasingly relevant in estimating the socio economic and environmental effects of energy policies or other events that influence the price of energy goods since the 1970s a large number of academic papers have provided both short and long term price elasticity estimates for different countries using several models data and estimation techniques yet the literature offers a rather wide range of estimates for the price elasticities of demand for energy this paper quantitatively summarizes the recent but sizeable empirical evidence to facilitate a sounder economic assessment of in some cases policy related energy price changes it uses meta analysis to identify the main factors affecting short and long term elasticity results for energy in general as well as for specific products i e electricity natural gas gasoline diesel and heating oil

energy poverty in rural bangladesh energy poverty is a well established concept among energy and development specialists international development organizations frequently cite energy poverty alleviation as a necessary condition to reduce income poverty several approaches used to measure energy poverty over the past 20 years have defined the energy poverty line as the minimum quantity of physical energy needed to perform such basic tasks as cooking and lighting this paper uses a demand based approach to define the energy poverty line as the threshold point at which energy consumption begins to rise with increases in household income at or below this threshold point households consume a bare minimum level of energy and should be considered energy poor this approach was applied using cross sectional data from a comprehensive 2004 household survey representative of rural bangladesh the findings suggest that some 58 percent of rural households in bangladesh are energy poor versus 45 percent that are income poor the findings also suggest that policies to support rural electrification and greater use of improved biomass stoves might play a significant role in reducing energy poverty

public investment in infrastructure in a simple growth model abstract in this paper we examine the implications for capital accumulation when infrastructure enters as an external input into private production functions in our model infrastructure is nonexclusive but may exhibit varying degrees of nonrivalry revenues from uniform taxes on capital and labor income are used to finance public investment in infrastructure we show that the optimal tax rate is independent of the degree of nonrivalry when production exhibits constant returns to augmentable factors the equilibrium displays constant growth for most parameters the growth rate depends on the population size under decreasing returns the optimal trajectory exhibits monotonic convergence to a steady state level

intertemporal output and employment effects of public infrastructure capital evidence from 12 oecd economies this paper utilises an intertemporal optimisation framework to study the effects of public infrastructure capital on output supply and input demands in 12 oecd countries we find that in all 12 countries i public capital has positive long run effects on both output supply and input demands ii its mean short run rates of return are fairly low while the corresponding long run rates are much higher but declining over time these findings underscore important under investment gaps in infrastructure during the 1970s and 1980s these gaps however narrowed down significantly in a few cases completely by the early 1990s

meta regression analysis a quantitative method of literature surveys abstract pedagogically literature reviews are instrumental they summarize the large literature written on a particular topic give coherence to the complex often disparate views expressed about an issue and serve as a springboard for new ideas however literature surveys rarely establish anything approximating unanimous consensus ironically this is just as true for the empirical economic literature to harmonize this dissonance we offer a quantitative methodology for reviewing the empirical economic literature meta regression analysis mra is the regression analysis of regression analyses mra tends to objectify the review process it studies the processes that produce empirical economic results as though they were any other social scientific phenomenon mra provides a framework for replication and offers a sensitivity analysis for model specification in this brief essay we propose a new method of reviewing economic literature mra and discuss its potential

introducing a new currency government policy and prices abstract the aim of this article is to study the introduction of a new fiat currency within a dual currency divisible goods search model the government using price control or legal tender laws can affect the equilibrium price levels of two domestic currencies with the goal of driving the old currency out of circulation and replacing it with a new one it is shown that some equilibrium solutions that exist in a laissez faire environment disappear with government monitoring additionally when the old currency is made illegal its equilibrium value is affected differently by public measures such as conversion tax and redistribution policies finally if the enforcement power of legal tender laws is strong enough the old currency cannot be more valuable than the new one and the probability that it changes hands in trade when introducing lotteries cannot be smaller than one

assessing the extent and intensity of energy poverty using multidimensional energy poverty index empirical evidence from households in india abstract in this paper we have made a comprehensive assessment of the extent and various socio economic implications of energy poverty in india amartya sens s capability approach to development underpins the analysis of household level data taken from the india human development survey ii ihds ii 2011 12 using the multidimensional energy poverty index mepi the overall results show that energy poverty is widespread in india and the existence of energy poverty also coincides with the other forms of deprivations such as income poverty and social backwardness for example dalits lower caste and adivasis tribal are found to be extremely energy poor compared to the other social groups in india the results also reveal that it is the responsibility of women to manage the domestic chores such as collection of firewood and making of dung cake in traditional indian households inefficient use of such biomass fuels is found to cause health hazards

on energy consumption and gdp studies a meta analysis of the last two decades abstract the relationship between energy consumption and gdp growth has been intensely examined in multiple frameworks set by various methods and countries this paper is a meta analysis of 51 studies published in the last two decades with worldwide data since 1949 on the relationship between energy consumption and gdp growth the aim is to systemize some of the factors that cause the variation of results in these studies our results yield evidence that the long run elasticity of gdp growth with respect to energy consumption is not independent of the method employed for cointegration the data type and the inclusion of variables such as the price level or capital in the cointegration equation also 1 increase in capital increases the elasticity of gdp with respect to energy consumption by 0 85

roads to prosperity assessing the link between public capital and productivity does the positive correlation between infrastructure and productivity reflect causation if so in which direction the author finds that when growth in roads the largest component of infrastructure changes productivity growth changes disproportionately in u s industries with more vehicles that vehicle intensive industries benefit more from road building suggests that roads are productive at the margin however road investments do not appear unusually productive intuitively the interstate system was highly productive but a second one would not be road building thus explains much of the productivity slowdown through a one time unrepeatable productivity boost in the 1950s and 1960s

rural electrification and energy poverty empirical evidences from brazil the aim of this article is to evaluate the impact of rural electrification on the reduction of energy poverty in brazil through the analysis of 23 000 rural domiciles or rural properties between the years 2000 and 2004 the results indicate a fast change in the profile of energy consumption and a reduction of energy poverty this new approach works as a complement among other variables to analyze and quantify the real economic social and energy impacts in rural electrification programs generally applied in developing countries

energy poor or fuel poor what are the differences abstract energy poverty and fuel poverty are descriptors of problems of households energy consumption they are both distinct problems and have been addressed by many researchers organizations and governments cross use of the terms of energy poverty and fuel poverty in published papers is common as an accurate descriptor is the presupposition of research and policy development especially for those who just started to pay attention to this issue this paper compares the definitions research priorities status quo and problems of these two concepts and summarizes the relationship between them the paper suggests that only when the research targets are households who are living in a cold climate and have difficulty in getting access to electricity or modern cooking facilities and in supplying indoor heating with appropriate cost the concepts of energy poverty and fuel poverty have the chance to be broadened and mutually integrated

infrastructure provision and macroeconomic performance this paper studies the differences between private and government provision of infrastructure capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for fiscal policy a subsidy to private providers of infrastructure is preferable to direct government provision irrespective of how the subsidy or expenditure is financed the case for private provision is much stronger in economies characterized by high levels of congestion the choice between private and government provision also has a crucial effect on the design of optimal fiscal policy 2011 elsevier b v all rights reserved

on the macroeconomic implications of maintenance in public capital abstract an infrastructure led growth model is constructed where the durability of public capital is endogenous and varies according to its usage and the level of maintenance expenditure policy changes in total expenditures and the maintenance share are shown to be important for the steady state and the dynamic behavior of the economy the optimal growth maximizing taxation burden which goes to both new investment and maintenance expenditure is in contrast to standard results from other growth models larger than the elasticity of infrastructure in the production function the optimal shares of maintenance expenditure and investment in new capital that ensure maximum utilization of public resources are calculated

what moves and works broadening the consideration of energy poverty greater detail on the specific technological and planning challenges facing energy deprived developing economies is required to improve energy policy making and development assistance practice the current literature tends to highlight electricity services and to a lesser extent clean cooking this article calls for a closer look at mobility and mechanical power as essential energy services in addition to a refinement of the specific institutional arrangements needed to reduce energy poverty and deprivation this article augments and refines arguments made by morgan bazilian and his colleagues in their viewpoint more heat and light

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

reprint to infrastructure provision and macroeconomic performance abstract this paper studies the differences between private and government provision of infrastructure capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for fiscal policy a subsidy to private providers of infrastructure is preferable to direct government provision irrespective of how the subsidy or expenditure is financed the case for private provision is much stronger in economies characterized by high levels of congestion the choice between private and government provision also has a crucial effect on the design of optimal fiscal policy

infrastructure alternative government finance and stochastic endogenous growth abstract this paper constructs a stochastic version of an endogenously growing economy with a public good that raises the productivity of private capital we explore how growth and welfare are influenced by changes in the mean and variance of productive public spending under two alternative financing methods mixed money bond financing and wealth tax financing in addition to evaluate the differences between money financing and bond financing we consider mixed money bond financing under which a larger ratio of bonds to money is utilized to finance a given increase in public spending

a multidimensional measure of energy poverty in china and its impacts on health an empirical study based on the china family panel studies abstract inability or insufficient access to modern forms of energy is an important issue in development which makes the notion of energy poverty a widely discussed topic a consensus has been reached that energy poverty has serious health education and other socio economic impacts for people in a country however measurements of energy poverty have generally been absent or inaccurate especially for developing countries at the micro level this paper begins with the multidimensional nature of energy poverty and uses household level survey data in china to construct a quantitative measure of energy poverty covering both affordability of and accessibility to a broad range of forms of energy it then builds an econometric model to address empirically how much energy poverty affects health a statistically significant and robust negative impact on health from energy poverty is confirmed our results have important policy relevance in terms of understanding the current status quo of energy poverty in china and its consequences the concept can also be expanded to investigate similar issues in other developing countries

public investment optimal provision of hicksian public inputs a considerable portion of government spending is devoted to commodities that are not public goods but that directly affect production possibilities examples include public infrastructure like roads and dams educational facilities and research projects in basic science and some forms of information such commodities are public inputs in a small open economy context the focus of this paper is on those that are hicksian in nature an interesting decomposition of the beneficial impact of a hicksian public input is developed then first best and second best optimality conditions for public inputs that are comparable to those for collective consumption goods are derived

productiveness and welfare implications of public infrastructure a dynamic two sector general equilibrium analysis abstract this paper develops a dynamic general equilibrium model that provides an internally consistent micro foundations framework where various effects of infrastructure policy changes can be studied devoting additional resources to infrastructure investment can payoff in terms of sizable increases in gdp and private investment in addition to this the model also makes predictions concerning changes in the welfare of agents resulting from additional infrastructure investment specific policy recommendations that attain highest welfare gains are computed the recommendation is that on average an additional 4 of gdp per year should be devoted to public investment in the latin american countries in the sample

public capital maintenance and congestion long run growth and fiscal policies abstract in this paper we study an endogenous growth model in which public maintenance expenditures affect the depreciation rate of public capital and the latter is subject to congestion we find that economies with low congestion in public infrastructure will require a threshold level of public capital maintenance for ongoing growth we also examine the fiscal implications of public capital maintenance policies and we find that the composition of public capital expenditures under congestion is a crucial determinant of optimal and growth maximizing fiscal policies the government can affect the return of public capital by re allocating public expenditures between new public investment and maintenance and hence avoid excessive taxation that is required under increasing congestion

the transition from barter to fiat money how did it become possible to exchange apparently valueless pieces of paper for goods this paper provides an equilibrium account of the transition between barter and fiat money regimes the explanation relies on the intervention of a self interested government that must be able to promise credibly to limit the issue of money to achieve credibility the government must offset the benefits of seigniorage by internalizing some of the macroeconomic externalities generated by the issue of fiat money the government s patience and the extent of its involvement in the economy are key determinants of whether the transition can be accomplished copyright 1995 by american economic association

the composition of public expenditure and economic growth abstract noting that the literature has focused on the link between the level of public expenditure and growth we derive conditions under which a change in the composition of expenditure leads to a higher steady state growth rate of the economy the conditions depend not just on the physical productivity of the different components of public expenditure but also on the initial shares using data from 43 developing countries over 20 years we show that an increase in the share of current expenditure has positive and statistically significant growth effects by contrast the relationship between the capital component of public expenditure and per capita growth is negative thus seemingly productive expenditures when used in excess could become unproductive these results imply that developing country governments have been misallocating public expenditures in favor of capital expenditures at the expense of current expenditures

meta analysis of empirical evidence on energy poverty the case of developing economies abstract energy poverty has evolved as an important issue of research from academic and policy perspectives during the last two decades the energy poverty estimates exhibit widespread variations across regions methodologies and datasets making the task of energy and development policies challenging the variations in energy poverty estimates necessitate a systematic and rigorous analysis of these empirical studies to obtain a true measure of energy poverty the present study conducts a meta analysis of 30 studies and 103 estimates of energy poverty on average 71 1 percent of the population in the overall sample studies has been identified as energy poor high i square statistic values suggest heterogeneity bias in the sample studies therefore analysis at the subgroup level has been conducted meta regression analysis of overall sample and subgroups has identified type of methodology citations impact factor of the journal regional dummies average key crude oil price and gross domestic product as significant factors that explain heterogeneity in the energy poverty effect sizes we recommend inclusion of local and regional factors in assessment of energy poverty for developing a uniform methodology to assess energy poverty across developing economies

measuring energy poverty focusing on what matters abstract the provision of modern energy services is recognised as a critical foundation for sustainable development and is central to the everyday lives of people effective policies to dramatically expand modern energy access need to be grounded in a robust information base metrics that can be used for comparative purposes and to track progress towards targets therefore represent an essential support tool this paper reviews the relevant literature and discusses the adequacy and applicability of existing instruments to measure energy poverty drawing on those insights it proposes a new composite index to measure energy poverty both the associated methodology and initial results for several african countries are discussed whereas most existing indicators and composite indices focus on assessing the access to energy or the degree of development related to energy our new index the multidimensional energy poverty index mepi focuses on the deprivation of access to modern energy services it captures both the incidence and intensity of energy poverty and provides a new tool to support policy making

new public investment and or public capital maintenance for growth the canadian experience i introduction in search of the determinants of long run growth a strand of the relevant literature has focused on the growth impact of public productive expenditures the theoretical work of barro 1990 barro and sala i martin 1992 and others and the empirical evidence by several studies surveyed by gemmel and kneller 2001 have stressed the role of government productive activities as key determinants of long run growth the impact of public expenditures typically takes the form of positive production externalities that enhance private sector productivity via private firms production function either as a flow government productive services or as a stock public or infrastructural capital 1 the adoption of this framework embeds two central assumptions on the nature of public capital expenditures first all expenditures related to the public capital accumulation process of the economy are oriented to the formation of new public capital through investment second public capital deterioration is considered as an exogenously given technical relationship hence this approach neglects a crucial choice concerning the implementation of public investment decisions namely the choice between investing in new public capital and extending the durability of the existing public capital stock the cost paid for the latter option is usually called maintenance expenditures for public capital and strictly speaking should be classified under the budgetary term public investment because it fulfills two basic criteria 1 it is financed by taxation or government borrowing and 2 it does not result in public consumption expenditures but instead increases the public capital stock available in the economy 2 despite the intuitive consensus on the crucial weight of maintenance expenditures in public capital and the trade off with expenditures in new public investment there have been few systematic attempts to investigate their macroeconomic impact an attempt to analyze this trade off has been recently made by rioja 2003 who sets up a growth model where domestic tax revenues finance maintenance expenditures for public capital whereas public infrastructure is financed solely by foreign donors the author shows that the optimal maintenance level as a share of output depends on various parameters and presents calibration results from latin american countries that confirm the importance of maintenance for the pattern of growth in these countries along this line kalaitzidakis and kalyvitis 2004 extend rioja s model by concentrating on the implications of maintenance expenditures for public capital formation on growth in their model both types of expenditures are financed by a tax on output by altering their allocation the government can use the share of maintenance as a policy instrument and raise the shadow value of private capital thus leading the economy to a higher growth rate an appealing implication is that the growth maximizing share of taxation is higher than the elasticity of public capital in the production function which reverses a standard argument put forward by among others barro 1990 glomm and ravikumar 1994 devarajan et al 1998 as the additional positive effect of maintenance expenditure on the accumulation of public capital raises the benefits of taxation compared to the standard models although theoretically sound these relationships do not translate easily into operational guidelines for policy makers on the growth effects of maintenance and new public capital expenditures 3 ideally one would like to test these implications in the context of a wide cross country data set consisting of data on each of the two components of public expenditures unfortunately published data on maintenance are very scarce involving only a handful of private activities due to inherent problems in the measurement of this type of expenditures mcgrattan and schmitz 1999 describe the difficulties in constructing aggregate measures of maintenance and repair the authors point out that for instance in the united states maintenance activities are largely carried out outside the market and thus recorded transactions are usually incomplete
