do conditional cash transfers for schooling generate lasting benefits a five year followup of progresa oportunidades conditional cash transfer cct programs link public transfers to human capital investment in hopes of alleviating current poverty and reducing its intergenerational transmission however little is known about their long term impacts this paper evaluates longer run impacts on schooling and work of the best known cct program mexico s progresa oportunidades using experimental and nonexperimental estimators based on groups with different program exposure the results show positive impacts on schooling reductions in work for younger youth consistent with postponing labor force entry increases in work for older girls and shifts from agricultural to nonagricultural employment the evidence suggests schooling effects are robust with time

can falling supply explain the rising return to college for younger men a cohort based analysis although the college high school wage gap for younger u s men has doubled over the past 30 years the gap for older men has remained nearly constant in the united kingdom and canada the college high school wage gap also increased for younger relative to older men using a model with imperfect substitution between similarly educated workers in different age groups we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups the driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries

occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

the long term effects of forcible assimilation policy the case of indian boarding schools for decades in north america and australia indigenous children were forcibly removed from their homes and placed in boarding schools these schools had the stated goal of cultural assimilation and are perceived as educational failures i offer the first causal evidence on the long run effects of these schools i identify these effects using the interaction of changes in canadian national policy and regional variation in the power of the catholic church i find that the average boarding school had substantial effects on both cultural and economic assimilation however i find suggestive evidence this is not true for highly abusive schools

forecasting residential electricity consumption in greece using monthly and quarterly data abstract this paper studies electricity consumption household use only in greece we explore the dynamic relationships among several potentially relevant time series variables and develop appropriate models for forecasting it is apparent that personal disposable income temperature and the price of electricity used by the households play an important role in the demand for electricity in this study we use both monthly and quarterly data and find that the performance of quarterly models may not be as good as that of the monthly ones for transfer function model identification we use the linear transfer function ltf method which is more efficient and easier to use than the traditional cross correlation ccf method

residential energy demand in oecd countries and the role of irreversible efficiency improvements abstract after undergoing substantial changes during a period of high energy prices household energy demand did not rebound in times of declining energy prices as might have been expected hence other factors such as irreversible improvements in technical efficiency must be understood in order to describe both past and future household energy demand in this paper we consider irreversible efficiency improvements as a major reason for the moderate growth in energy demand after the plummeting of the oil price in 1985 we test different econometric models to take into account efficiency indicators the major conclusions of our investigation are i price elasticities are different for rising and falling prices for the latter they are close to zero implying a low rebound effect in the residential sector ii technical efficiency is an important parameter for describing and forecasting energy demand and iii income elasticities turn out to be higher once we incorporate indicators of technological efficiency in the process of estimating energy demand

economic growth comparative advantage and gender differences in schooling outcomes evidence from the birthweight differences of chinese twins abstract data from two surveys of twins in china are used to contribute to an improved understanding of the role of economic development in affecting gender differences in the trends in levels of and returns to schooling observed in china and in many developing countries in recent decades in particular we explore the hypothesis that these phenomena reflect differences in comparative advantage with respect to skill and brawn between men and women in the context of changes in incomes returns to skill and or nutritional improvements that are the result of economic development and growth

the terms of trade between oil importers abstract an intertemporal model of opec and two large country oil importers is used to show that asymmetries between importers cause oil price changes to alter the terms of trade between them in systematic ways for example differences in oil dependence marginal propensities to save international debt positions factor substitutability trade in capital goods and wage setting behavior can all influence the final goods terms of trade between oil importers in predictable ways when oil prices change

short and long run elasticities in energy demand a cointegration approach abstract short and long run energy demand elasticities are estimated on danish annual data for 1948 1990 energy consumption the real price of energy and real gdp appear to be non stationary variables cointegration and error correction methods are therefore applied all estimated parameters have the expected signs and magnitudes and no evidence is found of a structural break in energy demand caused by the increases in real energy prices since 1973 74

carbon tax scenarios and their effects on the irish energy sector abstract in this paper we use annual time series data from 1960 to 2008 to estimate the long run price and income elasticities underlying energy demand in ireland the irish economy is divided into five sectors residential industrial commercial agricultural and transport and separate energy demand equations are estimated for all sectors energy demand is broken down by fuel type and price and income elasticities are estimated for the primary fuels in the irish fuel mix using the estimated price and income elasticities we forecast irish sectoral energy demand out to 2025 the share of electricity in the irish fuel mix is predicted to grow over time as the share of carbon intensive fuels such as coal oil and peat falls the share of electricity in total energy demand grows most in the industrial and commercial sectors while oil remains an important fuel in the residential and transport sectors having estimated the baseline forecasts two different carbon tax scenarios are imposed and the impact of these scenarios on energy demand carbon dioxide emissions and government revenue is assessed if it is assumed that the level of the carbon tax will track the futures price of carbon under the eu ets the carbon tax will rise from 21 50 per tonne co2 in 2012 the first year forecasted to 41 in 2025 results show that under this scenario total emissions would be reduced by approximately 861 000 tonnes of co2 in 2025 relative to a zero carbon tax scenario and that such a tax would generate 1 1 billion in revenue in the same year we also examine a high tax scenario under which emissions reductions and revenue generated will be greater finally in order to assess the macroeconomic effects of a carbon tax the carbon tax scenarios were run in hermes the esri s medium term macroeconomic model the results from hermes show that a carbon tax of 41 per tonne co2 would lead to a 0 21 contraction in gdp and a 0 08 reduction in employment a higher carbon tax would lead to greater contractions in output

some economics of global warming the greenhouse effect itself is simple enough to understand and is not in any real dispute what is in dispute is its magnitude over the coming century its translation into changes in climates around the globe and the impacts of those climate changes on human welfare and the natural environment these are beyond the professional understanding of any single person the sciences involved are too numerous and diverse demography economics biology and the technology sciences are needed to project emissions atmospheric chemistry oceanography biology and meteorology are needed to translate emissions into climates biology agronomy health sciences economics sociology and glaciology are needed to identify and assess impacts on human societies and natural ecosystems and those are not all there are expert judgments on large pieces of the subject but no single person clothed in this panoply of disciplines has shown up or is likely to this article makes an attempt to forecast the economic and social consequences of global warming due to anthropogenic greenhouse gases and attempting to prevent it

the dual political economy of taxes and tradable permits abstract the widely accepted difference in the political economy of taxes and tradable permits results from overly simple models a more general model shows that the distributional impacts driving the political economy of grandfathered permits can be similar for both policies

the chinese box the opaque economic borders of the chinese state although the state in china is no longer all encompassing as it had been during the pre 1979 centrally planned period it still reaches into numerous areas of the economy notably through its continuing ownership of state owned enterprises as a result china poses a paradox in that it has incomplete property rights and rule of law which are thought to be essential for growth there are though numerous inefficiencies associated with such a gradual transition which may have maintained a stable growth rate in the past but could hamper future economic development as a key example state owned firms continue to benefit from financial repression in which they received preferable allocations of credit thus china s high savings rate fuels investment which has driven growth but is increasingly inefficient as credit is funnelled to the less productive soes this inefficiency points to the need for legal and institutional reforms which may conflict with the still broad but opaque borders of the chinese state copyright 2011 oxford university press

does schooling cause growth a number of economists find that growth and schooling are highly correlated across countries a model is examined in which the ability to build on the human capital of one s elders plays an important role in linking growth to schooling the model is calibrated to quantify the strength of the effect of schooling on growth by using evidence from the labor literature on mincerian returns to education the upshot is that the impact of schooling on growth explains less than one third of the empirical cross country relationship the ability of reverse causality to explain this empirical relationship is also investigated

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

effects of carbon taxes in an economy with prior tax distortions an intertemporal general equilibrium analysis abstract this paper analyzes the costs of carbon taxes in a model that recognizes interactions between this tax and pre existing taxes first we examine the extent to which costs of a u s carbon tax are reduced when its revenues finance cuts in income taxes such use of revenues significantly reduces but does not eliminate the overall policy costs the positive overall costs reflect the carbon tax s focus on intermediate inputs and its relatively narrow base in comparison with income taxes we also examine the sensitivity of the carbon tax s costs to the level of pre existing taxes for any given use of revenues welfare costs rise significantly with pre existing tax rates indicating that models disregarding pre existing taxes may substantially understate the costs of new environmental tax initiatives

modeling industrial energy demand in greece using cointegration techniques abstract this paper attempts to shed light on the determinants of industrial energy demand in greece for this purpose we used cointegration analysis in order to capture short run and long run elasticities for oil and electricity industrial demand respectively the sample spans the period 1970 2004 from the empirical analysis and the johansen s maximum likelihood procedure we found cointegration for oil and electricity demand the results suggest that industrial energy demand is inelastic both in the short and the long run while electricity and oil are substitutes also oil and electricity prices are weakly exogenous both in the short and the long run

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

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

a carbon tax to reduce co2 emissions in europe abstract this paper examines the effects of introducing a tax on carbon dioxide emissions produced by combustion processes in oecd european countries a sectoral model of energy consumption is constructed to examine energy saving and inter fuel substitution effects induced by the introduction of various carbon taxes the simulation period is 1989 1994 our results provide a mild support to the environmental role of a carbon tax energy saving or inter fuel substitution processes that result from the introduction of environmental taxation stabilize emissions at the 1988 level only in the electricity generation sector and only if high tax rates are assumed 100 ton c by contrast total emissions all sectors and all fuels keep growing and the implementation of a tax of 100 ton c can only reduce the emission growth rate these results would recommend the introduction of several coordinated environmental instruments the last part of the paper compares results concerning oecd europe with those obtained when examining a single country italy the comparison does not seem to be in favour of a uniform carbon tax it rather indicates that environmental policy should be designed taking into account the specific economic situation and technological choices of each single country country specific coordinated environmental policies are to be recommended where international coordination ought to concern environmental targets rather than instruments

the effect of the german and british environmental taxation reforms a simple assessment abstract this article implements a simple econometric approach to assess the effect of the environmental tax reforms introduced in germany and the uk despite the very simple econometric approach adopted in this paper in the case of the energy demand our results do not differ markedly from those obtained from complicated multi sectoral econometric models in the case of the labour demand our results differ from the estimates obtained from econometric models where the employment level is not directly influenced by the energy price on the other hand our results are more similar to those obtained from models where the level of employment is directly influenced by the energy price confirming the findings of bosquet 2000 environmental tax reform does it work a survey of the empirical evidence ecological economics 34 19 32 and oecd 2004 environment and employment an assessment working party on national environmental policy oecd paris we conclude that environmental tax reforms can deliver substantial reductions in energy consumption while having small effects on the level of employment effect which can be positive depending on the size of the reduction in the labour costs and the value of cross price elasticities

competitiveness and exemptions from environmental taxes in europe a number of european countries have introduced a variety of environmental taxes a common characteristic of their implementation is the inclusion of exemptions and tax relief in particular for some sectors of manufacturing industry this paper analyses the pattern and motivation of exemptions as they have developed in western european countries making clear the difference between the nominal and effective tax rates once the exemptions have been taken into account the principal motivation for exemptions relates to concern about competitiveness while particular environmentally intensive sectors may have some grounds for concern even these might be able to achieve cost effective environmental improvements such that their competitive position is not over disadvantaged while for an economy structured like the uk s an environmental tax plus rebate scheme sometimes called an ecological tax reform would be likely to yield benefits in terms of competitiveness the exemptions usually run counter to the environmental economic logic of using environmental taxes to internalise social costs and give economic signals that are based on the full costs of production and they are likely to increase the costs of achieving a given level of emission reduction with little justification for them also on the grounds of competitiveness it would therefore be undesirable on both economic and environmental grounds for them to remain a feature of the implementation of environmental taxes in the future

toward a macroeconomics of the medium run these days macroeconomics has become more respectable than it used to be i can remember when many economists liked to say microeconomics is not problematic but i just don t understand macroeconomics there was a definite implication that something must be wrong with macroeconomics not with the observer of course macroeconomics cannot be exact it has to work by rough analogy and empirical compromise maybe a certain raffishness is inevitable most economists work on microeconomic problems with increasing use of new microeconomic data but now it is widely understood that macroeconomics is at the heart of economics it will not do to be snooty about it this centrality will continue for the best possible reason the need to understand current events especially unfavorable ones and to formulate policies even benign neglect is a policy to

energy taxes as a signaling device an empirical analysis of consumer preferences this paper presents an econometric study dealing with household demand in sweden the main objective is to empirically examine the differences in consumer reaction to the introduction of or the change in environmental taxes main focus is on environmental taxes as a signaling device the hypothesis is that the introduction of an environmental tax provides new information about the properties of the directly taxed goods this in turn may affect consumer preferences for these goods hence altering the consumption choice the result from the econometric analysis shows that all goods have negative own price elasticities and positive income elasticities concerning the signalling effect of environmental taxes the results are somewhat ambiguous the tax elasticity for energy goods used for heating seems to be significantly higher than the traditional price elasticity whereas the opposite seems to be the case for energy goods used for transportation

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

the enduring impact of the american dust bowl short and long run adjustments to environmental catastrophe the 1930 s american dust bowl was an environmental catastrophe that greatly eroded sections of the plains analyzing new data collected to identify low medium and high erosion counties the dust bowl is estimated to have immediately substantially and persistently reduced agricultural land values and revenues during the depression and through at least the 1950 s there was limited reallocation of farmland from activities that became relatively less productive agricultural adjustments such as reallocating land from crops to livestock recovered only 14 to 28 of the initial agricultural cost the economy adjusted predominately through migration rather than through capital inows and increased industry

inducing truthful revelation of generator reliability abstract liberalised electricity markets often include a capacity remuneration mechanism to allow generation firms recover their fixed costs various de rating factors and or penalties have been incorporated into such mechanisms in order to reward the unit based on the contribution they make to system security which in turn depends on the unit s reliability however this reliability is known to the firm but not to the regulator we adopt a mechanism design approach for capacity payments based on a declaration by the firm of their reliability the mechanism scales payments and penalties according to this declared reliability such that the firm s profit maximising strategy is to truthfully reveal its reliability a stochastic mixed complementarity problem mcp is used to model the interactions between the firms and we apply this methodology to a test system using irish electricity market data truth telling is induced increasing the efficiency of capacity payments while eliminating the requirement for the regulator to allocate resources to discovering reliability

economic growth and the demand for education is there a wealth effect abstract human capital investment in developing countries is thought to be significantly constrained by household resources this paper studies the relationship between household resources and the demand for education using recent household survey data from vietnam the data cover a period 1993 1998 of exceptional income growth in vietnam during which secondary school enrollment rose substantially using consumption expenditures to measure household wealth we find a positive and significant relationship between changes in wealth and changes in the demand for education this wealth effect persists even after controlling for locality specific factors such as changes in education returns and the supply and quality of schools and for the opportunity costs of schooling

a method for analyzing pollution control policies application to so2 emissions in china abstract market based pollution control mechanisms such as pollution levy and cap and trade have received increasing attention from both academics and practitioners a good understanding of the optimal pollution price under these mechanisms is a premise for regulators to make sound pollution control policies in this paper we propose a method for deriving the optimal pollution price for a given pollution target this method consists of two steps that integrate cost function estimation and market equilibrium analysis first historical data is used to estimate the pollution abatement cost functions of the polluters second market models are used to solve the equilibrium pollution price under each control mechanism for illustration we apply the method to investigate so 2 emission control policies in china using a dataset of so 2 emissions and abatement costs from three major industry sectors electricity gas and water supply manufacturing and mining our analysis shows that the optimal levy rate is significantly higher than the actual rate adopted by the chinese government for example the optimal levy rate should be 4 92 rmb kg while the actual rate is 1 26 rmb kg in 2010 as a result the actual emission structure is much less efficient the overall cost savings would be 49 7 for all three sectors during 2006 2010 if the optimal emission structure is achieved these findings have useful policy implications for the chinese government in addition the method may be applied to analyze control policies at different aggregate levels for example provincial economies or for other pollutants for example co 2 and chemical oxygen demand

energy consumption and economic growth a causality analysis for greece abstract this paper investigates the causal relationship between aggregated and disaggregated levels of energy consumption and economic growth for greece for the period 1960 2006 through the application of a later development in the methodology of time series proposed by toda and yamamoto 1995 at aggregated levels of energy consumption empirical findings suggest the presence of a uni directional causal relationship running from total energy consumption to real gdp at disaggregated levels empirical evidence suggests that there is a bi directional causal relationship between industrial and residential energy consumption to real gdp but this is not the case for the transport energy consumption with causal relationship being identified in neither direction the importance of these findings lies on their policy implications and their adoption on structural policies affecting energy consumption in greece suggesting that in order to address energy import dependence and environmental concerns without hindering economic growth emphasis should be put on the demand side and energy efficiency improvements

norwegian emissions of co 2 1987 1994 several countries have introduced taxes on fossil fuels with the aim of reducing atmospheric emissions partly because of local environmental goals so2 nox and partly to participate in a global effort to reduce emissions of greenhouse gases many macroeconomic studies based on both global and national models have been made of how emissions can be reduced with the help of taxes and the consequent reduction in gdp following the introduction of such taxes norway has had a co2 tax for five years thereby providing a unique opportunity to evaluate the effects of this tax on emissions the paper provides a counterfactual analysis of energy consumption and emissions if no co2 taxes had been introduced compared with the actual situation in which such taxes exist the effect of a co2 tax on oil consumption and thus co2 emissions is studied on the basis of partial economic models for various sectors of the norwegian economy the study indicates that the co2 tax has had an impact on co2 emissions in norway

the role of shocks and institutions in the rise of european unemployment the aggregate evidence two key facts about european unemployment must be explained the rise in unemployment since the 1960s and the heterogeneity of individual country experiences while adverse shocks can potentially explain much of the rise in unemployment there is insufficient heterogeneity in these shocks to explain cross country differences alternatively while explanations focusing on labour market institutions explain current heterogeneity well many of these institutions pre date the rise in unemployment based on a panel of institutions and shocks for 20 oecd nations since 1960 we find that the interaction between shocks and institutions is crucial to explaining both stylised facts

the macroeconomics of specificity specific quasi rents arise in a variety of economic relationships and are exposed to opportunism unless fully protected by contract rent appropriation has important macroeconomic consequences resources are underutilized factor markets are segmented production suffers from technological sclerosis job creation and destruction are unbalanced recessions are excessively sharp and expansions run into bottlenecks while depending on the shock expansions may require reinforcement or stabilization recessions should typically be softened in the long run institutions may evolve to alleviate the problem by balancing appropriation technology choice will also be affected with the appropriated factor partially excluding the other from production to reduce appropriation

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

short and long run elasticities in us residential electricity demand a co integration approach abstract co integration techniques show promise in the analysis of short and long run effects of economic variables on energy use we use these techniques to develop an error correction model of annual us residential electricity demand we construct equipment stock indices and estimate the model for 1949 1993 our analysis suggests a structural shift in consumption during the 1960s we discuss reasons for this shift report the short and long run elasticities provide forecasts for 1994 1995 and compare the model s forecasts with other published forecasts

contract enforcement and investment a systematic review of the evidence summary this systematic review focuses on the empirical research that evaluates the causal link between contract enforcement and investment the evidence available in a variety of academic media reviewed with established procedures provides some but weak support for the existence of such link during 1990 2010 we only found 19 independent studies that empirically test the relationship and only one that directly examines the effects of an actual institutional reform few of the studies test alternative explanations perform robustness checks or critically assess the findings in sum the broadly accepted hypothesis of direct causation is still awaiting strong empirical backing

the effects on competitiveness of coordinated versus unilateral fiscal policies reducing ghg emissions in the eu an assessment of a 10 reduction by 2010 using the e3me model abstract international competitiveness effects from coordinated and uncoordinated multilateral policies to reduce co 2 emissions from 11 member states of the eu by 2010 are compared with those from unilateral policies to achieve a 10 cut in each member state alone the paper presents the results from four projections using a large scale integrated regionalised e3 model of the eu estimated on time series cross section data 1968 93 with international trade treated as between each member state and a european transport and distribution network the 10 reduction is achieved by additional excise duties incremented every year 1999 to 2010 according to the carbon contents of fuels with special with special treatment of electricity taxed on outputs not inputs with revenues recycled via reductions in employers social security contributions multilateral coordinated policies require a common tax rate of 156 ecu per tonne carbon 1999 prices which rises to an average of 165 ecu per tonne with a wide range between regions when policies are uncoordinated all the tax shift projections show double dividends for emission reduction and employment gain for all member states unilateral policies do not show much carbon leakage but they show smaller gains for output and employment effects for price competitiveness appear to be small and mixed with serious losses appearing only for the netherlands and for metals and chemicals especially for unilateral action

pollution taxes and revenue recycling abstract discussions of environmental policy and the tax system have emphasized the value of pollution tax revenues which can be used to reduce other tax distortions in the economy however by raising private marginal production costs environmental taxes also tend to reduce gdp and exacerbate the welfare costs of conventional taxes for environmental taxes in consumption goods industries the net welfare change from these two effects is negative unless this good is a relatively weak substitute for leisure an estimate for the optimal pollution tax with full revenue recycling is 63 to 78 of marginal environmental damages

child labour in indonesian small industries abstract we analyse the geographic incidence of child labour in small manufacturing firms in indonesia at the village level our unique data set covers virtually all indonesian villages and urban neighbourhoods it allows us to distinguish between demand and supply side determinants of child labour we show by correcting for sample selection that a number of counterintuitive results child labour being unaffected by credit access and school proximity are the result of an interplay between supply and demand side determinants credit access and school proximity reduce child labour supply but simultaneously constitute positive location factors for firms thereby increasing the demand for child labourers to effectively reduce child labour growth oriented policies such as enhancing school and credit facilities should be complemented by policies specifically geared towards increasing school attendance

investment in electricity infrastructure in a small isolated market the case of ireland climate policy is driving an extensive deployment of wind generation in the irish electricity market this study evaluates the cost of increasing wind generation both to the system as a whole and to consumers for 2020 we consider different scenarios on fuel and carbon dioxide permit prices and the extent of electricity interconnection with great britain for a small and isolated electricity system such as ireland a high penetration of wind is economically sound only with increased interconnection to great britain since wind generation would otherwise be curtailed not surprisingly for low fuel prices the least cost scenario contains low levels of wind generation whereas the opposite is true for high fuel prices the findings highlight the importance of interconnection and its operation and governance copyright 2009 oxford university press

the impact of vat introduction on uk residential energy demand an investigation using the cointegration approach abstract over a two year period which started in april 1994 the real price of energy to uk households was expected to rise by 17 5 as a result of value added tax vat introduction the regressive nature of the tax forced the government to limit vat on residential fuel to 8 using a cointegration approach to take account of the non stationarity fuel consumption time series this paper estimates real energy and fuel specific price and income elasticities for the period 1974 1 1994 1 they suggest that natural gas has a positive real energy price elasticity indicating that as real price of energy rises households scrap inefficient heaters and invest in more efficient ones principally natural gas these estimates enable projections to be made of the impact of the introduction of vat and imply a rise in natural gas consumption as a result of the additional vat although at the expense of other less efficient fuels overall residential energy consumption however is unlikely to fall significantly from the tax suggesting that it is an inappropriate way of achieving environmental objectives

carbon taxes and carbon emissions trading this paper surveys the literature on and examples of current implementation of carbon taxes and carbon emission permits it sets out the theoretical basis for these instruments with special reference to the revenue recycling and tax interaction effects this theoretical work concludes that instruments which raise revenue which can be recycled so as to reduce pre existing distortionary taxes are significantly less costly than those which do not the paper then reviews the sizable literature on the distributional effects of these instruments especially with regard to industrial competitiveness and regressive effects on low income groups evaluating attempts to mitigate these where they are perceived as unacceptable the paper concludes that such efforts at mitigation while possible can substantially reduce the efficiency benefits of the instruments the projected costs of carbon taxes depend on a wide range of assumptions this is still a contested area but the paper concludes that on a range of plausible assumptions these costs need not be high finally the paper notes that early evaluations of the environmental effectiveness of carbon taxes have been generally positive this suggests that if concern about anthropogenic climate change continues to increase more countries will introduce carbon taxes and emission permits with the latter increasingly auctioned

promise and pitfalls in the use of secondary data sets income inequality in oecd countries as a case study this paper examines the role of secondary data sets in empirical economic research taking the field of income distribution as a case study we illustrate problems faced by users of secondary statistics showing how both cross country comparisons and time series analysis can depend sensitively on the choice of data after describing the genealogy of secondary data sets on income inequality we consider the main methodological issues and discuss their implications for comparisons of income inequality across oecd countries and over time the lessons to be drawn for the construction and use of secondary data sets are summarized at the end of the paper

energy demand and environmental taxes the case of greece the purpose of this paper is to analyze the effects that energy taxes may have on reducing environmental pollution in greece we study the demand for residential energy for the period 1965 1998 and on the basis of these estimates we make forecasts for co2 emissions in the coming years furthermore we develop alternative scenarios for tax changes and study their effects on co2 emissions according to our findings the harmonization of the greek energy taxes to the average european union levels implies an increase of total co2 emissions by 6 annually if taxes are raised however to the highest european union levels the co2 emissions are restricted significantly these empirical findings may indicate that environmental taxation cannot be the unique instrument for combating pollution

education and human capital externalities evidence from colonial benin colonial benin we investigate the effect of education on living standards occupation and political participation since both school locations and student cohorts were selected with very little information treatment and control groups are balanced on observables we can therefore estimate the effect of education by comparing the treated to the untreated living in the same village as well as those living in villages where no schools were set up we find a significant positive treatment effect of education for the first generation of students as well as their descendants they have higher living standards are less likely to be farmers and are more likely to be politically active we find large village level externalities descendants of the uneducated in villages with schools do better than those in control villages we also find extended family externalities nephews and nieces directly benefit from their uncle s education and show that this represents a family tax as educated uncles transfer resources to the extended family

does the rights hypothesis apply to china abstractusing firm level data from a world bank survey this paper examines how legal development in china relates to various firm decisions i find that a more active court system is associated with more investment more adoption of technology more innovation and more complex transactions specifically when a higher percentage of business disputes are resolved through the court system firms tend to have higher investment rates higher propensities to adopt new automated technology and higher probabilities of developing new products in addition they tend to have more nonlocal sales these findings are consistent with a sophisticated version of the rights hypothesis in which the rule of law eventually replaces relation based governance as a superior governance mechanism i find two limitations of china s legal system the court system does a better job facilitating the growth of state owned enterprises than of private firms and it protects local firms better than nonlocal firms

the economics of changing course implications of adaptability and inertia for optimal climate policy this paper reviews evidence that energy technologies and systems adapt over time to accommodate external pressures that technical innovation and systemic change in the energy sector is largely induced by need and restrained by potentially large transitional costs a simple integrated model of optimal greenhouse gas abatement over time is presented in which the abatement cost depends on both fixed and transitional elements it is shown that the optimal current response and long run prospects differ radically between the classical economic case in which the cost of a given cutback in emissions is fixed exogenously and the adaptive case in which the response is ultimately adaptive but heavily constrained by inertia ie low fixed but high transitional cost if energy systems are indeed to a large degree adaptive the results demonstrate that as compared with the classical non adaptive case long run stabilization of atmospheric co2 may be optimal even with moderate damages from climate change greater near term abatement efforts are justified and the cost of a given delay in response may be several times higher neglect of the issue of induced technical change and other adaptive responses may invalidate the policy implications drawn from most integrated assessment models developed to date

theory general equilibrium and political economy in development economics i discuss the role of economic theory in empirical work in development economics with special emphasis on general equilibrium and political economy considerations i argue that economic theory plays should play a central role in formulating models estimates of which can be used for counterfactual and policy analysis i discuss why counterfactual analysis based on microdata that ignores general equilibrium and political economy issues may lead to misleading conclusions i illustrate the main arguments using examples from recent work in development economics and political economy

a future for carbon taxes abstract carbon taxes have been frequently advocated as a cost effective instrument for reducing emissions however in the practice of environmental policies only six countries have implemented taxes based on the carbon content of the energy products in this paper we evaluate carbon taxes with regard to their competitiveness distributional and environmental impacts the evidence shows that carbon taxes may be an interesting policy option and that their main negative impacts may be compensated through the design of the tax and the use of the generated fiscal revenues

when can carbon abatement policies increase welfare the fundamental role of distorted factor markets abstract this paper employs analytical and numerical models to assess the welfare effects of a revenue neutral carbon tax and nonauctioned carbon emissions permits taking into account preexisting tax distortions in factor markets the presence of preexisting taxes significantly raises the general equilibrium costs of both policies this cost increase is much greater under emissions permits since this policy does not generate revenues to reduce distortionary taxes under our central estimates emissions permits cannot increase welfare unless environmental damages exceed about 18 per ton of carbon in contrast an appropriately scaled carbon tax is welfare improving so long as environmental damages are positive

optimal environmental taxation in the presence of other taxes general equilibrium analyses this paper examines the optimal setting of environmental taxes in economies where other distortionary taxes are present we employ analytical and numerical models to explore the degree to which in a second best economy optimal environmental tax rates differ from the rates implied by the pigovian principle according to which the optimal tax rate equals the marginal environmental damages both models indicate contrary to what several analysts have suggested that the optimal tax rate on emissions of a given pollutant is generally less than the rate supported by the pigovian principle moreover the optimal rate is lower the larger are the distortions posed by ordinary taxes numerical results indicate that previous studies may have seriously overstated the size of the optimal carbon tax by disregarding pre existing taxes this abstract was borrowed from another version of this item

two tales on human capital and knowledge spillovers the case of the us and brazil this article uses a quasi mincerian approach to verify whether the concentration of college educated individuals employed in the business support services sector and in the own sector contributes to increased productivity in other sectors of the economy we estimate the returns to education using data from the 2008 us current population survey march supplement and from the 2008 brazilian household survey this article finds evidence of a positive and significant human capital sectorial spillover effect which is consistent with acemoglu s 1996 conjecture the sectorial concentration of highly educated workers contributes to increase wages for all workers this study also finds evidence of increasing returns to education in brazil and diminishing returns to education in the united states this finding may be explained by differences in supply of skilled workers in both economies in addition the short supply of highly skilled workers in brazil likely explains the importance of the spillover effect fro

sensitivity of price elasticity of demand to aggregation unobserved heterogeneity price trends and price endogeneity evidence from u s data abstract price elasticity estimates of residential electricity demand vary widely across the energy economics and policy literature in this paper we seek to explain these findings using three nationwide datasets from the u s the american housing survey forms eia 861 and the residential energy consumption survey we examine the role of the sample period level of aggregation use of panel data use of instrumental variables and inclusion of housing characteristics and capital stock our findings suggest that price elasticities have remained relatively constant over time upon splitting our panel datasets into annual cross sections we do observe a negative relationship between price elasticities and the average price whether prices are rising or falling appears to have little effect on our estimates we also find that aggregating our data can result in both higher and lower price elasticity estimates depending on the dataset used and that controlling for unit level fixed effects with panel data generally results in more inelastic demand functions addressing the endogeneity of price and or measurement error in price with instrumental variables has a small but noticeable effect on the price elasticities finally controlling for housing characteristics and capital stock produces a lower price elasticity

residential demand for electricity the case of greece this paper examines the determinants of residential electricity consumption in greece over the period 1961 86 the paper presents first a brief description of the evolution of residential electricity consumption then it proceeds in the estimation of elasticities of residential demand for electricity using a single equation model with the ridge regression method the paper concludes that i the residential demand for electricity is price inelastic and income elastic ii there is high substitutability between electricity and lpg iii during the examined period the number of consumers played a very important role in the expansion of electricity consumption in greece and iv there is no regional variation in residential electricity demand

green fiscal reform in sweden econometric assessment of the carbon and energy taxation scheme abstract empirical econometric assessment of environmental policy effectiveness is capable of demonstrating which tools have been helping to achieve the desired effect of reducing harmful emissions or stimulating technological change this paper employs an econometric approach to analyse the effectiveness of energy and carbon taxes in sweden the country which was one of the first to introduce a co2 tax as well as an extensive environmental tax reform the results showed that taken in isolation a co2 tax was not sufficient to result in a significant change in co2 emissions in sweden except in the case of petrol on the other hand energy taxes for coal and lpg have been statistically significantly effective it was also clear that a technological innovation in the form of development of nuclear and hydro energy played a significant role in reducing co2 emissions and higher oil price was also important in reducing national co2 emissions in sweden at the same time renewable energy excluding hydro a more recent innovation has not been a statistically significant driver of co2 emissions reduction perhaps due to the fact that wind and solar play a much lesser role in sweden at the moment the net electricity imports from other countries have contributed positively towards reducing co2 emissions in sweden while the use of coal and biomass tended to increase co2 emissions compared to the ex ante modelling results from the literature review the findings confirm the role of environmental taxation as a viable policy instrument effective in reducing co2 emissions in sweden although point towards a more nuanced picture the paper raises important policy questions focused on the effectiveness of environmental policy tools

the medium run effects of educational expansion evidence from a large school construction program in indonesia this paper studies the medium run consequences of an increase in the rate of accumulation of human capital in a developing country from 1974 to 1978 the indonesian government built over 61 000 primary schools the school construction program led to an increase in education among individuals who were young enough to attend primary school after 1974 but not among the older cohorts 2sls estimates suggest that an increase of 10 percentage points in the proportion of primary school graduates in the labor force reduced the wages of the older cohorts by 3 8 10 and increased their formal labor force participation by 4 7 i propose a two sector model as a framework to interpret these findings the results suggest that physical capital did not adjust to the faster increase in human capital

forecasting energy consumption and energy related co2 emissions in greece an evaluation of the consequences of the community support framework ii and natural gas penetration abstract this study seeks to assess the future demand for energy and the trajectory of co2 emissions level in greece taking into account the impact of the community support framework csf ii on the development process and the penetration of natural gas which is one of the major csf ii interventions in the energy system demand equations for each sector of economic activity traded non traded public and agricultural sector and for each type of energy oil electricity and solid fuels are derived the energy system is integrated into a fully developed macroeconometric model so that all interactions between energy prices and production factors are properly taken into account energy co2 forecasts are then derived based on alternative scenarios for the prospects of the greek economy according to the main findings of the paper the growth pattern of forecast total energy consumption closely follows that of forecast output showing no signs of decoupling as regards co2 emissions they are expected to increase with an annual average rate which is higher than world forecasts

energy demand in greece abstract this paper examines the impact of the two energy crises 1973 74 and 1978 79 on energy demand in greece initially some specific characteristics of energy consumption patterns before and after 1973 are presented and compared then demand parameters for hydroelectric energy liquid fuels and solid fuels were estimated using data for the period 1963 1984 and alternative econometric methods ols 2sls fiml to ensure that estimates do not vary across different estimation methods appropriate tests were used to examine whether a structural change in energy demand has occured following either of the two crises the results indicate that while consumption patterns may be different due to price and income changes after the crises the parameters of energy demand in greece have remained unchanged

the impacts of carbon tax and complementary policies on chinese economy under the pressure of global warming it is imperative for chinese government to impose effective policy instruments to promote domestic energy saving and carbon emissions reduction as one of the most important incentive based policy instruments carbon tax has sparked a lively controversy in china this paper explores the impact of carbon tax on chinese economy as well as the cushion effects of the complementary policies by constructing a dynamic recursive general equilibrium model the model can describe the new equilibrium for each sequential independent period e g one year after carbon tax and the complementary policies are imposed and thus describe the long term impacts of the policies the simulation results show that carbon tax is an effective policy tool because it can reduce carbon emissions with a little negative impact on economic growth reducing indirect tax in the meantime of imposing carbon tax will help to reduce the negative impact of the tax on production and competitiveness in addition giving households subsidy in the meantime will help to stimulate household consumptions therefore complementary policies used together with carbon tax will help to cushion the negative impacts of carbon tax on the economy the dynamic cge analysis shows the impact of carbon tax policy on the gdp is relatively small but the reduction of carbon emission is relatively large

quality of higher education and the labor market in developing countries evidence from an education reform in senegal summary while many studies examine the effect of primary education quality on labor market outcomes in developing countries little is known about the effects at higher levels we exploit the quasi experiment provided by a large scale education reform launched in senegal in 2000 to investigate how quality improvements at the university level affect employment our difference in difference estimates suggest that young high skilled workers experienced a nine percentage point employment gain relative to older workers they are also more likely to have better jobs in the service industry or government suggesting a reduction in the mismatch between the quality of high skilled labor demanded and supplied

a theory of trickle down growth and development this paper develops a model of growth and income inequalities in the presence of imperfect capital markets and it analyses the trickle down effect of capital accumulation moral hazard with limited wealth constraints on the part of the borrowers is the source of both capital market imperfections and the emergence of persistent income inequalities three main conclusions are obtained from this model first when the rate of capital accumulation is sufficiently high the economy converges to a unique invariant wealth distribution second even though the trickle down mechanism can lead to a unique steady state distribution under laissez faire there is room for government intervention in particular redistribution of wealth from rich lenders to poor and middle class borrowers improves the production efficiency of the economy both because it brings about greater equality of opportunity and also because it accelerates the trickle down process third the process of capital accumulation initially has the effect of widening inequalities but in later stages it reduces them in other words this model can generate a kuznets curve

schooling and labor market consequences of school construction in indonesia evidence from an unusual policy experiment between 1973 and 1978 the indonesian government engaged in one of the largest school construction programs on record combining differences across regions in the number of schools constructed with differences across cohorts induced by the timing of the program suggests that each primary school constructed per 1 000 children led to an average increase of 0 12 to 0 19 years of education as well as a 1 5 to 2 7 percent increase in wages this implies estimates of economic returns to education ranging from 6 8 to 10 6 percent

implications of co2 reduction policies for a high carbon emitting economy this paper uses a dynamic computable general equilibrium model to compare the macroeconomic and sectoral impacts of three environmental policies in australia an emissions trading scheme ets an ets combined with technological innovation in the renewable energy sector and a fuel tax as an alternative to the ets overall the impacts of the ets were not significantly adverse although the fuel tax had similar impacts to the ets on key macro variables such as real gdp employment household consumption exports and imports it was however not effective compared to the latter in reducing emissions neither policy led to inflation growth of more than 0 8 for any coal mining and non mining australian state at the sectoral level the gdp growth of energy intensive industries such as coal iron ore steel and coal powered electricity generators is adversely affected while electricity generators who use gas and renewable energy sources and the forestry sector gain it was also found that a 10 technological change in the renewable energy sector over a decade did not significantly improve the outcome when coupled with the ets thus the australian government s industry assistance to invest in low pollution technologies needs to be more aggressive to meet current and future international emission abatement targets

revenue raising vs other approaches to environmental protection the critical significance of pre existing tax distortions using analytical and numerical general equilibrium models we show that preexisting factor taxes produce a tax interaction effect that increases the costs of pollution taxes and quotas under policies that raise revenue and recycle it through cuts in marginal factor tax rates this effect is partially offset by a revenue recycling effect grandfathered pollution quotas such as those used under the 1990 clean air act amendments to regulate electric utilities so2 emissions do not benefit from this offset preexisting taxes raise this regulation s cost by over 70 more than half of this additional cost could be avoided by auctioning quotas and exploiting the revenue recycling effect

education and household welfare abstractusing census data from nepal we examine how the partial derivatives of predicted household welfare vary with parental education we focus on fertility child survival schooling and child labor female education is not as strongly associated with beneficial outcomes as is often assumed male education often matters more and part of the association between female education and welfare is driven by marriage market matching with more educated men controlling for the average education of parental cohorts does not change this finding but when we use educational rank to proxy for unobserved ability and family background the positive association between female education and beneficial outcomes becomes weaker or is reversed for women the association between educational rank and outcomes is strong women who obtain more schooling than their peers in school have fewer children and educate them better in contrast for men the statistical association between education and household welfare remains str

dosis facit effectum why the size of the carbon tax matters evidence from the swedish residential sector abstract after 25 years of gradually increasing its carbon tax sweden now imposes the world s highest tax on carbon dioxide emissions this paper examines the effect of the swedish carbon tax on residential carbon emissions by using european panel data we employ synthetic control methods scms and perform difference in difference did regressions to evaluate the causal impact of carbon taxation on carbon emissions in the residential sector we provide evidence that early 2000s carbon tax augmentation had a causal effect on residential carbon emissions we find that the reduction of residential carbon emissions stemming from the carbon tax augmentation ranges from 200 kg when compared with other countries with a carbon tax of more than 20 euro to 800 kg when compared with countries without a carbon tax of co2 per capita per year hence the evidence suggests that carbon taxation is an effective tool for reducing residential co2 emissions and in turn mitigating climate change

carbon taxes with exemptions in an open economy a general equilibrium analysis of the german tax initiative abstract sectoral exemptions from environmental regulation are applied in many countries to avoid adverse adjustment effects in specific industries the problem with exemptions is that they can make environmental policy more costly our paper analyzes the welfare costs of exemptions in environmental policy together with the issue of unilateral carbon taxes in an open economy several countries within the eu have introduced or contemplated unilateral taxes to reduce anthropogenic co2emissions taxes which are unilaterally imposed in an open economy can have significant impacts on production and employment of energy and export intensive industries to save jobs by maintaining international competitiveness most co2taxation schemes include exemptions for energy and export intensive industries as a compromise between environmental objectives and employment in these sectors this paper shows that such compromises are costly as the tax base narrows the dead weight loss increases our calculations illustrate this point in the framework of a static general equilibrium model for west germany calibrated to 1990 data we evaluate the excess costs of exemptions as a means of saving jobs in specific industries relative to an alternative instrument a uniform carbon tax cum wage subsidy which achieves an identical level of national emissions and employment at a fraction of the cost

review of policies and measures for energy efficiency in industry sector abstract energy efficiency in industry plays key roles in improving energy security environmental sustainability and economic performance it is particularly important in strategies to mitigate climate change the evidence of great potential for cost effective efficiency derived reductions in industrial energy use and greenhouse gas ghg emissions have prompted governments to implement numerous policies and measures aimed at improving their manufacturing industries energy efficiency what can be learned from these many and varied initiatives this paper provides foundation for policy analysis for enhancing energy efficiency and conservation in industry by surveying more than 300 policies encompassing about 570 measures implemented by governments in iea countries brazil china india mexico russia and south africa it outlines the measures main features their incidence of use and their connections with specific technical actions and key stakeholders i e how and where measures affect the energy efficiency of industry it also examines the key features underlying the measures success 1 potential to reduce energy use and co2 emissions cost efficiently 2 ease of policy development execution and assessment and 3 ancillary societal effects
