estimating residential demand for electricity in greece abstract this paper examines the residential demand for electricity in greece the issues of structural stability price and income sensitivity of both long and short run residential demand for electricity in greece were examined employing monthly data over the period 1986 1999 the long run residential demand for electricity is estimated taking into account changes in weather conditions weighted by the size of the population employing multivariate framework analysis a long run residential demand function for electricity sensitive to real income price level and weather conditions is found to exist and the importance of short run deviations is presented using vector error correction model vecm estimation the empirical evidence suggests the presence of a stable residential demand for electricity in greece both in the long and short run periods and the policy implications of such a relationship are presented

young in class implications for inattentive hyperactive behaviour of canadian boys and girls using data from the statistics canada national longitudinal survey of children and youth nlscy this paper investigates the impact of school entry age on inattentive hyperactive behaviours we employ both an across provinces and time difference in differences approach and a within province regression discontinuity design we find that being young in class causes greater inattentive hyperactive behaviour exacerbating any inattentive hyperactive behaviour exhibited prior to school entry these results also hold in sibling fixed effect models we do not find gender differences in the effects although since boys are more likely to be inattentive hyperactive at school entry they are more affected these effects persist into early adolescence

child care policy and the labor supply of mothers with young children a natural experiment from canada in 1997 the provincial government of quebec the second most populous province in canada initiated a new child care policy licensed child care service providers began offering day care spaces at the reduced fee of 5 00 per day per child for children aged 4 by 2000 the policy applied to all children not in kindergarten using annual data 1993 2002 drawn from statistics canada s survey of labour and income dynamics the results show that the policy had a large and statistically significant impact on the labor supply of mothers with preschool children

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

the rationale of the mean standard deviation analysis skewness preference and the demand for money publisher summary this chapter discusses the rationale of the mean standard deviation analysis skewness preference and the demand for money in january 1969 issue of the review of economic studies karl borch and martin feldstein separately criticized the widely used mean variance analysis of portfolio selection borch contended that any system of upward sloping mean standard deviation e s indifference curves can be shown to be inconsistent with the basic axiom of choice under uncertainty he pointed out that one can always pick any two points on an upward sloping indifference curve to represent two bernoulli distributions with probability 1 p of gaining the same amount x in both the cases and probability p of gaining y1 in the case of one distribution and y2 in the case of the second distribution with y2 y1 if the second distribution represents the point to the northeast of the other point then by the dominance axiom the second distribution must be preferred to the first which contradicts the basic meaning of indifference curves feldstein by using a log utility function and a lognormal distribution for investment outcome showed that e s indifference curves for a risk averter need not be convex downwards though upward sloping they would change from convex to concave once the standard deviation of the outcome exceeds the mean multiplied by on the face of it this seems to suggest that risk aversion might decrease as risk is increased beyond a certain extent

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

the importance of engaging residential energy customers hearts and minds abstract in an attempt to reduce the contribution of residential greenhouse gas emissions the eu has implemented a variety of policy measures the focus has been to promote domestic energy efficiency and ultimately a reduction in residential energy demand in this study we estimate residential energy demand using underlying energy demand trend uedt and asymmetric price responses for 14 european oecd countries between 1978 and 2008 our results support the conclusion that policies to reduce residential energy consumption and the consequent emissions need to account for behavioural lifestyle and cultural factors in order to be effective

evaluating the effects of childcare policies on children s cognitive development and maternal labor supply to explore the role of childcare policies in the development of early cognitive skills this paper jointly estimates a cognitive achievement production function and a dynamic discrete choice model of maternal labor supply and childcare decisions using counter actuals from the model i investigate how the designs of two childcare programs head start and childcare subsidies affect the formation of cognitive skills through maternal work and childcare decisions the results suggest large impacts on cognitive skills from expanding head start to current noneligibles and negligible impacts of subsidies on cognitive skills of current eligibles abstract from author

the structure of residential energy demand in greece abstract this paper attempts to shed light on the determinants of residential energy demand in greece and to compare it with some other oecd countries from the estimates of the short run and long run elasticities of energy demand for the period 1965 1999 we find that residential energy demand appears to be price inelastic also we do not find evidence of a structural change probably because of the low efficiency of the energy sector we find however that the magnitude of the income elasticity varies substantially between greece and other oecd countries

increasing earnings inequality and the gender pay gap in canada prospects for convergence this paper retraces the evolution of canadian women s labour force participation and of the gender earnings ratio across the generations to understand better the prospects for gender convergence in pay using data from the public use labour force surveys lfs and administrative annual earnings data from the longitudinal worker files lwf the paper assesses the role of increasing top earnings inequality in the persistence of the gender pay gap having identified a growing role for the under representation of women among top earners the paper then performs an evaluation and critical analysis of existing gender equality policies centred on horizontal occupational gender segregation and discusses alternative policies for the future

effect of lengthening the school day on mother s labor supply this article examines how a policy oriented toward a specific group within the population can have collateral effects on the economic decisions of other groups in 1996 the chilean government approved the extension of the school day from half to full day school this article exploits the quasi experimental nature of the reform s implementation by time municipality and age targeting of the program in order to examine how the maternal labor supply is affected by the childcare subsidy implicit in the lengthening of the school day using data from the chilean socioeconomic household survey and administrative data from the ministry of education for 1990 2011 the authors estimate that on average there is a 5 percent increase in labor participation and employment rates of single mothers with eligible children between 8 and 13 years old with no younger children who are the group that would be mainly affected by the policy no significant labor supply responses are detected among others mothers with eligible children

money for nothing universal child care and maternal employment abstract the strong correlation between child care and maternal employment rates has led previous research to conclude that affordable and readily available child care is a driving force both of cross country differences in maternal employment and of its rapid growth over the last decades we analyze a staged expansion of subsidized child care in norway our precise and robust difference in differences estimates reveal that there is little if any causal effect of subsidized child care on maternal employment despite a strong correlation instead of increasing mothers labor supply the new subsidized child care mostly crowds out informal child care arrangements suggesting a significant net cost of the child care subsidies

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 demand for energy in greece assessing the effects of the community support framework 1994 1999 the paper estimates the demand for energy in greece in the tradable and non tradable sectors and for the three main types of energy namely oil electricity and solid fuel using the estimated demand functions forecasts of the demand for energy until the year 2010 are derived by incorporating the system of demand and energy price equations into a fully fledged annual macroeconometric model the model is subsequently used to forecast the demand for energy and the shares of various forms under alternative assumptions about the effects of the community support framework csf it is found that the demand for energy will be significantly affected by the presence of externalities in the implementation of csf that give rise to positive supply side effects and boost growth in the absence of supply side externalities total energy demand rises by 1 4 above the benchmark non csf scenario with growth inducing externalities total demand will increase at year 2010 by 6 0 above baseline

income and price elasticities of electricity demand aggregate and sector wise analyses abstract cointegration and vector error correction modeling approaches are widely used in electricity demand analysis the study rigorously examines the determinants of electricity demand at aggregate and sectoral levels in pakistan in the backdrop of severe electricity shortages our empirical findings give support to the existence of a stable long run relationship among the variables and indicate that electricity demand is elastic in the long run to both income and price at aggregate level at sectoral level long run income and price elasticity estimates follow this pattern except in agricultural sector where electricity demand is found elastic to output but inelastic to electricity price on the contrary the coefficients for income and price are rather small and mostly insignificant in the short run we employed temperature index price of diesel oil and capital stock at aggregate and sectoral levels as exogenous variables these variables account for most of the variations in electricity demand in the short run it shows that mechanization of the economy significantly affect the electricity demand at macro level moreover elastic electricity demand with respect to electricity price in most of the sectors implies that electricity price as a policy tool can be used for efficient use and conservation

the effect of house energy efficiency programs on the extensive and intensive margin of lower income households investment behavior abstract this paper examines the biggest house energy efficiency retrofit support program in greece which ran during 2011 2015 and approximately fifty thousand households participated we take advantage of an exogenous policy change resulting in cost reduction for households that occurred while the program was running this change substantially increased the subsidy rate for lower income households we find that this effective cost reduction increased the participation rate extensive margin we add to the literature on retrofits by further showing that this change increased substantially the investment amount intensive margin of these lower income households detailed data on a sub sample of households reveal that this increase was driven primarily by window replacement and thermal insulation investments

energy development potential an analysis of brazil abstract this paper develops an indicator for the energy development potential edp of 27 brazilian states this indicator uses data on a state s infrastructure and its supply of and demand for energy the indicator measures the data for three periods the first part of the 1990s which is a period of low economic growth the first part of the 2000s which is a period of high economic growth but with a historical crisis in the brazilian energy sector and 2009 2011 which is a period of economic growth after the energy crisis using a factor analysis we are able to identify three factors for edp they are the demand for energy the supply of renewable energy and the supply of nonrenewable energy we use these factors to classify the brazilian states according to their edp and to perform an exploratory spatial data analysis esda by using the moran indicators and the local indicators of spatial association lisa

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

explaining the decline in the u s employment to population ratio a review of the evidence this paper first documents trends in employment rates and then reviews what is known about the various factors that have been proposed to explain the decline in the overall employment to population ratio between 1999 and 2018 population aging has had a large effect on the overall employment rate over this period but within age group declines in employment among young and prime age adults also have played a central role among the factors with effects that we can quantify based on existing evidence labor demand factors in particular increased import competition from china and the penetration of robots into the labor market are the most important drivers of observed within group declines in employment labor supply factors most notably increased participation in disability insurance programs have played a less important but not inconsequential role increases in the real value of state minimum wages and in the share of individuals with prison records also have contributed modestly to the decline in the aggregate employment rate in addition to the factors whose effects we roughly quantify we identify a set of potentially important factors about which the evidence does not yet allow us to draw clear conclusions these include the challenges associated with arranging child care improvements in leisure technology changing social norms increased use of opioids the growth in occupational licensing and declining labor market fluidity our evidence driven ranking of factors should be useful for guiding future discussions about the sources of decline in the aggregate employment to population ratio and consequently the likely efficacy of alternative policy approaches to increasing employment rates

the impact of child care costs on the labour supply of married mothers evidence from canada this paper provides estimates for canada of the impact of childcare costs on the labor supply of married mothers this is done by linking two microdata sources the 1988 canadian national child care survey and the 1988 labour market activity survey the key results show that the market wage and childcare costs have respectively a significant positive and negative impact on both hours of work and the labor force participation decision by married mothers the childcare cost elasticities for labor force participation and hours of work are reported to be 0 38 and 0 32 respectively

modelling energy demand of developing countries are the specific features adequately captured abstract this paper critically reviews existing energy demand forecasting methodologies highlighting the methodological diversities and developments over the past four decades in order to investigate whether the existing energy demand models are appropriate for capturing the specific features of developing countries the study finds that two types of approaches econometric and end use accounting are commonly used in the existing energy demand models although energy demand models have greatly evolved since the early seventies key issues such as the poor rich and urban rural divides traditional energy resources and differentiation between commercial and non commercial energy commodities are often poorly reflected in these models while the end use energy accounting models with detailed sectoral representations produce more realistic projections as compared to the econometric models they still suffer from huge data deficiencies especially in developing countries development and maintenance of more detailed energy databases further development of models to better reflect developing country context and institutionalizing the modelling capacity in developing countries are the key requirements for energy demand modelling to deliver richer and more reliable input to policy formulation in developing countries

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

the quantitative role of child care for female labor force participation and fertility consistent with facts for a cross section of oecd countries i document that the labor force participation rate of west german mothers with children aged zero to two exceeds the corresponding child care enrollment rate whereas the opposite is true for mothers with children aged three to mandatory school age i develop a life cycle model that explicitly accounts for this age dependent relationship through various types of non paid and paid child care the calibrated version of the model is used to evaluate two policy reforms concerning the supply of subsidized child care for children aged zero to two these counterfactual policy experiments suggest that the lack of subsidized child care constitutes indeed for some females a barrier to participate in the labor market and depresses fertility

joint labor supply and childcare choice decisions of married mothers this paper examines the impact of childcare prices and wage rates on the joint employment and childcare mode center sitter relative and husband choice decisions of married mothers by estimating both a mixed logit and universal logit choice model data are drawn from the 1988 canadian national child care survey and the 1988 labour market activity survey the estimation results show that wages have a positive impact on the probability of choosing any of the working states and that childcare prices for center sitter and relative care reduce the probability of working and using each respective mode of care sensitivity analyses reveal that the wage elasticity for employment is fairly robust across model specifications while the own price elasticity of childcare is sensitive to model specification differing identifying assumptions in the estimation of childcare price equations and sample selection the simulation results show that differences exist in the degree to which government subsidies in the form of wage subsidies targeted childcare subsidies or unconditional childcare subsidies impact on labor supply decisions and decisions to substitute across different modes of care by those mothers already in the labor market

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

children of a policy revolution the introduction of universal child care and its effect on fertility what role does affordable and widely available public child care play for fertility we exploit a major german reform generating large temporal and spatial variation in child care coverage for children under the age of three our precise and robust estimates on birth register data reveal that increases in public child care have significant positive effects on fertility the fertility effects are more pronounced at the intensive than at the extensive margin and are not driven by changes in the timing of births or selective migration our findings inform policy makers concerned about low fertility by suggesting that universal early child care holds the promise of being an effective means of increasing birth rates

an analysis of the greek energy system in view of the kyoto commitments the current state of the greek energy system is analysed together with alternative energy policies a by sector analysis provides an overview of the inputs that have been used for this investigation a combination of a demand forecast performed together with an analysis based on the r markal and wasp iv models give an evaluation of the alternative policies to be applied and a determination of additional measures required in order to achieve the kyoto targets three scenarios are developed depicting the evolution of the greek energy system under alternative policies taking into consideration medium and high oil prices incremental investments and differential costs are then calculated between kyoto and non kyoto scenarios and they are compared to emission permits costs

the electricity consumption and economic growth nexus evidence from greece abstract this paper attempts to cast light into the relationship between electricity consumption and economic growth in greece in a multivariate framework for this purpose we used cointegration techniques and the vector error correction model in order to capture short run and long run dynamics over the sample period 1970 2011 the empirical results reveal that in the long run electricity demand appears to be price inelastic and income elastic while in the short run the relevant elasticities are below unity we also argue that the causal relationship between electricity consumption and economic growth in greece is bi directional our results strengthen the notion that greece is an energy dependent country and well directed energy conservation policies could even boost economic growth furthermore the implementation of renewable energy sources should provide significant benefits ensuring sufficient security of supply in the greek energy system this evidence can provide a new basis for discussion on the appropriate design and implementation of environmental and energy policies for greece and other medium sized economies with similar characteristics

an assessment of the greek incentives scheme for photovoltaics abstract after two years of elaboration a new legislation was enacted in 2006 in greece providing an appealing feed in tariff fit scheme for photovoltaics pvs the response of the market was immediate with more than 7947 licenses having been submitted in less than 2 years time the effectiveness however of an incentives scheme cannot be judged solely by the response of prospective investors aim of this paper is to present and discuss a quantitative assessment of this newly introduced fit law in greece with respect to its attractiveness to investors its effectiveness towards launching a new market its cost efficiency and its ability to lift non economic barriers that led to significant delays in the diffusion of res over the last 10 years

inequality in the distribution of expense allocated to the main energy fuels for mexican households 1968 2006 abstract energy is a decisive and essential factor to provide quality of life technological development related to its use and an economic development overview of a given country this essay presents the expense distribution allocated to the main fuel sources used at mexican households the essay herein was carried out for the 1968 2006 period the main purpose of this essay is to determine the expense allocation of the main energy fuels electricity gas firewood kerosene gasoline the methodology used in this essay is based on the lorenz curves and gini coefficient

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

back to work parental benefits and mothers labor market outcomes in the medium run the authors estimate policy impacts of a generous parental benefit in germany by using a natural experiment and german census data they estimate policy effects for the short run first two years a

sorting through affirmative action three field experiments in colombia the use of affirmative action policies to promote female employment remains debated do affirmative action policies attract female applicants and does that come at the expense of deterring highly

canadian contributions to family economics canadian scholars have made substantial contributions to the relatively new field of family economics these include new models of how men and women match in marriage markets and of how decisions are made in multi person households several were early contributors to the literature on married women s labour supply and labour supply in a family context and helped to develop empirical methods in this area a particular focus has been on the impacts of policy relevant parameters such childcare costs on family labour supply and child well being new work on child development the impact of early life conditions and the processes of intergenerational transmission also highlight the importance of family context in determining economic well being

child care costs and the employment decision of women canadian evidence the authors estimate the joint decision for women with preschool children to engage in paid employment and to purchase market forms of child care the results confirm those found in most u s studies indicating that child care costs exert a significant negative effect on the labor supply of women with children and on their decision to purchase child care as well the expected wage of the mother exerts a significant positive impact on both the decision to purchase market forms of child care and the decision to engage in paid unemployment

public child care and mothers labor supply evidence from two quasi experiments abstract public child care is expected to assist families in reconciling work with family life yet empirical evidence for the relevance of public child care to maternal employment is inconclusive we exploit the introduction of a legal claim to a place in kindergarten in germany which was contingent on day of birth cut off dates and resulted in a marked increase in kindergarten attendance of three year olds in the following years instrumental variable and difference in differences estimations on two individual level data sets yield positive effects of public child care on maternal employment a set of placebo treatment tests corroborate the validity of our identification strategies

employment and child care choices in canada and the united states in this paper we examine employment and child care choices of two parent families with young children in the united states and canada using a pooled data set based on recent national surveys in each country we find that the employment and child care choices of canadian families are similar to those of u s families estimates of a model of employment and child care choices indicate significant effects of child care subsidies child care prices and wage rates on employment and child care choices however none of these factors helps to explain the differences in employment and child care choices between the two countries ce memoire examine le choix de l emploi et du soin des enfants dans les familles ou il y deux parents aux etats unis et au canada en utilisant des donnees d etudes recentes dans les deux pays il appert que les choix des familles canadiennes sont semblables a ceux des familles americaines les calibrations d un modele de ces choix montrent les effets significatifs des subventions au soin des enfants du prix des soins des enfants et des taux de salaires sur ces choix cependant aucun de ces facteurs n explique les diffrences dans les patterns de choix entre les deux pays

optimising criminal behaviour and the disutility of prison we use rich microdata on bank robberies to estimate individual level disutilitiesities of imprisonment the identification rests on the money versus apprehension trade off that robbers face inside the bank when deciding whether to leave or collect money for an additional minute the distribution of the disutility of prison is not degenerate generating heterogeneity in behaviour our results show that unobserved heterogeneity in robber ability is important for explaining outcomes in terms of haul and arrest furthermore higher ability robbers are found to have larger disutilities suggesting that increased sentence lengths might effectively target these more harmful criminals

childcare effects on maternal employment evidence from chile abstract using a randomized experiment this study examines whether offering afterschool care for children aged between 6 and 13 has an impact on labor market outcomes for women in chile the results show that program participation increases employment by 5 and labor force participation by 7 while the intervention also generates substantial childcare substitution the results also suggest that the provision of afterschool care for older children triggers the use of free daycare for young ineligible children

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

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

conceptualizing urban household energy use climbing the energy services ladder this article begins by defining energy services and identifying how they differ according to sector urban and rural areas and direct and indirect uses it then investigates household energy services divided into three classes lower income middle income and upper income it finds that the primary energy technologies involved with low income households involve a greater number of fuels and carriers ranging from dung and fuelwood to liquefied petroleum gas and charcoal but a fewer number of services middle income households throughout the world tend to rely on electricity and natural gas followed by coal liquefied petroleum gas and kerosene these homes utilize energy to produce a much broader range services the upper class or rich have access to the same energy fuels carriers and technologies as middle income homes and families but consume more energy and more high luxury items the study highlights how focusing on energy services reorients the direction of energy policy interventions that energy services are neither uniform nor innate and by noting exciting areas of potential research

new estimates of labour supply elasticities for married women in canada 1996 2005 in this article we estimate income and substitution labour supply and participation elasticities for canadian married women using data from the survey of labour and income dynamics 1996 2005 we use the canadian tax and credit simulator ctacs and detailed information on the structure of income at the household level to compute the marginal tax rates faced by each individual we then use these marginal tax rates to compute net own wage spouse wage and nonlabour income we show how the magnitude of the estimated elasticities varies depending on whether net or gross wages and income are used in the estimation procedure and quantify biases caused by using average tax rates instead of marginal tax rates finally because marginal tax rates vary significantly over the sample we use quantile regressions to compare elasticities at different points of the hours distribution overall our results show that public policies now have on average less scope for influencing hours of work than 10 years ago howev

the educational and labor market returns to preschool attendance in austria preschool attendance is widely recognized as a key ingredient for later socioeconomic success mothers labor market participation and leveling the playing field for children from disadvantaged backgrounds however the empirical evidence for these claims is still relatively scarce particularly in europe using data from the 2011 austrian european union statistics of income and living conditions eu silc we contribute to this literature by studying the effects of having attended preschool for the adult austrian population we find strong and positive effects of preschool attendance on later educational attainment the probability of working full time hourly wages and the probability that the mother is in the labor market full time workers at the bottom and the top of the distribution benefit less than those in the middle women in particular benefit more in terms of years of schooling and the probability of working full time other disadvantaged groups second generation migrants people with less educated parents also often benefit more in terms of education and work

public schooling for young children and maternal labor supply as policy makers have sought to reduce the welfare rolls by increasing labor supply among single mothers much attention has been given to the possible role of expanded child care subsidies including direct provision of public preschool at the same time public interest in child care subsidies for two parent households is high for example former vice president gore not long ago proposed to make high quality pre school fully available to every family for every child in every community in america albert gore 1999 in this paper i use 1980 census data to estimate the effect of public school enrollment for a woman s five year old on measures of labor supply and public assistance receipt this approach has two advantages first i am able to estimate the effect of a large implicit child care subsidy 1 second because public kindergarten is universally available to all age eligible children where it is provided selection problems related to means testing do not arise a difficulty with public school enrollment arises because parents may choose to hold their children back a year or enroll them in private school i deal with this issue by using five yearold s quarter of birth qob variables as instruments for public school enrollment status this strategy works because parents ability to enroll a child in public kindergarten in the academic year when the child turns five typically depends on the calendar date of the child s birth 2 in most states children born in the second quarter april 1 june 30 of 1974 will have been eligible to start kindergarten in the fall of 1979 while children born in the first quarter january 1march 31 of 1975 generally will not eligibility for children born between july 1 and december 31 1974 depends on the rules where they live 3

the effect of universal child benefits on labour supply using a difference in differences estimator i find the canadian universal child care benefit has significant negative income effects on the labour supply of married individuals the likelihood of lower educated mothers to participate in the labour force is reduced 3 2 percentage points when receiving the benefit median hours worked per week among lower educated mothers is reduced by 1 9 hours the effects on higher educated mothers are substantial with median hours worked among higher educated mothers reduced by nearly one hour per week for men the evidence suggests small but significant income effects on labour supply consistent with the literature on labour supply elasticities

early kindergarten maternal labor supply and children s outcomes evidence from italy abstract we analyze a reform that introduced early access to subsidized childcare for 2 year old children in italy exploring the effects on several measures of maternal labor supply and on children s cognitive outcomes our identification strategy exploits discontinuities in the eligibility rules and the staggered implementation of the reform we find that the policy increased mothers participation in the labor market and lowered the reservation wage of the unemployed thus increasing their likelihood of finding a job at the same time the newly introduced childcare arrangement did not affect children s cognitive development irrespective of their family background

welfare the earned income tax credit and the labor supply of single mothers during 1984 1996 welfare and tax policy were changed to encourage work by single mothers the earned income tax credit was expanded welfare benets were cut welfare time limits were added and welfare cases were terminated medicaid for the working poor was expanded as were training programs and child care during this same time period there were unprecedented increases in the employment and hours of single mothers we show that a large share of the increase in work by single mothers can be attributed to the eitc and other tax changes with smaller shares for welfare benet cuts welfare waivers training programs and child care programs
