does the gap in family friendly policies drive the family gap a segregation of the labour market into a family friendly and a non family friendly sector has the effect that women self select into the sectors depending on institutional constraints preferences for family friendly working conditions and expected wage differences we find that neglecting the sector dimension tends to understate the effect of birth related interruptions in both sectors the combined effect of a large depreciation effect and no recovery means that females in the non family friendly sector e g private sector are punished severely after childbirth in the family friendly sector e g public sector we find complete catch up

energy conservation more effective with rebound policy this article sketches the problem of indirect energy use effects also known as rebound of energy conservation there is widespread support for energy conservation especially when it is voluntary as this seems a cheap way to realize environmental and energy climate goals however this overlooks the phenomenon of rebound the topic of energy rebound has mainly attracted attention from energy analysts but has been surprisingly neglected in environmental economics even though economists generally are concerned with indirect or economy wide impacts of technical change and policies this paper presents definitions and interpretations of energy and environmental rebound as well as four fundamental reasons for the existence of the rebound phenomenon it further offers the most complete list of rebound pathways or mechanisms available in the literature in addition it discusses empirical estimates of rebound and addresses the implications of uncertainties and difficulties in assessing rebound suggestions are offered for strategies and public policies to contain rebound it is advised that rebound evaluation is an essential part of environmental policy and project assessments as opposed to earlier studies this paper stresses the relevance of the distinction between energy conservation resulting from autonomous demand changes and from efficiency improvements in technology equipment in addition it argues that rebound is especially relevant for developing countries

understanding the family gap in pay for women with children as the gender gap in pay between women and men has been narrowing the family gap in pay between mothers and nonmothers has been widening one reason may be the institutional structure in the united states which has emphasized equal pay and opportunity policies but not family policies in contrast to other countries that have implemented both the authors now have evidence on the links between one such family policy and women s pay recent research suggests that maternity leave coverage by raising women s retention after childbirth also raises women s levels of work experience job tenure and pay

marriage motherhood and wages we explore several problems in drawing causal inferences from cross sectional relationships between marriage motherhood and wages we find that heterogeneity leads to biased estimates of the direct effects of marriage and motherhood on wages i e effects net of experience and tenure first difference estimates reveal no direct effect of marriage or motherhood on women s wages we also find statistical evidence that experience and tenure may be endogenous variables in wage equations instrumental variables estimates suggest that both ordinary least squares cross sectional and first difference estimates understate the direct negative effect of children on wages

energy rebound effect in china s industry an aggregate and disaggregate analysis abstract considering the crucial role of industrial sectors in energy conservation this paper investigates the impact of output growth on energy consumption in china s industrial sectors with an index decomposition model and the energy rebound effect in the industrial sectors with a panel data model using the annual data during 1994 2012 the empirical results indicate that first industrial output growth is proved to be the major factor in promoting industrial energy consumption while energy intensity reduction and structure shifts across industrial sub sectors play the dominant roles in slowing down industrial energy consumption second there does exist energy rebound effect in china s aggregate industry which ranges from 20 to 76 during 1995 2012 or 39 on average in particular the energy rebound effect in manufacturing is relatively smaller during the sample period i e 28 on average finally the energy rebound effect in both china s aggregate industry and manufacturing exhibit an overall decreasing trend over time

linking consumer energy efficiency with security of supply most modern energy policies seek to achieve systematic ongoing incremental increases in consumer energy efficiency since this contributes to improved security of supply favourable environmental outcomes and increased economic efficiency yet realised levels of efficiency are typically well below the most cost effective equilibrium due to variety of behavioural and organisational barriers which are often linked to information constraints in addition efficient users are normally unrewarded for collective benefits to system security and to the environment thus reducing the incentives for energy consumers to invest in efficiency improvements this paper examines the dichotomies and symmetries between supply and demand side solutions to energy security concerns and reviews opportunities to overcome barriers to improved consumer efficiency a security market is identified as a mechanism to promote both demand and supply side investments that support electricity system security such a market would assist in setting the optimal quantity of reserves while achieving an efficient balance between supply and demand side initiatives it would also help to smooth overall investment throughout the energy system by encouraging incremental approaches such as distributed generation and demand side alternatives where they provide competitive value although the discussion is applicable to energy systems in general it focuses primarily on electricity in new zealand

in and out of the labour market long term income consequences of child related interruptions to women s paid work why do canadian mothers have lower incomes than women who have never had children microdata from the 1995 gss allow examination of two hypotheses 1 mothers have spent more time out of the labour force thus acquiring less human capital 2 higher levels of unpaid work lead to fatigue and or scheduling difficulties measuring work history does little to account for the family gap the estimated child penalty is reduced by allowing for human capital depreciation and controlling for unpaid work hours but the two hypotheses together cannot entirely explain the gap jel classification j0 j3 entrees et sorties marche du travail et consequences a long terme des interruptions dans l experience sur le marche du travail a cause des enfants ce memoire se demande pourquoi les femmes canadiennes qui ont eu des enfants ont des revenus plus bas que ceux des femmes qui n en ont pas eus les microdonnees de l enquete sociale generale de 1995 de statistiques canada permettent d examiner deux hypotheses 1 les meres ont passe plus de temps en dehors de la main d oeuvre active et donc ont accumule moins de capital humain ou 2 des niveaux plus eleves de travail non remunere peuvent entrainer fatigue ou difficultes d organisation du temps des efforts pour construire une meilleure image de l experience de travail des femmes ne permettent pas d expliquer cet ecart familial meme si la possibilite qu il y ait depreciation du capital humain reduit la penalisation attachee au fait d avoir un enfant en particulier si l interruption dans l experience sur le marche du travail est suivie d un changement d emploi le nombre hebdomadaire d heures de travail non paye est relie negativement aux revenus et si l on normalise pour tenir compte des heures de travail non paye cela reduit la penalisation attachee au fait d avoir un enfant cependant les deux hypotheses combinees ne suffisent pas pour expliquer l ecart

the family gap for young women in the united states and britain can maternity leave make a difference in the united states and britain there is a family gap between the wages of mothers and other women differential returns to marital and parental status explain 40 50 of the gender gap another 30 40 is explained by women s lower levels of work experience and lower returns to experience taking advantage of quasi experiments in job protected maternity leave in the united states and britain this article finds that women who had leave coverage and returned to work after childbirth received a wage premium that offset the negative wage effects of children

the effect of sibling sex composition on women s education and earnings this paper documents the impact of siblings on the education of men and women born in the united states between 1920 and 1965 we examine the effect of the number and sex composition of a boy or girl s siblings on that child s educational attainment we find that throughout the century women s educational choices have been systematically affected by the sex composition of her siblings and that men s choices have not women raised only with brothers have received on average significantly more education than women raised with any sisters controlling for household size since sibling sex composition affects women s educational attainment and plausibly may be unrelated to other determinants of earnings it may provide a useful instrument for education in earnings functions for women our results suggest that standard estimates significantly underestimate the return to schooling for women

cash transfers and high food prices explaining outcomes on ethiopia s productive safety net programme an ongoing and highly politicised debate concerns the relative efficacy of cash transfers versus food aid this paper aims to shed light on this debate drawing on new empirical evidence from ethiopia s productive safety net programme psnp our data derive from a two wave panel survey conducted in 2006 and 2008 ethiopia has experienced unprecedented rates of inflation since 2007 which have reduced the real purchasing power of psnp cash payments our regression findings confirm that food transfers or cash plus food packages are superior to cash transfers alone they enable higher levels of income growth livestock accumulation and self reported food security these results raise questions of fundamental importance to global humanitarian response and social protection policy we draw out some implications for the design of social transfer programmes and describe some steps that could be taken to enable predictable transfers to meet predictable needs

electricity restructuring greenhouse gas emissions efficiency and employment reallocation abstract this paper focuses on demonstrating the feedback relationships between greenhouse gas emissions efficiency in the electricity sector and employment reallocation with a consideration of the effects of electricity restructuring and socio demographic factors we postulate the construction information manufacturing utilities and mining sectors as a group of emissions efficiency related industries and identify the mutual relationships the emissions efficiency positively influences the job shares of these industries except mining whereas increased employment in these industries has a negative effect on the emissions efficiency electricity restructuring has a positive effect on overall employment however it does not have a statistically significant effect on the emissions efficiency additionally population aging and educational attainment have positive effects on the emissions efficiency and a higher proportion of rental households has a negative influence on it increases in renewable energy and nuclear energy generation have elastic effects on enhancing emissions efficiency

the costs of motherhood an analysis using matching estimators we estimate the effect of motherhood on wages using matching we distinguish between net and direct effects the net effect includes the total wage costs whereas the direct represents the causal effect since covariates are likely affected by motherhood the latter effect is not immediately uncovered we therefore implement two strategies first we confine the analysis to consider sector specific treatment effects second we impose additive separability on the outcome equation we find negative net effects that vary little with sector the direct effect is small and negative in the public sector and insignificant in the private sector copyright 2006 john wiley sons ltd

international spillover and rebound effects from increased energy efficiency in germany the pollution energy leakage literature raises the concern that policies implemented in one country such as a carbon tax or tight energy restrictions might simply result in the reallocation of energy use to other countries this paper addresses these concerns in the context of policies to increase energy efficiency rather than direct action to reduce energy use using a global cge simulation model we extend the analyses of economy wide rebound from the national focus of previous studies to incorporate international spill over effects from trade in goods and services our focus is to investigate whether these effects have the potential to increase or reduce the overall global rebound of local energy efficiency improvements in the case we consider increased energy efficiency in german production generates changes in comparative advantage that produce negative leakage effects thereby actually rendering global rebound less than national rebound

a view from the macro side rebound backfire and khazzoom brookes abstract this paper attempts to delineate a few key insights extracted from theoretical macroeconomic considerations of the rebound issue the goal has been to reduce these thoughts to a clear set of assertions that if true would be useful points of reference in the ongoing discussion despite their non empirical nature

digitalization and energy consumption does ict reduce energy demand abstract this article investigates the effect of digitalization on energy consumption using an analytical model we investigate four effects 1 direct effects from the production usage and disposal of information and communication technologies ict 2 energy efficiency increases from digitalization 3 economic growth from increases in labor and energy productivities and 4 sectoral change tertiarization from the rise of ict services the analysis combines empirical and theoretical findings from debates on decoupling energy consumption from economic growth and from debates on green it and ict for sustainability our main results effects 1 and 3 tend to increase energy consumption effects 2 and 4 tend to decrease it furthermore our analysis suggests that the two increasing effects prevail so that overall digitalization increases energy consumption these results can be explained by four insights from ecological economics a physical capital and energy are complements in the ict sector b increases in energy efficiency lead to rebound effects c ict cannot solve the difficulty of decoupling economic growth from exergy d ict services are relatively energy intensive and come on top of former production in future digitalization can only boost sustainability when it fosters effects 2 and 4 without promoting effects 1 and 3

sustainability in a post keynesian growth model for an open economy the paper expands the bop constraint growth model and kaldorian regimes productivity and demand regimes in order to include some of the concerns raised by ecological economics in post keynesian models for open economies the demand regime is modified by taking into account porter s hypothesis which suggests that environmental innovations spurred by environmental policies can foster competitiveness as a result the equilibrium bop constrained rate of growth increases leading to a different version of thirlwall s law which opens room for analyzing the impact of environmental innovations on convergence between developing and developed economies the productivity regime in turn considers the growth and employment implications of innovations in labor productivity standard innovations and environmental efficiency environmental innovations it is argued that the fiscal policy and composition of public expenditure matter for long run growth employment and sustainability

economy wide rebound effects for non energetic raw materials material efficiency is increasingly being seen as a means to save resources and achieve greater security of supply whether these aims can be achieved to the desired extent depends among other things on the presence of rebound effects this article estimates economy wide rebound effects for non energetic raw materials in the context of a set of material efficiency projects carried out in germany under the assumption that the efficiency technologies developed in these projects are scaled up to the national level input output analysis is used to calculate changed material requirements and corresponding rebound effects reduced material flows in monetary terms together with economic data are aggregated to an economy wide impulse which can cause re increases in the demand for the considered raw materials depending on the project specific framework conditions and subject to the modeling assumptions our estimates suggest that individual materials display a wide range of rebound effects ranging from close to zero to low double digit percentages these results point towards the conclusion that economy wide rebound effects do not make these efficiency measures obsolete however they also suggest that rebound effects should not be ignored in the assessment of the role of efficiency in future resource consumption

rebound and disinvestment effects in refined oil consumption and supply resulting from an increase in energy efficiency in the scottish commercial transport sector in this paper we use an energy economy environment computable general equilibrium cge model of the scottish economy to examine the impacts of an exogenous increase in energy augmenting technological progress in the domestic commercial transport sector on the supply and use of energy we focus our analysis on scottish refined oil as the main type of energy input used in commercial transport activity we find that a 5 increase in energy efficiency in the commercial transport sector leads to rebound effects in the use of oil based energy commodities in all time periods in the target sector and at the economy wide level however our results also suggest that such an efficiency improvement may cause a contraction in capacity in the scottish refined oil supply sector this disinvestment effect acts as a constraint on the size of rebound effects however the magnitude of rebound effects and presence of the disinvestment effect in the simulations conducted here are sensitive to the specification of key elasticities of substitution in the nested production function for the target sector particularly the substitutability of energy for non energy intermediate inputs to production

the rebound effect some empirical evidence from india abstract the present paper looks at the effect of technical efficiency gains on energy use in three sectors in india at varying levels of aggregation high positive rebound implies that efficient technology unless supplemented by appropriate pricing policy will not be successful in containing demand however the main purpose of the paper is to focus on the unique mechanism of rebound that may occur in developing countries with unmet demand

why do tougher caseworkers increase employment the role of programme assignment as a causal mechanism abstract previous research found that less accommodating caseworkers are more successful in placing unemployed workers into employment this paper explores the causal mechanisms behind this result using semi parametric mediation analysis analyzing rich linked job seeker caseworker data for switzerland we find that the positive employment effects of less accommodating caseworkers are not driven by a particularly effective mix of labor market programs but rather by other dimensions of the counseling process possibly including threats of sanctions and pressure to accept jobs

china s carbon dioxide emissions an interprovincial comparative analysis of foreign capital and domestic capital abstract against the background of china s further relaxation of foreign investment control and implementation of energy conservation and emissions reduction the data of 30 provinces in china from 2001 to 2015 were used to measure the carbon dioxide emissions levels foreign direct investment stock and domestic capital stock in various regions the impulse response function variance decomposition and panel causality test in the panel vector autoregressive model evaluated in detail the impact of foreign capital inflows domestic capital inputs and economic growth on co2 emissions in regions of different energy intensity the study found that on the whole foreign direct investment has no significant impact on china s carbon dioxide emissions china s carbon dioxide emissions are mainly driven by domestic investment and economic growth the sub regional analysis based on different energy intensities shows that in areas of low energy intensity and medium energy intensity foreign direct investment has a significant impact on co2 emissions and the contribution of foreign investment to co2 emissions is between 12 2 and 14 1 the panel causality test found that in the short term foreign direct investment and domestic capital have significant predictive effects on carbon dioxide in various regions
