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

does education affect risk aversion evidence from the british education reform individual risk attitudes are frequently used to predict decisions regarding education however using risk attitudes as a control variable for decisions about education has been criticized because of the potential for reverse causality causality between risk aversion and education is unclear and disentangling the different directions it may run is difficult in this study we make the first attempt to investigate the causal effects of education on risk aversion by examining the british education reform of 1972 which increased the duration of compulsory schooling from age 15 to age 16 using regression discontinuity design we find that this additional year of schooling increases the level of risk aversion which is contrary to previous findings in the literature and we also find that this result is particularly strong for individuals with less education this positive causal effect of education on risk aversion might alleviate concerns regarding the endogeneity reverse causality issue when using risk aversion as an explanatory variable for decisions about education the sign would remain credible because the coefficients are underestimated

parastatal pay policy in africa abstract public enterprises have grown to represent a significant share of modern sector employment in many african economies with wage and employment issues near the top of the policy agenda in africa attention should be given to public enterprise compensation and employment policies after describing the institutions which govern public enterprise pay in a number of sub saharan countries the paper considers the policy dilemma in choosing between the two basic alternative pay setting regimes for public enterprise enterprise wage autonomy versus unified salary scales with the civil service

is education always reducing fertility evidence from compulsory schooling reforms we study the relationship between education and fertility exploiting compulsory schooling reforms in england and continental europe implemented between 1936 and 1975 we assess the causal effect of education on the number of biological children and the incidence of childlessness while we find a negative relationship between education and fertility in england this result can not be confirmed for continental europe the additional education generated by schooling expansions on the continent did not lead to a decrease in the number of biological children nor to an increase in childlessness these findings are robust to a number of sensitivity and falsification checks author s abstract

market segmentation and willingness to pay for green electricity among urban residents in china the case of jiangsu province the objective of this study is to identify market segments and estimate the residents willingness to pay wtp for green electricity green e in china for the large scale promotion of energy projects from renewable sources that do not rely solely on energy policies based on an analysis of non use values of green e as well as the application of the contingent valuation cv method and payment card pc introduction technology the average wtp ranges from rmb 7 91 yuan month to 10 30 yuan month approximately us 1 15 1 51 month with an exchange rate of 6 83 yuan us yuan us for urban residents in jiangsu province the current work also explores the differences in demographic variables across varying wtp amounts and the different marginal effects of demographic variables at the same level of wtp the findings reveal that there are significant differences in demographic variables such as level of education household income and location of residence across the population segments moreover the finding that some respondents with high income and higher education prefer higher wtp amounts to lower wtp amounts suggests that green e is a luxury product and consequently a veblen effect exists in certain chinese market segments

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

low natural gas prices and the financial cost of ramp rate restrictions at hydroelectric dams abstract peaking hydroelectric dams that employ variable stop start reservoir releases can have adverse impacts on downstream river ecosystems efforts to mitigate these impacts have relied predominantly on the use of ramp rate restrictions which limit the magnitude of hour to hour changes in reservoir discharge ramp rate restrictions shift hydropower production towards less valuable off peak hours imposing a financial penalty on dam owners that is a function of the spread difference between peak and off peak electricity prices this study examines how low natural gas prices in the u s have reduced the cost of implementing ramp rate restrictions at dams by narrowing the peak off peak price spread significantly lower costs of ramp rate restrictions could open new opportunities for improving environmental flows at dams including the purchase of more natural streamflow patterns by downstream stakeholders a type of arrangement for which there is growing precedent we also explore the role that uncertainty in the cost of ramp rate restrictions could play in precluding downstream stakeholders from forming these types of agreements with dam owners results suggest that financial collar contracts could mostly eliminate inter annual variability in the net cost of restrictions and provide those purchasing more natural flows with greater certainty

environmental pricing of externalities from different sources of electricity generation in chile abstract the rapid increase in electricity demand in chile means a choice must be made between major investments in renewable or non renewable sources for additional production current projects to develop large dams for hydropower in chilean patagonia impose an environmental price by damaging the natural environment on the other hand the increased use of fossil fuels entails an environmental price in terms of air pollution and greenhouse gas emissions contributing to climate change this paper studies the debate on future electricity supply in chile by investigating the preferences of households for a variety of different sources of electricity generation such as fossil fuels large hydropower in chilean patagonia and other renewable energy sources using double bounded dichotomous choice contingent valuation a novel advanced disclosure method and internal consistency test are used to elicit the willingness to pay for less environmentally damaging sources policy results suggest a strong preference for renewable energy sources with higher environmental prices imposed by consumers on electricity generated from fossil fuels than from large dams in chilean patagonia policy results further suggest the possibility of introducing incentives for renewable energy developments that would be supported by consumers through green tariffs or environmental premiums methodological findings suggest that advanced disclosure learning overcomes the problem of internal inconsistency in sb db estimates

a target group specific approach to green power retailing students as consumers of renewable energy an extensive body of literature exists on the obstacles that have to be overcome in green power retailing in this article target group specific marketing is evaluated as a strategy to increase the share of residential customers of green power a sample of students in the city of freiburg germany was interviewed in order to assess their awareness of environmental issues their willingness to change to green power products and to better understand individual hindrances in changing the power supplier the analysis shows that students are highly positive towards green power products but for several reasons difficult to reach in marketing campaigns aspects to be considered in addressing this consumer group include the students particular expectations towards green products their living conditions price sensitivity and their perception of the relative effort involved in changing the power provider

on the economics of ramping rate restrictions at hydro power plants balancing profitability and environmental costs this paper examines the impact of ramping rate restrictions imposed on hydro operations to protect aquatic ecosystems a dynamic optimization model of the profit maximizing decisions of a hydro operator is solved for various restrictions on water flow using data for a representative hydro operation in ontario profits are negatively affected but for a range of restrictions the impact is not large ramping restrictions cause a redistribution of hydro production over a given day which can result in an increase in total hydro power produced this affects the need for power from other sources with consequent environmental impacts

getting the safe minimum standard to work in the real world a case study in moral pragmatism abstract there is growing endorsement of local stake holder conventions to resolve unusual environmental disputes the conventions are separate decision making bodies designed to by pass conventional institutions the hazards of a stake holder convention which is overly detached from conventional decision making leads to a discourse that never successfully confronts the value controversies which the stake holder convention is charged to resolve a case study uncovers obvious and robust strategic manipulations of stake holder conventions that intrude on value dialogue an appeal to the safe minimum standard rules of ciriacy wantrup updated to engage this question successfully corrects some of the more egregious stumbling blocks to good faith dialogue in local discourse the proposed constraints on the stake holder convention can be quite directive authoritative and bureaucratic yet the constraints are necessary to preserve good faith conduct within the dialogue

internal adjustments to falling civil service salaries insights from uganda abstract real basic salaries of civil servants in many developing countries have fallen during the past 15 years little is known however as to how the civil service personnel structure and pay system have responded to the salary cuts civil service basic salaries fell drastically in uganda during 1975 1988 the adaptive responses of the civil service are identified allowances have not increased to cushion the salary cuts as is alleged to have happened in many developing countries the adaptive responses have had negative effects on efficiency and equity within the civil service they have reversed the decline in the public wage bill the raison d etre for deep salary slashes in the first place

social demand for electricity from forest biomass in spain does payment periodicity affect the willingness to pay in this article we analyze social preferences for a partial substitution programme of electricity generated by conventional energy sources for energy generated from a local renewable energy source such as forest biomass this analysis sets arguments in favour of accelerating the introduction of this renewable technology in the spanish electricity system simultaneously two methodological goals concerning the contingent valuation method are discussed in the first one we analyze if there are statistical differences in the willingness to pay wtp when a single or a double bounded format is employed to ask the valuation question results show that wtp estimates from single and double bounded significantly differ in the second one we analyze the effect of the periodicity of the payment vehicle on the estimates of welfare change the timeframe specification of the payment vehicle has been scarcely studied and this fact constitutes the main contribution of this paper to the specialized literature results show that periodicity influences upon the probability to favour the proposed change the periodicity does not affect to the mean wtp obtained in the single bounded format but there are statistical differences in the double bounded format these results might be explained by the presence of yea saying and payment scale bias

investments in human capital wage uncertainty and public policy abstract the importance of risk characteristics of human capital for the design of tax and education policy is explored wages are uncertain and education while increasing the expected wage may increase or decrease wage variance the government has strong reasons to encourage human capital formation in the latter case partly due to the insurance effect of human capital and partly due to the way the individuals under a plausible restriction on prudence respond to changes in risk the analysis is illustrated using two models of education one where education helps the individuals make better occupational choices and a standard risk augmented becker type model

the leadership factor in african policy reform and growth in 1997 the world bank s two vice presidents for sub saharan africa attributed a significant improvement in africa s growth prospects to a new generation of leaders replacing their once largely statist and corrupt predecessors of 48 african leaders holding office on 1 january 1999 22 were in power a decade earlier and eight ten years before that examination of ten countries with focus on kenya and zambia raises the question why after these incumbents had created such an economic catastrophe were socio political structures unable to replace them with better leaders there are no clear answers the literature on the political economy of economic reform has tended to focus on interest group analysis with only a few studies according a major role to the emergence of individuals whose vision and initiative launch their countries onto paths of rapid growth promoting reform in africa encounters many difficulties yet there is increasing evidence that action by national leaders to raise agricultural production and promote the export of labor intensive manufactures would greatly enhance the prospects for accelerated growth the paper urges other social scientists to help us learn more about how african social structures can create power bases for individuals with the vision to promote and sustain economic reform

neopatrimonialism and the political economy of economic performance in africa critical reflections during the past two decades neopatrimonialism has become the convenient all purpose and ubiquitous moniker for african governance the school of thought behind this research program which the author refers to as the neopatrimonialism school has produced an impressive literature on africa its analysis informs policymakers and its language permeates media reportage on african states while neopatrimonialism has long been a focus of development studies in recent times it has assumed politically and economically exigent status the school identifies causal links between neopatrimonialism and economic performance and makes predictions drawing from what is referred to as the logic of neopatrimonialism neopatrimonialism is said to account for trade policies hyperinflation economic stagnation low investment in infrastructure urban bias andultimately the lack of economic development in africa this article examines the empirical basis of predictions and policy prescriptions it argues that while descriptive of the social practices of the states and individuals that occupy different positions within african societies the concept of neopatrimonialism has little analytical content and no predictive value with respect to economic policy and performance

consumers willingness to pay for green electricity a meta analysis of the literature at present electricity generated from power plants using renewable sources costs more than electricity generated from power plants using conventional fuels consumers bear these expenses directly or indirectly through higher prices for renewable energy or taxes the number of studies published over the last few years focusing on people s preferences for renewables has increased steadily making it more and more difficult to identify key explanatory factors that determine people s willingness to pay wtp for renewables we present results of a meta regression on valuation of consumer preferences for a larger share of renewable energy in their electricity mix our meta regression results reveal a number of important factors that explain the differences in wtp values for renewable energy different valuation methods show widely different values with choice experiments producing the highest estimates our results further indicate that consumers wtp for green electricity differs by source with hydropower being the least valued variables that are often omitted from primary valuation studies are important in explaining differences in values these variables describe individual and household characteristics as well as information on the type of power plant that will be replaced by renewables further the marginal effect of a survey conducted in the us is pronounced we also assess the potential for using the results for out of sample value transfer and find a median error of 21 c 2015 elsevier b v all rights reserved

the effect of education on adult mortality and health evidence from britain there is a strong positive and well documented correlation between education and health outcomes in this paper we attempt to understand to what extent this relationship is causal our approach exploits two changes to british compulsory schooling laws that generated sharp across cohort differences in educational attainment using regression discontinuity methods we find the reforms did not affect health although the reforms impacted educational attainment and wages our results suggest caution as to the likely health returns to educational interventions focused on increasing educational attainment among those at risk of dropping out of high school a target of recent health policy efforts jel h52 i12 i21 i28

optimal provision of hydroelectric power under environmental and regulatory constraints hydroelectric power plants can quickly and inexpensively respond to changes in electricity demand however this operational flexibility can cause negative environmental im pacts and these environmental effects are miti gated through direct restrictions on hydropower operations rather than taxes or other market based mechanisms a dynamic model of hydro electric generation is used to derive hourly hydro electric generation and purchases of replacement power to meet contract demand in the presence of these operational restrictions the pattern of hydropower generation is shown to depend on differences between on peak and off peak spot electricity prices within the operational restric tions set by external regulatory mechanisms

the intergenerational effects of compulsory schooling this article attempts to improve our understanding of the causal processes that contribute to intergenerational immobility by exploiting historical changes in compulsory schooling laws that affected the educational attainment of parents without affecting their innate abilities or endowments we examine the influence of parental compulsory schooling on children s grade for age using the 1960 1970 and 1980 u s censuses our estimates indicate that a 1 year increase in the education of either parent reduces the probability that a child repeats a grade by between 2 and 4 percentage points

nimby or not exploring the relevance of location and the politics of voiced opinions in renewable energy siting controversies local protests against renewable energy facilities have added fuel to the debate about the so called nimby not in my back yard effect this paper identifies six variables that can hamper the comparison between different public perception studies and offers two broad conclusions on aggregate proximity does have strong influence on public attitudes to proposed projects but the nature strength and spatial scale of this effect may vary according to local context and value of the land residents of stigmatised places are more likely to welcome facilities that are relatively green while people who derive a more positive sense of identity from particular rural landscapes are likely to resist such potential developments especially if they also live there secondly the fear of being branded a nimby and the positive ethics associated with the notion of renewable are both likely to colour the responses of many interviewees these aspects need to be clarified and accounted for in analyses of elicited responses both quantitative and qualitative if we are to improve our understanding of the social construction of individual attitudes in siting conflicts

the relationship between education and adult mortality in the united states prior research has uncovered a large and positive correlation between education and health this paper examines whether education has a causal impact on health i follow synthetic cohorts using successive u s censuses to estimate the impact of educational attainment on mortality rates i use compulsory education laws from 1915 to 1939 as instruments for education the results suggest that education has a causal impact on mortality and that this effect is perhaps larger than has been previously estimated in the literature copyright 2005 wiley blackwell

the accident externality of driving evidence from observance of the jewish sabbath in israel we document and measure an externality of driving whereby a driver s decision to take to the road affects fellow drivers risk of accident because religious jews refrain from driving during the sabbath traffic on israeli roads decreases sharply when the sabbath begins each friday at a precisely defined time before sundown and increases after the sabbath ends on saturday evening at a precisely defined time after sunset using plausibly exogenous variation in traffic volume associated with the sabbath we estimate the effect of traffic volume on the risk of fatal or injurious accident we find that a positive accident externality emerges only at the sabbath exit when traffic volumes are greater remarkably similar results arise when the analysis is confined to non jewish drivers whose travel choices are not bound by the precise timing of the sabbath supporting the interpretation that our findings reflect an externality finally the effect emerges mainly on a class of road sections that is considered highly perilous suggesting that the interaction of traffic volume and road perilousness is important for understanding this issue and shaping implicated policy

does education improve citizenship evidence from the united states and the united kingdom abstract many studies document an association between schooling and civic participation but none credibly investigate causal links we explore the effect of extra schooling induced through compulsory schooling laws on the likelihood of becoming politically involved in the united states and the united kingdom we find that educational attainment is related to several measures of political interest and involvement in both countries we find a strong and robust relationship between education and voting for the united states but not for the united kingdom our us results approach the uk findings when conditioning on registration possibly indicating that registration rules present a barrier to participation

the crime reducing effect of education in this article we study the crime reducing potential of education presenting causal statistical estimates based upon a law that changed the compulsory school leaving age in england and wales we frame the analysis in a regression discontinuity setting and uncover significant decreases in property crime from reductions in the proportion of people with no educational qualifications and increases in the age of leaving school that resulted from the change in the law the findings show that improving education can yield significant social benefits and can be a key policy tool in the drive to reduce crime

valuation of environmental and societal trade offs of renewable energy sources abstract use of renewable energy sources is one solution to decrease green house gas emissions and the use of polluting fossil fuels renewables differ in their environmental and societal impacts and to design sound renewable energy policy societies need to assess the trade offs between alternative sources to enable the evaluation and comparison of renewable energy production alternatives in finland this paper applies the choice experiment to elicit the monetary information on people s preferences for four renewable energy sources wind power hydro power and energy from crops and wood and considers four impacts of energy production effects on biodiversity local jobs carbon emissions and household s electricity bill the nested logit analysis reveals that higher income male gender young age and pro environmental attitude increase the probability to choose renewable energy instead of the current energy mix wind power is on average the most popular renewable energy technology but regional differences exist biodiversity deterioration should be avoided the national aggregate willingness to pay based on stated preferences rather than preferences revealed by actual market behavior for a combination of renewable energy technologies that corresponds to finland s climate change and energy policy is over 500 million euros

do dropouts drop out too soon wealth health and happiness from compulsory schooling abstract this paper uses compulsory schooling laws to evaluate high school dropout decisions the main empirical result is that lifetime wealth increases by about 15 with an extra year of compulsory schooling students compelled to stay in school are also less likely to report being in poor health unemployed and unhappy the main conclusion is that high school aversion alone is unlikely to explain why dropouts forgo substantial gains to lifetime wealth the results are more consistent with the possibility that adolescents ignore or heavily discount future consequences when deciding to drop out of school if teenagers are myopic making school compulsory or offering incentives to stay in school may help improve lifetime outcomes

citizen versus consumer challenges in the uk green power market abstract this paper investigates the potential advantages and disadvantages of green power products as opposed to the traditional fossil fuel levy which was the uk s chosen tax regime as a means of developing renewable energy in the uk willingness to pay for electricity generated from renewables is investigated results indicate that willingness to pay varies with social status and income however results demonstrate that there is a significant minority in full support of some sort of fiscal initiative electricity generated from renewables is a concept supported by the majority however given the stated willingness to pay it is unlikely that any new renewable capacity will result from green tariff schemes in the near term it is concluded that the green citizen must continue to co exist with the green power purchaser if the uk is to make any significant improvement in the contribution of renewable energy to electricity demand the authors would like to acknowledge the support of irene lorenzoni and jane powell of the centre for social and economic research on the global environment university of east anglia leicester energy efficiency advice centre and leicester energy agency

compulsory education and the benefits of schooling causal estimates of the benefits of increased schooling using u s state schooling laws as instruments typically rely on specifications which assume common trends across states in the factors affecting different birth cohorts differential changes across states during this period such as relative school quality improvements suggest that this assumption may fail to hold across a number of outcomes including wages unemployment and divorce we find that statistically significant causal estimates become insignificant and in many instances wrong signed when allowing year of birth effects to vary across regions

can renewable energy be financed with higher electricity prices evidence from a spanish region abstract in this paper we estimate the willingness to pay for mix of renewable sources of electric power by means of a discrete choice experiment survey conducted in spain in 2010 two main categories of power supply attributes are explored source of renewable power wind solar and biomass and the origin of such power the findings suggest that most consumers are not willing to pay a premium for increases in the shares of renewable in their electricity mix for two of the three renewable sources considered wind and biomass an increase of the renewable mix would require a discount instead we record positive willing to pay for increases in the share of both solar power and locally generated power however preferences for types of renewable solar and wind are found to be heterogeneous by classifying respondents in two groups according to the implied importance of the share of renewable sources in their power mix we identify a market segment consisting of 20 of respondents that could promote renewable energy in the absence of subsidies this is because such a segment shows willingness to pay higher than the current feed in tariffs

why the apple doesn t fall far understanding intergenerational transmission of human capital parents with higher education levels have children with higher education levels however is this because parental education actually changes the outcomes of children suggesting an important spillover of education policies or is it merely that more able individuals who have higher education also have more able children this paper proposes to answer this question with a unique dataset from norway using the reform of the education system that was implemented in different municipalities at different times in the 1960s as an instrument for parental education we find little evidence of a causal relationship between parents education and children s education despite significant ols relationships we find 2sls estimates that are consistently lower than the ols estimates with the only statistically significant effect being a positive relationship between mother s education and son s education these findings suggest that the high correlations between parents and children s education are due primarily to family characteristics and inherited ability and not education spillovers

foreign aid and statehood in africa has foreign aid destroyed state institutions in africa african states depend on development assistance to conduct basic government operations yet few of these states are well governed or effective at providing public goods the two trends mounting foreign aid and static or diminishing state performance raise an obvious question is aid dependency contributing to misrule and state failure in africa many critics argue the two phenomena are related i find they are not my analysis fails to show a negative association between aid receipts and two measures of democracy and economic freedom instead the evidence is consistent with a small positive relationship between aid and these indicators of state performance since the international community seems bent on reducing foreign aid an important issue is how african states can maintain and improve their performance with less foreign assistance

natural gas scenarios in the u s power sector abstract the united states power sector is being transformed by the recent rise in the availability and use of unconventional natural gas specifically shale gas that transformation has already produced some of the most significant changes in the operation of the portfolio of electricity generation since wwii further implications are likely to that end we present results from numerical modeling of different united states u s power sector futures these futures assess questions affecting today s natural gas and electric power markets including the impacts of forthcoming epa rules on power plants decarbonization options such as a clean energy standard ces potential improvements in key generation technologies expanded use of natural gas outside of the power generation sector and higher costs for natural gas production assumed to arise from more robust environmental and safety practices in the field the simulations were done using the reeds model looking out to the year 2050 reeds is a capacity expansion model that determines the least cost combination of generation options that fulfill a variety of user defined constraints such as projected load capacity reserve margins emissions limitations and operating lifetimes the baseline scenario shows strong growth in natural gas generation leading to a roughly 2 5 fold increase in gas demand by 2050 many other scenarios also see strong growth in gas fired generation highlighting questions about portfolio diversity climate change and research and development prioritization

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

random preferences towards bioenergy environmental externalities a case study of woody biomass based electricity in the southern united states article i nfo this paper contrasts alternate methodological approaches of investigating public preferences the random parameter logit rpl where tastes and preferences of respondents are assumed to be heterogeneous and the conditional logit cl approach where tastes and preferences remain fixed for individuals we conducted a choice experiment to assess preferences for woody biomass based electricity in arkansas florida and virginia reduction of co2 emissions and improvement of forest habitat by decreasing risk of wildfires and pest outbreaks were presented to respondents as attributes of using green electricity the results indicate that heterogeneous preferences might be a better fit for assessing preferences for green electricity all levels of both attributes were positive contributors to welfare but they were no statistically significant respondents expressed a positive mean marginal willingness to pay wtp for each attribute level the total wtp for green electricity per kilowatt hour was 0 049 kwh or 40 5 per capita year 1 when converted into future total annual expenditures

environmental value transfer state of the art and future prospects abstract the main objectives of the paper are to 1 give an overview of the state of the art of environmental value transfer 2 discuss its prospects and potential role in cba as a decision support tool and 3 provide further guidelines for proper use and application environmental value or benefit transfer is a technique in which the results of studies on monetary environmental valuation are applied to new policy contexts the technique is controversial not least because of academic and political reservations over the usefulness and technical feasibility of economic valuation tools to demonstrate the importance of environmental values in project or programme appraisals testing of environmental value transfer so far has been unable to validate the practice taking into account the conditions set out in the literature for valid and reliable value transfer most transfers appear to result in substantial transfer errors this paper discusses why and addresses the question of which factors may have been overlooked it is argued that the problem is much more fundamental than previously acknowledged strict guidelines in terms of quantitative adjustment mechanisms to valid value transfer are meaningless if the more fundamental issue of differences in the very nature of the values elicited is not addressed at the same time

an options pricing approach to ramping rate restrictions at hydro power plants this paper investigates the impact of ramping rate restrictions imposed on hydro operations to protect aquatic ecosystems the optimal ramping decision is specified as an optimal control problem which results in a hamilton jacobi bellman hjb equation electricity prices are modelled as a regime switching stochastic process the optimal control is determined by solving the hjb equation numerically using a fully implicit finite difference approach with semi lagrangian time stepping the paper focuses on the effect of ramping restrictions on a hydro plant s value and optimal operations and provides an analysis of which factors cause ramping restrictions to have a greater or lesser impact on profitability it is shown that hydro plant value is negatively affected by ramping restrictions but the extent of the impact depends on key parameters which determine the desirability of frequent changes in water release rates interestingly for the case considered value is not sensitive to ramping restrictions over a large range of restrictions the results point to the importance of accurately modelling electricity prices in gauging the trade offs involved in imposing restrictions on hydro operators which may hinder their ability to respond to volatile electricity prices and meet peak demands

economic regulations red tape and bureaucratic corruption in post communist economies summary should state regulatory involvement in the economy necessarily generate corruption while excessive regulatory burden is often treated as a cause of corruption this paper argues otherwise it distinguishes regulatory policy or de jure regulatory regimes from regulatory implementation and offers a more nuanced argument about the relationship between state regulations and bureaucratic corruption the analysis of business survey data covering 25 post communist economies demonstrates that mechanisms of regulatory implementation rather than heavy handed regulatory policy are responsible for bribery this analysis draws attention to the theoretical distinction between different types of regulatory hurdles and their differential effects on the quality of governance

35 years of reforms a panel analysis of the incidence of and employee and employer responses to social security contributions in the uk we exploit variation in national insurance contributions nics the uk s system of social security contributions and a large panel dataset to examine the effects of 35 years of employee and employer nics reforms on labour cost gross earnings plus employer nics hours of work and labour cost per hour both immediately 0 6 months after reforms are implemented and in the slightly longer term 12 18 months we consider assumptions under which the estimated coefficients on net of marginal and net of average tax rates in a panel regression can be interpreted as behavioural elasticities or as reflecting incidence we find a compensated elasticity of taxable earnings with respect to the marginal rate of employee nics of about 0 2 0 3 operating largely through hours of work while that with respect to the marginal rate of employer nics is not statistically significantly different from zero we also find that labour cost falls by a much larger amount when the average rate of employer nics is reduced than when the average rate of employee nics is reduced which is consistent with the economic incidence of nics being strongly affected by its formal legal incidence estimates from the hours and hourly labour cost regressions provide further support to this interpretation of the findings and also suggest the presence of substantial income effects though also after 1999 a puzzling effect of average employer nics rates on hours of work each of these results remains true after 12 18 months if anything coefficients on lagged changes in nics rates strengthen these findings implying that any shifting of employer nics changes to the individual employees concerned and vice versa for employee nics does not begin over this time horizon these results are similar to those found by lehmann et al 2013 for france but represent an extension of that work by considering hours as well as labour cost responses and second year as well as immediate effects

is extending compulsory schooling alone enough to raise earnings evidence from french and british compulsory schooling laws in this paper i compare two reforms that raised the minimum school leaving age to 16 in france 1967 and in england and wales 1972 using a regression discontinuity design i find that while the reform in england and wales led to a 6 7 percent increase in hourly wages per additional year of compulsory schooling the impact of the change to french law was close to zero the results suggest that the major difference between the two reforms was that the fraction of individuals holding no qualifications dropped sharply after the introduction of the new minimum school leaving age in england and wales whereas it remained unchanged in france

selective hedging in hydro based electricity companies abstract we analyze risk management trends in electricity commodity markets using the production and transaction data and written hedging policies of 12 norwegian hydropower companies the scope of our analysis is the hedging of physical electricity production using the power derivatives available at nasdaq omx commodities in their hedging policy these companies either use a cashflow at risk c far approach or a hedge ratio approach or follow no explicitly stated approach we find that the derivative cashflows constitute substantial profits for these companies furthermore hedging contributes to reducing the c far for 10 of the companies these findings are surprising considering that we expect hedging to yield zero expected profit and to smooth the earnings overall our findings reveal that a practice of incorporating market views in hedging decisions is widespread in the sample companies as both sanctioned in their written hedging policy and as indicated by the substantial hedging profits

valuing energy policy attributes for environmental management choice experiment evidence from a research institution abstract many governments firms institutions and individuals have become increasingly cognizant of their impact on the environment most notably with respect to global climate change coupled with the possibility of future regulations aimed at curbing greenhouse gas emissions firms and institutions have begun to critically evaluate their own carbon footprint this paper examines the preferences of stakeholders within a large academic institution for attributes of alternative greenhouse gas ghg reduction strategies the attributes considered by constituents include the fuel portfolio mix effort for conserving energy use carbon emissions reduction timeframe for emissions reduction to be achieved and cost we use a choice experiment technique that enables the examination of greenhouse gas reduction program attribute preferences across three constituent groups the results show that each of the constituent groups have a positive wtp for carbon emissions reductions and prefer investments in reductions in the shorter rather than longer term the results also suggest differences between the constituent groups in their wtp for types of fuels in the fuel portfolio finally we use the results to examine the welfare implications of different combinations of the policy attributes that coincide with alternative ghg program strategies

renewable electricity as a differentiated good the case of the republic of korea this paper examines the willingness for korean consumers to pay a premium for renewable electricity under a differentiated good framework by applying the contingent valuation method korean consumers have been required to pay for their use of renewable electricity as of 2012 first we find that korean consumers recognise renewable electricity as a differentiated good from traditional electricity generated from fossil fuels or nuclear energy the mean willingness to pay to use renewable electricity is usd 1 26 per month second we confirm the existence of perfect substitution relationships among variant renewable technologies which suggests that korean consumers do not perceive them as differentiated goods one reason for this perception is that korean consumers are more inclined to favour economic feasibility over sustainability or the availability of the resource stock when choosing between renewable technology types in sum we can say that korean consumers recognise renewable electricity as a differentiated good but that they do not differentiate between variant renewable technologies thus the imposition of the cost of renewable electricity on consumers in the form of increased electricity charges would be acceptable to consumers as long as any price rise properly reflects their preferences

long run returns to education does schooling lead to an extended old age while there is no doubt that health is strongly correlated with education whether schooling exerts a causal impact on health is not firmly established we exploit a dutch compulsory schooling law to estimate the causal effect of education on mortality the reform provides a powerful instrument significantly raising years of schooling which in turn has a significant and robust negative effect on mortality for men surviving to age 81 an extra year of schooling is estimated to reduce the probability of dying before the age of 89 by almost three percentage points relative to a baseline of 50 percent

zero returns to compulsory schooling in germany evidence and interpretation abstract we estimate the impact of compulsory schooling on earnings using changes in compulsory schooling laws in west germany after world war ii most estimates in the literature indicate returns in the range of 10 to 15 while our research design is very similar to studies for various other countries we find a zero return we find no evidence that this is due to labor market institutions or the apprenticeship training system in germany the result might be due to the fact that the basic skills most relevant for the labor market are learned earlier in germany than in other countries

the effect of education on crime evidence from prison inmates arrests and self reports we estimate the effect of high school graduation on participation in criminal activity accounting for endogeneity of schooling we begin by analyzing the effect of high school graduation on incarceration using census data instrumental variable estimates using changes in state compulsory attendance laws as an instrument for high school graduation uncover a significant reduction in incarceration for both blacks and whites when estimating the impact of high school graduation only ols and iv estimators estimate different weighted sums of the impact of each schooling progression on the probability of incarceration we clarify the relationship between ols and iv estimates and show that the weights placed on the impact of each schooling progression can explain differences in the estimates overall the estimates suggest that completing high school reduces the probability of incarceration by about 76 percentage points for whites and 3 4 percentage points for blacks we corroborate these findings using fbi data on arrests that distinguish among different types of crimes the biggest impacts of graduation are associated with murder assault and motor vehicle theft we also examine the effect of drop out on self reported crime in the nlsy and find that our estimates for imprisonment and arrest are caused by changes in criminal behavior and not educational differences in the probability of arrest or incarceration conditional on crime we estimate that the externality of education is about 14 26 of the private return to schooling suggesting that a significant part of the social return to education comes in the form of externalities from crime reduction

the expansion and convergence of compulsory schooling in western europe 1950 2000 this paper examines the expansion of compulsory schooling in fifteen western european countries over 1950 2000 we show that a convergence process has occurred across these countries since 1950 we argue that the major driver of this phenomenon is the existence of decreasing aggregate returns to education that have limited the extension of compulsory schooling then we test whether convergence holds when confronted with other explanations described in the literature conditional convergence does hold and we find that openness has been another significant determinant of compulsory years of schooling reflecting the need of a skilled labour force in an increasingly globalized world

balancing environmental protection and energy production in the federal hydropower licensing process the u s federal energy regulatory commission ferc must balance environmental protection of riverine resources with the nation s growing demand for power production every time it issues a hydroelectric license this paper models the bureaucratic agency s decision making process in issuing these licenses data on nearly 500 hydro power licenses issued from 1983 to 2005 are utilized it is discovered that legislative and institutional constraints are by far the largest influences on ferc s regulatory decisions implying that if the current allocation of surface water in the united states is considered inefficient the most effective way to alter this allocation is by passing new legislation or by implementing institutional reform at ferc

wish you were here quasi experimental evidence on the effect of education on self reported attitude toward immigrants abstract we use european social survey and labour force survey data from 2002 to 2012 to estimate the causal effect of years of education on european natives opinion toward immigration by exploiting the exogenous discontinuity generated by reforms in compulsory education in europe in the 1940s through the 1990s our findings show that higher levels of education lead to a more positive reported attitude toward immigrants we also investigate the mechanisms behind the effect of education on reported attitudes by evaluating both economic and non economic channels we find that higher levels of education place individuals in occupations that are less exposed to the negative effects of migration although not in sectors occupations where the share of migrants is necessarily smaller suggesting that migrants and low educated natives may be complementary rather than substitutes in the labour market in addition education alters values and the cognitive assessment of the role of immigration in host societies with a positive effect on reported attitude toward diversity and on the assessment of immigration s role in host countries our findings suggest that education as a policy instrument can increase social cohesion in societies that are subject to large immigration flows

life cycle earnings education premiums and internal rates of return using norwegian population panel data with nearly career long earnings histories we provide a detailed picture of the causal relationship between schooling and earnings over the life cycle to address selection bias we apply three commonly used identification strategies we find that additional schooling gives higher lifetime earnings and a steeper age earnings profile in line with predictions from human capital theory our preferred estimates imply an internal rate of return of around 11 suggesting that it was highly profitable to acquire additional schooling our analysis reveals that mincer regressions dramatically understate the returns to schooling because key assumptions are violated

on measuring the shadow price of uncommitted fiscal resources in africa abstract underevaluation of the opportunity cost of uncommitted fiscal resources in african countries results in approval of development projects which later collapse when local budget support for operation and maintenance is not forthcoming a cobb douglas production function is presented using as factors a the civil service establishment and b real government expenditure on complementary goods and services assuming tangency in the early 1970s before civil service expansion notwithstanding fiscal stringency led to compression of b plausible parameters yield a current marginal product of b that is twice or more the tangency value implying a shadow price of 2 0 for uncommitted fiscal resources

educational reform ability and family background in this paper we evaluate the impact of a major school reform that took place in the 1950s in sweden on educational attainment and earnings the reform which has many common elements with reforms in other european countries including the uk consisted of increasing compulsor schooling imposing a national curriculum and abolishing selection by ability into academic and non academic streams at the age of 12 comprehensive school reform our data combines survey data with administrative sources we find that the reform increased both the educational attainment and the earnings of children whose fathers had just compulsory education however the earnings of those with educated parents declined possibly because of a dilution of quality at the top end of the education levels the overall effect of the reform was however positive

whatever the customer wants the customer gets exploring the gap between consumer preferences and default electricity products in germany abstract in liberalized electricity markets residential customers can choose their preferred provider and select among a variety of different electricity products including green power options successful product design and marketing strategies for green electricity may provide electricity providers with a competitive advantage while at the same time contributing to energy policy objectives this requires however a thorough understanding of customer preferences we investigate the relative importance of different product attributes in creating customer value and find that price and electricity mix are the two most important attributes the german electricity customers we surveyed in 2009 expressed an implicit willingness to pay a premium of about 16 for electricity from renewable sources we conclude that consumers are willing to pay a significant price premium for an upgrade from the current default electricity mix in germany to a more environmentally friendly default electricity mix and discuss implications for marketing strategy and energy policy our findings are based on a dataset of 4968 experimental choices made by 414 german residential consumers collected in a stated preference survey

willingness to pay for green electricity in korea a contingent valuation study abstract green electricity is energy that is generated from renewable energy sources such as solar power wind power small scale hydroelectric power tidal power and biomass power these sources mostly do not produce pollutants and are considered environmentally friendly however considering the current state of technology they are more costly government should take visible actions to compensate for the increased production costs this paper attempts to apply a contingent valuation cv method to obtain at least a preliminary evaluation of the benefits that ensue from the introduction of the policy that raises the percentage of green electricity consumption from 0 2 of the total electricity supply to 7 by 2011 overall the cv survey was successful in eliciting the willingness to pay wtp for green electricity considering that the cv method operated within respondents abilities to answer and the wtp estimates were statistically significant the monthly mean wtp estimates from parametric and non parametric methods were krw 1681 usd 1 8 and krw 2072 usd 2 2 respectively the estimates of the annual benefits to relevant residents amounted to krw 150 5 billion usd 157 5 million and krw 185 6 billion usd 194 2 million respectively

bayesian fuzzy regression discontinuity analysis and returns to compulsory schooling summary this paper is concerned with the use of a bayesian approach to fuzzy regression discontinuity rd designs for understanding the returns to education the discussion is motivated by the change in government policy in the uk in april of 1947 when the minimum school leaving age was raised from 14 to 15 a change that had a discontinuous impact on the probability of leaving school at age 14 for cohorts who turned 14 around the time of the policy change we develop a bayesian fuzzy rd framework that allows us to take advantage of this discontinuity to calculate the effect of an additional year of education on subsequent log earnings for the latent class of subjects that complied with the policy change we illustrate this approach with a new dataset composed from the uk general household surveys copyright 2015 john wiley sons ltd

the raising of the school leaving age returns in later life using the recently released uk household longitudinal study we examine whether the raising of the school leaving age in 1972 had a permanent impact on earnings for individuals in their early 50s

books are forever early life conditions education and lifetime earnings in europe we estimate the effect of education on lifetime earnings by distinguishing between individuals who lived in rural or urban areas during childhood and between individuals with access to many or few books at home at age 10 we instrument years of education using compulsory school reforms and find that whereas individuals in rural areas were most affected by the reforms those with many books enjoyed substantially higher returns to their additional education we show that books retain explanatory power even when we select relatively homogeneous groups in terms of the economic position of the household

estimating average and local average treatment effects of education when compulsory schooling laws really matter the change to the minimum school leaving age in the united kingdom from 14 to 15 had a powerful and immediate effect that redirected almost half the population of 14 year olds in the mid twentieth century to stay in school for one more year the magnitude of this impact provides a rare opportunity to a estimate local average treatment effects late of high school that come close to population average treatment effects ate and b estimate returns to education using a regression discontinuity design instead of previous estimates that rely on difference in differences methodology or relatively weak instruments comparing late estimates for the united states and canada where very few students were affected by compulsory school laws to the united kingdom estimates provides a test as to whether instrumental variables iv returns to schooling often exceed ordinary least squares ols because gains are high only for small and peculiar groups among the more general population i find instead that the benefits from compulsory schooling are very large whether these laws have an impact on a majority or minority of those exposed

forced to be rich returns to compulsory schooling in britain do students benefit from compulsory schooling in an important article oreopoulos 2006 studied the 1947 british compulsory schooling law change and found large returns to schooling of about 15 using the general household survey ghs re analysing this dataset we find much smaller returns of about 3 on average with no evidence of any positive return for women and a return for men of 4 7 additionally we utilise the new earnings survey panel data set nespd that has earnings information superior to that in the ghs and find similar estimates zero returns for women and returns of 3 to 4 for men

africa s overgrown state reconsidered bureaucracy and economic growth how close is the link between outsized states and economic stagnation in africa this article shows that african public bureaucracies are not as large as often portrayed that they have been getting smaller and that reducing their size alone has not bee n a prescription for economic revival to the contrary the countries with higher levels of public employment such as botswana and mauritius are apt to have the better economic records these findings suggest that a superabundance of public personnel is not in itself a major impediment to growth in africa too much attention has been paid to quantitative or first generation bureaucratic problems and too little attention has been given the second generation issues of bureaucratic quality
