governmental intervention approaches to promote renewable energies special emphasis on japanese feed in tariff abstract almost all countries have issued laws and regulations to promote renewable energy re however the applications and motivations of such laws as well as achievements have been different currently the japanese government has announced its targets to expand the electricity feed in tariff scheme for solar power along with other energy sources within two years to meet the goal set by the japanese prime minister who in the 15th united nations climate change conference cop15 held in september 2009 proclaimed to cut 25 of greenhouse gas ghg emissions from the 1990 levels by 2020 in this paper the current japanese energy policies and measures for promoting re in comparison to popular methods followed worldwide are explored furthermore a least cost feed in tariff lcfit simulation model for japanese case was developed to calculate the optimal mix of technologies to reach certain targets the lcfit also calculates the tariff that should be proposed for each technology and the total cost for the program with and without a carbon tax and estimates the premium added to the bill of the customer every month

two sample nonparametric estimation of intergenerational income mobility in the united states and sweden we estimate intergenerational income mobility in the us and sweden using a new nonparametric approach the approach addresses several empirical issues raised in the literature and applies when other estimators are infeasible we argue that previous estimates of income mobility conceal the heterogeneous nature of the transmission mechanism by keeping mobility constant across families the striking differences we find between mobility patterns across family backgrounds captured by father s education lead us to question the conventional result that intergenerational transmission of earnings is weaker in sweden than in the united states for important parts of the population

language and the earnings of immigrants several studies most of them employing straightforward regression analysis have concluded that immigrants proficiency in the language of their adopted country is correlated with their productivity as measured by earnings two weaknesses of these studies are potential unobserved heterogeneity which could result in over estimated effects if overall ability is linked with language acquisition and potential measurement error in the language proficiency measures which would probably result in under estimation of language effects the present study which uses panel data for a 10 year period in germany yields evidence that the latter bias tends to be much larger than the former implying that language proficiency is far more important than suggested by the existing literature

social class family background and intergenerational mobility abstract this research examines the various approaches taken by economists and sociologists for analyzing intergenerational mobility social mobility models based on social classes arising from an occupational classification scheme are analysed a test for the statistical validity of classification schemes is proposed and tested using danish sample survey data that was first collected in 1976 and augmented in 2000 this is referred to as a homogeneity test and is a likelihood ratio test of a set of linear restrictions which define social classes for denmark it is shown that this test fails for an erikson goldthorpe classification system raising doubts about the statistical validity of occupational classification systems in general we also estimate regression models of occupational earnings household earnings and educational attainment using family background variables as covariates controlling for unobservables measurement error and simultaneous equation bias in these models homogeneity tests are also rejected we conclude from these results that the individual s family background has a small but significant impact on lifetime chances which is not captured by the erikson goldthorpe classification scheme

electricity supply security and the future role of renewable energy sources in brazil abstract hydropower is the backbone of the brazilian electricity generation sector even though the use of this resource is advantaged in terms of greenhouse gas emissions last years severe droughts have exposed the country s huge dependency on hydroelectricity brazil s electricity supply system has shown to be vulnerable to electricity shortages and has demanded significant overhaul in order to address its challenges the present paper provides a comprehensive review of the current status of the brazilian electricity sector and discusses diversification of electricity generation mix as a strategy to improve electricity supply security in the country an overview of the main features of the energy sources applied in brazil is also presented through a review of the latest available generation data the central section of this work is a discussion of the main causes of the current crisis and the future role of renewable energy sources in a 10 year perspective

intergenerational economic mobility in the united states 1940 to 2000 we estimate trends in intergenerational economic mobility by matching men in the census to synthetic parents in the prior generation we find that mobility increased from 1950 to 1980 but has declined sharply since 1980 while our estimator places greater weight on location effects than the standard intergenerational coefficient the size of the bias appears to be small our preferred results suggest that earnings are regressing to the mean more slowly now than at any time since world war ii causing economic differences between families to become more persistent however current rates of positional mobility appear historically normal

early decision and financial aid competition among need blind colleges and universities abstract this paper presents a stylized theoretical model of competition among need blind colleges and universities that implement early decision admissions under need blind admissions an applicant s financial aid status cannot affect their likelihood of admission in the model a need blind school can use early decision admissions as a screening mechanism to indirectly identify a student s ability to pay while superficially maintaining a need blind policy as a result in equilibrium non financial aid students are more likely to be admitted than financial aid students of comparable quality

correlations of brothers earnings and intergenerational transmission correlations between parent and child earnings reflect intergenerational mobility and more broadly correlations between siblings earnings reflect shared community and family background these earnings relationships capture important aspects of relations in socioeconomic status more generally we estimate intergenerational transmission and sibling correlations of life cycle earnings jointly within a unified framework that nests previous models using data on the danish population of father first son second son triads we find that intergenerational effects account for on average 72 percent of sibling correlations this share is higher than all previous studies because we allow for heterogeneous intergenerational transmission between families sibling correlations exhibit a u shape over the working life consistent with differences in human capital investments between families

intergenerational linkages in consumption behavior consumption is partly a social activity yet most studies of consumer behavior treat households in isolation we investigate familial relationships in consumption patterns using a sample of parents and their children from the panel study of income dynamics we nd a positive and statistically signi cant parent speci c eect on children s consumption even after controlling for the eect of parental income and we nd similar eects for sibling pairs child consumption responds negatively to large post retirement shortfalls in consumption of the parents this behavior holds up even after allowing for the possibility of smaller parent to child transfers made necessary by the parental consumption shortfalls these results suggest that although income is an important source of the intergenerational correlation parental choices and experiences also aect consumption behavior of the children

an alternative measure of intergenerational income mobility based on a random coefficient model summary we propose an alternative measure of the degree to which income status is transmitted from one generation to another our indicator of intergenerational income mobility is based on a random coefficient model which allows for variation in intergenerational mobility across families due to multiplicative unobserved family specific characteristics this alternative measure suggests that intergenerational income persistence is typically stronger than when intergenerational income mobility is measured using the standard elasticity of sons income with respect to fathers income copyright 2011 john wiley sons ltd

a real options valuation of chinese wind energy technologies for power generation do benefits from the feed in tariffs outweigh costs abstract in order to assess the viability of wind energy projects in china this paper takes a real options approach by accounting for flexibility over deployment of the technology in response to a stochastic non renewable energy cost the difference between the latter and the r d enhanced cost of renewable energy operation may be thought of as a benefit from using wind on the other hand the chinese government provides feed in tariffs to encourage further adoption of wind which should be included as a cost this work thus shows that there is substantial options value to china s wind energy program which is bolstered if the cost of carbon dioxide emissions is internalized moreover by varying the rate of feed in tariffs the model may be used to show plausible ranges for the feed in tariffs which could be a useful policy insight furthermore the study hypothesizes that with the likelihood of renewable energy to replace non renewable energy wind power in china can potentially reduce co2 emissions by approximately 6 4 by 2020 comparing to the 2005 level and highlights the significant role of wind power in china s emission targets and energy security this is a relevant paper especially given the importance of a sustainable energy transition for china more generally using the real options approach from a policy perspective could provide insights about the viability of renewable energy programs and robustness of feed in tariffs rates

allocation of firm energy rights among hydro plants an aumann shapley approach the firm energy of generation plants is a critical component in some electricity markets it is usually calculated by the regulator and sets a cap to the amount a plant can trade in capacity markets or auctions in order to avoid free riding behaviors firm energy is a systemic property and in case of hydro plants a synergy is observed whenever a cooperative operation occurs i e the firm energy of a system is greater than the sum of the individual plants this immediately raises the question of how to divide the system s firm energy among the individual hydro plants the objective of this work is to investigate the application of different allocation methods of firm energy rights among hydro plants using a game theoretic framework it is shown that there is not an optimal and unique approach to make this allocation the paper investigates the advantages and disadvantages of different methods such as marginal allocation average production during the critical period incremental allocation finally recommending the aumann shapley as the allocation method this method is tested for the brazilian power system which has around 100 hydro plants the results obtained are compared with the current allocation adopted by the electricity regulatory agency of brazil

slipping into and out of poverty the dynamics of spells this paper examines the dynamics of poverty previous analyses have examined either fluctuations in the male heads earnings or the frequency of poverty periods over a fixed time frame our approach depends on a definition of spells of poverty using this methodology we find that the majority of poor persons at any time are in the midst of a rather long spell of poverty the methodology also allows us to estimate that less than 40 percent of poverty spells begin because of a drop in the heads earnings while 60 percent of the spells end when the heads earnings increase thus researchers must focus on household formation decisions and on the behavior of secondary family members there has been a dramatic resurgence recently of discussion of the underclass the discussion is reminiscent of debates about poverty during the 1960s when the notions of a culture of poverty particularly as popularized by michael harrington s other america 1962 dominated both intellectual and policy thinking the idea of an underclass seems inconsistent however with much of the research on the dynamics of poverty during the 1970s that research using new longitudinal data seemed to show that the bulk of the poor were poor for only a few years the research also showed that the poor were a very heterogeneous group including a small minority of persistently poor the persistence of poverty is of interest both for understanding the phenomenon and for developing policy claims about dependency and separate life styles among the poor rest on assumptions about the long term nature of poverty questions

trends in intergenerational income mobility previous studies of recent u s trends in intergenerational income mobility have produced widely varying results partly because of large sampling errors by making more efficient use of the available information in the panel study of income dynamics we generate more reliable estimates of the recent time series variation in intergenerational mobility our results which pertain to the cohorts born between 1952 and 1975 do not reveal major changes in intergenerational mobility

the determinants of earnings a behavioral approach we survey the determinants of earnings and propose a framework for understanding labor market success we suggest that the advantages of the children of successful parents go considerably beyond the benefits of superior education the inheritance of wealth or the genetic inheritance of cognitive ability we suggest that noncognitive personality variables such as attitudes towards risk ability to adapt to new economic conditions hard work and the rate of time preference affect both earning and the transmission of economic status across generations

centralization fiscal federalism and private school attendance a cge model is used to analyze the impact of public school financing on private school attendance the common perception that public school finance centralization will necessarily lead to greater private school attendance is not correct in such a model even when that centralization involves an extreme equalization as in california furthermore if centralization is less dramatic as in most states declines in private school attendance are even more pronounced this weakens the speculation that low exit rates to private schools in centralizing states imply that general public school quality does not drop as a result of such centralization

development of the wind power in brazil political social and technical issues abstract this paper aims to present a review of the increasing contribution of wind power to the brazilian electric matrix and an analysis of the main impact on technical political and social aspects this work takes into account the state of art of the wind power technology the wind resource potential and the evolution of installed capacity in the country the institutional programs and the fiscal incentives provided by the brazilian government are also discussed in this paper including its impacts on the society we have reviewed national and international reports and relevant scientific papers to realize this work the analysis shows that electric crisis in 2001 led the brazilian government to develop new energy policies that supported the rapid growth of the wind industry from imported technology later on in the year 2004 the government mandated that the technology be developed within the country it is expected that from 2011 of approximately 1500 mw until 2021 the installed wind capacity would increase by a factor of 600 however the national technology acquisition and development is still incipient it is important to produce locally wind turbine components and is highly desirable to increase collaboration between industries and universities in the country

photovoltaic electricity production in brazil a stochastic economic viability analysis for small systems in the face of net metering and tax incentives abstract currently in addition to the search for sustainable development there is increased pressure for a change in consumption and production of energy patterns in brazil in this scenario net metering is an important mechanism fostering dissemination of small photovoltaic pv solar systems as complementary support to net metering a tax exemption is currently being offered in some brazilian states thus the objective of the present study is to analyze the impact of tax exemption on the circulation of goods and services and the returns and risks of the pv microgeneration project in four cities located in different regions of brazil belem petrolina uberaba and uruguaiana the analysis is performed using the monte carlo simulation mcs wherein uncertainties related to the financial and environmental variables are considered the results of the stochastic economic viability analysis allowed us to conclude that the exemption of tax on circulation of goods and services icms is fundamental to make pv microgeneration viable in brazil in the cities analyzed pv microgeneration presented economic unfeasibility to the investor when the icms is charged when considering the icms exemption policy the cities of petrolina and belem obtained high probabilities of viability in relation to the risk analysis pv microgeneration obtained the best results in petrolina both in terms of the condition of collection and exemption of icms there is high potential for harness solar throughout the brazilian territory however due to the current evolution stage and the productive chain of the brazilian pv industry high costs limit the expansion of this clean energy generation technology the findings of this study could assist policymakers in evaluating this incentive program highlighting that this tax exemption directly meets one of the objectives for which the icms was created which is to encourage the development of productive sectors such as pv industry

biases in standard measures of intergenerational income dependence abstract estimates of the most common mobility measure the intergenerational elasticity can be severely biased if snapshots are used to approximate lifetime income however little is known about biases in other popular dependence measures using long swedish income series we provide such evidence for log linear and rank correlations and rank based transition probabilities attenuation bias is considerably weaker in rank based measures life cycle bias is strongest in the elasticity moderate in log linear correlations and small in rank based measures however there are important exceptions persistence in the tails of the distribution is considerably higher and long distance downward mobility lower than estimates from short run income suggest

electricity auctions in south america towards convergence of system adequacy and res e support regulatory reforms of the electricity industry in south america have always been prompted by the need of attracting enough investment to cover the fast paced demand growth in order to achieve this goal the countries in the region which in the eighties and early nineties opted for market oriented schemes have rebuilt in the last decade their regulatory frameworks around long term auctioning these new mechanisms initially implemented to attract investment in any sort of conventional generation technology so as to ensure the system adequacy are increasingly being also used to bring in non conventional renewable energy resources these schemes have been until now run in parallel but the steep learning curve of renewable energy sources for electricity res e technologies is apparently opening the door to the implementation of new tendering procedures open to all kinds of generation technologies in this article we review the auction mechanisms for new generation implemented in south america we argue that although the first impression might lead to the conclusion that conventional and res e technologies are in some cases close and even ostensibly competing in the same auctions the fact is that the full convergence is still far to happen as the rules and products applied to the different technologies differ significantly

nonlinearities in intergenerational earnings mobility consequences for cross country comparisons we show that the patterns of intergenerational earnings mobility in denmark finland and norway unlike those for the us and the uk are highly nonlinear the nordic relationship between log earnings of sons and fathers is flat in the lower segments of the fathers earnings distribution sons growing up in the poorest households have the same adult earnings prospects as sons in moderately poor households and is increasingly positive in middle and upper segments this convex pattern contrasts sharply with our findings for the us and the uk where the relationship is much closer to being linear as a result cross country comparisons of intergenerational earnings elasticities may be misleading with respect to transmission mechanisms in the central parts of the earnings distribution and uninformative in the tails of the distribution it is now a stylised fact that intergenerational earnings mobility is higher in the nordic welfare state economies than in more market oriented economies such as the us see

pay as you go social security and the distribution of altruistic transfers this paper studies the impact of an unfunded social security system on the distribution of altruistic transfers in a framework where savings are due to both life cycle and random altruistic motivations we show that the effect of social security on the distribution of these transfers depends crucially on the strength of the bequest motive in explaining savings behaviour we measure this strength by the expected weight that individuals attach to the utility of future generations on the one hand if the bequest motive is strong then an increase in the social security tax raises the bequests left by altruistic parents on the other hand when the importance of altruism in motivating savings is sufficiently low the increase in the social security tax could result in a reduction of the bequests left by altruistic parents under some conditions on the attitude of individuals toward risk and on the relative returns associated with private saving and social security some implications concerning the transitional effects of introducing an unfunded social security scheme are also discussed

does education expansion increase intergenerational mobility education expansion may lead to over education where the social connections of parents may exert more significant influence on the return to education of children with the assumption of a positive correlation between return on human capital and parental income in the presence of over education we show that i the expansion of education may cause horizontal inequity in education opportunities and inefficiency in human capital accumulation ii the positive correlation between return on human capital and parental income causes a more persistent intergenerational immobility iii an expansion of education especially higher education leads to more persistent intergenerational immobility

the intergenerational persistence of lifetime earnings abstract this paper proposes a new method for estimating the intergenerational persistence of lifetime earnings from data that contain only short sections of individual earnings histories the approach infers lifetime earnings persistence from the persistence of short earnings averages together with information about the stochastic process governing individual earnings i find that lifetime earnings are substantially more persistent than previous estimates based on short panel data suggest about 54 of lifetime earnings differences between fathers persist into their sons generation this persistence estimate exceeds previous estimates based on five year earnings averages by one third these findings are robust against alternative assumptions about the data generating process for earnings

regression toward mediocrity in economic stature this paper provides estimates of the correlation in lifetime earnings between fathers and sons intergenerational data from the national longitudinal survey are used earlier studies conducted for the united states report elasticities of children s earnings with respect to parent s earnings of 0 2 or less suggesting extensive integenerational mobility these estimates however are biased downward by error contaminated measures of lifetime economic status estimates presented in this paper correct for the problem of measurement error and find the intergenerational correlation in income to be on the order of 0 4 this suggests considerably less intergenerational mobility than previously believed jel j62

intergenerational income mobility in the united states social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the united states but remarkably little empirical evidence is available the few existing estimates of the intergenerational correlation in income have been biased downward by measurement error unrepresentative samples or both new estimates based on intergenerational data from the panel study of income dynamics imply that the intergenerational correlation in long run income is at least 0 4 indicating dramatically less mobility than suggested by earlier research copyright 1992 by american economic association

the foundations of money illusion in a neoclassical micro monetary model comment 1 that their equation 2 is logically equivalent to our hereafter d k sufficiency conditions presented in the 1974 issue of this review 2 that the assumption of degree zero homogeneity in the variables m and p of the utility function serves completely to characterize the class of illusion free demand functions derivable from ordinal utility theory 3 that it is possible to reinstate the usual slutsky properties by adopting the semi separable utility function given in their equation 4

intergenerational earnings mobility in norway levels and trends using longitudinal data for norwegian children born in 1950 1955 1960 and 1965 we find a relatively high degree of earnings mobility there is no tendency toward decreasing mobility over the cohorts conditioning on the position in the earnings distribution the analysis indicates quite high mobility in the middle of the distribution and somewhat more persistence at the top and bottom this approach also reveals increased mobility over time for sons but a less clear picture for daughters

educational vouchers and cream skimming educational vouchers and cream skimming epple and romano 1998 show equilibrium provision of education by public and private schools has the latter skim off the wealthiest and most able students and universal vouchers lead to further cream skimming here we study voucher design that injects private school competition and increases technical efficiencies without cream skimming conditioning vouchers on student ability without restriction on participating schools policies fails to affect significantly cream skimming however by adding restrictions like tuition constraints such vouchers can reap the benefits of school competition without increased stratification this is accomplished while allowing voluntary participation in the voucher system and without tax increases

the political economy of intergenerational income mobility the intergenerational elasticity of income is considered one of the best measures of the degree to which a society gives equal opportunity to its members while much research has been devoted to measuring this reduced form parameter less is known about its underlying structural determinants using a model with exogenous talent endowments endogenous parental investment in children and endogenous redistributive institutions we identify the structural parameters that govern the intergenerational elasticity of income the model clarifies how the interaction between private and collective decisions determines the equilibrium level of social mobility two societies with similar economic and biological fundamentals may have vastly different degrees of intergenerational mobility depending on their political institutions we offer empirical evidence in line with the predictions of the model we conclude that international comparisons of intergenerational elasticity of income are not particularly informative about fairness without taking into account differences in politico economic institutions jel e24 j62 j68 p16

economic interpretations of intergenerational correlations science itself for example see galton s 1869 study of the eminence of relatives or his 1889 analysis of the heights of parents and children but extensive use of economic theory to interpret these correlations is much more recent using basic economic concepts such as supply demand investment incentives missing markets and so on theorists hope to explain how and why status is correlated across generations economic theory might provide a unified treatment of a variety of socioeconomic indicators such as earnings income occupation or wealth or it might predict how taxes subsidies and economic regulation affect intergenerational mobility and the operation of markets however while the subject matter earnings consumption wealth occupa tion is clearly interesting to economists it could nonetheless be the case that beyond basic questions of measurement economic theory has not improved our understanding of intergenerational mobility goldberger 1989 is quite explicit in this contention by emphasizing the distinction between genes and environment and by using statistical theory as its main analytical tool the paper by samuel bowles and herbert gintis in this issue implicitly concurs with goldberger we take this challenge very seriously what characterizes an economic approach to mobility while biologists and bowles and gintis distinguish endowments and investments by their source genetic versus environmental factors one focus of economic theorists is motiva

the evaluation of feed in tariff regulation of turkey for onshore wind energy based on the economic analysis abstract renewable energy sources have become popular with the technological developments the increase in the price of fossil fuels and the environmental concerns these factors have also prompted turkey to utilize her rich renewable energy sources to meet her increasing electricity demand which is around 7 annually therefore the renewable energy law was enacted in 2005 to incentivize the utilization of domestic renewable sources with feed in tariffs in this study onshore wind energy potential of turkey is analyzed to find out whether these regulations and incentives will help the utilization of onshore wind energy potential to that end some background information about technology and cost of onshore wind power plants the wind energy potential of turkey and the current regulatory framework related to wind energy are explained then a model is set up to conduct economic analysis by calculating npv for the base case scenario and under the uncertain environment the results show that an onshore wind energy potential of about 13 gw having a wind speed of 7 5 m s or higher can be utilized profitably with the current feed in tariff as the wind capacity of more than 100 gw cannot be utilized economically

fortunate sons new estimates of intergenerational mobility in the united states using social security earnings data previous studies relying on short term averages of fathers earnings have estimated the intergenerational elasticity ige in earnings to be approximately 0 4 due to persistent transitory fluctuations these estimates have been biased down by approximately 30 or more using administrative data containing the earnings histories of parents and children the ige is estimated to be around 0 6 this suggests that the united states is substantially less mobile than previous research indicated estimates of intergenerational mobility are significantly lower for families with little or no wealth offering empirical support for theoretical models that predict differences due to borrowing constraints

economic and mechanical models of intergenerational transmission the author critically examines gary beckers attempt to integrate the theory of income distribution intragenerational differences with the theory of mobility intergenerational differences in an economic model of the family he assesses beckers claims of distinctiveness integration explanatory power and surprise and arrives at a rather skeptical view of the contribution that the core of microeconomics has made to this study of the family a reply by becker is included pp 514 8 excerpt

the role of the urban non urban cost of living difference in measured intergenerational earnings mobility abstract in light of a substantial compensating urban non urban wage gap a documented strong intergenerational persistence of urbanicity could produce a higher intergenerational association in nominal than in real earnings controlling interarea cost of living differences i find that the estimated elasticity for real earnings is less to a statistically significant degree

wind energy in brazil from the power sector s expansion crisis model to the favorable environment since the 1970s demands arising from the impacts of the power sector on the natural environment were added to studies regarding the strategic power sector and its impact on the economic and financial crises thus the development of alternative technologies reflected the new institutional guidelines and overcame the technological paradigms that were based on increasing installed capacities consequently multiple debates that consider the energy use potential of each region and its contributions to sustainable development occurred this paper presents the information that is necessary for understanding the relationships of the development model that was founded based on waste and the expanding technologies that exploit natural resources actions that are aimed at developing renewable energy resources are structured based on the instability of the technological maintenance paradigm and are guaranteed by expanding technologies that were used prior to 1970 in addition we evaluated the current institutional arrangements that are used to promote wind energy in this case greater attention was given to the european experience because europe provides multiple examples of successful legal frameworks that promote wind energy in addition europe is a benchmark for emerging market countries such as brazil

how important is human capital a quantitative theory assessment of world income inequality we develop a quantitative theory of human capital investment in order to evaluate the magnitude of cross country dierences in total factor productivity tfp that explains the variation in per capita incomes across countries we build a heterogeneousagent economy with cross sectional variation in ability schooling and expenditures on schooling quality in our theory the parameters governing human capital production and random ability process have important implications for a set of cross sectional statistics mincer return variance of earnings variance of schooling and intergenerational correlation of earnings these restrictions of the theory and u s household data are used to pin down the key parameters driving the quantitative implications of the theory our main finding is that human capital accumulation strongly amplifies tfp dierences across countries in particular we find an elasticity of output per worker with respect to tfp of 2 8 a 3 fold dierence in tfp explains a 20 fold dierence in output per worker we argue that the cross country dierences in human capital implied by the theory are consistent with a wide array of evidence including earnings of immigrants in the united states average mincer returns across countries and the relationship between average years of schooling and per capita income across countries the theory implies that using mincer returns to measure human capital understates dierences across countries by a factor of 2

economic growth under money illusion abstract empirical and experimental evidence documents that money illusion is persistent and widespread this paper incorporates money illusion into a stochastic continuous time monetary model of endogenous growth we model an agent s money illusion behavior by assuming that he maximizes nonstandard utility derived from both nominal and real quantities money illusion affects an agent s perception of the growth and riskiness of real wealth and distorts his consumption savings decisions it influences long run growth via this channel we show that the welfare cost of money illusion is negligible whereas its impact on long run growth is noticeable even if the degree of money illusion is low

the influence of socioeconomic background on the earnings of young men using the panel study of income dynamics we test the proposition that interaction between education and socioeconomic status ses has a negative impact on earnings contrary to findings by papanicolaou and psacharopoulos for the united kingdom no

evaluation of the environmental economic and social performance of soybean farming systems in southern brazil soybean production has a crucial role in the development of brazilian agriculture and recently became the most important commodity in brazilian agribusiness various soybean farming systems exist which are claimed to differ in terms of sustainability performance in this regard evaluation of environmental economic and social performance of different soybean farming systems in brazil by consideration of variability in input parameters is critically needed in this context we evaluated a number of environmental economic and social issues for the two main soybean farming systems in southern brazil the conventional system which produces genetically modified gm or non genetically modified non gm soybeans and the organic system data were collected for 2012 from three sources soybean farms in parana brazil 15 gm 15 non gm and 15 organic farms the brazilian enterprise for agricultural research embrapa and expert elicitation monte carlo simulation was used to account for the variation in input parameters five sustainability issues were evaluated in this study global warming land occupation primary energy use profitability and employment results revealed that compared with the gm and non gm systems organic systems had a higher probability 77 to have a lower global warming potential land occupation was higher and energy use was lower for organic systems than for the gm and non gm systems at every level of probability concerning profitability organic systems had a higher probability 60 to have higher profitability compared with gm and non gm production and employment was higher for organic systems at every level of probability overall simulation results of this study illustrated the relatively high level of variation in the environmental economic and social performance of organic soybean farming systems this study shows that accounting for variability in key system parameters provides not only insight in the most likely outcomes but also in the robustness of system performance

intergenerational persistence of earnings the role of early and college education recent empirical evidence from the united states indicates a high degree of persistence in earnings across generations designing effective public policies to increase social mobility requires identifying and measuring the major sources of persistence and inequality in earnings we provide a quantitative model of intergenerational human capital transmission that focuses on three sources innate ability early education and college education we find that approximately one half of the intergenerational correlation in earnings is accounted for by parental investment in education in particular early education we show that these results have important implications for education policy

family economics and macro behavior in this 1987 presidential address to the american economic association the author explores the contributions of the field of family economics to macroeconomic analysis the focus is on family behavior as an active endogenous factor that both affects and is affected by the evolution of the economy much of the time is spent on long term economic growth although i also discuss short and long cycles in economic activity and the interaction between overlapping generations through social security transmission of inequality and in other ways many conclusions in these and presumably other macro areas change radically when family choices get the attention they deserve excerpt

parental wealth and adult children s welfare in marriage abstract many studies find that parental resources importantly determine children s human capital schooling returns and earnings the collective household approach suggests that in addition parental resources of marital partners may importantly affect resource distributions within marriage this paper presents empirical results consistent with this framework they suggest that parental wealth continues to play roles in augmenting welfare of children into adulthood beyond provision of human capital in early life cycle stages or direct financial aid during adulthood and that actual transfers from parents to adult children do not fully measure influences of parental wealth on behaviors and welfare of adult children

unobservable family and individual contributions to the distributions of income and wealth this paper uses combinations of full brothers half brothers and fathers and sons to measure the effect of common family background on a household s income and wealth while the data are drawn from a nineteenth century population the intraclass correlation for income ranges from 13 to 18 which is similar to that found in modern samples intraclass correlations for wealth are significantly higher 18 35 than are those for income intraclass correlations of half brothers compared to those for full brothers suggest that fathers play a dominant role in the transmission of the common family effect when unobserved background is decomposed into individual and family effects the individual effect dominates the family effect for income while the family effect dominates the individual effect for wealth

voting education and the great gatsby curve abstract high inequality goes hand in hand with low intergenerational earnings mobility across countries little is known about why the us is characterized by high inequality and low mobility while the opposite tends to hold for scandinavian countries in an overlapping generations model calibrated to the us education policies are endogenized via probabilistic voting by exploiting cross country variation in the bias in voter turnout towards the educated and elderly the model replicates the negative relation between inequality and public education expenditures and accounts for more than a quarter of the variation in inequality and mobility for the us i find that compulsory voting could foster mobility whereas inequality would be hardly affected

another problem in the estimation of intergenerational income mobility abstract the current econometric model of intergenerational income mobility is premised on a simplified notion of permanent income analytical results and empirical evidence suggest that estimates are not robust to failure of this assumption

more equal but less mobile education financing and intergenerational mobility in italy and in the us a centralised and egalitarian school system reduces the cost of education for poor families and so it should reduce income inequality and make intergenerational mobility easier in this paper we provide evidence that italy compared to the usa displays less income inequality as expected given the type of school system but also less intergenera tional upward mobility between occupations and between education levels we explore some of the reasons which can explain this puzzling result and conclude that in a world in which family background is important for labor market success a centralised and egalitarian tertiary education does not necessarily help poor children and may take away from them a fundamental tool to prove their talent and to compete with rich children 1999 elsevier science s a all rights reserved

earnings mobility in times of growth and decline argentina from 1996 to 2003 summary in recent years argentina s economy has experienced both rapid growth and severe decline in this paper we use a series of one year long panels to study who gained the most in pesos when the economy grew and who lost the most in pesos when the economy contracted various considerations led us to expect that mobility would be divergent that is that the individuals who started with the highest initial earnings would enjoy the largest earnings gains in pesos contrary to expectations and for a wide range of specifications mobility is found to be mostly convergent sometimes neutral and never divergent

classification of wind use level and required investment for countries below average to upgrade abstract wind energy development is unbalanced over the world and it is urgent to make a promotion for countries with lower wind utility to overcome the issues of increasing demand of energy generation and reduction of greenhouse gas emission two indicators the wind energy exploitation rate and the growing trend are defined to represent onshore wind use level by country the wind energy exploitation rate er is the ratio of current installed capacity to technical potential and growing trend tr is the linear slope of installed capacity depended on gdp per capita non linear functions are used to fit the average curve of er and tr and divide them to 5 and 3 grades according to these classifications we calculate the new installed capacity and associated investment for countries that are now in lower er grade to reach the world average level in 2030 three main conclusions are drawn from the results 1 africa is the poorest wind power developed region over the world where 34 countries still not utilize their wind power europe is the best wind power developed region where 60 of the countries are in high to very high er grades polarization is found in asia and central america and the caribbean where there are many countries with higher and lower er while few in normal level 2 the total new installed onshore wind capacity and the associated investment are 1626 7 1448 0 1828 5 gw and 3257 2 2899 9 3661 4 billion usd for 90 countries with er now in low to zero grades to reach the world average level in 2030 in which 80 non annex i countries account for 339 2 301 2 383 4 gw and 754 3 669 8 852 2 billion usd it could help evaluate whether a country s wind investment plan is sufficient to catch up with the world average level 3 most countries in middle east africa and asia need to increase investment to keep their er with world average level in which there are 13 non annex i countries in both low tr and low to very low er grades

patterns of intergenerational mobility in income and earnings this paper characterizes the patterns of intergenerational mobility in the united states using data for matched parent child pairs from the national longitudinal surveys in general what is found is far from the extremes of either perfect mobility or perfect immobility parents log income explains only about 9 percent to 11 percent of the variation in children s log incomes earnings exhibit more mobility than does total income and the difference is most striking for daughters the paper also identifies the influence of family background characteristics on mobility the addition of these background variables adds another 3 to 5 percent age points to the r2 in the intergenerational earnings and income regressions copyright 1992 by mit press

can the regulated market help foster a free market for wind energy in brazil abstract wind energy has been negotiated in brazil s regulated market through auctions organized by the government bilateral negotiations in the free market have been scarce in 2011 wind farms were allowed to bid in a minus 5 a 5 auctions for energy with first delivery date 5 years ahead this new design was expected to stimulate negotiations in the free market as the 20 year contract in the regulated market eases financing while the 5 year grace period grants wind farms the option to sell whatever energy is generated beforehand in the free market we modeled bidders price decision in a 5 auctions as real options and concluded that given the low prices averaging usd 50 mw h winners are tempted to defer investment expecting more favorable equipment and energy prices or a better knowledge of the wind site construction is likely to begin in 2 3 years with little time left for the free market bidders that consider the option of eventually abandoning the project are more price competitive increasing chances that some wind farms will never materialize therefore this attempt to foster the free market may not pay off and moreover it may have the unfavorable effect of turning brazil s energy expansion planning a more difficult task

china s strategy for carbon intensity mitigation pledge for 2020 evidence from a threshold cointegration model combined with monte carlo simulation methods abstract this paper specifies a nonlinear threshold cointegration to analyze the nonlinear relationship between carbon intensity and economic growth in china the tests and estimated results clearly confirm that fast paced economic growth that is the growth rate of gross domestic product gdp is greater than 9 053 impede the reduction of carbon intensity because it weakens the negative effects of tertiary industry development and energy efficiency on carbon intensity while it also increases the positive effect of unclean energy mix on carbon intensity in order to find a moderate range of economic growth rate that is both beneficial for industrial structuring and energy mix transformation and at the same time facilitate reduction in carbon intensity monte carlo simulations are employed the results show when the growth rate of gdp is between 7 and 8 4 it can promote structural bonus of industrial structure and energy consumption structure on carbon intensity and carbon intensity in 2020 would decline by about 40 60 compared to 2005 level these conclusions mean it is necessary for china to carefully set its economic growth target through transformation and optimization of its economic structure and energy mix in order to continuously reduce carbon intensity

snapshots versus movies empirical studies of the intergenerational inheritance of economic status should use observations on complete lifetime status profiles of parents and children to be consistent with underlying theory but they cannot only snapshots rather than movies on status are currently available in samples estimates of the degree of intergenerational inheritance may therefore be subject to lifecycle biases the paper investigates these in the context of a lifecycle earnings model and shows that these biases may be large that their direction varies and that correction methods suggested hitherto have questionable reliability until more complete data sets become available researchers should be more temperate in the conclusions they draw

factors affecting the transmission of earnings across generations a quantile regression approach in this paper we estimate intergenerational earnings mobility models using quantile regressions quantile regression is a less restrictive estimation approach than more commonly used methods such as ordinary least squares and instrumental variables which only estimate the mean effects of intergenerational earnings correlation further we investigate the role of education as an intergenerational transmission mechanism for earnings we find that the intergenerational earnings correlation is greater at the bottom of the son s conditional earnings distribution than at the top and that controlling for son s education reduces the intergenerational earnings correlation we also find that education is relatively more valuable at the bottom of the conditional earnings distribution and thus tends to compress the distribution

wind power generation an impact analysis of incentive strategies for cleaner energy provision in brazil brazil has adopted various strategies to encourage alternative renewable energy sources in pursuit of cleaner and sustainable energy production to this end strategies should support the reduction of the financial risk for potential investors in the renewable energy market therefore this study aims to analyze the impact of incentive strategies on the financial risk of wind power generation projects in brazil in different marketing environments from a quantitative approach using monte carlo simulation in three scenarios we evaluate the impact of funding from the national development bank and participation in the clean development mechanism in the financial returns of the investor in a regulated contracting environment and free contracting environment measured by the net present value we conduct a statistical analysis to find out if there were statistically significant differences in investor risk in each scenario the main results of the study are as follows the wind speed the selling price of energy and disbursement for the investment have the most significant impact on the financial return the project viability probability is greater than 85 in all scenarios regardless of the marketing environment the regulated market is less risky for the producer than the free market since there is a statistically significant difference in net present value variances for all scenarios in the regulated contracting environment funding is critical to reducing risk and carbon credit trading is not a suitable policy for providing financial security to renewable energy producers thus we conclude that in brazil the contracting of projects from auctions in the regulated contracting environment with the support of the national development bank has been important for neutralizing the producer s financial risks

house price growth when children are teenagers a path to higher earnings abstract this paper examines whether rising house prices immediately prior to children entering college have an impact on their earnings as adults higher house prices provide homeowners with additional funding to invest in their children s human capital but also raise housing costs the results show that a 1 percentage point increase in house prices when children are 17 years old results in roughly 0 9 percent higher annual income for the children of homeowners and 1 5 percent lower annual income for the children of renters house price appreciation at age 17 also leads to higher college enrollment rates at age 19 and an increased likelihood of attendance at higher ranked post secondary institutions for children of homeowners as well as lower college enrollment rates for children of renters

long term effects of feed in tariffs and carbon taxes on distribution systems in deregulated electricity sector climates such as in ontario the production of clean or renewable energy by small power producers through distributed generation dg is encouraged this paper examines the policies that can be used to encourage dg investment and incorporates them into a mathematical model this model is then used to create scenarios for examining the economic and environmental supply side effects of policies to a distribution system over a ten year period the policies analyzed include a combination of feed in tariffs co2 tax and cap and trade schemes the results are discussed in the context of the ontario market and its standard offer program implemented on a 32 bus radial distribution system

clean development mechanism cdm after the first commitment period assessment of the world s portfolio and the role of latin america abstract the clean development mechanism cdm represents the main effort to help developing countries develop sustainably and developed countries to reach their emission reductions targets set under the kyoto protocol with the ending of the first commitment period there is an opportunity to assess the state of the cdm portfolio 2008 2012 this article is the first effort to evaluate the cdm portfolio throughout the first commitment period as well as the first paper focused on latin america s cdm portfolio as a whole concentrating on renewable energy projects moreover a special analysis is performed for chile latin america s third most important cdm country after brazil and mexico 6th worldwide after china india korea brazil and mexico and first in cers registered among the small countries an ideal host because of its high political stability government effectiveness access to capital and regulatory quality in addition a study was performed on 180 renewable energy projects in latin america revealing that the additionality assessments performed under the cdm are too subjective hindering the validation of the projects and their transparency the main policy implication of this research is to expose the need for a radical change to the succeeding document to the kyoto protocol in order to reduce the inequality amongst host countries and ensure that cdm fulfills its sustainable development claim some of the proposed measures include establishing uniform benchmarks to be used against similar projects a thorough validation for declared barriers simplifying the registering process and providing international aid for the least developed countries that have historically lacked the ability to participate in the cdm

risk based assessment of the cost efficiency and the effectivity of renewable energy support schemes certificate markets versus feed in tariffs the introduction of renewable energy sources in the electricity generation mix has the potential to reduce power sector s emissions and countries dependence on imported oil climate change concerns and highly volatile oil prices have attracted governments interest and support to sustain investments in renewable energy capacity and different support policies have been implemented in many countries around the world this paper analyzes the effects of investors risk aversion on the performance of support schemes the analysis compares two policy options a feed in tariff mechanism with a certificate market system results show that while a tariff mechanism could obtain better results than a certificate market its performance is strictly dependent on regulator choices a certificate market instead permits to obtain the desired level of renewable energy market share with good cost efficiency as long as investors risk aversion is moderate moreover discounting future cash flows with higher social discount rates further benefits a certificate system making it preferable to feed in tariffs

the inheritance of inequality how level is the intergenerational playing field what are the causal mechanisms that underlie the intergenerational transmission of economic status are these mechanisms amenable to public policies in a way that would make the attainment of economic success more fair these are the questions we will try to answer

examining the financial performance of micro generation wind projects and the subsidy effect of feed in tariffs for urban locations in the united kingdom abstract this paper seeks to evaluate the effect of the upcoming 2010 uk feed in tariff uk fit on decentralised small wind energy installations at the household and building level in urban locations it is projected that the uk fit will stimulate an unprecedented surge in building mounted turbine installation the tariff amount must stimulate incentive but mitigate the likelihood of distortions in the competitive electricity market to analyse these issues measured energy output from sites in the warwick wind trials project wwtp is converted into revenue in a net present value npv framework for assessing commercial purchases of small wind systems variances in project variables are examined through npv simulations using monte carlo analysis to capture permutations of small wind project performance in the uk with and without the uk fit our research concludes that the proposed tariff amount of 30 5 p kwh will not significantly boost the economic attractiveness of mildly selective wwtp based sites in the uk furthermore the fixed tariff rate kwh generated could cause inefficiencies applied across uneven wind resource distribution the results of this study suggest further examination of policy related to micro generation in particular decentralised small wind projects

intergenerational health mobility an empirical approach based on the echp despite the importance of the study of health mobility few attempts have been made to measure intergenerational mobility not only in the european union but also in other countries such as united states this article is focused on the study of intergenerational health mobility using data from the european community household panel echp in particular the relationships between self assessed health of parents and their sons are analysed the evidence obtained suggests that in spain sons reported health depends significantly on the self assessed health of their fathers

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item

the renewable energy market in brazil current status and potential abstract renewable energy offers a range of options with which to meet the growing demand for energy particularly in the context of the pursuit especially in developing countries of economic development which takes into account social and environmental issues brazil has abundant natural sources of renewable energy such as wind and solar power hydraulic energy small hydroelectric plants ethanol and bio diesel these sources form part of the brazilian strategy aimed at satisfying the demand for 6300 mw of fresh capacity per year arising out of projected economic growth of 5 1 per year over the next 10 years renewable energy sources currently provide 47 2 of the internal supply of primary energy in brazil brazil has been pursuing a strategy of maintaining its renewable energy matrix and developing and providing incentives for further low carbon initiatives in this study we set out an overview of the renewable energy options available in brazil their current status the main positive results obtained to date and future potential we describe the market for renewable energy in brazil and examine specific public policies aimed at overcoming barriers to this market thereby promoting its consolidation and expansion

family background and economic status in finland the importance of family background for economic outcomes is analyzed using a finnish data set the estimates for intergenerational and sibling correlations in earnings are comparatively low by estimating the magnitude of family influence conditional on parental earnings children with poor parents are found to have lower intergenerational elasticities while the sibling resemblance is higher children with rich parents have higher intergenerational elasticities and the sibling resemblance is also higher except for daughters the results also indicate that the largest share of the intergenerational correlation is transmitted through observed characteristics such as education and in particular occupation jel classification d1 d3 j6
