credit constraints and the phenomenon of child labor abstract this paper develops an overlapping generations general equilibrium model where inefficient child labor arises due to credit constraints it derives a positive relationship between inequality in the distribution of income and the incidence of child labor looking at policy implications it shows how trade sanctions against countries using child labor may fail to reduce the incidence of child labor it discusses some alternative policies to reduce the incidence of child labor

the assessment education research on the economics of education increasingly influences the design of education policy the framework for the analysis is provided by human capital theory in which education is interpreted as an investment raising the future productivity of the individual and bringing other private and social benefits estimates of the private and social returns to education and of the effectiveness of schools and teachers can be used to guide the allocation of resources within the public sector in addition policy reforms in the uk have attempted to make public providers of education more responsive to the preferences of parents and students there is evidence that pupil attainment has risen in recent years but that the education system fails to provide equality of access or opportunity and may reinforce social and economic inequality copyright 2004 oxford university press

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

a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

fiscal policy expectation traps and child labor i introduction child labor is widespread in the contemporary world in fact the international labor organization ilo estimates that 246 million of the world s children aged 5 17 or 16 are child laborers most living in developing countries 1 recently there has been renewed interest in this topic among economists which has led to a series of theoretical studies with the aim of better understanding the causes and consequences of child labor in order to help guide appropriate policy responses as in grootaert and kanbur 1995 basu 1999 and basu and tzannatos 2003 for useful literature surveys typically theoretical models designed to address the important policy issues surrounding child labor posit that a family s decision to send a child to the labor market is taken only as a last resort in order to escape the dire consequences of poverty for example basu and van 1998 baland and robinson 2000 show that this response on the part of the family may be stronger in a dynamic setting because contracts between children and adults are not self enforcing and capital markets are incomplete 2 in this case an adult decision maker may not only send their children to work to escape poverty in the present but do so to escape poverty in the future as well this decision will hinder a child s ability to accumulate human capital and can lead to persistent cycles of poverty and child labor across generations 3 we begin by showing that a benevolent government can address the incidence of child labor that results from the non enforceability of intergenerational contracts and incomplete capital markets through the appropriate use of fiscal policy and that this policy is pareto improving it is then shown that if society s confidence in their government is incomplete this lack of confidence can render the same fiscal policy ineffective in other words if households do not believe that the government will follow through on their policy promise then in fact it is quite possible that the government will not be able to follow through on their promise as a result of these beliefs 4 this self reinforcing nature of fiscal policy in the presence of uncertainty can leave a country in an expectations trap with a low level of human capital and child labor 5 to formally demonstrate this fiscal policy expectations trap hypothesis we employ a three period overlapping generations model in which child labor exists 6 this stylized setup will keep the dynamics manageable and allow us to highlight the effects of uncertainty also within this framework we introduce a missing intergenerational contracts market in conjunction with a human capital production function that exhibits a threshold with respect to parental human capital which gives rise to two locally stable steady states there is a good equilibrium where there is a relatively high level of parental human capital which results in a high level of income and no child labor and there is a bad equilibrium where there is a relatively low level of parental human capital which results in a low level of income and positive child labor this low income child labor equilibrium is the standard poverty trap scenario that typically exists in a deterministic economy with multiple equilibria it is then shown that a benevolent government can replicate the missing intergenerational contracts market with a pay as you go social security program thereby eliminating this component of child labor in an economy with perfect foresight in addition it is also shown that this policy is pareto improving in the sense that all generations are strictly better off under this policy except the initial old who are no worse off the dynamics of this social security program are intuitive if child labor is one possible mechanism adults can use to redistribute resources from their children then the government can reduce this incentive by announcing a social security program that will begin during the current adults old age an institutional intergenerational contract

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

the political economy of gender explaining cross national variation in the gender division of labor and the gender voting gap mainstream political economy has tended to treat the family as a unit when examining the distributional consequences of labor market institutions and of public policy in a world with high divorce rates we argue that this simplification is more likely to obscure than to instruct we find that labor market opportunities for women which vary systematically with the position of countries in the international division of labor and with the structure of the welfare state affect women s bargaining power within the family and as a result can explain much of the cross country variation in the gender division of labor as well as the gender gap in political preferences

staying on in full time education the educational participation rate of 16 year olds this paper presents a time series analysis of the socioeconomic factors influencing the propensity of sixteen year olds to stay on in full time education in england and wales the econometric methodology employed relies on cointegration and general to specific techniques the results suggest that the main factors influencing staying on are the rate of return to education changing social class structure unemployment rates and the introduction of special employment and training measures such as the youth training scheme copyright 1991 by the london school of economics and political science

using maimonides rule to estimate the effect of class size on scholastic achievement the twelfth century rabbinic scholar maimonides proposed a maximum class size of 40 this same maximum induces a nonlinear and nonmonotonic relationship between grade enrollment and class size in israeli public schools today maimonides rule of 40 is used here to construct instrumental variables estimates of effects of class size on test scores the resulting identiecation strategy can be viewed as an application of donald campbell s regression discontinuity design to the class size question the estimates show that reducing class size induces a signiecant and substantial increase in test scores for fourth and efth graders although not for third graders when asked about their views on class size in surveys parents and teachers generally report that they prefer smaller classes this may be because those involved with teaching believe that smaller classes promote student learning or simply because smaller classes offer a more pleasant environment for the pupils and teachers who are in them mueller chase and walden 1988 social scientists and school administrators also have a longstanding interest in the class size question class size is often thought to be easier to manipulate than other school inputs and it is a variable at the heart of policy debates on school quality and the allocation of school resources in many countries see e g robinson 1990 for the united states ofsted 1995 for the united kingdom and moshel ravid 1995 for israel this broad interest in the consequences of changing class size

the family and the state the immaturity of children sometimes precludes efficient arrangements between children and parents or others responsible for child care the difficulty in establishing efficient relations within families provides the point of departure for our interpretation of the heavy state involvement in the family the authors believe that a surprising number of state interventions mimic the agreements that would occur if children were capable of arranging for their care many regulations of the family improve the efficiency of family activities these interventions include subsidies to education and training social security and other old age support subsidies to births laws that limit access to divorce and the sale of children and laws that require parents permission for early marriage and other choices of children families that leave bequests can force children to repay parents for investments in human capital by reducing bequests therefore these families do not underinvest in childrens human capital by contrast families that do not leave bequests often poorer families do underinvest in children the state may subsidize schools and other training facilities to raise investments in children by poorer families to efficient levels authors modified

social motives vs social influence an experiment on interdependent time preferences we report experimental evidence on the effects of social preferences on intertemporal decisions to this aim we design an intertemporal dictator game to test whether dictators modify their discounting behavior when their own decision is imposed on their matched recipients we run four different treatments to identify the effect of payoffs externalities from those related to information and beliefs our descriptive statistics show that heterogeneous social time preferences and information about others time preferences are significant determinants of choices dictators display a marked propensity to account for the intertemporal preferences of recipients both in the presence of externalities social motives and or when they know about the decisions of their matched partners social influence we also perform a structural estimation exercise to control for heterogeneity in risk attitudes as for individual behavior our estimates confirm previous studies in that high risk aversion is associated with low discounting as for social behavior we find that social motives outweigh social influence especially when we restrict our sample to pairs of dictators and recipients who satisfy minimal consistency conditions

residential consumers in the cape peninsula s willingness to pay for premium priced green electricity a number of studies have explored the willingness i e stated willingness as opposed to actual willingness of consumers to pay a premium for green electricity in developed countries however little is known about how this translates into an emerging economy context this study investigates the level of willingness of residential households in south africa s cape peninsula to pay a premium for electricity from renewable energy it methodologically drew on recent contributions in the literature on norm motivated behaviour used to identify testable factors that could influence residential consumers willingness to pay wtp interestingly the study found a significant positive link between household income and wtp for green electricity contrary to the findings of some previous studies not only are higher income households more likely to pay a premium but typically they are also willing to pay a bigger premium it was also further established that the view that green electricity is reliable involvement in the recycling of waste and the belief that everyone should contribute to green electricity generation drive the wtp

estimating willingness to pay for renewable energy in south korea using the contingent valuation method the importance of renewable energy as a response to climate change is universally acknowledged however its successful implementation requires public approval and cooperation this study aims to identify the level of renewable energy acceptance in korea by estimating korean consumers additional willingness to pay wtp using the contingent valuation cv method which is the most widely used to analyze consumer preferences the estimation results indicate that korean consumers are willing to pay an additional usd 3 21 per month for electricity generated with renewable energy however wtp in korea is low relative to other advanced nations indicating that these values could be influenced through policies aimed at improving knowledge and acceptance of renewable energy sources among korean consumers

the political intergenerational welfare state abstract using a three period overlapping generations economy framework we characterize an intergenerational welfare state with endogenous education and pension under voting we show that although politically establishing pay as you go payg social security in isolation in a dynamically efficient economy will always reduce the capital investment and therefore the social welfare as expected in contrast politically implementing education pension policy package instead can improve both human and physical capital accumulation and social welfare over laissez faire however for this the political influence of the old has to be small thus limiting the size of the payg social security program

parental human capital investment and old age transfers from children is it a loan contract or reciprocity for indonesian families abstract this paper proposes two alternative models of intergenerational transfers linking parental investment in human capital of children to old age support the first model formulates these transfers as a pure loan contract and the second model as self enforcing reciprocity both models predict neutrality of intergenerational redistribution of resources within the family also known as the difference in income transfer derivatives property two models however provide different reasons for the failure of this property and yield different policy implications for parental human capital investment and provision of old age support specification tests on the indonesian family life survey data reject the pure loan model in favor of the reciprocity model the estimated difference in income transfer derivatives for this data is found to be significantly higher than the difference estimated by altonji hayashi and kotlikoff altonji et al 1992 altonji j g hayashi f and kotlikoff l j 1992 is the extended family altruistically linked direct tests using micro data the american economic review vol 82 5 1177 98 for the u s psid data

is increased public schooling really a policy for equality abstract empirical findings suggest different causes for higher educational attainment among children of high income earners either that poor parents are credit constrained or that parental human capital per se is important in the educational process my theoretical results show how these two diverging results can be brought together parental and public investments complement each other in the educational process because higher educated parents take advantage of increased productivity educational equality between rich and poor children is not necessarily promoted by further investments in public schooling moreover i show that educational investments in low skilled parents have spill over effects on their children and therefore have an unambiguously positive impact on equality

what does she see in him the effect of sharing on the choice of spouse all husbands and wives share in the spoils of marriage sharing makes each partner a residual claimant and encourages spouses to provide marital inputs however because each spouse is only a partial residual claimant each may be inclined to provide a suboptimal level of marital inputs the choice of spouse influences the level of distortion and under some circumstances the eficient mating is between individuals of equal value people tend to end up choosing partners of approximately their own social worth romantic choices appear to be a delicate compromise between one s desire to capture an ideal partner and one s realization that he must eventually settle for what he deserves

uncertain altruism and investment in children the authors discuss the concept of parental uncertainty about their childrens altruism and the consequences for investment in childrens human capital in this paper we show that if parents are uncertain about their childrens altruism but are at least sure that they will receive some support from their children then the unique optimal investment is the efficient one uncertainty over the exact level of the retirement gift does not alter the conclusion of the perfect certainty case even when parents are risk averse alternatively parents may not know enough about their childrens altruism to feel completely confident that some gift will be forthcoming regardless of the size of their investment under this assumption we show that the optimal investment must be less than the efficient amount excerpt

population age structure intergenerational transfer and wealth a new approach with applications to the united states this paper focuses upon intergenerational transfers overlapping generation models generational accounting and life cycle saving while assuming golden rule steady states and stable age profiles of transfers and economic activity using 1987 us data synthetic cohort methods were employed to explore how resource allocation over the life cycle generates real wealth and transfer wealth through the family public sector and financial markets while data problems assumption violations and accounting framework shortcomings would not permit firm conclusions transfer wealth in the us nonetheless seems to be about 2 3 greater than real wealth social security wealth medicare wealth and government debt are the main positive forms of wealth and together have greater value than real wealth transfer wealth must therefore displace holdings of physical capital and lead to lower labor productivity and higher interest rates

residential willingness to pay for deep decarbonization of electricity supply contingent valuation evidence from hong kong abstract motivated by the government s proposed target of reducing co2 emissions by 30 of the 2005 level in the year 2020 we estimate the residential willingness to pay wtp for deep decarbonization of hong kong s electricity supply which is heavily dependent on coal fired generation our contingent valuation survey conducted in 2016 of 1460 households yields dichotomous choice data based on the respondents answers to a series of closed ended questions such data are less susceptible to the strategic bias that often plagues self stated wtp data obtained by direct elicitation via open ended questions using binary choice models we find that average wtp is 48 51 relative to current bills if the decarbonization target is achieved via natural gas generation and renewable energy however estimated wtp declines to 32 42 when decarbonization entails additional nuclear imports from china as the projected bill increase caused by the target s implementation is 40 our wtp estimates support the government s fuel mix policy of using natural gas and renewable energy to displace hong kong s coal generation

the intergenerational state education and pensions allocation is inefficient when generations overlap this failure can be mitigated by properly designed social arrangements we show that public financing of education and public pensions can be designed to implement an intergenerational transfer scheme supporting the complete market allocation neither the public financing of education nor the pension scheme we consider resemble standard ones in our mechanism via the public education system the young borrow from the middle aged to invest in human capital they pay back the debt via a social security tax the proceedings of which finance pension payments when the complete market allocation is achieved the rate of return implicit in this borrowinglending scheme should equal the market rate of return

dynamic auction environment with subcontracting this article provides evidence on the role of subcontracting in the auction based procurement setting with private cost variability and capacity constraints we demonstrate that subcontracting allows bidders to modify their costs realizations in a given auction as well as to control their future costs by reducing backlog accumulation restricting access to subcontracting raises procurement costs for an individual project by 12 and reduces the number of projects completed in equilibrium by 20 the article explains methodological and market design implications of subcontracting availability

consumer rationality and the status quo received microeconomic theory presumes rational consumers maximize utility over all commodity bundles recent analysis however suggests that a consumer s status quo may limit economic rationality bias consumer decisions and induce serious errors in survey based valuations of public and private goods using regression and choice theoretic frameworks we investigate the existence of status quo effects in the consumer valuation of a particular unpriced product the reliability of residential electrical service such valuations have become important in electric utility resource planning and rate making we find substantial status quo effects which must be addressed in welfare comparisons regarding electric service reliability

households willingness to pay for safeguarding security of natural gas supply in electricity generation abstract security of energy supply is a major issue for all eu member states due to europe s increasing dependence on imported fossil fuel sources and the continuous rise in energy demand the latter is of particular importance in electricity sector given the continuously increasing use of gas for electricity generation in order to properly tackle with the problem concerted actions are required by the eu member states in several levels i e legislative political etc nevertheless these actions will come at an additional cost paid by the society either through increased electricity bills or through public financing for energy security investments thus such policies should be justified on the basis of cost benefit analysis towards this direction it may be necessary to take into account non market costs and benefits i e the value that consumers place on interruptions avoided in order to explore households perceptions and willingness to pay for securing gas supply for electricity production an empirical study was conducted by means of the contingent valuation method the results indicate that consumers are willing to pay a premium on their electricity bills in order to internalize the external costs of electricity production in terms of energy security which are caused from imported fuels

wind hydro or mixed renewable energy source preference for electricity products when the share of renewable energy increases abstract while the share of renewable energy especially wind power increases in the energy mix the risk of temporary energy shortage increases as well thus it is important to understand consumers preference for the renewable energy towards the continuous growing renewable energy society we use a discrete choice experiment to infer consumers preferences when the share of renewable energy increases the study results indicate that consumers are generally willing to pay extra for an increasing share of renewable energy but the renewable energy should come from a mixture of renewable energy sources we also found that consumers prefer to trade with their current supplier rather than another well known supplier this study contributes to the energy portfolio theories and the theory of energy diversification in a consumer perspective the managerial implications of this study are also discussed

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

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

a bequest constrained economy welfare analysis bequest constraints have played a major role in discussions of debt neutrality but their welfare implications were not sufficiently dealt with in the literature in this paper we focus on the welfare implications of bequest constraints we found that when institutional constraints to the transfer of resources from children to their parents exists the welfare of the parents generation may be improved by an old age security scheme such a scheme is justified not by income redistribution consideration as is typically the case but rather on pure efficiency grounds due to its intergenerational transfer role the social security scheme is pareto improving with altruistic parents if in addition the real income effect which tends to raise children consumption is relatively strong this abstract was borrowed from another version of this item

efficiency enhancing signalling in the samaritan s dilemma suppose an altruistic person a is willing to transfer resources to a second person b if b comes upon hard times if b anticipates that a will act in this manner b will save too little from both agents point of view this is the samaritan s dilemma this paper shows that the undersaving result is mitigated if we relax the standard assumption of complete information because if a is uncertain about how big b s need for support is b will have an incentive to signal that he is in great need by saving more than he otherwise would have done

paying for mitigation a multiple country study a contingent valuation study conducted in china sweden and the united states was used to investigate citizens willingness to pay wtp for reducing co2 emissions we find that a majority of the respondents in all three countries believe that the mean global temperature has increased over the last 100 years and that humans are responsible for the increase the share of americans that believes these statements is smaller and a relatively larger share of americans also believes that nothing can be done to stop climate change sweden has the highest wtp while china has the lowest jel q51 q54

giving it now or later altruism and discounting we experimentally study the e ect of time on altruism by postponing payments in a standard dictator game subjects allocate a future payment between themselves and others since both the payoffs of the dictator and the receiver are delayed until the same time standard intertemporal utility maximization would predict that waiting time should not affect the dictator s choice in this respect we observe that dictators decisions are not affected as long as the time interval between the decision and payment is not large on the other hand for large time gaps subjectsbecome more self interested

experimental estimates of education production functions this paper analyzes data on 11 600 students and their teachers who were randomly assigned to different size classes from kindergarten through third grade statistical methods are used to adjust for nonrandom attrition and transitions between classes the main conclusions are 1 on average performance on standardized tests increases by four percentile points the first year students attend small classes 2 the test score advantage of students in small classes expands by about one percentile point per year in subsequent years 3 teacher aides and measured teacher characteristics have little effect 4 class size has a larger effect for minority students and those on free lunch 5 hawthorne effects were unlikely

household willingness to pay for green electricity in slovenia abstract this paper analyses the willingness to pay for electricity generated from renewable energy sources in slovenia the results confirm that age household income education and environmental awareness play the most important role in explaining household attitudes to green electricity programmes while the willingness to participate in green electricity programmes is influenced by education and environmental awareness the willingness to pay for green electricity predominantly depends on household income the results imply that green marketing should be accompanied by awareness raising campaigns and should target younger well educated and high income households the expressed median willingness to pay is found to exceed the current level of mandatory charges for green electricity nevertheless recent increases in final electricity prices might have already exhausted the capacity for additional voluntary contributions

insurance self protection and the economics of terrorism abstract this paper investigates the rationale for public intervention in the terrorism insurance market it argues that government subsidies for terror insurance have the effect of discouraging self protection and limiting the negative externalities associated with self protection cautious self protective behavior by a target can hurt public goods like national prestige if it is seen as giving in to the terrorists and may increase the loss probabilities faced by others by encouraging terrorists to substitute toward more vulnerable targets we argue that these externalities in protection are essential for normative analysis of government intervention in insurance markets and may also explain why availability problems in this market have engendered much stronger government responses than similar problems in other catastrophe insurance markets

public trust and corruption perception disaster relief public trust in government and nongovernment organizations is essential to the public s willingness to donate and to support those organizations we measure public trust in disaster aid using people s perception of these organizations effectiveness in delivering aid relief to the victims of two recent major earthquakes in china based on the survey data collected in 2013 from about 2100 residents in hong kong we document the vulnerability of these residents trust perceptions in aid delivery we find that the sharp decline in trust perception is highly negatively correlated with their perception of corruption of local governments in china

measuring the social value of nuclear energy using contingent valuation methodology abstract as one of the promising energy sources for the next few decades nuclear energy receives more attention than before as environmental issues become more important and the supply of fossil fuels becomes unstable one of the reasons for this attention is based on the rapid innovation of nuclear technology which solves many of its technological constraints and safety issues however regardless of these rapid innovations social acceptance for nuclear energy has been relatively low and unchanged consequently the social perception has often been an obstacle to the development and execution of nuclear policy requiring enormous subsidies which are not based on the social value of nuclear energy therefore in this study we estimate the social value of nuclear energy consumers willingness to pay for nuclear energy using the contingent valuation method cvm and suggest that the social value of nuclear energy increases approximately 68 5 with the provision of adequate information about nuclear energy to the public consequently we suggest that the social acceptance management in nuclear policy development is important along with nuclear technology innovation

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

willingness to pay for improved air quality in sweden the aim of the paper is to quantify individual willingness to pay measures of improved air quality in sweden by using the contingent valuation method cvm such measures are important for policy makers when deciding about public investments and policy instruments in order to regulate environmental impacts e g from road transportation and industry the mean willingness to pay wtp for a 50 reduction of harmful substances where the respondents live and work was about 2000 sek year which is of the same order of magnitude as earlier stated preference studies in nordic countries most parameters in the econometric analysis had the expected sign wtp was increasing in income wealth and education it was larger for men members of environmental organizations people living in big cities which are on average more polluted and people who own their house or apartment it was lower for retired people however the additional wtp for people in big cities although significantly higher than for other people

the supply of children s time to disabled elderly parents i introduction in recent years economists have become increasingly interested in intergenerational transfers of both time and money 1 such transfers may be motivated by altruism or exchange models of altruism assume that a person s utility depends on the consumption or utility of other family members and her own consumption for example children may supply unpaid informal care to aging parents because their utility increases when their parents are happier one of the most striking predictions of models of altruism is that public subsidies tend to crowd out transfers by altruistic individuals especially if the subsidy is financed by taxing the altruistic individual becker 1974 in exchange models there is typically altruism but one family member such as a parent can induce a relative such as a child or kid 2 to provide more services or money than the relative would normally provide by threatening to withhold a bequest to the extent that this is so one would plausibly expect more care and attention to be provided to wealthy parents when there is more than one kid more care should be provided because the threat of disinheritance is more credible when there is competition between kids for bequests in a well known article bernheim shleifer and summers 1985 hereafter referred to as bss found empirical support for the strategic bequest motive based on an observed positive relationship between children s visits and telephone calls to elderly parents per child as the measure of attention and bequeathable wealth per child as the measure of the financial motivation for providing such attention one might expect this result to extend to decisions about direct provision of help informal care that kids may provide to parents the marginal benefit of such care is plausibly greater than the benefit derived from a visit or telephone call in a recent article however we found no evidence that the strategic bequest motive is an important determinant of the amount of informal care kids provide or a related decision whether or not to place the parent in a nursing home sloan hoerger and picone 1996 we focused on the distinction between cognitively aware parents who can threaten to disinherit their kids and cognitively unaware parents who cannot disinherit and examined whether this distinction had any effect on the probability that the parent entered a nursing home or on amounts of formal and informal care received if the parent remained in the community any strategic effects were swamped by the greater marginal benefit of care to the parent when the parent was cognitively unaware moreover among the cognitively aware richer parents actually received less informal care contrary to the strategic model s predictions unfortunately in past research on intergenerational transfers of time and money it was not possible to control for the wealth wage and other characteristics of kids to the extent that kid s wealth and wage were positively correlated with parent s wealth which was observed the parameter estimates on parent s wealth may be negatively biased although parent s wealth and kid s wealth and wage rates are plausibly positively correlated they have opposite effects on the supply of kid s time according to the strategic bequest model that is potential bequests from a parent may be less attractive to rich kids and therefore induce less care we test the strategic bequest model using information on elderly parents and their children from two linked surveys the 1989 national long term care survey nltcs for elderly individuals and the survey of informal caregivers sic for a subsample of the elderly s children using these data we can include explicit measures of kid s wealth and wage rates thereby avoiding the possible bias introduced by a correlation between parent s and kid s wealth and wages also the data sets provide information on several pertinent health cognitive and functional status variables which are not typically observed in surveys of financial status

a new test of borrowing constraints for education we discuss a simple model in which parents and children make investments in the children s education investments for other purposes and parents can transfer cash to their children we show that for an identifiable set of parent child pairs parents will rationally under invest in their child s education for these parent child pairs additional financial aid will increase educational attainment the model highlights an important feature of higher education finance the expected family contribution efc that is based on income assets and other factors the efc is neither legally guaranteed nor universally offered our model identifies the set of families that are disproportionately likely to not provide their full efc using a common proxy for financial aid we show in data from the health and retirement study that financial aid increases the educational attainment of children whose families are disproportionately likely to under invest in education financial aid has no effect on the educational attainment of children in other families the theory and empirical evidence identifies a set of children who face quantitatively important borrowing constraints for higher education

altruism fertility and the value of children health policy evaluation and intergenerational welfare abstract this paper accounts for the value of children and future generations in the evaluation of health policies this is achieved through the incorporation of altruism and fertility in a value of life type of framework we are able to express adults willingness to pay for changes in child mortality and also to incorporate the welfare of future generations in the evaluation of current policies our model clarifies a series of puzzles from the literature on the value of life and on intergenerational welfare comparisons we show that by incorporating altruism and fertility into the analysis of the recent u s experience the estimated welfare gain of a young adult from reductions in mortality easily doubles

the economics of child custody i develop a model of marriage in which spouses decide on investments in child quality during marriage and on the allocation of child custody should they divorce the custodial allocation determines the share of the marital surplus each spouse appropriates which in turn influences spouses investment incentives the custodial allocation therefore has both distributional and efficiency consequences i derive the equilibrium investments and optimal custodial allocation and identify three channels through which making divorce easier affects child welfare investments in child quality during marriage the likelihood of divorce and the allocation of custody if divorce occurs

education and the poverty trap an overlapping generations model is constructed in which individual wealth is related to educational attainment and in which liquidity constraints may induce children to invest in a sub optimal level of education given their ability financing for education is obtained from within the family abilities differ among children and may be related to parental ability stationary state equilibria are found to exist in which children of poorer families are caught in a poverty trap because of an inability to finance their education the role of redistributive policy is studied in this context

forward and backward intergenerational goods why is social security good for the environment this paper studies the ability of nonmarket institutions to invest optimally in forward intergenerational goods figs such as education and the environment when agents are selfish or exhibit paternalistic altruism we show that backward intergenerational goods bigs such as social security play a crucial role in sustaining investment in figs without them investment is inefficiently low but with them optimal investment is possible we also show that making the provision of bigs mandatory crowds out the voluntary provision of figs and that population aging can increase investment in figs

the state of the art of environmental valuation with discrete choice experiments abstract this paper provides with a review of the state of the art of environmental valuation with discrete choice experiments dces the growing body of literature on this field serves to emphasize the increasing role that dces are playing in environmental decision making in the last decade the paper attempts to cover the full process of undertaking a choice experiment including survey and experimental design econometric analysis of choice data and welfare analysis the research on this field is found to be intense although many challenges are put forward e g choice task complexity and cognitive effort experimental design preference and scale heterogeneity endogeneity or model uncertainty reviewing the state of the art of dces serves to draw attention to the main challenges that this methodological approach will need to overcome in the coming years and to identify the frontiers in discrete choice analysis

antisocial security the puzzle of beggar thy children policies the u s social security program has irrevocably transferred substantial wealth from workers to their ostensibly altruistic parents after some alternative explanations for this paradox are addressed a formal model is developed to show that a majority of rational voters who care about their descendants can support the preservation of current benefits for themselves but accept the prospect of social security s future retrenchment incorporating elements of tabellini s 2000 positive theory of social security and benabou and ok s 2001 analysis of income mobility the model identifies specific forces affecting this time varying individual support for social security these forces are embodied in three hypotheses related to income mobility relative income level and age an ordered logit analysis of cumulative anes data supports these hypotheses

ownership and the regulation of wildlife ownership and the regulation of wildlife the use of wildlife resources is governed by a combination of private contracts and public regulations most often private landowners control access rights and government agencies regulate hunting and other uses this paper shows that these institutions depend on wildlife values and the ability of private landowners to control access to species that inhabit their land logit regressions and literary sources are used to test implications about private hunting rights and state regulations the data support the view that private legal and political forces have led to institutions that vary in ways consistent with wealth maximization i introduction most resources are not exclusively private or public but are governed by a mixture of private and public institutions in the united states wildlife populations are no exception state governments usually regulate hunting trapping and fishing federal agencies protect endangered species and private landowners largely control access rights to habitat although it is true that owning deer or elk is different from owning cattle or sheep the facts refute the common assertion that wildlife are unowned or have no value existing laws and regulations define property rights to many dimensions of wildlife and in many areas access rights to wildlife are routinely bought and sold economists typically view private contracts as arrangements that maximize the value of resources governed by the contract on the other hand public institutions are given less credit becker 1983 peltzman 1976 stigler 1971 and others have argued that interest groups can influence political decisions and ultimately distort outcomes from an efficiency viewpoint private and public institutions are distinct barzel 1989 becker and murphy 1988 mcmanus 1975 and wittman 1989 have advanced an alternative view that institutions including government not only reflect the optimizing activity of individuals but also maximize the net value of resources alchian 1950 argued that persistent and surviving institutions are likely efficient because most features of american wildlife institutions have persisted for two centuries the likelihood of efficiency seems high relative to the likelihood of pervasive inefficiency in part i test this efficient organization hypothesis by treating both private and public wildlife institutions as the result of efforts to increase the value of wildlife specifically i argue that the content of private wildlife controls and government regulations depends on the value of wildlife stocks as well as on the ability of landowners to contract with each other and with wildlife users to control wildlife stocks and access to them ii the contracting problem with wildlife it is costly to establish ownership of wildlife stocks because the ownership patterns of land do not always coincide with the populations territories if a stock of wildlife is the only valuable attribute of a parcel of land then the value of the land is maximized when land ownership coincides with the population s territory under these conditions wildlife would be quite similar economically to domestic animals the habitat would still be natural however and the species would still be considered wild below i consider the usual case in which wildlife is not the only valued use of land optimal landownership and wildlife territory assume that a homogeneous tract of land has two potentially valuable attributes agriculture and wildlife next assume that the size of the wildlife stock is not influenced by agriculture finally assume that the stock of wildlife is composed of homogeneous units that is individual animals and that the value of wildlife is tied to the value of the animals and not to the value inherent in the existence of a species 1 if the land is used for agricultural production then the optimal size of the land tract in acres is s

how responsive are private transfers to income evidence from a laissez faire economy abstract in recent years there has been burgeoning interest in how private transfers respond to household income or transfer derivatives much of it is fueled by the specter of crowding out the more responsive are private transfers the more likely they could be supplanted by expansions in public transfers weakening or destroying the latter s distributive impact yet there is also an emerging consensus that actual transfer derivatives are trivial at least for the united states suggesting that crowding out might loom larger in the minds of some economists than in the data but perhaps crowding out is a fait accompli in the united states accordingly we focus on the philippines which has a much smaller public sector we also pursue a novel theoretical angle which generates a sharp non linear relationship between private transfer receipts and income in the form of a spline our empirical work applies recently developed estimation techniques that treat the spline s threshold as an unknown parameter and they uncover transfer derivatives much larger than conventional methods reveal notably private transfers patterns are consistent with altruistic preferences effective risk sharing or both in accord with theoretical predictions however strong transfer derivatives prevail only among low income households our findings suggest that attempts to aid the poor could be thwarted by private responses which leak benefits to richer households in the form of lighter burdens of support for less fortunate kin so the problems that operative private transfers create for public redistribution policy first pointed out by becker and barro over 25 years ago do indeed matter empirically

the intergenerational welfare state and the rise and fall of pay as you go pensions this article develops a theory of the two armed intergenerational welfare state consistent with key features of modern welfare arrangements and uses it to rationalise the rise and fall in generosity of pay as you go pensions solely on efficiency grounds by using the education arm a dynamically efficient welfare state is shown to improve upon long run laissez faire even when market failures are absent to release these downstream welfare gains without hurting any transitional generation help from the pension arm is needed in the presence of an intergenerational education externality pensions initially rise in generosity but can be replaced by fully funded pensions eventually

social acceptance of renewable energy sources a review of contingent valuation applications abstract this paper presents a literature review addressing the public acceptance of renewable energy as a replacement for fossil fuels in electricity production this review was motivated by the global tendency for a substitution of conventional fuels by renewable energy sources res during the global financial crisis it studies research on the preferences and attitudes of local communities towards investments in renewable energy projects and their perception of the use of new energy technologies in their daily lives through various case studies worldwide an effort is made to identify the parameters that influence consumers energy behaviour together with their interest or lack thereof in the environmental impact of using fossil fuels to produce energy and their willingness to reduce it applications of contingent valuation are examined which are employed to analyse public attitudes towards the use of res for electricity production willingness to pay is observed to be correlated to socioeconomic characteristics including education interest in environmental issues and knowledge of res finally the profile of a typical green energy consumer and appropriate policy paths for the penetration of res into the energy market are outlined

pay as you go or funded social security a general equilibrium comparison abstract this paper demonstrates that the analysis of fiscal sustainability of social security must include the education funding dimension of public policy which affects the productivity of future workers this fact is true under both social security regimes pay as you go payg and fully funded ff we consider an olg economy where the government in addition to running social security also funds education via a dedicated tax the education tax rates are chosen in each period by a majoritarian rule we demonstrate contrary to conjectures in the literature that the ff social security system produces political support for a relatively higher compared to payg education funding and hence generates higher rates of human capital accumulation physical capital accumulation and economic growth furthermore it also results in a comparatively lower degree of income inequality

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

reciprocity under brief and long time delays we report the results from three experiments embedded in the same overarching design which extends the gift exchange paradigm for the study of worker employer relationships we focus on the effect of the length of the delay between the time at which workers learn their wage and when they choose an effort level on the relationship between wage and effort we compare effort choices made within a few hours with those made several weeks afterward we find that the strength of the wage effort relationship decreases over time and this change appears to be driven by workers who receive low wages jel c91 j33 m52

eliciting public preference for nuclear energy against the backdrop of global warming one of the most important issues related to sustainability is to reduce the use of fossil fuels due to the reduction in greenhouse gases ghg emission nuclear power results in low carbon emissions and is thus important to mitigating the adverse effects of global warming and climate change however the downside of nuclear power cannot be overlooked and consequently nuclear power is a controversial issue in many countries around the world thus an important question concerns how people should support nuclear power do the climate and energy security benefits of nuclear power outweigh its risks and costs therefore we use a modified double bounded contingent valuation model to explore the attitudes and the willingness to pay wtp of a country in order to demonstrate its implications for policy we confirm that supporters and opponents of nuclear power are balanced both in terms of their numbers and in terms of their wtp the policy implication is that people do not support any dramatic increase or reduction in nuclear power and that nuclear power should still be an important means of generating electricity in taiwan the current share of nuclear power in electricity generation of 20 should be maintained in the near future

willingness to pay and policy instrument choice for climate change policy in the united states abstract this paper provides the first willingness to pay wtp estimates in support of a national climate change policy that are comparable with the costs of actual legislative efforts in the u s congress based on a survey of 2034 american adults we find that households are on average willing to pay between 79 and 89 per year in support of reducing domestic greenhouse gas ghg emissions 17 by 2020 even very conservative estimates yield an average wtp at or above 60 per year taking advantage of randomized treatments within the survey valuation question we find that mean wtp does not vary substantially among the policy instruments of a cap and trade program a carbon tax or a ghg regulation but there are differences in the sociodemographic characteristics of those willing to pay across policy instruments greater education always increases wtp older individuals have a lower wtp for a carbon tax and a ghg regulation while greater household income increases wtp for these same two policy instruments republicans along with those indicating no political party affiliation have a significantly lower wtp regardless of the policy instrument but many of these differences are no longer evident after controlling for respondent opinions about whether global warming is actually happening

public education and pensions in democracy a political economy theory a dynamic political economy theory of scal policy is presented to explain the simultaneous existence of public education and pensions in modern democracies the driving force of the model is the intergenerational conict over the allocation of the public budget successive generations of voters choose scal policies through repeated elections the political power of elderly voters creates the motive for adults to support public investment in the human capital of future generations since it expands future pension possibilities we characterize the markov perfect equilibrium of the voting game in a small open economy the equilibrium reproduces salient features of intergenerational
