speculative investor behavior and learning as traders learn about the true distribution of some asset s dividends a speculative premium occurs as each trader anticipates the possibility of reselling the asset to another trader before complete learning has occurred small differences in prior beliefs lead to large speculative premiums during the learning process this phenomenon helps explain a paradox concerning the pricing of initial public offerings the result casts light on the significance of the common prior assumption in economic models

international trade of scarce water abstract recent analyses of the evolution and structure of trade in virtual water revealed that the number of trade connections and volume of virtual water trade have more than doubled over the past two decades and that developed countries increasingly import water embodied in goods from the rest of the world to alleviate pressure on domestic water resources at the same time as demand continues to increase and climate change threatens to alter hydrological cycles water scarcity is a growing problem does research into virtual water trade need to consider water scarcity and differentiate flows out of water scarce regions from flows out of water abundant regions previous studies sum and compare virtual water volumes originating in countries experiencing vastly different degrees of water scarcity we therefore incorporate water scarcity into an assessment of global virtual water flows we use input output analysis to include indirect virtual water flows we find that the structure of global virtual water networks changes significantly after adjusting for water scarcity

optimal growth with many consumers abstract a method is described for constructing all pareto optimal allocations for a dynamic economy with many heterogeneous consumers under certainty in which both the technology and consumer preferences are recursive but preferences need not be additively separable over time optimal perfect foresight competitive equilibrium allocations are obtained through the study of a dynamic program for an economy with one consumption good sufficient conditions are given for the existence of a unique interior stationary distribution of consumption and wealth for a two person exchange economy sufficient conditions are given for the global asymptotic stability of the unique interior stationary point

network perspective of embodied pm2 5 a case study abstract economic growth due to social activities such as industrialization urbanization population growth and transportation in countries like india is coupling with an increase in pm 2 5 emissions which are main contributors to air pollution in this paper the embodied pm 2 5 emissions generated from economic activities in india were investigated we quantified the pm 2 5 emissions from each economic sector based on input output analysis ioa also the control relations within these economic sectors were identified based on ecological network analysis ena to determine the dominance and dependency of each sector the results showed that 86 4858 kt of total pm 2 5 emissions were direct and 14 812 kt were indirect in 2010 furthermore ena based results represented the pairwise control relationships among sectors by finding that sale maintenance and repair of motor vehicles retail sale of fuel chemicals and chemical products smelting of nonmetal mineral products and ordinary special machinery equipment were the dominant sectors that controlled the flow of embodied pm 2 5 emissions from other sectors such as construction agriculture mining and dressing catering services and waste manufacturing and recycling it is suggested that ena be adopted as a more systematic approach to uncover pm 2 5 flow pattern among the economic sectors as compared to traditional methods

transfer behavior in the health and retirement study measurement and the redistribution of resources within the family recent work by a number of economists has opened a debate about the role played by intergenerational transfers using the new health and retirement study hrs we are better able to address the issues involved contrary to the current literature on bequests we do not find that parents give transfers equally to all children rather we find that in the case of inter vivos transfers respondents give greaterfinancial assistance to their less well off children than to their children with higher incomes financial transfers to elderly parents are also found to be negatively related to the potential recipient s income these results hold both for the incidence of transfers and for the amounts in addition we allow for unobserved differences across families by estimating fixed effect models and find our results to be robust to these specifications a comparison of the hrs transfer data to other survey data demonstrates that the hrs is potentially quite useful for research on transfer behavior

from production based to consumption based national emission inventories abstract under the united national framework convention of climate change unfccc countries are required to submit national emission inventories nei to benchmark reductions in greenhouse gas ghg emissions depending on the definition and system boundary of the nei the mitigation options and priorities may vary the territorial system boundary used by the unfccc has been critiqued for not including international transportation and potentially causing carbon leakage to address these issues past literature has argued in favour of using consumption based nei in climate policy this article discusses several issues in moving from the standard production based nei to consumption based nei first two distinct accounting approaches for constructing consumption based nei are presented the approaches differ in the allocation of intermediate consumption of imported products second a consistent method of weighting production based and consumption based nei is discussed this is an extension of the previous literature on shared responsibility to nei third due to increased uncertainty and a wide system boundary it may be difficult to implement consumption based nei directly into climate policy several alternative options for incorporating consumption based inventories into climate policy are discussed

natural gas overview for world economy from primary supply to final demand via global supply chains abstract as the world is smoothing the transition towards a low carbon energy structure natural gas has occupied a critical position in global energy supply also globalization has catalyzed ever increasing indirect energy flows in international trade in order to present a comprehensive overview of natural gas use in globalized economy this paper applies the systems multi regional input output mrio analysis to track natural gas use from primary suppliers to final consumers via the links by producers in the world economy supported by typical statistics for the year of 2011 natural gas embodied in international trade is revealed amounting to 2722 1 bcm in magnitude up to 90 of total gas extraction for energy use indicating the intensive relocation of gas use by trade 83 of traded embodied natural gas is associated with intermediate trade mainly from leading primary suppliers including russia usa and western asia to dominant final consumers like usa eu27 and east asia significant differences are found between direct and embodied natural gas flows consumption based resource efficiency can break the illusion of efficiency improvements and trade imbalance in terms of gas use can be opposite to the trade imbalance in conventional monetary terms this paper has constructed a comprehensive analytical framework to trace natural gas flows in globalized economy for the first time aiming to provide new insights for policy making

global overview for energy use of the world economy household consumption based accounting based on the world input output database wiod abstract globalization has integrated nations into a world economy based on the world input output database wiod this paper explored the energy use of the world economy under a household consumption based mrio multi region input output accounting scheme pertaining to normative economics the household consumption based mrio accounting scheme corresponds to the value judgement of household consumption being the ultimate driver of the economy which complements existing accounting methods based on different viewpoints the energy use associated with the internationally traded products is calculated to be around one fifth of the global total energy consumption for china as the largest exporter and also the biggest deficit economy in terms of energy use its trade imbalance is nearly the summation of that of the united states the united kingdom japan and germany energy self sufficiency rates by supply and by demand are respectively proposed while the united states economy as the largest importer maintains the majority of the energy welfare denoted by the onsite energy use at home china exports large quantities of energy use abroad for economies like germany south korea and taiwan they could be regarded as hubs that export a considerable amount of energy use abroad and absorb massive energy use from outside simultaneously for sustainable use of energy resources economies are suggested to carefully identify their roles in the global trading network of energy use

behavioral responses to inheritance tax evidence from notches in france abstract for the first time we exploit quasi experimental variation to investigate the impact of inheritance taxation on wealth accumulation using bunching and difference in differences methods we directly estimate several behavioral responses during lifetime rather than relying solely on observations at death our empirical findings shed new light upon wealth accumulation and bequest motives taken together the small responses to inheritance tax estimated cannot be supported by the desire to retain control over wealth

uncovering resource losses and gains in china s foreign trade abstract natural resource storages and flows play an important role in economic and social processes in this paper we explore the trade of primary commodities between china and its main trade partners during the years 2000 and 2008 emergy accounting is used to assess the environmental support associated with the resources exchanged mass emergy and financial capital export to import ratios confirm that economy level trade advantages should not just rely on capital flow a holistic evaluation of the trade process including resource environmental value should be performed to identify trade balance and stability results show that while china s imports monetary value is much larger than exports monetary value china receives more emergy environmental support in trade than it gives benefiting from the ability of primary resources to drive its economy developed economies characterized by a low emergy to money ratio gain more from trade of primary commodities with china developing and underdeveloped economies with higher emergy to money ratio lose in the environmental support balance to china indicating the existence of a potentially unsustainable trade imbalance

optimal embodied energy abatement strategy for beijing economy based on a three scale input output analysis abstract energy strategies in china s 11th and 12thzfive year plan failed to reduce the total energy consumption and misled the implementation of energy saving measures as they were focused towards the direct energy input as well as formulated based on incomplete energy consumption information therefore an optimal energy abatement strategy built on comprehensive information on overall embodied energy consumption is in urgent need adopting the three scale input output analysis this study uses beijing as a case to depict a specific urban economy s overall energy consumption impacted by local direct energy use domestic and foreign trade the results show that energy embodied in domestic trade dominated beijing s energy consumption while local direct energy is accounting for less than 1 3 of beijing s total embodied energy consumption the quantity of energy embodied in imports far exceeds that embodied in exports making the city a net embodied energy importer and indicating that policies considering direct energy use only will cause energy leakage problem these findings suggest that the current measures such as displacing energy intensive sectors to other regions lead to local reduction but overall rise moreover analysis for five abatement scenarios average intensity share absolute share discriminatory absolute and discriminatory intensity was carried out to figure out the optimal abatement strategy for beijing due to less loss of potential output it is found that intensity share scenario is the optimal one among all the scenarios concerned analysis in this study suggests that each region should break limits of self centered perceptions and multi scale governance for more appropriate responsibility assignment is recommended for overall energy abatement

ghg emissions embodied in macao s internal energy consumption and external trade driving forces via decomposition analysis abstract as a member of the kyoto protocol macao faces the enormous challenge to tackle with energy conservation and greenhouse gas ghg emission reduction though many studies have been devoted to understanding macao s ghg emissions from energy consumption and external trade an investigation of the underlying driving forces is still absent therefore this study decomposed the energy related emissions change and imbalance in embodied emissions of external trade during 2000 2011 respectively by using the logarithmic mean divisia index lmdi method the economic scale effect and energy structure change were identified as the main driving factors of macao s increasing energy related emissions while trade structure and embodied emission intensity contributed to make macao a net importer of embodied emissions however some variations can be seen during the period concerned then the underlying reasons for the two decomposition results were further investigated on account of the results and analysis instructive policy implications can be put forward for macao to better proceed with energy conservation and emissions reduction

embodied carbon dioxide emission at supra national scale a coalition analysis for g7 bric and the rest of the world abstract presented in this study is an empirical analysis of embodied carbon dioxide emissions induced by fossil fuel combustion for the world divided into three supra national coalitions i e g7 bric and the rest of the world row via the application of a multi region input output modeling for 2004 embodied emission intensities for the three coalitions are calculated and compared with market exchange rate and purchase power parity separately used to investigate the difference between nominal and real production efficiencies emissions embodied in different economic activities such as production consumption import and export are calculated and analyzed accordingly and remarkable carbon trade imbalances associated with g7 surplus of 1 53 billion tons or 36 its traded emissions and bric deficit of 1 37 billion tons or 51 its traded emissions and approximate balance with row deficit of 0 16 billion tons or 3 its traded emissions are concretely revealed carbon leakages associated with industry transfer and international trades are illustrated in terms of impacts on global climate policies the last but not least per capita consumption based emissions for g7 bric and row are determined as 12 95 1 53 and 2 22 tons respectively and flexible abatement policies as well as equity on per capita entitlement are discussed

new evidence on altruism a study of tiaa cref retirees this paper investigates the role in household wealth accumulation of saving for bequests it employs data from a 1988 survey of tiaa cref annuitants designed to measure pension and other net worth as well as lifetime earnings about half of the households in the data plan to leave estates and the authors find that their behavior conforms with theoretical altruistic models for the same families the amount of wealth that the authors attribute to estate building is large nevertheless altruism towards one s children does not seem to be the major explanation of saving in the overall sample copyright 1996 by american economic association

the dynamics of efficient asset trading with heterogeneous beliefs this paper analyzes the dynamic properties of portfolios that sustain dynamically complete markets equilibrium when agents have heterogeneous priors we argue that the conventional wisdom that belief heterogeneity generates continuous trade and significant fluctuations in individual portfolios may be correct but it needs some qualifications we consider an infinite horizon stochastic endowment economy populated by many bayesian agents with heterogeneous priors over the stochastic process of the states of nature our approach hinges on studying the portfolios that decentralize pareto optimal allocations since these allocations are typically history dependent we propose a methodology to provide a complete recursive characterization when agents believe that the process of states of nature is i i d but disagree about the probability of the states we show that even though heterogeneous priors within that class can indeed generate genuine changes in the portfolios of any dynamically complete markets equilibrium these changes vanish with probability one if the true process consists of i i d draws from a common distribution and the support of some agent s prior belief contains the true distribution finally we provide examples in which asset trading does not vanish because either i no agent learns the true conditional probability of the states or ii some agent does not know the true process generating the data is i i d

tax avoidance and intra family transfers to what extent do people avoid taxes on intra family transfers be quests and gifts and how would integration unification of the dif ferent transfers taxes affect tax avoidance these issues are important for families and their welfare as well as for governments and their pos sibilities of raising revenue from transfer taxes in this paper we study the effects of transfer taxes on altruistic parents transfers to their chil dren using a theoretical model we find that altruistic parents do not necessarily tax minimize however in some cases when they do there is an infinitely large excess burden of a transfer tax we also find that integration of transfer taxes reduces tax avoidance all tax avoidance is eliminated with complete integration

coal use for world economy provision and transfer network by multi region input output analysis concerns surrounding climate change and environmental challenge make the coal utilization network essential not only for understanding the pattern of energy provision and transfer but also for illustrating the interaction between anthropogenic activities and ecological systems at global level this paper fills the research gap by dint of multi regional input output model to outline coal embodied routes from natural boundaries to economic activities and to identify the central hubs in the global coal supply chain based on the most recent available statistics for 2011 as the economic value and environmental influences of different kinds of coals could be remarkably diverse the separation of coal categories in systematic analysis could provide fundamental information regarding the displacement and teleconnection of coal utilization in the world the estimation shows that in weight 64 99 of coal direct supply is ultimately embodied in international trade indicating the crucial roles of trade interlinks in global coal utilization apart from this the findings pertinent to sectoral structure regional supply chain and per capita characteristics of coal embodied utilization could be valuable to identify the global energy routes driven by international trade as well as to facilitate energy and environmental policy

how strong are bequest motives evidence based on estimates of the demand for life insurance and annuities this paper presents new empirical evidence in support of the view that a significant fraction of total saving is motivated by the desire to leave bequests specifically i find that social security annuity benefits significantly raise life insurance holdings and depress private annuity holdings among elderly individuals these patterns indicate that the typical household would choose to maintain a positive fraction of its resources in bequeathable forms even if insurance markets were perfect evidence on the relationship between insurance purchases and total resources reinforces this conclusion

how inheriting affects bequest plans we present and test the idea that bequest planning is linked with the experience of inheriting we consider a family tradition of bequeathing as a channel through which the intention to bequeath is moulded by and is positively correlated with the experience of inheriting using data from the survey on health ageing and retirement in europe share we find that the experience of inheriting enhances the intention to bequeath independently of the positive impact of wealth we also find that the expectation of inheriting has a positive impact on the intention to bequeath controlling for the expected increase in wealth on account of future inheritances

bequest behavior and the effect of heirs earnings testing the altruistic model of bequests that parents transfer resources to children because of altruistic concern is a reasonable a priori assumption however economic theories of altruistic transfers have produced many counterintuitive conclusions and consequently much debate when applied to bequests these theories predict that inheritances will compensate for earnings differences between siblings as well as between parents and children this paper tests these implications using a new data set centered on federal estate tax returns little support can be found for an altruistic theory of bequests this finding has implications for macroeconomic policy government transfer programs and inequality copyright 1996 by american economic association

equal bequests and parental altruism compatibility or orthogonality abstract the large amount of equal division of bequests by parents who otherwise would have compensated the earning differences among their children is attributed to the cost associated with unequal bequests this paper identifies a source of this cost and explains why equal bequests to children whose earnings differ and parental altruism toward these children are not mutually exclusive

making the transition to prepaid medicare the medicare system is facing a financial crisis brought on by a combination of factors 1 a financing system that relies on intergenerational transfers from workers to the elderly as its major source of revenue 2 a payment scheme that traditionally has provided neither the demand nor the supply side of the market with strong incentives to hold down costs and 3 the penchant of congress to expand the coverage of the system over time every time a worthy cause or group can be identified the expansion of medicare benefits began almost immediately after the passage of the legislation in 1967 just one year after medicare had passed congress increased the number of days of in patient hospital care covered by the program in 1972 payment for the services of interns and residents in podiatry training was added to the benefit package also medicare coverage was extended to disabled persons under age 65 who were eligible for benefits under social security or railroad retirement and to certain other individuals under age 65 suffering end stage renal disease later medicare benefits were extended to state and local government employees not covered by social security and then coverage was extended to spouses of workers who were not yet covered but would be eligible to be covered in 1980 unlimited home health visits were covered as was the use of alcohol detoxification facilities in 1985 medicare provided payment for liver transplant services 1 there is current political pressure to

diagnosis murder the death of state death taxes since 1976 more than 30 states have eliminated their death taxes and many others have reduced them this unexplored case of interstate tax competition presents a unique opportunity to develop a new more satisfying definition of competitor based on historical elderly migration patterns using data from 1967 onward we outline the recent history of state death tax competition and present a spatial econometric analysis interstate tax competition is evident and grows stronger when using migration based definitions of competitors the article concludes with still more evidence of interstate tax competition the recent movement by states to effectively revive their death taxes jel h7 d7 i introduction the federal estate tax has received wide attention especially because its elimination has been a centerpiece of president george w bush s tax proposals 1 largely overlooked however is the quiet revolution that has been taking place at the state level since 1976 31 of the 48 contiguous states have repealed their death or estate inheritance and gift eig taxes instead relying only on the pick up tax whereby states capture a portion of the federal estate tax liability but do not increase the overall liability of the estate 2 of the remaining 12 states that still have eig taxes 2 have enacted legislation that will eliminate them by 2005 and others are considering doing so beyond the outright elimination of eig taxes many states have also acted to reduce them in a variety of ways such as exempting certain beneficiaries such as the spouse this trend is noteworthy for several reasons foremost it appears to us a prime example of intense interstate tax competition due to the growing size and political influence of the elderly population there is additional political pressure because states may worry that high eig taxes will drive the high income elderly to move to bordering states or retirement havens the stakes may be substantial for example longino and crown 1989 estimate that florida had a net gain of 5 billion in income from the elderly migrants it received between 1985 and 1990 and sastry 1992 73 estimates that one new job is created for every 2 5 elderly migrants it receives state eig tax competition also provides us with a unique opportunity to explore alternative definitions of competitor states beyond simple geography because the movements of the tax base the elderly are fairly easy to track via historical migration data yet no research to our knowledge has explored interstate eig tax competition furthermore these widespread changes in state eig taxes provide substantial cross sectional and time series variation that has been mostly overlooked by researchers interested in the behavioral effects of estate taxes 3 state eig tax policy is also still in flux current and proposed changes in the federal estate tax have substantial revenue consequences for states effectively eliminating eig tax revenues for those that rely solely on the pick up tax how will the states react to this change at present several states have enacted or are considering legislation that would effectively decouple their eig taxes from the federal estate tax and so would preserve the revenue source indeed as the federal estate tax is slowly eliminated eig taxes in states that continue to use them may be the only remaining taxes on bequests yet little is known about them our research seeks to fill this void using state level data from 1967 to the present we first describe the brief history and geographical pattern of these widespread reductions in state eig taxes to our knowledge ours is the first research to document in a systematic way this phenomenon we begin with a chronology of the states that eliminated completely their eig taxes thereby choosing to rely instead only on the pick up tax however there are many other ways that the states may reduce their eig taxes such as increasing exemptions or reducing tax rates

an overview of energy consumption of the globalized world economy abstract for the globalized world economy with intensive international trade an overview of energy consumption is presented by an embodied energy analysis to track both direct and indirect energy uses based on a systems input output simulation in 2004 the total amounts of energy embodied in household consumption government consumption and investment are 7749 874 and 2009 mtoe million tons of oil equivalent respectively the united states is shown as the world s biggest embodied energy importer 683 mtoe and embodied energy surplus receiver 290 mtoe in contrast to china as the biggest exporter 662 mtoe and deficit receiver 274 mtoe energy embodied in consumption per capita varies from 0 05 uganda to 19 54 toe rest of north america based on a forecast for 2005 2035 china is to replace the united states as the world s leading embodied energy consumer in 2027 when its per capita energy consumption will be one quarter of that of the united states

diverse beliefs survival and the market price of risk we study prices and allocations in a complete markets pure exchange economy in which there are two types of agents with different priors over infinite sequences of the aggregate endowment aggregate consumption growth evolves exogenously according to a two state markov process the economy has two types of agents one that learns about transition probabilities and another that knows them we examine allocations the market price of risk and the rate at which asset prices converge to values that would be computed under the assumption that all agents know the transition probabilities cogley and sargent 2008 showed that market prices of risk would be high in an economy with a risk neutral bayesian representative agent who learns about the parameters of a transition matrix for aggregate consumption growth starting with a pessimistic prior in 1933 1 this article studies the robustness of that finding to a per turbation that adds a small fraction of agents who know the parameters of the trans ition matrix traders participate in a walrasian equilibrium in which they do not infer information from prices grossman 1981 23 under what we assume to be the true data generating mechanism the survival of the fittest force analysed by blume and easley 2006 causes the more knowledgeable agents influence on equilibrium prices to grow over time along with their wealth we study how quickly that dissipates the effects of the initial pessimism of the less informed agents on equilibrium prices 4 to give the survival mechanism a large scope to moderate the effects of initial pessim ism we assume complete markets that allow agents to make trades of claims to wealth that are motivated solely by the different subjective probabilities they put on future states that gives the agents many opportunities to place bets that over time stochastically increase the share of wealth of the traders who know transition probabilities we solve a pareto problem to compute competitive equilibrium prices and alloca tions thereby implicitly defining an initial allocation of wealth we study how the market price of risk evolves as a function of the relative pareto weight on the better informed agent among other things we want to know how large the pareto weight on

to own or not to own your life insurance policy abstract life insurance proceeds are generally subject to the estate tax an exception is when the policy is owned by the beneficiaries and the insured gives up ownership and control including the ability to change beneficiaries should the insured strategically own the policy contract and potentially subject proceeds to estate and inheritance taxes or relinquish control with the beneficiaries owning the policy and escape such transfer taxes this paper addresses how the estate tax influences the choice of life insurance ownership using samples of estate tax returns the empirical evidence suggests that those facing high estate tax rates are more likely to forgo ownership and have proceeds excluded from their estates and provides further evidence on the incentive effect of taxes and in support of the strategic bequest motive

stock market wealth and consumer spending martha starr mccluer this article investigates the effects of stock market wealth on consumer spending traditional macroeconometric models estimate that a dollar s increase in stock wealth boosts consumption by three to seven cents with the substantial 1990s rise in stock prices the nature and magnitude of this wealth effect have been much debated after describing the issues and previous research i present new evidence from a well known consumer survey the results are broadly consistent with life cycle saving and a modest wealth effect most stockholders reported no appreciable effect of stock prices on their saving or spending but many mentioned retirement saving in explaining their behavior jel e21 e30 d12 i introduction the relationship between stock market wealth and consumer spending has been a subject of long standing interest traditional macroeconometric models estimate that a dollar s increase in household wealth boosts consumer spending by three to seven cents per year such an effect is consistent with predictions from a simple life cycle model in which consumers spend more over their lifetimes in response to higher wealth however the stock market is known to play a role as a passive predictor of information thus it is also possible that stock prices simply lead aggregate economic activity without any short run change in spending induced by changes in wealth understanding the response of spending to changes in wealth is important for determining how stock market fluctuations affect the macroeconomy the question also bears directly on theories of saving behavior and on the issue of retirement preparedness by today s workers the experience of the past few years provides an interesting opportunity to revisit this issue stock prices increased substantially in the 1990s with the standard poor s 500 more than doubling from 1994 to 1997 and rising another 44 through 1999 at the same time stock ownership broadened considerably mostly through mutual funds and retirement accounts so that a large number of households likely experienced wealth gains the increase in wealth might be expected to boost consumer spending and lower the saving rate and indeed these trends occurred however it is hard to separate the influence of the wealth effect from other factors that also would have promoted spending such as strong income growth and favorable labor market conditions this article presents some new evidence on the response of spending to changes in wealth the data come from the michigan survey research center src survey of consumers an ongoing nationally representative survey of u s households in interviews conducted between july and september 1997 households owning stock were asked special questions about their spending and saving the questions covered a number of factors that may influence the effect of wealth on spending including the value and form of stockholdings stock price expectations concerns about retirement and perceptions of income uncertainty in brief the results are broadly consistent with life cycle saving and a modest wealth effect the vast majority of stockholders reported no appreciable effect of stock prices on their spending or saving but many mentioned retirement saving in explaining their behavior the next section reviews previous research on the relationship between stock market wealth and consumer spending the third section describes the data from the michigan survey and the fourth presents the results a final section summarizes and concludes ii background and previous research to frame the discussion it is useful to review how an unexpected increase in wealth would affect consumption in a simple lifecycle model this model though restrictive in its assumptions provides valuable intuition about the propensity to consume unexpected stock gains consequences of refinements to the model are discussed below

bequest taxes inter vivos gifts and the bequest motive abstract this paper investigates the existence of an operative bequest motive by testing whether state bequest taxes influence the giving of inter vivos gifts a significant positive relation between bequest tax rates and both the probability and level of inter vivos gifts is found suggesting that at least some portion of bequests is intentional

global primary energy use associated with production consumption and international trade presented in this study is a comprehensive analysis for energy use of different economic entities in global supply chains including the exploiter producer consumer intermediate trader and final trader the systems input output analysis method is adopted to trace the direct and indirect energy use associated with both intermediate production and final consumption activities in the economic system in the world economy 15 of the energy use embodied in trade turns out to be induced by final consumption and 85 is attributed to intermediate production different trading patterns for different economies are identified with the separation between energy trade for intermediate production and that for final consumption for japan with a production oriented trading pattern intermediate trade should be a top priority in local trade structure adjustment while final trade needs more attention for the government in the united states as the country is in a consumption oriented trade pattern this analysis aims to provide an in depth insight into energy sustainability as well as a sound scientific reference for policy making at the regional national and global scale

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

planned and unplanned bequests we distinguish between bequests that are planned as part of a lifetime optimization process and those that are the unplanned result of errors in forecasting the date of death given the initial endowment we expect a positive relation between the bequest and the planning horizon and a negative relation between unexpectedly long life and the bequest a unique data set on wealthy decedents and their parents provides measures of expected horizons based on parents longevity both predictions are confirmed and there is an especially large and significant positive relation between the bequest and the length of the planning horizon

an overview of mercury emissions by global fuel combustion the impact of international trade abstract this study provides an overview of mercury emissions by global fuel combustion by compiling the detailed inventory as well as elaborating the impact of international trade based on the global fuel related mercury emissions inventory covering 26 sectors in 186 economies for the year of 2010 systems multi region input output analysis is employed for the first time to investigate international trade s impact on mercury emissions induced by each economy the estimated mercury emissions mainly contributed by coal burning are 859 12 t approximately 30 of which are embodied in commodities transported to consumers in other economies via international trade the emerging economies such as mainland china and india are the prominent net exporters of embodied mercury emissions while developed economies like japan germany and the usa are the net importers indicating that developed economies avoided a large amount of direct mercury emissions by transferring the production of emission intensive commodities to developing economies by integrating the direct emissions and the net trade effect mainland china has the largest embodied mercury emissions followed by the usa and india this study verifies the significant role of international trade in drawing a holistic picture of global fuel related mercury emissions the findings also suggest that focusing on the atmospheric mercury pollution directly emitted by local producers in isolation may result in an absurd situation of regional reduction at the cost of global rise it is anticipated that the current study provides insights for forming a reasonable emission responsibility sharing mechanism and facilitating comprehensive abatement strategies

the market organism long run survival in markets with heterogeneous traders abstract the information content of prices is a central problem in the general equilibrium analysis of competitive markets rational expectations equilibrium identifies conditioning simultaneously on contemporaneous prices and private information as the mechanism by which information enters prices here we look to the ecology of markets for an explanation of the information content of prices markets could select across traders with different beliefs or reminiscent of the wisdom of crowds markets could balance the diverse information of many participants we provide theoretical support in favor of the first mechanism and against the second along the way we demonstrate that the necessary condition for long run survival in complete markets found in sandroni 2000 do markets favor agents able to make accurate predictions econometrica 68 6 1303 1342 and in blume and easley 2006 if you re so smart why aren t you rich belief selection in complete and incomplete markets econometrica 74 4 929 966 is not sufficient for long run survival we also demonstrate some surprising behavior of market prices when several trader types with different beliefs survive this paper continues the research program of blume and easley 1992 evolution and market behavior journal of eonomic theory 58 1 9 40 and beker and chattopadhyay 2006 consumption dynamics in general equilibrium a characterisation when markets are incomplete university of warwick unpublished

investment and bilateral insurance abstract private information may limit insurance possibilities when two agents get together to pool idiosyncratic risk however if there is capital accumulation bilateral insurance possibilities may improve because misreporting distorts investment we show that if one of the pareto weights is sufficiently large that agent does not have incentives to misreport this implies that under some conditions the full information allocation is incentive compatible when agents have equal pareto weights in the long run either one of the agents goes to immiseration or both agents lifetime utilities are approximately equal the second case is only possible with capital accumulation

energy perspective of sino us trade imbalance in global supply chains abstract the unprecedented global supply chain fragmentation brings an ever increasing trade imbalance in terms of monetary flows between china and the united states associated with the bilateral trade imbalance is the reallocation of resources utilization and environmental stress in this regard this study presents an embodied energy model to investigate impacts of sino us trade imbalance on global energy use during 2000 2014 distinguished from previous studies that only evaluate the sino us trade based on specific bilateral perspective this study probes into overall impacts of the sino us trade on global primary energy use pattern from the perspective of global supply chains for the first time a boost to eastbound trade and distinct export industrial structures fuel the unprecedented growth of sino us embodied energy trade imbalance accounting for more than half of the total energy transfers embodied in sino us trade such imbalance firstly increases sharply from 1956 0 pj in 2000 to 5265 3 pj in 2006 followed by a short term decrease to hit a low point at 3267 7 pj in 2009 because of financial crisis and then a gradual resuscitation with a slower pace in the following years the exported energy embodied in manufacturing products dominates eastbound flows whereas energy embodied in agricultural products technology intensive products and primary energy commodities constitute majority of westbound flows due to the dispersed production process in global value chains more than half of primary energy use embodied in the bilateral trade is geographically exploited in other economies along the supply chain i e europe the middle east and south asia furthermore security of energy supply is evaluated for the two economies the results can help predict potential influences of trade conflicts on global energy extraction illustrating policy implications to make sino us trade in line with global energy conservation goals considering sino us trade s impacts along complex supply chains distinctive domestic energy conservation measures should give way to global collective and inclusive governance

consumption dynamics in general equilibrium a characterisation when markets are incomplete we introduce a methodology for analysing infinite horizon economies with two agents one good and incomplete markets we provide an example in which an agent s equilibrium consumption is zero eventually with probability one even if she has correct beliefs and is marginally more patient we then prove the following general result if markets are effectively incomplete forever then on any equilibrium path on which some agent s consumption is bounded away from zero eventually the other agent s consumption is zero eventually so either some agent vanishes in that she consumes zero eventually or the consumption of both agents is arbitrarily close to zero infinitely often later we show that a for most economies in which individual endowments are finite state time homogeneous markov processes the consumption of an agent who has a uniformly positive endowment cannot converge to zero and b the possibility that an agent vanishes is a robust outcome since for a wide class of economies with incomplete markets there are equilibria in which an agent s consumption is zero eventually with probability one even though she has correct beliefs as in the example in sharp contrast to the results in the case studied by sandroni 2000 29 and blume and easley 2006 8 where markets are complete our results show that when markets are incomplete not only can the more patient agent or the one with more accurate beliefs be eliminated but there are situations in which neither agent is eliminated c 2010 elsevier inc all

bequest motives social security and economic growth junxi zhang this article conducts a systematic analysis of four bequest motives in a simple model of endogenous growth it analyzes how bequest motives affect fertility savings growth and the effects of pay as you go social security it is found that altruistic and exchange motives give equivalent outcomes if the discount factors are set the same the outcome under the joy of giving motive may involve a higher bequest ratio higher saving and better growth rates than that under altruism if bequests are accidental the equilibrium values will depend on the probability of survival moreover the results provide testable implications on bequest motives jel d1 d9 h55 j1 i introduction although the importance of bequests in aggregate savings has been established by kotlikoff and summers 1981 who reported that 80 of u s household wealth is inherited wealth what bequest motives lead to inheritance remains an unsolved problem yet it is well known that bequest motives have important implications for the behavior of financial markets the macroeconomic impacts of fiscal policies and the intergenerational transmission of inequality in the distribution of wealth at least four hypotheses for the existence of bequests have been discussed in the literature 1 bequests may arise from intergenerational altruism that is parents obtain utility from their heirs utility as well as from their own consumption barro 1974 2 the prospect of bequests is used by parents to induce children to behave as desired by parents bernheim et al 1985 3 bequests may arise from the joy of giving that is parents leave bequests simply because they obtain utility directly from the bequest yaari 1964 1 and 4 bequests may be the unintentional by product of precautionary savings and a stochastic date of death in the absence of an annuity market abel 1985 following barro 1974 and becker 1974 the altruistic bequest motive has been used most frequently however the enormous empirical work using micro data has not led to conclusive evidence on the one hand bernheim et al 1985 cox 1987 and cox and rank 1992 show that bequests are more consistent with exchange than altruism altonji et al 1992 1997 also show that altruism is decisively rejected moreover wilhelm 1996 finds little support for an altruistic theory of bequests on the other hand a recent reexamination of the exchange motive by perozek 1998 shows that the finding of bernheim et al is not robust laitner and juster 1996 find some evidence of altruistic bequests therefore a definite conclusion on bequest motives seems far from over indeed though altruism has not been supported by most of those empirical studies it remains a plausible hypothesis and continues to be used frequently see e g coate 1995 and davies and zhang 1995 abel 1985 argues theoretically that although the simple life cycle model without bequest motives is an inadequate description of the savi ng behavior in the united states as found in kotlikoff and summers 1981 accidental bequests by selfish consumers can account for a sizable fraction of aggregate wealth however little formal empirical work has been done to test whether bequests are accidental or arise from joy of giving given the lack of consensus on bequest motives it is interesting to conduct a systematic theoretical analysis of different bequest motives in a particular context becker et al 1990 and caballe 1995 assume altruism in their models of economic growth wiedmer s 1996 analysis of social security and growth does not consider bequests except ihori 1994 there seems to be no analysis of other bequest motives in the context of economic growth the purpose of this article is to analyze how different bequest motives affect fertility savings and economic growth the article will also examine how the effects of pay as you go social security depend on bequest motives

intergenerational transfers and the accumulation of wealth h t ouseholds acquire wealth from two sources they save out of income they have earned and they receive transfers from other people the first method of wealth accumulation goes under the name of life cycle saving in which people save during their working lives and dissave after retirement the second involves either an inter vivos transfer that is a transfer between living people or a bequest a transfer that occurs at the death of the donor while inter vivos transfers and bequests will arise in dynastic models where preferences include a taste for the well being of one s descendents few empirical life cycle models reflect these concerns indeed a sharp debate has arisen over the ability of the simple life cycle model to explain observed wealth accumulation understanding the relative sizes of these sources of wealth accumulation affects a variety of issues for example the effects of government debt social insurance public transfer programs estate taxes and incentives for charitable giving depend to some extent on the magnitude and nature of private saving and transfers of wealth analyses of the inequality of wealth may depend on whether most of wealth is earned or received as transfers appropriate policies for encouraging private saving may look rather different depending on whether most saving is to be consumed later in life or passed along to the next generation finally evidence on transfer patterns relates to more fundamental

choosing between gifts and bequests how taxes affect the timing of wealth transfers abstract a number of theories have been advanced to explain the size and timing of intergenerational transfers one factor only recently explored is the effects of taxes and in particular the estate tax on such transfers this paper represents the first attempt to explore how capital gains and gift taxes in addition to the estate tax interact to influence incentives in the timing of transfers using estate tax data and exploiting variations in state inheritance gift and capital gains tax rates this paper finds taxes to be an important consideration in the choice between gifts and bequests in particular each of capital gains and gift taxes are found to be important determinants of the timing of transfers these findings are robust to a number of specifications that control for borrowing charitable bequests marital status and the portfolio composition of wealth transfers
