bequests gifts and social security this paper analyses the very long run or stationary state impact of an unfunded social security system we use an overlapping generations model framework a key feature is that while parents care about their children and can leave non negative bequests to them children also care about their parents and can make non negative gifts to them we show that the possibility of negative net bequests may make social security less harmful to private wealth accumulation than would otherwise be the case a subsidiary finding is that risk loving behaviour may emerge for some households due to the nature of intergenerational transfers within family lines

optimal social security in a dynastic model with investment externalities and endogenous fertility this paper studies optimal pay as you go social security with investment externalities positive bequests and endogenous fertility with an investment externality a competitive solution without social security suffers from under investment in capital and over reproduction of population we show the existence of time consistent optimal social security that improves welfare by reducing fertility and increasing capital intensity we also illustrate numerically that a small degree of this externality can justify the observed high ratios of social security spending to gdp

public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

heterogeneity redistribution and the friedman rule we study monetary models with nondegenerate stationary distributions of money holdings we find that the friedman rule does not typically maximize ex post social welfare an increase in the rate of growth of the money supply has two effects the standard distortionary or rate of return effect makes money a less desirable asset for all moneyholders a second redistributive effect creates a transfer from one type of agent to the other an increase in the rate of growth of money away from the friedman rule can produce a rate of return effect that dominates the standard effect

long run effects of unfunded social security with earnings dependent benefits this paper examines the effects of unfunded social security with bequests fertility and human capital by considering a mix of earnings dependent and universal social security benefits we show that social security is more likely to promote growth by reducing fertility and increasing human capital investment if its benefits are more dependent on individuals own earnings through simulations we find that the differences in the effects of social security resulting from variations in the benefit formula can be too substantial to be ignored we also investigate the welfare effect in calibrated economies c 2003 elsevier b v all rights reserved

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

health investment saving and public policy this paper develops an overlapping generations model in which agents invest in health to prolong life in both working and retirement periods it explores how unfunded social security with or without health subsidies affects life expectancy economic growth and welfare in particular by extending life at a possible cost of capital accumulation health subsidies and a pay as you go pension can improve welfare especially in the short run

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

aggregate and distributional effects of fair social security abstract in an overlapping generations economy with production endogenous labor supply a bequest motive and uncertain lifetime we show that a fair fully funded social security program reduces the aggregate levels of output employment capital and savings we determine the necessary and sufficient conditions for this social security program to increase the inequality of the income distribution the conclusions apply to the entire non stationary competitive equilibrium path taken by the economy following the introduction of social security

distributional effects of public education in an economy with public pensions we study how the allocation of government expenditures between two major outlays education and pay as you go social security affects human capital distribution in an economy with heterogeneous agents we consider an overlapping generations economy where the government maintains both programs and allocates tax revenues to finance them in our model human capital is one of the factors of production it is itself produced as a combined result of public inputs and private inputs parents decisions to invest time and material resources in education of their children are motivated by altruism heterogeneous in its strength across the population which leads to heterogeneity of incomes we investigate the effect of an increase in public funding for education on the human capital distribution we show that in this framework contrary to some earlier results increased spending on public education may lead to higher inequality our results depend crucially on the interaction of education funding with the social security budget and on the elasticity of substitution in the learning technology

social security public education and the growth inequality relationship abstract we study how the relationship between economic growth and inequality depends upon the levels of funding of two of the largest government programs public education and social security we do this in the context of an overlapping generations economy with heterogeneous agents where the government collects a tax on labor income to finance these programs we show that in our model an increase in government spending on social security reduces income inequality and can have a non monotonic effect on growth when the initial level of social security funding is low as is the case in most poor economies then its increase will enhance growth when its funding level is high as is typical for developed countries we show that its further increase can slow down growth while reducing income inequality these results obtain regardless of whether the increase in social security funding is financed by a tax increase or by cutting the public education budget we also find that the effects of increasing the level of public education expenditures or the overall size of the government budget holding the budget composition fixed are characterized by similar non monotonic growth inequality relationships

the evolution of modern educational systems technical vs general education distributional conflict and growth abstract we study the evolution of an educational system founded on a hierarchical differentiation between vocational and general education with vocational playing an inferior role in the society the dynamics are best summarized by the ratio of the fraction of the population in vocational to that in general education which we interpret as a measure of the degree of stratification of the society we show that this ratio first rises and then declines with the level of development displaying an inverted u shape which reflects the complex interaction between economic and political forces including aggregate income growth wealth inequality and political participation

public pensions and growth abstract this paper investigates the relationship between the size of an unfunded public pension system and economic growth in an overlapping generation economy in which altruistic parents finance the education of their children and leave bequests unlike the existing literature we model intergenerational altruism by assuming that children s income during adulthood is an argument of parental utility unfunded public pensions can promote growth when families face liquidity constraints preventing them from investing optimally in the education of their children we consider two alternative ways of financing a public pension system either by levying social contributions in a lump sum manner or in proportion to labour income we find that there is no case for unfunded public pensions in economies where bequests are operative by contrast there exists a growth maximising size of the public pension system in economies where bequests are not operative and individuals are sufficiently patient

socially optimal social security and education subsidization in a dynastic model with human capital externalities fertility and endogenous growth abstract this paper considers socially optimal government policies in a dynastic family model with physical capital human capital endogenous fertility and positive spillovers from average human capital such spillovers reduce human capital investment but raise fertility from their social optimum we first characterize the social optimum with a non convex feasible set due to the quantity quality tradeoff concerning children we then show that social security and education subsidization together financed by labor income taxes can fully eliminate the efficiency losses of the spillovers and achieve the social optimum under plausible conditions however none of the policies can do so alone

the distribution of money balances and the nonneutrality of money recent monetary models with explicit microfoundations are made tractable by assuming that agents have access to centralized markets after one round of decentralized trade given quasi linear preferences this makes the distribution of money degenerate which keeps the models simple but precludes the discussion of distributional effects of monetary policy we generalize these models by assuming two rounds of trade before agents can readjust their money holdings to study a range of new distributional effects analytically we show that unexpected symmetric lump sum money injections may increase short run output and welfare whereas asymmetric injections may increase long run output and welfare

the allocation of public funds in a hierarchical educational system abstract this paper studies the dynamic effects of allocating public funds between basic and advanced education holding the size of total public education funds fixed i identify the effects of their composition on aggregate efficiency and in equality first since basic education is a prerequisite for attending advanced education there exists a lower bound on funding it allocation policies below this lower bound are strictly pareto dominated whether a corresponding lower bound on funding advanced education exists or not depends on the development stage of the economy and the size of total public funds secondly while an allocation policy favoring basic education generates the usual redistribution from top to bottom one favoring advanced education may result in reverse redistribution from bottom to top last through the inter generational link short run allocation policies may have long run effects a simple rule of thumb is that for an economy in its early development stage focusing on basic education for sufficiently long duration is the only way out of polarization and low aggregate efficiency contrary to the actual policies pursued by many of the less developed economies

efficient monetary allocations and the illiquidity of bonds abstract we construct a monetary economy with heterogeneity in discounting and consumption risk agents can insure against this risk with money and nominal government bonds but all trades must be monetary we demonstrate that a deflationary policy a la friedman cannot sustain the constrained efficient allocation as no arbitrage imposes too stringent a bound on the return money can pay the constrained efficient allocation can be sustained when bonds have positive yields and under certain conditions only if they are illiquid illiquidity meaning that bonds cannot be transformed into consumption as easily as cash is necessary to eliminate arbitrage opportunities due to disparities in shadow interest rates

corruption fertility and human capital abstract we build an overlapping generations model in which reproductive households face a child quantity child quality trade off and bureaucrats are delegated with the task of delivering public services that support the accumulation of human capital by integrating the theoretical analyses of endogenous growth corruption and fertility choices we show that the negative relation between fertility and economic development may also be affected by differences in the magnitude of bureaucratic corruption

a divisible search model of fiat money this paper extends the kiyotaki wright search model of fiat money to allow for divisible money and goods the extension allows me to examine the standard issues in monetary economics such as the neutrality and superneutrality of money by severing the artificial link in the kiyotaki wright model between the money supply and the number of money holders it is shown that money is neutral but not superneutral money growth generates a trading opportunity effect it changes the fraction of different agents in the economy and hence changes the probability with which agents have a successful match in addition money growth has a negative effect on the real money balance that is familiar in walrasian monetary models the balance of the two effects can imply a positive optimal money growth rate

specification of the joy of giving insights from altruism this paper analyzes the joy of giving bequest motive in which the utility obtained from leaving a bequest depends only on the size of the bequest it exploits the fact that this formulation can be interpreted as a reduced form of an altruistic bequest motive to derive a relation between the value of the altruism parameter and the value of the joy of giving parameter using previous discussions of an a priori range of plausible values for the altruism parameter we then derive plausible restrictions on the joy of giving parameter we demonstrate that this parameter may well be orders of magnitude larger than assumed in the existing literature this abstract was borrowed from another version of this item

aggregation of heterogeneous time preferences we examine an economy whose consumers have different discount factors for utility possibly not exponential we characterize the properties of efficient allocations of resources and of the shadow prices that would decentralize such allocations we show in particular that the representative agent has a decreasing discount rate when as is usually posited all of a group s members have a constant discount rate and decreasing absolute risk aversion preferences we also identify conditions that lead the representative agent to have a rate of impatience that decreases with gross domestic product per capita

optimal social security in a dynastic model with human capital externalities fertility and endogenous growth abstract in this paper we investigate the optimal scale of pay as you go social security in a dynastic family model with human capital externalities fertility and endogenous growth human capital externalities reduce the return to human capital investment and hence lead to under investment in human capital and over reproduction of the population if the taste for the number of children is sufficiently weak relative to the taste for the welfare of children social security can be welfare enhancing by reducing fertility and raising human capital investment per child

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

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

social security and individual welfare precautionary saving borrowing constraints and the payroll tax this paper examines the impact of social security on national saving and individual welfare in the presence of realistic capital market imperfections market failure in the private provision of annuities and restrictions on borrowing against anticipated future wages the introduction of social security increases lifetime welfare and reduces national saving if borrowing restrictions are absent however the increase in individual welfare is reduced and in some cases eliminated when borrowing constraints are taken into consideration the substantial difference suggests the importance of reexamining the proportional payroll tax finance of social security copyright 1987 by american economic association

public budget composition fiscal de centralization and welfare we study the optimal degree of fiscal decentralization in a dynamic federal economy where governments decide on budget size and its allocation between public education and infrastructure spending we find that full centralization of tax and expenditure policies is optimal when infrastructure productivity is similar across regions when differences are not too large partial centralization is optimal with strong differences full decentralization becomes optimal national steady state output tends to be highest under full decentralization we provide a justification for the mixed evidence regarding the oates conjecture by showing that full dominates partial decentralization despite being inferior to complete decentralization on etudie le degre optimal de decentralisation fiscale dans une economie federale dynamique ou les gouvernements decident de la taille du budget et de son allocation entre les depenses en education publique et en infrastructures on decouvre qu une pleine centralisation des taxes et des depenses est optimale quand la productivite des infrastructures est la meme dans toutes les regions quand les differences ne sont pas trop importantes une centralisation partielle est optimale en presence de fortes differences la pleine decentralisation est optimale la production nationale en regime permanent tend aetre la plus elevee quand il y a pleine decentralisation on fournit une justification pour les resultats mixtes obtenus quant a la conjoncture de oates en montrant que la pleine decentralisation est preferable a la decentralisation partielle meme si elle est inferieure a la decentralisation complete

the effects of compulsory schooling on growth income distribution and welfare abstract in this paper we consider an olg model with productive capital and human capital affecting the quality of labor in each generation parents invest in their children s education but disregard its external effect on the aggregate production function government intervention in providing compulsory schooling increases economic growth along the equilibrium path while the intragenerational income distribution becomes more equal also in the long run the majority of individuals in each generation are better off due to compulsory schooling

uncertainty and optimal social security systems this paper examines the annuity aspect of social security within the framework of an overlapping generations model the duration of life is assumed to be uncertain under a fully funded system demand for social security is determined by each generation so as to maximize expected lifetime utility taking into account the welfare of future generations under a pay as you go system with intergenerational transfers demand for retirement benefits by the working population takes into account taxes paid by descendants it is shown that the two modes of finance are equivalent in terms of all real aggregates effects of changes in expected lifetime and in the birth rate are analyzed starting at the optimal level a compulsory balanced increase in social security taxes and benefits is shown to increase short run savings

public schooling college subsidies and growth abstract how does the mix of public education expenditures across primary and secondary k 12 education and post secondary college education influence economic growth to address this i build an overlapping generations endogenous growth model human capital is accumulated through compulsory k 12 education and through optional college education government uses tax revenue to provide quality in k 12 schooling and to subsidize college tuition when total expenditures are small all funds should provide k 12 quality when expenditures are above a critical value a positive share should subsidize tuition the share should increase with total expenditures and with the degree of complementarity of human capital accumulated through the two types of education also increased education spending is more likely to increase growth when a larger share subsidizes tuition

education choice endogenous growth and income distribution this paper studies an economy where parents can choose between public or private schools and can vote on taxes used to fund public schools the model is calibrated to us data and studied using simulations a bimodal income distribution emerges where public education students converge to a low income equilibrium while private education students experience endogenous growth with higher incomes however public education students experience long run growth through a spillover from private education students possible problems with the existence of a private alternative to pubic education such as the emergence of a education based class structure are identified

education social security and growth abstract we study the role of government s allocation of tax revenues between two outlays public investment in education a transfer to the young generation and social security benefits to the older generation in an overlapping generations economy with pay as you go social security and altruistically motivated transfers from parents to children we analyze how the allocation of the tax revenues between the two outlays affects growth and welfare in competitive equilibria a we obtain comparative dynamics results for nonstationary equilibria subject to a change in the allocation profile b for stationary equilibria we show that for a given allocation profile of the tax revenues educational subsidies can either increase the growth rate or decrease it depending on the parameters of the model preferences production function and the tax rate c if government seeks to allocate funds in a way that maximizes the growth rate we demonstrate that under some plausible conditions it is not optimal to maintain pay as you go social security however if parents preferences combine strong concern for their retirement with significant degree of altruism towards their children then pay as you go social security system does enhance growth and welfare

the role of intergenerational transfers in aggregate capital accumulation this paper uses historical u s data to directly estimate the contribution of intergenerational transfers to aggregate capital accumulation the evidence presented indicates that intergenerational transfers account for the vast majority of aggregate u s capital formation only a negligible fraction of actual capital accumulation can be traced to life cycle or hump savings a major difference between this study and previous investigations of this issue is the use of more accurate longitudinal age earnings and age consumption profiles these profiles are simply too flat to generate substantial life cycle savings this paper suggests the importance of and need for substantially greater research and data collection on intergenerational transfers life cycle models of savings that emphasize savings for retirement as the dominant form of capital accumulation should give way to models that illuminate the determinants of intergenerational transfers

optimal monetary policy in an economy with incomplete markets and idiosyncratic risk abstract this study investigates an incomplete markets economy in which the saving behavior of a continuum of infinitely lived agents is influenced by precautionary saving motives and borrowing constraints agents can use two types of assets interest bearing ious and money to smooth consumption money is valued because of a timing friction in the bond market in particular the bond market closes before agents observe their idiosyncratic productivity shock i find that the friedman rule is not optimal for this economy the results indicate that the optimal allocation has a rate of inflation of 10 and a positive amount of private credit held by the government a positive inflation rate transfers resources from agents with big endowments to those holding bonds which improves risk sharing and therefore welfare however for higher rates of inflation agents economize on money holdings offsetting the insurance effects and causing a reduction in welfare furthermore higher rates of inflation discourage agents from borrowing and the endogenous lower bound on bond holdings is higher than the exogenous borrowing limit high rates of inflation therefore exacerbate frictions in the bond market

uncertain lifetimes and the welfare enhancing properties of annuity markets and social security this paper explores the implications of social security programs and annuity markets through which agents who are characterized by different distributions of length of lifetime share deathrelated risks when annuity markets operate a non discriminatory social security program affects only the intragenerational allocation of resources in the absence of private information regarding individual survival probabilities such a program will lead to a non optimal intragenerational allocation of resources however the presence of adverse selection considerations gives rise to a pareto improving role for a mandatory non discriminatory social security program

endogenous determination of public budget allocation across education stages abstract this paper studies the endogenous determination of public budget allocation across hierarchical education stages in less developed economies the top class has dominant political power to implement its most preferred policy which is characterized by exclusive participation and large schooling expenditure at higher education at the expense of basic education in developed economies the budget allocation is more balanced under certain parameters it leads to expanded participation of the middle class in higher education the model offers an explanation to the observed cross country policy difference and is broadly consistent with historical evidence

endogenous fiscal policy and capital market transmissions in the presence of demographic shocks abstract previous analyses of population aging mainly focused on the social security implications of the aging trend this paper addresses aging in an open economy framework with two regions that have politically responsive fiscal policy regarding education finance demographic shocks start an economic growth process but results are sensitive to a critical parameter in the model that indicates return to education spending low values of this parameter are associated with less favorable economic outcomes hence a policy implication emerges that enhancing the education system might pay off in terms of easing the negative growth and welfare consequences of expected demographic shocks

heterogeneity and redistribution by monetary or fiscal means in models with heterogeneous agents issues of distribution and redistribution jump to the fore raising the question which policies monetary or fiscal work most effectively in transferring income from one group to another to begin answering this question this note works through a series of examples using townsend s turnpike model two basic results emerge first the zero lower bound on nominal interest rates often appears as an obstacle to redistribution by monetary means second assumptions made about the government s ability to raise tax revenue without distortion and to discriminate between agent types in distributing that tax revenue play a large role in determining whether agents prefer to redistribute income by monetary or fiscal means

two sided intergenerational transfer policy and economic development a politico economic approach we consider an overlapping generations model with public education and social security where the overall size of these policies is determined in a repeated voting game we investigate the interaction between the politically determined policies and economic development in a markov perfect equilibrium the following results are obtained first the level of human capital determines whether these policies are sustained in the markov perfect equilibrium second if the level of initial human capital is sufficiently high human capital grows forever in contrast if the level of initial human capital is low the economy might be caught in a poverty trap

against posner against coase against theory in two articles published in 1993 richard posner characterized and vigorously attached ronald coase s methodological orientation coase resisted posner s diagnosis but did not provide a response this paper offers a response which coase might have given one of posner s major claims was that coase is antitheoretical or hostile to theory here it is suggested that posner s allegations suffer from serious unreflected ambiguities once we distinguish between a few different meanings of theory and theoreticity and between attitudes and accomplishments in regard to theory or between being antitheoretical nontheoretical protheoretical and theoretical it becomes possible to argue that coase does not hold an antitheoretical attitude even if his accomplishments fall short of theory in many but not all senses of the word the larger relevance of this conflict is that its confusions tend to be characteristic of parts of the economics profession more widely copyright 1998 by oxford university press

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

optimal public investments in education and endogenous growth optimal public investments in human capital through subsidizing private education or providing public education are considered in an endogenous growth model with externalities subsidizing private education stimulates growth improves welfare and has no distributional effect while reducing income inequality as in the literature public education hinders the growth of the average income unless externalities are strong enough and reduces the welfare of the median agent unless initial income inequality is sufficiently high societies with high income inequality may provide public education and will replace it with subsidized private education in some future periods as income converges copyright 1996 by the editors of the scandinavian journal of economics

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

money is memory abstract this paper examines the sets of feasible allocations in a large class of economic environments in which commitment is impossible following myerson 8 the standard definition of feasibility is adapted to take account of the lack of commitment the environments feature either memory or money memory is defined as knowledge on the part of an agent of the full histories of all agents with whom he has had direct or indirect contact in the past money is defined as an object that does not enter utility or production functions and is available in fixed supply the main proposition is that any allocation that is feasible in an environment with money is also feasible in the same environment with memory depending on the environment the converse may or may not be true hence from a technological point of view money is equivalent to a primitive form of memory journal of economic literature classification numbers e40 c73 d82

public versus private investment and growth in a hierarchical education system abstract the paper studies the interaction between public and private spending in a two stage education framework k 12 and tertiary education and their effects on economic growth we find that an increase in the overall education public spending crowds out the total level of private contributions and increases the share of resources that households devote to k 12 education for a given public budget a higher share of k 12 public funding induces higher private education spending overall of which a larger share goes towards higher education the model broadly matches data on education finance in the oecd countries the calibrated parameter values suggest that at both stages public and private inputs are good yet imperfect substitutes with a higher degree of complementarity in basic education we show that the growth maximizing share of public spending devoted to k 12 should be high irrespective of the size of the public budget using the calibrated model to compare the structure of education funding in the eu and the us we find that to maximize growth high tax countries should use more of their public resources in tertiary education relative to low tax countries this suggests that us efforts to improve k 12 education and the reform of higher education in europe are consistent with the objective of increased economic growth

funded social security and economic growth abstract this paper investigates the relationship between economic growth and a fully funded social security system in an overlapping generations model with family altruism it is shown that funded social security may harm growth if there are operative bequests within the family

sequential markets and the suboptimality of the friedman rule a cash in advance model with sequential markets is constructed where unanticipated monetary injections are nonneutral and can potentially produce large liquidity effects however if the monetary authority adheres to an optimal money rule money should not respond to unanticipated shocks so that a friedman rule is suboptimal and the monetary authority does not exploit the liquidity effect quantitatively the model can generate variability in money and nominal interest rates close to what is observed and can produce data with no obvious evidence of the existence of liquidity effects

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

public education expenditures taxation and growth linking data to theory governments around the world have taken a prominent role in financing education while justifications for this involvement are varied a common motivation is that education expenditures are a key to sustained economic growth economic theory provides a foundation for this belief many papers in the endogenous growth literature have formalized a link between public education expenditures human capital accumulation and long term growth while theory assigns public education expenditures a key role in growth empirical support for the link is mixed as highlighted by blankenau and simpson 004 the disconnect between theory and data can be reconciled by taking a closer look at the theory in nearly every model where growth is fueled by public education expenditures a nonmonotonic relationship between expenditures and growth can arise public education spending increases growth while taxes may decrease growth leaving the net effect ambiguous thus economic theory shows that to identify the growth effects of expenditures one must account for any offsetting effects of the requisite taxation most empirical investigations of these effects do not explicitly control for the method of finance however in contrast we make the relationship between expenditures taxation and growth central to our analysis we estimate a

educational systems growth and income distribution a quantitative study this study sets out to develop a dynamic model within an economy characterized by the coexistence of public and private schools under imperfect credit market conditions in an attempt to provide a clearer understanding of the evolution of economic growth and income inequality we find that any government wishing to reduce income inequality should adopt policies aimed at increasing the enrollment rate in public schools however whilst high enrollment rates can be sustained in private schools and thus create enhanced economic growth this can only occur if accompanied by the liberalization of the credit markets
