the deadweight loss from non neutral capital income taxation abstract this paper develops an overlapping generations general equilibrium model that treats explicitly the role of capital goods in the production process and uses the model to measure the relative magnitudes of different distortions associated with capital income taxation across industries assets and time one of the main results is that uniform capital income taxation is almost certainly suboptimal theoritically but that optimal deviations from uniform taxation are empirically inconsequencial the paper also introduces and applies a general technique for distinguishing intergenerational transfers from efficiency gains in the analysis of the impact of policy changes on long run welfare

examining the relationship between visual attention and stated preferences a discrete choice experiment using eye tracking abstract we examine the relationship between visual attention and stated preferences derived from a discrete choice experiment focussing on consumer preferences regarding country of origin food labels we employ a bayesian infinite mixture logit to derive results that reveal patterns of respondent heterogeneity that would not be captured assuming that random parameters take a specific distributional form our results reveal weak relationships between the eye tracking data our stated preference results and various attribute use questions although respondents with higher levels of visual attendance value specific attributes more highly the strength of the relationship is fairly weak therefore whilst we maintain that eye tracking is useful we argue that there needs to be greater clarity about the aims and purpose of using eye tracking in stated preference research

does the public sector over provide club goods a general result abstract with nondistortionary user charges the first best and second best of a single club exogenous income economy with identical individuals coincide they differ if incomes differ overprovision of a superior club good then occurs in the second best

time is money time pressure incentives and the quality of decision making many decisions in economics and finance have to be made under severe time pressure furthermore payoffs frequently depend on the speed of decision making as for instance when buying and selling stocks in this paper we examine the influence of time pressure and time dependent incentive schemes on the quality of decision making in an experimental beauty contest game we find that convergence to equilibrium is faster and payoffs are higher under low time pressure than under high time pressure interestingly time dependent payoffs under high time pressure lead to significantly quicker decision making without reducing the quality of decisions

the long run causal relationship between transport energy consumption and gdp evidence from heterogeneous panel methods robust to cross sectional dependence abstract this paper employs panel methods that address mitigate heterogeneity and cross sectional dependence to determine the direction and sign of long run causality between transport energy consumption per capita and real gdp per capita granger causality was determined to run from gdp to energy

does financial development have a non linear impact on energy consumption evidence from 30 provinces in china abstract this paper uses a sample of 30 provinces in china for the period 1997 2017 to examine the relationship between financial development and energy consumption based on the traditional convergence hypothesis this paper constructs a functional convergence model and explores the dynamic convergence of energy consumption the results show that there is a significant threshold effect between financial development and energy consumption there is an inverse u shaped relationship between foreign investment ratio financial efficiency and energy consumption besides financial interrelations ratio and insurance depth increase energy consumption the trend of china s energy consumption tends to be consistent in the eastern region the growth rate of energy consumption is negatively correlated with the initial level there is only a convergence effect on energy consumption in the central region however the difference in energy consumption in the western region is continually expanding

pigou meets mirrlees on the irrelevance of tax distortions for the second best pigouvian tax this paper extends the mirrlees 1971 model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities using general utility structures and exploring both linear and non linear taxes it is demonstrated that the optimal second best tax on an externality generating good should not be corrected for the marginal cost of public funds since it equals one in the optimal tax system in the optimum distortions of income taxes are equal to marginal redistributional gains if the government does not have access to a non distortionary marginal source of finance the marginal cost of public funds can be either larger or smaller than one depending on subjective preferences for income redistribution the optimal second best corrective tax is then either higher or lower than the pigouvian level the findings in this paper generalize and amend prior results based on representative agent models shedding new light on the weak double dividend hypothesis and on the welfare gains of recycling revenue from environmental taxes

lottery choice incentives complexity and decision time this paper reports the results of an experiment on lottery choice in which decision cost is measured as decision making time a simple decision cost model motivates this measurement and the experiment and predicts relationships between incentive mechanism manipulations and decision making time which are borne out in the experiment the decision cost model also suggests that decisions will change in the face of the incentive manipulations in the experiment this suggestion is borne out in a complex decision making environment but not in a simple one specification tests demonstrate that observed changes in subjects behavior are not merely due to changes in subject specific error variance one may conclude from this that the payoff dominance problem is a real issue in complex decision making experiments copyright 1993 by royal economic society

distortionary taxes and the provision of public goods economists have long been concerned with finding an efficient level of public expenditure the classic statement of the problem was given by paul samuelson 1954 an optimal level of expenditure is where the sum of the marginal rates of substitution between the public good and a reference good equals the marginal rate of transformation between the public good and the reference good mrs mrt however samuelson s formula assumes that all of the revenue needed to finance public goods can be raised with lump sum taxes since this is not generally possible the formula must be modified to account for the distortionary effects of the tax system an appropriate modification is to multiply the cost side of the equation by a term that is commonly called the marginal cost of public funds mcf in the case of samuelson s formula where government is entirely financed with lump sum taxes the mcf would be exactly 1 0 in the traditional view of economists distortionary taxes cause the mcf to be greater than one thus raising the cost of providing public goods in this paper we discuss some cases where the mcf may be less than one we will illustrate this possibility using numerical examples for labor taxes

two sector perspectives on the effects of payroll tax cuts and their financing abstract this paper analyzes the consequences of lifting from labor some of the burden of taxation in a life cycle two sector setup where a consumption good is produced alongside a capital good the analysis focuses on the implications of alternative ways of financing payroll tax cuts in closed and small open neoclassical economies in our models payroll tax cuts do not necessarily stimulate hours worked in the stationary state we show for example that in the closed economy paradoxically long run aggregate labor hours and the capital stock will be reduced if labor tax proceeds are replaced by capital taxation if instead government purchases of the capital good or government labor services are decreased manhours are left unchanged in the long run while capital formation is spurred in the small open economy it is only if the offsets are a fall in entitlement spending or a rise in the wealth tax that aggregate manhours are increased otherwise steady state hours worked are invariant

nature of transfers income tax function and empirical estimation of elasticity of taxable income for brazil abstractthis article aims to estimate the elasticity of taxable income eti taking into account the nature of transfers and their use as a redistribution package involving cash and in kind transfers to households in brazil our contributions are twofold first we provide a simple model with balanced budget government that reveals the role played by cash and in kind transfers on the labour supply and income tax revenues thereof next in order to estimate eti in the presence of cash and in kind transfers brazilian population surveys pesquisa nacional por amostra de domicilios pnad are used to explore a limited tax reform that was implemented between 1997 and 1998 this reform only affected the higher income tax bracket our findings suggest that in kind cash transfers are positively negatively associated with reported taxable income and precise estimation of eti requires estimates of both types of transfers last we estimate the eti for brazil in the range from 0 4 to 1 3 not different fro

the dual process drift diffusion model evidence from response times we introduce a model of response time and choice that borrows from two distinct psychological traditions as in dual process models rapid automatic decisions are qualitatively different from considered decisions as in the drift diffusion model delayed considered decisions occur when confidence hits a threshold level we conduct a simple experiment in which our hybrid model matches key properties of the data as our model predicts decision times are bimodal automatic decisions are of far lower quality than considered decisions and automatic decisions are more prevalent when prior information improves thereby raising their quality jel d83 d87 c91

status effects public goods provision and excess burden abstract most studies of the optimal provision of public goods or the excess burden from taxation assume that individual utility is independent of other individuals consumption this paper investigates public good provision and excess burden in a model that allows for interdependence in consumption in the form of status relative consumption effects in the presence of such effects consumption and labor taxes no longer are pure distortionary taxes but have a corrective tax element that addresses an externality from consumption as a result the marginal excess burden of consumption taxes is lower than in the absence of status effects and will be negative if the consumption tax rate is below the pigouvian rate correspondingly when consumption or labor tax rates are below the pigouvian rate the second best level of public goods provision is above the first best level contrary to findings from models without status effects for plausible functional forms and parameters relating to status effects the marginal excess burden from existing u s labor taxes is substantially lower than in most prior studies and is negative in some cases

marginal welfare costs of taxation with human and physical capital i introduction marginal welfare cost of taxation is the amount by which the social cost of an additional tax dollar differs from 1 because of distortionary taxation browning and johnson 1984 stuart 1984 browning 1987 ballard 1988 and allgood and snow 1998 use static models of the u s economy in which labor supplies adjust but the stocks of human and physical capital are fixed to calculate estimates of this welfare cost relevant to cost benefit analysis the studies by lucas 1990 and perroni 1995 incorporate human and physical capital into calculations of excess burden for the purpose of comparing alternative tax systems but do not address the welfare costs of marginal tax and spending reforms ballard et al 1985 and judd 1987 provide estimates of welfare cost using models that allow the stock of physical capital to change in response to marginal reforms but the stock of human capital is exogenous in these studies however judd 2001 argues that there is ample evidence indicating that human capital investment decisions have a significant effect on the cost of altering the tax system which suggests that these decisions could also have an important influence on marginal welfare cost in this article we present estimates of welfare costs for marginal reforms to government tax and spending policies when labor supply saving and education decisions are all endogenous we focus our analysis on marginal reforms because as skinner and slemrod 1985 observe most policy reforms enacted do not involve replacing one tax or spending system with another but instead typically entail marginal adjustments in tax laws and government appropriations using a perfect foresight overlapping generations model with a three period life cycle we derive analytical expressions for the changes in labor supply saving and education and use them to calculate marginal welfare cost as shown by auerbach et al 1983 in overlapping generations models steady state welfare comparisons of alternative tax policies are biased unless households are compensated for intergenerational redistribution along the transition path to arrive at our steady state estimates of welfare costs we adapt the compensation method introduced by gravelle 1991 for analyzing fundamental tax reforms to the context of incremental tax and spending reforms in a static one consumer model triest 1990 has shown that marginal welfare cost mwc is positive solely because of tax leakage the decline in tax revenue caused by reductions in the tax base we extend this insight to an intertemporal context that incorporates tax leakage arising from changes in both human and physical capital investment we evaluate three sets of reforms first a revenue neutral reduction in the tax on capital income funded by a higher tax on labor income second spending on a public good financed by either a higher tax on labor or interest income third a per capita lump sum transfer or demogrant also funded by either a higher tax on labor or interest income we find that marginal welfare costs are uniformly lower in the dynamic model where investment decisions are endogenous than in the static model where investment decisions are fixed and that the majority of the difference between the dynamic and static estimates is attributable to human capital decisions the principal reason is that a reallocation of time between labor hours and human capital investment has opposing and potentially offsetting effects on effective labor supply as a result labor supply responds less elastically in the dynamic model and changes in labor supply are the main source of tax leakage because wage taxation is the main source of tax revenue we also find that shifting marginal financing from capital to labor results in a lower welfare cost the reason being that such a change encourages saving which increases wage rates and stimulates labor supply leading to a reduction in marginal welfare costs

public goods self selection and optimal income taxation using the self selection approach to tax analysis this paper derives a modified samuelson rule for the provision of public goods when the government deploys an optimal nonlinear income tax this approach gives a straightforward interpretation of the central result in this area generalises it and provides a simple characterisation of optimal policy in a wide range of circumstances the analysis also emphasises and clarifies the significance of the choice of numeraire for the optimality of decentralising public spending decisions it is well known that the famous samuelson rule for the provision of public goods may not be applicable when the tax revenues used to finance the public goods come from distorting taxes the principle was recognized as long ago as pigou 1947 long before the samuelson rule was devised pigou saw that in addition to the resource cost involved in transferring funds from the private to the public sector there was a deadweight loss involved from this insight he suggested that the criterion for providing public goods should be more stringent than the samuelson rule would later suggest in particular one might expect that the inclusion of the deadweight loss of taxes as part of the cost of providing a public good would lead to a reduction in its optimal provision relative to a situation in which lump sum taxes were available the problem was investigated more systematically by atkinson and stern 1974 who considered the case in which a public good is financed by a set of optimal commodity taxes all individuals were assumed to be identical so efficiency alone dictated the objective they found that no prima facie case could be made for the pigou position that the use of distortionary taxes called for a reduction in the supply of the public good their analysis clearly showed that there were two influences at work when the financing of a public good was by distorting taxes on the one hand

taxes in a life cycle growth model with bequests and inheritances in a recent paper lawrence summers 1981 analyzes alternative taxes in a life cycle growth model this paper extends his analysis to include bequests and inheritances this inclusion is worth undertaking for several reasons first several recent empirical studies have suggested that bequests may account for an important share of the capital stock laurence kotlikoff and summers 1981 second it is important to explore whether the comparison of taxes is significantly affected when a bequest motive is introduced third the treatment of bequests under a consumption tax is controversial the endowment rationale calls for treating a bequest as taxable consumption by the deceased peter mieszkowski 1980 the real wage rationale calls for exempting bequests if such exemption raises the steady state capital intensity and real wage my 1980 article this paper confines itself to positive analysis of steady states transition paths and normative implications are explored elsewhere see my 1982 paper

economic growth and transport energy consumption in the latin american and caribbean countries abstract transport is a strategic sector for economic development whilst being one of the most polluting sectors of the economy the latin american and caribbean countries have been consolidated as the region with significantly faster energy consumption growth this paper analyzes how the gdp per capita affects the transport energy consumption testing possible non linear relationships between variables a transport energy consumption function depending on gdp and its squared and cubed value is estimated for 22 lac countries over the period 1990 2014 the results support an n shaped curve while the elasticity values of transport energy consumption with respect to gdp per capita do not show a tendency to decrease in the long term fourteen lac countries show absolute coupling levels at the end of the period while the rest exhibit partial couplings likewise trade openness population density degree of urbanization and structural changes in the economy have positive effects on the transport energy consumption this paper proposes some energy efficiency measures to control the growing energy use and the promotion of biofuels and electric vehicles is also considered necessary to reduce the negative effects of transport energy use

neuroeconomic foundations of economic choice recent advances neuroeconomics combines methods and theories from neuroscience psychology economics and computer science in an effort to produce detailed computational and neurobiological accounts of the decision making process that can serve as a common foundation for understanding human behavior across the natural and social sciences because neuroeconomics is a young discipline a sufficiently sound structural model of how the brain makes choices is not yet available however the contours of such a computational model are beginning to arise and given the rapid progress there is reason to be hopeful that the field will eventually put together a satisfactory structural model this paper has two goals first we provide an overview of what has been learned about how the brain makes choices in two types of situations simple choices among small numbers of familiar stimuli like choosing between an apple or an orange and more complex choices involving tradeoffs between immediate and future consequences like eating a healthy apple or a less healthy chocolate cake second we show that even at this early stage insights with important implications for economics have already been gained

the allocation of time in decision making we study the allocation of time across decision problems if a decision maker 1 has noisy estimates of value 2 improves those estimates the longer he or she analyzes a choice problem and 3 allocates time optimally then the decision maker should spend less time choosing when the difference in value between two options is relatively large to test this prediction we ask subjects to make 27 binary incentive compatible intertemporal choices and measure response time for each decision our time allocation model explains 54 of the variance in average decision time these results support the view that decision making is a cognitively costly activity that uses time as an input allocated according to cost benefit principles

a testable theory of imperfect perception we provide a new characterization of bayesian expected utility maximization the novel feature of the model is our separation of actions from prizes the signature of the resulting theory is the impossibility of raising utility by switching wholesale from one action to another we provide applications to robustness to the recovery of utility from choice data and to model

a sectoral approach balancing global efficiency and equity this paper explores the idea that a properly designed sectoral approach could be the answer to two sets of constraints that hinder international agreements on climate change namely a genuine concern from developing countries for economic growth and competitiveness issues from industrialized countries our sectoral approach builds on three premises i cap and trade systems are established in industrialized countries and intensity targets in developing countries ii sectors subject to international trade abide by the rules of the countries in which they trade and iii a fraction of the revenues from permits in industrialized countries go towards carbon mitigation in developing countries we design an economic model that features interactions in three carbon intensive sectors two of which are internationally traded and two countries an industrialized country and a developing country two scenarios are constructed an enhanced sectoral approach which refers to our proposal and a global cap which implements a uniform co2 price we compare the two scenarios in terms of total welfare and equity it is shown that for a minor global welfare loss the enhanced sectoral approach ranks high in terms of equity for emerging countries this approach also eliminates competitiveness and leakage issues

redistribution and the marginal cost of public funds abstract discussions of the marginal cost of public funds with distortionary taxation are often cast in the framework of a one consumer economy while the main justification of distortionary taxes is that they are needed for redistribution this paper analyzes the issue in a model with heterogeneous consumers and a linear income tax focusing on the tradeoff between labour market distortions and the redistribution from high wage to low wage workers in an optimal tax system the mcf will be the same for all sources of funds and under certain assumptions less than one without optimality the mcf will in general differ between different sources of finance

property taxation congestion and local public goods abstract the residential property tax has been viewed as a congestion fee even if it distorts housing decisions this paper shows that the rule for a competitive jurisdiction s optimal public good supply may be written in a form in which no such role appears congestion costs enter the cost side of this rule in the same way that they enter when only a land tax is available the new rule is reconciled with an alternative rule in the literature which contains no congestion costs

welfare and optimum dynamic taxation of consumption and income abstract this paper estimates that the us could attain large welfare gains by implementing an optimal ramsey tax policy that taxes consumption and income it is also found that the welfare implications associated with taxing consumption are quantitatively more important than those associated with dynamically taxing income indeed replacing income taxes with a constant consumption tax leads to a welfare gain that is only slightly lower than that attained by a dynamic policy that taxes consumption and income in computing these welfare gains careful attention is given to the dynamic path of tax rates and the transitional dynamics associated with how the economy responds to a new tax policy

a marginal cost of funds approach to multi period public project evaluation implications for the social discount rate abstract although the use of marginal cost of funds mcf has been widely appreciated in public finance literature discussions of mcf have been confined to a static setting this paper develops a multi period project evaluation rule that is based on mcf unlike previous approaches the parameters required for implementing the mcf rule are independent of projects under consideration a lesson from this paper is that the government discount rate policies that are largely based on the concepts of social discount rate and shadow price of capital should be rewritten with the use of parameters representing mcf

optimal public good provision with limited lump sum taxation it is often argued that the use of distortionary taxation lowers the optimal provision of public goods below its optimal level in a first best economy which contains no restrictions on lump sum taxation however this issue is usually investigated using commodity tax models that contain no lump sum taxes this paper examines a many consumer economy in which the only tax instruments are commodity taxes and a poll tax subsidies are negative taxes the optimal level of public good provision in this economy typically exceeds the first best level at least for distributionally neutral public goods copyright 1991 by american economic association

when do distortionary taxes reduce the optimal supply of public goods abstract it is often argued that the optimal level of public good provision is below the first best level as long as the government s expenditures have to be financed by distortionary taxes i examine this hypothesis and show that it is correct in a representative consumer economy if i the public good is normal and ii private commodities are normal and gross substitutes otherwise counterexamples can be constructed these results hold also with heterogeneous households provided that equity considerations are ignored in general however distributional objectives may lead to a higher level of public expenditures in second best than in first best

decision time consideration time and status quo bias economists increasingly appreciate the value of studying the time taken to make decisions in order to provide insights into decision makers choices this article shows that studying how time is allocated among individual options is also valuable in helping researchers to understand the impact default options have on decision makers attention allocation as approximated by how the time is allocated the study of this impact generates new insights into the well known choice phenomenon of status quo bias which typically refers to decision makers tendency to stick to a default option by designing a series of novel experiments i find that this bias arises even when the choice is among prizes of fixed monetary value expressed in arithmetic form i also find asymmetric attention i e more time devoted to default options and strikingly asymmetric choice errors specifically decision makers fail to select an alternative better than the default 28 of the time while they incorrectly select an alternative worse than the default only 11 of the time and provide evidence supporting a causal relationship between asymmetric attention and asymmetric errors jel d03 d12 d83

measuring energy rebound effect in the chinese economy an economic accounting approach estimating the magnitude of china s economy wide rebound effect has attracted much attention in recent years most existing studies measure the rebound effect through the additional energy consumption from technological progress however in general technological progress is not equivalent to energy efficiency improvement consequently their estimation may be misleading to overcome the limitation this paper develops an alternative approach for estimating energy rebound effect based on the proposed approach china s economy wide energy rebound effect is revisited the empirical result shows that during the period 1981 2011 the rebound effects in china are between 30 and 40 with an average value of 34 3

when is efficiency separable from distribution in the provision of club goods abstract using the homogeneous of degree zero inverse congestion quality function employed most frequently in the literature we characterise completely the families of utility functions which are then necessary and sufficient for break even utilitarian welfare maximising provision of club goods with self selection to be separable from distribution two types of separation involving alternatively a the price and quality b the price quality facility size and total utilisation are considered when separation is possible utility functions and optimal decisions take simple intuitive forms our results extend the scope of separation results previously obtained only for pure public goods journal of economic literature classification numbers d62 h23 h40

discounting according to output type federal discount rate policies advocate both a high rate representing the marginal productivity of capital and a low rate representing the government borrowing rate these differential discount rate policies could be inconsistent and biased in favor of projects on which the lower discount rate is applied this paper shows that the coexistence of different discount rates may be appropriate depending on the type of project output when a project s outputs are perfect substitutes for private consumption both its costs and benefits should be discounted using the marginal productivity of capital however if the project s outputs are separable in the utility function the benefits should be discounted using the net of tax rate of return

tax analysis in a real business cycle model on measuring harberger triangles and okun gaps abstract a tax distorted real business cycle model is parameterized calibrated and solved numerically in an attempt to measure the size of harberger triangles relative to okun gaps in particular the model constructed is used to study quantitatively the impact of various distortional government tax and subsidy schemes it is shown that the government can use tax policy to stabilize cyclical fluctuations and this is done for the economy being studied the benefits of implementing such a stabilization policy are calculated and compared with the size of the welfare gains realized from reducing various tax distortions

is public spending good for you the whole world is marching towards the right with the transformation of the soviet union and eastern europe the drastic economic reforms in china and the privatisation liberalisation and reversing the historical increasing trend reduction in public spending in many western countries 1 much about these changes is applaudable and economists may feel proud for partially contributing to them however this paper argues that the reduction in public spending especially in education research and environmental protection is counter productive this may not be so viewed in the narrow perspective of production and consumption especially in the short run but is almost certainly so viewed in the wider perspective of welfare or happiness in the long run it is well known that public spending has some efficiency problems but the probably much worse inefficiency of private consumption has been largely ignored this paper attempts to provide a broader and more balanced picture from an interdisciplinary perspective

the efficiency gains from dynamic tax reform this paper presents a new simulation methodology for determining the pure efficiency gains from tax reform along the general equilibrium rational expectations growth path of life cycle economies the principal findings concern the effects of switching from a proportional income tax with rates similar to those in the u s to either a proportional tax on consumption or a proportional tax on labor income a switch to consumption taxation generates a sustainable welfare gain of almost 2 percent of lifetime resources in contrast a transition to wage taxation generates a loss of greater than percent of lifetime re sources a second general result is that even a mild degree of progressivity in the income tax system imposes a very large efficiency cost this abstract was borrowed from another version of this item

social accounting and the public sector this article contributes to the theory of social accounting as such it tries to extend earlier literature on the welfare equivalence of the comprehensive net national product in two main directions both of which refer to the public sector one is by considering welfare measurement problems associated with public good provision and redistributive policy respectively when the public revenues are raised by distortionary taxes the other is by addressing the consequences of a federation like decision structure where independent tax and expenditure decisions are made both by the central government and by lower level governments

does urbanization lead to less energy use and lower co2 emissions a cross country analysis despite the relationship between urbanization energy use and co2 emissions has been extensively studied in recent years little attention has been paid to differences in development stages or income levels most previous studies have implicitly assumed that the impact of urbanization is homogenous for all countries this assumption can be questionable as there are many characteristic differences among countries of different levels of affluence this paper investigates empirically the effects of urbanization on energy use and co2 emissions with consideration of the different development stages using the stochastic impacts by regression on population affluence and technology stirpat model and a balanced panel dataset of 99 countries over the period 1975 2005 the findings suggest that the impact of urbanization on energy use and emissions varies across the stages of development surprisingly urbanization decreases energy use in the low income group while it increases energy use in the middle and high income groups the impact of urbanization on emissions is positive for all the income groups but it is more pronounced in the middle income group than in the other income groups these novel findings not only help advance the existing literature but also can be of special interest to policy makers and urban planners

imperfect competition the marginal cost of public funds and public goods supply abstract this paper analyses the impact of changes in product market competition on the marginal cost of public funds mcpf and public goods supply when distortionary commodity taxes are used to raise revenue first less competition measured by a switch from bertrand to cournot conduct or a decrease in the elasticity of demand does not necessarily raise the mpcf second even if it does optimal public good supply does not necessarily fall the paper also presents a method for modelling bertrand and cournot competition in general equilibrium that may be of independent interest

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

equity effects of the tax reform act of 1986 the major goals of the tax reform act of 1986 included an increase in the equity of the tax system but equity is a concept that is difficult to evaluate one dimension of equity involves vertical equity the idea that people of different income should be treated differently by the tax code this notion is often closely linked with the idea that the tax code should be at least somewhat progressive the tax reform act has also been characterized as favoring lower income individuals relative to higher income ones six million lowincome families were removed from the tax roles through increased standard deductions and personal exemptions and the earned income tax credit which refunded taxes to low income workers was expanded a second dimension of equity is horizontal equity the attempt to be sure that individuals with equal incomes are treated equally the tax reform act took many steps toward equalizing the treatment of different types of income it converted the personal tax rate schedule into two rates eliminated longstanding tax benefits such as the investment tax credit and the capital gains exclusion curtailed recently enacted incentives such as accelerated depreciation and individual retirement accounts struck deeply at popular tax shelters cut the top marginal tax rate for individuals by over one third and reduced the corporate tax rate by over one quarter but although efficiency gains have been

income consumption and wage taxation in a life cycle model separating efficiency from redistribution the desirability of switching from an income tax base to a wage or consumption tax base hinges critically on the potential efficiency gains from doing so the overlapping generations life cycle model developed by lawrence summers 1981 cannot easily be used to answer this question because individuals of different ages alive at the time of the tax substitution differ in their shares of income consumption wages and savings propensities steady state welfare changes include redistribution of taxes and factor incomes the effects of redistribution on the calculation can be controlled for by tracing the transition in another paper summers 1980 used myopic expectations individuals assume that current prices will prevail and solved the economy s equilibrium for 100 years gains and losses were discounted and summed alan auerbach laurence kotlikoff and jonathan skinner 1983 hereafter referred to as aks employed a perfect foresight model they used lumpsum payments to keep the utility of those alive at the time of the tax change fixed and allowed equal equivalent variations to all future generations 1 a perfect foresight model requires simultaneous solution of many years of equilibria 150 years in the aks model although these techniques eliminate distributional elements such models are so costly to construct modify and use that the study of relative efficiency of alternative tax regimes is now greatly hampered by computational complexity this study has two major contributions first it introduces a much simpler method of separating the efficiency and redistributional components of steady state gains rather than tracing the transition it uses a system of transfers which ensures that changes in welfare in the steady state do not arise from redistribution of income to or from transitional generations while this approach does not allow calculation of the transition its application to the aks model suggests that very little information about the magnitude of efficiency effects is lost by forgoing the tracing of the transition for estimating the relative efficiency of income consumption and wage taxation or the extent to which assumptions drive the results this approach greatly simplifies the researcher s task 2 this simplification becomes increasingly valuable as more detail is introduced into models which could involve thousands of equations using an approach that traces the transition secondly my calculations suggest that switching tax bases may not be worthwhile this result differs from the results of summers 1981 and auerbach and kotlikoff 1987 which strongly suggest that the consumption tax is always superior on efficiency grounds using a 0 25 intertemporal substitution elasticity and a cobb douglas production function the steady state wel congressional research service library of congress washington dc 20540 i thank christophe chamley don fullerton yolanda henderson don kiefer larry kotlikoff jonathan skinner tom woodward dennis zimmerman and three anonymous referees for helpful comments and discussions the views in this paper do not necessarily represent those of the congressional research service or the library of congress 1the aks model is confined to one good charles ballard 1984 1989 lawrence goulder 1985 and ballard and goulder 1987 develop multisector models 2the suggestion of a method for separating efficiency from redistribution is not intended to imply that there is no value to tracing the transition tracing the transition can provide information about intergenerational redistribution in an uncompensated change and insights into the realism of the model

changes in automobile energy consumption during urbanization evidence from 279 cities in china abstract automobile sector is one of the important parts of the transportation industry china s booming auto sector has also brought huge energy consumption and energy consumption in the automobile sector will continue to increase with the further development of china s economy urbanization is a complex process of modernization and it may be an important reason for the change in automobile energy consumption according to the current literature the impact of urbanization may exist as a positive or negative mechanism based on the sample of 279 cities in 31 provinces of china from 2003 to 2015 this paper analyzes how urbanization affects automobile energy consumption in the disparity of income and then it also further explores the heterogeneity of automobile energy consumption in different regions the conclusion of this paper shows that considering the income disparity the effect of urbanization on automobile energy consumption increased first and then decreased the regions with relatively low automobile energy consumption will gradually catch up with the high energy consumption regions and automobile energy consumption in each region will not converge to its own steady state

a generalized approach to multigeneration project evaluation 1 introductionit is well known that the choice of discount rate plays a significant role in the ranking of projects with varying time paths of costs and benefits for public projects the choice of the appropriate social discount rate sdr is not clear cut even in the context of short lived projects in which costs and benefits occur within a single generation in particular when capital taxes produce a wedge between gross and net rates of return should one discount at the economy s rate of return the before tax rate or the individual s rate of return the after tax rate in the single generation context the literature falls in two camps 1 one camp argues that the appropriate sdr is a weighted average of the gross and net rates of return with weights typically determined by the fractions of resources drawn from consumption and private investment respectively 2 a second camp argues that future benefits should be discounted at the net rate of return but that the initial investment should be multiplied by a scale factor so that the direct costs of the project can be expressed in terms of consumption units 3both approaches suffer from severe implementation problems for the first approach there is no general formula for the weights needed to calculate the sdr as a weighted average of two market rates of return dreze 1974 indeed the appropriate sdr to use is project specific stiglitz 1982 without a systematic methodology to derive project specific sdrs the weighted average approach is hard to implement for the second approach which equalizes the sdr to the net rate of return the scale factor the opportunity cost of public investment must be quantified the opportunity cost of public investment depends on whether resources come from private investment or consumption and on the calculation of the present value of the future consumption yielded by a unit of capital discounted at the net rate of return that is the shadow price of capital as lind 1997 points out however there is no general agreement on a specific procedure for calculating the shadow price of capital indeed the concept of the opportunity cost of public investment suffers the same project dependence problem as the first view of the sdr diamond 1968 multigeneration projects such as nuclear waste disposal natural resource conservation or even social security reform further complicate discount rate choice specifically intergenerational equity in addition to intertemporal efficiency plays a role in determining the appropriate social discount rate for multigeneration public project evaluation 4 as in the single generation context there are two competing views on the appropriate discount rate when evaluating multigeneration projects the descriptive and the prescriptive approaches 5the descriptive approach to discounting is a market based approach it does not rely on an explicit social welfare function swf or the pure time preference rate embedded in the swf however the descriptive approach works under the assumption that intergenerational compensation through changes in the tax debt policy is available 6 it is argued that under appropriate intergenerational compensation the market rates of return are still relevant for calculating the sdr for multigeneration project evaluation and in general the sdr should be a weighted average of the gross and net rates of return this descriptive view of setting the sdr equal to the market return appears to underlie the office of management and budget s omb adoption of 7 as the appropriate discount rate for federal programs 7the intent of the prescriptive approach is to use the social discount rate as an expression of ethical judgment on how consumption of future generations should be compared to consumption of current generations

impacts of urbanization on national transport and road energy use evidence from low middle and high income countries abstract few attempts have been made to investigate quantitatively and systematically the impact of urbanization on transport energy use for countries of different stages of economic development this paper examines the influence of urbanization on national transport and road energy use for low middle and high income countries during 1975 2005 using the stochastic impacts by regression on population affluence and technology stirpat model after controlling for population size income per capita and the share of services in the economy the main results suggest that urbanization influences national transport and road energy use positively however the magnitude of its influence varies among the three income groups changes in urbanization appear to have a greater impact on transport and road energy use in the high income group than in the other groups surprisingly the urbanization elasticities of transport and road energy use in the middle income group are smaller than those of the low income group this study not only sheds further light on the existing literature but also provides policy makers with insightful information on the link between urbanization and transport energy use at the three different stages of development

a pigovian rule for the optimum provision of public goods abstract the integrated treatment of optimal taxation and public expenditure presented here is based on the dual relationship between the prices of private goods and the quantities of public goods the conditions for optimum public good provision can be expressed as a modification of the samuelson conditions with extra terms representing a the distortionary effect of taxes on the willingness to pay for the public good and b distributional effects the former captures pigou s notion of the indirect damage caused by the need to finance public expenditure out of distortionary taxes and we call this the pigou term in certain cases a very simple benefit cost ratio for public projects emerges that is equivalent to measuring benefits as if they were taxed

cross border pollution terms of trade and welfare we construct a two good general equilibrium model of international trade for two small open economies where pollution from production is transmitted across borders governments in both countries impose emission taxes non cooperatively within this framework we examine the effect of changes in the degree of cross border pollution on nash emission taxes emission levels and welfare we do so under two scenarios when changes in cross border pollution do not affect domestic pollution non strategic and when they do strategic we also examine the effect of changes in international terms of trade on pollution and welfare when cross border pollution is non strategic

democratic public good provision this paper analyzes an overlapping generation model of redistribution and public good provision under repeated voting expenditures are financed through age dependent taxation that distorts human capital investment taxes redistribute income both across skill groups and across generations we focus on politico economic markov equilibria and contrast these with the ramsey allocation under commitment the model features indeterminate equilibria with a key role of forward looking strategic voting due to the lack of commitment to future policies the tax burden may be on the wrong side of the dynamic laffer curve moreover restrictions on government policies can in some cases be welfare improving

the brain as a hierarchical organization based on recent neuroscience evidence we model the brain as a dual system organization subject to three conflicts asymmetric information temporal hori zon and incentive salience under the first and second conflicts we show that the uninformed system imposes a positive link between consumption and labor at every period furthermore decreasing impatience endogenously emerges as a consequence of these two conflicts under the first and third conflicts it becomes optimal to set a consumption cap finally we discuss the behavioral implications of these rules for choice bracketing and expense tracking and for consumption over the life cycle jel dil d74 d82 d87 d91

resource allocation in the brain when an individual performs several tasks simultaneously processing resources must be allocated to dierent brain systems to produce energy for neurons to re following the evidence from neuroscience we model the brain as an organization in which a coordinator allocates limited resources to the brain systems responsible for the dierent tasks systems are privately informed about the amount of resources necessary to perform their task and compete to obtain the resources the coordinator arbitrates the demands while satisfying the resource constraint we show that the optimal mechanism is to impose to each system with privately known needs a cap in resources that depends negatively on the amount of resources requested by the other system this allocation can be implemented using a biologically plausible mechanism finally we provide some implications of our theory i performance can be awless for suciently simple tasks ii the dynamic allocation rule exhibits inertia current allocations are increasing in past needs and iii dierent cognitive tasks are performed by dierent systems only if the tasks are suciently important

optimal public good provision in the ramsey tax model a generalization abstract for the single consumer ramsey tax model the use of distortionary taxation to finance public good provision is shown to lower the optimal level of public good provision below its optimal value ina first best economy where lump sum taxation is available the assumptions used in the proof include a previous cobb douglas example as a special case

exclusion and moral hazard a further analysis abstract this paper examines the impact of increasing exclusion costs on the price of a shared good and establishes a simple elasticity condition which determines whether or not the price increases with the exclusion costs we correct an error in the reasoning in silva and kahn s journal of public economics 1993 52 217 235 paper on exclusion and moral hazard and construct a class of examples to show that contrary to their claim costly exclusion of non subscribers from the consumption of a non rivalrous good can result in a lower price as compared with the first best with costless exclusion

how china s urbanization impacts transport energy consumption in the face of income disparity abstract this paper estimates the transport energy consumption of 30 provinces in china from 1997 to 2011 by applying the stirpat model the relationship between urbanization and transport energy consumption using control variables such as population gdp per capita and the proportion of tertiary industry in gdp is investigated considering the disparities of income the impacts of urbanization on transport energy consumption might be distinct therefore this paper estimates the income threshold value and analyzes the effects of urbanization on transport energy consumption in the light of income differential using the panel threshold regression model based on the results some policy suggestions are offered

an alternative approach to aggregate surplus analysis abstract this paper suggests a dual to the many person applied welfare economics problem with constraints on lymp sum redistribution the dual has the property of minimizing an aggregator function over individual income transfers the properties of the aggregator are dependent upon the resource costs of redistribution and not upon the distributional preferences embodied in the social welfare function an interpretation of the dual problem in terms of consumer surplus is offered

consumption vs wage taxation and the capital levy abstract based on a representative consumer framework it has been argued that wage taxation is inferior to consumption taxation this note shows that the opposite result may emerge in a model where households are heterogeneous and where a uniform poll tax or subsidy is available

simulating fundamental tax reform in the united states this paper uses a new large scale dynamic life cycle simulation model to compare the welfare and macroeconomic effects of transitions to five fundamental alternatives to the u s federal income tax including a proportional consumption tax and a flat tax the model incorporates intragenerational heterogeneity and a detailed specification of alternative tax systems simulation results project significant long run increases in output for some reforms for other reforms namely those that seek to insulate the poor and initial older generations from adverse welfare changes long run output gains are modest

search and satisficing many everyday decisions are made without full examination of all available options and as a result the best available option may be missed we develop a search theoretic choice experiment to study the impact of incomplete consideration on the quality of choices we find that many decisions can be understood using the satisficing model of herbert simon 1955 most subjects search sequentially stopping when a satisficing level of reservation utility is realized we find that reservation utilities and search order respond systematically to changes in the decision making environment jel d03 d12 d83

a review article the case against the use of the sum of compensating variations in cost benefit analysis this paper presents a case against the use of the sum of compensating varia tions as a cost benefit test we argue that 1 the ethical judginents implied by the test are not defensible 2 positive sums of compensating variations occur without potential pareto improvements resulting in social preference reversals without simultaneous scitovsky re versals 3 when lump sum transfers are feasible a positive sum of compensating variations is necessary but not sufficient for a potential pareto improvement 4 in order to eliminate preference reversals and intransitivities all households must have almost identical quasi homothetic preferences a condition that is not satisfied in real economies
