a many good many person corlett hague tax rule abstract generalising the corlett hague rule yields an insight into the case for differentiated commodity taxation when the linear income tax is not optimal thus complementing earlier work by deaton

on measures of excess burden and their application abstract new measures of the additional excess burden of a tax reform are proposed and are shown to be useful in three key policy applications these new measures induce a unique measure of marginal excess burden meb among its interesting properties meb is uniformly zero for a proportional tax on inelastically supplied labor problems in applying the standard measures of total excess burden are demonstrated it is concluded that the induced measure of the marginal cost of funds mcf should be regarded as the most useful concept in applied tax analysis

double dividend effectiveness of energy tax policies and the elasticity of substitution a cge appraisal there is a considerable body of literature that has studied whether or not an adequately designed tax swap whereby an ecotax is levied and some other tax is reduced while keeping government income constant may achieve a so called double dividend that is an increase in environmental quality and an increase in overall efficiency arguments in favor and against are abundant our position is that the issue should be empirically studied starting from an actual non optimal tax system structure and by way of checking the responsiveness of equilibria to revenue neutral tax regimes under alternate scenarios regarding technological substitution with the use of a cge model we find that the most critical elasticity for achieving a double dividend is the substitution elasticity between labor and capital whereas the elasticity that would generate the highest reduction in carbon dioxide emissions is the substitution elasticity among energy goods

revealed social preferences of dutch political parties we measure the redistributive preferences of dutch political parties using unique detailed information from their election proposals by employing the inverse optimal tax method we calculate the political weights across the income distribution for each political party we find that all dutch political parties give a higher political weight to middle incomes than to the poor moreover the political weights of the rich are close to zero furthermore we detect a strong political status quo bias as the political weights of all political parties hardly deviate from the weights implied by the pre existing tax system we argue that political economy considerations are key in understanding these results

describing the separability properties of empirical demand systems in empirical demand analysis separability restrictions are usually imposed as maintained hypotheses the separability inflexibility of most functional forms makes parametric tests of these restrictions appear problematic we follow pudney 1981 in stressing the usefulness of a description of the separable structure of preferences underlying an estimated model and propose a non iterative method for the production of such a description an illustration with different models estimated for nine categories of goods on french aggregate time series data is presented

marginal commodity tax reforms a survey as noted 30 years ago by martin feldstein optimal taxes may be useless for practical purposes and emphasis should instead be placed on the possibility of enhancing welfare by reforming existing tax rates in this perspective marginal commodity tax reforms are gaining increasing attention due to political and economic constraints on large reforms of direct or indirect taxation in this paper we summarize the main features and results of the literature on marginal commodity tax reforms pioneered by ahmad and stern further developed by yitzhaki and thirsk and recently reinterpreted by makdissi and wodon we establish new links to other fields of research namely the literature on the use of equivalence scales and on poverty measurement we also critically examine some issues associated with the implementation of marginal tax reforms with special reference to the calculation of welfare weights and revenue effects finally we suggest directions for future research on poverty reducing commodity tax reforms

project evaluation by potential tax reform abstract shadow prices are derived for small open economies with several production sectors experiencing constant returns to scale small projects affect the balance of trade domestic prices of non traded goods and factors and sector scales only domestic prices affect welfare and only if there is not domestic price equalization generally a project s net benefits depend upon the potential tax and tariff reform made possible or necessary through the balance of trade effect border prices are right for traded goods but domestic good shadow pricing requires knowing the direction of at least one reversible available tax reform and presuming optimality with respect to available reforms

optimal taxation and cross price effects on labor supply estimates of the optimal gas tax abstract this study estimates parameters necessary to calculate the optimal second best gasoline tax most notably the cross price elasticity between gasoline and leisure prior theoretical work indicates the importance of this elasticity but despite this almost none of the prior studies of commodity taxation and none of the studies on second best environmental regulation actually estimate it using household data we find that gasoline is a relative complement to leisure and thus that the optimal gasoline tax is significantly higher than marginal damages the opposite of the result suggested by the bulk of the prior literature indeed even if there were no externalities at all associated with gasoline the optimal tax rate would still be almost equal to the average gas tax rate in the u s following this approach to estimate cross price elasticities with leisure could strongly influence estimates of optimal rates for other important commodity or pollution taxes

tax perceptions and preferences over tax structure in the united kingdom do voters know their tax liabilities accurately or do they systematically misperceive them could such misperceptions influence voters choices over alternative tax structures proposed by politicians this paper assesses the accuracy of individuals tax perceptions in the uk using micro data from the british social attitudes survey 1995 and tests an empirical model of the determinants of tax structure preferences including tax misperceptions a systematic bias towards over estimation of income and expenditure tax vat liabilities is found and individ uals tax preferences appear to be both dominated by self interest and distorted by tax misperceptions whether using a traditional utility maximisation framework or a variety of public choice frameworks economists agree that consumer voters or taxpayer voters dislike taxes taxes lower the consumption possibility set and thereby utility politicians proposing higher taxes expect to lose votes unless they can persuade voters that the utility gain from the use of those taxes will exceed the tax induced utility loss of course the extent of individuals losses will depend on their circumstances and how revenues are raised the tax structure traditional tax incidence and excess burden analyses and models of political costs associated with the tax structure hettich and winer 1984 1988 each provide guidance on the extent to which different individuals may be expected to suffer and vote differently under alternative tax structures much will depend on attitudes towards and perceptions of specific taxes especially personal income taxes and consumption taxes underlying most such analyses are two common presumptions i tax preferences are dictated by self interest and ii individuals accurately assess their tax liabilities and so make informed choices two largely independent areas of literature have challenged these assumptions first models incorporating altruism

household risk management and optimal mortgage choice the portfolio of the typical american household is quite unlike the diversie ed portfolio of liquid assets discussed in e nance textbooks the major asset in the portfolio is a house a relatively illiquid asset with an uncertain capital value the value of the house generally exceeds the net worth of the household which e nances its homeownership through a mortgage contract to create a leveraged position in residential real estate other e nancial assets and liabilities are typically far less important than the house and its associated mortgage contract the importance of housing in household wealth is illustrated in figure i this e gure plots the fraction of household assets in housing and in equities against the wealth percentile of the household poor households appear at the left of the e gure and wealthy households at the right data come from the 1989 and 1998 survey of consumer finances the e gure shows that middle class american families from roughly the fortieth to the eightieth percentile of the wealth distribution have more than half their assets in the form of housing even after the expansion of equity ownership during the 1990s equities are of negligible importance for these households 1

decentralisation and accountability in infrastructure delivery in developing countries many developing countries are experimenting with decentralisation of public service delivery to elected local governments instead of bureaucrats appointed by a central government we study the resulting implications in a theoretical model in which the central government is uninformed about local need and unable to monitor service allocations bureaucrats charge bribes for services as monopoly providers resulting in underprovision of services especially for the poor local governments are directly responsive to their citizens needs but may be subject to capture by elites effects of decentralisation on service volumes efficiency and equity are analysed under different financing arrangements for local governments the theme of the 2004 world development report is summarised by its opening paragraph too often services fail poor people in access in quantity in quality but the fact that there are strong examples where services do work means governments and citizens can do better how by putting poor people at the center of service provision by enabling them to monitor and discipline service providers by amplifying their voice in policymaking and by strengthening the incentives for providers to serve the poor problems of accountability associated with traditional modes of delivery involving centralised bureaucracies include cost padding service diversion limited responsiveness to local needs limited access and high prices charged especially to the poor 1 many developing countries have thus begun to experiment with initiatives to increase accountability of service providers by providing greater control rights to citizen groups these include decentralisation of service delivery to local governments community participation direct transfers to households and contracting out delivery to private providers and ngos the programmes include a wide range of infrastructure services water sanitation electricity telecommunications roads and social services education health and welfare programmes countries where such trends have gathered

using elasticities to derive optimal income tax rates this paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates a simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution in the general non linear income tax problem this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of mirrlees the optimal non linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution these formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters

commodity taxes and taste heterogeneity we study optimal linear commodity taxes in the presence of non linear income taxes when agents differ in skills and tastes for consumption we show that optimal commodity taxes are partly determined by a many person ramsey rule when there is taste heterogeneity within income classes the usual role of commodity taxes in relaxing incentive constraints explains the remaining part of these taxes when there is taste heterogeneity between income classes we quantify these two parts using french consumption microdata and find that commodities taxes are only shaped by many person ramsey considerations

earmarked taxation welfare versus political support abstract compared with the traditional public finance approach of a monolithic fully informed planner earmarking of taxation is less likely to be optimal if a principal agent setting is considered where taxing and spending are performed by two separate agents which are monitored by the parliament we assume that the parliament either maximizes welfare or expected votes vote maximizers are more inclined to choose earmarking but at the price of inefficiently high costs

household debt and monetary policy revealing the cash flow channel we study the effect of monetary policy on spending when households hold debt with variable interest rates when interest rates on outstanding loans vary with the short term market interest rate monetary policy has a direct and immediate effect on households expenses and disposable income if households are borrowing constrained they will respond to a shock to disposable income by adjusting their spending as a result a monetary policy induced interest rate change leads to a larger change in consumption than what is predicted by the elasticity of intertemporal substitution we examine this cash flow channel of monetary policy using administrative data on swedish households we estimate a strong and statistically significant response in spending to changes in interest expenses more specifically we estimate a marginal propensity to consume including durable consumption that is around unity or even higher in response to monetary policy induced changes in interest expenses for example highly indebted households with adjustable rate mortgages reduce consumption growth by several percentage points more in response to a one percentage point increase in the household interest rate than households with little debt or fixed rate mortgages our findings imply that monetary policy will have a stronger effect on real economic activity when households are highly indebted and have adjustable rate mortgages jel classification d14 e21 e52 g11

welfare analysis of tax reforms using household data abstract this paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households estimates are based on the equivalent income function which is money metric utility defined over observable variables this enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system equivalent income is related to measures of deadweight loss and standard errors are computed for each of the welfare measures an application to u k data for 5 895 households is given which simulates a reform that involves eliminating housing subsidies

the great mortgaging housing finance crises and business cycles this paper unveils a new resource for macroeconomic research a long run dataset covering disaggregated bank credit for 17 advanced economies since 1870 the new data show that the share of mortgages on banks balance sheets doubled in the course of the twentieth century driven by a sharp rise of mortgage lending to households household debt to asset ratios have risen substantially in many countries financial stability risks have been increasingly linked to real estate lending booms which are typically followed by deeper recessions and slower recoveries housing finance has come to play a central role in the modern macroeconomy

how robust is the uniform emissions pricing rule to social equity concerns abstract this paper examines pollution tax differentiation across industries in light of social equity concerns using theoretical and numerical general equilibrium analyses in an optimal tax framework we characterize the drivers for non uniform optimal taxes stemming from the interaction of household heterogeneity with social preferences quantitatively assessing the case of price based co2 emissions control in the u s economy we find that uniform emissions pricing is approximately optimal when social concerns are defined over inequity induced by the environmental tax the deviation from uniform emissions pricing however becomes non negligible when pollution tax rebates deviate much from optimal transfer schemes or when social concerns are defined over both policy induced impacts and inequity unrelated to environmental policy our results are robust to a number of model extensions including the stringency of the environmental target downstream vs upstream taxation pre existing distortionary taxes and parametric uncertainty in firms and households equilibrium tax responses

imperfections in the economics of public policy imperfections in markets and climate change the economics of public policy has suffered from collective amnesia we have forgotten or ignored much of the tradition of public policy in imperfect economies whose foundations were laid by james meade and paul samuelson this has been associated with a period of around two decades from the early 1980s to the early 2000s where the economics of public policy has bent to political winds and has fed arguments for government to get out of the way and leave everything to the markets to self interest and to self regulation this has manifested itself via the choice of models those which imply often directly from assumptions passive government patterns of teaching the marginalisation of public economies in imperfect economics and compartmentalisation examples in climate change where this amnesia has misled include approaches to discounting and the failure to make non marginal change central to analysis on the other hand creative application of modern public economics gives interesting results such as the possibility of making both current and future generations better off and of informed discussion complementing economic instruments there are strong formal analogies between policy on climate change and on behavioural economics indeed there seems to be great potential in the combination of these two fields jel a10 a12 d61 d62 d63

marginal tax reform externalities and income distribution the paper examines welfare improving and revenue neutral directions marginal policy reforms for an economy with nonidentical individuals and an externality that has a feedback effect on the consumption of taxed goods it considers three types of policy instruments the indirect taxes the uniform poll transfer and public abatement this extends the framework set up by ahmad and stern 1984 bovenberg and de mooij 1994 and schob 1996 the theoretical model is illustrated for a specific externality namely congestion caused by peak car transport

welfare dominance and the design of excise taxation in the cote d ivoire governments in developing countries are continuously searching for new and improved tax bases existing methods of taxation in these countries frequently fall short of meeting acceptable criteria of efficiency equity and administrative ease this paper argues that there is a compelling fiscal rationale for encouraging greater reliance on taxing the consumption of electrical and telephone et services greater emphasis on this selective commodity tax base would contribute to the achievement of taxpayer equity and would be administratively easy to impose in addition the efficiency characteristics of this form of taxation may also add to the attractiveness of the et base

energy populism and household welfare we study a cycle of subsidized energy prices and estimate its welfare impact on households in the buenos aires metropolitan region a simple framework explains its emergence in terms of the preference of a median household voter for receiving transfer gains followed by a future flow of transfer losses we evaluate actual transfers and welfare effects that a departure of prices of natural gas and electricity generation from opportunity costs since 2003 had on households and explore the impact of a way back to opportunity cost pricing

household expenditure and the income tax rebates of 2001 using questions expressly added to the consumer expenditure survey we estimate the change in consumption expenditures caused by the 2001 federal income tax rebates and test the permanent income hypothesis we exploit the unique randomized timing of rebate receipt across households households spent 20 to 40 percent of their rebates on nondurable goods during the three month period in which their rebates arrived and roughly two thirds of their rebates cumulatively during this period and the subsequent three month period the implied effects on aggregate consumption demand are substantial consistent with liquidity constraints responses are larger for households with low liquid wealth or low income

interest rate changes mortgages and consumption evidence from italy summaryusing the italian survey of household income and wealth we study whether the drop in interest rates following the great recession was associated with an increase in consumption for households with adjustable rate mortgages arm relative to those with fixed rate mortgages frm after the reduction in mortgage payments consumption of arm holders increases relative to frm but the implied marginal propensity to consume is not statistically different from zero we suggest three explanations for the weak consumption response to the income shock first cash on hand and debt heterogeneity may attenuate the consumption response second borrowers believe that the income shock was short lasting and that interest rates would likely increase in the future implying a small effect on consumption third the shock is offset partly by a reduction in income from financial assets owned by mortgagors the findings have implications for the conduct of monetary policy interventions and the credibility of the future path of interest rates pass through of monetary policy and design of the mortgage market

a model of tax reform for belgium abstract the paper deals with determining second best optima and existence conditions of pareto improving directions of tax reform for an economy experiencing keynesian unemployment i e characterised by excess supply of labour and commodities it is then tested whether these existence conditions were fulfilled in belgium in 1982 the model considers the taxation of seven consumption goods plus labour in a ten consumer economy empirical evidence suggests that welfare improving price directions can be found the whole set of these directions is then constructed

sensitivity of optimal commodity taxes to relaxing leisure goods separability and to the wage rate abstract this paper uses a new labour augmented demand functional form to calculate optimal commodity taxes for india the optimal taxes which are far from uniform are extremely sensitive to deviation from leisure goods separability and to variation in the wage rate parameter

tax reform results with different demand systems abstract we calculate the marginal welfare costs for a twelve commodity classification of the belgian indirect tax system price elasticities are estimated with rotterdam aids cbs and the linear expenditure system the ranking of the marginal welfare costs is similar when we use unrestricted estimates of the first three systems after the symmetry condition of the slutsky matrix is imposed the differences become more important however they diminish with increasing inequality aversion

on calculating the optimal commodity tax rate an alternative to social welfare maximisation abstract this paper proposes an alternative to the traditional social welfare function maximisation procedure for the calculation of optimal commodity tax rates the proposed procedure uses a loss minimisation strategy based on an explicit model of redistribution illustrative calculations on indian budget data show the potential usefulness of the procedure

does britain or the united states have the right gasoline tax this paper develops an analytical framework to assess the second best optimal level of gasoline taxation taking into account unpriced pollution congestion and accident externalities as well as interactions with the broader fiscal system we provide calculations of the optimal taxes for the us and the uk under a variety of parameter scenarios under our central parameter values the second best optimal gasoline tax is 1 01 gal for the us and 1 34 gal for the uk current tax rates are much lower than this in the us and higher in the uk the calculations are moderately sensitive to alternative parameter assumptions the congestion externality is the largest component in both nations revenue raising needs also play a significant role as do accident externalities and local air pollution potential welfare gains from reducing the current uk tax rate are estimated at nearly one fourth the production cost of all gasoline used in the uk even larger gains could be achieved by switching to a tax on vehicle miles with equal revenue yield for the us the welfare gains from optimizing the gasoline tax are smaller but those from switching to an optimal tax on vehicle miles are very large

labour supply commodity demand and marginal tax reform this paper examines the implications of extending the ahmad stern model of indirect tax reform to include labour supply the inclusion of labour supply alters the basic measure of marginal revenue cost mrc of indirect taxation and introduces the possibility of calculating a mrc for direct taxation the paper derives the expressions for these revised mrcs and provides estimates from irish data it then examines the sensitivity of the results to assumptions regarding functional form and in particular goods leisure sc parability in setting optimal tax rates policy makers face considerable difficulties explicit assumptions must be made regarding the underlying preferences of the consumer i e the functional form for the utility and demand functions and also about how expenditures are distributed sensitivity to underlying preferences is discussed by deaton i 98 i and is empirically examined by ray i986 and ebrahimi and heady i988 policy makers also face the problem that even when they do provide explicit forms for demand functions they face difficulties regarding the reliability of estimates and are also evaluating demand responses at a point possibly quite far away from the optimum the difficulties outlined above led to the development of the marginal tax reform literature with the seminal paper in this area by ahmad and stern i984 this approach has the considerable advantage of not requiring the choice of explicit utility functions nor of distributions of expenditure but instead merely requiring information on the actual position of the economy at a single point in time using actual consumption and distributions of expenditure it must be noted that tax reform does require information on demand responses so that results in this area can still be sensitive to the specification of consumer preferences and demand systems however tax reform results appear to be less sensitive than do tax design results to this

do we care a study of canada s indirect tax system this paper builds on the optimal taxation literature of diamond and mirrlees 1971 ahmad and stern 1984 and christiansen and jansen 1978 using ethically defensible measures of social welfare the effective redistribution due to the canadian indirect tax system is measured and directions of welfare enhancing tax reform are uncovered using micro data from the family expenditure survey this study finds that surprisingly the existing canadian indirect tax system is neither progressive nor regressive rather the implicit government preferences as reflected in the indirect tax system show no aversion to cross class income inequality

fixed costs and the product market treatment of preference minorities we clarify the sense in which the market outcome may be biased against preference minorities and estimate the degree of bias using an empirical model of entry into american radio broadcasting markets listening model estimates are used to infer fixed costs and these estimates are then used to compute optimal station configurations as well as the welfare weights on different groups that rationalize the observed configuration welfare weights are 2 to 3 times higher for whites than for blacks and 1 5 to 2 times higher for non hispanic than for hispanic listeners we explore the role of importing and exporting patterns in generating these findings

consumption dynamics during recessions when will durable expenditures respond strongly to economic stimulus we build from micro evidence and show that in a heterogeneous agent business cycle model with xed costs of durable adjustment responsiveness is substantially dampened during recessions our model estimates imply that during the great recession durable expenditures were half as responsive to additional stimulus as during the boom in the 1990s this procyclical responsiveness is driven by changes in the distribution of households desired durable holdings over the cycle we directly test our model by estimating this distribution empirically using psid micro data and nd that the distribution in the data moves cyclically as predicted in addition to this micro evidence we also provide support for our model s procyclical responsiveness using aggregate time series data and we show this time series evidence is inconsistent with simpler models featuring smooth adjustment costs

what calls to arms international evidence on interest rates and the choice of adjustable rate mortgages the form of the interest rate on newly issued mortgages namely whether they are adjustable rate mortgages arms or fixed rate mortgages frms varies considerably both across countries and over time we attempt to uncover the sources of this variation in the arm share of arms issued relative to total mortgage issuance our emphasis is on drawing inferences about how household mortgage choice is affected by households reactions to movements in interest rates we complement newly assembled panel data from nine countries on the arm share and mortgage interest rates with a panel instrumental variables approach in which we test exclusion restrictions that are implied by alternative explanations for variation in the arm share we uncover strong evidence in favour of current cost minimization as the proximate driver of household mortgage choice

optimal mortgage refinancing a closed form solution we derive the first closed form optimal refinancing rule refinance when the current mortgage interest rate falls below the original rate by at least in this formula w is the principal branch of the lambert w function where is the real discount rate is the expected real rate of exogenous mortgage repayment is the standard deviation of the mortgage rate is the ratio of the tax adjusted refinancing cost and the remaining mortgage value and is the marginal tax rate this expression is derived by solving a tractable class of refinancing problems our quantitative results closely match those reported by researchers using numerical methods

the theory of reform and indian indirect taxes abstract given a set of value judgements an initial state and a model of the economy one can ask whether some feasible tax change would increase welfare we do this by defining the marginal cost in terms of welfare of raising an extra rupee from the i th good the inverse optimum problem is the calculation of non negative welfare weights on households which imply that the initial state is optimum if no such welfare weights exist then a pareto improvement is possible we illustrate the concepts and results using data from the indian economy for 1979 1980 directions of tax reform for a number of specific social welfare functions and for pareto improvements are presented

tax reform from the gradient projection viewpoint abstract this paper examines the problems of gradual tax reform desirable small moves of the tax system are determined using the principles of the well known gradient projection algorithm three classical models of public finance are considered for each of them a continuous time dynamic process is exhibited along which the social welfare function increases until convergence to local second best extrema although the selection of trajectories according to the gradient projection method has some arbitrariness it leads to intuitively and economically appealing rules such as a tax reform analog of the classical optimal taxation result on production efficiency

the economics of financing higher education different arguments exist pro and contra tax financed subsidies in higher education it has been argued that private incentives to study are sufficiently high while the financing of those subsidies can be deemed regressive as they are co financed by relatively poorer non students alternatively several arguments have been put forward why higher tax financed subsidies are desirable such as externalities and credit constraints this study scrutinizes these different arguments and discusses the implications for the different ways in which higher education can be financed calculations of private returns across the oecd confirm that private incentives to invest in higher education are high however economic theory poses that it is the marginal social return that must guide policy which will reflect both equity and efficiency considerations we assess the potential regressivity of higher education subsidies using different perspectives and assess the different efficiency arguments for government intervention in higher education tax financed subsidies turn out to be regressive in most cases but depending on the perspective and the country under examination discussion of the efficiency arguments is focused on those that are most relevant in light of the empirical evidence and their relevance for the different financing modes externalities uninsurable risk credit constraints and misprediction we conclude that to deal with the more credible failures in higher education tax financed subsidies are blunt instruments for a large share of the countries under consideration shifting towards income contingent loans or graduate taxes appears more appropriate when taking into account both efficiency and equity considerations

dalton improving tax reform when households differ in ability and needs abstract in a previous paper we suggested a method for identifying tax reforms that adhere to dalton s principle of transfers approving a small enough transfer from rich to poor however even the weak requirement from that method namely prescribing a uni dimensional ordinal ranking of households by how deserving they are of a marginal income transfer is con fining here we extend the approach by formulating a two dimensional criterion for a dalton improving tax reform when there is social approval for transfers when other things are equal from the more able to the less able and from less needy households to more needy ones the possibility of applying this extended criterion in practice and a comparison with other criteria is carried out using the example of u k excise taxes

sensitivity of optimal commodity tax rates to alternative demand functional forms an econometric case study of india this study investigates on a nine commodity disaggregation of indian budget data nss 28th round the sensitivity of optimal commodity tax rates to alternative demand systems les and rnlps optimality is used here in the very special sense of being conditional on observed expenditure and fixed consumer prices the alternative sets of tax rates agree at low levels of inequality aversion but disagree widely at rawlsian levels les is heavily rejected in favour of its one parameter generalisation rnlps the results suggest that les price elasticities should not be used in optimal tax calculations the optimal tax rates imply only a modest redistribution

financial market imperfections and home ownership a comparative study abstract we explore the determinants of the distribution of owner occupancy rates across age groups using a collection of microeconomic data on 14 oecd countries in most the survey is repeated over time this allows us to construct an international dataset merging data on 39 national household surveys with aggregate data on down payment ratios we find strong evidence that the availability of mortgage finance as measured by down payment ratios affects the distribution of owner occupancy rates across age groups especially at the young end the results are consistent with previous theoretical models and have important implications for the debate on the relation between saving and growth

optimal taxes and the structure of preferences if optimal tax theory is to be the basis for calculating tax rates a close understanding is required of the relationship between the structure of preferences and the configuration of optimal tax rates otherwise hypotheses chosen by the econometrician for practical convenience may completely determine the results independently of measurement this paper explores the relationship between various types of separability particularly weak and implicit separability and optimal tax rates in the various models discussed in the literature the use of distance functions and the antonelli matrix provides a significant unification of previously disparate results in the final analysis optimal tax theory should be the basis for actual calculation of tax rates although recently there have been great advances in theoretical results and in our understanding of their meaning we are still some way from a working knowledge of whether uniform commodity taxes are in practice optimal or if not which commodities should be discriminated against present theoretical formulae do not yield clear cut results except in special cases and it has recently become clear that optimal rates depend crucially on the detailed structure of consumer preferences for example atkinson and stiglitz 3 show that with an optimal nonlinear income tax discriminatory commodity taxes are only necessary to the extent that individual commodities are not weakly separable from leisure more recently deaton 6 has shown that a similar result holds for what is perhaps the most interesting of the standard models that where there are many consumers and only a linear income tax and proportional commodity taxes are allowed in this case separability between goods and leisure together with linear engel curves for goods removes the need for differential commodity taxation in consequence nothing can be learned about commodity taxes from consumer demand studies in which commodity demands are explained conditionally on total expenditure and commodity prices and which assume linear engel curves all such studies require separability from leisure as a maintained hypothesis and so are consistent with uniform commodity taxation these results suggest that the prospects for meaningful empirical calculations of tax rates are bleak econometricians estimating commodity demand and labor supply equations make generous use of separability assumptions to enable estimation at all in consequence it is likely that empirically calculated tax rates based on econometric estimates of parameters will be determined in structure not by the measurements actually made but by arbitrary untested and even unconscious hypotheses chosen by the econometrician for practical convenience to remedy this situation and as a prelude to fruitful empirical work it is necessary to have a more explicit understanding of how preference structure affects optimal tax rates such is the object of this paper three different

the effects of rising food prices on poverty in mexico we evaluate the impact of the rise in food prices during 2006 2008 on the poverty and extreme poverty rates in mexico we concentrate on the poor s consumption of staple foods and analyze the change in their consumption brought about by changed prices we also allow households receiving income from the farming and livestock sector to benefit from increases in prices of food products we find a modest increase in poverty using 2006 2007 prices however there is a daunting effect on the poor once the 2008 prices are taken into account after considering the positive effects of public policies announced in 2008 such as reduced taxes and tariffs on food products and greater subsidies to the extremely poor the poverty rate measured through consumption increases from 25 to 33 5 and the extreme poverty rate from 10 58 to 16 given the increase in food prices further analysis using the theory of optimal taxes suggests policies oriented towards relieving the food price pressure on the mexican poor should aim at lowering the prices of eggs vegetable oil milk and chicken

a computational procedure for calculating optimal commodity taxes with illustrative evidence from indian budget data a simple procedure for calculating optimal commodity taxes is proposed which takes into account the simultaneous interdependence of taxes expenditure and price levels responses the method also allows for the social marginal utility of income to depend on prices besides expenditures in a manner implied by the assumed preference functional form illustrative calculations on indian budget data provide evidence not only in favor of the procedure but of considerable sensitivity of directions of marginal tax reforms to the data set rural or urban used and of optimal tax estimates to demand functional form copyright 1989 by the editors of the scandinavian journal of economics

analysis of the distributional impact of out of pocket health payments evidence from a public health insurance program for the poor in mexico many governments have health programs focused on improving health among the poor and these have an impact on out of pocket health payments made by individuals therefore one of the objectives of these programs is to reach the poorest and reduce their out of pocket expenditure in this paper we propose the distributional poverty impact approach to measure the poverty impact of out of pocket health payments of different health financing policies this approach is comparable to the impoverishment methodology proposed by wagstaff and van doorslaer 2003 that compares poverty indices before and after out of pocket health payments in order to escape the specification of a particular poverty index we use the marginal dominance approach that uses non intersecting curves and can rank poverty reducing health financing policies we present an empirical application of the out of pocket health payments for an innovative social financing policy implemented in mexico named seguro popular the paper finds evidence that seguro popular program has a better distributional poverty impact when families face illness when compared to other poverty reducing policies the empirical dominance approach uses data from mexico in 2006 and considers international poverty standards of 2 per person per day

monetary policy when households have debt new evidence on the transmission mechanism in response to an unanticipated change in interest rates households with mortgage debt adjust their expenditure signicantly especially on durable goods renters react to a lesser extent and outright home owners do not react at all all housing tenure groups experience a signicant change in disposable income over and above the direct impact on mortgage repayments the response of house prices is sizable driving a signicant adjustment in loanto income ratios but little change in loan to value ratios a simple collateral constraint model augmented with durable goods and a renting decision generates predictions consistent with these novel empirical ndings and suggests that heterogeneity in housing debt positions plays an important role in the transmission of monetary policy

prices and unit values in poverty measurement and tax reform analysis researchers often use unit values household expenditures on a commodity divided by the quantity purchased as proxies for market prices when calculating poverty lines and estimating consumer demand equations such proxies are often needed because community price surveys in developing economies are either absent or suffer quality problems however using unit values may result in biases due to measurement error and quality effects in a household survey experiment information on prices was obtained in three ways from unit values from a market price survey and from the opinions of householders who were shown pictures of items and asked to report the local price the three sets of price data are used to calculate poverty lines estimate price elasticities and analyze marginal tax reforms there are substantial biases when unit values are used as a proxy for market price even when sophisticated correction methods are applied performance was better for the price opinions of household members the results highlight the importance of price collection methods and the need to consider the wider costs of having potentially unreliable community level price data

the welfare effects of alcohol taxation abstract this paper analyzes the question of how to appropriately tax alcoholic beverages at a disaggregated level using the theory of tax reform the social cost of raising revenue from different alcoholic beverages is calculated the externality associated with alcohol consumption is explicitly modeled the problem is approached by building a multistage budgeting model of expenditure which is necessitated by the lack of elasticity information at the required level of disaggregation the model is applied to a 1989 data set for ontario canada evidence for the existence of welfare improving tax changes is found

tax reform and temporary inefficiency abstract if any type of direct income redistribution is permitted a very weak condition ensures that it will not be desirable or necessary to permit production inefficiency in the process of a pareto improving tax reform inefficiency arises in models which make an implausible set of assumptions about the range of policies available to the government

first degree price discrimination goes to school personalized pricing is widely discussed but seldom observed making studies of its efficacy rare yet first degree price discrimination is common in the pricing of higher education and i use data on prices and the characteristics of students admitted to a professional graduate program at a public university to estimate a matriculation demand function i then derive linear pricing functions that maximize revenue for a target number of students by allowing these functions to depend on progressively richer sets of observables i explore the effect of personalization of pricing on profit tailoring prices to a one dimensional measure of student quality would raise revenue by 2 2 per cent above the revenue with uniform pricing pricing based on both student quality and state residency raises revenue by 8 4 per cent and further tailoring based on available observables raises prices 9 0 per cent above the maximum revenue under uniform pricing pricing that obeys current statutory tuition limits raises revenue less but still by just over half as much i also infer the welfare weights that the pricing process implicitly attaches to student characteristics

poverty dominant program reforms the role of targeting and allocation rules we propose simple graphical methods to identify poverty reducing marginal reforms of transfer programs the methods are based on program dominance curves that display cumulative program benefits weighted by powers of poverty gaps these curves can be decomposed simply as sums of targeting dominance curves and allocation dominance ones and can serve to verify whether the assessment of marginal program reforms is sensitive to the choice of poverty lines and poverty measures as well as to differences across programs in revenue sources and incentive effects

tobacco consumption and taxation in italy an application of the quaids model estimates are presented of the demand for tobacco in italy in the context of a demand system approach the grouping of goods is based on varian s non parametric test for weak separability the parametric demand model is banks blundell and lewbel s quaids model which combines the empirical flexibility of quadratic logarithmic engel curves with integrability estimation is by iterative gmm procedure the estimates are used in an analysis of welfare improving tax reforms which incorporates distributional data the results are discussed with respect to the special features of the italian tobacco market

implicit policy preferences and the assessment of negotiable trade policy reforms abstract formal multilateral trade negotiations increase the pressure brought to bear on protectionist economies by foreign interests this paper explores the hypothesis that successful negotiations yield mixes of policy reforms which contribute to internationalist objectives but which minimally disturb the prior domestic political market equilibrium this disturbance is measured using weighted objective functions the weights in which embody revealed policy preferences governments are assumed to reflect these preferences in a strategic trade policy formation process which uses empirically based conjectures as to the responses of other governments and private agents the approach is applied to the negotiations on agricultural trade policy and in particular to the protectionist common agricultural policy of the european community

sentencing policy implied demographic welfare weights and the theory of sentencing reform abstract different groups of people experience varying degrees of different externalities by a government s choice of expenditures to control externalities it affects different members of the population differently these choices implicitly value the welfare of members of different groups this paper adapts the framework developed by ahmad and stern journal of public economics 1984 25 259 298 to infer welfare weights underlying a system of commodity taxation to infer the welfare weights implicitly attached to different population groups by us sentencing policy welfare improving directions of sentencing reform are also calculated

the consumption and wealth effects of an unanticipated change in lifetime resources in 2000 italy replaced its traditional system of severance pay for public employees with a new system under the old regime severance pay was proportional to the final salary before retirement under the new regime it is proportional to lifetime earnings this reform entails substantial losses for future generations of public employees in the range of 20 000 30 000 depending on seniority using a difference in difference framework we estimate the impact of this unanticipated change in lifetime resources on the current consumption and wealth accumulation of employees affected by the reform in line with theoretical simulations we find that each euro reduction in severance pay reduces the average propensity to consume by 3 cents and increases the wealth income ratio by 0 32 the response is stronger for younger workers and for households where both spouses are public sector employees this paper was accepted by amit seru finance

the matrix approach to evaluating demand equations as there is a plethora of demand models which one should be used to estimate income and price elasticities the paper sheds light on this important practical problem by developing a matrix approach to simulating mas demand equations to analyse their performance under idealized circumstances artificial data on the dependent variable are generated by one model and these are then used for the estimation of another model as an illustrative application using four popular models a 4 4 matrix is generated which gives all pair wise comparisons the performance of the models is then evaluated on the basis of the quality of the income and own price elasticity estimates

are efficient linear taxes inequitable abstract i explore the household weights in the bergson samuelson social welfare functions which have a turning point at an efficient linear tax structure the inverse optima a tax structure is defined to be inequitable if every inverse optimum has weights that increase with household productivity over part of the productivity range i find that the inequity of an efficient tax structure depends on the normality of leisure on the number of households and on the natureof household demands an efficient indirect tax structure is not inequitable if the expenditure share of each taxed commodity is constant across households this has welfare implications for the choice of tax instrument to finance a project accepted under benefit cost analysis

budget shares distributional characteristics and the direction of tax reform abstract we present a distinction between budget shares and distributional characteristics in the framework of the marginal tax reform approach of ahmad and stern journal of public economics 1984 25 259 298 in a simplified case we show that distributionally motivated tax changes based on budget shares will not be welfare improving

piecemeal tax reforms and the compensated radial elasticities of tax bases abstract it is shown that tax inefficiency is measured by the compensated radial elasticity cre of a tax base defined as the percentage reduction in that base due to a compensated 1 percent radial increase in all tax rates the rule that efficiency can be raised by switching taxes from goods with higher elasticities to those with lower elasticities becomes rigorous if elasticities is replaced by cres use of the cre can simplify and integrate the main results in the optimal tax literature

optimal commodity taxation and redistribution within households using a collective model of consumption we characterize optimal commodity taxes aimed at targeting specific individuals within the household the main message is that distortionary indirect taxation can circumvent the agency problem of the household essentially taxation should discourage less the consumption of a certain group of goods those for which the slope of the engel curves is larger for the targeted person

tax reform via commodity grouping abstract in designing indirect taxation administrative costs can be saved by placing commodities in common rate groups the corlett hague reform is used to investigate how commodities should be grouped differentiated tax groupings which dominate uniformity are identified a restriction on the size of tax changes reveals conditions for local optimality important determinants are initial budget shares and how commodities differ in terms of optimal tax characteristics e g in the single person case compensated cross wage elasticities along the line of tax characteristics the locally optimal grouping is connected

tariff design and reform in a revenue constrained economy theory and an illustration from india abstract this paper develops the theory of design and reform of protective tariffs in a revenue constrained small open economy characterized by learning by doing it shows that revenue raising requires wedges between consumer prices and shadow prices while protection when typically not achievable via subsidies directly targeted towards factor market distortions requires wedges between producer prices and shadow prices illustrative calculations in a modestly disaggregated general equilibrium model of india support the view that uniformity in protective tariffs is likely to be a reasonably good policy in situations where the government intends no discrimination within the sectors already identified for special treatment

a leaky bucket in the real world estimating inequality aversion using survey data existing evidence of inequality aversion relies on data from class room experiments where subjects face hypothetical questions this paper estimates the magnitude of inequality aversion using representative survey data with questions related to the real economy situations the respondents face the results reveal that inequality aversion can be measured in a meaningful way using survey data but the magnitudes of the estimates depend dramatically on how inequality aversion is measured no matter how measured the revealed inequality aversion predicts opinions on a wide range of questions related to the welfare state such as the level of taxation tax progressivity and the structure of unemployment benefits

undominated directions of tax reform abstract this article considers the reform of a commodity tax system consumers preferences over directions of tax reform are constructed from indirect utility functions a wicksellian decision procedure is used to define a dominance relation on the set of directions of change direction x dominates direction y if and only if a everybody prefers x to y or b x is the status quo and at least one person prefers x to y a number of characterizations of undominated directions of change are provided a related unanimity rule procedure which does not single out the status quo for special treatment is also considered particular attention is paid to the issue of whether wicksellian reforms preserve production efficiency remarks on the relationship between this work previous work in optimal taxation theory and social choice theory are also provided

developing country interests in agricultural trade reform this paper examines whether developing countries as a group would be better off in the absence of agricultural protection in the industrial north and if so whether they should support reforms negotiated between the major players in the uruguay round results from the tyers anderson gls model of world food markets suggest that the net effect of industrial country agricultural protection is beneficial to developing countries though by only a small margin even if its removal were to stimulate accelerated technical change in developing countries the same is found to be true of partial reforms which are more palatable politically such as quotas to reduce oversupply in the ec of course many developing countries including those which are members of the cairns group are badly hurt by protection in the north unfortunately however they and the other members of that group stand to gain comparatively little from the reduction of oversupply in the ec through quotas

on the hatta normality condition and tax reforms abstract the role of the hatta normality condition in the tax reform literature is discussed it is shown that in a one consumer economy the hatta normality condition only pertains to the directions of welfare improving tax reforms but has no role in determining the existence of such reforms in a many consumer economy the hatta normality condition is shown to affect both the existence and directions of strict pareto improving tax reforms it is also shown that the hatta normality condition can be used to indicate optimality or suboptimality of the economy s initial choice of lump sum transfers

the employment effects of a regional capital subsidy swales j k 1981 the employment effects of a regional capital subsidy reg studies 15 263 273 in this paper neoclassical models are developed to analyse the impact of a proportionate capital subsidy on the level of employment in a perfectly competitive and monopolistic industry in these models the level of output factor inputs product price and factor prices are determined simultaneously in both models the sign on the change in employment depends solely on the elasticity of demand for the product when the models are used to analyse the introduction of a regional subsidy there is a strong presumption that the predicted change in employment will be positive
