estimates of effective marginal tax rates on factor incomes this chapter describes a method of calculating summary measures of effective factor income tax rates in the united states using readily available data the numbers resulting from application of this method in a study are reported in the chapter and some of their possible uses are discussed the estimated factor income tax rates behave over time in a manner quite consistent with the behavior of other broad measures of federal tax policy the postwar movement in the tax rate on income from labor relative to that on income from capital or more accurately the relevant components of these tax rates provides suggestive support for the miller scholes hypothesis that the federal personal income tax has been moving in the direction of a pure consumption tax the tax rates reported in the chapter are consistent with other studies that show a decrease since the 1950s in rates of taxation at the corporate level of income from corporate held capital they are also consistent with the view that rates of taxation of such income at the noncorporate level have risen but not quite sufficiently to offset the decline in the corporate tax burden

time consistent public policy in this paper we study how a benevolent government that cannot commit to future policy should trade off the costs and benefits of public expenditure we characterize and solve for markov perfect equilibria of the dynamic game between successive governments the characterization consists of an inter temporal first order condition a generalized euler equation for the government and we use it both to gain insight into the nature of the equilibrium and as a basis for computations for a calibrated economy we find that when the only tax base available to the government is capital income an inelastic source of funds at any point in time the government still refrains from taxing at confiscatory rates we also find that when the only tax base is labour income the markov equilibrium features less public expenditure and lower tax rates than the ramsey equilibrium

individual and collective socio psychological patterns of photovoltaic investment under diverging policy regimes of austria and italy abstract photovoltaic policies show the primary effect of encouraging photovoltaic investments but also secondary effects of crowding in out individuals with specific socio psychological patterns to enhance our understanding of such crowding effects we investigated two comparative study cases with contrasting state support for photovoltaic investments high financial support in the province of bolzano south tyrol italy versus lower financial support in the province of styria austria we surveyed individual and collective investors and as a control group households who had not invested in photovoltaics at the time of data collection we first compared crowding effects of diverging pv policies and afterwards individual and collective socio psychological patterns to grasp their role for photovoltaic adoption in general protecting the environment was found to be the strongest driver for photovoltaic investments generous state support in italy widened demographics crowded in economic considerations and persons with an anthropocentric relationship towards nature however italy s high incentivized photovoltaic policy crowded out the motivations for collective energy projects and could not sufficiently encourage a sustainable diffusion of photovoltaics as investments collapsed once state funding was stopped

supply side interventions and redistribution we evaluate the eect on welfare of shifting the burden of capi tal income taxes to labor taxes in a dynamic equilibrium model with heterogeneous agents and constant tax rates we calibrate and simu late the economy we nd that lowering capital taxes has two eects i it increases e ciency in terms of aggregate production and ii it redistributes wealth in favor of those agents with a low wage wealth ratio when the parameters of the model are calibrated to match the distribution of income in terms of the wage wealth ratio the redis tributive eect dominates and agents with a high wage wealth ratio would experience a large loss in utility if capital income taxes were eliminated

biofuels and sustainable energy development in brazil summary through the assessment of three decades of the alcohol program in brazil the paper shows that adequate public policies regarding biomass production can deliver direct benefits like energy security improvement foreign exchange savings and local employment generation reduced urban air pollution and avoided co2 emissions moreover the paper shows that brazilian produced ethanol has faced economies of scale technical progress and productivity gains and is no longer dependent on subsidies to be competitive the paper also examines the potential in brazil for fostering other biofuels namely biodiesel obtained from vegetable oils as well as their implications on sustainable energy development

an equilibrium model of the business cycle with household production and fiscal policy the authors estimate a dynamic general equilibrium model of the u s economy that includes an explicit household production sector and stochastic fiscal variables they use their estimates to investigate two issues first the authors analyze how well the model accounts for aggregate fluctuations they find that household production has a significant impact and reject a nested specification in which changes in the home production technology do not matter for market variables second the authors study the effects of some simple fiscal policy experiments and show that the model generates different predictions for the effects of tax changes than similar models without home production copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

winner s curse without overbidding abstract we report the results of a series of second price auction experiments where each bidder s signal is given by a normally distributed value plus a normally distributed error while bidders values differ in one treatment they are the same in another which allows for a direct test of the winner s curse irrespective of confounding factors bidders may also fall prey to a news curse when they do not sufficiently take into account that signals and errors are correlated we find that the effects of the winner s curse are mitigated by a news curse and loss or risk aversion

optimal taxation in models of endogenous growth we study the problem of optimal taxation in three infinite horizon representative agent endogenous growth models the first model is a convex model in which physical and human capital are perfectly symmetric our second model incorporates elastic labor supply through a lucas style technology analysis of these two models points out the danger of assuming that government expenditures are exogenous in our third model we include government expenditures as a productive input in capital formation showing that the limiting tax rate on capital is no longer zero in numerical simulations we find similar effects on growth and welfare in all three models

revised feed in tariff for solar photovoltaic in the united kingdom a cloudy future ahead abstract the united kingdom uk started implementing a national feed in tariff fit mechanism on the 1 april 2010 which included specific payment tariffs for solar photovoltaic pv installations however a revised fit rate has been put in place starting from 1 april 2012 applicable to any installations with an eligibility date of on or after 3 march 2012 this paper presents first an overview of solar pv installation in the uk this followed by a general concept of the fit in the uk before analyzing the financial impact of the new fit rate on the consumers similar financial analysis is conducted with selected countries in europe the financial analysis investigates the total profit the average rate of return and the payback period it is found that the new fit rate generates very low profit minimum rate of return and a longer payback period suggesting a downward trend of solar pv uptake in the future

time consistent optimal fiscal policy this article studies the properties of optimal fiscal policy in a stochastic growth model when the government cannot commit itself beyond the next period s capital income tax rate we find that the results contrast markedly with those under full commitment first capital income tax rates are very high 65 on average versus close to zero on average under full commitment second labor income taxes are rather low on average about 12 versus a value of around 31 under full commitment finally labor income taxes are quite volatile whereas under full commitment their standard deviation is essentially zero

redistributive taxation in a simple perfect foresight model abstract we investigate the redistributive potential of capital taxation in an intertemporal maximizing model of capital formation first even unanticipated redistributive capital taxation is severely limited in its effectiveness since it depresses wages second under any convergent redistributive tax policy which maximizes a paretian social objective the capital income tax will converge to zero independent of the factor supply elasticities these results are independent of workers holdings of capital

on the taxation of human and physical capital in models of endogenous growth abstract this paper studies the effects of factor income taxation and of subsidies to human capital accumulation in models of endogenous growth it examines in particular how these effects depend on the specification of the leisure activity and on the technology and tax treatment of the sector producing human capital it shows that the negative effects of factor income taxes on economic growth are stronger when the human capital sector is a market good under these circumstances a subsidy to human capital accumulation can offset the direct growth effects of labor taxation making it akin to a consumption tax the paper then briefly discusses the normative implications of the analysis for the optimal taxation of factor incomes

design of an economically efficient feed in tariff structure for renewable energy development abstract evidence suggests albeit tentatively that feed in tariffs fits are more effective than alternative support schemes in promoting renewable energy technologies rets fits provide long term financial stability for investors in rets which at the prevailing market price of electricity are not currently cost efficient enough to compete with traditional fossil fuel technologies on the other hand if not properly designed fits can be economically inefficient as is widely regarded to have been the case under the public utility regulatory policies act of 1978 purpa under purpa too high a guaranteed price led to the creation of so called purpa machines poorly performing generating units that could survive financially only because of heavy subsidies that came at the expense of retail customers similarly because of their adverse impacts on retail electricity rates german fits have been subject to increasing political pressure from utilities and customers in this paper we propose an innovative two part fit consisting of both a capacity payment and a market based energy payment which can be used to meet the renewables policy goals of regulators our two part tariff design draws on the strengths of traditional fits relies on market mechanisms is easy to implement and avoids the problems caused by distorting wholesale energy markets through above market energy payments the approach is modeled on forward capacity market designs that have been recently implemented by several regional transmission organizations in the usa to address needs for new generating capacity to ensure system reliability

envisaging feed in tariffs for solar photovoltaic electricity european lessons for canada abstract while it is widely agreed that support schemes need to be put in place to promote the use of renewable electricity there is less consensus as to what are the best kinds of strategies to use what is attracting increasing attention in canada is a system of renewable portfolio standards in this all power suppliers are under an obligation to ensure that a certain percentage of the electricity they generate is from renewable resources they can either generate that electricity themselves or purchase green certificates from those who have used renewables to generate electricity recent experience from europe however suggests that a whole hearted commitment to this single strategy could be premature and potentially damaging for the development of all kinds of renewable electricity in canada solar photovoltaics included on the other side of the atlantic ocean the use of so called feed in tariffs that is an obligation for utilities to purchase at a set price the electricity generated by any renewable energy resource is widely credited with accelerating the development of renewable electricity in many countries the purpose of this article is to reflect upon this european experience with feed in tariffs to stimulate discussions regarding what promise they might hold for the development of solar photovoltaic electricity in canada the article is divided into three main sections in the first section policies to promote renewable electricity presently in place in different parts of canada are reviewed attention is then focused more specifically in the second section of this article upon feed in tariffs after defining and describing this alternative system experiences in the countries of the european union are reviewed the main strengths and weaknesses of feed in tariffs in the european experience are also examined the focus then moves back to canada in the third section of the article in this a system of feed in tariffs is proposed for the province of ontario in order to provide just one example of the kind of support that could be forthcoming

heterogeneity in capital and skills in a neoclassical stochastic growth model does a heterogeneous agents version of a neoclassical model with labor leisure choice replicate the distributions of consumption and working hours observed in the cross sectional data does incorporating heterogeneity enhance the aggregate performance of the representative agent model we address these questions in a complete market model economy with two sources of heterogeneity initial endowments and non acquired skills we find positive answers to both questions

feed in tariffs combined with capital subsidies for promoting the adoption of residential photovoltaic systems abstract both feed in tariffs fits and capital subsidies have been widely employed to promote the adoption of renewable energy technologies this study sheds light on the combined use of fits and capital subsidies the purpose of the study is to clarify their optimal combinations in order to encourage households to adopt photovoltaic pv systems the study develops a microeconomic model embodying the idea of two part tariffs the most important findings concern the combination that maximizes social welfare if fits are applied to the total pv electricity generated they should be set at the avoided cost per unit of pv electricity and capital subsidies should be used to control the number of adopters whereas if fits are applied to only surplus pv electricity the previous principle is distorted however a numerical example suggests that the distortion has little effect on the maximized social welfare and thus it makes little difference whether fits are applied to all pv electricity or just the surplus pv electricity the findings may also be applied to the adoption of wind power generation systems and to adoption by businesses

communication commitment and growth abstract we study the effect on the growth of an economy of alternative financing opportunities in a stochastic growth model with incentive constraints efficient accumulation mechanisms are designed and computed for economies that differ in their incentive structure we show that when borrowing is subject to information constraints there is a computable efficient transfer mechanism that does not affect capital accumulation and investment patterns even though consumption patterns and the distribution of wealth are affected in contrast enforcement constraints can severely reduce the outside financing opportunities and affect investment patters and economic growth we adapt numerical algorithms for obtaining numerical solutions of these models

a residence time model of housing markets abstract this paper estimates a semi markov model of housing markets in which families move from one home to another spend a random amount of time in each home and choose whether to own or to rent at each move limiting conditions of the semi markov process are used to characterize the steady state frequency of owner occupied housing and to simulate the impact of changes in housing tax policy this approach differs markedly from previous studies of housing tax policy which focus on the entire population as opposed to the movers and ignore the effect of household residence times see king 1980 rosen 1979 white and white 1977 or laidler 1969 residence times further influence the analysis by affecting the relative cost of owning to renting in the tenure choice model homeowners pay legal and realtor fees at the time they move out of their homes which renters do not have to pay the discounted value of these fees declines with length of stay and provides a structural explanation of why families with longer residence times have a greater propensity to own results from the empirical analysis suggest that the semi markov model closely predicts conditions in the united states and provide important insights into the effects of housing tax policy residence times are also found to influence household tenure choice through their impact on the discounted legal and realtor fees paid by homeowners

on the size of u s government political economy in the neoclassical growth model we study a dynamic version of meltzer and richard s median voter model of the size of government taxes are proportional to total income and they are redistributed as equal lump sum transfers voting takes place periodically over time and each consumer votes for the tax rate that maximizes his equilibrium utility we calibrate the model to u s data key elements in the calibration are the income and wealth distribution and the parameters governing the leisure and consumption choices the total size of transfers predicted by our political economy model is quite close to the size of transfers in the data

small business set asides in procurement auctions an empirical analysis as part of public procurement many governments adopt small business programs to pro vide contract opportunities for businesses often with preferences for firms operated by mem bers of groups designated as disadvantaged the redistribution arising from such programs however can introduce significant added costs to government procurement budgets in this paper the extent to which small business set asides increase government procurement costs is examined the estimates employ data on japanese public construction projects where approximately half of the procurement budget is set aside for small and medium enterprises smes applying a positive relationship between profitability and firm size obtained by the non parametric estimation of asymmetric first price auctions with affiliated private values a counterfactual simulation is undertaken to demonstrate that approximately 40 percent of smes would exit the procurement market if set asides were to be removed surprisingly the resulting lack of competition would increase government procurement costs more than it would offset the production cost inefficiency

feed in tariff vs renewable portfolio standard an empirical test of their relative effectiveness in promoting wind capacity development abstract this paper examines the relative effectiveness of feed in tariff fit and renewable portfolio standard rps in promoting wind capacity development using panel data conservative estimates suggest that on average across countries fit increases total wind capacity more than rps by a magnitude of about 1800 mw when using time variant policy indicators the difference between the two policies increases to nearly 2000 mw roughly 8 of 2009 cumulative capacity in germany as for annual wind capacity since 2005 this paper has found no significant difference between fit and rps it is also found that wind energy development responds to high electricity demand and high oil dependence

on the efficiency and equity trade off abstract the concept of policy measures that create a potential pareto improvement has dominated normative economics the use of this concept in welfare economics relies on the availability of discriminatory lump sum transfers in such a way that the implementation of the efficient policy measure leads to a pareto movement in the economy however most studies of efficient policies preclude by assumption the existence of lump sum taxation this paper proposes in economies amenable to gorman aggregation one simple methodology to rank alternative allocations in terms of their distributional implications in a world with no lump sum transfers this methodology is simple because it is independent of the distribution of characteristics in the economy then for a specific policy measure it can be easily identified whether it implies an equity efficiency trade off the method is illustrated by analyzing the effects on inequality of the elimination of capital taxation the reduction of the inflation tax and the liberalization of capital movements in a small open economy

the impact of public information on bidding in highway procurement auctions a number of papers in the theoretical auction literature show that the release of information regarding the seller s valuation of an item can cause bidders to bid more aggressively this widely accepted result in auction theory remains largely untested in the empirical literature recent theoretical work has also shown that this effect can be more pronounced in auctions with larger common cost uncertainty we examine the impact of a policy change by the oklahoma department of transportation that led to the release of the state s internal estimate of the costs to complete highway construction projects we perform a differences in differences analysis comparing bidding in texas a state that had a uniform policy of revealing the same information all throughout the period of analysis to bidding in oklahoma our results show that in comparison to texas auctions the average bid in oklahoma fell after the change in engineers cost estimate ece policy this decline in bids was even larger for projects where the common uncertainty in costs is greater moreover the within auction standard deviation of bids fell after the change in ece policy with the most significant decline observed again in projects with greater common cost uncertainty

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

the welfare cost of factor taxation in a perfect foresight model this paper examines the marginal efficiency cost of various factor taxes in a dynamic general equilibrium model the au thor solves for the excess burden of anticipated and unanticipated t emporary and permanent tax policies using a range of estimates for taste and technology parameters he finds excess burdens larger than those indicated by previous studies that use static models these exc ess burdens are sensitive to parameter values and timing however th e rankings of alternative tax policies turn out to be insensitive to structural parameter values copyright 1987 by university of chicago press

the potentials of a reverse auction in allocating subsidies for cost effective roof top photovoltaic system deployment abstract photovoltaic pv has developed to one of the most promising technologies for renewable electricity generation the austrian government currently provides subsidies for roof top pv systems through a constant administratively determined feed in tariff or an investment co funding in both subsidy schemes applications are approved on a first come first served basis there are concerns about i the selection of suitable roofs for pv systems and ii allocating subsidies among applicants to deploy roof top pv systems cost effectively thus we analyze the potentials of a simple discriminative first price reverse auction application scheme applicants define individually the required level of subsidy and those with the lowest request for subsidies are selected in an ex post analysis we evaluate the potentials of such a scheme in increasing power output and saving public spending for the federal state of vorarlberg in austria results indicate a potential increase of cumulated produced electricity between 15 and 18 in comparison to the current policy in addition a reverse auction based system would lead to savings of public spending per kwh between 20 and 41

economic and environmental effectiveness of renewable energy policy instruments best practices from india abstract renewable energy re has been identified as a key tool to counter climate change and enhance energy security countries across the globe have been promoting this sector by several policy measures however limited research has been undertaken on the economic and environmental efficacy of re policy instruments especially in context of emerging economies like india which have witnessed substantial capacity addition and have set ambitious targets to de carbonize their economy this paper identifies 25 innovative practices followed in india which have enabled accelerated re capacity addition with minimal financial obligations these include energy entrepreneurship energy democratization private sector participation hedging and apportioning re procurement use of auctions with stringent participatory norms creditworthy counter party leverage of risk capital by developmental institutions regular revision of tariffs environmental cess on polluting industries long term re purchase trajectory and incentivizing green power output results indicate high financial impact of instruments support of us 3 5 mw h over applicable tariff which gets neutralized when tax inflow is considered lower carbon abatement cost us 3 6 tco2eq depicts high environmental efficacy the paper shares best practices from india in terms of efficient use of re policy enablers which may be contextualized in other emerging economies as per the local requirements

optimal fiscal policy in a stochastic growth model although most neoclassical growth models focus on competitive equilibria which are pareto optimal and ignore the role of government recent works by romer 28 29 judd 20 baxter and king s and bizer and judd 7 have shown that government can be introduced into and suboptimal equilibria can be studied in these models as well their studies however are positive analyses of the effects of fiscal policy in competitive equilibria the purpose of this paper is to apply ramsey s 27 theory of optimal taxation to the normative study of fiscal policy in a stocastic growth model ramsey studied a static representative consumer economy with many goods in his formulation a government consumes a fixed amount of these goods which it purchases at market prices and finances by levying flat rate excise taxes prices and quantities are determined in a competitive equilibrium the government is benevolent and its objective is to choose the optimal tax rates to maximize the representative consumer s utility a number of economists among them kydland and prescott 23 barro 3 turnovsky and brock 31 and lucas and stockey 26 have noted that ramsey s formulation can be applied to dynamic economies with uncertainty if one reinterprets the goods in static problems as dated state contingent goods in this framework a fiscal policy is a rule which specifies state contingent tax rates and the amount of public debt issue in each date the optimal fiscal policy is defined as the one which leads to a quantity
