Distributional national accounts for the Netherlands and a comparison with 12 other countries

Most inequality studies rely on micro data that do not capture a substantial share of income identified in the national accounts. In the Netherlands, almost one fifth of household disposable income is missed by current inequality statistics. In this paper, we present inequality statistics for the Netherlands that capture all of household income, so-called distributional national accounts. Compared to the current inequality statistics, the Gini coefficient for disposable income increases substantially from 0.289 to 0.337. Cross-country comparisons show that such a change between Gini coefficients based on micro-data versus Gini coefficients based on distributional national accounts does not apply to all countries. The difference between both Gini coefficients varies not only between countries in the size, but also in the sign of the difference.     

Give and Take Between Households and the State: Development and Application of A Benefaction–Contribution Ratio

This study defines a “Benefaction–Contribution Ratio” (BCR), describing the extent to which households are net beneficiaries of or contributors to the economy in relation to income and consumption. Such issues are central to assessment and targeting of policies such as social welfare and taxation. We apply the ratio to 21,144 South African households. South Africa employs various taxation‐funded social grants and subsidized services. A central question is how such transfers affect real household income and consumption. We find that the constitution of social transfers as a function of tax adjusted earned income significantly augments household buying power. Furthermore, we hypothesize and find a negative curvilinear shape which has implications for design of taxation and welfare. This constitution and distribution of this ratio may be useful for international benchmarking and household planning, and as an economic predictor of outcomes such as job seeking, entrepreneurial behavior, family planning, migration, and tax evasion.     

Green tax reforms and habits

Using a dynamic general equilibrium model, we explore the role of habit formation when analyzing green tax reforms under the double dividend hypothesis. We assume increases in energy taxes and adjust capital taxation in a revenue-neutral framework to evaluate the effects on welfare. Since the existence of an environmental dividend is uncontroversial, we mainly focus on the efficiency dividend. Our findings show that, when taxes on household energy consumption increase, habits and transitional dynamics alter household decisions, and change the efficiency dividend. However, when the tax increase is on energy used as an input, reform always induces a welfare cost in terms of efficiency. In this case, habits play a less important role.     

On the marginal excess burden of taxation in an overlapping generations model

We extend marginal excess burden (MEB) analysis in public finance literature to a dynamic general equilibrium model with incomplete markets and heterogeneous households. This extension allows us to quantitatively assess efficiency ranking and incidence of taxes. Our results indicate a disparity in welfare cost and distributional consequence of different forms of taxation on capital, labor and consumption. According to our MEB ranking, capital income taxation appears to be least efficient as it results in larger marginal excess burdens, compared to labor income tax and consumption tax. The tax incidence analysis shows variation of tax burdens across households, depending on their age, income type and generation. In particular, older households with higher income bear the highest burden of company income tax; meanwhile, future born households bear the highest burden of personal income tax. Hence, our MEB analysis demonstrates a fruitful approach to better understanding efficiency and incidence of tax reforms in one unified framework.     

Taxation of a Polluting Non-renewable Resource in the Heterogeneous World

This paper extends the literature on the taxation of polluting exhaustible resources by taking international heterogeneities and national tax-setting into account. We propose a two-country Romer model of endogenous growth in which the South is endowed with the stock of an essential polluting non-renewable resource and world economic growth is driven by a northern research sector. We consider the stock of pollution as affecting global welfare. First, we characterize the optimal environmental taxation policies. Second, we examine the impacts of national taxes. Their time profile determines the extraction path, the dynamics of pollution accumulation and that of world output. Their respective levels entail inter-country interactions by altering the efficiency of the world resource allocation, the tax revenues and the resource rents. We study isolatedly the distortional and distributional effects of local taxes. Then, we completely assess the overall impact of a unilateral tax increase. Finally, we find that, even if heterogeneous countries coordinate their taxation policies to correct the global environmental problem, their divergent strategic interests cause another global, non-environmental distortion in the allocation of the resource.     

A tale of two Ginis in the US, 1921–2012

Following a methodology by Jantzen and Volpert (2012), we use IRS Adjusted Gross Income data for the US (1921–2012) to estimate two Gini indices representing inequality at the bottom and the top of the income distribution, and to calculate the overall Gini as a function of the parameters underlying the two indices. A steady increase in the overall Gini since the Second World War actually hides two different periods of distributional changes. First, the increase in inequality from the mid 1940s to the late 1970s is driven by rising inequality at the bottom of the income distribution that more than offsets a decrease in inequality at the top. The implication is that middle-income earners gained relative to high-incomes, and especially relative to low-income earners. Second, the rise in the Gini after 1981 is driven by rising inequality at the top. Third, top-driven inequality follows a U-shaped trajectory consistent with Piketty and Saez (2003, 2006). Fourth, the welfare effects of the different distributional changes behind increasing inequality can be evaluated in light of the Lorenz-dominance criterion by Atkinson (1970): we argue that the rise in inequality since 1981 is much more likely to be associated with a social welfare loss net of compensating growth.     

Measuring fossil resource inequality—A case study for the UK between 1968 and 2000

This paper quantifies fossil resource inequalities amongst income quintiles in the UK between 1968 and 2000. It calculates a resource-based Gini coefficient using an input-output based resource allocation model.The results show that the Gini coefficient for total fossil resource consumption grew by 24% over the time period. By comparison the Gini coefficient for overall household expenditure rose by only 13%. The increase in resource inequality was prompted by the rising demand by high income quintiles for goods and services such as: “fuel and light” (heating and lighting the home), “car use” (private transportation), “recreation”, “travel” and “other services”. The analysis shows further that the Gini coefficient for “direct” fossil resources (“fuel and light” and “car use”) was lower and rose less steeply than the Gini coefficient for fossil resources embodied in other goods and services (indirect fossil resource requirements).Investigation into the drivers behind direct and indirect resource inequalities suggests a number of policy conclusions. Firstly, it is clear that policy initiatives to reduce fossil resource requirements (and the associated climate change impacts) must pay careful attention to distributional differences. Additionally, increased attention needs to be paid to the inequalities associated with indirect fossil resources consumption as well as the more visible direct resource inequalities.     

Environmental taxes with heterogeneous consumers: an application to energy consumption in France

This paper constructs a model with four groups of households who have preferences over labor supply, consumption of polluting (energy related) and non-polluting (non-energy) goods, and emissions. It quantifies the model for the French economy and computes its optimal tax equilibria under nine second-best tax regimes. We find that the redistributive role of environmental taxes requires the polluting goods to be taxed at a rate much below their marginal social damage. These goods may even require an outright subsidy if the society values equality ‘a lot’. Secondly, if environmental taxes that have an exclusively externality-correcting role, they benefit all types—although the gains are rather modest. The gains and losses become more substantial when environmental taxes have a redistributive role as well. Third, setting the environmental tax at its Pigouvian level, rather than its optimal externality-correcting-cum-redistributive level, benefits the high-income group at the expense of the low-income groups. Fourth, nonlinear taxation of polluting goods, and nonlinear commodity taxation in general, is a powerful redistributive mechanism. Fifth, introducing environmental taxes in the current French tax system, with its suboptimal income taxes, results in substantial welfare gains for the highest income group and a sizable loss for the least well-off persons.     

Union Wage Setting and Capital Income Taxation in Dynamic General Equilibrium

This paper concerns the effects of capital income taxation in a dynamic general equilibrium framework with union wage setting, when households face taxes related to both labor and capital. One purpose is to characterize the general equilibrium solution. Another is to study the effects of increased capital income taxation – in terms of the responses in real wages, employment, capital stock, output and consumption – and relate these behavioral responses to the overall tax structure. We also derive a cost–benefit rule for the purpose of analyzing the welfare effects of a small shift from labor income taxation to capital income taxation.     

The Household, Time Use and Tax Policy

This paper is concerned with modelling household decisions andthe welfare effects of tax policy. It seeks to emphasise theimportance of a model that incorporates household productionand can take account of the evident female labour supply heterogeneityacross two-parent families. If, after having children, someproportion of households substitute domestic for market laboursupply, the income and consumption variables used as the taxbase in most countries may be poorly correlated with livingstandards. Taxes and welfare programs based on these variablesmay increase inequality by shifting the overall tax burden tolow and middle wage families with both partners in work, awayfrom families with much higher wages and in which only one memberworks to earn the same joint market income. The paper combinesdata on time use, income, taxes and benefits to show how theytrack female labour supply over the life cycle, resulting inmuch higher tax burdens on two-earner households.

Indirect Taxation and Gender Equity: Evidence from South Africa

Abstract

This study adds to the growing literature on the distributional effects of indirect or consumption taxes in developing countries by exploring whether these taxes have differential gender outcomes. Using data from Statistics South Africa's 2000 Income and Expenditure Survey, the study investigates differences in tax incidence between “female-type” and “male-type” households, classified according to their demographic and economic attributes. The results suggest that zero-rating a well-targeted selection of basic foodstuffs and fuel for household use is important in protecting female-type households, especially those in the lowest quintiles and with children, from bearing an otherwise disproportionate share of the tax burden. In contrast, high taxes on alcohol, tobacco, and fuel for private transport result in a larger incidence on male-type households. The study also suggests ways in which the indirect tax structure could be refined to further reduce the large gender (and income) inequities that exist in South Africa.     

Inequality within generation: Evidence from France

Intra-generational inequalities focus on the distributions within age groups. On the basis of French household income surveys carried out from 1996 to 2014, the Gini coefficient and D9/D1 inter-decile ratio were calculated so as to evaluate intra-generational income inequality before and after redistribution by the tax and welfare system. Age-Cohort-Period models were then estimated in order to disentangle age and generation effects. Over a life cycle, intra-generational inequality displays a hump-shaped curve peaking at age 55–59. This inequality is significantly lower among the youngest, whichever inequality indicator is used, and among the oldest, when measured by the inter-decile ratio. Comparison of pre- and post-redistribution income reveals that the tax and welfare system particularly reduces inequality among the young. Intra-generational inequality measured by the Gini coefficient increases significantly from one generation to the next. Measured by the inter-decile ratio, the increase is considerable for the gross income of those generations born from the 1970s on. However, the tax and welfare system has compensated for this increase, because analysis of the inter-decile ratio applied to disposable income shows no significant difference between generations.     

Indirect taxation and the welfare effects of altruism on the optimal fiscal policy

This paper analyzes the welfare effects of altruism on the optimal fiscal policy. The existence of positive bequests links present and future generations in the economy. We show that these altruistic links provide a new role for indirect taxation (consumption and estate taxes) with important welfare implications. We use three different altruistic approaches (warm-glow, dynastic, and family) to illustrate how the presence of bequests in the budget constraint of the donee gives the government the ability to use indirect taxation to mimic lump-sum taxes and to implement the first-best outcome in the long-run. This channel is not present in economies without altruism, such as the infinite-lived consumer economy or the overlapping generations economy, where long-run welfare is suboptimal and indirect taxation is irrelevant.     

Fiscal Incidence in Ghana

We use methods developed by the Commitment to Equity Institute to assess the effects of government taxation, social spending and indirect subsidies on poverty and inequality in Ghana. We also simulate several policy reforms to assess their distributional consequences. Results show that, although the country has some very progressive taxes and well‐targeted expenditures, the extent of fiscal redistribution is small, but about what one would expect given Ghana's income level and relatively low initial inequality. Results for poverty reduction are less encouraging: were it not for the in‐kind benefits from health and education spending, the overall effect of government spending and taxation would actually increase poverty in Ghana. Eliminating energy subsidies and at the same time reallocating part of the savings to well‐targeted transfer programs could lower the fiscal deficit while reducing inequality and protecting the poor.     

Corporate taxes, growth and welfare in a Schumpeterian economy

I take a new look at the long-run implications of taxation through the lens of modern Schumpeterian growth theory. I focus on the latest vintage of models that sterilize the scale effect through a process of product proliferation that fragments the aggregate market into submarkets whose size does not increase with the size of the workforce. I show that the following interventions raise welfare: (a) granting full expensibility of R&D to incorporated firms; (b) eliminating the corporate income tax and/or the capital gains tax; (c) reducing taxes on labor and/or consumption. What makes these results remarkable is that in all three cases the endogenous increase in the tax on dividends necessary to balance the budget has a positive effect on growth. A general implication of my analysis is that corporate taxation plays a special role in Schumpeterian economies and provides novel insights on how to design welfare-enhancing tax reforms.     

THE DISTRIBUTIONAL CONSEQUENCES OF GOVERNMENT SPENDING AND TAXATION IN THE U.S., 1989 AND 2000

We assess the effects of government expenditures and taxation on household economic well-being in the United States in 1989 and 2000. Net government expenditure is estimated as the difference between government expenditures incurred on behalf of the household sector—transfers and public consumption—and the taxes paid by that sector. We incorporate the estimates of net government expenditures into a wealth-adjusted measure of income. We find that overall inequality in our income measure is considerably reduced by net government expenditures. Results from decomposition analysis show that the inequality-reducing effect of net government expenditures owed more to expenditures than to taxes.     

Foreign Aid,Government Spending,and the Environment

Using an endogenous growth model, this paper examines the growth and welfare effects of the allocation of foreign aid in the recipient economy. As public inputs are a productive factor, a rise in the allocation of aid to the public inputs increases growth and hence the welfare of the economy. However, raising the ratio of aid to pollution abatement may not help an economy, because it crowds out public inputs. Since public inputs are also partly financed by income taxation, the welfare‐maximizing income tax rate is larger than the growth‐maximizing rate, because a portion of the aid constitutes a lump‐sum transfer and can increase household consumption and hence welfare.     

Tax competition with parasitic tax havens

We develop a tax competition framework in which some jurisdictions, called tax havens, are parasitic on the revenues of other countries, and these countries use resources in an attempt to limit the transfer of tax revenue from capital taxation to the havens. We demonstrate that the full or partial elimination of tax havens would improve welfare in non-haven countries. We also demonstrate that the smaller countries choose to become tax havens, and we show that the abolition of a sufficiently small number of the relatively large havens leaves all countries better off, including the remaining havens. We argue that these results extend to the case where there are also taxes on wage income that involve administrative and compliance costs.     

关于完善我国环保型税收政策的探讨

环保型税收在环境保护方面具有不可替代的作用。随着我国经济发展环境问题日益凸现,运用税收手段解决环境问题已成为各国通行的做法。鉴于我国目前以流转税为主,经济发展水平不高,所以不能完全照搬西方的做法,但西方发达国家生态税有许多值得我们借鉴的成功经验。我国税制中与生态环境有关的政策,散见于资源税、消费税、企业所得税等几个税种中,有些仍以费的形式存在,有较大的空间。建议应增加现行税种的环境保护内涵,实行专门的环保税种,实行费改税等。     

The Collective Household, Household Production and Efficiency of Marginal Reforms

Most research on the welfare properties of taxes employs the unitary model of the household, ignoring household production. A simple model provides expressions for the changes in individual utility given marginal reforms to government policy. It is shown that the burden of a higher tax on household goods falls on the household member that consumes more than they produce or purchase. Numerical calculations show that price substitution (complementarity) between home and market labor increases (decreases) aggregate efficiency costs of a marginal redistribution of income without impacting the intra-household distribution of utility changes. Modeling household goods as public versus private can alter the distributional consequences of marginal reforms.
