Taxation and Heterogeneous Preferences

Non-linear income taxes and linear commodity taxes are analysed when people differ with respect to ability, high-skilled agents have heterogeneous preferences, and neither individual abilities nor preferences are observable. The paper highlights how informational constraints may motivate differential treatment of people with different preferences for leisure even if unequal treatment is not desirable per se. Which preference type will be better or worse off is shown to depend on the self-selection constraints associated with the information asymmetry. We characterize pure income tax optima, which may be bunching or separating optima. In particular, the income tax may not be able to distinguish between those low-income people who are low-skilled and those who have strong preference for leisure. As is shown, there may still be an impact on the optimum income tax schedule as it will depend on the composition of the population with respect to types of individuals. Finally, the paper addresses what can be achieved by commodity taxes when preferences are heterogeneous, in particular, in terms of targeting groups that the income tax is incapable of discriminating between.optimum taxation, heterogeneous preferences, asymmetric information.

The Role of Prices on Excludable Public Goods

When a poublic good ist excludable it is possible to charge individuals for using the good. We study the role of prices onexcludable public goods using an extension of the Stiglitz-Sternversion of the Mirrlees optimal income tax model. Our discussionincludes both the case where the public good is a final consumergood and the case where it is an intermediate good.We demonstrate that for a public consumer good charging apositive price may be desirable, but only under certain conditions.However, charging a lower than optimal price may be less efficientthan setting a zero price. Conditions are identified under which consumers should be rationed in their demand rather thanadjusting demand to price. We also conclude that producers using an intermediate public good as input should not be charged a positive price.excludable public goods, public sector pricing, information constrained Pareto efficiency

Nonparametric Estimation of Labor Supply Functions Generated by Piece Wise Linear Budget Constraints

The basic idea in this paper is that labor supply can be viewed as a function of the entire budget set, so that one way to account non-parametrically for a nonlinear budget set is to estimate a nonparametric regression where the variable in the regression is the budget set. In the special case of a linear budget constraint, this estimator would be the same as nonparametric regression on wage and nonlabor income. Nonlinear budget sets will in general be charac-terized by many variables. An important part of the estimation method is a procedure to reduce the dimensionality of the regression problem. It is of interest to see if nonparametrically estimated labor supply functions support the result of earlier studies using parametric methods. We therefore apply parametric and nonparametric labor supply functions to calculate the effect of recent Swedish tax reform. Qualitatively the nonparametric and parametric labor supply functions give the same results. Recent tax reform in Sweden hasincreased labor supply by a small but economically important amount.Nonparametric estimation; labor supply; nonlinear budget constraints; tax reform

The Standard Deviation of Life-Length, Retirement Incentives, and Optimal Pension Design

In this paper, we consider how the retirement age as well as a tax financed pension system ought to respond to a change in the standard deviation of the length of life. In a first best framework, where a benevolent government exercises perfect control over the individuals’ labor supply and retirement-decisions, the results show that a decrease in the standard deviation of life-length leads to an increase in the optimal retirement age and vice versa, if the preferences for “the number of years spent in retirement” are characterized by constant or decreasing absolute risk aversion. A similar result follows in a second best setting, where the government raises revenue via a proportional tax (or pension fee) to finance a lump-sum benefit per year spent in retirement. We consider two versions of this model, one with a mandatory retirement age decided upon by the government and the other where the retirement age is a private decision-variable.uncertain lifetime, retirement, pension system

Optimal Redistributive Taxation when Government’s and Agents’ Preferences Differ

Paternalism, merit goods and specific egalitarianism are concepts we sometimes meet in the literature. The thing in common is that the policy maker does not fully respect the consumer sovereignty principle and designs policies according to some other criterion than individuals’ preferences. Using the self-selection approach to tax problems developed by Stiglitz (1982) and Stern (1982), the paper provides a characterization of the properties of an optimal redistributive mixed tax scheme in the general case when the government evaluates individuals’ well-being using a different utility function than the one maximized by private agents.optimal taxation, behavioral economics, paternalism, merit goods, non-welfarism

Welfare Enhancing Marginal Tax Rates: The Case of Publicly Provided Day Care

There is a well established case for public provision of certain private goods when the government pursues income redistribution under asymmetric information about the skill levels of the agents of the economy. This paper higlights the role of tax funding of day care for children, which is a striking example of a valid case for public provision. We demonstrate that the optimal income tax should face alla agents with the (social) cost of the day care they need in order to earn futher income. In this sense day care should not be subsidised. It is simply paid for via the tax bill. However, such a payment scheme, rather than a day care fee, is crucial for alleviating the self-selection constraint of the asymmetric information, non-linear income tax model, as it imposes a burden of paying for superfluous day care on a mimicking high-skilled agent. Also, deviating from conventional preference assumptions, we show that heterogeneity of preferences for work and day care does not invalidate the Pareto improving properties of this kind of public provision.Day care; Marginal income tax; Public provision; Private goods; In-kind transfer; Heterogeneous preferences

The Political Economy of Publicly Provided Private Goods

A large share of public funds is spent on private goods (education, health care, day care, etc.). This paper integrates two different approaches to the analysis of public provision of private goods. While normative public economics has established an efficiency case for such provision, the commonly held political economy view has been that it is an economically inefficient phenomenon generated by the political process. The present paper argues that the central mechanism studied in the normative approach is equally relevant to voting models of decisions on public provision. It is shown that under plausible information constraints economically efficient public provision of private goods will be part of politically rational decisions emerging from a median voter process or a representative democracy of political parties.political economy; public provision; private goods; in-kind transfers

The Role of Prices on Excludable Public Goods

When a public good is excludable it is possible to charge individuals for using the good. We study the role of prices on excludable public goods within an extension of the Stern-Stiglitz version of the Mirrlees optimal income tax model. Our discussion includes both the case where the public good is a final consumer good and the case where it is an intermediate good. We demonstrate that for a public consumer good charging a positive price may be desirable, but only under certain conditions.

Conditions are identified under which consumers should be rationed in their demand rather than adjusting demand to price.

Hourly Wage Rate and Taxable Labor Income Responsiveness to Changes in Marginal Tax Rates

Recently, a voluminous literature estimating the taxable income elasticity has emerged as an important field in empirical public economics. However, to a large extent it is still unknown how the hourly wage rate, an important component of taxable income, reacts to changes in marginal tax rates. In this study we use a rich panel data set and a sequence of tax reforms that took place in Sweden during the 1980’s to estimate the elasticity of the hourly wage rate with respect to the net-of-tax rate. While carefully accounting for the endogeneity of marginal tax rates as well as other factors that determine wage rates we do find a statistically significant response both among married men and married women. The hourly wage rate elasticity with respect to the net-of-tax rate is estimated to 0.14-0.16 for males and 0.41-0.57 for females. In addition, we obtain uncompensated taxable labor income elasticities of around 0.21 for men and 0.96-1.44 for women. In contrast to earlier studies, we also find significant income effects for males. Accordingly, for males the compensated taxable labor income elasticity is about 4 percentage points higher than the uncompensated one.income taxation, hourly wage rates, work effort, taxable income
