Are benevolent dictators altruistic in groups? A within-subject design

We use a within-subject experimental design to investigate whether systematic relationships exist across distinct features of individual preferences: altruism in a two-person context, risk aversion in monetary outcomes, and social preferences in a group context. We find that altruism is related to demographic variables, including years of education, gender, and age. Perhaps most importantly, self allocation in a two-person dictator game is related to social preferences in a group context. Participants who are more generous in a dictator game are more likely to vote against their self-interest in a group tax redistribution game which we interpret to be an expression of social preferences.     

Taxation,redistribution, and observability in social dilemmas

In the presence of social dilemmas, cooperation is more difficult to achieve when populations are heterogeneous because of conflicting interests within groups. We examine cooperation in the context of a nonlinear common pool resource game, in which individuals have unequal extraction capacities and have to decide on their extraction of resources from the common pool. We introduce monetary and nonmonetary mechanisms in this environment. The two monetary mechanisms are tax extraction and redistribution of the tax revenue. These include a Pigovian per‐unit tax mechanism and an increasing block tax that only taxes units extracted above the social optimum. Another mechanism varies the observability of individual decisions. We find that the two tax and redistribution mechanisms reduce extraction, increase efficiency, and decrease inequality within groups. In contrast, observability impacts only the baseline condition by encouraging free‐riding instead of creating moral pressure to cooperate.     

Fair Income Tax

In a model where agents have unequal skills and heterogeneous preferences over consumption and leisure, we look for the optimal tax on the basis of efficiency and fairness principles and under incentive-compatibility constraints. The fairness principles considered here are: (1) a weak version of the Pigou–Dalton transfer principle; (2) a condition precluding redistribution when all agents have the same skills. With such principles we construct and justify specific social preferences and derive a simple criterion for the evaluation of income tax schedules. Namely, the lower the greatest average tax rate over the range of low incomes, the better. We show that, as a consequence, the optimal tax should give the greatest subsidies to the working poor (the agents having the lowest skill and choosing the largest labour time).     

Fairness in tax compliance: A political competition model

This paper analyzes the political economy of income redistribution when voters are concerned about fairness in tax compliance. We consider a two‐stage model where there is a two‐party competition over the tax rate and over the intensity of the tax enforcement policy in the first stage, and voters decide about their level of tax compliance in the second stage. We find that if the concern about fairness in tax compliance is high enough, a liberal middle‐income majority of voters may block any income redistribution policy. Alternatively, we find an equilibrium in which the preferences of the median voter are ignored in favor of a coalition formed by a group of relatively poor voters and the richest voters. In this equilibrium income redistribution prevails with no tax enforcement.     

Investment subsidies and redistributive capital income taxation in a neoclassical growth model

How do investment subsidies bear on pure redistribution when coupled with capital income taxes? In a heterogeneous agent, neoclassical growth framework it is found that on impact, with no optimizing behavior, investment subsidies are good for growth but bad for redistribution. The opposite holds for capital income taxes. But when the government acts as a Stackelberg leader vis-à-vis the private sector (the follower), the optimal feedback policy is by construction time-consistent and implies that in a long-run optimum the tax scheme does not distort accumulation. This holds regardless of social preferences. For the feedback Stackelberg equilibrium I find that (pure) redistribution can go either way and capital income taxes are nonzero in the long-run, time-consistent optimum, depending on the social weight of those who receive redistributive transfers, the distribution of pretax factor incomes, and the intertemporal elasticity of substitution. It is argued that investment subsidies may be an important indirect tool for redistribution, and may allow for the separation of “efficiency” and “equity” concerns.     

HETEROGENEITY AND REDISTRIBUTION: BY MONETARY OR FISCAL MEANS?*

In models with heterogeneous agents, issues of distribution and redistribution jump to the fore, raising the question: Which policies—monetary or fiscal—work most effectively in transferring income between groups? From Townsend's turnpike model, two basic results emerge to help answer this question. First, the zero lower bound on nominal interest rates often appears as an obstacle to redistribution by monetary means. Second, assumptions about the government's ability to raise tax revenue without distortion and to discriminate between agents in distributing that tax revenue play a large role in determining whether agents prefer to redistribute income by fiscal means instead.     

Money, Neutrality of Consumption Taxes, and Growth in Intertemporal Optimizing Models

This paper considers the effects of a proportional consumption tax with the same rate over time on the real growth path of a monetary economy. The analysis uses a variety of stylized monetary growth models in which the individual's consumption-saving decision is based on intertemporal utility maximization (e.g. the money-in-utility, transaction-costs, and cash-in-advance models). The neutrality of consumption taxation depends on the assumed role of money in the respective models, even though the tax revenue collected is fully rebated to consumers as lump-sum transfers. The consumption tax is generally superior to inflation tax (i.e. the rate of monetary growth) in terms of steady-state welfare, as long as the labour supply is fixed.

Help the Low Skilled or Let the Hardworking Thrive? A Study of Fairness in Optimal Income Taxation

In a model where agents have unequal wages and heterogeneous preferences, we study the optimal redistribution via an income tax, when the social objective is based on a combination of efficiency and fairness principles, and when incentive issues are taken into account. We show how some fairness principles entail specific features for the optimal taxes, such as progressivity or tax exemption for incomes below the minimum wage.     

Money or friends: Social identity and deception in networks

Strategic communication occurs in virtually all committee decision environments. Theory suggests that small differences in monetary incentives between committee members can leave deception a strategically optimal decision (Crawford and Sobel, 1982; Galeotti et al., 2013). At the same time, in natural environments social incentives can also play an important role in determining the way people share or withhold truthful information. Unfortunately, little is known about how monetary and social incentives interact to determine truth-telling. We investigate this issue by first building a novel model and then testing its equilibrium predictions using laboratory data. In the absence of social identity, the model׳s predictions are supported: there is more truthful communication between those who share monetary incentives than those who do not. We find that the effect of identity is asymmetric: sharing the same identity does not promote truth-telling but holding different identities reduces truthfulness. Overall, as compared to environments lacking social identity, committees with both monetary and social incentives exhibit truthful communication substantially less frequently.     

Work values,endogenous sentiments redistribution

We examine the interactions between individual behavior, sentiments and the social contract in a model of rational voting over redistribution. Agents have moral “work values”. Individuals' self-esteem and social consideration of others are endogenously determined comparing behaviors to moral standards. Attitudes toward redistribution depend on self-interest and social preferences. We characterize the politico-economic equilibria in which sentiments, labor supply and redistribution are determined simultaneously. The equilibria feature different degrees of “social cohesion” and redistribution depending on pre-tax income inequality. In clustered equilibria the poor are held partly responsible for their low income since they work less than the moral standard and hence redistribution is low. The paper proposes a novel explanation for the emergence of different sentiments and social contracts across countries. The predictions appear broadly in line with well-documented differences between the United States and Europe.     

Income distribution and tax structure: Empirical test of the Meltzer-Richard hypothesis

The Meltzer-Richard hypothesis that more unequal income distribution will create a majority for more redistribution has generated much research, but little empirical support. The empirical literature has concentrated on cross-country studies and the size of the public sector, and the results broadly do not indicate more redistribution with more inequality. This analysis suggests that the hypothesis should be investigated in a more homogenous setting with comparable institutions and with an explicit decision about redistribution (here tax structure). New data on poll tax and property tax in decentralized government in Norway are exploited. We show how the multi-dimensional decision can be analyzed as majority rule assuming intermediate preferences. In the econometric analysis, instruments are used to account for endogeneity of income level and income distribution. The estimated model supports the understanding that more unequal income distribution implies a shift in the tax burden from poll tax to property taxes and thereby gives more redistribution.     

Tax policy in the presence of emigration

This paper investigates the relationship between utilitarianism and horizontal equity in models of income taxation in particular and self-selection in general. An example involving well-behaved individual preferences is constructed in which a maximization of a utilitarian social welfare function leads via income taxation to horizontal inequities. Sufficient conditions for utilitarianism to bring horizontal equity are derived. The results are applied to the question of whether income tax credits are an appropriate way to treat differences in family size.     

The political economy of the impossible trinity

This paper reconsiders the policy trilemma in an open economy by incorporating political economy concerns. We argue that the impact of government ideology on monetary independence, exchange rate stability, and capital flow restrictions should be analyzed in the broader context of restrictions imposed by the impossible trinity instead of the usual single-dimensional constraints. Employing a de facto measurement of these restrictions for a sample of 111 countries from 1980 to 2010, we show that the impact of government ideology on a country's position in this trilemma is highly context dependent: we find that its impact on exchange rate stability and monetary independence varies between developed and developing countries. We also show that the impact of government ideology on these two trilemma components is contingent on the stance of the respective economy's business cycle. Left-leaning governments seem to favor exchange rate stability over monetary independence in case of a negative output gap; suggesting a reversal of their commonly assumed partisan preferences in economically tight times.     

Don't shoot yourself in the foot! A (real-effort task) experiment on income redistribution and voting

This paper reports results from a laboratory experiment that investigates the Meltzer–Richard model of equilibrium tax rates in which individuals are either low or high skilled workers and face a real-effort task that includes leisure at the work place. We find that a large proportion of low-skilled workers vote for the lowest tax rate (the one that gives them the lowest payoff), especially when the alternative tax rate is very high. However, this proportion is significantly reduced in treatments in which the subjects are given extra information about how the tax operates in redistributing income. This result suggests that the lack of information about the role of taxes in income redistribution may be an important factor in explaining the counter-intuitive voting behavior of low-income voters over income redistribution. We also find some support that the prospect of upward mobility and the belief in the negative effect of taxes on productivity make low-income voters support low tax rates, especially when the alternative tax rate is very high.     

Redistribution,taxes, and the median voter

We study a simple model of production, accumulation, and redistribution, where agents are heterogeneous in their initial wealth, and a sequence of redistributive tax rates is voted upon. Though the policy is infinite-dimensional, we prove that a median voter theorem holds if households have identical, Gorman aggregable preferences; furthermore, the tax policy preferred by the median voter has the “bang-bang” property.     

Redistributive taxation with heterogeneous relative consumption concerns

Abstract This paper studies the impact of redistributive income taxation in a society where only some individuals are motivated by relative consumption concerns. Introducing this heterogeneity raises theoretical challenges since (i) earned income becomes an imperfect indicator of underlying ability and (ii) relative concerns may be inadmissable in the social objective. A new behavioural model is developed in which only relatively‐concerned individuals choose work effort strategically. Linear tax/transfer systems schemes are then characterized and simulated for a series of welfarist and non‐welfarist social objectives, and for different degrees of preference heterogeneity. A key result is that a government which understands the extent of relative consumption concerns–but places no social weight on individuals with such preferences–nevertheless sets a significantly more progressive tax system than a government which ignores relative consumption motivations altogether.     

Inequality and the Relative Reliance on Tariffs

In this paper we uncover the existence of a U-shaped relationship between inequality and the relative reliance on tariff revenue, by estimating a cross-sectional regression relating the ratio of the tariff rate over the tax rate to inequality and a set of control variables such as GDP per capita, openness, the degree of democracy, and area dummies. We explain this U-shaped relationship by means of a Ricardian model of trade in vertically differentiated products between a developing country and the (developed) rest of the world. The model generates the U-shaped relationship because the preferences of the political majority (as captured by the median voter model) are shaped not only by the influence of inequality on the desire for redistribution, but also by the influence of inequality on the relative size of the tax base on which income taxes and tariffs are applied.     

Optimal Redistribution with Heterogeneous Preferences for Leisure

This paper examines the properties of the optimal nonlinear income tax when preferences are quasi–linear in leisure and individuals differ in their ability and their preferences for leisure. The government seeks to redistribute income. It can perfectly observe the level of endogenous income but cannot observe either ability or preferences. The heterogeneity of preferences leads to problems of comparability between individual utilities which challenge the design of redistributive schemes. We analyze the consequences of adopting a utilitarian social welfare function where the government is allowed to give different weights to individuals with different preferences. Under this particular social objective and given the quasi–linearity of preferences, we are able to obtain closed–form solutions for the marginal tax rates and to examine the progressivity of the tax system according to the weights used.     

Redistributive taxation in democracies: Evidence on people's satisfaction

Theories of political redistribution are tested using data collected in three phases of the International Social Survey Programme. Individuals categorized as having high, middle, or low incomes were asked whether they consider the overall tax burden in their countries too high, too low or about right. Very few citizens indicated that they were satisfied with tax systems; most believed that taxes on low and middle incomes are too high, while taxes on high incomes are too low. Support for tax systems is bimodal within the income classes, with the richest 5% being the most supportive, and the median in a population being second. Ideological values have a strong impact on political support for redistribution across all income classes. The results bear witness to the multidimensional nature of preferences for redistribution, and to the delicate question of the effectiveness of democracy in implementing citizens' preferences.     

Unconventional monetary policy and household debt: The role of cash-flow effects

We study the transmission of conventional and unconventional monetary policy shocks via the loan market, distinguishing between adjustable- and fixed-rate mortgages (ARMs and FRMs, respectively) and focusing on the relative importance of the income channel. Under ARMs, a conventional monetary policy shock implies a temporary cash-flow effect leading to a redistribution between savers and borrowers, a feature that is weaker, but more persistent, under FRMs. Also, an easing via unconventional operations – modelled as a shift in households’ preferences that reduces the term premium on long-term loan rates – has an expansionary effect on output and inflation, although more muted than the one recorded via a conventional monetary policy shock. In the former case, we find a modest contribution of cash-flow effect to the dynamics of consumption.
