Accountability and fiscal equalization

A common feature of multi-jurisdictional systems is equalization programs. The implementation of such programs, that is based on some measurement of sub-national fiscal capacity and effort, is particularly complex. Within a political economy model, this paper analyzes the impact of such systems on accountability, identifying a positive and a negative effect. The positive effect arises because with equalized fiscal resources, a consequence of equalization, citizens attach more importance to any remaining variation in public good supplies and so punish rent-taking more severely. This induces politicians to restrain themselves and so accountability improves. The negative effect arises because the complexity of such programs reduces the informational content of observed public good supplies. This introduces a perverse fiscal incentive that reduces accountability. Thus, the overall impact of equalization programs on accountability depends on the balance of these effects.     

Competing in taxes and investment under fiscal equalization

The paper considers a model of federation with two heterogeneous regions that try to attract the capital by competing in capital income taxes and public investment that enhance the productivity of capital. Regions' choices determine allocation of capital across the regions and their revenues under a tax sharing scheme. This framework allows for the examination of different approaches to fiscal equalization schemes [Boadway, R., Flatters, F., 1982. Efficiency and equalization payments in a federal system of government: a synthesis and extension of recent results, Canadian Journal of Economics 15, 613-633; Weingast, B.R., 2006. Second Generation Fiscal Federalism: Implication for Decentralized Democratic Governance and Economic Development, Working Paper, Hoover Institution, Stanford University]. We show that tax competition distorts (downwards) public investments and that the equalization grants discourage public investments with a little effect on equilibrium taxes. However, the equalization schemes remain beneficial not only for the federation and, under a low degree of regional asymmetry, also for each region.     

Public goods,voting, and growth

We study a parametric politico‐economic model of economic growth with productive public goods and public consumption goods. The provision of public goods is funded by a proportional tax. Agents are heterogeneous in their initial capital endowments, discount factors, and the relative weights of public consumption in overall private utility. They vote on the shares of public goods in gross domestic products (GDP). We propose a definition of voting equilibrium, prove the existence and provide a characterization of voting equilibria, and obtain a closed‐form solution for the voting outcomes. Also we introduce a “fictitious” representative agent and interpret the outcome of voting as a choice made by a central planner for his benefit. Finally, we undertake comparative static analysis of the shares of public goods in GDP and of the rate of balanced growth with respect to the discount factors and the preferences for public consumption. The results of this analysis suggest that the representative‐agent version of our model is capable of capturing the interaction between many voting heterogeneous agents only if the heterogeneity is one‐dimensional.     

Public goods provision,inequality and taxes

The impact of redistributive policies on voluntary contributions is still not well understood. While a higher level of redistributive taxation decreases the price of voluntary giving, it also changes the income distribution by decreasing income inequality. This paper provides a controlled laboratory experiment to investigate the net impact of the tax rate on public goods provision. The experimental findings show that while the participants decrease their voluntary contributions as the pre-tax income distribution becomes more equal, they increase their contributions with taxation. These findings have important implications for government policies regarding privately provided public goods.     

Public goods, merit goods, and the relation between private and government consumption

In this paper, we investigate the relation between public and private consumption, by constructing a general government spending data set, by function, for 12 European countries. In particular, we split government consumption into two categories. The first category—“public goods”—includes defence, public order, and justice. The second category—“merit goods”—includes health, education, and other services that could have been provided privately. Equations from a relatively general permanent income model are estimated by GMM. The estimates are fairly robust in showing that public goods substitute while merit goods complement private consumption. However, the relation between merit goods and private goods turns out to be stronger than that between public goods and private goods. Thus, in the aggregate government and private consumption are complements.     

Public goods and joint supply

An example is presented which illustrates how analysis of the core of an economy can be used to clarify the debate between Demsetz and Samuelson on the relationship between public goods and joint supply. The core converges to the competitive allocation in an economy with joint supply but the core of a public goods economy does not converge to the Lindahl allocation. The example should prove useful as a pedagogic device, serving as a simple introduction to the technical literature on the core of an economy with public goods.     

Public goods and public bads

In many empirically relevant situations agents in different groups are affected by the provision of a public characteristic in divergent ways. Whereas for one group it represents a public good, it is a public bad for another group. Applying Cornes and Hartley's aggregative game approach, we analyze a general model in which such contentious public characteristics are present and are provided cooperatively. In particular, we establish neutrality results with respect to redistribution and growth of income, infer the effects of preference changes and coalition formation, and present a technology paradox. Finally, we compare the outcome of voluntary provision of the contentious public characteristic with the Pareto‐optimal solution, highlighting a potential conflict between equity and efficiency in this case.     

Consuming your way to efficiency: Public goods provision through non-distortionary tax lotteries

We revisit the classical result that taxation of private consumption is distortionary and therefore precludes the efficient provision of public goods. We introduce a nonlinear consumption tax which we call a ‘tax lottery’. Under this scheme, an ad-valorem consumption tax is supplemented with a lottery in which consumers can win cash prizes. The winning probabilities in this lottery depend on all consumers' private good consumption decisions. We show that for a given ad-valorem tax, an appropriately designed lottery can implement an efficient allocation in pure-strategy Nash equilibrium. The lottery component corrects the distortion in private consumption due to the ad-valorem tax, while the resulting tax revenue is sufficient to efficiently provide the public good and pay out the lottery prize.     

Public goods provision,redistributive taxation,and wealth accumulation

This paper presents an extension of a static model of public goods provision with redistributional taxation, as described by Uler [Journal of Public Economics 93 (3–4), pp. 440–453], as a dynamic model of wealth accumulation. Intertemporal consumption and saving behavior strongly affect the relation between redistributive taxation and charitable contribution. Indeed, the analyses presented herein reveal that more patience (i.e. higher saving) engenders a lower redistributional tax rate. However, the optimal redistributive tax rate is not zero because redistributive taxation improves the efficiency of providing public goods that are not improved by balanced growth. This paper fills the gap separating static analysis and dynamic analysis, and generalizes the results presented by static analysis.     

Public debt accumulation and fiscal consolidation

In this study, we analyse the relationship between interest rates on government bonds (GB) and the fiscal consolidation rule by using an overlapping generation model with endogenous and stochastic growth settings. Our key findings are summarized as follows. First, contrary to conventional view, we find that interest rates on GB may decline as public debt accumulates relative to private capital. Second, the simulation reveals that the economy may exhibit discrete changes with divergent interest rates, implying that the observed trend of relatively low interest rates on GB with public debt accumulation may not continue indefinitely in the future. Third, fiscal consolidation rule plays a key role in determining equilibrium interest rates.     

The incentive effect of fiscal equalization transfers on tax policy

A theoretical analysis considers the impact of a typical system of redistributive “fiscal equalization” transfers on the tax effort of local jurisdictions. More specifically, it shows that the marginal contribution rate, i.e. the rate at which an increase in the tax base reduces those transfers, might be positively associated with the local tax rate while the volume of grants received is likely to be inversely related to the tax rate. These predictions are tested in an empirical analysis of the tax policy of German municipalities. In order to identify the incentive effect the analysis exploits discontinuities in the rules of the fiscal equalization system as well as policy changes. The empirical results support the existence of an incentive effect, suggesting that the high marginal contribution rates induce the municipalities to set significantly higher business tax rates compared with a situation without fiscal equalization.     

Public goods with congestion

I consider the problem of the efficient provision of a congested (limited capacity) public good in a setting with asymmetric information. I show, in particular, that when the capacity of the good is limited, in a wide class of economies it is possible to construct an incentive compatible mechanism that always produces the good at the efficient level, balances the budget and satisfies voluntary participation constraints. This result is in contrast with the corresponding impossibility result for pure public goods due to Mailath and Postlewaite (Rev. Econ. Stud. 57 (1990) 351-359) and Rob (J. Econ. Theory 47 (1989) 307-333).     

Public goods in networks

This paper considers incentives to provide goods that are non-excludable along social or geographic links. We find, first, that networks can lead to specialization in public good provision. In every social network there is an equilibrium where some individuals contribute and others free ride. In many networks, this extreme is the only outcome. Second, specialization can benefit society as a whole. This outcome arises when contributors are linked, collectively, to many agents. Finally, a new link increases access to public goods, but reduces individual incentives to contribute. Hence, overall welfare can be higher when there are holes in a network.     

Public consumer goods, output-generated variable returns, and labor supply

This paper develops a simple general-equilibrium model of a closed economy. The economy under consideration produces two final goods, one private and one public, which are both produced with labor and an intermediate good under constant returns to scale. The intermediate good is produced by labor alone, and its production is subject to output-generated variable returns to scale. The public good can be interpreted as government spending on environmental quality, police protection, cultural activities, and publicly funded health care. The model is used to examine the impact of an exogenous change in labor supply on the size of the government, relative prices, and welfare. Within the context of the present study, an increase in labor supply can be attributed to either exogenous immigration or population growth. The model is also used to examine the relationship between the size of the country and the pattern of trade.     

Public goods provision and redistributive taxation

This paper studies the relationship between redistributive taxation and tax-deductible charitable contributions. Redistribution has two opposite effects on voluntary giving. The price of charitable giving decreases with the degree of redistribution, and this has a positive effect on the total amount of giving (substitution effect). However, redistribution leads to lower consumption for the contributors and therefore has a negative effect on contributions to the charity (income effect). The theoretical model developed in this paper demonstrates that, under a general class of utility functions, the substitution effect dominates the income effect. Hence, charitable giving increases with the tax rate. In purely egalitarian societies, the public good is provided efficiently and the total welfare is maximized independent of the ex-ante income inequality. However, the positive impact of taxation on charitable giving and welfare may disappear if individuals generate their income levels in anticipation of taxation and redistribution does not take into account the cost of effort.     

Public budget composition,fiscal (de)centralization,and welfare

Abstract We study the optimal degree of fiscal decentralization in a dynamic federal economy where governments decide on budget size and its allocation between public education and infrastructure spending. We find that full centralization of tax and expenditure policies is optimal when infrastructure productivity is similar across regions. When differences are not too large, partial centralization is optimal. With strong differences, full decentralization becomes optimal. National steady‐state output tends to be highest under full decentralization. We provide a justification for the mixed evidence regarding the Oates conjecture by showing that full dominates partial decentralization, despite being inferior to complete decentralization.     

Public intermediate goods and distortionary taxation

In the Pigovian tradition, when public intermediate goods are financed by distortionary taxation, expenditure should not be carried so far as to equate the sum of the marginal productivities with the marginal cost. This paper shows how this rule may break down when commodity taxes are used to finance public intermediate goods.
