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

does competition for capital discipline governments decentralization globalization and public policy competition among countries or regions within them to attract mobile capital is often thought to discipline their governments motivating them to invest more in infrastructure reduce waste and corruption and spend less on non productive public goods the result should be convergence on business friendly policies we argue that this requires an assumption units start out very similar that is often unrealistic if units are heterogeneous in natural resources geographical location inherited human capital or infrastructure capital mobility often weakens discipline on the poorlyendowed units this may help explain disappointing results of liberalizing capital flows within russia and sub saharan africa jel f36 h73 h87

why hasn t tax competition triggered a race to the bottom some quantitative lessons from the eu abstract the integration of european financial markets in the early 1980s created an environment of near perfect capital mobility across countries that had harmonized indirect taxes but maintained large differences in factor taxes the years that followed witnessed several rounds of competition in capital taxes with puzzling results instead of the dreaded race to the bottom in capital taxes the uk lowered its capital tax to a rate closer to those of france germany and italy while capital taxes changed slightly in these countries the uk increased its labor tax marginally but the other countries increased theirs sharply this paper shows that these results are consistent with the quantitative predictions of a dynamic neoclassical general equilibrium model of tax competition that incorporates the key international externalities of tax policy operating via relative prices wealth distribution and fiscal solvency tax competition is modeled as a one shot game over time invariant capital taxes with dynamic payoffs relative to a status quo calibrated to european data the calibration is preceded by an empirical analysis that shows that the relationship linking taxes to labor supply and the investment rate in the model are in line with empirical evidence and that domestic taxes seem to respond to foreign taxes the solutions of the games show that when countries compete over capital taxes adjusting labor taxes to maintain fiscal solvency there is no race to the bottom and the nash equilibrium is close to observed taxes in contrast if consumption taxes adjust to maintain fiscal solvency competition over capital taxes triggers a race to the bottom but this outcome entails large welfare gains surprisingly the gains from coordination are small in all of these experiments

a theory of interregional tax competition a general equilibrium model is constructed to study tax competition where local governments compete for capital by holding down property tax rates and public expenditure levels an exact definition of tax competition is provided and both the existence and nonexistence of tax competition are shown to be theoretically possible it is argued however that tax competition must occur under empirically reasonable conditions inefficiency in public production is also explicitly modeled the amount of capital used to produce a given level of public service output is shown to be greater than that which is required to minimize costs evaluated at the prices facing private firms

source versus residence based taxation with international mergers and acquisitions this paper analyses tax competition and tax coordination in a model where capital flows occur in the form of mergers and acquisitions rather than greenfield investment in this framework we show that differences in residence based taxes do not necessarily distort international ownership patterns moreover tax competition yields globally efficient levels of source based corporate income taxes if residence based taxes on capital income are absent in contrast in the presence of residence based taxes on dividends source based corporate income taxes are inefficiently high the widespread view that tax coordination is less urgent if residence based taxes are available may therefore be misguided

capital taxation and production efficiency in an open economy we attempt to clarify the role of the production efficiency theorem in international capital taxation it is shown that a direct open economy analogue to the production efficiency theorem arises not in the small country case but in the more general setting of tax competition between a finite number of identical jurisdictions

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

capital tax competition under a common currency abstract we re examine the view that capital taxes are too low when capital is mobile across tax jurisdictions we do so by emphasising a previously neglected implication of decentralised capital tax setting when jurisdictions share a common currency namely capital taxes give rise to a vertical externality by affecting the revenues of the over arching central bank from issuing the common currency this externality may lead ceteris paribus to too high regional capital taxes and may more than offset the usual effects of tax competition in this case and contrary to conventional wisdom decentralised capital taxes will be too high

determinants of the crude oil futures curve inventory consumption and volatility abstract since 2008 the wti oil futures curve has been positively sloped for extended periods we test whether changes in inventory alone can explain this atypically long contango to do this we estimate monthly vars of the cme wti oil futures spread and oecd and u s inventory in line with standard theory and add petroleum consumption and implied volatility to the vector of endogenous variables when we model the futures spread as one continuous series results confirm two way causation between inventory and the futures curve as predicted by the theory of storage however when we separate negative and positive futures spreads we find that two way causation between the futures spread and u s inventory breaks down shocks to oecd petroleum consumption cause more negative spreads and shocks to u s consumption cause more positive spreads in addition to inventory driven changes and increases in volatility directly raise positive spreads these new causal channels have become significant since 2008 and can be related to higher inventory inelastic supply of oil and uncertainty about global economic conditions

equilibrium capital taxation in open economies under commitment abstract this paper analyzes equilibrium capital taxation in open economies with strategic interaction in a neo classical growth model under perfect commitment i show that non cooperative capital taxes are zero in the long run for a large open economy thereby generalizing the result previously established only for the special cases of a closed and a small open economy this does not represent a race to the bottom though since the result is independent of the degree of capital mobility the number of countries or a country s size relative to the rest of the world moreover when countries cooperate they still set capital taxes to zero in the long run these outcomes are robust to different equilibrium specifications the inclusion of endogenous government spending and heterogeneous agents and non linear labor income taxation governments find it optimal to implement the efficient capital allocation in the long run both in a closed and an open economy this trumps incentives to tax foreigners domestic capital holdings by raising capital taxes and attracting capital from abroad by lowering capital taxes

strategic capital tax competition a pecuniary externality and a corrective device abstract d e wildasin journal of urban economics25 193 212 1989 identifies a source of inefficiency in capital tax competition models with price taking jurisdictions and provides a pigovian correction this paper identifies a second source of inefficiency in a non price taking environment when a jurisdiction increases its capital tax it affects the price of capital and thus other jurisdictions returns from trade in capital the pigovian correction to internalize this pecuniary externality is derived since a focus of recent research is on non price taking environments the existence of the pecuniary externality is important in qualifying existing results in the literature

dynamic optimal taxation in small open economies abstract this paper examines the effects of perfect capital mobility on the determination of optimal capital taxation it shows that capital movements do not change dramatically the optimal tax path studied for the closed economy in addition the paper provides a counterexample to the standard belief that the worldwide system is the optimal regime of taxation finally it shows that the rate of taxation of the rest of the world is not fundamental to determine the optimal decision of a small economy

does federalism lead to excessively high taxes the relative strengths of vertical and horizontal tax externalities turn on the balance between the interest responsiveness of the supply of savings and demand for capital the extent to which immobile factors are taxed by the states and the strength of preferences between federal and state expenditures the vertical externality will dominate if the aggregate tax base of the federation is responsible to the state tax instrument tax interactions in federations are more complex than has often been supposed

policy commitment and the welfare gains from capital market liberalization this paper evaluates the quantitative impact of capital liberalization on the taxation structure and welfare of the liberalizing countries when governments conduct fiscal policy optimally but without commitment time consistent policies the transition from a regime of capital autarky to a regime of free mobility leads to a decrease in the long term tax rate on capital of 13 percent and an increase in the tax rate on labor of 2 percent as a consequence of this taxation shift welfare increases by about 1 percent the reduction in capital taxation induced by capital market liberalization is welfare improving because in the absence of capital mobility the time consistent policies over tax capital

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

residence and source based capital taxation in open economies with infinitely lived consumers abstract in this paper we investigate tax competition in a neoclassical growth model where each country may use both residence and source based capital taxes we show that both types of capital taxes are zero at any interior steady state just as in a closed economy for symmetric countries and even for countries that differ only with respect to size and productivity we prove analytically and verify numerically that the open economy policies coincide exactly with the closed economy policies in all time periods for countries that are asymmetric in other dimensions we find that source based taxes are used to manipulate the intertemporal terms of trade in the short run either way the fiscal externalities of source based taxes vanish once residence based taxes are allowed

tax competition and leviathan abstract attitudes towards downward pressure on tax rates from international tax competition depend on attitudes towards government this paper synthesises the two extremes which as in other areas of public finance have dominated the debate typically being presented as stark alternatives the view of government as a leviathan from which tax competition emerges as a useful constraint on policy makers and the view of government as a benevolent maximiser of their citizens welfare from which it emerges as a source of inefficiency conditions are derived under which when policy makers are neither entirely benevolent nor wholly self serving tax coordination benefits the representative citizen

positive long run capital taxation chamley judd revisited according to the chamley judd result capital should not be taxed in the long run in this paper we overturn this conclusion showing that it does not follow from the very models used to derive it for the main model in judd 1985 we prove that the long run tax on capital is positive and significant whenever the intertemporal elasticity of substitution is below one for higher elasticities the tax converges to zero but may do so at a slow rate after centuries of high tax rates the main model in chamley 1986 imposes an upper bound on capital taxes we provide conditions under which these constraints bind forever implying positive long run taxes when this is not the case the long run tax may be zero however if preferences are recursive and discounting is locally nonconstant e g not additively separable over time a zero long run capital tax limit must be accompanied by zero private wealth zero tax base or by zero labor taxes first best finally we explain why the equivalence of a positive capital tax with ever increasing consumption taxes does not provide a firm rationale against capital taxation

optimal indirect and capital taxation we consider an environment in which agents skills are private information and follow arbitrary stochastic processes we prove that it is typically pareto optimal for an individual s marginal benefit of investing in capital to exceed his marginal cost of doing so this wedge is consistent with a positive tax on capital income we also prove that it is pareto optimal for the marginal rate of substitution between any two consumption goods to equal the marginal rate of transformation this lack of a wedge is consistent with uniform taxation of consumption goods within a period

pigou tiebout property taxation and the underprovision of local public goods abstract pigou s proposition that the use of distorting taxes rather than neutral head taxes reduces public service levels is examined in this paper a simple model with a national system of competing local governments is utilized to demonstrate that the use of a distorting property tax on mobile capital decreases the level of residential public services the case where public services are an intermediate producer good is also considered

redistribution fiscal competition and the politics of economic integration the paper examines the consequences of the economic integration of factor markets in a model with two countries that redistribute income among their residents the social benefits in each country are financed by a source based tax on capital which is democratically chosen by its inhabitants if either capital or labour is internationally mobile the countries engage in fiscal competition and the partial integration of capital or labour markets is detrimental to the countries redistributive ability a move from partial to full integration however may alleviate rather than intensify fiscal competition particularly if the two countries face sufficiently similar economic and political conditions in such a situation for example tax competition for mobile capital is softened as the labour market becomes more integrated and even vanishes if both factors are fully mobile as a result there is more redistribution in equilibrium and a majority of the population in each country is strictly better off copyright 2002 wiley blackwell

optimal capital income taxation in a small open economy abstract this paper considers a stochastic small open economy with a financial asymmetry between the households and the government in this setting it is optimal not to tax capital income beyond the initial period this is in contrast to the existing results for stochastic closed economies
