In this paper, we address the issue of optimalenvironmental taxation under imperfect competition.The problem is analysed for three different types ofduopoly models, the Cournot open and closed loopmodels, and the Stackelberg model. We explicitlyanalyse the role of strategic behaviour. Each firm hasto make a choice of output level and of the level ofa strategic variable. The choice of this strategicvariable affects both marginal cost and emissions. Wecompare the properties of these three duopoly models,and derive and compare optimal environmental taxes. Weshow that whether the optimal tax is lower or higherthan marginal environmental costs depends on theinformation transmission and the effect of thestrategic variable on marginal costs. In addition, thedifferences in market shares, and the influence of thetax on the cost structure play important roles, indetermining optimal emission taxes. 相似文献

This study introduces a retirement decision into the classic Merton model. A familiar result is that you should retire if and when the marginal utility of another year's wages is equal to the disutility of work. A new result is that at the point of retirement your exposure to risky assets should not jump. Under power utility and constant time preference, the retirement timing problem has a closed form solution; the nine inputs to the formula in question give rise to nine comparative-static results on retirement timing. Further specialization of preferences, to log consumption utility and zero time preference, reduces the required number of inputs to four.

In order to be eligible for in-work tax credits, it is often not enough to have low earnings. In Ireland, New Zeand the United Kingdom, for example, for eligibility, it is also required that the number of hours worked is sufficiently high. Similarly, in Belgium and France, the hourly wage rate must be sufficiently low. In this paper, I provide a justification for such additional conditions. I analyze Pareto-efficient redistribution from high to low ability individuals in a model where labor has several intensive margins. Besides labor hours, labor effort – a vector of unpleasant, but productive features of labor – is also an object of choice. Effort and ability determine the hourly wage rate. I find that conditional subsidies on earnings for low earners are optimal: the earnings of low earners should be subsidized at the margin, but only if they earn more by working more hours at a sufficiently low wage rate. 相似文献

In this paper fiscal policy is examined for an open economy characterized by unemployment due to efficiency wages. We allow for capital and firm mobility in a model where the government chooses the level of wage, source-based capital and profit taxation. The taxing choices of governments are analyzed in scenarios which differ with respect to the constraints imposed on the set of available taxes and on the mobility of firms. As a general result, the welfare loss from labor market imperfections increases when tax bases become internationally mobile, which suggests an increasing relevance of domestic labor-market reforms when tax bases become global. 相似文献

This paper addresses optimal taxation, when therelationship between the consumption of a`dirty' good and the resulting environmentaldamage is uncertain and treated as a randomvariable by policy makers. The main purpose isto analyze how increased uncertainty, measuredas a mean preserving increase in the spread ofthis random variable, affects the optimalcommodity tax on the dirty consumption good. Incase the only task of government is to correctthe environmental externality, and if thepreferences are characterized by nondecreasingabsolute risk aversion, we find that thecommodity tax on the dirty consumption goodincreases in response to additionaluncertainty. If, on the other hand, thegovernment provides a public good and uses alump-sum tax in addition to the commodity tax,it is possible that the commodity tax decreasesas a response to additional uncertainty, evenif the preferences are characterized bynondecreasing absolute risk aversion. A similarresult emerges, although for different reasons,if the lump-sum tax is replaced by a laborincome tax. 相似文献

The existing instruments for improving the competitive balance within a sports league, such as revenue sharing, restrictions on free agency and salary caps, all have their shortcomings. In this paper, we show that a progressive sports tax, the revenues of which are not redistributed to smaller teams in the league, could be a better instrument. From the broader perspective of the theory of optimum taxation, this instrument may have advantages as well. 相似文献

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. 相似文献

Using an overlapping generations model in which human capital accumulation has positive external effects on the production
of the human capital of future generations, this paper analyzes implications of agents’ having preferences for educational
status, represented by human capital holdings relative to the social average. Examining the value and sign of the optimal
distortionary tax in the optimal taxation scheme, we analyze the efficiency of the level of human capital accumulation in
a decentralized economy. The desire for educational status can compensate for insufficient accumulation of human capital stemming
from human capital externalities directed toward future generations. 相似文献

We explore the implication of the `doubledividend' debate for international environmentaltaxes. In our scenario, small open economies withdifferent labor market distortions follow a commonenvironmental policy and use national environmentaltax revenues to finance labor tax cuts. Since thedouble dividend hypothesis does not hold, a high labortax implies a low environmental tax relative to othercountries. The optimal differentiation ofinternational environmental taxes is proven to be afunction of the national labor tax rates and theuncompensated elasticities of labor supply. 相似文献

The paper studies optimal forest taxation under uncertainty about future timber price when private forest owners value amenity services of forest stands and forest stands have public goods characteristics. It is assumed that preferences of forest owners can be described by a quasi-linear, intertemporal utility function which reflects risk aversion in terms of consumption and constant marginal utility in terms of amenity services. The comparative statics of current and future harvesting in terms of timber price risk, site productivity tax and yield tax are first developed. It is shown that, given the optimal site productivity tax, which is independent of the timber harvested and thus non-distortionary, it is desirable to introduce the yield tax at the margin; it both corrects externality due to the public goods characteristic of forest stands and serves as a social insurance device. The optimal yield tax is less than 100% and depends on the social value of forest stands, timber price risk and properties of compensated timber supply. In the general case the 'inverse elasticity rule – according to which the optimal yield tax is negatively related to the size of the substitution effects – may not hold. Under certainty, the desirability of the yield tax, given the optimal site productivity tax, depends only on the existence of public goods characteristic and is thus a pure Pigouvian tax. 相似文献

Intergenerational transfers are introduced into a general equilibrium life-cycle model in order to explain observed levels of wealth heterogeneity. In our overlapping generations model, heterogenous agents face uncertain lifetime and leave both accidental and voluntary bequests to their children. Furthermore, agents face stochastic employment opportunities. The model is calibrated with regard to the characteristics of the US economy. Our results indicate that bequests only account for a small proportion of observed wealth heterogeneity. The introduction of an inheritance tax increases both welfare, as measured by the average lifetime utility of a newborn, and equality of the wealth distribution.

This paper investigates optimal emissions taxation under imperfect competition in a durable good industry where products are sold (instead of rented). As a benchmark, attention is paid to the special case of monopoly with exogenously given product durability. In line with previous literature, the optimal emission tax in this benchmark model falls short of marginal damage (underinternalization). Extending the benchmark model either to the case of an oligopolistic market structure and/or to the case of endogenous product durability then provides two cases in which the optimal emission tax overinternalizes marginal damage. 相似文献

In the coming decades, the share of people of working age will fall significantly in most developed countries. According to optimal taxation theory, public debts should be reduced before the baby‐boom generation retires. I find that if debts are instead maintained at current levels, welfare may be reduced substantially in countries with a large public sector and/or a large demographic change. Since population aging will be less dramatic in the United States than in Europe and Japan, capital will move from Europe and Japan to the United States. These capital movements will facilitate the US demographic transition but aggravate the transition in most European countries. 相似文献

This article aims to theoretically clarify two points. First, even though the government shows favouritism to the poor and wants to exempt low-income taxpayers and to secure the necessary income tax revenue by taxing only high-income taxpayers, the government nevertheless ends up taxing the poor. This is in opposition to favouritism and arises because of the government’s inability to observe the individual taxpayer’s income levels. Second, even without observing each taxpayer’s income level, if favouritism is sufficiently strong, then the government can discontinuously resolve such unintentional taxation. 相似文献

When a government is unable to commit to its future tax policies, information about taxpayers' characteristics revealed by their behavior may be used to extract more taxes from them in the future. We examine the implications of this ratchet effect for the design of redistributive income and savings tax policies in a two‐period model with two types of individuals who only differ in their skill levels. When commitment is not possible, it may be optimal to separate, pool, or partially pool different types in period one. The nature of the distortions to labor supplies and savings are investigated for each of these three regimes. The identification of the optimal regime is investigated numerically. 相似文献

Empirical studies of household saving remain inconclusive about the role of bequest motives. This may be due to the diluting effect of different tax regimes across countries and time on estimates of bequest motives. Relative to market‐based economies, the former German Democratic Republic can be viewed as an experimental institutional setting where life‐insurance demand was not influenced by tax considerations. This allows isolating bequest motives from other life‐cycle and precautionary savings motives. Analyzing the demand for life insurance, we find a significantly higher ownership probability among households with children and a high regard for the family, confirming bequest motives in life‐insurance demand. 相似文献

This paper studies optimal taxation in a version of the neoclassical growth model in which investment becomes productive within the period, thereby making the supply of capital elastic in the short run. Because taxing capital is distortionary in the short run, the government׳s ability/desire to raise revenues through capital income taxation in the initial period or when the economy is hit with a bad shock is greatly curtailed. Our timing assumption also leads to a tractable Ramsey problem without state-contingent debt, which can give rise to debt-financed budget deficits during recessions. 相似文献
