Welfare impacts of equal-yield tax reforms in the UK economy

A multisectoral dynamic general equilibrium tax model with and without announcement effects for open and closed capital markets is used to evaluate efficiency gains and transitional effects from equal-yield tax reforms for seven different taxes in the UK economy. Impacts of an unanticipated tax reform on investment, capital accumulation, output and employment are compared to those of anticipated tax reforms. Households, producers, traders, investors and the government are found to be more capable of adjusting their economic behaviour when tax announcements are made in advance. In equal-yield tax experiments welfare gains up to 1.4% of base year GDP can occur by removing distortions in taxes. Welfare loss of up to 2.05% of it can happen if a less distortionary tax, such as the labour income tax is replaced by more distortionary taxes. These simulation results hold whether the capital markets are closed or open.     

Employment- and growth effects of tax reforms

Since the mid-1990s almost all OECD countries have engaged in fundamental reforms of their tax systems. There is a trend towards higher social security contributions and lower tax rates on personal and corporate income. This paper explores whether these tax policy measures are effective means for reducing unemployment and accelerating economic growth. Using a Pissarides type search model with endogenous growth, we analyze how savings and the incentive to create new jobs are affected by revenue-neutral tax swaps between wage income taxes, payroll taxes, capital income taxes and taxes levied on capital costs. In our framework, cutting the capital income tax (reducing the double taxation of dividend income) financed by a higher payroll tax turns out to be superior, such a policy mix fosters both employment and growth. Most other tax reforms imply a trade-off between employment and growth.     

On Cost Benefit Rules for Green Taxes

This paper concerns the welfare effects of a green tax reform in a dynamic general equilibrium model with preexisting taxes on labor income and capital income. In comparison with previous studies on green taxes in dynamic models, which have focused their main attention on long run effects of such reforms, I derive cost benefit rules for a change in the tax mix by using the properties of the value function in optimal control theory. This enables me to relate the welfare effect of a change in the tax mix to responses in employment, the capital stock, (flow) emissions and the stock of pollution along the whole general equilibrium path. Another contribution of the paper is to examine under what conditions an emission tax, which is set permanently below the marginal damage of pollution, is welfare superior to an emission tax path that fully internalizes the external effect.     

Tax Liability and Tax Evasion in a Competitive Labor Market

In a competitive labor market, a change in the legal incidence of a tax on labor will not alter employment if tax obligations are fulfilled. However, this irrelevance result may no longer apply if taxes can be evaded. In particular, a shift from payroll to income taxes will lower employment. This will be the case if workers exhibit constant absolute risk aversion, have a utility function, which is strongly separable in income and the disutility from working, and the penalty for evasion is not proportional to the amount of taxes evaded. Accordingly, tax evasion opportunities can make the legal incidence of a tax on labor an important determinant of its economic incidence.     

Fiscal Policy,Economic Integration and Unemployment

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.

In an efficiency wage economy with variable profits, a shift from payroll to employment taxes will reduce unemployment if the tax level is held constant at the initial wage. However, unemployment will rise if firms are constrained to zero profits in the long run and if tax revenues are constant. This reversal of employment effects occurs because the shift in taxes reduces wages. This implies a budget deficit. Hence, taxes will have to be raised if revenues are held constant. If the firm's profits cannot change, the tax increase will cause some firms to close down and unemployment will rise. Thus, the predicted employment consequences of changes in the tax structure depend on assumptions about the time horizon and budget constraint.     

Possible Policies for Expansion

The Australian economy appears certain to be operating at well below full employment into 1992, or even longer. Further reductions in interest rates would operate on output only with long lags, and would be the most inflationary form of stimulus. But cuts in a wide range of indirect taxes, and tax incentives for new investment - especially if announced as temporary - would reduce the length and depth of the recession.
Results of simulations with macro-economic models for a number of countries imply that cuts in indirect taxes or in taxes on employment (either alone or in combination with other fiscal measures) reduce prices as well as stimulating employment and real output. Similar fiscal measures are likely also to improve the current account at any given level of employment or real output, and even more likely to increase the country's net wealth (private investment less the current account deficit).
Failure to adopt appropriate types of fiscal stimulus would reduce the benefits of microeconomic reform and make such reforms harder to achieve. Even if it were true that these forms of fiscal stimulus would not raise real output, the tax cuts in question would at least reduce inflation and could not then increase the current account deficit.     

Flat income taxation,redistribution and labour market performance

A flat tax rate on labour income has gained popularity in European countries. This article assesses the attractiveness of such a flat tax in achieving redistributive objectives with the smallest distortions to employment. We do so by using a detailed applied general equilibrium model for the Netherlands. The model is empirically grounded in the data and encompasses decisions on hours worked, labour force participation, skill formation, wage bargaining between unions and firms and a wide variety of institutional details. The simulations suggest that the replacement of the current tax system in the Netherlands by a flat rate will harm labour market performance if aggregate income inequality is contained. Only flat tax reforms that reduce redistribution will raise employment. This finding bolsters the notions from optimal tax literature regarding the equity-efficiency trade off and the superiority of nonlinear taxes to obtain redistributive goals in an efficient way.     

Border tax adjustments and tariff‐tax reforms with consumption pollution

We develop a model of a small open economy, where pollution per unit of consumption between domestically produced and imported quantities of the same good differs. We show that the first‐best policy combination calls for consumption taxes on all polluting goods, and border tax adjustment (BTA) measures, that is, tariffs or import subsidies. We identify conditions under which well‐known tariff‐tax reform policies for developing economies, such as a consumer‐price‐neutral piecemeal reform of trade and a consumption tax, and a consumer‐price‐neutral reform of all trade and consumption taxes improve welfare. We also evaluate whether reforms of trade taxes alone are superior to consumer‐price‐neutral reforms of trade and consumption taxes.     

Consequences of Environmental Tax Reform for Unemployment and Welfare

We investigate the welfare effects of environmental tax reform, i.e. raising environmental taxes and using the proceeds to reduce distortionary taxes on labour. The framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage. Environmental tax reform boosts not only environmental quality but also employment if substitution between labour and resources is easy, the production share of the fixed factor is large, and the initial tax rates on resources and profits are small. If the initial tax system is sub-optimal with a negligible tax on resources, profits rise as well.     

Piecemeal Reform of Domestic Indirect Taxes toward Uniformity in the Presence of Pollution: with and without a Revenue Constraint

The literature on indirect tax reforms in pollution‐ridden economies is quite limited. This paper, using a general equilibrium model of a perfectly competitive small open economy with both production‐ and consumption‐generated pollution, considers the welfare implications of tax reforms that take the structure of consumption and production taxes toward uniformity. Specifically, both in the presence and absence of a binding government revenue constraint, we derive sufficient conditions for welfare improvement in the case where we implement (i) reforms in either production or consumption taxes, and (ii) reforms in both consumption and production taxes.     

Growth,Employment and Taxation with Distortions in the Goods and Labour Market

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms.     

FIRING COSTS AND BUSINESS CYCLE FLUCTUATIONS*

This article considers a real business cycle model with establishment level dynamics and uses it to analyze the effects of firing taxes. It finds that firing taxes can have significant consequences on business cycle fluctuations, that the largest effects are on aggregate employment, and that even relatively small firing taxes have substantial effects. A significant contribution of the article is computational: It describes how to use standard linear‐quadratic methods to solve for a stochastic equilibrium of an (S,s) economy with tax distortions.     

Revenue‐enhancing Trade Liberalization in a Differentiated Duopoly

Existing studies suggest that in developing countries, tax reforms that increase consumption taxes can compensate for shortfalls in revenue from a tariff reduction. However, these revenue‐enhancing tariff–tax reforms have a critical shortcoming—they generally reduce welfare under imperfect competition. This paper shows that tax reforms such as consumption tax reforms do not necessarily have to be implemented to make up for revenue shortfalls from tariff reductions under imperfect competition, because trade liberalization through tariff cuts leads to an increase in government revenue when domestic and imported goods have a high substitutability. This revenue‐enhancing effect of a tariff reduction occurs for a wider degree of product substitutability when initial tariff and consumption tax rates are high. More importantly, we show that even if initial tariff and consumption tax rates are sufficiently low, a tariff reduction still increases government revenue for a low degree of product differentiation under Bertrand competition.     

Labor Taxation in Search Equilibrium with Home Production

Conventional models of equilibrium unemployment typically imply that proportional taxes on labor earnings are neutral with respect to unemployment as long as the tax does not affect the replacement rate provided by unemployment insurance, i.e. unemployment benefits relative to after–tax earnings. When home production is an option, the conventional results may no longer hold. This paper uses a search equilibrium model with home production to examine the employment and welfare implications of labor taxes. The employment effect of a rise in a proportional tax is found to be negative for sufficiently low replacement rates, whereas it is ambiguous for moderate and high replacement rates. Numerical calibrations of the model indicate that employment generally falls when labor taxes are raised.     

The impact of the 2008 German corporate tax reform: A dynamic CGE analysis

In this paper we develop the dynamic CGE model, ifoMod, which is designed to analyse the impact of fundamental tax reforms and in particular capital income tax reforms for Germany. The model is in line with neoclassical growth theory and features all important behavioural interactions between the four major building blocks of an economy including the firm and household sector, the government and the rest of the world. We consider firms of different legal forms which all face an intertemporal investment problem, a financing problem w.r.t. the optimal choice of debt and equity financing as well as a factor input problem when deciding on the optimal amount of different skill types of labour employed. We show the impact of different types of taxes on the behavioural margins of firms and households. The conducted simulation shows the impact of the latest German corporate tax reform of 2008 on the German macroeconomic variables such as investments, GDP, consumption and household's welfare.     

A structural VAR approach on labour taxation policies

This paper presents a Structural VAR analysis on the employment and output effects of labour tax policies in six European countries for the period 1974–1997. By considering impulse response functions, it turns out that, on average, a shock to the total personal income tax revenues is positively correlated to employment, whereas there is mixed evidence on the output effect. Moreover, the quantitative impact of these effects, especially those related to the output, appears to be quite small. However, by introducing explicitly four labour tax parameters (namely the marginal and average tax rates for the personal income tax and the payroll tax), it turns out that these effects are not negligible after all: for some countries it is possible to conceive labour taxes as policy instruments favouring more employment and a better economic performance. However, the empirical support on the sign of the output and employment effects is mixed, suggesting that the same domestic fiscal policy does not produce the same impact in all the European countries.     

Tax enforcement,tax compliance and tax morale in transition economies: A theoretical model

The focus of this paper is the analysis of the relationship between tax enforcement, tax compliance and tax morale within countries characterised by rapid introduction of market institutions and slow evolution of political regimes, such as transition economies. The paper investigates a coordination game in which the government is ex-ante committed to tax enforcement and can observe the proportion of tax-compliant agents in the economy. In turn, two groups of agents (third-party reporting and self-reported income) are keen to evade taxes unlawfully but have limited information on how many others evade taxes; their tax morale is therefore an endogenous function of agents' perception on tax compliance. The model predicts that the lower the quality of political institutions and the weaker tax morale, the less tax compliance can be achieved. The third-party reporting group will also be bearing higher tax burden than the self-reported income group. The model entails that having political institutions of good quality is not a sufficient condition to conduce to tax enforcement or tax compliance. Due to the endogenous role of tax morale, the government could be pushed ex-post towards poor or no tax enforcement. If good political institutions are not accompanied by good information about the enforcement of tax collection, there is scope for co-existence of poor tax enforcement, low tax compliance and weak tax morale. As such, this model well describes the tax evasion behaviour observed since the outset of transition from planned to market economy.     

Tax Reform,Structural Unemployment and the Environment

The effects of environmental tax reform, i.e., using the proceeds of a higher energy tax rate to lower the labour tax rate, on wage formation, employment and environmental quality are analysed in the context of a small open economy with structural unemployment caused by hiring costs. We find that such a reform may boost employment if it shifts the tax burden away from workers towards those without employment in the formal sector. Environmental tax reform succeeds in shifting the tax burden away from workers in the formal sector if higher energy taxes reduce earnings in the informal sector by reducing labour productivity.     

Green Tax Reform and Competitiveness

This paper studies a revenue-neutral green tax reform that substitutes energy for wage taxes in an open economy with unemployment. As long as the labour tax rate exceeds the energy tax rate, such a reform will increase employment, reduce the domestic firms' unit cost of production and hence increase international competitiveness and output of the economy. The driving force behind these results is the technological substitution process that a green tax reform will bring about. The resulting reduction in unemployment is welfare increasing since energy, which the country has to buy at its true national opportunity cost, is replaced with labour, whose price is above its social opportunity cost.
