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.     

International factor mobility,informal interest rate and capital market imperfection: A general equilibrium analysis

This paper makes an attempt to provide a theory of determination of interest rate in the informal credit market in a less developed economy in terms of a three-sector static deterministic general equilibrium model. There are two informal sectors which obtain production loans from a monopolistic moneylender and employ labour from the informal labour market. On the other hand, the formal sector employs labour at an institutionally fixed wage rate and takes loans from the competitive formal credit market. We show that an inflow of foreign capital and/or an emigration of labour raises (lowers) the informal (formal) interest rate but lowers the competitive wage rate in the informal labour market when the informal manufacturing sector is more capital-intensive vis-à-vis the informal agricultural sector. International factor mobility, therefore, raises the degrees of distortions in both the factor markets in this case.     

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.     

Capital tax,minimum wage,and labor market outcomes

Often an increase in the minimum wage is accompanied by a reduction in the capital tax. This paper analyzes the effects of interactions between the minimum wage and the capital tax in the general equilibrium framework. The analysis is conducted in an inter-temporal search model in which firms post wages. A (binding) minimum wage provides a lower support for the distribution of wages. The paper finds that the interaction of these two policy instruments significantly modify labor market outcomes and welfare cost. In the presence of a binding minimum wage, a decrease in the capital tax leads to an increase in wage dispersion. In contrast, when it is not binding, a lower capital tax may reduce the dispersion in wages. A binding minimum wage magnifies the positive effects of a lower capital tax on labor supply, employment, and output. It also enhances the welfare cost of capital tax. A policy change which involves an increase in the minimum wage and a fall in the capital tax such that employment level remains constant increases welfare and output.     

Optimal tax progressivity in unionised labour markets: What are the driving forces?

In labour markets with collective wage bargaining higher progressivity of the labour income tax creates a trade-off. On the one hand, wages are lowered and unemployment decreases, on the other hand, the individual labour supply decision is distorted at the hours-of-work margin. The optimal level of tax progressivity within this trade-off is determined using a numerical general equilibrium model with imperfect competition on the goods market, collective wage bargaining and a labour-supply module calibrated to empirically plausible elasticity values. The model is calibrated to macroeconomic and institutional parameters of both the OECD average and a number of individual OECD countries. In most cases the optimal degree of tax progressivity is below the actual level. A decomposition approach shows that the optimal level is increased by high unemployment and by the general tax level.     

Optimal Factor Income Taxation in the Presence of Unemployment

According to conventional wisdom internationally mobile capital should not be taxed or should be taxed at a lower rate than labour. An important underlying assumption behind this view is that there are no market imperfections, in particular that labour markets clear competitively. At least for Europe, which has been suffering from high unemployment for a long time, this assumption does not seem appropriate. This paper studies the optimal factor taxation in the presence of unemployment which results from the union-firm wage bargaining both with optimal and restricted profit taxation when capital is internationally mobile and labour immobile. In setting tax rates the government is assumed to behave as a Stackelberg leader towards the private sector playing a Nash game. The main conclusion is that in the presence of unemployment, the conventional wisdom turns on its head; capital should generally be taxed at a higher rate than labour.     

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.     

Skilled–unskilled wage inequality,product variety,public input and increasing returns: A static general equilibrium analysis

The paper develops a four sector small open economy model with two traded final good sectors, a public intermediate good producing sector and a nontraded good sector producing varieties of intermediate goods. There are three primary factors: capital, skilled labour and unskilled labour. Industrial sector producing a traded good uses capital, intermediate goods and skilled labour as inputs. Intermediate goods producing sector also uses capital and skilled labour. Public input producing sector and the agricultural sector producing the other traded good use capital and unskilled labour as inputs. It is shown that, if production technologies are the same for the agricultural sector and the public input producing sector and if the scale elasticity of output is very low, then an increase in capital stock (unskilled labour endowment) raises (lowers) the skilled–unskilled wage ratio. However, an increase in skilled labour endowment does not produce any unambiguous effect. On the other hand, an increase in the tax rate on industrial output and/or an increase in the price of the agricultural product, armed with the same set of assumptions, lowers the skilled–unskilled wage ratio.     

Effect of the Tax System ON R&D Intensity,Growth, Wages and Consumption Share

We propose a general equilibrium knowledge‐driven (semi‐)endogenous‐growth model with horizontal R&D, which is extended to consider two types of labour, skilled and unskilled, and exogenous government expenditure, financed through taxes on financial assets and on labour income, to analyse the implications of the tax system on R&D intensity, economic growth, wage inequality and consumption share in the output. In particular, we show that: (i) taxes have negative influence in the consumption share, being higher the marginal effect of the labour‐income tax; (ii) for any given government expenditure share, an increase (a decrease) in financial‐assets tax decreases (increases) the labour‐income tax; (iii) only the financial‐assets tax affects negatively the R&D intensity and the skill‐premium; thus, to reduce the skill‐premium the financial‐assets tax must increase; (iv) ignoring the effect on wage inequality and on R&D intensity, taxes are substitutes.     

Wage formation during economic transformation: macroeconomic facts and firm survey evidence from Slovenia

This article provides macroeconomic stylised facts on wage comparisons and microeconomic evidence on how institutional changes, competitive pressures in firms' output markets, human capital and efficiency wage payment affect wage formation during the early stages of transformation. Wages in Slovenia are higher than in other transition Central and Eastern European countries and higher than labour productivity. We use a firm survey panel dataset of Slovenian enterprises to investigate labour cost adjustment and its policy relevance. The results reveal that transformation was not a uniform process as it has induced different labour cost adjustments and wage responses to transformation shocks over time. The hypothesis that labour productivity and competitive pressures in firms' output markets were important for wage formation was not supported. We confirm that rent seeking increased wages in insider, management and employee-owned enterprises in anticipation of privatisation. The effect of human capital was modest and efficiency wage payment was found not to be significant. The hypothesis of unionisation in Slovenian enterprises was not supported.     

Macroeconomic impacts of fiscal policy shocks in the UK: A DSGE analysis

This paper develops and estimates a new-Keynesian dynamic stochastic general equilibrium (DSGE) model for the analysis of fiscal policy in the UK. We find that government consumption and investment yield the highest GDP multipliers in the short-run, whereas capital income tax and public investment have dominating effect on GDP in the long-run. When nominal interest rate is at the zero lower bound, consumption taxes and public consumption and investment are found to be the most effective fiscal instruments throughout the analysed horizon, and capital and labour income taxes are established to be the least effective. The paper also shows that the effectiveness of fiscal policy decreases in a small open-economy scenario and that nominal rigidities improve effectiveness of public spending and consumption taxes, whereas decrease that of income taxes.     

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.     

Capital income taxation when inherited wealth is not observable

This paper extends the Atkinson-Stiglitz model of direct and indirect taxation to a dynamic setting with two unobservable characteristics: productive ability and inherited wealth. Bequests are motivated by the ‘joy of giving’. A child’s inheritance is a random variable with a probability distribution that depends on his parent’s investment in a ‘bequest technology’. Public borrowing is assumed and implies the modified golden rule. We study the optimal tax policy when two instruments are available: a non-linear (wage) income tax and a proportional tax on capital income. We show that the second instrument ought, in general, to be used but that the tax rate is not necessarily positive. However, a positive tax rate is more likely when there is a positive correlation between inherited wealth and innate ability.     

Shadow pricing of labour and capital in an economy with unemployed labour

This paper derives the shadow prices of labour and capital to be used in the public sector in a situation of unemployment. The setting considered is that of a three-good, two-period general equilibrium model. Then shadow prices are compared to their corresponding market prices and shown to closely depend on own and cross-elasticities of supply and demand for labour and investment. In the first part, a rigid wage rate is the sole source of distortion; then, a tax on capital income is introduced so that our formula for the social rate of discount can be contrasted with that of Harberger, Sandmo and Drèze.     

Economic Reforms and Gender-Based Wage Inequality in the Presence of Factor Market Distortions

A simple three-sector general equilibrium model has been developed with both male and female labour and factor market distortions. The effects of different liberalized economic policies have been examined on the gender-based wage inequality. The analysis finds that credit market reform and tariff reform produce favourable effects on the wage inequality while the liberalized investment policy becomes counterproductive. The basic model has been extended to treat domestic capital differently from foreign capital. In the extended model, all of the above results hold. Additionally, it has been found that domestic capital formation is likely to produce a favourable impact on the gender wage inequality. These results have important policy implications for a small open developing economy.

     

Segmented labour markets and the estimation of wage functions

This paper uses a stratified random sample of private sector employees to estimate wage equations for both the male labour market as a whole and six ‘segments’ of the labour market, segement which are defined with respect to the industry and size characteristics of the employing establishmen. Highly conventional results are obtained when wage equations are estimated for the male labour market as a whole, or within two segements, comprising almost half the survey population. However, one can reject conclusively the hypothesis that the same estimating equation is appropriate for modelling wage determination in all segments and if a ‘human capital’ (HK) model is, within segements, tested against more appropriate alternative hypotheses for wage determination using the Davidson and Mackinnon (1981) methodology for the testing of non-nested hypotheses, the conclusion is that one should reject the HK specification and not reject the alternative.

It is therefore argued that the disaggregation of labour market data reveals differences in the wage determination process that are not consistent with the view that labour markets are ‘dualistic’ but are consistent with the view that are segmented.     

Compulsory Superannuation and Labour Market Responses

Compulsory contributions to superannuation have significant second round effects on labour market outcomes. The effects of employer, employee and government contributions are compared and contrasted for markets with different degrees of wage flexibility. With a flexible wage, the market wage adjusts to offset most of the initial effects of the superannuation levies. However, compulsion means that many employees perceive the present value of the future retirement income to be less than the levy. The levies as a form of tax on labour lead to lower overall remuneration for employees and lower employment     

Endogenous factor market distortion, risk aversion, and international trade under input uncertainty

In the context of non-diversifiable and sector-specific risks in labour markets, we show that the resulting factor market distortion – attributable to an endogenous intersectoral wage differential – can provide a possible rationale that explains why larger wage dispersion prevails in developing nations. We also demonstrate how endogenous wage distortions spill over to capital markets, with capital-poor economies offering lower rates of returns. In addition, we show that inequality in the distribution of wealth further deviates factor allocation away from first-best and impairs intersectoral mobility of the poor.
Ce mémoire montre que la distorsion dans le marché des facteurs qui résulte de risques non diversifiables et spécifiques à certains secteurs (et qui se traduit par un différentiel de salaire endogène entre secteurs) peut expliquer pourquoi on observe une dispersion plus grande des salaires dans les pays en voie de développement.On montre aussi comment des distorsions endogènes de salaires débordent vers les marchés de capitaux,ce qui fait que les pays pauvres en capital ont des rendements plus faibles.De plus, on montre que l'inégalité dans la distribution de la richesse contribue à faire dévier l'allocation des ressources de son optimum de premier ordre et nuit à la mobilité inter-sectorielle des pauvres.     

ENVIRONMENTAL POLICY AND LABOUR MARKET IMPERFECTION

This paper will set up a general equilibrium model with a distorted labour market to explore the effects of an environmental tax and union bargaining power on formal employment and the informal competitive wage. We find that when the government raises the environmental tax, both formal employment and informal competitive wage would fall. In addition, we confirm that a policy of labour market reform would increase both formal employment and the informal competitive wage.     

The NAIRU reconsidered: why labour market deregulation may raise unemployment

According to the mainstream theory of equilibrium unemployment, persistent unemployment is caused mainly by ‘excessive’ labour market regulation, whereas aggregate demand, capital accumulation and technological progress have no lasting effect on unemployment. We show that the mainstream non‐accelerating inflation rate of unemployment (NAIRU) model is a special case of a general model of equilibrium unemployment, in which aggregate demand, investment and endogenous technological progress do have long‐term effects. It follows that labour market deregulation does not necessarily reduce steady‐inflation unemployment. Theoretically, if the decline in real wage growth claims owing to deregulation is smaller than the ensuing decline in labour productivity growth and in the warranted real wage growth, then in that case steady‐inflation unemployment may increase. Empirical evidence for 20 Organisation for Economic Cooperation and Development (OECD) countries (1984–1997) indicates that the impact of labour market deregulation on OECD unemployment is zero, and possibly negative (causing a higher rate of unemployment).
