The Level of Wage Bargaining as a Firm–Union Choice

There is a trade-off between central bargaining which allows local externalities to be internalized and local bargaining which gives firms and unions the scope to determine both wages and employment simultaneously and efficiently in the sense of McDonald and Solow (1981). A model of strong unions is presented where workers are also concerned with relative wages. The trade-off is resolved by the individual firm and union on the basis of choice, using the Pareto-criterion. In the presence of a small extra contract cost under local bargaining, the main findings are: (i) central bargaining is Pareto-optimal only for extreme values of the reservation income level—a change in unemployment remuneration may cause centralization to breakdown; and (ii) centralization may also be sustained as a suboptimal Nash-equilibrium through workers' concern with relative wages—the familiar Keynesian coordination failure.     

Unemployment, growth and taxation in industrial countries

To the layman, the upward trend in European unemployment is related to the slowdown of economic growth. We argue that the layman's view is correct. The increase in European unemployment and the slowdown in economic growth are related, because they stem from a common cause: an excessively rapid growth in the cost of labour. In Europe, labour costs have gone up for many reasons, but one is particularly easy to identify: higher taxes on labour. If wages are set by strong and decentralized trade unions, an increase in labour taxes is shifted onto higher real wages. This has two effects. First, it reduces labour demand, and thus creates unemployment. Secondly, as firms substitute capital for labour, the marginal product of capital falls; over long periods of time, this in turn diminishes the incentive to invest and to grow. The data strongly support this view. According to our estimates, the observed rise of 14 percentage points in labour tax rates between 1965 and 1995 in the EU could account for a rise in EU unemployment of roughly 4 percentage points, a reduction of the investment share of output of about 3 percentage points, and a growth slowdown of about 0.4 percentage points a year.     

Unions, progressive taxes, and education subsidies

Progressive income taxes moderate distortionary wage demands by trade unions and thereby reduce unemployment, and at the same time underlie disincentives to acquire skills and decrease labour productivity. Governments can respond by combining progressive taxes with subsidies to investment in human capital. A system of generous education subsidies and steep progressive tax rates is more likely to emerge, the greater the market power of trade unions and the better the ability of governments to influence private education decisions. Empirical analysis for several OECD countries provides results consistent with these propositions. A policy mix of high education subsidies and relatively progressive income taxes is found in countries where union membership is significant.     

Wage restraint and monetary union

Existing work on wage bargaining predicts more aggressive wage setting under monetary union. This is exemplified by Cukierman and Lippi (2001) who postulate that wages are set having area-wide prices in mind. The insight of aggressive wage behaviour has not been confirmed by the EMU experience, which has been characterised by wage moderation. The present paper investigates the possibility of wage restraint using a monetary union model which, realistically, assumes that trade unions set wages with national prices in mind. Drawing on plausible ranges for all parameter values (and macroeconomic shocks), our simulations show that a monetary union elicits real wages that are broadly comparable to those obtained under monetary autonomy. The confidence bounds around these results are rather wide, in particular including scenarios of wage restraint.     

Monetary Institutions,Monopolistic Competition,Unionized Labor Markets and Economic Performance*

Recent literature on the interactions between labor unions and monetary institutions features either a supply or a demand channel of monetary policy, but not both. This leads to two opposing views about the effects of central bank conservativeness. We evaluate the relative merits of those conflicting views by developing a unified framework. We find that: (i) the effect of conservativeness on employment depends on unions’ relative aversion to unemployment versus inflation, and (ii) for plausible values of this relative aversion (and more than one union), social welfare is maximized under a highly conservative central bank. We also evaluate the effects of centralization of wage bargaining and product market competition on unemployment and inflation.     

Fiscal adjustment and labor market dynamics in an open economy

This paper studies the labor market effects of fiscal adjustment in a two-sector, three-good intertemporal framework. Key features of the model are an informal sector, minimum wages, unionized labor in the formal economy, imperfect labor mobility, and public production of intermediate inputs. “Luxury” and wait unemployment prevail in equilibrium. It is shown that if unions care sufficiently about employment, and if the degree of openness is high, an increase in the price of government services may reduce unemployment in the steady state. A similar result would hold in an efficiency-wage setting if the “disciplinary effect” of unemployment is sufficiently strong.     

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

Employment and Wages in the Private and Local Government Sectors in a Centralized Fiscal System

This paper discusses the interaction between the local government and private sector in an institutional context consistent with a centralized fiscal system. Under decentralized wage setting in the private sector, the effects of shocks in the two sectors depend on whether private and local public goods are substitutes or complements in the union utility function. Higher wage markup in the local government sector unambiguously decreases government output while the effect on private sector employment is ambiguous. Higher income taxes have ambiguous effects on local government output. Shocks in the private sector can be reinforced through feedback effects from the local government sector. A shift from decentralized to centralized wage setting in the private sector reduces wages and increases employment in both sectors.     

Continuity and Change in Australian Wages Policy

Australia shares with several small European economies the characteristic of having a relatively coordinated union movement with the ability to influence real wage levels. This article explores the course of wages policy over the last decade by applying to Australia a model of wage determination originating in Europe, a model which assumes that the union movement can determine the real wage level. The wage level the union movement chooses is influenced by choices it faces between real wage increases and employment growth. The unions are also influenced by the public sector employment generating activity of government. Stagflation in the late 1970s is analysed by hypothesising a misperception by the union movement of the policy options available to government, and a mistrust by government of the unions' willingness to moderate wage increases if employment levels rise rapidly. The model suggests that an accord between unions and government (such as that which has been in place in Australia since 1983) is a way to escape some of these policy dilemmas.     

Involuntary Unemployment and Environmental Policy: The Double Dividend Hypothesis

An environmental tax reform might bring about gains over and above improved environmental quality. In particular, if tax revenues from environmental taxes are used to reduce the tax on wage income, positive employment effects can result in second-best economies. An efficiency wage model is used to analyze the impact of an ecological tax reform on involuntary unemployment. The government controls emissions by selling emission permits. Employment of labor and wages are determined endogenously. Conditions are identified under which an environmental tax reform reduces unemployment and increases welfare.     

REGIONAL UNEMPLOYMENT DISPARITIES: AN EVALUATION OF POLICY MEASURES*

This paper analyses the efficacy of regional and federal government policies in reducing inter‐regional unemployment disparities. We use as our framework a two‐region general equilibrium model with a given freely‐mobile supply of labour. We assume inter‐regional migration to occur in response to inter‐regional utility differentials. Each region has households, firms and a regional government. In addition to regional governments, there is a federal government. The firms in a region use a single factor, labour, to produce a single good which we assume to be different to that produced in the other region. It is supplied to households and to the regional government in the form of payroll taxes. Households consume some, trade some with households in the other region and give some up to the federal government as income tax. Firms and households bargain over wages and firms then choose employment to maximise profits. The resulting equilibrium will generally not be a full‐employment one. We simulate a linearised numerical version of the model. We examine seven alternative policies, six carried out by a regional government and one by the federal government. In the first group there are traditional tax/expenditure polices as well as policies which might be seen as attacking the natural rate of unemployment: changes in unemployment benefits, changes in union power, changes in the labour force and changes in labour productivity. The federal government policy is a regionally‐differentiated fiscal policy. Contrary to expectations, many policies which have traditionally been recommended to alleviate unemployment are found, in fact, to exacerbate the unemployment problem.     

A “Managerial” trade union and economic growth

By setting up a simple Romer-type [Romer, P.M., 1989. Capital accumulation in the theory of long-run growth. In: Barro, R.J. (Ed.), Modern Business Cycle Theory. Harvard University Press, Cambridge, MA] endogenous growth model embodying a political trade union (rather than the traditional economic labor union), this paper explores the effects of unionization on unemployment, growth and welfare by highlighting the essence of internal conflict within the union. It is shown that the conflicting interests between the leadership and membership within the union play a decisive role in the unemployment, growth and welfare effects of unionization. Given the fact that taxation is another potential candidate besides unions in explaining the poor performance of a macro-economy, we re-examine the taxation effects within the growth model with equilibrium unemployment caused by the presence of the trade union and compare our findings with those for the traditional full-employment growth model. In general, we find that the taxation effects of income and consumption crucially depend not only on the institutional arrangements for taxing unemployment benefits, but also on the way the government budget is balanced.     

What goes up sometimes stays up: shocks and institutions as determinants of unemployment persistence

We analyse the determinants of unemployment persistence in four OECD countries by estimating a structural Bayesian VAR with an informative prior based on an insiders/outsiders model. We explicitly insert unemployment benefits and labour taxes so that our identification is not affected by the Faust and Leeper (1997) critique. We find widespread hysteresis: demand shocks play a dominant role in explaining unemployment also in the medium‐run. Moreover real wages have low sensitivity to cyclical fluctuations and to labour market disequilibria. Our results emphasise the real power of the unions and their interactions with structural shocks and other institutions as crucial determinants of hysteresis.     

Unemployment insurance and union bargaining — an insider-outsider approach

A trade union is required to tax its own members to fund unemployment benefit paid to its unemployed members in an insider-outsider model of union bargaining over wages and employment. An increase in unemployment benefit imposed by the government increases employment overall but not necessarily the employment of insiders if the tax rate is exogenously fixed by the government.This paper has benefited from comments of Mick Common, Dipak Ghosh, Bob Hart, and Robin Ruffell. The comments of two anonymous referees and the advice of the Editor have greatly improved the presentation of the paper. Any remaining errors or omissions are the responsibility of the authors.     

Union wage setting and unemployment in the Netherlands (1965–1987)

This paper presents an empirical model of union wage setting and employment. The (Stackelberg) equilibrium unemployment rate is shown to be a function of taxes, the replacement ratio, the gap between consumer and producer prices, productivity effects, and the rate of long-term unemployment. The model is estimated with aggregate data from the private sector in the Netherlands (1965–1987). The results suggest that the equilibrium unemployment rate is pushed upwards by taxes, the replacement ratio and by the gap between consumer and producer prices, and is reduced by productivity effects. Insider-outsider effects appear insignificant.     

Macroeconomic shocks, unionized labour markets and central bank disclosure policy: How beneficial is increased transparency?

The paper investigates the implications of disclosure by the central bank to the private sector of information relating to the current realizations of macroeconomic disturbances. In the context of an economy in which the goods market is monopolistically competitive and where wages are set by atomistic unions, we find that greater precision of information provided to wage setters in respect of supply shocks has ambiguous welfare effects, both from the perspective of the social loss function and from the viewpoint of unions who act on the information. An important feature of the model is an externality in union wage setting which implies the outcome of the wage determination process is collectively inefficient.     

Index to Volume 52, 2000

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.     

Preferential trade agreements and tax competition for foreign direct investment

This paper examines how free-trade agreements and customs unions affect the location of foreign direct investment (FDI) and social welfare, taking into account that governments may adjust taxes and external tariffs to compete for FDI. Conditions are identified under which a free-trade agreement leads to FDI and under which this improves welfare. The welfare effect is shown to depend on the relative size of efficiency gains in production and government revenue losses due to tax competition. A free-trade agreement may fail to induce welfare-improving FDI, creating a role for a customs union.     

Labour Taxation in a Unionised Economy with Home Production

The impact of payroll taxes on unemployment and welfare are examined in a model with household production and union–firm wage bargaining. The analysis shows that unemployment typically falls as the payroll tax rate in the market sector for household substitutes (the service sector) is reduced. This holds even when the payroll tax rate in the non-service sector is raised in order to maintain a balanced government budget. Welfare improves with a reduced-service-sector payroll tax rate only if unions are equally strong and firms are equally labour intensive across the sectors.

Wages fund, high wages, and social conflict in a classical model of unemployment equilibrium

The aim of the paper is to provide an explanation of involuntary unemployment in a classical (post-Ricardian) framework. The model describes a three-stage bargaining process with four agents (governments, firms, unions, workers). In the first stage, firms determine the wage offered, following a short-run version of the wages fund theory. In the second stage, unionists determine the wage demanded, which depends on workers’ tendency to conflict, while firms decide the number of employed under a “right to manage” hypothesis. In the third stage, governments tax the wages fund and pay unemployment benefits. Public intervention is subject to a trade-off between accumulation and legitimation.
