Collective bargaining and regional wage differences in Spain: an empirical analysis

This article analyses the importance of labour market institutions and, in particular, collective wage bargaining in shaping regional wage differences in the Spanish labour market. Using microdata from the Spanish Structure of Earnings Survey, our results reveal that there are significant inter-regional wage differences for similarly skilled workers. These differences are present throughout the whole wage structure and can be explained by both competitive and non-competitive factors, such as insufficient competition in product markets. In this context, industry-level collective bargaining plays a major role in accounting for regional wage differences, a role that in the Spanish case is enhanced due to its unusual regional dimension.     

LABOUR‐MARKET ATTACHMENT AND TRAINING PARTICIPATION*

This paper examines how expected attachment to the labour market and expected tenure at a specific firm affect training participation. The results, based on cross‐sectional data from Japan, indicate that expected attachment to the labour market affects participation in both employer‐ and worker‐initiated training, while expected tenure at a specific firm mainly explains participation in employer‐initiated training. These two attachment indices explain more than two‐thirds of the sex gap in training participation. Employers in less‐competitive labour markets are more likely to offer employer‐initiated training to their workers.     

Labour Markets form the Microeconomic perspective: Implicit Contract Theory

This paper deals with a recent development in labour economics - that of implicit contract theory. A major impetus to its development has been the existence of involuntary unemployment and wage rigidity. In reality, there have been two streams of development - one associated with the name of Okun which focusses on the fixed costs of employing labour and the importance of reputation for reliability on the part of employers. The other emphasises differences in risk-aversion between employers and workers, viewing the implicit contract as a form of risk shifting. Both theories provide insights into the workings of labour markets, in particular, the pervasiveness of long-term employment relations. although difficulties arise in terms of the enforceability of contracts. The broader literature on internal labour markets in useful in this context.

'Young In,Old Out' Revisited: New Patterns of Employment Replacement in the Italian Economy

This paper, based largely on data from the Italian social security (INPS) records, shows that recent employment trends in Italy have been marked by large job and worker turnover and a new and strong process of renewal and substitution of labour in industry. Entries of young workers have shown a remarkable increase, mainly through the application of work and training contracts ('contratti di formazione e lavoro') that provide firms with a means to cut labour costs. Meanwhile many workers in their 40s with considerable seniority, but still perfectly fit to go on working, found themselves squeezed out. The exit of this generation of mature workers was eased through subsidised early retirement, golden handshakes and a wide application of the 'cassa integrazione guadagni' (wage supplementation fund). This pattern of labour force replacement in industrial production, described as 'young in, old out', is at odds with the frequent ranking of Italy among the industrial countries hampered by rigid labour markets and questions theories of unemployment based on 'insider-outsider' hypotheses.     

Firm-financed training: Firm-specific or general skills?

In this article we analyse the specificity and generality of firm-financed training in Norway. Compared to most other OECD countries Norway has a compressed wage structure. According to non-competitive theories of training we should expect to find much firm-sponsored training in such an economy, and furthermore we should expect to find relatively much firm-sponsored general training. The results in this paper suggest that firm-financed training in Norway contain much general skills. We find that training paid for by previous employers has a positive effect on current wages, and the effect is at least on par with the impact on wages from training paid for by the present employer. We use two methods to control for selection bias in training; an instrument variable (IV)-approach and a fixed-effect approach. The IV-approach suggests that the original training estimate is biased downward. However, our training variable may be subject to measurement error, and recent research has shown that the IV-estimate will be biased upward when a mismeasured variable is binary (as in our case). This finding receives support when using a fixed-effect approach. The IV-estimate for training considerably exceeds the fixed-effect estimate. The fixed-effect estimate is also lower than the original OLS-estimate indicating that some selection bias in training is present.First revision received: January 2002/Final revision received: October 2003The paper is financed by grant 108728/510 from the Norwegian Research Council.

No-arbitrage, state prices and trade in thin financial markets

We examine how non-competitiveness in financial markets affects the choice of asset portfolios and the determination of equilibrium prices. In our model, potential arbitrage is conducted by a few highly specialized institutional investors who recognize and estimate the impact of their trades on financial prices. We apply a model of economic equilibrium, based on Weretka (, 2007a), in which price effects are determined endogenously as part of the equilibrium concept. For the case in which markets allow for perfect insurance, we argue that the principle of no-arbitrage asset pricing is consistent with non-competitive behavior of the arbitragers and extend the fundamental theorem of asset pricing to the non-competitive setting.     

Training opportunities in monopsonistic labour markets

This paper studies the empirical relationship between the extent of monopsonistic power observed in occupational labour markets and the training opportunities available to workers in those markets; using data from the American National Longitudinal Survey of Youth of 1979. The results reveal a positive and significant association between monopsony power and training availability. The estimated association is found to be stronger for individuals with a college degree, with longer tenure in their jobs, and higher wages. These results are consistent across several econometric specifications that control for time, occupation, and individual fixed effects.     

Barriers to entry, deregulation and workplace training: A theoretical model with evidence from Europe

We study the impact of regulatory barriers to entry on workplace training. We develop a model of training in imperfectly competitive product and labour markets. The model indicates that there are two contrasting effects of deregulation on training. As stressed in the literature, with a given number of firms, deregulation reduces the size of rents per unit of output that firms can reap by training their employees. Yet, the number of firms increases following deregulation, thereby raising output and profit gains from training and improving investment incentives. The latter effect prevails. In line with the predictions of the theoretical model, we find that the substantial deregulation in the 1990s of heavily regulated European industries (energy, transport and communication) increased training incidence.     

Testing for fixity of the labour input under non competitive behaviour in Italian and French manufacturing

The flexibility in labour markets and the degree of competition in output markets are investigated in the context of the Italian and French manufacturing sectors. Conventional wisdom seems to point out that in countries with institutional constraints in the labour market it may not be easier to optimize over labour than over capital. We test whether labour is fixed starting with a measure of labour as total hours worked. As the hypothesis cannot be rejected, we do not proceed to test a further hypothesis, based on the measurement of labour as number of workers. We use a variable cost model supplemented with a markup pricing rule to allow for non competitive market structure. From the results it emerges that the output markets are non competitive. We derive analytically and provide a measurement of both short-run and intermediate-run markups. We also derive a measure of the long-run cost-minimizing level of labour: the ratio of optimal to actual level gives the degree of under- or over-utilization of labour.     

Financial markets,the structure of long-term investments and labour income risks

The paper develops a model to analyse the feedback between financial markets, long-term capital investments and the risk of labour incomes. We study a situation where firms are owned by entrepreneurs, who are able to share and diversify their income risk by trading on financial markets. Workers, in contrast, cannot short-sell the flows from future labour endowments and thus do not have the same opportunities. We derive two central results. Firstly, even if financial markets offer perfect risk-sharing opportunities for entrepreneurs, the participation restriction for labour incomes leads to a constrained inefficient market allocation. The constrained inefficiency arises because the effect of long-term investments on the risk of wages is not internalized by state prices. Secondly, we show that in general it is not true that workers indirectly benefit when we go from a situation with no financial markets to a situation with perfect financial markets for entrepreneurs but restricted participation for workers. The results suggest that a policy solution might require either to close some financial markets or to create new ones. We argue why there is a strong case for the creation of new markets rather than for closing existing ones.     

Labour market segmentation and union wage gaps

Abstract

There has been a great deal of research regard the effects of unions on union – non-union wage gap. Most of the studies regarding the impact of unions on wages have assumed that apart from the division between union and non-union workers, the labour market is relatively homogeneous. A number of economists, however, have argued that the labour market is segmented, implying that there are distinct labour markets and that some workers employment opportunities are concentrated in “bad jobs” while other workers employment opportunities are concentrated in “good jobs” which are rationed.

This paper will explore whether the relative wage differential between union and non-union workers differs between the independent primary, subordinate primary and secondary labour markets. Labour market segments are defined using “job zones”. “Job zones” are distinct groups defined by the level of specific vocational preparation necessary for a particular occupation, allowing for the comparison of skill levels and training for each occupation. The data on “job zones” comes from the Occupational Information Network database (O?Net). We estimate separate equations for union and non-union workers in each segment using data from the Current Population Survey and calculate union non-union differentials for each labour market segment. The findings of this paper suggest that the greatest differentials are in secondary labour markets followed by differentials in the subordinate primary labour market and that the smallest wage differentials are in the independent primary labour market.     

Detecting policy effects with wage rigidity and instability – evidence on the Taiwan labour market

With stagnant wages and growing productivity, a widening gap is becoming prevalent in global labour markets. The relationship between wages and productivity has become indeterminate, especially after the 2008 financial crisis. This article presents the phenomenon for why salary rarely follows up with productivity after an economy recovers. By using the GMM method, this study shows the interaction among wage, productivity and tightness, in which we illustrate the Taiwan labour market as an example to show how hiring system changes press wages away from an efficient allocation, causing instability and market failure. Surveying 35 labour markets for different industries, we reveal that the situation in the labour markets has drastically changed since 2008. We find that this resulted in a severe problem when the Taiwan firms got used to policies like ‘22K’, ‘fix-term contract’ and ‘unpaid leave’ programmes. These plans negatively impacted the economy and raised market failure with instability.     

Canadian regional labour market evolutions: a long-run restrictions SVAR analysis

Canada's high reliance on commodities can work against its constitutionally mandated goal of regional equity in economic development, while also inhibiting macroeconomic performance and limiting monetary policy effectiveness. Yet, flexible and integrated regional labour markets can help achieve both equity and macroeconomic goals. Therefore, this study examines the dynamics of Canadian provincial labour markets using a long-run restrictions structural vector autoregression (SVAR) model. Labour market fluctuations are decomposed into the parts arising from shocks to labour demand (new jobs), labour supply through migration (new people) and internal labour supply (original residents). The results suggest that demand innovations primarily underlie provincial labour market fluctuations. Despite significant geographic and language barriers that could impede their performance, there also is little overall evidence to suggest that provincial labour markets are more sluggish or less flexible than US state labour markets. Finally, original residents benefit slightly more from increased provincial labour demand compared to findings for US states.     

Optimal Factor Taxation under Wage Bargaining: A Dynamic Perspective

Abstract. We consider the issue of steady-state optimal factor taxation in a Ramsey-type dynamic general equilibrium setting with two distinct distortions: (i) taxes on capital and labour are the only available tax instruments for raising revenues and (ii) labour markets are subject to an inefficiency resulting from wage bargaining. If considered in isolation, the two distortions create conflicting demands on the wage tax, while calling for a zero capital tax. By combining the two distortions, we arrive at the conclusion that both instruments should be used, implying that the zero capital tax result in general is no longer valid under imperfectly competitive labour markets.     

SYNCHRONISING DEREGULATION IN PRODUCT AND LABOUR MARKETS

Deregulation typically comes with redistribution of rents and thus with opposition from the losing interest groups. We show that, by exploiting complementarities, synchronising deregulation across markets makes this opposition lower. Indeed, a particular deregulation may reduce rents for one interest group, but may result in gains for another interest group. Synchronising reforms can therefore offer a way out of the ‘sclerosis’ of especially European markets. For this effect, we build a microeconomic model based on two assumptions: Cournot competition à la Vives in the product markets and firms hiring workers in accordance with an efficiency wage in the labour markets. As being particularly relevant for European economies, we focus on product market regulation that determines the degree of market integration and labour market regulation that determines the degree of employment protection.     

The disintegrating Canadian labour market? The extent of the market then and now

Abstract.  Analysis of real wages for three occupations in 13 Canadian cities for 1901–50 suggests Canada had a national labour market at least until 1950. However, analysis of real wages for 10 Canadian cities for 1971–2000 yields little evidence favouring integration of Canada's regional labour markets. The apparent lack of labour market integration reflects a weakness of an approach that assumes markets are in equilibrium. Unemployment rates after 1970 suggest that some regional markets may be characterized by excess labour supply. Analysis of relative provincial unemployment rates yields evidence consistent with local labour force adjustment to changing labour market conditions. JEL classification: E24, J61     

Unemployment,long-term employment relations and the determination of unit labour cost growth in US manufacturing industries

This paper examines the effect that unemployment and long-term employment relations exert on the determination of unit labour costs. The paper proceeds in three sections. Section one analyses the relationship between labour market conditions and unit labour costs by developping a simple model of a firm that relies upon dismissal threats to elicit work effort. The comparative static properties of this model suggest that a tightening of labour markets may result in an increase in unit labour costs. In addition, it is argued that the labour market disequilibrium that occurs at full employment levels of unemployment will likely result in an increase in the growth rate of unit labour costs. The second section of the paper reviews diverse theories of long-term employment relations (LTERs), each of which suggest that the presence of LTERs ought to reduce the effect that labour market conditions exert on unit labour costs. The third section of the paper presents empirical estimates of the effect unemployment and LTERs exert on unit labour costs. The central empirical findings can be briefly summarized. First, movements towards full employment increase the growth rate of wages, reduce the growth rate of labour productivity and increase the growth rate of unit labour costs. Secondly, where long-term employment relations are prevalent, the effect of unemployment on wage, labour productivity, and unit labour cost growth is diminished. The paper concludes by discussing the implications these findings have for effort regulation models and the macroeconomic foundations of microeconomic labour market structures     

Labour market implications of EU product market integration

European labour markets are in a state of flux due to the changing market situation induced by international integration. This process affects wage formation through more fierce product market competition and increased mobility of jobs. This development is by some observers taken to enforce labour market flexibility, while for others it signals an erosion of social standards and in turn possibly the welfare society. Since labour is not very mobile in Europe, the effects of international integration on labour markets are mostly indirect via product market integration. We review the channels through which product market integration affects labour markets and perform an empirical analysis of the convergence and interdependencies in wage formation among EU countries. We find that integration is changing labour market structures and inducing wage convergences as well as stronger wage interdependencies, but it is a gradual process. Moreover, the present study does not support the view that international integration will lead to a 'race to the bottom' and rapidly erode domestic labour markets standards, nor that it will relieve politicians of the need to consider labour market reforms to improve labour market performance.
