Temporary employment and segmentation in the Spanish labour market: An empirical analysis through the study of wage differentials

We aim to add empirical evidence to the already studied field of wage differentials between temporary and permanent workers in Spain. Our goal is to find out which determinants of wage differentials are relevant when explaining such differences. Furthermore, the endogeneity of such feature (the type of contract) is controlled for. The same exercise is done with two data sets: the ECHP and the Structure of Earnings Survey. Results show that wage differentials between temporary and permanent workers are explained by the differences in the distribution of personal and job characteristics in both groups, but not by differences in the rewards for those characteristics. These results remain mostly unchanged during the second part of the 1990s, using information from five waves of the ECHP, and are robust to different changes in the econometric specification.JEL Classification: J31, J41The authors would like to thank the participants in the 3rd Summer School of Labour Economics (organised by IZA in Amersee, Munich), in a seminar in the University of Alcalá and in another seminar in the European University Institute in Florence and especially Alison Booth, Luis Toharia, Juan F.

An empirical analysis of patents flows and R&D flows around the world

In this article, we empirically investigate the effect of Research and Development (R&D) flows on patent flows around the world. We do this using an unbalanced panel consisting primarily of Organization for Economic Co-operation and Development (OECD) countries that have both patent and R&D expenditure information broken down by domestic and foreign sources. Our analysis shows that even among a fairly homogeneous group of countries, the sources of patents and R&D differ substantially. Using a dynamic panel framework, we find that domestic R&D per capita increases domestic patents per capita only for the European Patent Convention (EPC) countries that already have a decentralized approach to innovation. Foreign R&D per capita increases foreign patents per capita in all countries even though foreign R&D constitutes a very small fraction of total R&D. We find that some of these differences can be attributed to the locations of the patent applications, including those to the European Patent Office (EPO), United States Patent and Trademark Office (USPTO) and triadic patent applications to the EPO, USPTO and Japan Patent Office (JPO) simultaneously.     

An iteration process for calculating labour market flows

This article presents a technique for calculating labour market flows, given labour market stocks of workers and nonemployed agents at the beginning and at the end of a certain period of time. I build a system of equations that define the stocks as a product of the flows. For a vector of stocks Y and a vector of flows X, the system of equations is defined as Y = A*X. However, the system is not solvable (the flows cannot be identified) due to singularity of the matrix A. I suggest an iteration process that enables us to solve the system and identify the flows given a chosen negligible deviation from the true flows.     

Culture and labour productivity: An empirical investigation

Culture is considered as one of the most powerful forces that shape human behaviour and thereby economic activity. This paper investigates the effects of culture on labour productivity and examines the cultural traits driving this relationship. Using panel data analysis, empirical evidence is provided covering a sample of 34 OECD countries over a wide period of three decades. Our empirical results suggest a significant positive relationship between the cultural background and labour productivity. The main channels of this positive impact are control and work ethic environment, while obedience has a negative impact on productivity. These findings are robust to a series of robustness checks, including alternative cultural measures, additional control variables, various country samples, and alternative specifications.     

The minimum wage and the Lithuanian labour market

This paper presents a comprehensive and non‐standard labour market analysis based on univariate and multivariate models for wages. The novelty of this paper lies in the use of non‐normalized cointegrating vectors for labour market analysis. Wages are the basis of labour market models, as well as the key factor for employees and employers; therefore, the central analytical axis is a classical wage bargaining process, where one side requires and the other side proposes a certain level of wages. Analysis is divided into two parts: foremost, a careful analysis of Lithuanian wages is conducted and a univariate model for the investigation of interactions between the minimum wage and the rest of the wages is proposed; only after the minimum wage model is drafted can the multivarate model for the whole economy be built up. Briefly, the methodology used in this article can be annotated as a synthesis of sequential theoretical and empirical considerations that combine the results of theoretical macroeconomics with data‐generating patterns and stylized facts. The model is considered as the final one only if macro‐theory preconditions, statistical prerequisites, and stylized real‐world requirements are met and fulfilled. In addition, this article gives an example and a quantitatively, as well as qualitatively, motivated suggestion as to how to incorporate minimum wages into econometric models and puts forward an explanation for why it is necessary to include minimum wage dynamics into labour market analysis. The article is nothing but an empirical case study that demonstrates how many minor details have to be taken into account until a realistic labour market model is built up. Although the paper deals with the labour market, the suitable application of time series methods is the main subject of the analysis.     

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.     

The incidence and intensity of wage indexation: an empirical analysis

Variables suggested by theoretical studies of indexation are considered with a view to examining their utility in the context of the decision to index (incidence) and the desired degree of indexation when escalator clauses are put into effect (intensity). The Tobit model, which can address both of these issues, suggests that most of the effects of explanatory variables on the regressand occur by modifying the incidence of indexation, not its intensity. However, the Tobit model is itself rejected in favour of separate Probit and Truncated Regression investigations of incidence and intensity, respectively. The results obtained indicate that the standard list of explanatory variables, which one thinks of in the context of the theoretical literature as dealing primarily with intensity, perform well in explaining incidence but very poorly in accounting for the non-limit observations. The latter are influenced by bargaining power proxies such as the unemployment rate and union density; a very clear trade-off between indexed and non-contingent wage adjustment can also be discerned. These results call for more theoretical attention to the distinction between indexation incidence and its intensity.     

An empirical test of the segmented labour market theory for the Netherlands

In this paper an orthodox segmented labour market theory (SLM theory)is tested by means of the data provided by the research project, Quality of Labour 1977 (Zanders et al., 1977). The segmented labour market theory is restricted to the dual labour market approach, although a major extension is taken into account (a primary segment consisting of two tiers). The segments are created by making use of an objectivemethod. Nine quality characteristics of jobs are taken into account. A number of logit estimations are carried out to test the competing theories of human capital and the segmented labour market. The conclusion is that although discrimination in the labour market appears to exist, the SLM theory has to be rejected.     

A regional analysis of flows into and out of the UK national minimum wage

This article utilizes the panel element of the UK Labour Force Survey (LFS) to identify for individual regions total inflows and outflows and hazards for those individuals paid at or below the National Minimum Wage (NMW). In particular, it examines the extent and direction of the correlation between low-pay inflows and outflows and the economic cycle. Further, it examines the impact of regional variations in the bite of the NMW on regional flows into and out of the NMW.     

Taxing capital flows: an empirical comparative analysis

Recent studies have analysed the impact of capital account opening on income growth, implicitly assuming that the various forms of foreign savings have similar effects. In fact, theoretical considerations suggest that the individual components of private capital inflows have different effects on growth. This paper analyses the link between income growth and private capital inflows. It presents system GMM estimates with annual observations from 1985 to 1996 for 72 countries. When full-sample results are checked for country and period changes, most of capital inflow series lose their ability to explain income growth. Bank flows stand as the sole source of foreign financing that displays a positive and robust correlation with growth.     

An empirical approach on labour segmentation. Applications with individual duration data

This article proposes empirical tools to account for the role of heterogeneities in the labour matching process, and shows an application to the Andalusian labour market which relies on individual data. The central idea of the paper is that the labour market is segmented, and this segmentation can be treated empirically by grouping workers, jobs and matches into labour groups according to their characteristics. In a segmented labour market the probability that a match occurs in a particular job group affects the probability that a match occurs in a particular worker group or vice versa. We propose two empirical measures related to this idea: propensity to match, and segmentation in worker and job groups. The usefulness of this empirical framework is shown by its application to different labour market analyses. Firstly, we use a clustering methodology, based on a similarity measure, to obtain a better overview of the structure of the labour market. Secondly, we propose a measure of mobility based on our similarity measure, and estimate a regression model that relates mobility to worker and job characteristics and to the economic cycle. Finally, these tools are included in an unemployment duration model. The proposed methodology may be useful in labour intermediation by helping seekers to follow a ‘roadmap’ of successful paths.     

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.

Economic liberalization and wage inequality in the presence of labour market imperfection

This paper is purported to analyze the consequences of liberalized economic policies on the skilled–unskilled wage inequality in the developing countries using a three sector general equilibrium model reasonable for at least a few developing economies. The analysis of the paper has found that the wage inequality rises unambiguously due to a reduction of import tariff from the low-skill manufacturing sector. However, an inflow of foreign capital produces a favourable effect on the wage inequality under a reasonable factor intensity condition. Interestingly, contrary to the common wisdom, a policy of labour market reform may raise the competitive unskilled wage and improve wage inequality under reasonable condition.     

The labour market and the distribution of earnings: an empirical analysis for Italy

Using four waves of data from the Participation Labour Unemployment Survey, a database of information on the Italian labour market supply, we address the question of earnings dispersion by applying a ‘nested’ decomposition procedure of the Theil inequality measure, which combines into a unified framework the standard decompositions by population subgroups and income sources. The empirical evidence obtained points to the key role played by the self-employees in shaping labour income inequality, especially at the upper extreme of the earnings distribution, and the emergence of non-standard forms of employment as an important feature of the contemporary workplace.     

Soviet postwar industrial growth and capital labour substitution: An empirical note

This note tests an aggregate transcendental production function for Soviet industry. The estimated equation shows the elasticity of substitution in aggregate Soviet industry in less than unity and it is decreasing quite rapidly.     

And the winner is... An empirical evaluation of unitary and collective labour supply models

An empirical evaluation is presented of two competing flexible labour supply models. The first is a standard unitary model, while the second is based on the collective approach to household behaviour. The evaluation focuses on the testing of the model’s? theoretical implications and on their ability to identify structural information, like preferences and the intrahousehold allocation process. Models are applied to Dutch microdata from the DNB Household Survey. The unitary model cannot be rejected for male and female singles, while it is rejected for a sample of couples. The alternative collective model cannot be rejected for the same sample, allowing identification of individual preferences and an intrahousehold sharing rule that can be used as a basis for welfare economic policy evaluations.     

An empirical analysis of margin debt

Despite the extensive literature on margin requirements and stock market volatility, few articles consider the determinants of margin borrowing. Our trivariate autoregressive model of margin debt, stock returns, and the broker call rate shows that margin debt responds positively to stock returns and negatively to interest rate changes over the period 1951–2001. We also document an asymmetry, with margin debt responding quickly to stock market downturns and more gradually to market upswings.
