Contract employment policy and research productivity of knowledge workers: an analysis of Spanish universities

Abstract

This article investigates how contract employment practices adopted by universities—fixed-term contracts and permanent contracts—impact research productivity measured in terms of publications in scholarly journals. The empirical application considers the Spanish public higher education system for the period 2002–2008. We report an inverse U-shaped relationship between the rate fixed-term contracts and the research productivity of Spanish universities. That is, contract policies based on fixed-term contracts are conducive to research productivity; however, beyond a critical threshold value increases in the proportion of fixed-term contracts are associated with declining research productivity. These findings reveal that contract employment policies shape research productivity, and that flexible and balanced contract practices are critical for enhancing universities’ research productivity. The results suggest that the excessive use of fixed-term contracts might create an unstable working environment that limits the universities’ capacity to capitalize on their knowledge workers. Policy implications and future research avenues are discussed.     

How binding are legal limits? Transitions from temporary to permanent work in Spain

This paper studies the duration pattern of fixed-term contracts and the determinants of their conversion into permanent ones in Spain, where the share of fixed-term employment is the highest in Europe. We estimate a duration model for temporary employment, with competing risks of terminating into permanent employment versus alternative states, and flexible duration dependence. We find that conversion rates are generally below 10%. Our estimated conversion rates roughly increase with tenure, with a pronounced spike at the legal limit, when there is no legal way to retain the worker on a temporary contract. We argue that estimated differences in conversion rates across categories of workers can stem from differences in worker outside options and thus the power to credibly threat to quit temporary jobs.     

The part-time pay penalty in a segmented labor market

This paper is the first to examine the implications of switching to PT work for women's subsequent earnings trajectories, distinguishing by their type of contract: permanent or fixed-term. Using a rich longitudinal Spanish data set from Social Security records of over 76,000 prime-aged women strongly attached to the Spanish labor market, we find that the PT/FT hourly wage differential is larger and more persistent among fixed-term contract workers, strengthening the existent evidence that these workers can be classified as secondary. The paper discusses problems arising in empirical estimation (including a problem not discussed in the literature up to now: the differential measurement error of the LHS variable by PT status), and how to address them. It concludes with policy implications relevant for Continental Europe and its dual structure of employment protection.     

Wage Growth Implications of Fixed-Term Employment: An Analysis by Contract Duration and Job Mobility

Focusing on Spain, where fixed-term workers account for a third of the wage and salary workforce, we examine the wage growth implications of fixed-term employment of varying duration while distinguishing between wage growth occurring on-the-job versus via job mobility. Wage growth among employees with indefinite work contracts largely occurs via job mobility, whereas fixed-term workers gain via job mobility as well as on-the-job. Consequently, job stayers with fixed-term contracts a year ago narrow their wage gap with respect to similar counterparts with indefinite-term contracts. Yet, this effect is solely driven by the 10.5 percentage points higher wage growth experienced by fixed-term workers with 6-months contracts able to keep their jobs beyond their initial contract period. Given the limited number of short-term temporary workers in those circumstances, the overall wage gap between past fixed-term and indefinite-term workers is unlikely to vanish in the near future.     

The Fading Attraction of Central Regions: an Empirical Note on Core–Periphery Gradients in Western Europe

Abstract

This paper describes sectoral core–periphery gradients across Western European regions over the period 1975–2000, and it estimates the impact of EU membership on countries’ internal geography. Overall, it is found that the centrality of European regions has been losing importance as a determinant for the location of employment. Central regions have gained employment share in none of the eight broad sectors analysed, whereas peripheral regions have significantly gained employment share in four of these sectors. Accession to the EU has favoured countries’ peripheral regions in terms of manufacturing employment and their central regions in terms of service employment.     

The impact of Greek labour market regulation on temporary employment – evidence from a survey in Thessaly,Greece

This paper uses an original data-set for 186 workplaces in Thessaly (central Greece), to study consequences of Greece's strict employment protection law (EPL) and national minimum wage for temporary employment. We find higher temporary work contract rates among workplaces that pay low wages close to the minimum. We also find that EPL ‘matters’, in particular, managers who prefer temporary contracts because temporary workers are less protected definitely employ more. Our findings thus support the view that a firm's HRM decisions regarding internal versus external allocation of tasks are influenced by labour regulation.     

Effects of the ‘principle of non‐discrimination’ on temporary agency work: compensation and working conditions of temporary agency workers in 15 European countries

This article examines, with reference to Europe (EU‐15), whether temporary agency workers experience less favourable working conditions and compensation than employees with a standard employment contract. Furthermore, it analyses whether the same differences exist in European countries with and without the principle of non‐discrimination in force. The results show that discrimination of temporary workers persists even when we control for other factors. Second, in countries with the principle of non‐discrimination in force, the discrimination is higher with respect to employer‐provided training.     

Human resource strategies and contingent workers: The case of safety and health in the petrochemical industry

One of the most important economic developments in recent years is the growth in the number of temporary and contract employees. Little is known, however, about the implications these contingent employees have for human resource practices. This paper presents the results of a study of one group of contingent workers, contract workers in the petrochemical industry. The primary concern of this study is the consequences contract workers have for safety, a hotly debated and politically charged issue in an industry where safety mishaps can have catastrophic consequences. We find that contract employees offer petrochemical firms an important degree of flexibility in meeting rapid fluctuations in their demand for labor. Contract employment relationships also create stresses with potentially severe adverse effects on workplace safety. Overcoming these threats to safety while maintaining flexibility will require a high level of coordination among human resource professionals, line managers, corporate executives, unions, and government agencies.     

Support for part-time work as a channel to female employment: the moderating effects of national gender empowerment and labour market conditions

Using a multi-source data set collected across eight European countries, this article examines how characteristics of both the organizational environment and the larger national context relate to the organizational-level variable of women's employment. Our study revealed that, in countries that were high in gender empowerment measure (GEM), establishments that were more supportive of part-time work options also employed a higher proportion of women. One reason for this relationship may be that in high-GEM countries offering part-time employment is a way for an organization to signal its support for work–life balance, something that makes it more attractive to women. In countries with low GEM, an establishment's greater support for part-time work was associated with employing a greater proportion of women only when establishments experienced recruitment difficulties. Key differences in gender empowerment between countries are discussed.     

Working time flexibility across Europe: a typology using firm‐level data

Using the European Establishment Survey of Working Times, we derive a typology of firms based on the mix of flexible working time practices they employ. Six flexibility profiles are distinguished, each representing a considerable proportion of establishments. The typology not only differentiates between more and less flexible firms, but also between the focus of the practices firms adopt, stressing that flexibility is not a one‐dimensional concept. We also investigate what firm characteristics are good predictors of the adoption of a certain flexibility profile and how the profiles are related to performance and perceived HRM bottlenecks.     

University research scientists as knowledge workers: contract status and employment opportunities

University research scientists epitomise knowledge workers who are positioned to avail of the employment conditions associated with ‘boundaryless careers’. Yet while employment flexibility has been hailed as a positive feature of knowledge work, relatively little is known about the forms such flexibility may take or its impact. This article considers the factors shaping the employment conditions of 40 research scientists working in five university research centres in Ireland. The findings suggest that, for knowledge workers such as research scientists, contract employment can deny them access to many of the employment conditions and opportunities that govern their long-term success as researchers.     

Temporary jobs and job search effort in Europe

Using longitudinal data on individuals from the European Community Household Panel (ECHP) for eleven countries during 1995-2001, I investigate temporary job contract duration and job search effort. The countries are Austria, Belgium, Denmark, Finland, France, Greece, Ireland, Italy, the Netherlands, Portugal and Spain. I construct a search model for workers in temporary jobs which predicts that shorter duration raises search intensity. Calibration of the model to the ECHP data implies that at least 75% of the increase in search intensity over the life of a 2+ year temporary contract occurs in the last six months of the contract. I then estimate regression models for search effort that control for human capital, pay, local unemployment, and individual and time fixed effects. I find that workers on temporary jobs indeed search harder than those on permanent jobs. Moreover, search intensity increases as temporary job duration falls, and roughly 84% of this increase occurs on average in the shortest duration jobs. These results are robust to disaggregation by gender and by country. These empirical results are noteworthy, since it is not necessary to assume myopia or hyperbolic discounting in order to explain them, although the data clearly also do not rule out such explanations.     

Engaging workers in resource-poor environments: the case of social enterprise in Vietnam

Abstract

How do social enterprises acquire and retain employees in resource-poor environments? This paper presents findings from a study examining human resource management (HRM) practices in transitional economy social enterprises, where research on HRM remains underexplored. Drawing on social exchange theory and employing a multiple-case study design, we examine the ways in which four well-established social enterprises in Vietnam use high-involvement work practices (HIWPs) to acquire, retain and support the performance of workers. The findings suggest that HIWPs increase the social exchange value of social enterprise employment but raise questions about business sustainability. We identify evidence of a unique bundle of HIWPs, which comprise four dimensions of the original model: information, knowledge, power, and rewards, and one new dimension, namely family-building practices.     

THE IMPACT OF LABOR MARKET REGULATION ON EMPLOYMENT IN LOW‐INCOME COUNTRIES: A META‐ANALYSIS

Controversy over labor market policy often centers on achieving a balance between preventing worker exploitation, and avoiding loss of productivity or employment through excessive regulation. Although the literature documenting the impact of labor market regulation on employment is extensive, there is a dearth of evidence on the impact of such policies in low‐income countries (LICs). Since it is easier for workers, especially women, to slip into the informal sector in LICs, regulations are likely to have stronger impacts on formal employment in these countries (but lower impacts on unemployment). We systematically reviewed available research from countries that are, or were until recently, LICs. Most studies document that more stringent labor regulations are associated with lower formal sector employment and higher informal sector employment. We also conducted a metaregression analysis of the impact of minimum wages on formal and informal employment. After controlling for publication bias, higher minimum wages are associated with lower formal employment and a higher share of informal workers.     

Financial participation and recruitment and retention: causes and consequences

Using a sample of over 5000 establishments in Germany, we analyze the antecedents and effects of profit sharing (PS) and employee share ownership (ESO) with respect to the ability of firms to meet their recruitment and retention objectives and to achieve employment growth. We draw on both economic and behavioral perspectives to argue that firms that adopt PS and ESO plans do so in order to attract and retain employees. Using logistic regression and a propensity score matching technique, we find that firms that face higher recruitment problems, and those that have greater employment growth objectives, are more likely to use ESO and PS. Unlike ESO, PS enhances firm-level employment growth. However, neither ESO nor PS help firms to fully resolve recruitment and retention problems.     

Do employment subsidies work? Evidence from regionally targeted subsidies in Turkey

This paper studies the effects on registered employment and number of registered establishments of two employment subsidy schemes in Turkey. We implement a difference-in-differences methodology to construct appropriate counterfactuals for the covered provinces. Our findings suggest that both subsidy programs did lead to significant net increases in registered jobs in eligible provinces (5%–13% for the first program and 11%–15% for the second). However, the cost of the actual job creation was high because of substantial deadweight losses, particularly for the first program (47% and 78%). Because of better design features, the second subsidy program had lower, though still significant, deadweight losses (27%–46%). Although constrained by data availability, the evidence suggests that the dominant effect of subsidies was to increase social security registration of firms and workers rather than boosting total employment and economic activity. This supports the theory that in countries with weak enforcement institutions, high labor taxes on low-wage workers may lead to substantial incentives for firms and workers to operate informally.     

Excess worker turnover and fixed-term contracts: Causal evidence in a two-tier system

Portuguese firms engage in intense reallocation, most employers simultaneously hire and separate from workers, resulting in high excess worker turnover flows. These flows are constrained by the employment protection gap between open-ended and fixed-term contracts. We explore a reform that increased the employment protection of open-ended contracts and generated a quasi-experiment. The causal evidence points to an increase in the share and in the excess turnover of fixed-term contracts in treated firms. The excess turnover of open-ended contracts remained unchanged. This result is consistent with a high degree of substitution between open-ended and fixed-term contracts. At the firm level, we also show that excess turnover is quite heterogeneous and quantify its association with firm, match, and worker characteristics.     

Management Strategy and Labour Flexibility In Japanese Manufacturing Enterprises

Since the 1970s Japanese labour relations and management practices have been scrutinised as Western firms search for ways to improve their productivity and international competitiveness. Pervading this literature is the view that the Japanese labour market is flexible and adaptable. the purpose of this article is to ascertain if flexibility is a key strategic objective of management and if Japanese firms adopt a core-peripheral approach to employment. the research is based on a survey of Japanese enterprises conducted and detailed interviews with senior managers. the major finding is that Japanese labour practices have a strategic component and that the use of casual and contract workers is consistent with a core-peripheral labour strategy.     

Employment protection reforms,employment and the incidence of temporary jobs in Europe: 1996–2001

This paper uses longitudinal data on individuals from the European Community Household Panel over the 1996–2001 period to investigate the impact of reforms of employment protection systems in nine countries on the incidence of employment and of temporary jobs for wage and salary workers. Important features of the research design include the use of individual fixed effects models as well as the inclusion of country-specific trends in the dependent variable. A robust finding is that policies making it easier to create temporary jobs on average raise the likelihood that wage and salary workers will be in temporary jobs. This effect is felt primarily when the regional unemployment rate is relatively high. However, there is no evidence that such reforms raise employment. Thus, these reforms, while touted as a way of jump-starting individuals' careers in the job market, appear rather to encourage a substitution of temporary for permanent work.     

The effect of environmental innovations on employment changes: an econometric analysis

This paper examines the determinants of employment changes due to an environmental innovation of an establishment. The data stem from telephone surveys in five European countries. 1594 interviews have been realized with environmentally innovative establishments representing the European industry and service sector. Based on results of discrete choice models, we show that if the most important environmental innovation is a product or service innovation it has a significantly positive effect on the probability of an increase in employment compared with the probability of no noticeable change. In contrast, if the most important environmental innovation is an end‐of‐pipe innovation it has a significantly positive influence on employment decrease. Methodologically, we consider the multinomial logit model and several multinomial probit models. We find that the estimates of the parameters of the explanatory variables are very similar in the different approaches. Copyright © 2004 John Wiley & Sons, Ltd and ERP Environment.
