    In this paper we use data from industrial plants to investigate if seniority-based pay is used asa motivational device for production workers. Alternatively, seniority-based pay could simplybe a wage setting rule not necessarily related to the provision of incentives. Unlike previouspapers, we use a direct measure of seniority-based pay as well as measures of monitoringdevices and piece-rates. We find that firms that offer seniority-based pay are less likely tooffer explicit incentives. They are also less likely to invest in monitoring devices. We alsofind that firms that offer seniority-based pay are more likely to engage in other humanresource management policies that result in long employment relationships. Overall theseresults suggest that seniority-based pay is indeed used as a motivation device.Human resource management practices, incentives, monitoring

    El sobreconsumo y el infraconsumo de televisión en España

    Get PDF
    La televisió continua sent una de les activitats a les que major quantitat de temps dediquem diàriament. No obstant això, de vegades se li dedica menys temps del que es voldria (infraconsum), mentre que en altres succeeix el contrari (sobreconsum). En aquest context l'objectiu d'aquest treball ha estat analitzar quines són les característiques sociodemogràfiques dels televidents i els comportaments cap a la televisió que es troben associades a una major presència del sobreconsum i el infraconsum televisiu. Per a això s'ha examinat informació estadística sobre una mostra de 1000 teleespectadors espanyols. Els nostres resultats indiquen que tant el sobreconsum com el infraconsum de televisió estan més presents entre les dones que entre els homes, així com que els teleespectadors d'entre 65 i 74 anys d'edat són els que millor ajusten la quantitat que consumeixen de televisió als seus desitjos. El sobreconsum està més associat a veure diversos programes simultàniament i continuar veient la televisió encara que el contingut no sigui del seu gust, mentre que el infraconsum està relacionat amb encendre la televisió sense saber què s'emet. Els resultats obtinguts posen de rellevància la necessitat de tenir en compte la quantitat i no només la qualitat en els estudis sobre consum televisiu. També mostren que el infraconsum i el sobreconsum televisiu són fenòmens complexos que exigeixen la utilització de perspectives d'anàlisi multidisciplinar.Television viewing is one of the activities to which we devote a significant amount of time every day. At times, however, people may watch less TV than they would like (underconsumption), while at other times, the opposite is the case (overconsumption). In this context, the aim of this study was to analyze the sociodemographic characteristics of viewers and explore television behaviors associated with a greater incidence of television overconsumption and underconsumption. The statistical information is drawn from a sample of 1,000 Spanish viewers. Our results indicate that both overconsumption and underconsumption are more prevalent among women than among men, and that viewers between 65 and 74 years old are those whose television consumption best matches their personal wishes. Overconsumption is more closely linked with watching several TV programs at the same time, and continuing to watch television even though the content does not appeal to the viewer. Underconsumption is related to switching on the TV set without knowing what is on. The results obtained show the need to take into account quantity, not only quality, in studies of television viewing. They also show that television underconsumption and overconsumption are complex phenomena that require inquiry from a multidisciplinary range of analytical perspectives.La televisión continúa siendo una de las actividades a las que mayor cantidad de tiempo dedicamos diariamente.

Nuestros resultados indican que tanto el sobreconsumo como el infraconsumo de televisión están más presentes entre las mujeres que entre los hombres, así como que los telespectadores de entre 65 y 74 años de edad son los que mejor ajustan la cantidad que consumen de televisión a sus deseos. El sobreconsumo está más asociado a ver varios programas simultáneamente y continuar viendo la televisión aunque el contenido no sea del agrado, mientras que el infraconsumo lo está a encender la televisión sin saber qué se emite. Los resultados obtenidos ponen de relevancia la necesidad de tener en cuenta la cantidad y no solamente la calidad en los estudios sobre consumo televisivo. También muestran que el infraconsumo y el sobreconsumo televisivo son fenómenos complejos que exigen la utilización de perspectivas de análisis multidisciplinar

    A firm-level analysis of differences between adopters and non-adopters of ICT

    Get PDF
    Information and Communication Technologies investments have drastically modified the competitive markets due to the impact on firm performance and productivity. This paper aims to analyse the differences between ICT adopter firms and non-adopter firms. OLS regressions and ordered logit models provide the methodological approach. From data based on a questionnaire survey to 327 Spanish firms in 2002, the empirical results indicate the essential role played by some variables in the ICT adoption. The results confirm, for example, the influence of variables such as firm size. The role of human capital and competitive strategies based on product and service quality are relevant in ICT adoption. The paper is organised as follows. First, the section 1 introduces the paper. The section 2 provides the establishment and explanation of the theoretical hypotheses. This section is followed in the section 3 by the methodology adopted in this study, including both the model and the data sources employed in the estimations. Some basic statistics and the results of the model estimations are presented and interpreted in the penultimate section, before concluding the paper with some remarks on the findings and important implications in the ICT adoption

    The Process of Wage Adjustment: An Analysis Using Establishment-Level Data

    Get PDF
    This article presents a study of the influences on the factors that shape wage adjustments. The cost of living, comparability with other firms' wages, the fulfilment of collective agreements at sector level, the need to recruit and retain employees, the performance of the organisation, and the climate of industrial relations are included as factors of interest. The analysis was carried out using a sample of Spanish manufacturing plants. Our results show that the structural characteristics of the establishment such as its size or foreign ownership, as well as the wage setting arrangements and trade unions, play a role in explaining the importance of the factors mentioned in shaping wage adjustments. The human resource management policies adopted by the employer seem to be less relevant, although the qualification of workers and the use of pay for performance have a significant impact on the process of wage adjustment.pay settlements, collective bargaining, wage negotiation

    The Diffusion of Pay for Performance across Occupations

    In this paper the differences in the incidence of pay for performance plans between occupations in a sample of Spanish manufacturing establishments are analyzed. Our results show that there are significant differences between occupations in the incidence of individual, group and firm or plant pay for performance plans. The roles of establishment size, multinational ownership and the human resources management department in the incidence of pay for performance plans and their variability of use across occupations within the same firm are also studied. These factors are found to correlate to a greater use of pay for performance and, in most cases, this effect is homogenous across occupations.incentives

    What Are the Factors Behind Pay Settlements? Evidence from Spanish and British Data

    Get PDF
    This article presents a study of the determinants of pay settlements in a sample of Spanish and British establishments. We find that variables such as establishment size and age, foreign ownership, labour costs, the existence of internal labour markets, a strategic approach to human resource management and pay setting institutions are related to the factors that shape pay adjustments. Moreover, our findings show that there are significant differences in the determinants of pay settlements between Spain and Great Britain. We suggest that the labour market institutions developed in each country influence pay setting decisions.compensation systems, labor market institutions, wage settlements, establishment level data

    Performance Appraisal: Dimensions and Determinants

    The determinants of the dimensions that shape a formal system of performance appraisal are studied in relation to a sample of Spanish manufacturing establishments. In particular, the factors that influence the measures used to evaluate performance, the person who carries out such appraisal and its frequency are analysed. Our results show that the characteristics of the establishment exert a significant influence on the configuration of performance appraisal. Specifically, we find that the use of practices complementary to performance evaluation and the structural factors of the establishment are found to correlate closely with the dimensions of formal performance appraisal.performance appraisal, monitoring, establishment characteristics, dimensions of appraisal

    "Make-or-buy" of peripheral services in manufacturing: Evidence from Spanish plant-level data

    Full text link
    In this paper we empirically explore the make-or-buy decisions of peripheral services in manufacturing plants using detailed information on a data set from a new plant-level survey from 926 plants distributed in all manufacturing industries in Spain. In particular, survey respondents are asked how their contracting practices of peripheral services had changed in the last three years. The answer to this question is informative of the changes in the importance of backward integration for each of the plants interviewed. Using other information provided in the survey, we relate reported changes in backward integration to changes in other relevant plant characteristics. We show that increases in outsourcing of services are positively correlated with increases in the plant's market share as well as increases in product market competition and product prices. These findings are robust to controlling for whether plants belong to single-plant or multi-plant firms. This result is consistent with the view that market size limits the degree of specialization at the plant level in the Spanish manufacturing industry

    Identifying a guiding list of high involvement practices in human resource management

    Full text link
    [EN] In today global competitiveness, it is becoming increasingly frequent, the introduction of new management practices to organizations, seeking to enhance performance as a form of Management Innovation (MI). This is so because such practices are usually difficult to replicate exactly from one company to another, provided they are well rooted in the daily work in the organization. The main purpose of this paper is, by reviewing the previous work done in this area, to present a general list of Human Resource Practices (HRM practices) geared towards improving organizational effectiveness and hence better performance outcomes. Many work has been done to date within this topic, but it is difficult to find a consensus about the best way to address to this practices, and this fact makes difficult to compare different studies and their results. We present a detailed but synthesized list of those HR practices to be used as a starting point in any sector whether industrial or servicesPerelló Marín, MR.; Ribes Giner, G. (2014).
