This paper aims to shed some new insights on the long‐debated and both extensively and intensively explored relationship between market concentration and industry R&D intensity. In order to do so, this study develops, from a classic Dorfman‐Steiner [1954] model of firm R&D, a model of industry R&D, where consumer preference over quality and price, R&D technology, and the joint distribution of firm‐specific technological competence and market share jointly determine the level of industry R&D intensity. The joint distribution term, which reflects both the underlying distribution of firms‐specific technological competence and the strength of its link with market share, suggests that the concentration‐R&D relationship differs depending on the strength of the link or simply the appropriability of R&D in terms of market share: A positive relationship is predicted for low‐appropriability industries, where market concentration supplements low R&D appropriability, while a negative or an inverted U‐shaped relationship for high‐appropriability industries. An empirical analysis of data, disaggregated at the five‐digit SIC level, on R&D and market concentration of Korean manufacturing industries provides supportive evidence for the predictions. 相似文献

Health is determined by an accumulative process, so a perspective on life cycle is crucial in any health prevention programme. As a consequence of this accumulative dimension, lifestyles are a key determinant of the state of health of older people. The main contribution of this paper is to explain gender differences in lifestyle and the implications of lifestyle in men's and women's states of health. We have implemented our empirical analysis into Spanish society through the use of a self‐elaborated survey. From this survey, we have drawn a subsample of 938 people older than 14 years old who live in the Spanish neighbourhood of Casablanca, Zaragoza (452 men and 486 women). We conclude that men tend to consume more substances that may negatively affect their state of health (alcoholic beverages, tobacco products and coffee), and they are also less careful in keeping an adequate weight and dental hygiene. On the other hand, women tend to be more sedentary. These results are decisive for policy makers that strive to improve the citizens’ state of health, because it is not only important to improve the quality and extension of healthy goods and services, but also to promote healthy lifestyles. 相似文献

Multilateral negotiations on agriculture in the WTO are making very little progress as developed economies are reluctant to bind trade‐distorting domestic support and import tariffs at levels acceptable to developing countries. This paper presents the basic Bagwell–Staiger framework as it relates to agricultural trade negotiations. In its basic version, market access commitments are sufficient to achieve efficient trade agreements. We show that vertical linkages between agricultural goods and processed food commodities may prevent countries to reach an efficient trade agreement. We argue that the features of agricultural supply chains hinder the argument that total discretion over domestic policies is appropriate. Les négociations multilatérales de l'OMC sur l'agriculture progressent très lentement étant donné que les pays développés hésitent à maintenir un soutien interne qui fausse les échanges et des barrières tarifaires à des niveaux acceptables pour les pays en développement. Le présent article traite du modèle Bagwell–Staiger dans le contexte des négociations sur le commerce des produits agricoles. Dans sa version de base, les engagements quant à l'accès au marché sont suffisants pour permettre des échanges commerciaux efficaces. Nous montrons que les liens verticaux entre les produits agricoles et les produits alimentaires transformés peuvent empêcher les pays d'atteindre un accord commercial efficace. Nous soutenons que les caractéristiques des chaînes d'approvisionnement agricole entravent l'argument voulant que l'entière discrétion quant aux politiques intérieures soit appropriée. 相似文献

This paper investigates a fundamental issue in the current research on strategic groups: the existence or non‐existence of the so‐called ‘stable strategic time periods’ (SSTPs). Our study provides new evidence by adding new methodological and theoretical insights. The research setting is the Spanish banking industry over a 15‐year period, 1983–1997. Unlike all prior longitudinal research that found SSTPs, the multi‐method procedure that we used in this study (i.e. equality of variance and covariance matrix and mean vector of strategic variables and a subsequent grouping analysis performed through the MCLUST) has led us to reject the existence of SSTPs in the industry under study. Based on these original findings, we conclude by suggesting a proposition which should be corroborated in future empirical studies on strategic groups. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

In the late 1980s and early 1990s, 12 states and the District of Columbia passed maternity leave legislation (MLL) allowing mothers a period of leave from work after childbirth. In 1993, President Clinton signed the first piece of federal MLL, the Family and Medical Leave Act (FMLA). Similar to state legislation, the FMLA guarantees 12 weeks of unpaid leave for eligible mothers. I evaluate the effect of MLL on the incidence of leave taking, the probability that mothers will eventually return to work at their prechildbirth jobs, and the timing of their return. The results indicate that the legislation increases the number of mothers who eventually return to their prechildbirth jobs but that MLL does not have a statistically significant effect on the incidence of leave taking. The results also indicate that MLL allows mothers to delay their return to work at their prechildbirth jobs. 相似文献

This study examines the extent of divergence versus convergence impact on the design of performance appraisal schemes across three Chinese culture-based newly industrialised countries: Hong Kong, Taiwan and Singapore. This survey research, which assessed respondents’ perceptions of their country's predominant behavioural characteristics of management practice pertinent to performance appraisals, demonstrated significant differences among the countries under study. the results suggest that, contrary to past cross-cultural cluster research, homogeneity should not automatically be assumed in guiding important management practices such as performance appraisal. 相似文献

ABSTRACT In this study, we present the concept of resourceful sensemaking as an extension of Weick's sensemaking theory. Resourceful sensemaking extends Weick's theory by carefully examining the influence of the lifeworld on organizational sensemaking practices. Lifeworld factors that affect organizational sensemaking are brought out in a dialectical method wherein a working definition of the resourceful sensemaking concept is compared with the sensemaking practices of an administrative group. We then show how this dialectical method can help develop a more robust formulation of the resourceful sensemaking concept. The paper ends by discussing the strengths and shortcomings of the concept and suggesting directions for future organizational sensemaking research. 相似文献
