Efficiency Wages,Unemployment Benefits and Union—Firm Wage Bargaining: The Issue of the Choice of the Outside Option

This paper points out that there may be a logical consistency issue in choosing the reference wage in efficiency wage models. We have shown that defining the outside option in the efficiency wage logic as the market-clearing wage solves this difficulty, and is justifiable in terms of the assumed behaviour of workers and employers. The model that we examine confirms earlier findings of reinforcing effects between union-firm bargaining and efficiency wages. However, if union preferences vary between wages and employment, Summers’ reinforcing effect is no longer present for each value of the parameter describing these preferences. Above a certain threshold value of union preferences for employment, the two mechanisms do not reinforce each other anymore.     

The Dutch and Danish Miracles Revisited: A Critical Discussion of Activation Policies in Two Small Welfare States

Denmark and the Netherlands are usually considered to belong to two different families of welfare states: the Scandinavian and the Continental model respectively. Yet, in both states active labour market policies, or activation, have increased during the 1990s and are currently prominent. Both in Denmark and in the Netherlands activation has been viewed as an important reason for the low unemployment rates which both states have experienced since the early to mid‐1990s, hence explaining the so‐called Dutch and Danish jobs miracles. The paper examines critically the activation measures taken in both countries and their alleged positive effect upon (un)employment. It further examines their effect on rights and obligations from a citizenship perspective. The paper concludes that in both cases the positive development of labour market performance cannot primarily be attributed to activation measures. Furthermore, activation has reduced the entitlements and increased the obligations affiliated with social citizenship.     

Probability Information in Risk Communication: A Review of the Research Literature

Communicating probability information about risks to the public is more difficult than might be expected. Many studies have examined this subject, so that their resulting recommendations are scattered over various publications, diverse research fields, and are about different presentation formats. An integration of empirical findings in one review would be useful therefore to describe the evidence base for communication about probability information and to present the recommendations that can be made so far. We categorized the studies in the following presentation formats: frequencies, percentages, base rates and proportions, absolute and relative risk reduction, cumulative probabilities, verbal probability information, numerical versus verbal probability information, graphs, and risk ladders. We suggest several recommendations for these formats. Based on the results of our review, we show that the effects of presentation format depend not only on the type of format, but also on the context in which the format is used. We therefore argue that the presentation format has the strongest effect when the receiver processes probability information heuristically instead of systematically. We conclude that future research and risk communication practitioners should not only concentrate on the presentation format of the probability information but also on the situation in which this message is presented, as this may predict how people process the information and how this may influence their interpretation of the risk.     

Boards of Directors in Family Businesses: A Literature Review and Research Agenda

This paper offers a review of the theoretical and empirical literature addressing boards of directors within the unique organizational setting of family businesses. By reviewing and structuring past research, this paper aims to improve the understanding of how family involvement in firms affects the roles and behaviours of boards. The review of the literature is structured according to the family business board's two primary tasks as an internal administrative body, namely the exercise of control and the provision of advice. For both board tasks, theoretical perspectives and the match between theory and empirical findings will be discussed. The review concludes by offering an integrative discussion of the relevant theories and by highlighting the need for multi‐theoretic, process and contextualized approaches in future research on boards of directors in family businesses.     

Innovation Systems and Systems Development:Lessons from History and Prospects for the Future

This paper addresses the question"What drives economic growth from a socio-technical perspective".It discusses the concept of"innovation system",especially at the national level,and its three components:actors and factors,interrelationships and dynamics.Historical examples will be given from eighteenth century England(especially the Watt-Boulton steam engine firm)and the late nineteenth and early twentieth century USA(especially the contribution of Thomas Edison).Lessons are drawn for China,focusing on Harbin Development Zone.A broader involvement of Chinese society and sustainable engineering are suggested to be conditional for further socio-economic growth.     

Romantic Relationship Commitment and Its Linkages with Commitment to Parents and Friends during Adolescence

This five‐wave longitudinal study examines linkages between adolescents' perceptions of romantic relationship commitment and the development of adolescents' perceptions of commitment to parents and friends. A total of 218 early‐to‐middle adolescents (39.0 percent boys) and 185 middle‐to‐late adolescents (30.8 percent boys) participated. Multivariate growth curves showed that higher base levels of commitment and a stronger positive development of commitment to parents and friends were associated with higher levels of later commitment to romantic partners. The effects were equally strong in early‐to‐middle adolescence and middle‐to‐late adolescence. Also, commitment to parents and commitment to friends were associated equally strong to romantic relationship commitment. No gender differences were found regarding these linkages. Overall, this study shows the importance of parents and friends for boys and girls regarding committed romantic relationships. The results support the idea of one stable and general working model used in different types of relationships.     

Marshall and Gorman's Markov chain model for occupational prestige

This report scrutinizes the Markov chain model for occupational prestige proposed by K. P. Marshall and B. L. Gorman (1975, Social Science Research 4, 41–64). It is shown that the results of their application are highly unstable.
