Worktime Demands and Work-Family Interference: Does Worktime Control Buffer the Adverse Effects of High Demands?

This study examined whether worktime control buffered the impact of worktime demands on work–family interference (WFI), using data from 2,377 workers from various sectors of industry in The Netherlands. We distinguished among three types of worktime demands: time spent on work according to one’s contract (contractual hours), the number of hours spent on overtime work (overtime hours), and the number of hours spent on commuting (commuting hours). Regarding worktime control, a distinction was made between having control over days off and vacations (leave control) and having control over starting and finishing times (flextime). These three worktime demands were expected to have separate as well as joint effects on WFI, whereas worktime control should buffer these adverse effects of worktime demands on WFI. Stepwise regression analyses showed that working high numbers of contractual and overtime hours was indeed associated with high WFI. Further, worktime control indeed made a difference in terms of WFI: whereas leave control contributed directly to lower WFI, flextime buffered the adverse effects of long contractual workhours. Our results suggest that very long working days should be prevented, and that worktime control may be a powerful tool to help workers maintaining a good work–family balance.     

Hartz IV: die Lösung für die Probleme in der Währungsunion?

The Hartz reforms are often regarded as the therapy which turned the so called “sick man of Europe” into a global superstar. But this diagnosis was wrong. The strength of the German economy was overshadowed by the negative effects of reunification. The decline in unemployment can partly be attributed to the end of the transformation in East Germany. It also reflects the negative cyclical situation in 2005. This analysis is in line with the finding that compared e.g. with Italy and Greece, German unemployment assistance is still very generous. Thus, for the member states of the Eurozone Hartz IV is not a promising strategy. This could be different should wage moderation be cosnidered. However, if member states practice it simultaneously, this will lead to deflation. This calls for higher wage increases in Germany and a more symmetric adjustment.     

Firm growth in industrial clusters of the United Kingdom

This article examines how firm growth is influenced by the strength of the industrial cluster in which the firm is located. It presents econometric estimates of firm growth for 56 two-digit industries in the UK. In about half of these industries, there is a positive and statistically significant association between firm growth and own-sector employment. Significant associations between firm growth and other-sector employment are less common, but where these arise they are generally negative. We find that a weak rule of thumb applies in most industries: own-sector effects are positive or insignificant, while other-sector effects are negative or insignificant. Cluster effects are strongest in manufacturing, manufacturing-related, and infrastructure, but weaker in services.

ASYMPTOTICS OF IMPLIED VOLATILITY IN LOCAL VOLATILITY MODELS

Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order. We then use these option prices approximations to calculate the first‐ and second‐order deviation of the implied volatility from its leading value and obtain approximations which we numerically demonstrate to be highly accurate.     

Genre and Postemergency Contexts: The Nexus of Strategic Communications

This article explores why organizations choose to enact public relations discourse genres after an emergency situation —organizational crises, disasters, and issues—has been resolved. In the aftermath of emergency situations, we argue that organizational communicators employ discourse messages according to five governing “commitments,” which corporate officials use to shape postemergency messages the way they do. This essay, then, is not so much a retrospective analysis of what happened in selected emergency situations but, rather, is more a prospective explanation about how to use these five governing commitments when anticipating emergencies that could happen. Organizational learning and organizational renewal are addressed accordingly. In this argument we draw upon literature in linguistics, rhetorical theory, and organization studies. Examples of postemergency situations are used to bridge theory and practice to show how what was done retrospectively can be done prospectively to prepare for communication during postemergency contexts.     

An empirical analysis of national and local advertising effect on price elasticity

This paper investigates the interaction effect of advertising and price on the market share of a consumer nondurable product. We postulate a model in which local advertising is thought to primarily affect the consumers' purchase by making the demand more price sensitive, and national advertising to affect the consumers' preference, thus making the demand less price sensitive. Moreover, we hypothesize that local advertising interaction will have more immediate effect, while national advertising interaction will have longer term interaction effects. We apply these ideas empirically, and find support for our hypotheses. Thus, the interaction effect of advertising and price can be characterized by both increased and decreased price sensitivity, depending on the type of advertising. Moreover, these effects may be present simultaneously for the same product.     

The urban growth potential of second-generation migrant entrepreneurs: A sectoral study on Amsterdam

A rise in second-generation migrant entrepreneurs and an increasing focus on modern economic sectors have become new trends in migrant entrepreneurship in recent years. Although traditional sectors are still the most popular among the first-generation migrant entrepreneurs, because of the increasing pressure and their high competitiveness in traditional areas, nowadays new market niches are rapidly developing. While the first generation has more often become active in new areas such as the producer services sector which includes finance, insurance, real estate and business-related professional services, the second generation has contributed to the emergence of new areas of immigrant business activity such as the ICT sector and the creative industries.Against this background, this study focuses on the external orientations of the second-generation migrant entrepreneurs by addressing in particular the way – and the extent to which – the choice for entrepreneurship is made by higher-educated young ethnic generations. This is a new field of entrepreneurship research in many European countries. The empirical data of our study is based on in-depth personal interviews held in the first half of 2007. We employed a recently developed multivariate qualitative classification method, coined rough set analysis, in order to investigate the motivation, goals and strategies of second generation Turkish entrepreneurs in the ICT and the financial services sector in the Netherlands.The results of our study show that the second generation Turkish entrepreneurs in the Netherlands have started to be involved in new and non-traditional sectors like ICT and financial services sectors. The motivation and driving forces of the second-generation Turkish entrepreneurs are stemming from both their personal characteristics shaped by their higher educational level and their previous working experience as an employee or entrepreneur in the same sector. The demand for and a gap in the sector as well as the growing and promising structure of the sector play also an important role in pulling the second generation Turkish immigrants to become entrepreneur in these new sectors.     

Hedonic adaptation and the role of decision and experience utility in public policy

Many economists are becoming supportive of ‘soft’ paternalistic interventions that help people to avoid common decision errors without curtailing individual autonomy. To identify when such interventions could be beneficial, and to assess their success, requires a welfare criterion. However, traditional preference or choice-based criteria cannot serve this function because they assume that whatever people choose makes them better off. An alternative criterion that bases welfare on happiness rather than choice avoids this problem but has several of its own drawbacks. Most notably, people often adapt to serious chronic health conditions, and exhibit high levels of happiness, even though both those with and those without the condition agree that it is much preferable to be healthy. After reviewing different lines of research that shed light on the pros and cons of these alternative welfare criteria, we argue that no simple criterion based on either concept can surmount these problems. Instead, evaluations of welfare will inevitably have to be informed by a combination of both approaches, patched together in a fashion that depends on the specific context.
