Leopold Sögner 《Empirical Economics》2001,26(3):553-564
Okun's Law postulates an inverse relationship between movements of the unemployment rate and the real gross domestic product (GDP).
Initial empirical estimates for US data indicate that a two to three percent GDP growth rate above the natural or average
GDP growth rate causes unemployment to decrease by one percentage point and vice versa. In this investigation we check whether
this postulated relationship exhibits structural breaks by means of Markov-Chain Monte Carlo methods. We estimate a regression
model, where the parameters are allowed to switch between different states and the switching process is Markov. As a by-product
we derive an estimate of the current state within the periods considered. Using quarterly Austrian data on unemployment and
real GDP from 1977 to 1995 we infer only one state, i.e. there are no structural breaks. The estimated parameters demand for
an excess GDP growth rate of 4.16% to decrease unemployment by 1 percentage point. Since only one state is inferred, we conclude
that the Austrian economy exhibits a stable relationship between unemployment and GDP growth.

Given the growing popularity of the open innovation model, it is increasingly common to source knowledge for new product ideas from a wide range of actors located outside of organizational boundaries. Such open search strategies, however, might not always be superior to their closed counterparts. Indeed, widening the scope of knowledge sourcing at the ideation stage typically comes at a price given the substantial monetary and nonmonetary costs often incurred in the process of identifying, assimilating, and utilizing external knowledge inputs. Considering both the benefits and costs of search openness, the authors develop a project‐level contingency model of open innovation. This model suggests that search openness is curvilinearly (taking an inverted U‐shape) related to new product creativity and success. They hence assume that too little as well as too much search openness at the ideation stage will be detrimental to new product outcomes. Moreover, they argue that the effectiveness of open search strategies is contingent upon the new product development (NPD) project type (typological contingency), the NPD project leader (managerial contingency), and the NPD project environment (contextual contingency). To test these propositions empirically, multi‐informant data from 62 NPD projects initiated in the English National Health Service (NHS) were collected. The econometric analyses conducted provide considerable support for a curvilinear relationship between search openness and NPD outcomes as well as for the hypothesized contingency effects. More specifically, they reveal that explorative NPD projects have more to gain from search openness at the ideation stage than their exploitative counterparts. Moreover, the project‐level payoff from search openness tends to be greater, when the project leader has substantial prior innovation and management experience, and when the immediate work environment actively supports creative endeavors. These findings are valuable for NPD practice, as they demonstrate that effective knowledge sourcing has much to contribute to NPD success. In particular, pursuing an open search strategy might not always be the best choice. Rather, each NPD project is in need of a carefully tailored search strategy, effective leadership, and a supportive climate, if the full value of external knowledge sourcing is to be captured. 相似文献

This article introduces compliance disclosure regimes to business ethics research. Compliance disclosure is a relatively recent
regulatory technique whereby companies are obliged to disclose the extent to which they comply with codes, ‘best practice
standards’ or other extra-legal texts containing norms or prospective norms. Such ‘compliance disclosure’ obligations are
often presented as flexible regulatory alternatives to substantive, command-and-control regulation. However, based on a report
on experiences of existing compliance disclosure obligations, this article will identify major weaknesses that prevent them
from becoming effective mechanisms to discipline a certain type of behaviour. It will be argued that regulatory recourse to
compliance disclosure obligations is nonetheless worthwhile if we view them as mechanisms that can initiate a dialogue about
norm interpretation, application and norm desirability. From this perspective, compliance disclosure obligations serve less
to discipline companies by making corporate practices transparent, and more to trigger a process of norm development, in which
the law, companies and their stakeholders interact. This article provides an illustration of how mandatory disclosure, if
it is restricted to a unilateral communication process, may produce no effective results (or even prove counterproductive),
whilst highlighting the alternative potential of disclosure as an initiator of dialogue, supported by laws, geared towards
the development and refinement of norms applicable to business in a global context and the values they promote. 相似文献

Background Regularly available data has been shown to be inadequate for developing, implementing, and evaluating injury prevention and control programs in Nicaragua. A specific prevention-oriented local injury surveillance system has therefore been set up in the city of León. Objectives The aim of this paper is to describe the epidemiology of fatal and non-fatal injuries over a one-year period in a well-defined local population in Nicaragua, as emerging from the perspective of emergency room and inpatient treatments over a one-year period. Methods A hospital-based injury surveillance system was established to collect data for different levels of severity. All treated unintentional and intentional injuries were registered, including information on the external causes according to the ICD-9. Results Of all emergency room visits, 15.9% (9,970) were injuries. For every death due to injuries, there were 31 hospital admissions and 253 emergency room visits. Home and street/roads were the main arenas for the accidents. The estimated underreporting rate was about 6%, and in 20.3% of the cases, no E-code was assigned. The overall incidence and mortality rates were 56.2 per 1,000 and 20 per 100,000 inhabitants, respectively. However, comparison with a parallel household survey showed that the reporting rate of the surveillance system is only about 9%. The overall ratio of male to female injury rates was 2.1 to 1. The main causes of non-fatal injuries were falls, whereas the main cause of death was traffic accidents. Conclusions Hospital discharge and emergency room data systems are effective and feasible means for collecting the data needed to prevent injuries. However, in a country like Nicaragua with limited access to hospital health services, it is necessary to supplement such a system with additional sources of information in order to gain a more comprehensive picture of injury occurrence. 相似文献

Die Krise Griechenlands w?chst sich zu einer Gefahr für den gesamten Euroraum aus. Wie soll die Europ?ische Union darauf reagieren?
Sie befindet sich im Dilemma zwischen Bailout und Bestrafung des „Defizitsünders“. Das erste scheint für den Bestand der W?hrungsunion
unvermeidlich, das zweite ist erforderlich, um einen Moral Hazard zu vermeiden. 相似文献

We conduct a real-effort task experiment where subjects’ performance translates into a donation to a charity. In a within-subjects design we vary the visibility of the donation (no/private/public feedback). Confirming previous studies, we find that subjects’ performance increases, that is, they donate more to charity, when their relative performance is made public. In line with the competitive altruism hypothesis, a biology-based explanation for status-seeking behavior, especially male subjects increase performance in the public setting. 相似文献
