Social Knowledge Environments

Knowledge management represents a key issue for both information systems’ academics and practitioners, including those who have become disillusioned by actual results that fail to deliver on exaggerated promises and idealistic visions. Social software, a tremendous global success story, has prompted similarly high expectations regarding the ways in which organizations can improve their knowledge handling. But can these expectations be met, whether in academic research or the real world? This article seeks to identify current research trends and gaps, with a focus on social knowledge environments. The proposed research agenda features four focal challenges: semi-permeable organizations, social software in professional work settings, crowd knowledge, and cross-border knowledge management. Three solutions emerge as likely methods to address these challenges: design-oriented solutions, analytical solutions, and interdisciplinary dialogue.     

When Do State-Owned Firms Crowd Out Private Investment?

This paper examines the conditions under which a state-owned firm with a political agenda strategically crowds out investment by a private firm. Employing reduced-form analysis, we show that strategic crowding out occurs if (i) the private firm regards investments as strategic substitutes, and (ii) private investment is undesirable from the state-owned firm’s perspective. We discuss how our analysis applies to real-world markets and argue that it provides an explanation for the ambivalent evidence on the effect of public on private investment: State ownership is neither necessary nor sufficient for crowding out to occur.     

Surprise,Surprise. Ambient Media as Promotion Tool for Retailers

Ambient media evoke surprise with the aim of gaining the attention of consumers who are overexposed to traditional types of advertising. No study has yet considered the effects of unanticipated ambient media. To bridge this gap, the present article reports a field experiment entailing the manipulation of three types of ambient media that create different levels of surprise. The analysis combines observation data for 2,464 passersby, survey data from 305 respondents, and sales figures for 730 days. The results show that surprising ambient media draw attention, promote positive attitudes toward the ad, and stimulate word of mouth. Most importantly, ambient media increase purchase intention and sales revenue. Robustness checks ensure that the model is stable across several conditions, such as time of day or weather conditions. Follow-up studies further reveal that surprise elicits positive effects via two processes; the amplification of accompanying evaluations and the interplay of attention and incongruence resolution. The paper provides guidance for retailers wishing to design surprising ambient media that improve consumer attitudes and profitability.     

Impacts of 2003 CAP reform on land rental prices and capitalization

Based on a graphical analysis, we investigate the impacts of the Fischler Reform of the Common Agricultural Policy on land rental prices and the capitalization of single farm payments (SFP) into land values. The model shows that the degree of capitalization mainly depends on the scarcity/surplus of SFP entitlements relative to eligible hectares, the implementation model (historical versus regional) and the land supply elasticity. If there are more SFP entitlements than eligible hectares, the degree of capitalization into land values may not decline and may even increase due to the inclusion of other supports such as animal premiums in the SFP. We test this hypothesis with an empirical analysis of cross-section data on land rental prices in Bavaria for 2005. Empirical results indicate that decoupled SFP are capitalized into rental prices to a larger degree than the coupled direct payments of the time prior to the reform.     

Management Guidance Bevorzugen professionelle Kapitalmarktteilnehmer wirklich Punktprognosen?

Mit Hilfe der Management Guidance wird durch kapitalmarktorientierte Unternehmen in unterschiedlicher Form über die voraussichtliche Entwicklung wesentlicher Gesch?ftszahlen berichtet. Vorliegende empirische Arbeiten gehen einheitlich davon aus, dass eine Punktprognose der erwarteten zukünftigen Kennzahlen anderen Formen vorzuziehen ist. über die diesbezüglichen Pr?ferenzen professioneller Kapitalmarktteilnehmer liegen bisher jedoch kaum gesicherte Erkenntnisse vor. Der vorliegende Beitrag untersucht daher auf Basis einer Fragebogenstudie die entsprechenden Pr?ferenzen dieser wichtigen Zielgruppe. An der Befragung nahmen insgesamt 123 Kapitalmarktteilnehmer teil, insb. Sell- und Buy-Side-Analysten sowie Asset Manager. Entgegen den bisherigen Annahmen wird eine Intervallprognose als hilfreicher angesehen als eine Punktsch?tzung. Weitergehende Analysen erlauben Einblicke in die Pr?ferenzen einzelner Berufsgruppen.     

Die Auswirkungen der steigenden Lebenserwartung auf die Prävalenz der Pflegebedürftigkeit in Deutschland

As a consequence of population ageing the number of persons in need of care will rise considerably in the decades to come. While the rise per se is uncontroversial a still open question is whether the increase in longevity will raise or lower the age-specific prevalence of long term care. As there are both empirical studies finding an increase or a decrease of prevalence as life expectancy increases, most existing projections of the number of persons in need of care are based on the assumption of constant age-specific prevalence rates. While this question cannot be answered ultimately from the current point of view, this paper gives some guidance on the range of the future increase in cases. To this end we first analyze the interplay of changes in mortality, incidence and prevalence within a flow figure model. This approach allows for a better understanding of the conditions which must be met for an increase or a decline of the prevalence of care in the future. Based on German data we then adapt a scenario approach to analyze the model's quantitative implications for the prevalence of care and the number of nursing cases in the future. Our results indicate that the number of nursing cases will range between 2,6?m and 7?m persons in the year 2060. Nonetheless, based on the existing empirical findings for Germany and other industrialized countries, a doubling on 4?m persons in need of care seems to be the most realistic scenario.     

Functional income distribution and aggregate demand in the Euro area

An increase in the wage share has contradictory effects on thesubaggregates of aggregate demand. Private consumption expendituresought to increase because wage incomes typically are associatedwith higher consumption propensities than capital incomes. Investmentexpenditures ought to be negatively affected because investmentwill positively depend on profits. Net exports will be negativelyaffected because an increase in the wage share corresponds toan increase in unit labour costs and thus a loss in competitiveness.Therefore, theoretically, aggregate demand can be either wage-ledor profit-led depending on how these effects add up. The resultswill crucially depend on how open the economy is internationally.The paper estimates a post-Kaleckian macro model incorporatingthese effects for the Euro area and finds that the Euro areais presently in a wage-led demand regime. Implications for wagepolicies are discussed.
