The Effect of Community Managers on Online Idea Crowdsourcing Activities
Lars Hornuf, Sabrina Jeworrek
Journal of the Association for Information Systems,
No. 1,
2022
Abstract
In this study, we investigate whether and to what extent community managers in online collaborative communities can stimulate community activities through their engagement. Using a novel data set of 22 large online idea crowdsourcing campaigns, we find that moderate but steady manager activities are adequate to enhance community participation. Moreover, we show that appreciation, motivation, and intellectual stimulation by community managers are positively associated with community participation but that the effectiveness of these communication strategies depends on the form of participation managers wish to encourage. Finally, the data reveal that community manager activities requiring more effort, such as media file uploads vs. simple written comments, have a stronger effect on community participation.

How Can Macroprudential Policies Transmit Within a Banking Group?
Chris Becker, Matias Ossandon Busch, Lena Tonzer
WorldBank All About Finance,
2021
Abstract
The unexpected shock represented by the COVID-19 pandemic illustrates the importance of building robust macroprudential frameworks to increase countries’ resilience against sudden disruptions in financial markets. By now, a widespread opinion among commentators and policy makers is that the macroprudential frameworks that were implemented over the past decades were effective in moderating market stress, a view supported by ample evidence on the effectiveness of macroprudential policies.

Crowdsourced Innovation: How Community Managers Affect Crowd Activities
Sabrina Jeworrek, Lars Hornuf
Abstract
In this study, we investigate whether and to what extent community managers in online collaborative communities can stimulate crowd activities through their engagement. Using a novel data set of 22 large online idea crowdsourcing campaigns, we find that active engagement of community managers positively affects crowd activities in an inverted U-shaped manner. Moreover, we evidence that intellectual stimulation by managers increases community participation, while individual consideration of users has no impact on user activities. Finally, the data reveal that community manager activities that require more effort, such as media file uploads instead of simple written comments, have a larger effect on crowd participation.

Joint Economic Forecast Spring 2018: Germany’s Economic Experts Raise Forecast Slightly
Berlin, 19 April – Germany’s leading economic experts raised their forecasts for 2018 and 2019 slightly in their Spring Joint Economic Forecast released on Thursday in Berlin. They now expect economic growth of 2.2 percent for this year and 2.0 percent for 2019, versus 2.0 percent and 1.8 percent respectively in their autumn forecast. “The German economy is still booming, but the air is getting thinner as unused capacities are shrinking“, notes Timo Wollmershaeuser, ifo Head of Economic Forecasting. Commenting on the new German government’s economic policy, he adds: “It is precisely when the government’s coffers are full that fiscal policy should reflect the implications of its actions for overall economic stability and the sustainability of public finances. The extension of statutory pension benefits outlined in the coalition agreement runs counter to the idea of sustainability.”

Comments on “Consultation BCBS discussion paper on the regulatory treatment of sovereign exposures”
Michael Koetter, Lena Tonzer
Einzelveröffentlichungen,
2018
Abstract
The BCBS discussion paper on the regulatory treatment of sovereign exposures addresses a so far hardly touched topic as concerns capital regulation. While the regulatory framework has been changed substantially over recent years including the establishment of the European Banking Union, risk weights on sovereign exposures have remained mostly unchanged and sovereign exposures of banks benefit from a favourable capital treatment. This applies despite the fact that the recent European sovereign debt crisis has revealed the potential of a doom loop between bank and sovereign risk and demonstrated that sovereign exposures are by no means “risk-free”. The paper is thus an important proposal how to change the risk evaluation of banks’ sovereign exposures.

Wirtschaft im Wandel,
No. 3,
2017
Abstract
Deutschland hat gewählt. Die Wahl hat große Verluste für die Volksparteien SPD und CDU gebracht, beide sind auf historische Tiefststände in der Wählergunst gesunken. Zusammen haben CDU und SPD nur noch knapp 54% der Stimmen; der Tag, an dem eine so genannte Große Koalition keine Mehrheit mehr haben wird, scheint nicht mehr fern. Für die CDU waren die Verluste noch deutlich dramatischer als für die SPD, was aber nicht so sehr ins Gewicht fällt, weil die CDU noch immer stärkste Partei ist und die Kanzlerin stellen kann. Allerdings kann sie nicht alleine regieren. Nachdem die SPD sich zumindest vorläufig (wenn auch nicht völlig glaubwürdig) aus der Regierungsbildung verabschiedet hat, bleibt also nur eine Jamaika-Koalition zwischen CDU, FDP und den Grünen.
