The Effect of Community Managers on Online Idea Crowdsourcing Activities
Journal of the Association for Information Systems,
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.
Explaining Regional Disparities in Housing Prices Across German Districts
IWH Discussion Papers,
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: Growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: Increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
Does Working at a Start-up Pay Off?
Small Business Economics,
Using representative linked employer-employee data for Germany, this paper analyzes short- and long-run differences in labor market performance of workers joining start-ups instead of incumbent firms. Applying entropy balancing and following individuals over ten years, we find huge and long-lasting drawbacks from entering a start-up in terms of wages, yearly income, and (un)employment. These disadvantages hold for all groups of workers and types of start-ups analyzed. Although our analysis of different subsequent career paths highlights important heterogeneities, it does not reveal any strategy through which workers joining start-ups can catch up with the income of similar workers entering incumbent firms.
The Real Effects of Universal Banking: Does Access to the Public Debt Market Matter?
Journal of Financial Services Research,
I analyze the impact of the formation of universal banks on corporate investment by looking at the gradual dismantling of the Glass-Steagall Act’s separation between commercial and investment banking. Using a sample of US firms and their relationship banks, I show that firms curtail debt issuance and investment after positive shocks to the underwriting capacity of their main bank. This result is driven by unrated firms and is strongest immediately after a shock. These findings suggest that universal banks may pay more attention to large firms providing more underwriting opportunities while exacerbating financial constraints of opaque firms, in line with a shift to a banking model based on transactional lending.

Finance-Growth Nexus and Banking Efficiency: The Impact of Microfinance Institutions
Journal of Economics and Business,
This paper investigates the relative importance of microfinance institutions (MFIs) at both the macro (financial development, economic growth, income inequality, and poverty) and micro levels (efficiency of traditional commercial banks). We observe a significant impact on most of the fronts. MFIs’ participation increases overall savings (total bank deposits) and credit allocation (loans to private sector) in the economy. Their involvement enhances economic welfare by reducing income inequality and poverty. Additionally, their active presence helps to discipline the traditional commercial banks by subjecting them to more competition triggering higher efficiency.
Competition, Cost Structure, and Labour Leverage: Evidence from the U.S. Airline Industry
IWH Discussion Papers,
I study the effect of increasing competition on financial performance through labour leverage. To capture competition, I exploit variation in product market contestability in the U.S. airline industry. First, I find that increasing competitive pressure leads to increasing labour leverage, proxied by labour share. This explains the decrease in operating profitability through labour rigidities. Second, by exploiting variation in human capital specificity, I show that contestability of product markets induces labour market contestability. Whereas affected firms might experience more stress through higher wages or loss of skilled human capital, more mobile employee groups benefit from competitions through higher labour shares.
