News organizations have been under financial pressure to streamline their activities for decades. Critics argue that this pressure undermines the quality of news, posing a severe threat to democracy. However, the effects of media consolidation on news quality are theoretically ambiguous and empirical evidence is scarce. To address this gap, we study the case of the Swedish newspaper industry between 2014 and 2022, a period where more than half of the country’s newspapers changed their owners. We collect over 2 million articles from 108 newspapers and apply state-of-the-art computational methods to create theoretically grounded, fine-grained measures of news content quality. Our results indicate that mergers are associated with slight increases in content quality. However, we also find evidence of content homogenization, as merging newspapers tend to slightly decrease their provision of local news, while relying more on content shared with co-owned newspapers.

Entrepreneurs can benefit from the communities they build. Therefore, many entrepreneurs create online communities that allow self-selected stakeholders, such as customers, crowd investors, or enthusiasts, to interact with the venture and other like-minded individuals. However, research on how entrepreneurs can successfully engage community members and grow such online communities is only slowly emerging. In particular, it is unclear if, how much, and which content entrepreneurs should contribute to foster engagement in different types of communities and which role these community types play in the community's overall growth. Based on a longitudinal case study in the video game industry, we first theorize and show that-depending on the community type-both too much and too little entrepreneur-provided content fails to leverage community engagement potential and that different communities require more or less diverging content. We then theorize and show that community growth is largely driven by engagement in open communities, such as those hosted on social media. We outline the implications this has for entrepreneurs, our understanding of online communities, and entrepreneurial communities more generally. How can entrepreneurs engage and grow different types of online communities?Managing online communities is crucial for many entrepreneurs. However, different community types, open and core, play different roles and require different content and growth strategies. Core communities, such as those hosted on online forums, respond well to less but more diverse content, whereas open communities on social media drive overall community growth with more but less diverse content. Entrepreneurs need to find the right balance and pay attention to the tipping point of content provision, as too much content might endanger community member engagement. By understanding the dynamics of online communities, entrepreneurs can effectively nurture engagement and optimize their efforts for long-term success. Investing resources wisely in content production, considering the costs involved, can be beneficial for new ventures seeking sustainable community growth.

International courts lack traditional enforcement mechanisms. Scholars theorize that compliance with human rights rulings is therefore often driven by domestic processes, including political mobilization and parliamentary agenda setting. A necessary condition underlying these processes is attention to the rulings which is in part expected to be mediated by media attention. However, these conditions have not been explicitly addressed by the existing compliance literature. In this paper, we assess the impact of media attention to rulings by the European Court of the Human Rights on the likelihood of their implementation, using a novel dataset of case-specific news coverage. Exploiting exogenous variation in media attention caused by competing newsworthy events, we find that the probability of compliance increases, the more coverage a ruling receives. Our findings indicate that domestic news media play a key role for compliance with international courts.

We study the effect of media coverage on individual behavior during a public health crisis. For this purpose, we collect a unique dataset of 200,000 newspaper articles about the Covid-19 pandemic from Sweden-one of the few countries that did not impose lockdowns or curfews. We show that mentions of Covid-19 significantly lowered the number of visits to workplaces and retail and recreation areas, while increasing the duration of stays in residential locations. Using two different identification strategies, we show that these effects are causal. The impacts are largest when Covid-19 news stories are more locally relevant, more visible and more factual. We find larger behavioral effects for articles that reference crisis managers (as opposed to medical experts) and contain explicit public health advice. These results have wider implications for the design of public communications and the value of the local media.

The implications of rising parliamentary representation of populist parties have been thoroughly studied but little is known about the impact of populist state leaders on party positions. In this article, we study mainstream parties' strategic responses when a populist takes over as the leader of a nation. We use content-analytical data and large language modelling to measure positions expressed in manifestos from parties from 51 democracies between 1989 and 2018. Employing methods for causal inference from observational data, we find that right-wing populist state leaders induce mainstream parties to differentiate their positions on multiculturalism, possibly leading to polarization of the party system. Under left-wing populist leaders, mainstream parties adopt more homogenous or differentiated positions, depending on the policy category and other contextual factors. Parties are generally more responsive in emerging than advanced countries and in presidential than parliamentary systems.

The assumption that ownership has an effect on the diversity of news is based on the forms of control that ownership allows and the market conditions in which ownership is exercised. In this study, we perform a large-scale analysis of the Swedish newspaper market, surveying 130 newspapers and parliamentary speeches over a period of six years (2014-2019), to substantiate to what extent market and for-profit ownership forms impact political viewpoint diversity. Our analysis shows that newspapers with market leadership and chain ownership offer more political viewpoint diversity than number two and single-owned papers. In contrast, the ownership forms surveyed here (private, foundation, and publicly traded ownerships) display little effect on newspapers' internal diversity. We also find that a greater number of papers in a local market does not imply more external diversity in that market. The analysis thus offers some nuance to the notion that ownership form and market pluralism are prerequisites for viewpoint diversity, highlighting instead the importance of scale effects for pluralistic media systems.

Researchers often employ signaling theory to explain the effect of entrepreneurial communication on fundraising success. This focus on signaling can lead researchers to overlook alternative explanations for why communication affects fundraising, resulting in incorrect conclusions. An empirical test of whether a signaling mechanism is a good explanation for an observed relationship would help remedy such problems. We illustrate this idea by reexamining a relationship that has frequently been attributed to signaling, namely, the positive effect that updates in crowdfunding have on fundraising success. We find no support for a signaling mechanism based on a dataset of 5,908 campaign-day observations nested in 175 Kickstarter campaigns. Instead, an alternative explanation, indicating that updates provide affective stimuli, fits the data better. We provide guidance for empirical substantiations of signaling mechanisms in entrepreneurial fundraising with implications for the discussion on the boundaries of signaling theory.

Facebook has been criticized for exposing its users to low-quality and harmful information, including fake news, hate speech, and politically one-sided content. In December 2013 and again in August 2014, the platform updated its news feed algorithm to increase user exposure to quality content of news publishers, while curbing the proliferation of non-informative posts. This paper uses a sample of German newspapers to investigate the conjecture that these modifications raised the incentives to publish quality news stories on the platform, focusing on the number and diversity of news story posts about substantive political issues. Using the newspapers’ print editions as a counterfactual, our results indicate an increase in the amount of substantive political news on Facebook by approximately 30%. This expansion occurred in a politically balanced way, except that the outlets disproportionately increased their Facebook coverage of the formerly underrepresented Linke (Left Party). Consequently, the within-outlet concentration of political viewpoints decreased by about one half of the standard deviation of our concentration indices.

Algorithmic curation of social media platforms is considered to create a clickbait media environment. Although clickbait practices can be risky especially for legacy news outlets, clickbait is widely applied. We conceptualize clickbait content supply as a revision game with an unknown threshold. Combining supervised machine learning with time series analysis of Facebook posts and Twitter messages of 37 German legacy news outlets over 54 months, we observe outlets’ behavior following algorithm changes. Results reveal (1) an infrequent use of clickbait with few heavier-using outlets and (2) turning points of clickbait performance as clickbait supply and user interaction form a reversed U-shaped relationship. News outlets (3) collectively adjust toward an industry clickbait standard. While we (4) cannot prove that algorithmic curation increases clickbait, (5) Facebook’s regulative intervention to decrease clickbait disperses heterogeneous tendencies in clickbait supply. We contribute to an understanding of editorial decision-making in competitive environments facing platforms’ regulative intervention.

Airbnb and other home-sharing platforms have been facing increasing regulation over the past years, mainly in the form of restricting short-term rentals through day caps. In contrast, as one of the first countries in the world, Denmark applied a collaborative strategy: In 2018, the government negotiated an agreement with Airbnb about the transmission of income data from the platform to the tax agency. We analyze how this data-sharing agreement affected hosts' behavior on the platform, using a difference-in-differences approach with Sweden as a counterfactual. We find that the agreement reduced hosts’ propensity to list property on the platform by 14%, while increasing listing prices by 11%. Our results indicate that platform exits were mostly limited to single-property hosts. In contrast, hosts with many properties and those in areas with initially low Airbnb penetration made their rental objects more often available and managed to increase the number of bookings. Overall, the findings imply that the data-sharing agreement not only helped to increase tax compliance but also led to a commercialization and spatial re-organization of short-term renting in Denmark.
