A few years ago, publishing companies started to sell digital copies of their magazines. This study investigates a consequence of this change: the increasing online trade with illegal copies. We ...collected data on almost 10,000 issues of German magazines that are illegally offered online. The files are distributed in a three-sided market, in which a small number of platforms bring suppliers of illegal copies, consumers, and advertisers together. The market has been growing rapidly-between 2009 and 2012 by a factor of 10. In contrast to the legal magazine market, the illegal trade mostly concerns IT and consumer electronics magazines.

This handbooks series aims to integrate knowledge of communication structures and processes. It is global in orientation, dedicated to cultural and epistemological diversity as well as different ...scholarly approaches. The series features volumes on 'messages, codes and channels', 'mode of address: communication situations and context', 'methodology in communication science' and 'application areas'. The latter features volumes devoted to a large range of specialist areas of communication science. The series as a whole aims at meeting the needs of undergraduates, postgraduates, academics and researchers across the area of communication studies.

Book Chapter
This chapter reviews recent trends in empirical research on media and communication. In terms of data collection, researchers have been making increasing efforts to retrieve publicly available online ...data via application programming interfaces (APIs) and by using methods to crawl, scrape, and parse information. At the same time, there has been a trend to compile original datasets by digitizing material from historical sources. When it comes to measurement, the literature has benefited from automated methods that allow to analyze text as data, including text mining and natural language processing. Finally, a growing number of studies has been applying techniques that allow for causal inference with observational data. Methods such as instrumental variable regression, differences-in-differences, and regression discontinuity have become popular alternatives when controlled laboratory experiments are not feasible or desirable.
We study the effect of media coverage on individual behaviour 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 mandatory 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 behavioural 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.

In the past decade, weak household consumption was an important reason for low rates of overall economic growth in Germany. Many explanations for the weakness have been provided and investigated in ...previous studies, but the role of media-driven uncertainty has not been addressed. Therefore, this study examines the link between economic news coverage and aggregate consumption. Consumption, information-processing, and decision-making theory all serve to derive hypotheses, which are evaluated using time-series data and information obtained from media content analyses. For the period from 2001 to 2009, the results indicate that consumption is mainly influenced by the long-run effects of news coverage. In this regard, decisions to consume are subject to an optimism bias, such that favorable news leads to a stronger increase in consumption than the decrease caused by unfavorable news. Media effects are erratic in the short run though, because it takes time for households to identify new economic trends.
This study uses an original state-level data set to investigate whether press coverage on trials for tax evasion by celebrities affects the likelihood that other tax payers participate in Germany’s ...tax amnesty program. To identify the causal effect, we use exogenous variation in the reporting, resulting from disasters and terrorist attacks that coincide with the celebrity trials. Instrumental variable estimates suggest that an increase in news coverage by the amount of an average trial raises participation in the tax amnesty program by approximately 22.5%.
