- News media coverage on newsworthy but unrepresentative sectors can be an independent source of business cycle fluctuations, even if the information conveyed is accurate.
- Fluctuations are generated because firms across all sectors of the economy make hiring and production decisions based on the news media coverage.
- New research shows that the fall in employment and GDP observed during the recession in 2009 can largely be explained by news media covering almost exclusively the crisis-hit sectors at the expense of developments in sectors that were doing relatively well.

On any given day, news media report what they deem most important. This type of news selection can affect unemployment and economic growth. Even if the reported information is truthful, systematic reporting decisions can make companies more or less optimistic than they otherwise would be. This can then affect how many employees they hire, and how much they decide to produce.
Researchers have now developed a theoretical model that makes it possible to understand the various mechanisms and have used this model to analyse the economic variations that characterized the so-called Great Recession of 2008- 2009. During the crisis, the news media focused mainly on a few sectors that experienced difficulties such as the auto sector and financial industry. Although other industries did not experience the same difficulties at all, the reporting made companies too pessimistic, which probably exacerbated the crisis.
The model shows the role that the media can play in the economy and, thus, the importance of decision makers and others compensating for this in various ways in order to give companies a more accurate picture of the economic situation.

Less unequal when social networks lead to jobs
The question of how contacts affect job opportunities has long been a subject of debate. A new study by Marcus Eliason, Lena Hensvik, Francis Kramarz, and Oskar Nordström Skans sheds new light on the issue. The results challenge the perception that social contacts reinforce inequality in the labor market by primarily benefiting high-income individuals who have contacts in other high-paying firms. However, the study finds no evidence to support this notion. Instead, it reveals that contacts are more important for low-wage firms, which hire people from various income levels. Therefore, there are indications that job placements through contacts are actually more equal than traditional, more formal search methods, as such recruitments involve greater movement between income levels.

What do companies do when workers go on extended parental leave?
A lot of research investigates how parental leave affects parents' careers, women's and children's health, and how it is divided between the parents. However, less is known about how parental leave programs affect companies, which is an important question since increased parental leave can make it more expensive to hire women and affect companies' profits and competitiveness negatively. In a new study, researchers Arizo Karimi, Rita Ginja, and Pengpeng Xiao investigate how companies reacted after two Swedish parental leave reforms that extended the duration of paid leave.
