German industrial production is predicted in a real-time out-of-sample forecasting experiment using more than 17,000 models formed of all possible combinations with a maximum of 3 out of 48 macroeconomic, survey, and media indicators. It is demonstrated that media data are indispensable when it comes to the prediction of German industrial production both for individual models and as a part of combined forecasts. They increase reliability by improving accuracy and reducing instability of the forecasts, particularly during the recent global financial crisis.

“…The official data then serves as the benchmark against which to check the reporting. The data has been used for consumption research (Kholodilin et al, 2010;Vosen, 2009, 2010), housing prices (Kulkarni et al, 2009), unemployment (Askitas andZimmermann, 2009;D'Amuri and Marcucci, 2010), as well as finance (Sims, 2010) and policy (Bersier, 2010). It has also been used to enhance the performance of more traditional forecasting models as in Kholodilin et al (2009).…”
Purpose -The purpose of this paper is to investigate the extent to which the authors can use internet search data in order to capture the impact of the 2008 Financial and Economic Crisis on well-being. Design/methodology/approach -The authors look at the G8 countries with a special focus on USA and Germany and investigate whether internet searches reflect the "malaise" caused by the crisis. The authors focus on searches that contain the word "symptoms" and are thought to proxy self-diagnosis and those that contain "side effects" and are thought to proxy treatment. Findings -The authors find that "malaise" searches spike in a fashion coincident with the crisis and its contagion timeline across the G8 countries. The authors show that results based on search recover previously known stylized facts from the economics of health, well-being and the business cycle. Research limitations/implications -Internet penetration is high across the G8 countries. The authors nonetheless cannot get a good handle on the part of the population, which is not online. Moreover the authors cannot get a good grip on all confounding factors. More research would be necessary with access to search microdata. Originality/value -The authors propose global proxies for diagnosis and treatment based on the "search buzz" for symptoms and side effects. The authors can thus capture trends on a global scale. This approach will become increasingly important.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
