Trade margins and exchange rate regimes: new evidence from a panel VAR

This paper studies how trade margins respond to output and terms of trade shocks in different exchange rate regimes within a panel of 23 OECD economies over the period 1988-2011. Using a panel VAR model, we confirm the predictions of entry models about the behaviour of export margins over the cycle. In addition, we find remarkable differences depending on the exchange rate regime. We document that fixed exchange rates have a positive effect on the extensive margin of trade in response to external shocks while flexible exchange rates have a pro-trade effect in response to output shocks. Our results imply that as long as extensive margins are a relevant portion of trade and external shocks are a major source of business cycle variability, the stabilization advantage of flexible exchange rates may be lower than previously thought

Misinformation, disinformation, and fake news: lessons from an interdisciplinary, systematic literature review

Even though misinformation, disinformation, and fake news are not new phenomena, they have received renewed interest since political events such as Brexit and the 2016 U.S. Presidential elections. The resulting sharp increase in scholarly publications bears the risk of lack of overview, fragmentation across disciplines, and ultimately a lack of research cumulativity. To counteract these risks, we have performed a systematic research review of 1261 journal articles published between 2010 and 2021. Results show the field is mostly data-driven, frequently investigating the prevalence, dissemination, detection or characteristics of misinformation, disinformation, and fake news. There further are clear foci concerning contributing disciplines, methodologies, and data usage. Building on our results, we identify several research gaps and suggest avenues for future research.</p

What Does Fake Look Like? A Review of the Literature on Intentional Deception in the News and on Social Media

This paper focuses on the content features of intentional deceptive information in the news (i.e., fake news) and on social media. Based on an extensive review of relevant literature (i.e., political journalism and communication, computational linguistics), we take stock of existing knowledge and present an overview of the structural characteristics that are indicative of intentionally deceptive information. We discuss the strength of underlying empirical evidence and identify underdeveloped areas of research. With this paper, we aim to contribute to the systematic study of intentional deception in the news and on social media and to help setting up new lines of research in which intentionally deceptive news items can be operationalized in consistent ways
