Book Description
Does fake news in financial markets attract more investor attention and have a significant impact on stock prices? We use the SEC crackdown of stock promotion schemes in April 2017 to examine investor attention and the stock price reaction to fake news articles. Using data from Seeking Alpha, we find that fake news stories generate significantly more attention than a control sample of legitimate articles. We find no evidence that article commenters can detect fake news and Seeking Alpha editors have only modest ability to detect fake news. However, we show that machine learning algorithms can successfully identify fake news from linguistic features of the article. The stock market appears to price fake news correctly. While abnormal trading volume increases around the release of fake news, the increase is less than that observed for legitimate news. The stock price reaction to fake news is discounted when compared to legitimate news articles.

Book Description
Prior research documents capital market benefits of increased investor attention to accounting disclosures and media coverage, however little is known about how investors and markets respond to attention-grabbing events that reveal little nonpublic information. We use daily firm advertising data to test how advertisements, which are designed to attract consumers' attention, influence investors' attention and financial markets (i.e., spillover effects). Exploiting the fact that firms often advertise at weekly intervals, we use an instrumental variables approach to provide evidence that print ads, especially in business publications, trigger temporary spikes in investor attention. We further find that trading volume and quoted dollar depths increase on days with ads in a business publication. We contribute to research on how management choices influence firms' information environments, determinants and consequences of investor attention, and consequences of advertising for financial markets.

Book Description
This book provides a review of current research in fake news and presents six new empirical research studies examining its impact. Fake news has garnered immense public attention following the 2016 Brexit referendum, three US elections, the 2019 Indian lynchings, and so on. Fake news undermines public life across the globe, especially in countries where journalistic practices and institutions are weak. Some fake news is created to spread ideological messages or to create mischief, whereas other fake news is created for profit. Research shows that fake news spreads farther, faster, and more broadly than true news and has had major societal impacts. All signs indicate that it will get worse as political activists, scammers, alternative news media, and hostile governments become more sophisticated in their production and targeting of fake news. This book features leading scholars who provide a review of the current research and presents six new empirical research studies examining its impact. Some of this research shows how inventions designed to reduce fake news can actually have the opposite effect, and instead act to increase the spread of fake news. Other research takes a longer-term perspective, by measuring or inserting emotions into headlines, allowing us to examine some of the roots of fake news behaviors for future study. This shows how challenging the fake news phenomenon is to solve. Fake News on the Internet will be a key resource for academics, researchers, and advanced students of Media Studies, Research Methods, Information Systems, Communication Studies, Management, Cultural Studies and Sociology. The chapters included in this book were originally published as a special issue of Journal of Management Information Systems.

Book Description
A landmark insider’s tour of how social media affects our decision-making and shapes our world in ways both useful and dangerous, with critical insights into the social media trends of the 2020 election and beyond “The book might be described as prophetic. . . . At least two of Aral’s three predictions have come to fruition.”—New York NAMED ONE OF THE BEST BOOKS OF THE YEAR BY WIRED • LONGLISTED FOR THE PORCHLIGHT BUSINESS BOOK AWARD Social media connected the world—and gave rise to fake news and increasing polarization. It is paramount, MIT professor Sinan Aral says, that we recognize the outsize effect social media has on us—on our politics, our economy, and even our personal health—in order to steer today’s social technology toward its great promise while avoiding the ways it can pull us apart. Drawing on decades of his own research and business experience, Aral goes under the hood of the most powerful social networks to tackle the critical question of just how much social media actually shapes our choices, for better or worse. He shows how the tech behind social media offers the same set of behavior influencing levers to everyone who hopes to change the way we think and act—from Russian hackers to brand marketers—which is why its consequences affect everything from elections to business, dating to health. Along the way, he covers a wide array of topics, including how network effects fuel Twitter’s and Facebook’s massive growth, the neuroscience of how social media affects our brains, the real consequences of fake news, the power of social ratings, and the impact of social media on our kids. In mapping out strategies for being more thoughtful consumers of social media, The Hype Machine offers the definitive guide to understanding and harnessing for good the technology that has redefined our world overnight.

Book Description
Although a number of selected African countries have made efforts to implement various financial sector reforms, many countries have not fully implemented the requisite reforms required for sustainable development. Instead, they have focused mainly on bank-based financial reforms, thereby neglecting market-based financial reforms. This study provides a one-stop shop for understanding the history and evolution of the financial sector in Africa with a special focus on the sub-Saharan region where the financial system in many countries is still at a relatively nascent stage. The analysis is extensive and robust, and starts from financial repression to financial liberalisation (both internal and external), and its role in sustainable development and poverty alleviation. The book covers a range of important research issues pertaining to financial development in selectede African countries, including interest rate and exchange rate reforms, the dynamics of bank-based and market-based financial development; the role of the informal financial sector in sustainable development; the finance-growth nexus; bank-based versus market-based financial sectors in Africa; financial development and information and communication technology; and financial development and gender equality, among other topics. The book also considers the relationship between the COVID-19 global pandemic and financial development, and concludes by presenting a forecast of the future trends of financial and sustainable development on the African continent in general and sub-Saharfan Africa in particular. The chapters are authored by prominent scholars and researchers in the field of finance and banking, applied econometrics and development economics, with a deep understanding and knowledge of financial development and the local situations in African countries. This book provides crucial reference material for academics, researchers, policymakers and students of all levels and is a must-read for anyone wishing to understand the nature of finance and sustainable development in Africa in relation to the rest of the world. It covers African countries, but with more emphasis on the sub-Saharan African region where the financial systems in many of the countries are still relatively underdeveloped.

Book Description
Inflation is regarded by the many as a menace that damages business and can only make life worse for households. Keeping it low depends critically on ensuring that firms and workers expect it to be low. So expectations of inflation are a key influence on national economic welfare. This collection pulls together a galaxy of world experts (including Roy Batchelor, Richard Curtin and Staffan Linden) on inflation expectations to debate different aspects of the issues involved. The main focus of the volume is on likely inflation developments. A number of factors have led practitioners and academic observers of monetary policy to place increasing emphasis recently on inflation expectations. One is the spread of inflation targeting, invented in New Zealand over 15 years ago, but now encompassing many important economies including Brazil, Canada, Israel and Great Britain. Even more significantly, the European Central Bank, the Bank of Japan and the United States Federal Bank are the leading members of another group of monetary institutions all considering or implementing moves in the same direction. A second is the large reduction in actual inflation that has been observed in most countries over the past decade or so. These considerations underscore the critical – and largely underrecognized - importance of inflation expectations. They emphasize the importance of the issues, and the great need for a volume that offers a clear, systematic treatment of them. This book, under the steely editorship of Peter Sinclair, should prove very important for policy makers and monetary economists alike.

Book Description
The Financial Crisis Inquiry Report, published by the U.S. Government and the Financial Crisis Inquiry Commission in early 2011, is the official government report on the United States financial collapse and the review of major financial institutions that bankrupted and failed, or would have without help from the government. The commission and the report were implemented after Congress passed an act in 2009 to review and prevent fraudulent activity. The report details, among other things, the periods before, during, and after the crisis, what led up to it, and analyses of subprime mortgage lending, credit expansion and banking policies, the collapse of companies like Fannie Mae and Freddie Mac, and the federal bailouts of Lehman and AIG. It also discusses the aftermath of the fallout and our current state. This report should be of interest to anyone concerned about the financial situation in the U.S. and around the world.THE FINANCIAL CRISIS INQUIRY COMMISSION is an independent, bi-partisan, government-appointed panel of 10 people that was created to "examine the causes, domestic and global, of the current financial and economic crisis in the United States." It was established as part of the Fraud Enforcement and Recovery Act of 2009. The commission consisted of private citizens with expertise in economics and finance, banking, housing, market regulation, and consumer protection. They examined and reported on "the collapse of major financial institutions that failed or would have failed if not for exceptional assistance from the government."News Dissector DANNY SCHECHTER is a journalist, blogger and filmmaker. He has been reporting on economic crises since the 1980's when he was with ABC News. His film In Debt We Trust warned of the economic meltdown in 2006. He has since written three books on the subject including Plunder: Investigating Our Economic Calamity (Cosimo Books, 2008), and The Crime Of Our Time: Why Wall Street Is Not Too Big to Jail (Disinfo Books, 2011), a companion to his latest film Plunder The Crime Of Our Time.
