"Clearly as important providers of information, the media are more likely to promote better economic performance when they are more likely to satisfy three conditions: the media are independent, provide good-quality information, and have a broad reach. That is, when they reduce the natural asymmetry of information, as Joseph Stiglitz puts it in chapter 2, between those who govern and those whom they are supposed to serve, and when they reduce information asymmetries between private agents. Such a media industry can increase the accountability of both businesses and government through monitoring and reputational penalties while also allowing consumers to make more informed decisions.
This book cites many examples that demonstrate the value of information provided by the media. Alexander Dyck and Luigi Zingales (chapter 7) discuss how the media can pressure corporate managers and directors to behave in ways that are socially acceptable, thereby avoiding actions that will result in censure and consumer boycotts. They also report that in Malaysia, a recent survey of institutional investors and equity analysts asked which factors were most important to them in considering corporate governance and the decision to invest in publicly listed corporations. Those surveyed gave more importance to the frequency and nature of public and press comments about companies than to a host of other factors considered key in the academic debate. However, the dissemination of credible information in a timely manner depends critically on how the media business is managed and regulated. The chapters in this book document evidence on media performance and regulations in countries around the world and highlight what type of public policies and economic conditions might hinder the media in supporting economic development in poor countries."
