"This book synthesizes and extends recent research on the role that imperfect and dispersed information plays in macroeconomics and finance. By way of many examples and applications, Laura Veldkamp forcefully argues that research in this area should more strongly emphasize how information is produced and exchanged, and how agents choose their information. The book discusses new modeling approaches and new applications, draws many connections between different topics, and covers new techniques. While covering this new theoretical ground, Veldkamp insists on explaining stylized facts, addressing empirical puzzles, and generating testable predictions."--Pierre-Olivier Weill, University of California, Los Angeles
