This Brief sheds new light on three specific aspects of economic
behavior - companies offering prize promotions, individuals making
anonymous donations, and politicians creating political advertisements.
These are considered signals that firms send to consumers, donors send
to others, and politicians send to voters, respectively. The author
shows why firms, donors, and politicians employ these behaviors, and
what their social consequences are from an economic theory perspective.
This book is intended for readers who are interested in industrial
organization, the economics of giving, and political economics. Each
topic can be seen as an application of simple economic theory to an
unusual subject matter in economics. Thus, for students, this work also
offers an introduction to analytical methods in time-inconsistency and
involving asymmetric information. The problems and economic settings
behind these topics are firms' time-inconsistency in a monopoly,
asymmetric information in individual altruism, and asymmetric
information regarding types of politicians.
