INTRODUCTION The field of behavioral economics applies psychological insights to understanding economic decision-making. Many of these insights go beyond mainstream economic models based on rationality to show how human psychological tendencies influence economic life, and may not always lead to perfectly rational choices. Further, social psychology shows how collective group dynamics and social contexts influence economic decisions. These insights have applications not only for individuals, but also for effective policy design and implementation. This module explores the applications of behavioral economics to four policy issues: 1. Economic Development: For developing countries, understanding human psychology is crucial for effective policy design. Behavioral economics can help policy-makers understand the cultural and psychological contexts of issues such as poverty, use of public goods, implementation of new programs, and so on. Policies that are mindful of psychological and social contexts can be more effective both in terms of successful adoption and in overall costs. This module will look at several cases where psychological insights can produce cost-effective policies. 2. Inequality and Discrimination by Race and Gender: Economic inequality is an issue of increasing concern to economists. Inequality exists both on the macroeconomic scale, in terms of broad income and wealth inequality, as well as in terms of race, ethnicity, gender, and other categories. Behavioral economics allows economists to better understand these forms of inequality based on how they relate to social norms, implicit bias, and psychological predispositions to inequality. Understanding how these inequalities manifest via psychology can provide important policy insights for ameliorating these social issues. 3. Finance and Economic Crises: Behavioral economics has long been relevant to the world of finance. Even from the time of John Maynard Keynes, investor and consumer psychology has been key to understanding financial markets and crises. Keynes and other pioneering economists like Hyman Minsky were early contributors to what would later become the field of behavioral finance, showing the roles of investor psychology and uncertainty in contributing to the boom and bust cycles of a capitalist economy. We will review these historical insights, and overview the modern field of behavioral finance and its applications to understanding
