Econometrics and decision making: Effects of communication of results

Abstract

This thesis incorporates three studies that analyze how information is presented in various contexts, how these different modes of presentation affect decision makers’ perceptions and how to improve communication of information to eliminate distortions. Chapter 1 features a scenario where experts make inferences given different presentations of a regression analysis, a widely used statistical method. Chapter 2 introduces an experience-based presentation mode and tests its effectiveness on decision makers with varying statistical abilities, across multiple probabilistic tasks. Chapter 3 demonstrates the effects of presentation mode and the number of available options on the amounts and distributions of donations to NGOs and their campaigns. Overall, the findings suggest that presentation mode is an important determinant of judgments and decisions, and they can be restructured to improve the accuracy of inferences.
