On the role of information in strategic and individual decision making

This dissertation comprises four independent chapters, each exploring the impact of information on decision-making processes within economic contexts. The overarching theme across these chapters is the role of information in shaping human behaviour and economic outcomes. The first two chapters investigate strategic interactions involving a sender possessing information desired by a receiver. The first chapter employs game theory to analyse these interactions, while the second chapter adopts an experimental approach to delve into how habits affect strategic communication. The third chapter investigates the influence of irrelevant information on individuals' valuation of goods, exploring whether market interactions mitigate this effect. The fourth chapter studies the decision-making process surrounding the disclosure of information pertaining to corporate fraud through whistleblowing mechanisms. Through these diverse topics, this dissertation contributes to the broader understanding of how information intersects with economic decision-making processes.
