Abstract
"This thesis consists of three chapters on the role of monetary and regulatory policies to deal with business cycle fluctuations and financial risk. Optimal mandates
are studied in the form of both simple policy rules and policy objectives formalized as loss functions. In addition to this mandates approach to policy, further
innovative features of the study are first, special attention paid to the design of rules that are robust to different variants of the model; second, in a model with a role for monetary and macro-prudential policy, the examination of coordinated versus uncoordinated mandates."
