Essays on monetary theory

Abstract

In this thesis, we use mechanism design approach in order to study economies in which optimal mechanism bears some resemblance to actual monetary system. More precisely, we study optimal monetary policy in models in which either: money is essential, or, money and bonds are coessential. In the first chapter, we study an optimal intervention in a model of outside money. Next, we extend the model to include bonds and interpret its role. Finaly, the last chapter we discuss the problems with the usual modeling aproach to monetary policy transition and its implications
