 My name is Alycee Lidwale. I am 27 years old and I come from France. Hello, my name is Epromio. I am 28 years old and from the United States of America. Hola, my name is Felico Kochen. I am 30 years old and I'm from Mexico. I study at Stanford University. My research interests are in macroeconomics and household finance. I'm a PhD student at the IAS at Stockholm University. Through my research, I look at how firms respond to monetary policy decisions. Interests are in macroeconomics of inequality, labor markets and optimal taxation. In this project, I study how Regiginating Job Stability affects the optimal design of French resistance. In my paper, I find that issuing a central bank digital currency while conducting quantitative easing could decrease lending and render a central bank's balance sheet difficult to tamper. In this paper, we propose a new framework in which we allow for boundary rationality and household heterogeneity. Our model is consistent with recent empirical findings on the effectiveness and the transmission mechanisms of monetary and fiscal policy. In my work, I show that the change in U.S. firms' belief formation around the mid-1980s can help us understand two empirical challenges in the literature. The fall in inflation persistence and the flattening in the Phillips Group. In my work, I show that country-specific features of the housing and mortgage markets are key determinants of the local impact of monetary policy.
