This paper analyzes the causes and implications of recent financial crises. Financial crises in general lead to changes in both theory and practice of economics. The paper takes an historical overview. The global consensus of economic theory during the 20th century is discussed. The paper...

In these notes I go over some basic aspects of the analysis of business cycles and aggregate fluctuations from a dynamic stochastic general equilibrium (DSGE) perspective. I build a cannonical DSGE model with a small number of representative agents and a large set of distortionnary wedges...

We show how a Schumpeterian process of creative destruction can induce coordination in the timing of entrepreneurial activities across diverse sectors of the economy.Consequently, a multi-sector economy, in which sector-specific, productivity improvements are made by independent, profit-seeking...

Why have the Euro area and the US diverged since 2011 while they were highly synchronized during the recession of 2008-2009? To explain this divergence, we provide a structural interpretation of these episodes through the estimation of a business cycle model with financial frictions for both...

We address an important business cycle fact, i.e., the amplified and hump-shaped responses of output to productivity shocks, in a dynamic general equilibrium model with financial frictions. Models with financial frictions in the current literature have either the amplification mechanism or the...
