In the General Theory, Keynes remarked that the economy's state depends on expectations, and that these expectations can be subject to sudden swings. In this work, we develop a multiple equilibria behavioural business cycle model that can account for demand or supply collapses due to abrupt...

In this work we analyze the short- and long-run effects of fiscal austerity policies, employing an agent-based model populated by heterogeneous, boundedly-rational firms and banks. The model, in line with the family of "Keynes+Schumpeter" formalism, is able to account for a wide array of macro...

I review the literature on financial speculation driven by belief disagreements from a macroeconomics perspective. To highlight unifying themes, I develop a stylized macroeconomic model that embeds several mechanisms. With short-selling constraints, speculation can generate overvaluation and...

We draw a straight line connecting financial shocks, capital investment decisions by firms, and change in measured aggregate productivity using a dynamic general equilibrium model. Data shows that post the 2008 crisis, firms changed their allocation between assets of varying depreciation rates...

What are the long-run aggregate effects of monetary shocks displaying throughthe credit channel of monetary policy? We address this question by investigatingthe transmission mechanism and estimating the dynamic behaviour of variablesrelated to credit and innovation. Then, we develop a DSGE model...
