As noted by Alan Greenspan in 2008, one key flaw in standard models is that they treat animal spirits as a simple 'add factor' rather than as a structural one. This paper evaluates the extent to which two recent approaches placing the emphasis on animal spirits - namely Farmer's...

In this paper, we analyze the impact of external uncertainty shocks on the Korean economy, focusing on Russian geopolitical risks and U.S. monetary policy uncertainty. We find that increases in external uncertainties negatively affect the Korean macroeconomy, with a particularly pronounced...

In the present paper, we study how the dynamics of Foley’s model may be affected by the introduction of a money wage Phillips curve with a perfect spill-over of price inflation on wage inflation. The upshot is a model with endogenous price and wage dynamics with unstable equilibrium, meaning...

In this paper, we look for the relevance of chaos in the well-known Hicks-Samuelson's oscillator model investigating the endogenous fluctuations of the national income between two limits: full employment income and under-employment income. We compute the Lyapunov exponent, via Monte-Carlo...

The subprime loan mortgage crisis has revived scholarly interest in Minsky's financial instability hypothesis. The related mathematical models present two types of Minskian financial structures. We construct macrodynamic models that consider both structures and discuss financial instability and...

This paper studies how tax-and-transfer progressivity influences aggregate fluctuations when interacting with household heterogeneity. Using a simple static model of the extensive margin labor supply, we analytically characterize how a degree of progressivity influences differential labor supply...
