We assess the sustainability of the public finances of Greece, Ireland, Italy, Portugal and Spain (GIIPS), allowing for possible non-linearities in the form of threshold behaviour of the fiscal authorities. We provide some evidence of fiscal sustainability when debt gets "too high" relative to a...

We extend previous work on the sustainability of the government's intertemporal budget constraint by allowing for non-linear adjustment of the fiscal variables, conditional on (i) the sign of budgetary disequilibria and (ii) the phase of the economic cycle. Further, our endogenously estimated...

This paper puts search frictions models under novel empirical scrutiny and tests their ability to match empirical observations. To capture changing dynamics we fit an extended Bayesian time-varying parameter VAR to US labour market data from 1962–2016. Our results indicate that these models...

This paper explores the decomposition of equilibrium unemployment into involuntary and frictional components using a model that combines efficiency wages with search and matching frictions in the labour market. In deriving our results we generalize the celebrated Solow Condition, expressing the...
