We apply non-linear error-correction models to the empirical testing of the sustainability of the government's intertemporal budget constraint. Our empirical analysis, based on Italy, shows that the Italian government is meeting its intertemporal budget constraint, in spite of the high levels of...

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 literature on fiscal policy sustainability by introducing non-linear fiscal reaction functions with endogenously estimated state-varying thresholds to capture the behaviour of fiscal policy authorities during "good" and "bad" times. These thresholds vary with the level of...

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...

I use a new measure of surprise foreign official Treasury purchases, high-frequency data, and identification by heteroskedasticity to estimate the effect of Chinese official purchases of US Treasury securities on Treasury yields. Over the past decade, foreign official institutions have purchased...

I employ a sign-identified vector autoregression (VAR) in foreign Treasury purchases and factors of the yield curve to estimate the dynamic impacts of foreign Treasury purchases on Treasury yields. Although a growing literature studies this question, it does not adequately address the...
