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...

Starting from a theoretical model with importable, traded and nontraded goods, we identify a long run relationship among Greek imports, domestic activity and relative prices. The model supports weak exogeneity of relative prices which means that Greek importers take the price of imports as...

Starting from a theoretical model with traded and non-traded goods, a long-run labour demand equation is identifed, with employment being proportional to relative output and prices. Using Greek data, the model supports weak exogeneity of relative prices and fiscal expansion with respect to the...

Our purpose is to investigate how the European Central Bank (ECB) sets interest rates in the context of both linear and nonlinear policy reaction functions. This work contributes to the current debate on central banks having additional objectives over and above control of inflation and output....

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...

Evaluation of quantitative easing (QE) is difficult as it is only used in response to severe and unusual economic difficulties. Despite this, we argue that two main conclusions can be drawn from a sceptical reading of the evidence. First, large-scale asset purchases reduce government bond rates,...

We empirically test the hypothesis that stock market illiquidity affects real UK GDP growth using data over the period 1989q1-2012q2. We conduct our empirical exercise within a standard linear model as well as a non-linear model, which allows for regime switching behavior in terms of a liquid...

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...

We analyse UK monetary policy using monthly data for 1992-2010. We have two main findings. First, the Taylor rule breaks down after 2007 as the estimated response to inflation falls markedly and becomes insignificant. Second, policy is best described as a weighted average of a “financial...

A steady increase in financial market liquidity followed by a rapid reduction played a central role in the financial crisis that began in 2007. We present empirical evidence that the marked rise in liquidity in 2001–07 was due to large and persistent current account deficits and loose monetary...
