Recently, it has been suggested that the effect of government expenditure on private consumption is dependent on the level of public debt. More specifically, a higher public debt implies a less Keynesian response in private consumption. In this paper we investigate if this theory is supported by...

In this paper, we study the effects of fiscal policy during different fiscal policy regimes. More specifically, we investigate how different factors, such as size, duration and composition of fiscal changes, can alter the effects of fiscal policy on private consumption. Using an unbalanced panel...

In this paper, we investigate the effects of cross-sectional disturbance correlation on a previously suggested panel data stationarity test. We find that the previously suggested test has a serious size distortion if the disturbances to different cross sections are correlated. We suggest a new...

In this paper, we elaborate on the notion of effective consumption and its role in determining the outcome of fiscal changes. More specifically, we investigate whether government consumption, by acting either as a complement or a substitute to private consumption, can help explain the...

In this paper, we study the small sample properties of the panel data stationarity test of Hadri (2000). We find that the previously suggested moments, that are to be used when standardizing the panel data stationarity test, cause size distortions when samples are small and serial correlation in...

In the current paper, the finite-sample stability of various implementations of the KPSS test is studied. The implementations considered differ in how the so-called long-run variance is estimated under the null hypothesis. More specifically, the effects that the choice of kernel, the value of...
