Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper carries out a critical reappraisal of the two contending theories purporting to explain long-run government spending: Wagner’s Law and different variants of the ratchet effect. We analyze data spanning from the early 19th century until the present day in Sweden and the United Kingdom. Hence, in contrast to previous studies, we evaluate the validity of Wagner’s Law and the ratchet effect hypothesis over a very long time period, starting at the beginning of industrialization. Cointegration analysis is used to investigate the long-run relationships between government expenditure and GDP, focusing on sub-periods and parameter stability. Moreover, we test the ratchet effect hypothesis by estimating models which allow for asymmetric adjustment. According to our main results, Wagner’s Law does not hold in the long run, although the data are consistent with Wagner’s Law between roughly 1860 and the late 1960s in Sweden, and the 1970s in the UK. This can be traced to the formation of the modern public sector, including the introduction of public education, health care, and so forth. Yet Wagner’s Law did not hold during the initial industrialization phase (before 1860), or during recent periods. Finally, we find some evidence of asymmetric adjustment, particularly in the post WWII period in the UK: Public expenditure grows more during bad times than it decreases during good times. However, the ratchet effect is only a short to mediumterm phenomenon.
