The Relationship between Tax Revenues and Government Expenditures in European Union and Non-European Union OECD Countries

This article examines the causal relationship between tax revenues and government expenditures in twenty-two OECD countries, eleven European Union (EU) member states, and eleven non-EU. We use the Autorgressive Distributed Lag (ARDL) bounds test and the Toda-Yamamoto Granger noncausality approach to test for causality. The results show that the long-run and short-run causal patterns differ across these groups within the Organisation for Economic Co-operation and Development (OECD). For the long-run causal patterns, we find evidence to confirm the tax-and-spend hypothesis in eight of the twenty-two countries; but the evidence is more prevalent within the EU countries, where tax burdens are much higher, than in the non-EU OECD countries. In addition, the long-run causality results also confirm the institutional separation hypothesis in twelve countries, with two-thirds coming from the non-EU OECD countries. While we have no evidence to support the fiscal synchronization hypothesis in the long run, the short-run results show evidence of fiscal synchronization in five out of twenty-two countries.
