I am not aware of the foundational basis of the analysis referred to in the Deputy's question or the basis for the specific conclusion relating to the level of public expenditure relative to that in other EU states.
As the Deputy will be aware, there are important issues relating to differences in the composition of public expenditure in different jurisdictions affected by such factors as, for example, the age profile of the population, the level of defence spending and the mix between public and private provision of particular services that need to be taken into account in seeking to make cross-country comparisons.
Direct comparisons with public investment levels in Ireland under previous capital investment plans also need to be treated with caution, particularly when such plans are oriented towards addressing long-term infrastructural deficiencies, as was the example in the case of the period up to 2008.
In addition, the capacity constraints and levels of tender price inflation will impact on the real, compared to the nominal, level of public capital investment. Reflecting these considerations, trends in public capital investment should preferably be examined over a much more extended time horizon. In this regard, the ESRI which is regarded as the definitive examiner of these matters has reviewed investment levels in EU member states over more than four decades, from 1970 to 2013. It has found that Ireland ranks third behind Sweden and the Netherlands in terms of state investment in national infrastructure as a share of GDP.
The Government's capital plan, Building on Recovery: Infrastructure and Capital Investments 2016-2021, announced an Exchequer capital spend of €27 billion in the next six years. Supplementing Exchequer-funded investment with investment planned from the wider semi-State sector and PPPs means that total State investment will amount to €42 billion in the next six years. At the time of publication of the capital plan, State-backed capital investment, therefore, constituted a forecasted average of 3.5% of GDP per annum over the relevant period.
