Despite investment in education appearing to be a more pressing need in many developing countries, spending on roads often exceeds that on schools. This column argues that the different pace with which roads and schools contribute to economic growth is central to governments’ optimal allocation decision. Investment in schools tends to lead to a larger long-run increase in output, but the effects are more delayed than for investment in roads. This trade-off contributes to the bias towards roads, in particular when government concerns about debt sustainability and policymakers’ myopia are taken into consideration.

Recent policy recommendations suggest that the output growth ‘bang’ for each additional ‘buck’ of public investment depends on the efficiency of public investment spending. This column argues that high-efficiency and low-efficiency countries may have similar growth impacts from additional public investment spending. This is because efficiency and scarcity of public capital are likely to be inversely related across countries. Efficiency and the rate of return need to be considered together in assessing the impact of increases in investment.

Electoral results and the geographical allocation of public investment in Greece have been intimately related. This column describes how incumbent Greek governments between 1975 and 2009 tended to reward those constituencies returning them to office. Increases in both the absolute and relative electoral returns for the party in government in a given Greek region were traditionally repaid with a greater level of per capita investment in that region. Single-member constituencies were the greatest beneficiaries of this type of pork-barrel politics.

Investment in the Eurozone is forecast to remain below trend until 2015, with a particularly large shortfall in the periphery. Low investment reduces aggregate demand, thus lowering short-term growth, and it also hampers medium-term growth through its effect on the capital stock. This column highlights three causes of low Eurozone investment – reduced public investment, financial fragmentation, and heightened uncertainty – and proposes a series of remedies.

In the debate over the pros and cons of government spending, the efficacy of public investment is a point on which many conclusions hinge. This column introduces a new Public Investment Management Index that benchmarks the quality and efficiency of the investment process across 71 developing and emerging countries.
