That was ‘rescue’. The task now is ‘recovery’. If that is to be sustained, strong and non-inflationary, it must be driven by private investment. In G7 countries, the bulk of investment is from the private sector, but this has declined substantially as a proportion of GDP, undermining productivity growth over recent decades. The central task for the recovery is to restore and sustain private investment. At the same time, we must recognise that one reason for the decline in both private investment and productivity has likely been the neglect of infrastructure investment. We now have huge opportunities from, indeed the imperative of, the drive to the zero-carbon and climate-resilient economy. • The first test of the soundness of public policy must be whether it fosters strong and sustainable private sector investment and provides the enabling infrastructure required to boost productivity growth. • The second test is fiscal responsibility. Sound management of the public debt of an economy is a prerequisite for both macroeconomic stability and national prosperity. Governments of both developing countries and advanced economies stand to benefit from having in place, and observing, medium-term strategies that anchor public debt and thereby secure investor confidence. Governments around the world, and certainly the G7 economies, are now finding themselves obliged to increase their expenditure sharply. This is in order to support incomes and livelihoods in the context of following health restrictions and the overall sharp economic shock contraction – the ‘rescue’ phase; and, once the impact of the pandemic abates, to restore confidence, ward off the threat of deep recession and re-establish growth – the ‘recovery’ phase. The G7 economies have suffered a historically severe shock as a result of the COVID-19 pandemic, most of them experiencing record annual contractions in 2020. For most G7 countries, this follows decades of slowing productivity growth and a cumulative shortfall of infrastructure spending. It also comes at a time of accelerating innovation in digital technologies, growing inequalities and the immense threat of climate change and other unexpected shocks made apparent by the current pandemic. But there are concerns that further borrowing could lead to unsustainable government debt and an increase in inflation, exposing economic strategies to further risks, especially when interest rates start to rise. We argue that: • The risks associated with higher public debt for advanced economies able to borrow in their own currency are currently substantially outweighed by the potential benefits from public action to drive investment for a sustained recovery. • The markets are signalling that there is no immediate problem in financing increased public borrowing. Despite nudging upwards, partly in response to President Biden’s ambitious US stimulus plan, real interest rates remain generally close to historic lows, all along the yield curve, reflecting the fact that globally the desired level of private sector saving in aggregate is low relative to the desired level of aggregate investment. • These historically low interest rates reflect the market’s hunt for returns and help greatly with the affordability of governments’ rescue and recovery expenditures. Private sector savers in the advanced economies did not see many opportunities for productive investment. Facing few attractive options for where else to put their money, they were willing to buy government debt at ever-diminishing rates of interest. Clearly the challenge is to put in place the incentives for private investment; a commitment to growth and sound and stable signals on the directions of policy, particularly around sustainable low-carbon and climate-resilient investment and innovation. 1 This investment, and the growth it brings, is desirable not only in its own right, but also because it helps to reduce the size of the public debt relative to growing GDP, the surest way to public debt sustainability over the long term. This will be easier for individual countries to pursue, and the resulting recovery will be stronger, if countries act together. Bond market ‘vigilantes’ are as likely to punish governments for lacking a sustainable growth strategy as they are likely to punish them for lacking fiscal restructuring plans. An historic opportunity to ‘crowd in’ private investment Governments must step in with sufficient ambition to provide the enabling environment to foster private investment, by investing in infrastructure, skills and intangible knowledge-generating assets. These investments must support the transition to sustainable and inclusive growth, advancing the fight against global threats, including infectious diseases, biodiversity loss and climate change. And resilience is crucial too as we are seeing around the world, whether it be floods, storms or fires, the need to adapt to the climate change that is occurring and will occur. Inadequate public investment has been a factor holding back private investment and preventing sustained and resilient productivity growth in key economies. The only route to growth without inflation is through investment in the economy’s productive capacity. A premature tightening of public budgets would almost certainly slow the pace of economic recovery. Economic stability comes through growth that is strong and sustained, and not at risk of faltering. It will be easier to pay back the debt while the economy is growing strongly. Once entrepreneurs can see that strong, sustainable economic growth is in prospect, they can be expected not only to start investing again in new capital stock but also to invest in the innovation process to accelerate the formation of the competitive business networks
