The theoretical literature generally finds that government spending multipliers are bigger than unity in a low interest rate environment. Using a fully nonlinear New Keynesian model, we show that such big multipliers can decrease when 1) an initial debt-to-GDP ratio is higher, 2) tax burden is higher, 3) debt maturity is longer, and 4) monetary policy is more responsive to inflation. When monetary and fiscal policy regimes can switch, policy uncertainty also reduces spending multipliers. In particular, when higher inflation induces a rising probability to switch to a regime in which monetary policy actively controls inflation and fiscal policy raises future taxes to stabilize government debt, the multipliers can fall much below unity, especially with an initial high debt ratio. Our findings help reconcile the mixed empirical evidence on government spending effects with low interest rates.

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that, in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as wasteful public spending or future commitments to low interest rates. (JEL E12, E43, E52, E62, H20)

We estimate the effects of government spending shocks during prolonged episodes of low interest rates, which we consider as proxy for the effective lower bound (ELB). Using a panel VAR model for 17 advanced countries, we find that both the government consumption and investment multipliers are significantly higher, and exceed unity, when interest rates are persistently low. Distinguishing between construction- and equipment-related government investments, we find that only the former raises output by significantly more when the ELB binds. This result can be explained by existing New Keynesian models featuring time-to-build constraints on government investment.


Around the world, people nearing and entering retirement are holding ever-greater levels of debt than in the past. This is not a benign situation, as many pre-retirees and retirees are stressed about their indebtedness. Moreover, this growth in debt among the older population may render retirees vulnerable to financial shocks, medical care bills, and changes in interest rates. Contributors to this volume explore key aspects of the rise in debt across older cohorts, drill down into the types of debt and reasons for debt incurred by the older population, and review policies to remedy some of the financial problems facing older persons, in the United States and elsewhere. The authors explore which groups are most affected by debt, and they also identify the factors causing this important increase in leverage at older ages. It is clear that the economic and market environments are influential when it comes to saving and debt. Access to easy borrowing, low interest rates, and the rising cost of education have had important impacts on how much people borrow, and how much debt they carry at older ages. In this environment, the capacity to manage debt is ever more important as older workers lack the opportunity to recover for mistakes.

The Special Issue aims to highlight the interaction between actuarial and financial mathematics, which, due to the recent low interest rates and implications of COVID-19, requires an interlace between actuarial and financial methods, along with control theory, machine learning, mortality models, option pricing, hedging, unit-linked contracts and drawdown analysis, among others [...]

This article outlines a counter-cyclical innovation strategy to achieve prosperity, derived from an innovative project, the California Institute for Regenerative Medicine (CIRM). We identify an ‘innovation paradox’ in that the very point in the business cycle, when legislators are tempted to view austerity as a cure for economic downturns and to reduce innovation spend, is when an increase is most needed to create new industries and jobs and innovate out of recession or depression. It is both desirable and possible that policymakers resist the urge to capitulate to the innovation paradox. During periods that exhibit subdued inflation, elevated spare productive capacity, and low government borrowing rates, governments should increase their borrowings and use the proceeds to boost investment targeted towards innovation. We show how the State of California successfully utilized debt financing, traditionally reserved for physical infrastructure projects, to stimulate the development of intellectual infrastructure. Finally, we recommend a halt to European austerity policies and a ‘triple helix’ broadening of narrow ‘smart specialization’ policies that chase a private venture capital chimera. Europe should seize the present macroeconomic opportunity of low interest rates, borrow for innovation and be paid back manifold by ‘picking winners’, similarly to what the USA has been doing through DARPA (Defense Advanced Research Projects Agency) with GPS, as a response to Sputnik, the Internet and artificial intelligence, or the driverless car, formerly known as the ‘autonomous land vehicle’ in its military guise. Proactively targeted macroscopic investments in innovation are needed to solve the productivity/employment puzzle and foster the transition to a knowledge-based society.

Significance With an election due soon, the governing Liberal-National Coalition’s pledge to ring-fence the defence spending commitments made in 2016 was under some pressure. However, defence spending in fiscal year 2021/22 will grow by over 4% in real terms and stay above the symbolic level of 2% of GDP. Impacts Growing popular and bipartisan concern with Chinese aggression is a conducive environment for increased defence spending. Low interest rates and a stronger Australian dollar are also supporting sustained levels of defence expenditure. Washington may increase pressure on Australia to conduct freedom of navigation exercises in the South China Sea. Major business groups are concerned that increased criticism of China in national politics will produce yet more punitive backlash.
