This paper studies price stability and debt sustainability when the real rate exceeds trend growth (r g) in a New Keynesian model with endogenous technology growth through R&D. Under debt-stabilizing ("passive") fiscal policy the Taylor principle is not sufficient for determinacy. Instead,...

We develop a Fiscal Frontier which traces out the maximum government debt level that can be sustained at a given welfare cost. Through duality, the intertemporal policy mix underpinning the Frontier mirrors standard Ramsey policy and defines an upper limit on the welfare gains that can be...

In March 2020, against the backdrop of a worsening Covid crisis, some segments of the money market fund (MMF) industry faced severe redemption pressures. Given their central role within the short term funding market, MMFs were at the heart of financial stability concerns, and legitimately...

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...

Long shunned as slow and ill timed, the response to the Covid-19 pandemic initiated a reassessment of fiscal policy as stabilisation tool. At the same time, there is ample evidence that major economic downturns produce lasting effects on real GDP in spite of active fiscal policy interventions....

This work investigates the role of local public investment in stimulating private investment and in providing support to growth and development. The analysis is based on a combination of datasets, allowing to build an unbalanced panel for 98 NUTS2 European regions in 13 member states, and for...

This paper analyses the magnitude of automatic income and demand stabilization in EU Member States between 2011 to 2019. Our analysis finds that automatic income stabilization in 2019 averaged 41.3 percent at the EU level, with considerable variation among Member States. While the extent of...

During the pandemic, African banks rebalanced their portfolio towards sovereign assets, and crowding out of credit to private sector intensified. Policy support, however, averted a credit crunch. The increase in public debt across Africa due to the COVID-19 crisis intensified crowding out of...
