This paper characterises the jointly optimal monetary and fiscal stabilisation policy in a new Keynesian model that allows for consumers who lacking access to asset markets consume their disposable income each period. With full asset market participation, the optimal policy relies entirely on...

We analyse optimal discretionary games between a benevolent central bank and a myopic government in a New Keynesian model. First, when lump-sum taxes are available and public debt is absent, we show that a Nash game results in too much government spending and excessively high interest rates,...

We study the welfare properties of an economy where both monetary and fiscal policy follow simple rules, and where a subset of agents is borrowing constrained. The optimized fiscal rule is far more aggressive than automatic stabilizers, and stabilizes the income of borrowingconstrained agents,...

The paper presents a model of fiscal dominance with borrowing constraints, and provides evidence for a large number of sub-Saharan African countries on the relative importance of fiscal and monetary determinants of inflation. Based on the dynamic response of inflation to different shocks,...

We develop a optimal rules-based interpretation of the 'three pillars macroeconomic policy framework': a combination of a freely floating exchange rate, an explicit target for inflation, and a mechanism than ensures a stable government debt-GDP ratio around a specified long run. We show how such...

This paper investigates the impact of fiscal shocks on inflation, using a large panel of 139 countries over the period 1970-2021. First, both headline and core measures of inflation increase in response to expansionary shifts in the fiscal policy stance. Second, we split the sample and observe...

The COVID-19 pandemic and the subsequent need for policy support have called the traditional separation between fiscal and monetary policies into question. Based on simulations of an open economy DSGE model calibrated to emerging and advance economies and case study evidence, the analysis shows...

Official accumulation of foreign reserves may be perceived as interventions to influence the exchange rate, undermining the credibility of floating exchange rates and inflation targets. This paper develops a theoretical framework to study the interaction between reserve accumulation and monetary...

This paper develops a structural macroeconometric model of the world economy, disaggregated into thirty five national economies. This panel unobserved components model features a monetary transmission mechanism, a fiscal transmission mechanism, and extensive macrofinancial linkages, both within...
