Theoretical analysis, empirical development and case studies show that room to manoeuvre stabilising macroeconomic policies during the COVID-19 crisis in the years 2020 and 2021 were fundamentally different in the Global South and Global North. The latter used extensive discretionary fiscal and...

Recent empirical evidence by Fieldhouse and Mertens (2024) points to a strong causal link between federal nondefense R&D funding and private-sector productivity growth, and large implied social returns to public R&D investment. We show that these high social return estimates broadly align with...

We evaluate the aggregate effects of a change in tariffs on the US and world economies when tariff revenue is used to enact fiscal reform. Our model combines a standard international model of fiscal policy with taxes and a dynamic model of trade participation and tariffs that allows for...

The large-scale war between Russia and Ukraine has increased global oil prices, signaling a new era of macroeconomic shock management for both developed and developing countries. Consequently, this study investigates the passthrough effect of oil prices on domestic inflation in selected African...

This paper develops a dynamic stochastic general equilibrium model to examine the quantitative macroeconomic implications of countercyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity which is the particular market failure justifying policy...

This paper contributes to the policy evaluation literature by developing new strategies to study alternative policy rules. We compare optimal rules to simple rules within canonical monetary policy models. In our context, an optimal rule represents the solution to an intertemporal optimization...

The United Kingdom employed the McKenna rule to conduct fiscal policy during World War I (WWI) and the interwar period. Named for Reginald McKenna, Chancellor of the Exchequer (1915-16), the McKenna rule committed the United Kingdom to a path of debt retirement, which we show was forward-looking...

The aim of this paper is to analyze the impact of government spending on the private sector, assessing the existence of crowding-out versus crowding-in effects. Using a panel of 145 countries from 1960 to 2007, the results suggest that government spending produces important crowding-out effects,...

This short piece discusses the results of simple regression analysis using cross country data to determine the factors that have influenced fluctuations in real output during the covid-19 pandemic period. Focus is on explaining not only output growth from 2020 to the first half of 2021, but also...

The Housing Provident Fund (HPF) is the largest public housing program in China. It was created in 1999 to enhance homeownership. This program involves a mandatory saving scheme based on labor income. Past deposits are refunded when the worker purchases a house or retires. Moreover, the program...
