This paper analyzes empirically differences in the size of central bank boards across countries. Defining a board as the body that changes monetary instruments to achieve a specified target, we discuss the possible determinants of a board''s size. The empirical relevance of these factors is...

This paper surveys the economic literature on the scaling-up of aid to Africa. It provides a checklist of issues that need to be considered when preparing a long term macroeconomic projection for a country involving the assumption of a significant increase in aid. Such scaling-up scenarios are...

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...

Transfers to individuals were a larger part of the 2009 U.S. stimulus package than government purchases. Using a two-agent New Keynesian model, this paper shows analytically that the multiplier on targeted transfers to financially constrained households is (i) larger than the purchase multiplier...

In this paper, we revisit the effects of government spending shocks on private consumption within an estimated New-Keynesian DSGE model of the euro area featuring non-Ricardian households. Employing Bayesian inference methods, we show that the presence of non- Ricardian households is in general...

Using disaggregated data for the United States, this paper explores the effects of the variability of fiscal and monetary policy shocks. Higher variability of government spending shocks around a steady-state growth trend results, on average, in a decline in aggregate demand growth and inflation,...

This paper provides estimates of the government spending multiplier over the monetary policy cycle. We identify government spending shocks as forecast errors of the growth rate of government spending from the Survey of Professional Forecasters (SPF) and from the Greenbook record. The state of...

This paper investigates empirically the drivers of financial imbalances ahead of the global financial crisis. Three factors may have contributed to the build-up of financial imbalances: (i) rising global imbalances (capital flows), (ii) monetary policy that might have been too loose, (iii)...
