In response to the worst economic crisis since the 1930s, government budgets and central banks have provided substantial support for aggregate demand and for the financial sector. In the process, fiscal balances have deteriorated, government liabilities and central bank balance sheets have been...

We develop a model to analyze the macroeconomic effects of a scaling-up of aid and assess the implications of different policy responses. The model features key structural characteristics of low-income countries, including varying degrees of public investment efficiency and a learning-by-doing...

The size of government is a commonly used variable in many analytical studies on the effects of fiscal policy. An accepted practice is to measure it as the ratio of government spending to GDP. However, this is not the correct metric when computing the stabilization effects of nondiscretionary...

We develop a tractable open-economy new-Keynesian model with two sectors to analyze the short-term effects of aid-financed fiscal expansions. We distinguish between spending the aid, which is under the control of the fiscal authorities, and absorbing the aid-using the aid to finance a higher...

This paper presents, for the first time, multi-dimensional indices of the quality of budget institutions in low-income countries. The indices allow for benchmarking against the performance of middle-income countries, across regions, and according to different institutional arrangements that...

Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax revenue mobilization problems. This paper develops a dynamic stochastic small open economy model to analyze the macroeconomic effects of...

The current crisis calls for two main sets of policy measures. First, measures to repair the financial system. Second, measures to increase demand and restore confidence. While some of these measures overlap, the focus of this note is on the second set of policies, and more specifically, given...

We study the role of the exchange rate regime, reserve accumulation, and sterilization policies in the macroeconomics of aid surges. Absent sterilization, a peg allows for almost full aid absorption — an increase in the current account deficit net of aid—delivering the same effects...

Implementation of fiscal consolidation by advanced economies in coming years needs to take into account the short and long-run interactions between economic growth and fiscal policy. Many countries must reduce high public debt to GDP ratios that penalize longterm growth. However, fiscal...

Today’s record public debt levels in most advanced economies are not only a direct fall-out from the global crisis. Public debt had ratcheted up over many decades before, when it had been used, in most of the G-7 countries, as the ultimate shock absorber—rising in bad times but not...
