Over the past three decades, public spending on infrastructure, as a share of GDP, has been on the decline worldwide. Although the link between infrastructure investment and economic growth is not yet fully understood, the quality of infrastructure clearly affects a country's productivity,...

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...

Fiscal problems have long been considered a central feature of financial--that is, currency, debt, and banking--crises. This paper addresses four questions: What are the fiscal causes of crises? Which fiscal vulnerability indicators help to predict crises? Can fiscal variables explain the...

The main purpose of this paper is to provide an overview of approaches to assessing fiscal sustainability. It summarizes the general analytical background, focusing on the present value budget constraint, which is the benchmark against which solvency is determined, tests of sustainability...

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...

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...

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...
