In a recent paper, Bai and Perron (2006) demonstrate that their approach for testing for multiple structural breaks in time series works well in large samples, but they found substantial deviations in both the size and power of their tests in smaller samples. We propose modifying their...

This study analyzes key issues associated with large increases in aid, including absorptive capacity, Dutch disease, and inflation. The authors develop a framework that emphasizes the different roles of monetary and fiscal policy and apply it to the recent experience of five countries: Ethiopia,...

The World Bank and the IMF have adopted a debt sustainability framework (DSF) to evaluate the risk of debt distress in Low Income Countries (LICs). At the core of the DSF are empirically-based thresholds for each of five different measures of the debt burden (the “debt threshold approach”...

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 as those...

We develop a model to study the macroeconomic effects of public investment surges in low-income countries, making explicit: (i) the investment-growth linkages; (ii) public external and domestic debt accumulation; (iii) the fiscal policy reactions necessary to ensure debt-sustainability; and (iv)...

The integration of financial markets around the world over the past decade has posed new challenges for policymakers. The speed with which money can be switched in and out of currencies and countries has increased with the efficiency of global communications, considerably shortening the time...

We assess monetary regime options for Latin American countries. The costs of a common currency are likely to outweigh its benefits, as those countries face diverse economic shocks, do not trade much with each other, and are affected by common international financial shocks only to the same...

This paper tells the story of the Asian financial crisis by addressing four questions: What were the causes of the crisis, how did the crisis unfold, what were the policy responses, and what have been the outcomes? The paper takes the view that none of these questions can be understood without...

Many low-income countries continue to describe their monetary policy framework in terms of targets on monetary aggregates. This contrasts with most modern discussions of monetary policy, and with most practice. We extend the new-Keynesian model to provide a role for “M” in the conduct of...
