We develop a multicountry model in which governments aim at excessive spending in order to serve the narrow interests of the group in power. This puts pressure on the monetary authorities to extract seigniorage, and thus affects the incentives countries would have to participate in a monetary...

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)...

This paper investigates the medium- and long-term growth effects of the global financial crises on Low-Income Countries (LICs). Using several methodological approaches, including impulse response function analysis, growth spells techniques and panel regressions, we show that external demand (ED)...

This paper investigates the short-run effects of the 2007-09 global financial crisis on growth in (mainly non-fuel exporting) low-income countries (LICs). Four conclusions stand out. First, for many individual LICs, 2009 was not extraordinarily calamitous; however, aggregate LIC output declined...

This paper develops a full-fledged cost-benefit analysis of monetary integration, and applies it to the currency unions actively pursued in Africa. The benefits of monetary union come from a more credible monetary policy, while the costs derive from real shock asymmetries and fiscal disparities....

Since the turn of the century, aid flows to Africa have increased on average and become more volatile. As a result, policymakers, particularly in post-stabilization countries where inflation has only recently been brought under control, have been increasingly preoccupied with how best to deploy...

Since 1999, the IMF's staff has been tracking several early-warning-system (EWS) models of currency crisis. The results have been mixed. One of the long-horizon models has performed well relative to pure guesswork and to available non-model-based forecasts, such as agency ratings and private...

We focus on the management of highly persistent shocks to aid flows, including PRSP-related increases in net inflows, in three “post-stabilization.” African economies with de jure flexible exchange rates. Such shocks have beneficent long-run effects, but when currency substitution is high...

This paper assesses the non linear impact of external debt on growth using a large panel data set of 93 developing countries over 1969–98. Results are generally robust across different econometric methodologies, regression specifications, and different debt indicators. For a country with...

This paper investigates the channels through which debt affects growth, specifically whether debt affects growth through factor accumulation or total factor productivity growth. It also tests for the presence of nonlinearities in the effects of debt on the different sources of growth. We use a...
