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 note outlines a scheme for mobilizing financing to help developing countries confront the challenges posed by climate change. The idea is to create a “Green Fund” with the capacity to raise resources on a scale commensurate with the Copenhagen Accord ($100 billion a year by 2020). By...

Panel data on Ghanaian manufacturing firms are used to test predictions from models of irreversible investment under uncertainty. Information on the entrepreneur’s subjective probability distribution over future demand for the firm’s products is used to construct the expected variance of...

The economic effects of German unification are first discussed in the context of a global saving/investment model. Next, simulations of MULTIMOD are presented, suggesting for the FRG an initial increase in long-term real interest rates equal to 3/4 of a percentage point, increased output, a...

This paper examines credibility and reputational factors in explaining the December 1994 crisis of the Mexican peso. After reviewing events leading to the crisis, a model emphasizing the inflation-competitiveness trade-off is presented to explain the formation of devaluation expectations....

The effects of population aging are examined with the aid of a theoretical model and simulations of MULTIMOD. An older population will consume more of aggregate disposable income, require higher government expenditure, and decrease labor supply. These effects should raise real interest rates and...

Standard models of policy credibility, defined as the expectation that an announced policy will be carried out, emphasize the preferences of the policymaker, and the role of tough policies in signalling toughness and raising credibility. Whether a policy is carried out, however, will also...
