Previous literature suggests that leaders matter for growth in general. This paper asks which leaders matter and develops a methodology to estimate the growth contribution of individual leaders and calculate its precision. The findings show that few leaders have statistically significant...

Fiscal adjustment becomes like walking up the down escalator when growth-promoting spending is cut so much as to lower growth and thus the present value of future tax revenues to a degree that more than offsets the improvement in the cash deficit. Although short-term cash flows matter, a...

When foreign aid undermines institutional development aid recipients can exhibit the symptoms of aid "dependence" - benefiting from aid in the short term but damaged by it in the long term. The authors find that one equilibrium outcome can be high aid and weak institutions, even when donors and...

Despite a large body of research and evidence on the policies and institutions needed to generate growth and reduce poverty, many governments fail to adopt these policies or establish the institutions. Research advances since the 1990s have explained this syndrome, which this paper generically...

This paper uses a global general equilibrium simulation model to quantify the effects of lifting economic sanctions on Iran with and without strategic responses. Iran benefits the most, with average per capita welfare gains ranging from close to 3 percent, in the case when Iran's crude oil...

This paper develops a dynamic stochastic general equilibrium model to analyze and derive simple budget rules in the face of volatile public revenue from natural resources in a low-income country like Niger. The simulation results suggest three policy lessons or rules of thumb. When a resource...

If trade tensions between the United States and certain trading partners escalate into a full-blown trade war, what should developing countries do? Using a global, general-equilibrium model, this paper first simulates the effects of an increase in U.S. tariffs on imports from all regions to...

After an impressive acceleration in growth and poverty reduction since the mid-1990s, many African countries continue to register robust growth in the aftermath of the global financial crisis. Will this growth persist, given the tepid recovery in developed countries, numerous weather shocks, and...

Not only do Africa's fragile states grow more slowly than non-fragile states, but they seem to be caught in a "fragility trap" . For instance, the probability that a fragile state in 2001 was still fragile in 2009 was 0.95. This paper presents an economic model where three features -- political...

This paper examines the potential role of civil society action in increasing state accountability for development in Sub-Saharan Africa. It further develops the analytical framework of the World Development Report 2004 on accountability relationships, to emphasize the underlying political...
