This paper summarizes the policy lessons from applications of the Maquette for MDG Simulations (MAMS) model to two low income countries: Ghana and Honduras. Results show that costs of MDGs achievement could reach 10-13 percent of GDP by 2015, although, given the observed low productivity in the...

The goal of this paper is to understand better, at the empirical level, how public spending contributes to growth by focusing on both the level and composition of public spending, in connection to the dynamics of GDP per capita growth. It attempts to answer two specific questions: (a) What are...

Given that public spending will have a positive impact on GDP if the benefits exceed the marginal cost of public funds, the present paper deals with measuring costs and benefits of public spending. The paper discusses one cost seldom considered in the literature and in policy debates, namely,...

This paper presents a small-scale intertemporal model of endogenous growth that accounts for the composition of public expenditure and externalities associated with public capital. Government spending is disaggregated into various components, including maintenance, security, and investment in...

The authors propose a"bottom up"approach to link public investment programs with a class of macro models recently developed to quantify Strategy Papers for Human Development (SPAHD) in low-income countries. The methodology involves establishing constant-price projections of investment outlays...

Nigeria's oil boom has not brought an end to perennial stagnation in the non-oil economy. Is this the unavoidable consequence of the resource boom or have misguided policies contributed? This paper indicates that the extreme volatility of expenditure rather than Dutch Disease effects are behind...

This paper relies on the recently developed Maquette for Millennium Development Goals Simulations (MAMS) model to assess the consistency of alternative scaling-up and policy packages for growth and achievement of the Millennium Development Goals in Ghana. In the baseline scenario, Ghana's strong...

Recently, much attention has been paid in the literature on economic growth to the phenomenon of"conditional convergence,"the tendencies of economies with lower-level incomes to grow faster, conditional on their rate of factor accumulation. The author documents that, regardless of conditional...

The authors present an integrated macroeconomic approach to monitoring progress toward achieving the Millennium Development Goals (MDGs) in Sub-Saharan Africa. At the heart of their approach is a macroeconomic model that captures key linkages between foreign aid, public investment (disaggregated...

The design of effective aid programs depends on the diagnosis of the problem. To say that institutional failures are central to Africa's poor economic performance is not to repudiate early interpretations based on policy failures and capital shortages. Institutional failures produce policy...
