The authors use a computable general equilibrium model to estimate the marginal cost of public funds (MCF) for taxes on domestic goods, exports, imports, capital, and labor in 38 African countries. The resulting MCF estimates provide directions for tax reform in Africa. The authors investigate...

Tobacco taxes are usually considered regressive, as the poorest individuals allocate larger shares of their budget toward the purchase of tobacco-related products. However, because these taxes also discourage tobacco use, some of the most adverse effects and their economic costs are reduced,...

Tobacco-use-related diseases are the main cause of mortality in Moldova, where tobacco consumption is widely spread, especially among men. In addition to health concerns, tobacco consumption has economic consequences, as households spend substantial resources on tobacco and related out-of-pocket...

This paper uses a randomized information intervention to shed light on whether poor understanding of social insurance, both the process of enrolling and costs and benefits, drives the relatively low rates of participation in urban health insurance and pension programs among China's rural-urban...

Climate risk is an important driver of long-term poverty dynamics, especially in rural regions. This paper builds a dynamic, multi-generation household model of consumption, accumulation, and risk management to draw out the full consequences of exposure to climate risk. The model incorporates...

Social protection systems in Latin America have been transformed in the past two decades. Until the 1980s, those who were not covered by the social security arrangements available primarily in the urban formal sector received little public assistance beyond universal subsidies for some food or...

The authors revisit the debt overhang question. They first use nonparametric techniques to isolate a panel of countries on the downward sloping section of a debt Laffer Curve. In particular, overhang countries are ones where a threshold level of debt is reached in sample, beyond which (initial)...

Using panel data models, the author examines the threshold effects of the productivity of infrastructure investment in developing countries. He considers various specifications of an augmented production function that allow for endogenous thresholds. More precisely, these specifications are...

The authors propose four economic principles for use in deciding taxing responsibilities for various levels of government. These are: 1) efficiency of the internal common market - for efficiency in internal common market, taxes on mobile factors and tradable goods should either be assigned to...

This paper evaluates how the Philippines utilize social protection systems and programs to help households better manage disaster risk. Exposure and vulnerability to natural disasters and the effects of climate change are particularly high in the Philippines. At the same time, the Philippines...
