This paper introduces a framework for studying the optimal dynamic allocation of foreign aid among multiple recipients. We pose the problem as one of weighted global welfare maximization. A donor in the North chooses an optimal path for international transfers, anticipating that consumption and...

Many countries have failed to use natural resource wealth to promote growth and development. They have been damaged by volatility of revenues, have failed to save a sufficiently high proportion of their resource revenues and failed to make high return investments to support diversification of...

We investigate the effects of short-term political motivations on the effectiveness of foreign aid. Donor countries’ political motives might reduce the effectiveness of conditionality, channel aid to inferior projects, reduce the aid bureaucracy’s effort, and change the power structure in...

A windfall of foreign aid or natural resource revenue faces government with choices of how to manage public borrowing, public asset accumulation, and the distribution of funds to households (across time and household types), particularly when the windfall is both anticipated and temporary. These...

In this Paper we focus on the question: Will the HIPC debt reduction program help in the transformation of the development assistance business and change the rules of the ‘debt game’ in Africa? We concentrate on the donor and official creditor side, by exploring how the growing debt of...

We construct and estimate a unified model combining three of the main sources of cross-country income disparities: differences in factor endowments, barriers to technology adoption and the inappropriateness of frontier technologies to local conditions. The key components are different types of...

We present a model in which two of the most important features of the long-run growth process are reconciled: the massive changes in the structure of production and employment; and the Kaldor facts of economic growth. We assume that households expand their consumption along a hierarchy of needs...

This paper examines a novel mechanism linking fertility and growth. There are three components to the model. First, increases in capital per worker raise women's relative wages, since capital is more complementary to women's labour input than to men's. Second, increasing women's relative wages...

The idea that income differences between rich and poor nations arise through multiple equilibria or ‘poverty traps’ is as intuitive as it is difficult to verify. In this Paper, we explore the empirical relevance of such models. We calibrate a simple two-sector model for 127 countries, and...
