This paper examines dynamic patterns of investment in Cameroon, Ghana, Kenya, Zambia and Zimbabwe, assessing the consistency of those patterns with different adjustment cost structures. Using survey data on manufactured firms, we document the importance of zero investment episodes and lumpy investment. The proportion of firms experiencing large investment spikes is significant in explaining aggregate manufacturing investment. Taken together, evidence from descriptive statistics, average investment regressions modeling the response to capital imbalance, and transition data analysis indicate that irreversibility is an important factor considered by firms when making investment plans. The picture is not unanimous however, and some explanations for the mixed results are proposed.

Our Continent, Our Future presents the emerging African perspective on this complex issue. The authors use as background their own extensive experience and a collection of 30 individual studies, 25 of which were from African economists, to summarize this African perspective and articulate a path for the future. They underscore the need to be sensitive to each country's unique history and current condition. They argue for a broader policy agenda and for a much more active role for the state within what is largely a market economy. Finally, they stress that Africa must, and can, compete in an increasingly globalized world and, perhaps most importantly, that Africans must assume the leading role in defining the continent's development agenda.

This is the final issue for 2006 (Volume 53), and contains another paper in the occasional Special Data Section that seeks to measure financial development in the Middle East and North Africa by utilizing a new database. The issue also contains a comment from Jacques J. Polak on parity reversion in real exchange rates.

Publisher description

"In the early 1990s the World Bank launched the Regional Program on Enterprise Development in several African countries, a key component of which was the collection of manufacturing firm-level data. In this paper the authors review the research based on the data sets generated by these and subsequent firm surveys in Africa, with a special view to what they think are the most important policy implications. The authors survey the research on the African business environment, focusing on market size, risk, access to credit, labor, and infrastructure. They cover the research on how firms choose to organize themselves and how firms do business. They review the research on firm performance, including firm growth, investment and technology acquisition, and exports. They conclude with an extended discussion of the policy lessons.

Research activity in the IMF emphasizes the links between the organization's policy and operational concerns. The main objectives of research is IMF staff understanding of policy and operational issues relevant to the institution, and to improve the analytical quality of the work prepared for management and the Executive Board and the advice provided to member countries. The scope of research in the IMF is defined by the purposes and functions of the institution. In order to foster innovation and ensure quality control, the IMF makes much of its research available outside the institution and encourages staff to interact with academia and other research organizations through conferences, seminars, and occasional joint research projects. The visiting scholar’s program has also enhanced the quality of research done in the IMF. This program brings in leading members of the economics profession from around the world to assist in the preparation of papers for the Executive Board and to conduct research on IMF-related issues.
