In this paper, we consider incidences of arrears to the IMF, focusing on protracted arrears cases and attempt to identify determinants of their occurrence. We use narrative and formal methods. In addition, we analyze determinants of the duration of arrears. We find that previous arrears, reserves coverage, and institutional quality are among the main determinants of arrears. In addition, we identify a role for political developments, including civil unrest, which make arrears more likely to arise and to last longer. We conclude that improved macroeconomic conditions and turnaround of political fortunes would help to clear the currently remaining protracted arrears cases.

This paper attempts to predict the incidence of arrears to the International Monetary Fund (IMF) by modifying and applying two of the major early warning systems for currency crises: the "signals" approach proposed by Kaminsky, Lizondo, and Reinhart (1997) and the probit-based alternative developed by Berg and Pattillo (1998). The results, based on both in-sample and out-of-sample tests, appear encouraging. While the unique nature of IMF arrears poses some challenges, the models could be useful tools for identifying countries at high risk of incurring arrears to the IMF.

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.
