The problems of supplying water to third world cities: Bulawayo's water crisis

The current drought in central and southern Africa has focused attention on issues relating to the provision and supply of potable water. In the case of Bulawayo, Zimbabwe's second city, there is the very real prospect that water supplies may be exhausted before the onset of the next rainy season. This paper explores the background to this problem and shows how poor planning, financial constraints, and political intransigence have failed to keep pace with a policy aimed at the provision of water to the inhabitants in this expanding urban environment Alternative sources of supply. in particular a pipeline to the Zambezi River, are also investigated.     

Analyzing Cost Differences in Life Insurance

Several indexes for comparing the cost of life insurance policies are currently available. A variety of criticisms of these indexes has been offered. This paper identifies an additional problem: consumers may lack confidence in index values because they do not reconcile with data about company performance (e.g., lapse ratios, returns on invested assets). Analysis results suggest that policy costs are as much a function of actuarial manipulation for marketing advantage as of commonly cited textbook factors (mortality, interest, expenses) and competitive factors (lapse ratio, average policy size).

Not all trade restrictions are created equally

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these models to use iceberg transport costs as a general form of trade barriers that can be interchangeable with ad valorem tariffs. I show that this is not always an appropriate conclusion. Specifically, I illustrate that profit for an exporter is more elastic in response to tariffs than iceberg transport costs, which affects the entry/exit decision of firms. This has implications for welfare analysis and empirical specifications.     

Should multivariate early warning systems for banking crises pool across regions?

Most extant work on prediction of banking crises has utilised global samples, which are in turn dominated by observations from middle-income countries, and rely on a single estimator. However, economic and financial structures as well as the pattern of shocks may differ substantially across regions, while a range of specifications is desirable to check robustness. Accordingly, in this paper we test the implicit pooling assumption in earlier multivariate work on Early Warning Systems using both logit and binary recursive tree specifications separately for crises in Asia and Latin America, as well as the pooled sample. Results suggest markedly different crisis determinants across regions, implying global samples are inappropriate.
