In East Africa, the development of the bicycle and motorcycle taxi (boda-boda) service can be seen as a spontaneous entrepreneurial response to the increased availability of bicycles and motorcycles. Concomitant with the increasing number of boda-boda operators is the escalating passenger safety concern. A needs assessment survey instrument was administered to randomly selected motorcycle boda-boda operators from a Kampala suburb (Kalerwe and Bwayise locations). Besides safety, the questionnaire addressed issues related to preferred equipment type, ownership, operator training, profitability and operators' attitudes toward organised association. The results of the study support the notion that it is difficult for boda-boda operators to make substantial improvements in their incomes. The results also illustrate the importance of this emerging cottage industry to the local economy. However, more needs to be done to protect the public and to enhance the boda-boda operators' professionalism. 相似文献

This article sets out to demonstrate that every economy at a specific time has its inherent, quite definite, rate of inflation. Inflation rates may vary widely depending on economic situation and should be estimated in a dynamic perspective. They include a component associated with the degree of transformation of production facilities, which determines the “normal” rate of inflation. Another component, reflecting the influence of extra investment, which may prove necessary to compensate for the previous period of decapitalization of the Russian economy, varies through the investment cycle. This makes it possible to forecast inflation fluctuations around the “normal” rate; their recognition should be the basis for establishing a socially and politically acceptable rate of inflation within a particular development strategy. 相似文献
