Service provision for street-based traders in Pietermaritzburg,KwaZulu-Natal: comparing local findings to lessons drawn from Africa and Asia

South Africa's informal economy absorbs approximately one-quarter of the labour force of 15 million people and is therefore the fastest growing sector of employment. Street-based trading constitutes a major subsector within the informal economy and is continuously expanding through unrelenting proliferation of survivalist micro-enterprises. However, few organisations that support enterprises are accessible or appropriate to survivalist and informal sector micro-enterprises. Interviews were conducted with 98 Pietermaritzburg street-based traders and ten KwaZulu-Natal service providers to determine service provision requirements. The results are compared with findings of four international studies. The findings suggest that for survivalist enterprises to benefit from entrepreneurial education and training services, obstacles with regard to South African traders' understanding of entrepreneurship and cultural limitations to enterprise growth should be overcome. Service institutions also require incentives to serve the informal sector, as well as the capacity to design and deliver appropriate services.     

Mortgage Terminations and Pool Characteristics: Some Additional Evidence

The amount and timing of unscheduled principal amortization determines the ex-post yield to holders of mortgage-backed securities. In this paper, the relationship between pool characteristics and the early return of principal is addressed. Empirical results are based on actual terminations from June 1985 to June 1986 on a sample of all GNMA pools. The relative termination experience of pools with loan rates close to the refinancing rate faced by the underlying borrower is examined in detail. The impact of pool age and size is also considered. Unscheduled termination depends on the refinancing rate, as well as the specific characteristics of a pool.     

THE DIFFERENTIAL EFFECTS OF SINKING FUNDS ON BOND RISK PREMIA

This study analyzes the effect that two options created by the inclusion of a sinking fund clause in a bond indenture have on the bond issue's secondary market risk premium. The impact of market prices that exceed current sinking fund redemption prices, and of par versus premium redemption, is clearly apparent when a set of issue-specific and macroeconomic control variables are incorporated into a model of bond risk premia. Thus, secondary market prices for the large-volume utility bond transactions in the sample reflect knowledge of individual-issue, time-varying indenture characteristics.     

A survey of cross-sectional and time-series literature on factors affecting child welfare

This paper reviews the literature on the socio-economic determinants of child welfare. Cross-sectional evidence is first analysed. The relevant literature is subdivided into four groups of studies depending on the main factors influencing child welfare: demographic; related to family circumstances; related to health care and sanitation; and economic. The very few time-series studies on this subject are then examined. While the existing literature does not allow definitive conclusions to be drawn on the predominance or relative importance of these four sets of factors, this paper identifies three related research areas for which particularly severe gaps seem to emerge and for which additional investigation appears necessary. These are: over-time studies, studies for low-income, high-mortality countries of Africa, for middle-income countries and for high-income, high-mortality countries, and studies measuring impact on the basis of indicators of welfare other than infant mortality rates.
