THE NATIONAL INCOME AND EXPENDITURE OF SOUTH—WEST AFRICA (1920–1956)

T his ARTICLE SETS out provisional national accounting data prepared recently for South-West Africa and describes briefly the main sources and steps involved in deriving tlie estimates. Some attention will also be given to the question of reliability, but in viewof considcrationsof space no efTort will be made to discuss the estimating problems encountered or to examine the results obtained.     

RATES OF RETURN TO EDUCATION IN BOTSWANA: RESULTS FROM THE 2002/2003 HOUSEHOLD INCOME AND EXPENDITURE SURVEY DATA SET

Using the most recent Household Income and Expenditure Survey data (2002/2003), this paper presents current rates of return to education for Botswana. The results show that the rates of return have in general declined by one percentage point on average between the periods as shown in Table 2 . If we, however, look at the averages for the different school cycles, the fall in the average rates is quite significant at about six percentage points between the periods. The biggest fall is for secondary education, especially upper secondary education, which fell by 28 percentage points between the periods. The rates of return to tertiary education, however, rose by more than 50 percentage points. Ignoring upper secondary, the pattern of rates of return has remained similar to the results of the study based on the 1993/1994 data. Rates are higher for tertiary education and lower for secondary than for primary education. This results are still consistent with rates of return generally rising with level of education. At policy level, the results continue to support sharing of costs between Government and beneficiaries or their parents especially at tertiary education level. Second, the results indicate the need for the country to continue to vigorously pursue job creation and reorient the education system from emphasis on white collar jobs.

SOCIAL SECURITY AND WELL‐BEING IN A LOW‐INCOME ECONOMY: AN APPRAISAL OF THE KERALA EXPERIENCE

The State of Kerala, which is considered to have attained a level of social well‐being comparable to that of advanced countries despite its relatively low income standard, is widely known as an example of “welfare by public intervention” in developing economies. This paper, focusing on the four areas of food provision, health services, elementary education, and pension schemes, and paying attention to the participation of the private sector as well as the activities of political parties and labor unions, points out that in Kerala, the private sector and organized activities have played a vital role, in addition to “public intervention,” in the betterment of public welfare.     

AN ANALYSIS OF THE IMPACT OF PEDAGOGIC INTERVENTIONS IN FIRST-YEAR ACADEMIC DEVELOPMENT AND MAINSTREAM COURSES IN MICROECONOMICS

This paper analyses the impact of pedagogic interventions in first-year academic development and mainstream courses in microeconomics on students' performance in the final examination. The data for six cohorts, covering the years 1999 and 2001-2005, are pooled, and the Heckman two-part procedure is used to account for those students who started the course but did not write the final examination. The results suggest that the pedagogic interventions have a positive impact on the performance of academic development students relative to the mainstream cohort and on the performance of mainstream students.     

REGIONAL INCOME INEQUALITY IN INDONESIA AND THE INITIAL IMPACT OF THE ECONOMIC CRISIS

This paper estimates regional income inequality from 1993 to 1998, using a Theil index based upon district-level GDP and population data. Between 1993 and 1997, when Indonesia's annual average growth rate exceeded 7%, regional income inequality rose significantly. A two-stage nested inequality decomposition analysis indicates this was due mainly to an increase in within-province inequality, especially in Riau, Jakarta and West and East Java. In 1997, the within-province component represented about 50% of regional income inequality. The crisis caused per capita GDP growth to revert to its 1995 level, but the impact was spread unevenly across provinces and districts. In 1998 regional income inequality declined to its 1993-94 level. In contrast to 1993-97, three-quarters of the 1998 decline was due to a change in between-province inequality, with the Java-Bali region playing a prominent role. The crisis appears particularly to have afflicted urban Java and urban Sumatra.     

INCOME INEQUALITY, RECIPROCITY AND PUBLIC GOOD PROVISION: AN EXPERIMENTAL ANALYSIS

This paper analyses the impact of income inequality on public good provision in an experimental setting. A sample of secondary school students were recruited to participate in a simple linear public goods game where income heterogeneity was introduced by providing participants with unequal token endowments. The results show that endowment heterogeneity does not have any significant impact on contributions to the public good, and that consistent with models of reciprocity, low and high endowment players contribute the same fraction of their endowment to the public pool. Moreover, individuals appear to adjust their contributions in order to maintain a fair share rule.     

TAX REFORM AND THE PROGRESSIVITY OF PERSONAL INCOME TAX IN SOUTH AFRICA

This paper investigates the progressivity of personal income tax in South Africa over the period 1989 to 2003. We use the effective, redistributive and disproportionality measures of progressivity and find that progressivity of the tax system increased over the period 1990 to 1994. However, during the first phase of the reform programmes the results are inconclusive with the Kakwani index (disproportionality measure) showing increased progressivity. The redistributive effect measure, on the other hand, indicates a marginal decline in progressivity. During the second phase of the reform programmes, both techniques suggest a worsening in progressivity. One explanation for the decline in progressivity during the latter period in the analysis is the fact that many more “new” taxpayers entered the tax net (higher income groups in our database) which made the distribution of pre‐tax income more unequal thus impacting on progressivity. On the other hand, the disproportionality measure shows a continuous, albeit volatile increase in progressivity over the latter period under investigation.
