The South African Revenue Service and National Treasury Firm-Level Panel is an unbalanced panel data set created by merging several sources of administrative tax data received during 2015. The four data sources that constitute the panel are: company income tax from registered firms who submit tax...

The manufacturing sector is an important source of productivity growth and exports. Manufacturing firms are generally more productive than firms in the agricultural or services sectors and are an important source of job creation. Little is known about the productivity performance of the sector and...

– An analysis with administrative data
This paper uses newly available firm-level tax data to evaluate the market structure in South African manufacturing sectors in the period 2010–12. To describe the market structure we compute markups for South African manufacturing firms and concentration indexes for 4-digit manufacturing sectors. We...

– New evidence from South Africa
This paper uses firm-level data from company tax declarations to analyse the complementary relationship between direct access to imported intermediate inputs and manufacturing firm performance in South Africa. There are three main findings. The first is on firm heterogeneity, showing that importers...

Existing South African work on firm-level data has been limited by access to large datasets that track firms over time. This paper overcomes this by analysing a new dataset of the population of manufacturing firms that are matched to their export transactions. South African firm-level exporting is...

In this paper, worker and job flows are estimated using the IRP5 data from the South African Revenue Services. The data used in this paper is from the 2011–14 tax years and contains information on more than 12 million individuals and nearly 300,000 firms. The main finding of the paper is that worker...

– Evidence from South African tax registers
In this paper we study the effects of various tax schedule discontinuities on the behavior of small firms using high-quality and population-wide tax register data from South Africa. We use the bunching method to analyse how these discontinuities affect the firm-size distribution. We first examine...

The human development index (HDI) developed by the United Nations Development Programme is computed as the average of three equally weighted outcome measures: life expectancy (LI), educational attainment (EI) and income (WI). However, this computational process is independent of the resources being...

– a Sensitivity Analysis of Well-Being Indices
This paper attempts to provide a comprehensive analysis of interrelationships among the determinants of the quality of life (QOL). We show that various measures of well-being are highly sensitive to domains of QOL that are considered in the construction of comparative indices, and how measurable...

This study, relying on an economic-theoretical approach to index numbers, proposes a framework for incorporating environmental indicators to the measurement of human well-being. Furthermore this study also proposes an improvement index which alleviates the well-known deficiency of across-time...

This paper uses the data gained from an income categorization experiment for five shapes of income distributions to investigate background context effects, relative deprivation, range-frequency theory to explain background context effects, individual income satisfaction versus aggregate well-being...

Public policies often involve choices of alternatives in which the size and the composition of the population may vary. Examples are the allocation of resources to prenatal care and the design of aid packages to developing countries. In order to assess the corresponding feasible choices on normative...

Typical welfare and inequality measures are required to be Lorenz consistent which guarantees that inequality decreases and welfare increases as a result of a progressive transfer. We explore the implications for welfare and inequality measurement of substituting the weaker absolute differentials...

Basu and Foster (1998) characterized a sophisticated literacy measure using five axioms. In this paper we argue that if a measure satisfies three of their five axioms, namely, anonymity, monotonicity and externality, then also it becomes suitable in some applications. We, therefore, introduce two...

– A Problem in Measurement
This paper points to some elementary conflicts between the claims of interpersonal and intergroup justice as they manifest themselves in the process of seeking a real-valued index of poverty which is required to satisfy certain seemingly desirable properties. It indicates how ‘group-sensitive’...

This paper examines trends in income distribution and its linkages to economic growth and poverty reduction in order to understand the prospects for achieving poverty reduction in Africa. We examine the levels and trends in income distribution in some African countries and calculate pro-poor growth...
