Total factor productivity in South African manufacturing firms

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 its drivers in South Africa. The recent availability of firm-level tax administration data has made it possible to measure and analyse the productivity of manufacturing firms in South Africa for the first time. In this paper, we use firm-level data for the period 2010-13 to estimate total factor productivity in the South African manufacturing sector. We examine differences in the level and growth of productivity across manufacturing sub-sectors and examine the heterogeneity in productivity levels within sectors. Our analysis paves the way for future research into the factors driving productivity growth of manufacturing firms that will contribute to the evidence base of the reasons for the significant heterogeneity in measured firm performance, even within narrowly defined sectors and size groups

An agent-based simulation of the stolper–samuelson effect

We demonstrate that agent-based simulations can exhibit results in line with classic macroeconomic theory. In particular, we present an agent-based simulation of an Arrow–Debreu economy that accurately exhibits the Stolper–Samuelson effect as an emergent property. Absent of a Walrasian auctioneer or any other central coordination, we let firm and consumer agents of different types interact in an open, money-driven market. Exogenous preference shocks result in price and wage shifts that are in accordance with the general equilibrium solution, not only qualitatively but also quantitatively with high accuracy. Key to this achievement are three independent measures. First, we overcome the poor input synchronization of conventional price finding heuristics of firms in agent-based models by introducing sensor prices, a novel approach to price finding that decouples information exploitation from information exploration. Second, we improve accuracy and convergence by employing exponential search as exploration algorithm. Third, we normalize prices indirectly by fixing dividends, thereby stabilizing the system’s dynamics

The elasticity of substitution and labour-displacing technical change in post-apartheid South Africa

This paper uses normalized constant elasticity of substitution production functions to estimate the elasticity of substitution and labour-augmenting technical change in South Africa over the period 1994-2012. We find elasticities of 0.6-0.9 and positive labour-augmenting technical change, which results in an increase in capital's income share relative to labour. More broadly, we find total factor productivity (TFP) growth rates of between 1 and 2 per cent across industries, although we find no TFP growth in the mining sector. We also find that the sector with the highest TFP growth - agriculture - achieved this through shedding labour while steadily increasing output

Introduction to the South African Revenue Service and National Treasury firm-level panel

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: (i) company income tax from registered firms who submit tax forms; (ii) employee data from employee income tax certificates submitted by employers; (iii) value-added tax data from registered firms; and (iv) customs records from traders. These data sets constitute a significant and unique source for the study of firm-level behaviour in post-apartheid South Africa. We review the key data sources used to construct the panel, highlight some important questions that arise as a result of panel construction, discuss the biases in the resulting data, compare key aggregates in the panel to other data sources, and provide a descriptive overview of the tax records

Toepassing van artikel 85 van die Nasionale Kredietwet in ’n aansoek om summiere vonnis

Voor die inwerkingtreding van die Nasionale Kredietwet 34 van 2005 (NKW) in 2007 was dit ietwat ongehoord om in Suid-Afrika te hoor van wetgewing gerig op verbruikersbeskerming. Een van die NKW se hoofdoelstellings is die beskerming van skuldenaars. Skuldberading ingevolge artikel 86 is een van die wyses waarop die wetgewer aan sodanige beskerming uiting gee. Artikel 85 bepaal dat ’n hof, in enige verrigtinge waarin ’n kredietooreenkoms ter sprake kom en indien die skuldenaar beweer dat hy oorverskuldig is, die kredietooreenkoms na ’n skuldberader mag verwys of self die skuldenaar oorverskuldig verklaar en sy skuld herstruktureer. In die praktyk word artikel 85 hoofsaaklik by aansoeke om summiere vonnis met betrekking tot ontroerende eiendom deur skuldenaars geopper. Artikel 85 verleen aan die hof die diskresie om die kredietooreenkoms na ’n skuldberader te verwys met die gevolg dat summiere vonnis uitgestel of gewysig kan word. Die onus rus op die skuldenaar om die hof te oortuig om sodanige verwysing te beveel. Die howe het ’n aantal aspekte geïdentifiseer wat oorweeg moet word by die toepassing van die hof se diskresie. Hierdie artikel is ’n kritiese bespreking van artikel 85 asook die uitleg daarvan deur die howe.http://www.dejure.up.ac.za
