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...

– 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...

Households in developing countries use a variety of informal mechanisms to cope with risk, including mutual support and risk-sharing. These mechanisms cannot avoid that they remain vulnerable to shocks. Public programs in the form of food aid distribution and food-for-work programs are meant to...
Working Paper
pdf
In this paper we review the evidence on the impact of large shocks, such as drought, on child and adult health, with particular emphasis on Zimbabwe and Ethiopia. Our focus is on the impact of shocks on long-term outcomes, and we ask whether there are intrahousehold differences in these effects. The...

– The Director's Cut
Traditional poverty measures neglect several important dimensions of household welfare. In this paper we construct a measure of ‘vulnerability’ which allows us to quantify the welfare loss associated with poverty as well as the loss associated with any of a variety of different sources of...

We use public transfers in the form of food aid to test for the presence of risk sharing arrangements at the village level in rural Ethiopia. We reject perfect risk-sharing, but find evidence of partial risk-sharing via transfers. There is also evidence consistent with crowding out of informal...
Working Paper
pdf
Many argue that poverty is intimately linked with ‘vulnerability’. Still, there is no consensus about how to define and measure ‘vulnerability’. We review theory and describe strengths and limits of recently proposed measures. We then propose a definition of vulnerability and develop a general...

In economic literature insurance networks are often treated as exogenous institutions. Frequently, the assumption is made that some clearly identifiable group (e.g. ‘the whole village’ or ‘the extended family’) constitutes an insurance network. Still, theory suggests that the formation of insurance...

We examine a simple extension to existing credit contacts for the poor (‘microfinance contracts’), that would allow financial institutions to provide repayment insurance to their clients. The proposed contract uses the repeated nature of loans to build credit records that borrowers in good standing...

The work has influenced debate on safety net design world-wide and has driven scholarly agendas on household economics. This paper critically surveys work to date and...

The paper considers the macroeconomic impact of shocks to agricultural output and of negative and positive price shocks. It is shown that negative price shocks have particularly large externalities: it is estimated that the overall impact of these negative shocks on GDP may well be double their...
