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.

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...

– A bridge between micro and macro estimates?
The Nordic model relies on high tax rates to finance an extensive welfare state. If labour supply elasticities are large, the burden of financing the model can be large even if, arguably, the practice of providing subsidised goods that support labour supply is likely to mitigate these effects. We...

– A counter-argument to the recommendation in the Mirrlees Review
The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This article examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...
This paper examines the effects of health-oriented food tax reforms on the distribution of tax payments, food demand and health outcomes. We offer an illustration of how one can take into account the uncertainty related to both demand estimation and health estimates and to produce confidence...
– Economywide Analysis for Ethiopia and Uganda
Rapid urbanization is an important characteristic of African development and yet the structural transformation debate focuses on agriculture’s relative merits without also considering the benefits from urban agglomeration. As a result, African governments are often provided conflicting...
– Evidence from a Group-Based Aid Project in Mozambique
This paper evaluates the impact of an intervention to improve farming techniques and food security in the Gaza area of rural Mozambique. We examine the impact of a group-based approach to technology adoption in subsistence agriculture, using panel data collected by our research team on over 200...
Fish stocks around the world are heavily overexploited in spite of fishing policies in several parts of the world designed to limit overfishing. Recent studies have found that the complexity of ecological systems and the diversity of species, as well as negative impact of fishing activities on...
– An Empirical Analysis
The theoretical analysis of optimal commodity taxation is advanced, but there is only limited empirical evidence to guide commodity tax policies. With this paper, we contribute to this body of literature by empirically examining, using Finnish consumption data, the relation between working hours...
