This article is the first to provide estimates of how minimum wages affect worker flows and employment growth rates in an employment scarce developing country context. We investigate the effects of a large, exogenous increase in agricultural minimum wages in South Africa. We find that changes...

– Poverty dynamics and inequality in South Africa between 2008 and 2017
Longitudinal surveys allow us to understand how markers of (dis)advantage determine present material welfare and economic upward or downward mobility over time. In this paper, we use five waves of panel data to empirically assess the extent and dynamics of poverty in South Africa between 2008 and...

This study explores the impact of the first wave of the COVID-19 pandemic in South Africa on income poverty and inequality in South Africa. Using a static tax-benefit microsimulation model with input datasets that were adjusted to reflect people’s earned incomes just before the pandemic (March 2020)...

– Rapidly increasing top incomes amid low national growth in South Africa
Despite South Africa’s need for inclusive economic growth, we find that the top income percentiles continue to diverge from the rest of the income distribution. We compare household survey data and tax data (which, unlike household survey data, includes accurate data for the very rich) to...

– Direct evidence using transaction data
This paper provides the first direct systematic evidence of profit shifting through transfer mispricing in a developing country. Using South African transaction-level customs data, the author directly tests for transfer price deviations from arm's-length pricing. It is found that multinational firms...
Journal Article
This paper investigates the process of adjustment in employment. A dynamic model is applied to a panel of six Tunisian manufacturing industries observed over a period of 25 years, from 1971 to 1996. Industries are assumed to adjust their labor inputs toward a desired level. A labor requirement...

– 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...
A considerable amount of recent work in political science and economics builds from the hypothesis that ethnic heterogeneity leads to poor provision of public goods, a key component of poor governance. Much of this work cites Alesina, Baqir and Easterly (1999) as providing empirical proof. This...
– an Exploratory Analysis
This article explores how ethnic politics may operate differently in societies with “ranked” versus “unranked” ethnic systems, where ethnicity and class correlate closely versus very little. It focuses on two hypotheses suggested, but not tested, in Donald Horowitz's Ethnic Groups in Conflict. Their...
