This paper provides new evidence that the minimum wage has significant spillover effects on firms exposed to the minimum wage indirectly via firm supply chains. Using administrative firm-level tax data...

– Evidence from a large minimum wage increase in the agricultural sector using administrative tax data
This paper presents new evidence on the employment effects of a large increase in agricultural minimum wages in South Africa using anonymized tax data. We add to the minimum wage literature by differentiating employment effects resulting from the destruction of existing jobs and from the slower...

Some entry barriers in agricultural and agro-processing value chains, particularly for smallholder farmers and small/medium-sized processors, can be overcome with innovation and technology adoption. Technologies and innovation in these sectors have been both radical and incremental, ranging widely...

We estimate the impact of Malawi’s Farm Input Subsidy Programme using an economywide approach. We find potentially substantial net benefits with indirect benefits accounting for about two-fifths of total benefits. Due to these indirect benefits, the cut-off at which lower fertilizer yield response...

– Evidence from Artisanal Marine Fishing in Ghana
In most coastal developing countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could...

– Evaluating the Case of Mozambique to 2050
We apply a probabilistic approach to the evaluation of climate change impacts in the Zambeze River Valley. The economic modeling relies on an economywide modeling approach. Taking a distribution of shocks as inputs, we create hybrid frequency distributions of the potential economic impacts of...
