Existing climate-economy models use aggregate damage functions to model the effects of climate change. This approach assumes climate change has equal impacts on the productivity of firms that produce consumption and investment goods or services. We show the split between damage to consumption...

Entrepreneurship scholarship and policy are based on the myth of firm growth as imperative and the related myth of perpetual economic growth. This paper takes issue with the obsession with this growth myth, discussing the dangers it poses. Green growth and sustainable entrepreneurship are...

When South Africa implemented its non-pharmaceutical interventions (NPIs) (its "lockdown") to stem the COVID-19 pandemic in March 2020, it was hailed as exemplary. By June 2020 however, the lockdown was in disarray: the number of confirmed infections continued to grow exponentially, placing the...

We provide evidence that lower fertility can simultaneously increase income per capita and lower carbon emissions, eliminating a trade-off central to most policies aimed at slowing global climate change. We estimate the effect of lower fertility on carbon emissions accounting for the fact that...

This paper discusses four dimensions of the economics of AI that are neglected in business school and university teaching and research. First, students are not being taught that there is no 4th Industrial Revolution; on the contrary, the narrative of the inevitability and wonders of the 4IR is a...

The productivity of non-farm enterprises in rural Africa may be associated with the productivity of other spatially proximate farm and non-farm enterprises. To test for the presence and significance of such spatial autocorrelation we use data from the geo-referenced 2011 Ethiopian Rural...

We are the first to provide a comparative empirical analysis of non-farm entrepreneurship in rural Africa, using the World Bank's unique LSMSISA dataset. This dataset covers six countries over the period 2005 to 2012. We find that rural enterprises tend to be small, informal household...

Africa is not only the poorest and most rural continent, it is also the most youthful continent in terms of population. Given the large number of young job seekers that will enter the labor market over the next decade, we need a better understanding of rural non-farm entrepreneurship,...

Although non-farm enterprises are ubiquitous in rural Sub-Saharan Africa, little is yet known about their productivity. In this paper we contribute to filling this gap by providing estimates of labor productivity in enterprises for Ethiopia, Malawi, Nigeria, and Uganda. Using the World Bank's...

In this paper, we study the crowdsourcing of innovation in Africa through a data science contest on an intermediated digital platform. We ran a Machine Learning (ML) contest on the continent's largest data science contest platform, Zindi. Contestants were surveyed on their motivations to take...
