Sub-Saharan African cities are among the fastest-growing in the world but face significant climatic risks. This study investigates how exposure to extreme climate events has shaped the economic, demographic, and physical growth of ~6 000 cities in the region between 2000 and 2020. Using high-resolution remote sensing data combined with a dynamic panel and event-study approach, I find that climate-driven shocks lead to accelerated informal settlement expansion and reduced economic growth, particularly in medium-sized cities with low resilience and higher poverty. In addition these shocks fuel food price inflation highlighting welfare implications. Finally, the paper documents heterogeneous responses to a chosen set of shocks depending on the location of businesses and households within cities. These findings underscore the need for urban policies also in mid-sized cities that enhance resilience to climate risks, particularly through improved adaptation to heat and through economic support for vulnerable urban populations.

This paper assesses the impact of an orderly environmental transition (ET) on the Euro area natural rate of interest (r*), which is a key benchmark for monetary policy, financing conditions and the social cost of carbon. To this end, we use high-frequency identification methods, isolating carbon policy shocks from EU ETS futures price variations around regulatory announcements. We also use a finance-based r* derived from dynamic term structure models estimated on the prices of inflation-indexed bonds. We find a significant and persistent increase in r* following a positive carbon policy shock. Specifically, according to our estimates, reaching a carbon price of €550 per ton of CO2 to reach Net Zero by 2050 could raise r* by 1.6 percentage points, ceteris paribus.

This article documents how the extraction of a labor-intensive commodity triggered urbanization in smaller, more remote, and poorer cities in sub-Saharan Africa. We leverage exogenous variation in the value of artisanal and small-scale gold mining (ASgM) activities – a widespread source of livelihood heavily dependent on the international market price – in a comprehensive panel of fine-grained cells starting in 1975. We find that locations with greater exposure to ASgM experience higher population growth and the emergence of more cities. These effects are driven by smaller cities (less than 50k inhabitants) and are particularly pronounced in isolated zones with a limited initial population. Focusing on cities, those with more ASgM tend to exhibit lower living standards and an employment structure still largely geared towards agriculture.

Algo-Rhythm Unplugged: Effects of explaining algorithmic recommendations on music discovery

Music streaming services make massive use of algorithms in their music recommender systems (MRS) to guide users to tracks that they are likely to enjoy. However, the black-box nature of these algorithms makes them difficult for users to understand, both in terms of how they work and the music they predict. The field of explainable AI (XAI), and in particular its “explanation” side, has emerged to make the uses of AI (including MRSs) more comprehensible to users. This paper aims to observe, using a laboratory experiment, whether the explanation of an MRS algorithm induces a change in discovery behavior on music streaming services. In a theoretical framework, we model two types of user discovery behavior, namely “study” and “browse” behaviors. We then test in the lab the explanation effects of these behaviors by explaining a simplified “semi-personalized” MRS and measuring the relative listening time of the tracks. Data shows no average effect induced by the explanations, but we observe a differentiated impact of explanations based on the treatment intensity (i.e. the time spent reading them). The more individuals are treated, the more they listen to the tracks, reinforcing the “study” behavior.
