This paper investigates the consequences of the 2004 locust plague in Mali. We argue that in agricultural economies with a single harvest per year, this type of shock can affect households through two channels: first, a speculative/anticipatory effect that kicks in during the growing season,...

We argue that risk sharing motivates the bankwide structure of bonus pay. In the presence of financial frictions that make external financing costly, the optimal contract between shareholders and employees involves some degree of risk sharing whereby bonus pay partially absorbs negative earnings...

While it is commonly thought that patrilocality is associated with worse outcomes for women and their children due to lower social support, few studies have examined whether the structure of female social networks covaries with post-marital residence. Here, we analyse scan sample data collected...

Despite the central role of self-assembled groups in animal and human societies, statistical tools to explain their composition are limited. The authors introduce a statistical framework for cross-sectional observations of groups with exclusive membership to illuminate the social and organizational...

Most low- and middle-income countries are characterised by a large informal sector, which implies that a substantial fraction of economic activity in these countries is completely unregulated. This has important implications for the behaviour of firms, workers, families, and consumers, with these...

We study intertemporal trade-offs that health authorities (HAs) face when considering the control of an epidemy using innovative curative medical treatments. We set up a dynamically controlled Susceptibles-Infected-Recovered (SIR) model for an epidemy in which patients can be asymptomatic, and we...

In a trade model with endogenous emissions abatement, we investigate the impact of three policy instruments aimed at mitigating carbon leakage: free emission allowances, Carbon Border Adjustment Mechanism (CBAM) and CBAM with export rebates. We show that providing allowances for free does not alter...

We model the evolution of preferences guiding behavior in pairwise interactions in group-structured populations. The model uses long-term evolution theory to examine different interaction scenarios, including con-ditional preference expression upon recognition of the partner’s type. We apply the...

The growing influence of internet platforms acting as content aggregators is one of the most important challenges facing the media industry. We develop a simple model to understand the impact of third-party content bundling by a social platform that has a monopoly on showing user-generated content...
