Vanishing Third World Emigrants? [PDF]
This paper documents a stylized fact: the Third World has been undergoing an emigration life cycle since the 1960s, and, except for Africa, emigration rates have been level or even declining since a peak in the late 1980s and the early 1990s. The current

Oikos, EarlyView.Survival is commonly the most critical factor influencing population growth in long‐lived species. Hence, identifying factors shaping variation of survival rates is crucial to understand and predict population trajectories in a changing world. We investigated the factors influencing survival in a long‐lived diurnal bird of prey, analysing the effectsof

International Sanctions and Emigration
SSRN Electronic JournalIn this first empirical analysis of how sanctions affect international migration, we apply two estimation strategies, a panel difference-in-differences model and an event study approach. Our dataset covers 79,791 dyad-year observations, reflecting migration flows from 157 origin countries to 32 (largely OECD) destination countries between 1961 and 2018.

Quantifying community keystoneness in metacommunities under disturbance
Oikos, EarlyView.Understanding how metacommunities respond to natural and anthropogenic disturbances is a key objective in ecology. In this study, we introduce an analytical framework to identify communities whose extirpation triggers stronger (hereafter keystone communities) or weaker (hereafter idle communities) cascading effects on extinction and colonization events

Consumers and the Brain Drain: Product Design and the Gains from Emigration [PDF]
We consider the welfare effects of skilled worker emigration in a context where skilled labor plays a role in product design. We show such emigration can benefit the residents left behind, even when consumers’ tastes exhibit a form of home bias.

Oikos, EarlyView.During migration, migratory bird species often aggregate at the same stopover sites due to geographical features that channel migratory routes (coasts, valleys) or locally abundant food resources (e.g. reedbeds, fruiting bushes). In migration ecology, however, stopover behavior is often studied on a single species, limiting the generality of inferences
