Despite the growing importance of the digital sector, research on economic complexity and its implications continues to rely mostly on administrative records—e.g. data on exports, patents, and employment—that have blind spots when it comes to the digital economy. In this paper we use data on the...

This paper evaluates the role of climate variables in predicting international migration by proposing two alternative modeling approaches: scalar-on-composition and scalar-on-density regressions. We compare them with the standard scalar-on-scalar approach. Although most studies rely on annual...

A major mathematical difficulty in studying extreme value parameter estimators defined as empirical mean excesses is their reliance on high order statistics above a random threshold. Based on simple yet novel derandomization arguments, we provide sufficient conditions for deriving the joint...

We consider the global optimization of a non-convex potential U : Rd → R and ex tend the controlled simulated annealing framework introduced in [31] to the class of swarm gradient dynamics, a family of Langevin-type mean-field diffusions whose noise intensity depends locally on the marginal density...

This paper studies the efficient allocation of capital and consumption in a production economy with many agents, private information, and aggregate risk. It extends the influential work of Andrew Atkeson and Robert E. Lucas Jr. (1992), who analyzed a related problem in an exchange economy. In a...

More than a decade after COP21, carbon emission trajectories remain far above the 1.5° C threshold, due to lack of international consensus. Departing from cost-benefit approaches, we assess the maximum reduction in carbon emissions that could be accepted by all countries. We characterize the target...

In econometrics, the impact of climate change on agricultural yield has often been modeled using linear functional regression, where crop yield, a scalar response, is regressed on the temperature distribution over a given time period, treated as an ordinary functional parameter, along with other...

Motivated by the forthcoming terminations of most highways concessions in France, we propose a versatile model of dynamic regulation and contract renewals that describes a long-term relationship between the public authority and an incumbent operator with private information about its costs that may...

The impact of YouTube’s recommendation algorithm has been subject to much debate. Case studies and anecdotal evidence have suggested that algorithmic recommendations may lure the platform’s users into informational ‘rabbit holes’ where they are exposed to biased content and misinformation. However...
