This paper proves that the separation convergence toward the uniform distribution abruptly occurs at times around ln(n)∕n for the (time-accelerated by 2) Brownian motion on the sphere with a high dimension n. The arguments are based on a new and elementary perturbative approach for estimating...

This paper investigates pooling strategies for tail index and extreme quantile estimation from heavy-tailed data. To fully exploit the information contained in several samples, we present general weighted pooled Hill estimators of the tail index and weighted pooled Weissman estimators of extreme...

Using jointly geometric and stochastic reformulations of nonconvex problems and exploiting a Monge-Kantorovich gradient system formulation with vanishing forces, we formally extend the simulated annealing method to a wide class of global optimization methods. Due to an inbuilt combination of a...

We develop a model of within-firm sequential, directed search and study a firm’s ability and incentive to steer consumers. We find that the firm often benefits from adopting a noisy positioning strategy, which limits the information available to consumers. This induces consumers to keep searching...

Urban outputs, from economy to innovation, are known to grow as a power of a city's population. But, since large cities tend to be central in transportation and communication networks, the effects attributed to city size may be confounded with those of intercity connectivity. Here, we map intercity...

We argue that education's effect on political participation in developing democracies depends on the strength of democratic institutions. Education increases awareness of, and interest in, politics, which help citizens to prevent democratic erosion through increased political participation. We...

Researchers investigating the evolution of human aggression look to our closest living relatives, bonobos (Pan paniscus) and chimpanzees (Pan troglodytes), as valuable sources of comparative data.1,2 Males in the two species exhibit contrasting patterns: male chimpanzees sexually coerce females3,4,...

The use of expectiles in risk management has recently gathered remarkable momentum due to their excellent axiomatic and probabilistic properties. In particular, the class of elicitable law-invariant coherent risk measures only consists of expectiles. While the theory of expectile estimation at...

Informational capacity is widely viewed as a fundamental dimension of state power and a factor of economic development. However, there is little direct evidence on the consequences of historical investments in legibility. I analyze the case of the French Napoleonic cadaster, an ambitious land...

The rise of mass politics is conventionally attributed to state expansion and economic modernization. We propose a complementary institutional explanation, highlight-ing how the expansion of voting rights politicizes the general public and enhances their mobilization capacity. To test this argument...
