Innovation, firm size distribution, and gains from trade

Chen, Yi-Fan; Hsu, Wen-Tai; Peng, Shin-Kun - In: Theoretical Economics 18 (2023) 1, pp. 341-380

Power laws in productivity and firm size are well-documented empirical regularities. As they are upper right-tail phenomena, this paper shows that assuming asymptotic power functions for various model primitives (such as demand and firm heterogeneity) are sufficient for matching these...

Conditional excess risk measures and multivariate regular variation

Das, Bikramjit; Fasen-Hartmann, Vicky - In: Statistics & Risk Modeling 36 (2019) 1-4, pp. 1-23

regular variation. We show that regular variation on different subspaces of the Euclidean space leads to these risk measures … exhibiting distinct asymptotic behavior. Furthermore, we elicit connections between regular variation on these subspaces and the … under multivariate regular variation. We use a variety of examples to exhibit where such computations are practically …

Behme, Anita; Strietzel, Philipp Lukas - In: Queueing Systems 99 (2021) 1-2, pp. 27-64

In this article, a special case of two coupled M/G/1-queues is considered, where two servers are exposed to two types of jobs that are distributed among the servers via a random switch. In this model, the asymptotic behavior of the workload buffer exceedance probabilities for the two single...
