Equivalence of Infinitely Divisible Distributions
The Annals of Probability, 1975 If $F$ is an infinitely divisible distribution function without a Gaussian component whose Levy spectral measure $M$ is absolutely continuous and $M(\mathbb{R}^1\backslash\{0\}) = \infty$, then $F$ is shown to have an a.e. positive density over its support; this support of $F$ is always an interval of the form $(-\infty, \infty), (-\infty, a\rbrack$ or

Cryptocurrency Bubbles and Costly Mining
International Economic Review, EarlyView.ABSTRACT This paper develops a model of a cryptocurrency by incorporating mining into the otherwise standard search‐theoretic monetary framework. As usual, multiple equilibria exist. To obtain a sharp prediction on whether a cryptocurrency' s value will last in the future, I propose a notion of equilibrium refinement based on the feature that mining ...

Bank Monitoring with On‐Site Inspections
The Journal of Finance, EarlyView.ABSTRACT Using proprietary transaction‐level data on nonsyndicated construction loans, we provide some of the first empirical evidence on the drivers and consequences of bank monitoring through on‐site inspections. Banks trade off monitoring intensity with favorable origination terms.

Share to Scare: Technology Sharing in the Absence of Intellectual Property Rights
The Journal of Industrial Economics, EarlyView.ABSTRACT Cournot duopolists choose between sharing their technologies, for example, through scientific publications, or keeping them secret. The disadvantage of sharing efficient technologies is that a less efficient competitor imitates and becomes tougher.

Perfect powers in products of terms of elliptic divisibility sequences
, 2016 Diophantine problems involving recurrence sequences have a long history and is an actively studied topic within number theory. In this paper, we connect to the field by considering the equation \begin{align*} B_mB_{m+d}\dots B_{m+(k-1)d}=y^\ell \end ...

Journal of Management Studies, EarlyView.Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...

Achievements and Fallacies in Hume's Account of Infinite Divisibility
Hume Studies, 1994 Throughout history, almost all mathematicians, physicists, and philosophers have been of the opinion that space and time are infinitely divisible. That is, it is usually believed that space and time do not consist of atoms, but that any piece of space ...

Noûs, EarlyView.ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

Leibniz, the Young Kant, and Boscovich on the Relationality of Space [PDF]
, 2016 Leibniz’s main thesis regarding the nature of space is that space is relational. This means that space is not an independent object or existent in itself, but rather a set of relations between objects existing at the same time.
