Universality of the Volume Bound in Slow-Roll Eternal Inflation [PDF]
, 2012 It has recently been shown that in single field slow-roll inflation the total volume cannot grow by a factor larger than e{sup S{sub dS}/2} without becoming infinite.

The hole in the doughnut: Formalizing and testing a key model of degrowth
Contemporary Economic Policy, EarlyView.Abstract Degrowth scholars often claim that capitalism generates social and ecological imbalances, as captured by Kate Raworth's leading doughnut model. We formalize this model using social and environmental indices and measure imbalances using their coefficient of variation.

Eternal Inflation: When Probabilities Fail [PDF]
, 2018 In eternally inflating cosmology, infinitely many pocket universes are seeded. Attempts to show that universes like our observable universe are probable amongst them have failed, since no unique probability measure is recoverable.

Asymmetric sanctions and corruption: Theory and practice in China
Economic Inquiry, EarlyView.Abstract Asymmetric punishment of partners in crime, intended to incentivize whistle‐blowing, may increase detection and deterrence. The idea is age‐old but its use against corruption is not frequent. We study a 1997 Chinese reform that strengthened such asymmetries for some forms of bribery.

Sharp predictions from eternal inflation patches in D-brane inflation
, 2017 © 2017 IOP Publishing Ltd and Sissa Medialab srl . We numerically generate the six-dimensional landscape of D3-brane inflation and identify patches of eternal inflation near sufficiently flat inflection points of the potential.

End-of-the-world branes and inflationary predictions for rocky and swampy landscapes
Journal of High Energy PhysicsMaking cosmological predictions in a multiverse is a fundamental theoretical challenge. Assuming that (quasi-)de Sitter vacua are quantum mechanically described by a finite-dimensional Hilbert space, we develop a detailed framework for making explicit ...

Managed decline: Muddling through with the Sterling (dis)Agreements, 1968–74
The Economic History Review, EarlyView.Abstract How do policymakers manage the decline of an international currency? This paper revisits the view that the ‘Sterling Agreements’ of 1968–74 – bilateral contracts between the UK and sterling‐holding governments – marked a successful paradigm shift towards sterling's managed ‘retirement’.

The depth and breadth of capitalism at the Cape
The Economic History Review, EarlyView.Abstract Limited liability company legislation was introduced to the Cape Colony in 1861. An amendment in 1892 led to wider adoption, expanding and diversifying the capital market. Using novel data from the Cape Joint Stock Archive between 1892 and 1902, this paper examines who invested, where capital flowed, and how these patterns shaped firm outcomes

The Constructibility Principle
Философия и космологияThe issue with current scientific models is that many models are speculative or paradoxical constructions central to Philosophy and Cosmology. The Constructibility Principle in this paper introduces a demarcation criterion.

Do Banks Learn From Natural Disasters? Evidence From the U.S. Financial Sector
European Financial Management, EarlyView.ABSTRACT This paper examines whether U.S. banks learn from natural disasters. We explore several potential channels of adjustment and find that exposed banks primarily respond by adopting precautionary capital measures. This behaviour is evident both in the long run, when assessing divergent trends in the evolution of equity over time, and in the short
