Risk premia reconsidered: Illiquidity and selection bias for stocks and corporate bonds in the pre‐First World War period

The Economic History Review, EarlyView.
Abstract Financial history is plagued by a visibility trap. Using the Brussels Stock Exchange (1850–1913), we demonstrate that asset illiquidity introduced selection bias, which systematically inflated historical risk premia. Applying a latent return model, we argue that correcting for this illiquidity decreases the equity and corporate bond risk ...

Eternal inflation and collapse theories

, 2023
The eternal inflation problem continues to be considered one of standard's cosmology most serious shortcomings. This arises when one considers the effects of "quantum fluctuations" (QF) on the zero mode of inflaton field during a Hubble time in the ...

Reimagining State Aid: Guiding Law and Policy Reform in a Changing World

European Law Journal, EarlyView.
ABSTRACT EU state aid law has shifted fundamentally from an originally purely repressive tool to a proactive steering mechanism for critical EU goals today. This paper argues that the current legal framework in Article 107 TFEU is gravely misaligned with this new function.

No-boundary measure in the regime of eternal inflation

, 2010
The no-boundary wave function (NBWF) specifies a measure for prediction in cosmology that selects inflationary histories and remains well behaved for spatially large or infinite universes. This paper explores the predictions of the NBWF for linear scalar

The Tipping Point: Interest Rates and Financial Stability

Journal of Money, Credit and Banking, EarlyView.
Abstract This paper studies the impact of interest rates on bank stability in a standard bank‐run model. Banks invest in long‐term assets, whose value decreases with interest rates, and set deposit rates to optimally insure depositors' liquidity risk.

The Evolution of Quantitative Equity Investing: Half a Century of Alpha Research and Institutional Adaptation

Journal of Economic Surveys, EarlyView.
ABSTRACT This survey interprets the evolution of quantitative equity investing as a history of changing constraints rather than a succession of increasingly complicated forecasting models. Portfolio theory made diversification calculable; characteristic‐based investing converted value, momentum, profitability, and low‐risk effects into scalable ...

TCC in the interior of moduli space and its implications for the string landscape and cosmology

Journal of High Energy Physics
We consider the classical Friedmann-Robertson-Walker solutions that describe a universe undergoing a transition from an accelerating expansion phase in the past to an eternal decelerating expansion phase in the future, driven by a scalar field evolving ...

Longevity, Health, and Housing Risk Management in Retirement

The Journal of Finance, EarlyView.
ABSTRACT Annuities, long‐term care insurance, and reverse mortgages remain puzzlingly unpopular to manage post‐retirement longevity, health, and housing price risks. We use a flexible life‐cycle model structurally estimated with a unique stated‐preference survey experiment of Canadian households to understand why. Key factors include high risk aversion,

Eternal inflation and the quantum birth of cosmic structure [PDF]

, 2019
We consider the eternal inflation scenario of the slow-roll/chaotic type with the additional element of an objective collapse of the wave function. The incorporation of this new agent to the traditional inflationary setting might represent a possible ...
