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 ...

Does Survey Angling CPUE Reflect Population Density of Northern Pike (Esox lucius) in Small Boreal Lakes?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Knowing the relationship between catch per unit effort (CPUE) and population density is crucial for the management of recreational fisheries. We conducted standardized angling for pike in 16 lakes (3.4–22.1 ha) to test whether lure type, color, and pike density affect CPUE and the size of captured fish.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

The cost of regulatory delay: quantifying how permitting timelines affect offshore wind energy costs

Environmental Research Letters
Rapid deployment of offshore renewable energy and transmission infrastructure can be a major contributor to energy system decarbonization. However, regulatory obligations frequently impose deployment delays that are typically not quantified in cost terms.

Under the Surface: Subsea Infrastructure and Everyday Geoeconomics in the European Union

JCMS: Journal of Common Market Studies, EarlyView.
Abstract The European Union (EU) is undergoing a geoeconomic shift driven by concerns over its global position, geopolitical tensions and the need for strategic autonomy. Scholars have studied various parts of this ‘geoeconomic turn’ aiming to secure Europe's position in the world.

Electric field determination of polymeric dc power cable in the presence of space charge

, 2007
Space charge in polymeric power cables has been previously measured by the pulsed electroacoustic (PEA) technique and its influence on electric field distribution has been estimated assuming that the conductivity is independent of electric field. In this

Impact of light pollution on fishes: Mechanisms and ecological consequences

Journal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

Fault location and diagnosis in a medium voltage EPR power cable [PDF]

, 2012
This paper presents a case study on fault location, characterization and diagnosis in a length of shielded 11 kV medium voltage ethylene-propylene rubber (EPR) power cable. The defect was identified on-site as a low resistance fault occurring between the
