The importance of considering regimes in long‐term asset allocation to real estate

Real Estate Economics, EarlyView.
Abstract We investigate the long‐term, regime‐dependent asset allocation of an investor's wealth in a mixed‐asset portfolio that includes publicly traded real estate. We show that augmenting standard VAR models with Markov‐switching features not only improves predictive power for asset returns but also introduces economically meaningful horizon effects

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Storage games

The RAND Journal of Economics, EarlyView.
ABSTRACT We study a long‐horizon, oligopolistic market with random shocks to demand that can be arbitraged by two storage operators with finite capacity. This problem applies to any storable commodity—that is, most commodities. Because the arbitrage spread is so sensitive to market power, storage operators face strong incentives to restrain quantities ...

Automated counting of fish in moving diver‐operated videos (DOV) for biodiversity assessments

Methods in Ecology and Evolution, EarlyView.
Abstract Underwater video transects are crucial to assess marine biodiversity and biomass. Counting fish in these videos is labour‐ and time‐intensive and operator‐dependent. Automating this step would create non‐biased biodiversity data and decouple the data collection campaign from any field constraints.
