On Metric Choice in Dimension Reduction for Fréchet Regression

International Statistical Review, EarlyView.
Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

Estimation of Genetic Variance and Breeding Values for Infectious Disease Susceptibility From Simulated Longitudinal Data Using Generalized Linear Mixed Models Based on Transmission Dynamics

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent theoretical work shows that the potential of genetic selection to reduce the prevalence of infectious diseases is much larger than expected from classical quantitative genetic theory, due to indirect genetic effects that arise in the transmission process. However, to fully benefit from these indirect effects, we need to estimate genetic

Somebody Knows Something: Managerial Ability, Product Development, and Return‐on‐Investment in a Hit‐Driven Industry

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT In hit‐driven industries, product development is associated with a right‐skewed unconditional distribution of performance, and products in the right tail have outsized impacts. Understanding how exceptional performance is generated can improve resource allocation, but the literature advances two different narratives: one emphasizes postrelease

Field Attraction of Natural Enemies to Methyl Salicylate Differs Between Annual and Perennial Cropping Systems

Journal of Applied Entomology, EarlyView.
ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

Journal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

Climate‐Neutrality Transition and Banks' Loan Pricing

Journal of Financial Research, EarlyView.
Abstract In this paper, we propose a novel methodology to quantify firms' climate‐change transition risk (CCTR) and its implications for credit markets. We utilize the regulatory framework of the European Green Deal's 2050 carbon neutrality roadmap, focusing on large Eurozone firms and their banking relationships.

Financial Fragility and the Fiscal Multiplier

Journal of Money, Credit and Banking, EarlyView.
Abstract We show that undercapitalized banks with large holdings of government bonds subject to sovereign default risk lead to a new crowding‐out channel: deficit‐financed fiscal stimuli lead to higher bond yields, triggering capital losses for the banks. Banks then cut back loans, which reduces fiscal multipliers.

A Unified Approach to Estimating Production Functions: Proxy Variables and Dynamic Panel Data

The Journal of Industrial Economics, EarlyView.
ABSTRACT We propose a new approach to production function estimation that integrates the strengths of the proxy‐variable (PV) and dynamic panel data (DPD) methods. Our framework augments the set of instruments for the level equation in Blundell and Bond [8] with a Berkson‐type instrument motivated by economic theory, following Olley and Pakes [28 ...
