Improved Precision and Reference Materials for Stable Carbon Isotope Measurement in Basaltic Glasses using Secondary Ion Mass Spectrometry

Geostandards and Geoanalytical Research, EarlyView.
Key Points High‐precision measurement results for δ13C in basaltic glasses were achieved down to 25 μg g‐1 CO2 using a refined measurement procedure via large‐geometry SIMS. Three new hydrous basaltic glasses (ETNA24, ETNA32, ETNA36) were established as reference materials.

Genetic Insights: Balancing Milk Yield, Fat: Protein Ratio and Fertility in Primiparous Cows From Subtropical Regions

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In this study, we aimed to evaluate the genetic association between fertility traits, milk yield and the fat: protein ratio (FPR) on the test day in primiparous Holstein cows. The analysed traits were milk yield (TDMY) and FPR assessed on the test day, as well as the following fertility traits: period from calving to first service (CFS), days ...

Pollution Permits and Financing Costs

Journal of Money, Credit and Banking, EarlyView.
Abstract Effective environmental policy should consider how the financiers of polluting firms behave. We study phase III of the EU Emission Trading System. Loan spreads for cap‐and‐trade participants are a function of compliance costs, permit market features, and firms’ strategic actions.

How much are we willing to pay for quality wine? A meta‐analysis and meta‐regression analysis

Journal of Economic Surveys, EarlyView.
Abstract This paper performs a meta‐analysis and a meta‐regression analysis on the price semi‐elasticity of wine quality ratings in the context of estimating hedonic price functions. To do so, we thoroughly search for publications that have estimated hedonic functions in this market, resulting in 223 articles estimating 1595 functions, although not all

Regulating Over‐the‐Counter Markets

The Journal of Finance, EarlyView.
ABSTRACT Over‐the‐counter (OTC) trading thrives despite competition from exchanges. We let OTC dealers cream skim from exchanges in an otherwise standard Glosten and Milgrom framework. Restricting the dealer's ability to cream skim induces “cheap substitution”: some traders exit while others with larger gains from trade enter.

Fractional gaussian noise: Spectral density and estimation methods

Journal of Time Series Analysis, EarlyView.
The fractional Brownian motion (fBm) process, governed by a fractional parameter H∈(0,1), is a continuous‐time Gaussian process with its increment being the fractional Gaussian noise (fGn). This article first provides a computationally feasible expression for the spectral density of fGn.
