Environmentally adjusted productivity growth and shadow prices for dairy farms

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Intrinsically localized chaos in discrete nonlinear extended systems

open access: yes, 1999
The phenomenon of intrinsic localization in discrete nonlinear extended systems, i.e. the (generic) existence of discrete breathers, is shown to be not restricted to periodic solutions but it also extends to more complex (chaotic) dynamical behaviour. We

Informing spatial conservation prioritization with species’ traits

open access: yesConservation Biology, EarlyView.
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Call Me Maybe: Corporate Bond Prices Upon Missed Call Opportunities

open access: yesFinancial Management, EarlyView.
ABSTRACT In a sample of discretely callable corporate bonds, we find excess returns of approximately 40 bps realized on the release of the issuer's decision to call or not to call. The bonds that could have been profitably called (in‐the‐money bonds) but are not called contribute the most to the bond price jump. We attribute the jump to the revaluation
